Last week I posted a problem with finding a roof leak. Well I managed to get up on the roof a few days ago with a water hose, and I aimed it right at where it was leaking in the attic. Sure enough, when I went into the attic I saw water dripping, so at least I found it rightaway, as opposed to the water traveling from another spot. But even so, when I looked at the spot on the roof, I could not see any damage. I noticed that the edges of the shingles were glued down. Anotherwords the manufacturer had put a thin layer of roof cement under the edges so it would seal by itself in the sun. So I carefully lift the edges breaking the seal, and then water came out. I guess the water was somehow entering the sides and being trapped under the shingle and making its way up to the nail under it. I did this to a few shingles on my roof and noticed the same thing, water coming out from underneath. So I took some roofing cement and with a putty knife managed to cover the nails under the shingles in the spot of the leak. Last night I went to check for leaks during the rainstorm we had, so far no leaks. But has anyone ever heard of this problem? Why are the edges sealed in the first place?
