How Often Should Roof Shingles Be Replaced?

If you discover any damage or signs of wear, take action right away to avoid water from seeping beneath the shingles and causing the wood sheathing beneath to decay. Roof replacement's earlier phases are less expensive than its latter ones because they don't require additional materials or labor. Ignoring a problem—even one that appears to be minor—can lead to higher roofing costs and thousands of dollars in repairs.

Pro2Pro Tip: On a hot, dry day, repair damage to the shingles' suppleness and minimize the chance of shattering. Never go on a wet, icy, or foggy roof before sunrise.

It's time to replace your roof if the majority of the shingles are faded or damaged, and it's more than 20 years old. However, if your roof is in good shape and has a modest slope that you're comfortable working on, most repairs may be handled by a do-it-yourselfer.

Here, we'll go through the three most common reasons for shingles to break: replacing asphalt shingles, repairing badly curled ones, and gluing down a bent shingle.

Replacing roof shingles depends on how big is the damage dealt in the roof

1. Replacing Roof Shingles

Remove the damaged shingle by using a flat pry bar and pushing down on it to remove the roofing nails.

A missing shingle will have to be replaced entirely. Check for any remaining shingles from the previous installation if you don't find any (with luck, the builder or the roofer who completed the work left some behind). You can't just buy a set of shingles and expect them to look great. Most likely, you'll have to buy a bundle from a home center or lumberyard ($15 to $20 per square—100 sq. ft.). If you can't discover an exact match, go with the nearest option.

An extra-large roofing nail, a pry bar, and a utility knife are all you'll need to repair or replace a damaged or broken shingle. Each shingle is secured with four nails at first; however, as the subsequent course's nails pierce through the top edge of the preceding course's shingles, their number also increases by two.

Remove the first row of nails by sliding the pry bar under the shingle just above the damaged one and carefully lifting it away from the sealer strip. The first row of nails will be revealed.

Remove the damaged shingle by prying upward with a pry bar. Remove the pry bar after the nail has risen approximately 1/4 in. Once you've pressed down on the shingle and pulled out the nail. Repeat this process for the remaining three nails. Then, beneath the cracked shingle, use the pry bar to lift the second row of nails in the same manner as you removed the first. Remove the damaged shingle using all eight nails after pulling it out of its groove.

2. Corners of a curling shingle roof that have been damaged should be repair with caulk.

Remove the old shingles and replace them with new ones. Make sure you're lining up with the shingles on either side. Asphalt shingles will tend to curl downward or upward as they get older. If you find that a shingle is beginning to curl, you can glue it down to prevent it from curling.

Use a caulking gun to apply a tiny amount of roofing sealant (about $4 per 10-oz. tube) along the corner. If you choose a more expensive option, make sure the brick is secure in place for at least 24 hours while the sealant cures. That's all there is to it.

3. Cracked Roof Shingles Repair

Lift the upper shingle and secure the replacement shingle with roofing nails carefully.

If a shingle is merely broken or shredded, you don't have to replace it—simply repair it. Begin by laying down a thick layer of roofing putty under the crack. Remove any loose shingles and debris before pressing the shingle down to cure it. Then use a putty knife to smooth out the sealant.

The good news is that you won't be required to explain what you did. It's easy to conceal: Look for a buildup of colorful granules in the gutter that have come down from the shingles. Gather a few in a tiny cup and sprinkle them over the sealant to disguise the repair.

Can I use roof sealant over shingles?

No, you cannot use roof sealant over shingles. Roof sealants are only meant for asphalt roofs. Roof sealants will damage or destroy any other type of roof, including wood shingle roofs.

What do I need to know before putting on a new roof?

Here are five things to keep in mind when repairing your roof:

If the repair is not critical, patch it with ApoPatch Repair Putty

which will allow the original manufacturer to replace the section at their discretion without notice. If you wish to indicate that an area has been repaired please affix ApoPatch Repair Sticker on top of the putty layer and cut off any excess sticker material with a utility knife after applying putty.

That shingles can easily be damaged by wind.

Sealing the edges of the roof is not something that many people have to do very often, but it's extremely important if you happen to live in an area where high winds are common. If your roof does not have proper protection around its perimeter, then water will run right into the attic and cause major damage to the insulation, ceiling drywall, wood beams, rafters, trusses... pretty much everything else up there.

All roofs require some kind of sealant

All roofs require some kind of sealant along their seams so that water cannot seep through any gaps or cracks. This sealant is typically either a caulking material or a compatible adhesive capable of withstanding outside elements for long periods.

If you do not seal your roof properly, then water will seep down into the insulation and cause stains that are very difficult to remove without causing damage to the other materials in the attic.
