Remove black algae streaks with a low-pressure cleaning plan selected for the roof material and condition.
Black streaks on many Florida asphalt-shingle roofs are algae discoloration. We first identify the roof material and check its condition, access, runoff, gutters and nearby landscaping. Moss, lichen, loose tile, brittle shingles or an active leak may need a different plan, or a roofer's opinion, before cleaning begins.
Asphalt shingles need a gentle method. Industry guidance calls for gently applying a manufacturer-appropriate cleaning solution and avoiding scrubbing or power washing that can loosen granules. We use low-pressure application and follow the applicable roof and product instructions for dwell time and rinsing. Tile and metal roofs are assessed separately because the material, coating, fasteners and condition change the right method.
We plan the work area before applying chemistry. That includes controlled application, landscaping pre-wetting and rinsing. Some dead growth releases gradually after treatment, and heavy moss or lichen may not disappear in one visit without risking the roof surface.
How long the result lasts depends on shade, tree cover, moisture and roof material. The written estimate states the method, included areas and any applicable spot-clean coverage.

"I couldn't be more impressed with the outstanding job Krystal Klean Exterior did on my house roof. Ben and his assistant were professional, efficient, and incredibly thorough from start to finish. They treated my home with care and delivered results that exceeded expectations. The roof looks fantastic, clean, refreshed, and better than ever."
"They did an amazing job went above and beyond to make sure that everything was nice clean and sparkling. I would definitely hire them again."
"Very pleased. They did a great job! The guys were really pleasant to work with...smiling and friendly. I will have them back."
"This was the second time we used Krystal Klean, the first was for pavers and this time was a tile roof softwash. Both services were excellent and the team members were super to work with. Last time we had our roof done, by another company, we had a ton of plant damage, this time the process that Krystal Klean used had no damage. We appreciate and recommend KK to anyone looking for these services."
"Justin and Chris did a phenomenal job cleaning my pool cage and roof after two hurricanes. I have not seen my pool cage this clean since we bought the house. They are very personable, detail oriented, have very competitive pricing and I will be using them regularly. Always glad to support a good local business. Highly recommended."
"Great company. Very polite and helpful workers that clearly knew what they were doing with excellent equipment. They did a fantastic job and made certain that we were totally satisfied with the job before leaving. I will definitely recommend them and seek them out next time I need to clean our tile roof."
