I have a roof that drops 9 inches in 13 feet. Can I use regular shingles instead of rolled roofing? If I go with metal panels,can I fasten them right to the new felt or do I need the 3/4 inch strips.
? Thank you offshoreone

Your roof pitch is less than 1/12 and the minimum for shingles is 2/12 so scrap that idea. The metal roofing manufacturers have their own requirements for their product, the strip is normally required to allow for some air circulation. What brand are you considering?
