Why Soft Washing? Because Your Roof Deserves Better

High-pressure washing strips protective granules, voids warranties, and forces water under your roof system. Our soft wash method kills growth at the root — safely.

❌ Pressure Washing Risks

• Strips protective granules from shingles
• Forces water under roofing system
• Voids manufacturer warranties
• Growth returns within months
• Can cause leaks and interior damage

✅ Our Soft Wash Method

• Low-pressure application — safe for all roofs
• Kills algae, moss, and lichen at the root
• Protects warranties and roof integrity
• Results last 2–3 years
• Prevents premature roof replacement

What We Remove From Your Roof

⚫

Black Streaks

Caused by Gloeocapsa magma bacteria. Feeds on limestone in shingles and spreads rapidly.

🌱

Moss

Lifts shingle edges, traps moisture underneath, and accelerates rot and structural damage.

🦠

Algae & Lichen

Eats into roofing material creating permanent pitting. Our treatment kills it completely.

💧

Moisture Damage

Organic growth retains water against your roof, causing decay, leaks, and mold inside.
