Although sudden roof damage is possible, such as from a storm, most damages start minor and build up over time. Know some of the common types of roof damage so you can spot a problem before it becomes too extensive.

Curling Shingles

Curling is also referred to as cupping in the roofing business. Usually, the loose edge of the shingle first begins to curl at the corners, causing the center to look more depressed and like a cup. This sort of damage can arise from several causes. Sometimes, it is just a sign of age and that the shingles have reached the end of their lifespan.

If your roof isn't very old, then the cause is most likely weathering, with hail damage being most likely. Moisture damage could also be the culprit, particularly if you have debris or moss that sits on the roof for months or even years. Finally, on newer roofs, the problem could be a manufacturing fault with the binders used in the shingles. If this is the case, then the manufacturer's warranty may cover the replacement.

Granule Loss

The granules of gravel on the surface of asphalt shingles serve two important purposes — to protect the asphalt layer from the effects of weathering and the sun. This gravel layer can come off as shingles age, making them more prone to damage, which is one of the reasons shingle roofs have a finite lifespan.

The main reason for premature granule loss is hail. You might first notice the loss when small piles of gravel deposit themselves in your gutters or at the base of the downspout. A small amount of granule loss is normal, but a lot means you have a problem. There may also be shiny spots on the shingles due to the gravel washing off. Once this layer is gone, your shingles won't shed water as well and a roof replacement is necessary.

Loose Flashing

Not all problems affect the shingles. The aluminum strips of flashing that are fitted around chimneys, skylights, and sometimes in roof valleys form a seal between the elements and where these items join to your roof.

Flashing often has a shorter lifespan than the roof itself. A single loose fastener can cause flashing to lift in the wind and become bent or broken. Fortunately, you can have the flashing replaced without replacing the rest of the roof, but you need to spot the damage early before moisture seeps below the loose flashing and causes major damage to the roof sheathing beneath the shingles.
