Albert from North Carolina asked:
I have had a lot of shingles come off a new roof from over driven nail. May question is on hip portion some came off and I said there was no paper on the hip. Contractor said paper does not go on hips of the roof. That doesn't seem correct? This is in North Carolina.

John Kenney from Cotney Consulting Group had this to say:
On a typical hip detail on a shingled home, the underlayment should be continuous under the shingles. Sometimes, a self-adhering membrane is used at the hips. On the ridge, this would also be true unless it is vented. If it is a vented ridge detail, the underlayment would not continue over the gap so that proper venting could occur.

John Stout from Go Roof Tune Up shared:
Albert from North Carolina,
Sorry that you are having trouble with your roof. Your letter states that there is no felt paper under the shingles at the hips. The question came up that it was not necessary to have felt under shingles at the hips.
The National Roofing Contractors Association (NRCA) recommends No. 15 Asphalt Saturated Non-Perforated ASTM D226 or ASTM D4869 installed under asphalt shingles. This would include the areas at the hips and ridges. We hope that this information is helpful.
Thank you for your question.
