Danny Lipford: Most homeowners are very reluctant to try some roof repairs themselves, but some of the minor roof repairs are very simple.
Joe Truini: When you have a roof shingle that’s been punctured or ripped by the wind—as this one has—you don’t need to replace it, all you need to do is repair it. Get a piece of galvanized metal flashing and a tube of roof cement.
First, get a flat bar, and pry up the shingles on either side of it and the entire damaged shingle. Then take the roof cement and apply thick bead of cement along the top edge of the flashing, and a narrower one along the bottom edge.
Then take it, slip it underneath—making sure to position it all the way up beyond the course above and on either side, covering the entire tab—press it down.
Then lift up the damaged shingle and put two more beads of roof cement—thank you, Danny. Then you press it down, and the repair is done.
