Well, after using the site since April I finally managed to find a roofer and get my house re-roofed. I followed lots of the advice given on here and I think the roof is now better than ever.
I used Elk High Definition shingles, Air Vent Shingle II-9 ridge vent and installed smart vent product to help with intake since I had absolutley none.
The roof has been done for about a week and it’s been pretty warm here (Oklahoma) and so far I am not real impressed with the venting of the attic. My only reason to replace the roof was to address the heat buildup in the attic - sometimes it would reach 160+ which caused the shingles to start curling. I really thought all the changes I made would make a big difference, but so far they haven’t and I am worried now that my new roof will start to curl like the old one did.
I measured the temp yesterday in the attic while the outside temp was 97 degress - it was about 150. I called the contractor I used and he was very nice and said his recommendation would be to install a power vent on the back side of the house to help remove the heat from the attic and rely on the ridge vent for all year ventilation, but use the power vent to assit in the really hot months. He said of coarse this will interfere with the ridge vent working like it should but it may be the only way to really get the hot air out.
I would appreciate any help or advice on what my next step should be.
Thanks in advance!
