What can you use to make it stick
I do wonder you've insulated the hole shed is there condensation you have to worry about? On the sealing? I'm not familiar with insulating and I've been told that a roof needs to (breathe) so you don't build moisture and have mold build up ?
Do you have any problems with condensation?
Did you sheetrock it after you put insulation?
Hi Ally, sorry for the late response but your comment was being held for review for some reason. Anyway, there is no need to use anything to make it stick. If they start loosening up you could use some strapping across to keep it in place but I haven't had to.

I have not gotten to the ceiling insulation as yet. However, my plan is not to handle the Rockwool any more than I have to. My plan is to buy panels of thick foam insulation and a fix those to the ceiling between rafters. Much easier to do, easy cutting, and no stone dust in the air. It is the same stuff cemented to basement walls.
Actually my plan is to add that type of insulation under my shed to prevent air from coming up into the shed from outside. I'm going to do that with my builder as the shed will have to be jacked up. At the same time I will be replacing the cinder blocks that were installed there originally with better piers.
Best,
Bob
Thanks for the video and idea. I need to do the exact same thing in our shed. Has it stayed up in the roof without any adhesive or tacking?
Hi Jason, I have had no issues with the insulation coming down on the ceiling. I know of someone who did and he just added some wood cross bracing to hold them up but I have had no issues yet.
Best,
Bob
I have been doing something similar using the same rockwool. I use a box cutter knife that has a blade that can be extended to 4" long. Works fast and easy. Bread knife never worked that well.
Never handle rockwool without a mask...period. Rockwool is rock and DO NOT GET IT INTO YOUR LUNGS. Rockwool is more fragile than I originally thought. It breaks up easily. As soon as I put one bag up, I cover with plastic temporarily until I put up 3/8" plywood wall covering.
Where I will have solar lights (DC) coming out of the wall I will predrill and install wiring in the studs AFTER I put up the rockwool.
It is a very good idea to put in 2 x 6 or 2 x 8 boards between the studs (blocking) where extra supports will be needed for shelves or long screws will be needed to hang heavy things. It is almost never possible to support things from studs only. In addition, be sure to mark on the floor and higher up exactly where the studs are and where the support blocks are located. AFTER you put up the blocking between studs, you can then put in the rockwool.
This is a very nice video. The one common flaw in so many videos is the sound fading in and out. This video does have sound issues, but does have nice text reminders. Very useful.
Thanks for the info C. Kent! Appreciate it.

Everyone is confused with ventilation part plus we're all over the country different cold zones. I think you have to insulate the way your home is. Not the roof itself but the joist .?? That rock insulation is great stuff used it before great sound water insulation. Love to see how everyone is doing it.
Agreed.
Thanks for posting the video. Wanting to insulate our deer camp shed, also with a gambrel style roof. Given that you just posted this video in March, you may not be able to comment yet on how much warmer it is in winter, but I'm curious to know your thoughts. Got pretty cold even with 2 buddy heaters going last winter. Felt like cold was pouring into the shed through the non-insulated floor and walls. Also, any thoughts on insulating under the shed? Ours is far too heavy to lift with jacks and there's not enough space to crawl underneath. May try skirting the edges, but don't want to create condensation issues under the floor. Thanks, JB.
Hi, I added some interlocking square floor tiles to the floor but I should do something better going forward. Maybe you could get some blown in insulation under the floor. I have thought of that and you may not have to jack it up.
Best,
Bob
Hi Bob. On this shed ceiling project, did you end up covering the insulation in the walls and ceiling with something else like paneling or did you leave with the insulation showing? thanks!
Hi Linda,
Sorry for the late response. For now, I leave them exposed. It's a shed and the insulation still works perfectly without any covering of the walls. If we ever want to dress it up we certainly will do so. Thanks so much for your question!.

I bought myself a small tiny 6x8 wooden shed from the shedliquidators. They built it on sight for me so now I just need to paint it. I think if I paint it all white it’ll reflect heat better, but in addition I will insulate this. Your walls have some sort of poly foam insulation I see. Can I also use the same product on the ceiling or must I use the thing you used ?
You can use the same insulation on the ceiling as well. It's just that the ceiling insulation I used has a higher R value. To be honest, for such a small shed as you have, just go with the same insulation I used on my walls. Good luck!
@@TotallyUniqueLife thank you so much. That foam insulation has some sort of aluminum covering on both sides? That’s what it looks like. So basically how that works is heat gets trapped inside the 1 inch foam? This prevents the heat from coming into the space? I can’t wait until my shed is up. My friend is a contractor and he will be constructing it for me for a discounted price compared to the price that Lowe’s is charging. Only downfall is he can’t do it until late July but I’ll wait.
Well, take it one step further. Since I live in a colder climate, my shed is heated. So, the insulation keeps the heat in during the colder months (if it is heated) and the insulation keeps it cooler in the summer and warmer climates. You should talk to your contractor friend about also installing a ridge vent which facilitates ventilation of the shed. Mine was built with one. He will know whether it makes sense in your area.
Good luck with it!
Bob
Have you had any of the battens come down on you or are they holding themselves in place? Also, have you noticed any flaky dust or particles on the items in your shed (or in your lungs) from it being uncovered?
Hi, I have had no issues with battens coming down or any flaky dust. No issues at all since I installed the the insulation. Thanks!
Would you mind sharing what product you used on your floor? The locking square tiles? Thank you!
Hi, I just went to a local Job Lots store and picked up those interlocking tiles. I wouldn't recommend them though because in the summer they tend to shrink and are not flat any longer. It's a pain. I'll probably replace them at some point.
Best,
Bob
Hello, thanks for sharing that. That's where I'm at right now, firsttimer in doing insulation. Smaller shed than yours but I do need it efficient, especially against heat to help the ac I put get to an at least decent temperature. The ceiling spaces are a bit too wide for the rockwool bats, have you seen any being sold wider that the 2x4 ? If not I'll just cut them in parts I guess.
And also by any chance would you recommend or have heard of using reflectix along with rockwool. I have some left over and really want to attack the heat but don't want it to reverse the effects. Its been difficult to find that answer for me.. any input would be great if you can. Thanks !
Hi King,
Thanks so much for your comment. I don't have A/C in my shed but after the last couple of days I am certainly considering that option! Today my shed inside was 79 degrees and outside it was registering 100 for the first time I have seen that with the inside/outside thermometer. Not sure about the battens being sold wider than that but you should look. I bet they do.
I'm not sure about reflectix but I go to this forum all the time for answers and just did a search on reflectix (sawmillcreek.org/showthread.php?114986-insulating-garage-doors&highlight=reflectix) and there are a bunch of posts. You may want to sign up and you could ask your question there. No cost at all and it's a great resource. Let me know what you find out and good luck!

Hey Bob,
Thanks for the reply, I didn't get a notification but remembered to check today.. wow 79 from 100 outside that's awesome ! I will definitely check that resource from forums, take care.
Yeah, that forum is excellent! I know you'll get an answer to your question about using reflectix.

No issue with this insulation holding itself up over time? Looking to maybe use this same stuff on my shed ceiling.
Hi, no issues whatsoever. I recommend it. Good luck!

Hi…Great video..Did the insulation in the ceiling stay snug in between the rafters? Did they ever come loose?
Hi Juan,
Great question. I had a friend who had that issue but, to be honest, my insulation has stayed intact. He ended up adding some strapping across the rafters to hold the insulation but mine has stayed secure. I have been cranking out the heat lately in my shed because the temps are dropping where I live (White Mountains of NH). :-)
If you never need me to take any pictures just provide me an email address and I'll do so without a problem.

@@TotallyUniqueLife Thanks for the info Bob…Will do…Have a great one…
I have a similar shed. I want to insulate. I would like to do it just like you did. But I was told I needed to vent under the insulation or the roof will sweat. Have you had any issues ?
Hi Chad, my shed has a ridge vent already for ventilation.
7:19 they make them 47.5" so you can cut them in half and use them on 24" spaced stud
Thanks Chris! Good to know. Appreciate your input!
Best,

I think I have 24" center rafters on my shed but I will confirm. I think this will work out for me.
Hi Jorge, I would definitely recommend using something other than foam boards on the ceiling due to they don't have a high R value. I forget where you live but I think the winters don't get too cold. But still, using the material I used would be better and would keep it cooler in the heat for sure. Good luck!
@@TotallyUniqueLife My winters I hardly wear sweaters or jackets. My summers are extremely hot here in South Texas. I found the batts you used in 24" but due cost more, about $12 more per bundle. It will be worth it to get at least the ceiling for now.
Well I am very late, but I was curious how this setup has been doing for you? Did you ever install any type of ventilation? Have you had any condensation problems? I'm working on a similar project and was just curious. Love the videos!
Thank you very much for commenting! I have never installed any type of ventilation and have yet to experience any condensation at all (and I check often). Even my carpenter, after he saw my installation, felt it was exactly what he would've done and he wouldn't have installed any baffles at all. I think you could consult a carpenter in your area but for my climate there was no need. Also, my shed stays between 15-20 degrees cooler inside than outside in the hot months. So, apart from being warm in the winter it is also cool in the summer. Good luck!

Bob
From my experience over time especially certain parts of the year you will have trouble with moisture up at your roof. I had a friend who tried to insulate a barn ceiling this way and it started molding after a couple of years and he thought it was leaking but it was because there was so much moisture from the heat exchange on cold mornings. Everything I've read says you have to have ventilation or you have to have some type of gap between the insulation and the roof and that is the problem with a barn type building because they are all built with 2x4s and the insulation like that completely fills up the space. My roof is made where it doesn't even have overhang vents.(They were added after the fact just for looks). if it did you could use soffit vents and put board insulation about an inch thick and then air would flow between the insulation and the roof keeping it dry. I have had a lot of trouble trying to figure out how to insulate a barn style roof like this. But from everything I have been told and everything I have read putting r19 insulation directly up against it is not the right thing to do. Eventually there will be moisture up under it. Any thoughts from anyone would be helpful I have been researching this for a long time everything in my building is insulated except for the roof If I had an A-frame building it would be simple but like I said I have a barn style roof with a loft at both ends.
@@keithkale6538 I too find myself facing a shed with a barn style roof with no overhang vents (soffits) nor a ridge vent. Wanting to finish it as a drywalled ceiling, I also did plenty of research and the case for ventilation seemed to be the only winner. The shed previously had gable vents across opposite walls and a no-power turbine vent fan. The gable vents were sealed off with new siding and only the turbine left. So the dilemma was how to create a ventilation when there was no ridge vent installed and how to avoid creating some type of soffits and use baffles before insulation. It seemed impossible to avoid.
Until I ran across HomeShowRadio episode where Tom answers this epic question of what to do with a scenario similar to ours. Turns out there is an option to bypass ventilation by completely sealing the roof system. Sealing as in not just making sure it is air tight, but creating a R value high enough so that the difference in air outside will not affect the space inside. I felt that should work as I’ve already foamed, sealed and made the barn airtight.
Chek out the episode and let me know if it also makes sense. I’m inching closer to a decision, not wanting to cut a ridge vent in and deal with no space for soffits situation. The only thing to ponder now is whether to keep the turbine vent and if there’s a way to make it helpful in some way.

I am curious about this too, I want to install insulation panels to a garden tuffshed, converted to an office, I am in so-cal, so not the most extreme weather conditions so maybe I dont need to worry about condensation?
I'm thinking of doing the same thing to a new shed, do you think adding sheetrock for a ceiling would make a difference for heating or cooling?
Hi Dan,
For some reason your comment was being held for review and I did not see it until now. Sorry for the late response. I'm not really sure if adding sheetrock would help but when you think about it, it would be an added layer of material so I would imagine it would help in both aspects. I have left all of my walls exposed for the time being. It is a shed! :-)

It would be an extra barrier and it would seal the area more thoroughly Yes
Nicee
Thanks
I’m curious if you have had any problems with mold? Since they’re against the roof sheathing?
Hi Pete,
I check regularly and have had no issues with mold. Great question though for sure given the fact that I have not used baffles or soffit vents. My carpenter friend told me that would be overkill so I'm glad I didn't make that extra investment and labor.
Best,
Bob
Do you need not to worry about ceiling baffles in a ceiling like this?
Hi Dave, please elaborate. My roof has a ridge vent.
Bob
Hows has this held up since 2019? Have you had any issues with condensation at all?
Hi Brad,
Thanks for watching the video and asking your question. My shed has held up perfectly since it was installed. I am constantly checking on condensation and have never found any at all. My carpenter checked out my installation and he thought it was great for the environment in which I live (northern NH, USA). He wouldn't have done anything different.
In fact, we were going to replace the piers underneath the shed and install some insulation under the floors instead of within the shed itself. We are targeting this Spring to do that work as he was too swamped this Fall. It's really a 2 man job and I wanted to do the work with someone who has done this before. I think it's the best solution as my shed is full with heavy woodworking equipment and my Olympic weights. So not having to raise the floor inside and install insulation and a new floor on top would be quite a job. Adding the insulation under the shed is the better option. I will certainly post a video when we do that work.
Thanks,
Bob
Thanks you again. After 3 years, how is the insulation working for you?
Hi, thanks for your comment and question. It is working great. You might want to check with a local contractor on whether or not you should use venting (baffles, soffits) in your climate.
Best,

Do you have to cut roof vents if you insulte it? What about just peak vents?
Hi Pauly, there are varying opinions on venting a shed. You can query this group at sawmillcreek.org and there will be a lot of people a lot more experienced than I am on that particular subject. My shed was built with a ridge vent. How you should vent a shed, from what I understand, also is affected by your location/climate.
Good luck,
Bob
@@TotallyUniqueLife How do you tell if your shed has a ridge vent?
Hi, assuming your shed roof is shingled the top of the ridge will be slightly raised with one line of shingles running down the length of your shed. If you'd like me to send you a picture just send me an email to bobbessette@totallyuniquelife.com and I'll take one and send it out to you.

How do u insulate the ceiling when there aren't rafters?y shed doesn't have standard rafters. Just the trusses
Hi Shannon, I guess you could add rafters or some type of blocking which you could insert the insulation in-between. Another option is to have insulation blown onto the ceiling. I would research this a bit and ask a carpenter for their opinion.
Best,
Bob
where did you get the heater? how much?
I bought it from www.alpinehomeair.com. Bought this one for just under $1000. www.alpinehomeair.com/viewproduct.cfm?productID=453075881
Hey quick question I live in Florida and I’m doing the same thing but I’m trying to live in the shed. It gets pretty hot but I went to Home Depot today and bought insulation and those foam boards and paneling. I was planning on putting in the foam and insulation in the walls but do you think if I just did the isofoam boards that I could keep it cool in there? I have a window unit in it right now but without insulation lowest I can get the temp mid day is about 90.
Hi Shawn, you definitely need to insulate both the walls and the ceiling. Where I live it can be in the 90s and with the insulation I have, it stays about 80 in there without any A/C. So I would say, if properly insulated, you should be able to maintain a decent temp with A/C.
What about your floors? Is there any insulation under the floor? Heat will enter through there if you don't have some type of barrier. This forum is great for answers to these types of questions - sawmillcreek.org/index.php. I visit it often. Good luck and keep me posted!

Totally Unique Life I see conflicting advice on installing a vapor barrier. Do you have any advice on that? I wanting to insulate a shed I’m using for an office for my business and I’m in Mississippi where it’s very humid and hot.
Hi, I would have to defer to this particular group - sawmillcreek.org/index.php . I did not install a vapor barrier and did not see the need for my climate. You will find others in your neck of the woods if you check out that link. There may also be professionals that could guide you better than I could. Good luck and I know you'll find an answer on that site. Even if you just do a search I'm sure you'll get some really good info for your climate.
Best,

Living in Florida, insulating the roof baffles will greatly decrease the life of you’re roof ( suggesting you have a normal shingled roof). It will not give the proper air flow and the heat will do a number. I’d suggest insulating the ceiling rafters instead.
So the RockWool will just stay up on the ceiling? Staples? Adhesive?
Yes, it should just stay up there. I have a friend you needed to add some wooden battens across to hold the insulation in place but I have never had that problem. I guess if your rafters are a little bit further apart you may have this issue but it is easily resolved by just adding some 1 - 2" battens across the rafters to hold them in place if needed. Or you could add some blocking along the side of the rafters to also hold them in place.
But, once again, mine stayed up there without any modifications or additional wood to hold them in place.

Question putting the insulation right up next to the roof like that it won’t cause any condensation when the heat hits the cold roof.
I’m concerned if I do the same there will be moisture up there under the insulation and cause the roof
To rot .
Just a question as I plan on doing the same.
Hi Bobby, first of all my shed roof has a ridge vent (images.app.goo.gl/uMvofbeowDoyaroV8) so that certainly helps venting. Here would be the ideal scenario (images.app.goo.gl/x8eVTi3eYadgu1HVA) where you allow an air gap between insulation and wall or ceiling, include baffles, and soffits to allow the proper air flow. But, this is a shed and I do not cool it with air conditioning in the summer as the insulation keeps it about 20 degrees cooler than the outside air. I know this because I have an indoor/outdoor thermometer in the shed. I do heat it thought in the winter and I have constantly checked for condensation (I just went and checked again) and it's always bone dry underneath the insulation on both the ceiling and the walls. If I were building a garage 3 times the size of my shed and wanted it heated and cooled I would certainly allow for an air gap, install soffits, baffles, and, of course, a ridge vent. But it's a shed and it serves my needs. I also live in the White Mountains of NH so it gets cold but it doesn't get as hot as say Florida. If you are really concerned about condensation build-up, here is a site which you can ask questions of others, some of which are professionals. Here is a thread on venting - sawmillcreek.org/showthread.php?219210-Proper-venting-when-insulating-a-shed-roof&highlight=insulating+a+shed%2C+air+gap%3F.
To reiterate, I have had NO issues with condensation thus far. I also reiterate, it is a shed and not a larger garage or a home. I decided not to invest in what is deemed "proper venting". If it ever because an issue I could adjust what I have done and add an air gap and soffits. It really wouldn't be a major undertaking.
Thanks,
Bob
@@TotallyUniqueLife thanks I think I will just keep I eye on it and check for moisture .
@@bobbylong8372 If you are heating in the winter then putting poly up after the batt insulation is in is a very good idea and very simple. It will prevent any inside warm air from contacting the cold sheathing and condensing. Batt insulation does not have a built in vapor barrier like the foam board does. Just my opinion.
Hi Bobby, I've never heard of putting up the vapor barrier after the insulation. Typically that would go on first between the insulation and the wall or ceiling sheathing. So, if the shed is already built, add the vapor barrier inside and then the insulation (if you are convinced on using a vapor barrier which I have not done). Here is a good article that speaks to using a vapor barrier. Depending on your climate there may be variations. plasticinehouse.com/do-i-need-a-vapor-barrier-in-my-shed/
Here is another one on vapor barriers - shedsforhome.com/what-is-a-vapor-barrier-for-a-shed/ that also talks about using one if you have a concrete floor. This video shows the vapor barrier going on at shed build time outside of the framing - ruclips.net/video/rdMejwdxH9c/видео.html
If the shed is already built you cannot do this but if it is already built you would simply put the vapor barrier on the inside walls and them insulate.
Good luck!
Bob
@@TotallyUniqueLife Bob, I appreciate you responding with links. That is always the best way and I likely should have done the same. However, the first link you posted above actually affirms exactly what I mentioned in my comment above. Under the section *DO I NEED A VAPOR BARRIER IN MY SHED - COLD CLIMATE* the writer states: _"If you use your shed year around as a workspace, you need to insulate and heat it. _*_The vapor barrier should be on the inside of the framing. It will protect the insulation and wooden frame from the warm moist air inside the shed._*_ Moisture that may enter the walls in the summer should be absorbed by the outside air when the temperature cools at night."_ So as I attempted to describe in my previous comment above, in a cold climate the vapor barrier should go "inside" the framing and act to prevent the warm inside air from getting into the wooden framing, insulation and ultimately to the sheathing where it will condense. This is very common practice in cold climates where the indoor temperature is generally higher than the outdoor temperature. The act of putting the vapor barrier behind the insulation and framing as you described above (right up against the sheathing) is definitely correct in hotter climates where the indoor space is generally kept cooler than the outside temperature. This is also mentioned in your same link above. I apologize if this comes across as argumentative as this is not my intent. Love the videos! Keep it up!
There needs to be airflow from soffits and ridge vent.
Agreed.. If this was a larger structure it should definitely need soffits, baffles, and a ridge vent to facilitate air flow from soffits to ridge vent. This is a shed and I have never experienced any moisture behind the insulation in my climate which is the Northeastern US. My shed does not have soffits nor baffles. Believe me I consulted with a carpenter friend and he thought, in this climate, that adding soffits and baffles would be overkill for a structure of this size.
Thanks,
Bob
I think I'm in the wrong zone when people are in snow and winter gear, it's hot as heck in Texas but wouldn't trade it for all the Coronas in Mexico..too soon
Hi, I love the seasons in New England but I certainly can understand why you want to flee the cold! I'm a little different. I like the cold. :-)
Best,

what about baffles what do we do about that?
Hi Reko, I did not install them. If this structure was much larger, like a 2 car garage, I would've considered it. I have had no issues with condensation and the shed heats very well in the winter and stays cool in the summer. There was a ridge vent built into the roof when it was built.
Thanks,
Bob
@@TotallyUniqueLife it looked like you covered the ridge vent. How is the ridge vent venting with insulation inside it?
John,
First of all, this is a 12' X 20' shed. I understand that if you are building a large heated garage or a home, you would always add soffits and baffles to allow the air to flow along the interior of the roof to the ridge vents. I did not install soffits nor baffles underneath the insulation. I could have but even my very experienced carpenter friend said that would be overkill for a shed and where I live. I have always checked for moisture behind the insulation and have never experienced any moisture at all.
So, if you are looking at my shed insulation install as a model on proper roof venting, it was not intended to be. I did what I could with the budget I had given the fact it is a shed and not a much larger structure that would require proper venting.
Thanks,
Bob
No airspace In rafter bays no vents. Big sweat box.
Hi Dwayne, my shed roof has a ridge vent that extends the length of the roof. As you know, ridge vents provide constant airflow along the entire underside of the roof to help remove heat and moisture. My shed stays cool in the summer and warm in the winter. There is also no condensation between the panels and the outside walls as some say to leave a gap between panels and the outside walls.
I beg to differ with your assessment.
Best,
Bob
I would recommend feeling above the insulation in the peak on a very warm day. Even if your roof has a ridge vent, it is likely only venting under the raised metal ribs of the roofing, but the majority of the metal roofing is in direct contact with the roof deck (sheathing), so all of that heat will be transferring into the roof deck. A vented roof has to have airflow from eave to ridge under the majority of you roofing, which means vents in the eaves and a continuous air gap from eave to peak. Even if your roof has vented eaves, you will have blocked that air path with the insulation. The vented ridge cap that shed builders talk about is not the same thing as a vented roof. We had partially insulated a shed roof like you did and had no condensation for a very cold winter, but as soon as the weather got hot, we started getting condensation dripping through the insulation in the peak. Our roof has the vented ridge cap, but it is only venting between the roof ribs and the roof deck. The underside of our roof deck was so hot and damp, the top of our insulation felt like a sauna.
What size is your shed?
Hi Martin, it's 12' X 20'.

How big is your shed?
Hi David,

Thanks,
Bob
Personally I would recommend wearing a mask 😷
Hi Patti,
I did wear a mask most of the time but it was hard to speak and it being loud enough when speaking. So, don't worry, I was safe. :-)
Best,
Bob
@@TotallyUniqueLife plz to hear it. We hear so much about fine dust on the lungs. Great video thanks Bob
I guess your shed is full so mine is about 50% full.
Yeah obviously if I had to do it over I would've insulated at build time! :-)
,,you definitely need a mask a white suit ,or you will choke on glass fibre ,be careful
Hi Ger, so sorry for the late reply but I just noticed your comment. I did try to wear a mask most of the time. Thanks!
Bob
Personally I would have worn a mask so that all those fibres didn't end up in my lungs, but that's just me.
Hi Bill, I really did wear a mask most of the time but I agree with you! I learned quickly that I needed one!
Best,
Bob
