We've done this post many times, but it's been a while, they've been deleted, it's done every year anyways and we've got new audience members so here it is again. One of our roof's get's damaged at least once a year due to windy storms. It's on the beach and it has 3 tab shingles so they always get ripped out. Replacing shingles is pretty easy. First bring an old ripped one to your local hardware store and match the color with ones similar, then all you do is get a roof crow bar and pull the nails out loosen old shingles and pull the ripped ones. Install new by cutting to size and then add roof cement under new and old shingles which binds them together. Without adding the cement the shingles will just flap in the wind a rip off again, which we somewhat expect anyway's because we're out here doing this job over and over :). Remember to bring a hat and some knee pads, Even with all that your going to have your work cut out on this job. Think desert with hot molten shingles blaring in your face and burning your hands. Fun Times. Eventually when it comes times for replacement we'll replace with dimensional shingles which are one full piece eliminating the 3 tab flap in wind. Problem solved. Oh yeah.. DIY About $40, Hire it out...$300-$600. Ready to get your hands bloody?
