About our Roof Washing in South Londonderry, PA
If your roof is covered in dark streaks, green moss, or stubborn algae growth, HydroPower Exterior Cleaning is ready to help. We serve South Londonderry and the surrounding Lebanon County communities with soft-wash roof cleaning that removes biological growth safely, without the high-pressure methods that can damage shingles or void manufacturer warranties.
Homeowners throughout Annville, Campbelltown, and Cleona trust us to restore the appearance and extend the life of their roofs. Those black streaks you see are typically caused by a hardy algae called Gloeocapsa magma, and left untreated, it spreads and degrades roofing materials over time. Our low-pressure soft-wash process applies professional-grade cleaning solutions that kill algae, moss, and lichen at the root, leaving your roof clean and protected.
We also serve Cornwall, Jonestown, Lebanon, and North Lebanon with the same attention to detail. Whether your home has asphalt shingles, metal roofing, or tile, our team arrives on time, uses the right technique for your roof type, and treats your property with genuine care from start to finish.
Residents in Mount Gretna, North Cornwall, and Lebanon South appreciate that we handle the entire job cleanly, protecting landscaping and surrounding surfaces during the process. No shortcuts, no guesswork, just thorough exterior cleaning done right.
HydroPower’s commitment is simple: Clean. Bright. Done Right. From Jackson to Myerstown, we bring the same professional standard to every roof washing appointment. Contact us today to schedule service in South Londonderry or any of the communities we proudly serve across the region.

Frequently Asked Questions
What is soft-wash roof cleaning and why does HydroPower use it in South Londonderry?▾
Soft washing uses low water pressure combined with professional cleaning solutions to safely remove algae, moss, and lichen from your roof. High-pressure washing can crack or dislodge shingles and may void roofing warranties. Our soft-wash method is the industry-recommended approach for residential roofs throughout South Londonderry and surrounding Lebanon County communities.
What causes the dark stains on roofs in the Lebanon and Annville area?▾
Those dark streaks are almost always caused by Gloeocapsa magma, a type of algae that thrives in humid conditions common to this region. Moss and lichen are also frequent culprits. All three can degrade roofing materials over time if left untreated. HydroPower's roof washing service eliminates these organisms and helps protect your roof's lifespan.
