Roof Cleaning Cost Estimator

Roof cleaning in the Tulsa metro typically runs $0.30–$0.75 per square foot depending on roof type and method — about $600–$1,100 for a typical 2,000 sq ft asphalt shingle roof with soft washing. Metal roofs run slightly higher per square foot, and tile roofs the most. Use the estimator above for a custom range, then call Proof Construction at (918) 734-4444 for an exact free quote.

For asphalt shingles, soft washing is almost always the safer choice: low-pressure application with biodegradable cleaning solutions removes algae, moss, and black streaks without stripping granules. Pressure washing is best reserved for metal and concrete tile roofs where the surface can handle higher pressure. Proof Construction will recommend the right method for your roof type during your free inspection.

A moss and algae treatment add-on typically runs about $0.08–$0.15 per square foot, with a minimum around $150 — roughly $150–$300 extra on a typical home. It includes anti-moss rinses and inhibitors that keep growth from returning, which is worth it on shaded roofs or roofs near trees.

Most Tulsa-area roofs benefit from cleaning every 2–5 years. Roofs under heavy shade or near mature trees — where moss and algae thrive — may need attention every 1–2 years. Regular cleaning prevents moisture retention that can shorten shingle life and protects against wood rot in the decking below.

When done correctly with soft-wash methods, roof cleaning will not damage shingles or void most manufacturer warranties — in fact, GAF and other manufacturers recommend algae-resistant maintenance. High-pressure washing can strip granules and void warranties, which is why Proof Construction uses low-pressure, chemical-based cleaning on asphalt roofs.
