You glance up from the driveway and notice dark stripes running down your shingles like someone spilled ink. Those aren’t just ugly, they’re algae, moss, and mold feeding on the limestone in your shingles and shaving years off the roof’s life. Roof Repair Experts, based in Delaware, offers honest, local roof cleaning services that safely remove grime and make your roof look new again, without the damage caused by pressure washing.
Why Local Gutter and Roof Cleaning Service Matters in Delaware
Salt air, oak pollen, and humid summers turn Delaware roofs into buffet tables for algae (Gloeocapsa magma) and moss. The black streaks trap heat, raise cooling bills, and hold moisture that rots shingles from the inside out. In beach towns like Rehoboth and Lewes, the problem is exacerbated by constant humidity and sea spray.
Clean gutters matter just as much. Clogged gutters, when soaked, can weigh hundreds of pounds and pull away from the house, dumping water against the siding and foundations. One local gutter and roof cleaning service visit fixes both problems the same day.
What Our Local Roof Cleaning Service Actually Does
We use the ARMA-recommended soft-wash method, which involves a low-pressure rinse (approximately the force of a garden hose) combined with a biodegradable, algae-killing solution approved by GAF and CertainTeed. No high-pressure blasting that uses grenade-like granules; this method voids warranties.
The treatment kills algae at the root. Streaks fade in 2–6 weeks as rain rinses dead growth away. Moss gets lifted by hand, then treated so it never returns. Gutters are flushed, downspouts checked, and debris bagged; no piles left in your yard.
Most Delaware homes finish in 3–5 hours.

Common Roof Cleaning Mistakes Delaware Homeowners Make
Every spring, we get panic calls from homeowners who tried DIY or hired the wrong crew. Here are the four biggest mistakes we see across Delaware, and why they end up costing more than professional local roof cleaning service ever would.
First
The pressure-washer rental from the big-box store. Guys crank it to 3,000–4,000 psi because “it works faster.” In reality, that blasts granules off architectural shingles in minutes, shortens roof life by 5–10 years, and voids every manufacturer’s warranty. We’ve replaced entire roofs in Middletown and Smyrna that were only 8–10 years old because someone “saved” $300 with a rented wand.
Second
Straight bleach from the laundry aisle. It kills algae instantly and looks amazing the same day, but bleach eats asphalt, corrodes aluminum flashing, and kills every plant below. Within a year, the roof appears worse than before, and the gutters have turned white with corrosion. Our plant-safe, sodium-hypochlorite-based mix is buffered so it only attacks algae, not your roof or landscaping.
Third
Climbing the roof without safety gear. Falls from one-story roofs send dozens of Delaware residents to the ER every year. One slip on wet moss can mean a broken hip and $40,000 in medical bills. Our crews use harnesses, roof brackets, and $2 million in liability insurance, so you never have to take that risk.
Fourth
Ignoring the gutters until they overflow. Many “roof cleaners” only spray shingles and leave the gutters packed with wet leaves and shingle grit. That defeats the entire purpose; water still backs up under the shingles the next time it rains. We always flush and inspect every foot of gutter and every downspout at no extra charge when you book the full local gutter and roof cleaning service.
The average DIY project gone wrong costs $2,500–$8,000 to fix, compared to what should have been a $500–$700 professional job. One call to +1 (866) 240-4037 or email to info@roofrepairexperts.com prevents all of it. We clean it right the first time, protect your warranty, and keep you safely on the ground.
