I just had a new roof done and as you can see, they used long nails which protruded through the plywood and splintered the wood. I cannot afford to have someone scrape and paint the whole underside of the carport. Can I just have someone spray the whole thing as a quick fix?
I had the same situation one time and the carpenters just put a sheathing over it to hide everything. The sheathing was no thicker that wood paneling and finished very nicely after painting.
The same thing happened to me once. At first I was unhappy because the nails poked though, but then as vin944 stated, its proper for them to protrude through. I talked to the roofers and they gave me some 1/4 in. sheathing. I laid them all out flat on the driveway, painted them, then nailed them up with some help. It looked much better and gave it a finished look.
