“My home inspector said I need EPDM rubber or something like it because my pitch is less than 1/12 on our addition. I had a roof inspector come and they said to put the asphalt shingles on and then another roofer offered to also put new shingles on…but don’t I need something for flatter roofs?”source ↗
