There's an exetension off the back of my home that is office for business. Whoever built it used cement block walls and poured concrete for th ceiling. Roofing material is rolled roofing. About 5 yrs ago I added a seccond layer of rolled roofing, but now water is somehow getting in. What's the best way to reapir/rplace this to prevent future leaks. The roof is flat with very little pitch so water tends to sit on the roof for long periods. Thanks.

There is a way and not that expensive. First tear off all the old rolled roofing. Then
put down Roof Guard. In some areas it is called Roof Seal. It comes in a roll, is black and is a rubber product about 1/8" thick. It has little holes in it, and is very sticky on one side. Roll it out, and roof over the top of it. It is 100% waterproof. Do not put roof felt over it, just your roofing. If you do use rolled roofing, overlap it about one foot instead of the 6" on the directions. This should work. Also make sure you put up your metal flashing. Run up your wall at least 6" under the existing siding. Good Luck

Do what Jack the Contractor suggested but be sure to mop in tar
at the place where the roofing paper is being overlapped.
