At J Calvin Pressure Washing, we kick off roof washing with a thorough inspection across North Houston homes, from Spring to beyond. We assess black streaks, algae, moss, and lichen, ensuring our soft washing approach—unlike harsh pressure washing—protects your shingles while targeting grime effectively.
Next, we safeguard your property by pre-wetting plants and covering sensitive areas near the roof. Our biodegradable solution won’t harm your yard, but this step ensures no black streak-busting cleaner gets absorbed by leaves or grass, keeping everything safe as we prep for a deep clean.
Here’s the key—we apply our soft washing solution with low-pressure gear to lift algae, moss, and lichen gently. This method cleans thoroughly without damaging your roof, unlike pressure washing, ensuring those black streaks vanish while your shingles stay intact and protected.
Finally, we rinse with a light flow to reveal a spotless roof, washing away grime and solution residue. Our process slows regrowth of algae and moss, helping your roof resist degradation longer. With J Calvin, you get a clean that lasts—100% satisfaction guaranteed!
Roof size and condition matter, but most North Houston homes take 2-3 hours. Our team efficiently clears black streaks and algae in Tomball or Spring, so your roof looks great fast. Call 832-371-6030 for your estimate!
