Those dark streaks, black mold, and patches on your shingles aren’t just unsightly; they can shorten your roof’s lifespan and hurt your home’s curb appeal. The good news? Regular roof cleaning — including black mold roof cleaning — can restore your roof’s beauty, and in many cases, it could be free under manufacturer warranties.
Our lush landscapes, frequent rainfall, and high humidity create a paradise for black mold. This algae feeds on the limestone filler in shingles, creating dark streaks all across your roof.
At Daniel Hood Roofing, we use a soft wash method that applies low pressure techniques and manufacturer approved cleaning solutions to safely remove algae, black mold, and mildew. High pressure washing (often used in DIY attempts, especially for black mold roof cleaning) can strip granules from shingles, damaging your roof and voiding warranties. The Asphalt Roofing Manufacturers Association (ARMA) warns against such methods.
Our cleaning solutions not only eliminate existing algae but also inhibit regrowth, keeping your roof cleaner for longer. The process is safe for your shingles, your landscaping, and the environment, ensuring your home stays protected without collateral damage. A clean roof doesn’t just look great—it can extend the life of your shingles, improve energy efficiency and boost your home’s value.
If your roof is within the warranty period and shows any signs of algae, the manufacturer may cover the cost of a professional roof wash—or even a partial replacement in severe cases. Check your roofing contract or reach out to the company who installed your roof to confirm your warranty details.
If you’re unsure, Daniel Hood Roofing can help navigate the process- from verifying warranty coverage to coordinating with manufacturers. Don’t let this opportunity slip through your fingers, those free washes can save you hundreds of dollars!
Black mold doesn’t wait, and neither should you! The longer algae sits on your roof, the more damage it can cause. A clean roof also enhances your home’s curb appeal, which is crucial if you’re considering selling in this competitive housing market.
Don’t wait until the final whistle! Rising material costs mean now’s the time to tackle black mold before it turns into a costly repair blitz.
Regular roof washes are an investment in your home’s future. They’re quick (typically taking just a few hours) and the results are immediate. Don’t forget: if your roof is still under warranty, you might not have to pay a dime out of pocket. Roof outside your warranty period? Schedule a professional wash- it’s far more affordable than replacing damaged shingles or in some cases, replacing the entire roof.
At Daniel Hood Roofing, we’re more than just a roofing company—we’re your neighbors that are committed to serving East Tennessee with the same grit and heart that I brought to the Vols’ defensive line.
We take pride in helping homeowners maximize their warranties, so if your roof qualifies for a free wash, we’ll help guide you through the process! As a Knoxville native, I know how much your home means to you, and we’re here to protect it.
