My roof is 20 years old, so I am getting the asphalt shingles replaced. Over the years I have noticed little bumps in the roof surface from the 1x6 sheathing coming a little in spots. While the shingles are off, I want screws added at places of high risk instead of just new nails. But contractors and my city inspector look at me strangely. Is this really such a strange idea? It sounds reasonable to me. Aren't screws better than nails at holding two pieces of wood together?
Cost is not an issue yet because no one will quote it that way. I have read that this is done in Florida because of hurricanes, so I know there is some logic to my idea. I just can't find someone to do it. I just know that if I get a new roof now, in a few years I'll see more bumps.
I have a 1 1/2 story bungalow built in 1942.
