I am replacing a roof for my boss. I have always helped but never taken front on a project like this. Roof is 800 sq feet so fairly small. Tommorow plan is to remove the old roof and prep it so when our other crew shows up we are ready. We have a peel and stick membrane for the entire roof, does this go on first or does the drip edge? I have mostly seen the drip edge first then the membrane. The roof style is a pyramid. On the ridge cap going from the highest point to the lowest point we're the gutters are, what is the best practice? Cut the first membrane along the ridge then on the other side just enough to provide a 3-4 inch overlap from the previous cut?

Hello I recently had a roofer install a new nail over roof over my existing 20 year old 3 tab shingles. The old shingles still looked good and were laying flat . The roof pitch is 12/12 with a open cathedral ceiling. The roof construction is exposed wood beams with 2 x 6 yellow pine tongue and groove wood decking. On top (exterior) of the 2 x 6 decking there is a 3/4" layer of double aluminun skinned foam (not styro foam) insulation. The roofer was aware of the insulation. The roofer did a nail over with GAF 30 year architectural shingles on top of a new layer of 30 lb. felt. Now to the problem. The "installers" used pneumatic nail guns to nail the roofing. During installation, they "blew" the nail heads completely through the new shingles. This happened because the insulation was soft enough that it could not stop the nail head, and the standard roofing nail head simply passed through the new shingles and buried into the foam insulation. If they had used a lower air pressure, the problem could have been avoided. So now I have approx. 15 square of shingles that are just basically laying on my house without anything to prevent uplift from wind. I haven't talked to the original "business owner salesman" as of yet because he won't come back to my house or return my calls. He has sent one of his (I'm betting illegal immigrant) "roofers" back, and he seemed surprised that I knew about the problem. I'm not a ididot, and had already climbed onto the 12/12 pitch and lifted a few shingles (approx 20 in various places) and discovered what had happened. Every nail that I looked at is "blown through". Apparently after talking to the "roofer", he knew that he was having the problem when he drove the first few nails and called his boss....the owner...who told him to proceed as he was. The owner never came to inspect the work as it progressed. If I hadn't inspected the installation (I'm 64 years old and disabled) personally, I don't believe they would have ever said a word about the problem. The shingles have "glued" themselves together after a few hot days, and it's not a problem the average homeowner would have caught.....until the roof blew off in a high wind. My house also has a section of 5/12 pitch roof with plywood decking, and this installation is OK as far as I can tell.....other than wavy shingle lines that are not straight. My total roof is 15 square of 12/12 pitch and 15 square of 5/12 pitch. The only money that I've paid so far was a $2000 down payment to buy the materials... The balance is still in my bank account, and will stay there until I have a proper installation of the 12/12 pitch shingles. This will mean a tear off and re-nailing. I asked why I wasn't informed of what was happening with the nailing and had to discover myself what had happened. I told him that I would have stopped the installation immediately if I knew this was happening. He had no response to that other than the "boss" said to do it. So i now have 15 squares of "new" shingles with a voided factory warranty and a roof that my homeowner's insurance wont cover because of shoddy work. What would you do in this situation? Thanks for reading this long post.
