Thermal Proof That Foil Radiant Barriers Don’t Work Directly Under Roofing Shingles

If you’ve ever been told that foil works if you put it under shingles, this video is for you.

This myth (and bad practice) has been around forever and I’m finally taking it head on once and for all. Trust me, no one would be happier if it were true, but unfortunately it’s not. Radiant barrier simply won’t work directly under shingles and I’m going to tell you and *show you* why.

In this video I’ll compare 2 traditional roofing underlayments, a bare deck and RoofingFoil™ + Underlayment on a hot roof.

If your roof system has an air gap (shingles on a double-deck system, metal on battens, tile, etc) then a radiant barrier can definitely work for you. To learn more about the thermal proof of just how good it works when installed properly, check out this video:
