Hello Kathy, What I see in the photo's is a botched roofing job. The existing rolled roofing and existing flashing is in question also. To shingle over the rolled roofing is an "easy out" for this roofer. The rolled roofing has been penetrated by walking on it and nailing into it. Mastic, and or "roof patch" is not a way to permanently repair either. That is a "quick fix" I may be too clinical when I roof, but I feel it is the most important part of a house.
# 1 Determine pitch. Standard shingles will handle a 3/12 pitch although with proper underlayment procedure. # 2 Determine if the roof can handle additional load for new shingles or take off all existing compromised roofing materials. # 3 Inspect and replace all compromised flashing @ wall to roof (this may have to be done while re-roofing, and or after re-roofing depending on how it lays" # 4 Re-roof with either composition shingle if pitch can handle it, or use a torch down "dibiten"(this product is used more now in lieu of rolled roofing)
# 5 Get a good roofer to do the job. johnloomisconstruction.com
So we did a big renovation on our house and one of the things that we did was the roof. When we bid the roof I wanted shingles, but was first told that the pitch wasn't steep enough for shingles and we'd have to go with the loose rock that was on there originally. After I was given a price to add pitch to the roof I told them to go with the loose rock. Then my contractor said that the roofer could do shingles and we'd be okay without adding pitch, so I gave them a green light. Cut to the other day when I notice that the part of the roof is shingled and part is not. When I asked the contractor about it he told me that in fact the pitch was not there for shingles so leaving the material under exposed was okay, and if I wanted the roofer would come and mastic (sp?) some shingles on top of the material. I set up a page so you can take a look at the work that's been done. Personally the whole thing sounds pretty hinky to me, but I was hoping for some information so when I have my meeting with my contractor he won't be able to BS me.
