Common questions
How often should I get my roof cleaned in Washington D.C.?
Given the humid climate in Washington D.C., annual roof cleaning is often beneficial. This helps prevent the buildup of algae and mildew, which can thrive in the local weather conditions. Regular cleaning maintains your roof's aesthetic appeal and structural integrity.
What is the 25% rule for roofing?
The 25% rule in roofing is a guideline suggesting that if more than 25% of a roof deck requires repair or replacement, it is typically more cost-effective and practical to replace the entire roof. This ensures a uniform surface and prevents future issues.
What causes algae on roofs in D.C.?
Algae growth on roofs in Washington D.C. is primarily caused by moisture and shade. The humid summers and periods of rainfall provide the ideal conditions for algae to colonize shingle surfaces, leading to the characteristic dark or greenish streaks often seen.
How much does it cost to have a roof cleaned?
The cost of roof cleaning depends on the roof's size, the type of material, and the extent of algae or mildew growth. Roof pitch and accessibility can also influence the final quote. We offer free phone consultations to provide an accurate estimate for your property.
