Surface is uneven, mortar is in poor condition, and the weight is breaking the roof.
It's a teardown. You need to replace the decking anyway, so I would do 2 quotes personally.
1: keep the current chimney flues, pull everything else out, rebuild the roof section, box them in with cement sheeting. If they love the look so much you can get fake stone weather boarding to give the look without the weight. A full sheet metal cap with the holes cut will allow you to use a metal roof dektites (Aussie product you can get them on Amazon) to seal the flues.
Quote 2: exactly the same as quite 1 but get a chimney bloke in to change the flues out to modern sizes and better locations. And then you don't need to box and shit, just a modern chimney setup.
It's an expensive job, but it's just not one I would ever bandaid. You are never gunna stop those leaks permanently and eventually that thing will fall through the roof. Ya can't put your reputation on that last blokes work.
Very knowledgeable. Seems like people that have this understanding are fewer and further between as time passes. In regard to work, I think the suggestion of tear down, rebuild and put hardi/vinyl and correct valley intersection and add cricket is proper.....and that's pretty expensive. If the owners budget isn't there for that, depending on hardness of the stone, sometimes a mortar saw can cut a groove into it to counter flash (after tearing out shingles, fixing rot, etc) and then sealing entire chimney with a clear liquid silicone that will repel water if mortar cracks aren't too big (other wise fill larger cracks first then seal). The top cap should be looked at as well.
I can do your roof work and warranty it. You need a mason for the chimney. Please let me know if you hire one and we will accommodate as such. As for your warranty, it covers the roof,,,,,,,, not…… the chimney. Thank you and please sign here.
If you end up doing that job, I wouldn't mind seeing a video on how you fixed it. Just a thought.
It would be great seeing some work done!
I, also, would very much like to see it. It would also put your presentations at a much higher level.
If it was my home, I would relocate the chimney and replace roof.
For starters support the plywood Edge that was not cut on the rafter Center that's why it's sinking tear off all the shingles around the chimney plus vly, saw cut stone four inches up to create a vertical mating face (Aepek is right) for roof to wall step flash saddle stock Etc, peel and stick under, metal, peel stick over and when you put shingles back together I wouldn't bring Nails within 2 ft of that chimney just lay it all in Mastic with minimal nailing I realize you're going to have to use some nails cuz it's Steep and all that but minimize the nails and obviously repoint the mortor with a polymer and I would also either polymer the entire top of the chimney or coat it with elastomeric assuming it's not visible
Complete teardown. Don't even attempt to repair it. Structural support is completely wrong. Putting stone on top of a plywood top is completely wrong.
You had some good ideas. I hope the homeowner takes your advice. All that unsupported weight just seems like a bad idea.
Wow, you're right terrible place for a huge stone chimney.
Unless the owner must have it for looks, I'd want to tear the chimney down, do the woodwork, put modern stacks on and shingle around it.
A lot of work no matter how it's done. Hopefully for the homeowners sake they hire you.
They just built that chimney on top of the roof, without wall support below?
Yup, not structurally sound.
I would only quote the job for a complete removal and rebuild. As long as that heavy chimney, in a bad area, is compromising the roof, I wouldn’t touch it. If someone else gives a price to patch it up, like others have obviously tried, that’s fine, but I wouldn’t do it.
Why would you cut the metal. The cut inside the stone should be straight?
Take it out! The separate stacks with collar flashing is a good idea but they will have to go high enough above the adjacent ridge or roof surface within 10' by 24" min. to vent outlet (check local code). (Possibly the flues will need to be supported by braces)
The stone is able to be ground “flat” so able to flash, and or cut line to embed flashing as well. However, really bad spot for chimney to start w/ and no one thought if this when building the house 🤔, and if do cricket, again, can grind down the stone for “flat surface” to be able to get materials to “mate” to chimney itself, etc….
Hope get this job and show what decide to do; as very interesting….
✌🏻
I hate coming across these on our roof replacements. Sometimes people love to build things and let the crap become the roofers problem lol. I most likely would have tried to add another piece of plywood on the right hand side of that chimney to try and change that valley to spit out past the corner of the chimney at least for the bottom 3 ft or so of set valley. And not for nothing, as much as I cringe with a weaved valley, I would have probably then weaved the whole damn valley if not at least the first three or four feet. There's nothing pretty about a valley being near the chimney. Hate it hate it hate it. I enjoy watching your videos though bud. Been in the field myself for 25 years and I come across the crazy shit ever lol. Keep those videos coming!
They did all that work to replace damaged wood from leak, but they never fixed the original leak? Yikes what a mess.
Stone has to go! Better choice on the market exist, need to fix the flashing issue or what is causing the leak
Point tha valley you could build a cricket run 6x6 piece of metal around it seal it with tons of 4500 and before you do it ice and water shield around it
I would build a cricket also on that stack
Keep up the good work bud 👍
What mess with a roof tar,
Another very informative video!! Thanks! I actually have a fireplace chimney just like that, but mine is 6-feet wide. Mine does not have a chimney cricket installed, and it really needs one, so I will have to research how to measure out and install one when I replace the roof next year. I'm so glad I came across this video now, versus after the new roof is installed, since installing a chimney cricket is a must in my case. Agreed - water pools behind there, backs up, and causes leaks. There are pine trees above my roof, so I make every effort to go up and use a blower to prevent any build-up of pine needles throughout the year. I even go up there in the winter to remove the build-up of snow! When I moved there, the chimney did not have a cap, so I installed one. I also sealed the cracks to prevent any water from seeping in. A few years ago, a roofing company came by and quoted me to have the stone chimney above the roofline trimmed down in width, removing 2-feet on one side, so as to allow rainwater/snow melt, to channel to the sides. I'm surprised that company did not mention to install a chimney cricket, like you mentioned, in my case. Just goes to show, if you want something done right, might as well do it yourself, which is why I'm replacing the roof, and now installing a chimney cricket too. I'll go look through your other videos later to see if any show the install of a chimney cricket that was done, so I can use that as some sort of guide. My 2-cents: in terms of how to mate a chimney cricket to this particular chimney, with its many crevices on the backside that would make it hard to fasten the cricket to, would it be advisable to fill all the voids where the cricket would be mounted to with concrete so that part of the chimney would be flush/solid? Then, when the cricket is installed, you'll have a solid surface to mount/flash to?
Not in this specific case, but how often is the crown the culprit leading to leaks?
When you show roofs that have problems such as this, makes other problems seem minor. Thanks for the education.
There is going to be a lot of work to do to get it repaired.then you may find more issues when you start stripping the roof off.
Are the stone bricks around the chimley a bit to heavy for the roof 😯😯
I disagree, with u blaming leak on stone , ! It all starts with the bad flashing job to begin with , my dude , I’m a plaster and mason , and can tell it’s all on flashing installed bad 😢
My dude! You're made of plaster? Someone installed you bad.
It's not leaking through the masonry or stone, but it is leaking because of the uneven surface and cracks in the mortar.
You can see at the bottom that when they originally did it they used silicone along the top, that didn't work so they returned after the next rain and added the cloth and tar.
Problem is that the silicone will always catch the water in the cracks behind it.
You are right that it's leaking because of the flashing, but that's because it's nearly impossible to flash that face, it needs to be cut in which means your bottom 100mm needs to be level for the right angle to smoothly go into cut in.
It can't be done after the build, long story short knock the whole thing down and build a modern chimney.
I've learned my lesson with stone chimneys like this one. I'm only doing a roof if I can demo the chimney and flash it properly and side the chimney or someone comes in after I flash the chimney and house wrap it and put new stone and a new cap on it. That's just a nightmare waiting to happen
..man all you do is talk about how bad of a job someone else did..that's good 👍 n all..but i have yet ro see you actually make a video on YOU actually shingling a roof..it's easier said then done.
I used to work for someone like that. An armchair general for sure. Knows everything about everything and talks a good game. Never actually seen him do any actual work though. It didn't take me long to figure out he was just a salesman
You must be new to the channel. Brian has many repair videos with him doing the work. Plus, I am sure that he directs his roofing crew "behind the scenes."
