I was on here a few months ago and got some brilliant advice for exposed beams that were starting to deteriorate. So I'm back with another question, unfortunately.
When I first purchased my house and would tell people that it has a flat roof, I would get looks of sympathy and didn't really understand at the time. Inspection showed it was good to go for another 7 years but upon doing some work, I've found quite a bit of flaws that were covered up cosmetically by the previous owner of the house.
My latest issue is with the trim that runs along the side of the home. There are random seams (maybe about 10 in total) that all started to leak to various degrees. Instead of sending the water back toward the gutter, it allows water to leak down the seams, which is going to cause some corrosion of the wood in the underside of the overhangs.
I'm not sure how big of an issue it is....whether it's time for a whole new roof or if I can seal these up somehow to keep the seams from leaking.
I assume that they are aluminum but they may be galvanized metal.
Is there a sealant product I can use to keep these from leaking? I haven't looked up above at the roof (I can fairly easily, I just haven't checked it out). I was hoping some kind of DAP sealant would work if I seal it up nice and proper and have several dry days for it to cure. But again, I don't know much about roofs (I am learning more with research) but I wanted to see if anyone had experience with something like this for some potential advice.
Here's a photo of one of the seams..you can see how the water will come down the seam and get to the wood underneath.
I've no problem with stopping the damage to the underside but I know that's futile unless I can stop the problem first and foremost.
Again, any suggestions or advice are greatly appreciated. Thanks in advance.
ps: the debris stuck to the side is just wet leaves that have blown and stuck to it as we just had a pretty bad storm 2 days ago.
EDIT: One more question...I have 2 leaks in the gutter as well that had been welded together.
Is another weld the only proper fix or is there some high powered sealant I could use on that as well? Those must be galvanized steel...the previous owner told me only that they had been welded and that they were custom built and very expensive.
