Repairing Minor Roof Leaks

DIY Questions and Answer June 13, 2012 Sonia

Q.  I have a couple of minor leaks in my roof where sheathing nails have popped up through the asphalt shingles. How do I repair this?

A.  For a popped nail, a short-term solution is to replace the old fastener with a galvanized screw. Pry out the nail with a claw hammer. Choose a screw with a slightly larger diameter than the nail and drive it 2-1/2 to 3 inches into the same hole. The screw will usually grab to the sheathing for a solid connection. Follow up with a bead of waterproof asphalt sealant to fill the hole in the shingle(s). As a long-term solution, it’s best to replace the punctured shingle. While that may seem complicated, it actually only requires a few tools: a pry bar, roofing sealant, putty knife, hammer and roofing nails.
