Hello. We've got a 75 year-old flat-roof home in PA that is need of a new roof. Trying to figure out the best approach.
The roof was last done ten years ago, the roofing contractor used Certainteed stick-down (adhesive) modified bitumen. The product is starting to fail in some places, the ceramic surface is wearing off. The roof leaks, namely where it meets the outside walls or the chimney feature (see photos).
We've had several quotes done, with a range of materials. EPDM, TPO and lastly, torch-down.
Most quotes are for ripping everything down to the wood, replacing bad wood, adding insulation and new surface. I've also had several suggestions to cut the aluminum siding up 6" from the bottom so they can run the material further up the outside walls. This is the source of most of the leaks.
Here are the options I'm wrestling with:
Most expensive: EPDM and TPO
Rip everything down to the subroof, replace old wood, add pitched insulation, wider drain holes. Cut aluminum siding off at bottom and trim off.
Mid-priced: 2 ply Torch Down
Rip everything down, replace old wood, insulation, new drains and do a 2-ply torch-down.
Cheapest: 1 ply Torch Down
Leave current roof in place, and go over top with 1-ply torch-down
Any thoughts? Thanks.
