I have a few shingles on my roof that have been blown off. I'm pretty sure that I have shingles remaining from the original roofing job, how do I replace those shingles that blew off? Thanks for your help.

 

Cut the top 1" off the top of the replacement shingle. Trowel a little mastic on both sides of the replacement shingle along the top edge, about 2" wide. Slide the shingle up and under the next shingle and (holding the above shingle up and out of the way) and nail w/6 nails along the nail line. A few dabs of mastic on the upper shingle to get it tabbed back down.

Never heard of cutting off the top inch of the new shingle but I guess it wouldn't hurt anything.

Here's what I do to replace shingles. With a hammer, hook blade, hand nails and pry bar in hand and a couple shingles close by I first pry up the shingles above the missing ones to make for an easy slip under. If you pull out nails you should put a little bit of tar in the hole or put some ice and water over the hole to ensure no leaking in the future if the same shingles should blow off again. If only one tab has blown off you can cut out the tab and install just one tab instead of the whole shingle. Line up your new tab or shingle and nail right below the tar line but make sure the shingle above the ones you nail will cover the nail head. To ensure the shingle will stay on the roof some tar applied under the tab an inch from the outer edge will work good, make sure you don't do to big of a bead so when you step down on the shingle to seal it you don't want tar leaking out and getting on your roof.


Good luck and this is really an easy do it yourself job.
