Asphalt roof has dark patches

If your asphalt roof has black streaks, or dark patches on it, this can be caused by algae. Algae prefers damp, humid climates and will grow easily on any type of roof. Algae is simply a cosmetic issue and does not affect the integrity of your roofing material. However, if you want to remove it from your home’s exterior walls and prevent its return in future years, a professional can apply a cleaning solution that will eliminate algae growth without harming the existing surface or causing damage to plants nearby.

Missing granules

Missing granules are a sign that your roof may be in need of repair or replacement. Granules help prevent shingles from becoming damaged by exposure to the sun, and missing granules can be caused by poor quality shingles, age or exposure to the elements. If your roof is more than 10 years old, it’s time for an inspection!

Cracking shingles

Cracked shingles can be a sign of damage, so if you see them, it’s important to check with a roofer. If the cracks are small and not too far apart, they may just require some repair. However, if there is damage to the underlying sheet metal or flashing that causes leaks in your roof system, this will need to be repaired before new shingles can be installed.

If you notice cracked or missing shingles on your roof and want to know whether or not it’s time for repairs or replacement of your entire roof system (roof), contact us today!

Shingles are buckling, curling or blistering

If your shingles are buckled, curled or blistering, they may be damaged by moisture getting trapped underneath the shingle. If you have any of these issues, it’s best to contact a professional right away because the problem could worsen over time. The longer you wait to get it repaired, the more damage will happen.

Shingles can also become damaged if roofing nails are too long for their location on your roof or if your contractor doesn’t use enough adhesive when nailing down new shingles. Either way, these issues will cause water damage underneath your shingle and make them less effective at keeping out rainwater and other elements that could cause leaks in your home

Roof valleys with shingle grit

Roof valleys are the areas where two sloped roofs meet. They can be the most difficult areas of your home’s roof to repair, as they are often small and not easily accessible by ladder.

There are several different issues that cause roof valleys to wear out:

  • Leaves and debris build up in these areas over time, which can increase wind resistance and lead to more frequent damage in an area that is already weak because of poor drainage or poor construction.
  • Poorly installed shingles can lead to buckles along these edges when water runs down them during rainstorms.
  • Construction materials such as nails or staples may have been used instead of proper fasteners like screws or rivets in this area, leading them to loosen over time due to weather conditions and repeated stress from heavy winds blowing against them.
