Pressure Washing Your Roof Can Destroy It
High-pressure washing blasts granules off asphalt shingles, forces water under tiles, and can strip protective coatings — voiding your roof warranty and shortening its life by years. It also doesn't kill algae; it just moves it around temporarily.
Soft washing is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA). Our biodegradable solution penetrates and kills algae, moss, lichen, and bacteria at the cellular level. Results last significantly longer — typically 2–5 years.
The Benefits of Professional Roof Cleaning
Kills Algae & Moss at the Root
Soft washing uses biodegradable solutions that kill algae, moss, lichen, and black streaks at the source — not just wash them away temporarily.
Extends Your Roof's Life
Algae and moss deteriorate shingles over time. Regular soft wash cleaning can add years to your roof's lifespan and prevent premature replacement.
Improves Curb Appeal Instantly
Black streaks and green growth dramatically age the look of your home. A professional soft wash restores your roof to a like-new appearance.
Protects Your Warranty
Many roofing manufacturers recommend low-pressure soft washing only. High-pressure washing can void warranties — our method keeps you covered.
Prevents Structural Damage
Moss and algae trap moisture against shingles and underlayment. Removing them prevents rot, leaks, and costly structural repairs.
Our Soft Wash Process
Roof Inspection
We assess the roof pitch, shingle type, level of algae/moss growth, and any areas needing special attention before we begin.
Solution Application
Our biodegradable soft wash solution is applied at low pressure to every affected area — killing algae, moss, and mildew at the root.
Dwell & Rinse
The solution is allowed to dwell, then gently rinsed at low pressure — safe for all shingle types including asphalt, tile, and metal.
Final Inspection
We walk the perimeter with you to confirm every section is clean, no solution remains on landscaping, and your property is left spotless.

Frequently Asked Questions
What is soft wash roof cleaning?
Soft washing uses low-pressure water combined with biodegradable cleaning solutions to safely remove algae, moss, lichen, and black streaks from your roof. Unlike pressure washing, soft washing won't damage shingles, void warranties, or force water under tiles.
Is soft washing safe for my shingles?
Yes. Soft washing is recommended by the Asphalt Roofing Manufacturers Association (ARMA) and most major roofing brands. High-pressure washing can strip granules from shingles and void warranties — our low-pressure method eliminates that risk entirely.
How long does roof cleaning take?
Most residential roofs take 2–4 hours depending on size, pitch, and level of growth. We'll give you an accurate time estimate after assessing your property.
How often should I have my roof cleaned?
In North Texas, we recommend roof cleaning every 1–3 years. Homes with mature trees or in shaded, humid areas may need more frequent service due to accelerated algae and moss growth.
Will the cleaning solution harm my plants or landscaping?
We pre-wet all plants and landscaping before applying the solution, and rinse thoroughly afterward. Our biodegradable formula is designed to be safe for surrounding greenery when applied correctly.
