Werner Commercial Roofing - Richmond's Expert Roofing Services

Those black streaks are actually a hardy algae called Gloeocapsa magma, which thrives in our humid climate. At Werner Commercial Roofing, our professional roof cleaning service uses specialized, low-pressure treatments to safely eliminate the algae without damaging your shingles. More than just cosmetic, this cleaning helps preserve your roof's lifespan and is often a recommended first step before a repair or reroofing project.

Roof valleys are critical drainage channels that handle a lot of water runoff, especially during Richmond's heavy rains. Leaks here are often due to worn flashing, improper installation, or debris buildup. Our detailed roof inspection will pinpoint the exact cause. Depending on the issue, our repair service may involve resealing, replacing the flashing, or, in cases of widespread wear, discussing a targeted roof replacement for the valley section to ensure a long-term, watertight solution.

This depends on the extent of the damage and the overall condition of your roof. A repair is often sufficient for isolated flashing failures. However, if the leak has caused significant deck rot, compromised multiple shingles, or if the roof is nearing the end of its lifespan, a partial or full roof replacement becomes the more reliable and cost-effective choice. During our inspection, we'll provide a clear, honest assessment and explain all your options, from repair to reroofing, to protect your Richmond commercial property.
