Charleston Roofing: Article About Restoring Missing Shingles
You've noticed that your Charleston roofing is missing a few shingles here and there, and while this may not be a major problem now, you'd better correct it as soon as possible if you want to avoid significant moisture damage. Fortunately, this doesn't have to be a big-budget job; if you're only going to replace a limited number of damaged patches, you can do it on your own. Here's how to get started.
Many residential shingles are attached with nails, but adhesives are also used to create a tighter fit. If you're going to replace a shingle that is only partially cracked or damaged, you need to remove the old bits first.
Get rid of any nails by carefully prying them out using the claw of a hammer or another appropriate tool. Be careful not to apply too much force as you might damage the surrounding tiles. You can then deal with any adhesives left behind.
With a pry bar, lift the damaged shingle to separate it from the others. It ought to come loose as the bonding agent breaks, but if you find that this is not working, you may have to take the additional step of cooling the tile down. Hot adhesives are a bit springier, so apply some water to cool the area if it's been soaking up sunlight for a while.
After removing the old shingle completely, make sure the affected spot is clean and relatively smooth, but never use abrasives that will compromise the integrity of the roof felt membrane beneath the tiles.

Install the new shingles by following their manufacturer's instructions. When you're finished, be sure to apply a coat of sealant by hand. The previous seal was broken when the old patch of roofing was removed, and it may not do its job if you don't fill in the gap.
This process is a bit different when you need to replace a hip shingle at the crown of your roof. Because these shingles are often lost to wind or similar forces, they don't always break evenly; you might have to remove lingering bits or even some of the surrounding flat shingles that came off as well.
Although some people cut and bend regular shingles to create ridge cap shingles, those that come made for this purpose are more suitable. These shingles are thicker and already bent, so they're less likely to crack under routine stress.
When installing shingles at the top of the roof, be extremely careful; you'll fall further if you lose your footing from here. Follow the manufacturer's instructions as you apply the ridge cap shingles over their new neighbors and any pre-existing ridge vents. In addition to applying asphalt cement or similar adhesives, fix these shingles in place with extra-long fasteners to prevent lifting.
