Hey all,
We bought a property with an old 30sqm bitumen felt octogonal flat roof above the main bedrooms. It has been described as watertight but with ponding. We are also suffering a lot with overheating in the summer from heat transfer from the roof, and I imagine that the insulation under the felt is also not great given how old the roof is.
I am completely lost as this is the first time I have dealt with roofing. I have done some research, but want to ask the experts:
What would be some suggestions on hot to improve the reflectivity/insulate? Can I get by by simply coating the existing roof in some reflective paint? Or should I consider a full replacement? The first roofer that came over ofc said that it was urgent to replace but that is expected.
If replacing, I have been told that fleece backed epdm would be a great option. A lot of people in the UK try to do GPR but I don't want that. I understand that EPDM would not easily paintable and that it is not great a solar reflectivity, what would you do in my case to have a long lasting roof that also has good thermal insulation? Would EPDM + PIR layer between the joists be acceptable?
I'm starting to get companies to come in and give quotes. Any other things I should be asking the roofers?
