FAQ
Common questions
How much ridge cap does one bundle cover?
Coverage depends on the exact product and exposure. GAF examples vary by product, so verify the package.
Do hips count too?
Yes. Add hip lengths when the same cap product will cover them.
Should I use field shingles as ridge cap?
Follow the roofing system manufacturer’s installation instructions and product requirements.
