- www.homebuildin... Click on this link for helpful videos on home additions, roof framing and repairs. This video will provide you with a basic set of instructions on how you can connect an existing gable roof to a room addition, to form a larger gable roof. There are other ways to connect room additions to an existing house and this is one of them. Make sure you check with a structural engineer before building a room addition or doing something like this to your home.
This video helped out a lot. Taking it a step further with my build. On the existing crown i plan to build a 6ft riser, then bring the rafters down to the addition in order to create a vaulted ceiling inside the new room. Im just trying to figure out if i want to build the walls 10ft or stay with 8ft walls. You just got yourself a subscriber
Thanks for subscribing and I'm glad the video helped.
This video is EXACTLY what I need for my project, thank you!! One question: how would you support/brace the knee wall upon which the new rafters will overlap?
Thanks, this is just what I was looking for. We are planning to possibly add on and was curiuos what would be involved to tie in the roof. We are not tackling this on our own, so this was just enough info to get a half a clue as to what's all involved!
MudRFunR You're welcome and don't forget that their are other ways to build a roof for this type of room addition, I just haven't got around to making the videos yet.
Your demonstration showed a lot in a short space of time, great video thanks.. Any pictures of how that new gable end was reconstructed.
Thank you. Descriptive and cogent. Now I have to find out how to connect this addition to another section of the home with a gable roof perpendicular to the part of the home with this addition!
+John Bruno That's even easier, send me a picture of the side of the home your room addition is going to be attached to and I will make a video. My email address can be found at our website.
We are looking into something similar on our home. The existing structure is 16' wide, and the addition would be 18'. This would push the ridge peak a foot past the existing structure. Could we use bobtail trusses in our case and then overframe between the end of the truss and the ridge on the existing roof? Also, is there such a thing as a vaulted bobtail truss if this were a viable option in your opinion, or would you recommend another method to vault the ceilings in an addition similar to this. Another factor which shouldnt effect anything, is the opposing end of the gable would meet into a perpendicular gable. Thank you!
Great video and perfect for my upcoming workshop addition this fall, which made me wonder if this or a similar method could be done to a variation of a manser roof. My home has manser roof with roughly a sharp 4' ft drop on the last 3ft of roof. If this technique or another one like it would be very practical on a future home addition
Your thoughts or suggestions would be greatly appreciated?
great plan for an open concept 1st floor great room,,,Especially in the snow belt states
My house has a downward sloping gable stopping short of covering a deck. Perpendicular to the deck is a porch with a gable roof centered under a larger house gable. The porch gable sets 1 foot below the soffit overhang of the larger gable. Looking to add a roof over the deck that would tie into the porch and the house.
Here are some RUclips Playlists that might help.

HI. .
My garden is an odd shape, not quite a triangle but more of a quadrilateral.
I want to build a small workshop and use up this odd shape.
On paper from a birds eye view my measurements for the walls are..
Top 2 Meters
Bottom 8 Meters
LHS 8 Meters
RHS 10.5 Meters? I think!
It will all be timber frame construction.
I don't want to put a flat roof on it.
Any suggestions?
Not really, but you can always visit the website for more information.
can a similar addition / gable roof extension be done to a second story instead of a 1 story, that looks just like this? so imagine the same layout but in a 2 story house and the existing addition would be the same type of extension in this video, but the addition would be to a existing second story floor, can provide pictures if needed. The extension / addition would be also over a already existing first floor part of the house that does not have a second floor above it.
Yes, this should work for a similar two story home and addition.
We are in the process of having a gable extension to an existing gable to form a veranda over a raised deck. The existing gable is lower on the north side. How can this be accommodated and still have a level ceiling over the deck?
Wondr8ng same
Been looking for the different wwaayy
My house has an addition similar to the one shown in this video with regard to shape with one exception. The back of my garage stopped short of lining up with the rear wall of my kitchen by 4 feet, so they built a gable roof over this part of the addition and tied it into the existing roof like in this video. For the rest of the addition, the roof is identical to the roof in your video showing how to attach an addition roof to exiting sloping roof, I suppose it's a cross gable. Sorry for the long winded description. My question is, when they connected the new gable roof to the existing roof over the back half of my garage, they left the roof decking (shingles and all) in place. Would it be an issue if I removed this decking to make my attic space larger? My roof was built with rafters.
I don't see a problem and it should improve attic ventilation.
Please make avideo how to installation adu with 2x12 catheral ceiling at living and kitchen, 2x8 rafter above bedrooms and install fasia 2x8 all around the house thanks a lot sir
I put it on my list but no guaranties if or when it will be made and thanks for the video suggestion.
I own a ranch style home, the previous owner built on an addition so the two roof lines are perpendicular. I get ice dams on both old and new parts of the roof, and have installed heat cable around the roof to prevent (any further) damage. I am ready to address the insulation/ventilation issues in the attic. The roof of the original house is still intact under the roof of the addition, except for a 2'x3' cut out. Leaving the structural wood in place, I'm wondering if it's best to cut out the original roof surface to increase ventilation throughout the space?
Yes, I believe you can cut up to a 14" x 14" hole without creating structural problems. It might not be a bad idea to cut a couple of them, but it's a good idea to have air circulating through the entire attic not in separate sections. Remember, I'm not a structural engineer and am only providing you with advice from projects that were approved by an engineer in the past.
is it possible to convert a gable roof into a cross gable, i need to redo my roof, and the house is quite small, was hoping to add some space upstairs in the attic
It will depend on the existing design, but most of the time you can modify the building or home to make almost any design work.
Perhaps this was addressed with the comment about vaulted ceilings. But we want to add an addition much like your picture, but the main (small) structure has vaulted ceiling and as we get out to the end of the gable, it makes for a low ceiling in the addition. How can we have a higher ceiling on the addition?
+Cynthia Tanyan Feel free to email me a simple drawing of what you're looking for and a picture of where you want to put the addition and I will see what I can do.
Looks like this would work well eliminating the old roof framing and sheeting and creating a 2nd story room under the new high ridge in the attic space. With the clear span under that beam, loft room with cathedral ceiling could add another 200 sf or so.
Exactly the type of video I was looking for, THANKS! Quick question if you don't mind... Which would typically be more cost effective for an addition that will travel the length of the house; something like you showed here OR using a gable roof, centered on the existing slope side then flowing outward evenly, kind of like the one you did in the "How To Attach Home Addition Roof Framing To Existing Sloping Roof" video?
I think it would be the other, but it could depend on the length of addition.
Cool, I think either would look good. It would be like a 25Lx12W addition
I will see what I can do.
Thanks, I looked at your website and saw where you were located. I am in the greater San Diego area, do you still do contracting or have you hung up the ole hammer and nails?
About the only work I do is around my home.
Can this method serve to raise the pitch of a Gable roof in order to create headroom space for a loft conversion?
It would depend on the design differences between the two, but I don't see why you couldn't use it if it will work for your project.
@@gregvancom Thanks for replying! I currently have a Gable roof with a 7/12 pitch and my desire is to change it to a 12/12 pitch for a loft conversion. The fact that the new roof could be built above the old new is quite interesting, but I really want to recycle as much of the ‘old’ roof as possible…
We're thinking about doing something very similar to a gable-roofed house that has a very short attic space and an existing addition with a separate gable. We would extend the existing main roof over the addition as you describe here. Trouble is, the stairway is all the way at the opposite edge of the house and we can't stand up on the way upstairs! We were thinking of putting in shed dormers at the same time as the roof extension. Would it make more sense to redesign the whole thing in a gambrel style?
+theuglychuckling If you want, send me some pictures of the existing home exterior and I will see if I get any better ideas.
thanks for this video. How may I ask would you make the addition when you are tying into a trussed roof?
In the same way, but you would need to check with a structural engineer to make sure the truss roof like the conventionally framed roof can carry the additional weight.
good job, im trying to figure out my roof with the layout i have now and its quite difficult.
I am doing exactly this, but I have a truss roof rather than a rafters. In your design, it looks like stress transfer of the roof extension is mostly through the rafters to the load bearing wall between the addition and original, as well as the new wall. With the ridge taking only the load between itself and the original ridge. I would think this set up could go over a truss, but would uneven loading of the truss be a problem?
Remember these are only examples give you ideas, but you would need to check with an engineer to see whether or not you could actually add additional weight to existing engineered roof systems like trusses or conventional framing.
Greg great video's! Currently working on something just like this except the addition is just a 3ft extension on the right. Does it make sense to move the ridge beam or just have the back of the house rafter at a slightly longer run and angle? PS what software are you using for sketches?
There are plenty of options for your project, but it's hard for me to provide you with specific information if I don't know exactly what you're trying to accomplish. Feel free to send me a picture of your house or a drawing or both for more information. You can get our email address at the website.
Once the new roof is installed, Can the old rafters and roofing be removed so the full height of the attic is higher?
Not if the roof rafters are supporting the roof.
Sir I hope this comment fine you well, I’m planning to do the same kind of addition, BUT the addition part is actually going out 3 foot into the left. What can I do to connect the roofs ?
Here's a link to our website, but I think I already sent it to you.

@@gregvancom yes sir you did, thank you so much
Im looking to add a 6' front porch along the front of my home that has a hip roof that has a 45 degree pitch all the way around. Any videos of something like this? Thanks.
I would need some type of drawing, link to a picture or something to give me an idea what you're going to do and you can get our email address at our website.
Hey thanks a lot for this video. I'm purchasing a house that I want to do that exact addition. If you could be so kind I'd like to ask you (of course an engineer when time comes) how I could open up the ceiling adding a ridge beam to have the ceiling height and open up the room. It's at the end of the house so all ducting would end at that room with vents at new walls end.
Thanks for your time
Dave
You wouldn't use this method if you were going to install a ridge beam to make a vaulted or cathedral ceiling. However, stay tuned to my main channel and I will try to make a video within the next few weeks showing you one way it can be done.
Greg your the best that would be so awesome!! I wish I could show you pictures of our proposed home.
Dave Marriott Feel free to email them to me and you can find my email address at the website gregvan.com.
how about venting? does one cut the sheething?
what do you do if you just wish to take the new roof from the top of the old roof (top of the gable) down to the new outside wall?
Can you send me a picture of what you're looking for, even a crude drawing will do just fine. You can get our email address at the bottom of our website.
I was able to work it out thanks all the same, it was a lot like the one in this post only the roof line tied into the ridge , or right below the ridge from the wall up to the ridge.
That's good and good luck on your project.
What if you didn't want any header between the two rooms? Adding an LVL beam means the existing roof rafters would have to be cut. Do you think hangers would be a viable solution? Obviously, hangers would be used for ceiling joists on both sides of beam. I understand the design would need a professional review.
+tommywiseguy Yes, the beam and hangers should work just fine in most cases.
in the picture you didn't remove the roofing material. Would you do that prior to placing rafters.
There is no need to remove any sheathing unless it's going to be in the way of a wall or structural supports. However I would suggest cutting a few holes in the sheathing to provide ventilation between your existing roof and the new room addition.
How do you insulate that new dead attics pace between the old roof and the new roof? An what about Ridge ventilation for the new addition extension reaching beyond the old roof peak?
spray insulation and soffit vents, or a fan anywhere on the roof would work.
What program did you used for this video.
I thought a gable roof has 4 sides versus an A frame's 2. 🤔🤷🏻♀️ My home has roof coming down all four sides, meeting at the corners. Slightly more complicated for an addition, but I was thinking something along these lines-extend current roof at a lesser pitch?
You might find more videos on roof framing and home additions at our website.
how do you measure and cut rafters to meet sloping roof (rafters that run up from existing roof valley on each side of new roof)?
I don't have any videos on cutting roof rafters, but might in the future.
Is there a recommended length for the bridging area when joining to the existing truss stringers when the loadbearing wall is moved? Say you wish to add a room like you have pictured, but take away the former exterior wall so that the new room is open where it meets the existing room. You show the abridgement, but do not discuss this detail.
If I understand your question correctly, you can usually install supporting beams, but if I didn't, feel free to provide me with more details or email me a picture or drawing of what you're trying to do.
Can I do this on a truss roof?
I would think so, but the trusses would need to be measured and built to precise measurements.
where can I get the design software
I guess that would be kind of more support.....right?
Additional roof to existing joist, rafters , same slanted ceiling
What I want to do is to add a long narrow mudroom onto existing raised floor home. The home's block foundation is pretty high off of grade, it is over 140" from grade outside to bottom of rafter tails at exterior siding. My idea is to simply tear back the roofing and sort of extend the rafters via splicing new one's for addition over the existing top plate out to new exterior wall as wide a dimension as I can get away with using the same pitch roof line. My idea is that since this new mud room will be on a SLAB floor WAY lower than home's existing raised floor... that thet difference should give me plenty of extension from existing ... ESPECIALLY given the existing home has 9' ceilings! . I also want vaulted sloped ceiling in mud room so with the far low side at minimum allowable height...which is typically what?? seven feet? Less even?? if it is over a sink and counter area?? Have you or anyone else here ever done such a thing? The added mud room will be like semi outdoor space, Not even on the home's hvac system ...more car portish. Just a nice place where my dogs can sleep when the weather is wet, a place we can come into and get out of wet muddy gear etc....a laundry sink and counter to do clean-up stuff too grimy for house...I envision a door to the outside on the side of house and also a dog door into an enclosed gravel dog run so dogs have a secure place to do their business. It would be so nice for our lifestyle and I am THINKING if it is built more like a covered patio than a "room addition" I can get away with a lot of requirements and expenses associated with a "room addition"!? It will NOT be "living space" For that matter It could have more of a gate than a door at the end to the "outside" ...again has anyone ever done such or seen such? I am still trying to work out exactly how wide I could make it? nine feet maybe since it is a few feet lower already than house floor? And is going from 9' ceiling down to 7' (if I can get away sloped ceiling ending up that low??) Oh yeah the pitch of existing roof needs to be taken into account huh? I am guessing it is maximum 6/12 because the attic is pretty roomy...definitely more of a pitch than typical southern california site built tract home which as I recall were 4/12 or 5/12 ...hm if it falls 6 feet in 12 feet that should tell me how far I can go huh?? If the floor height difference is say AT LEAST 2 1/2 feet and then I get 2 more feet to play with because of existing 9' ceiling in home and lowest point 7' in addition? that is 4 1/2 feet right? that is roughly 2/3rds of 6 feet (6/12 is steepest I think home is now) sooo...I SHOULD...I am guessing? Be able to go out 2/3 of 12 feet which is 8 feet! Right? THAT would work fine for my enclosed covered area I want to use as makeshift "mudroom"/ dog's area! Am I dreaming or would this be doable?? Anyone?
Email me some pictures of what you're thinking about doing and I'll see if I can come up with any ideas.
Thanks man 😘
How do I extend the gable in the same direction as the existing roof.. how do I tie the ridge beams together? New and existing?
Most engineers require you to use a strap to connect two ridges together, but it can also be done with the roof sheathing. This video might help ruclips.net/video/WwU8tGMCTfw/видео.html don't forget to visit our website and check out the videos on the home addition webpage.
I believe I will need an engineer to help me come up with a plan to add an addition to my family room with vaulted ceilings. Removing a load bearing brick wall creating more square footage with a room with vaulted ceilings by building into the existing vaulted ceilings sideways. Is that possible?
montgomb3 It's hard to tell without seeing a picture of your project, but you can contact a contractor or engineer in your area to get a better idea. Make sure you get a few different design options from who ever you contact, along with price comparisons of the different types of projects they are suggesting.
Thank you, sir.
Ok thanks
You're welcome and thanks for watching.
Cheers.
hhmmm,,my client sent me this ..not sure why anyone would do it this way unless you were trying to achieve some massive out of proportion roof and wall. why not just do ridge and end gable ? {the other direction}
I have plenty of other examples at the website and even created a playlist for those who might be interested about other methods for framing home additions. Keep in mind that these examples are not going to work for every project and it sounds like it might not work for you.

Gregvan thanks for those ,,maybe you could answer this.We are building a new front entry /porch that will run perpendicular to existing wall. The existing roof pitch is 4/12,my wife wants to do 6/12,,however the new framing of porch is at the same sill plate height as existing . i think i can make fascia line up by reducing overhang however im worried i may run into a problem with the false valley. Any suggestions ? do you think it will work?
thanks so much
Our neighbor did this and the original roof line is visible from the side of the house. It looks like crap.
I would love to see a picture of what you're referring to. You would need to go to our website to get my email address.
it would save more time to frame in a hip and just have to complete an over build.
You could have also put a gable end on the room addition and tied it back in to the home with two valleys. Remember, this is only one option or way to connect a room addition, but it might not be the best.
wow! wow!... If there is something called a waste of space, then this top space structure will take the 1st prize cake..
Why not put a gable on the end for beauty and run the ridge into the existing roof and over-frame the ridge and jack rafters? this is a strange design to me, a carpenter. The ridge can be one piece thereby reducing much load by cantilevering that ridge over to the existing roof.
There are other ways to build something like this. Feel free to send me some pictures of what you're referring to for clarification as to whether or not your method would be better.
Strange why would you do it this way?
I might not always have an answer for every question in my videos, but actually can answer this one quite easily. Because someone wanted to build it this way.
