I have a composition on flat roof. I had a area that had delaminated as

a bubble, as I have been unable to chase a leak, and tore a 8"x8"

section of roofing out, and the paper underneath as this is what I was told to do by a roofer. It has a layer of roofing below I believe. Then I flooded it with Henrys 208R with fiberglass on top and the perimeter, and covered that with the same. I went to the Henrys site and think it said that I should have slit the bubble, pulled it back and taped and coated the patch. Was the way that I did the repair wrong? It is now about 1/4"-3/8" of 208r. It is dry and not raining this week, perhaps in 4-5 days, so perhaps I should have used 205, also recommended on their site. I understand that this stuff does not harden completely. Not sure how long it takes to dry. Should I do anything else. It is in an area that ponds over a bedroom. Help if you can!

Hi,

Water trapped between two layers of flat roofing useually causes the top layer to warp, bubble, crack ect. ect. However the damage visible does not nessecerrily mean that is where the water is comming in. It will accumulate in the low spots, with no way out.

Question is, where the 8" square area where the composition and paper was removed and the void filled with 208R and taped is of concern to me now? Is Henrys robust enough to keep that area sealed, at least through the rains or should I nail a piece of roll sheeting on top of it and tape that? Can anyone help with this?

As long as the surface to be applied is relativly clean of debris, even wet , if you fill a hole and feather the edges, on anything with that stuff, you could get years out of it. Would be smart to apply tape/membrain at the top to stop cracking. The water trapped between layers is still a problem you can`t ignore. Steamming and freezing will destroy all parts of the roofing and framming/sheething system over short time. Look around for other signs of rust, decay, or other suspicious things. A photo or photos would be nice.
