Those dark streaks or patches on your roof may be more than just dirt. It could be mold, algae, or mildew growing on your shingles. Left untreated, this growth can trap moisture, weaken roofing materials, and shorten the lifespan of your roof.
Leaves and other debris built up can collect in valleys and low spots on your roof and hold moisture against your shingles long after the sun has dried out the surface.
If you've noticed discoloration or signs of mold on your roof, let our team take a look. We'll assess the condition of your roof and recommend the best solution to protect your home.
