How We Clean Without Damage

First, we inspect your roof and identify what type of growth you’re dealing with. Algae, moss, and lichen all require different approaches.

We apply our cleaning solution using low-pressure methods that won’t damage your shingles or void your warranty. No high-pressure washing that strips away protective granules.

The solution does the work, not the pressure. Algae disappears quickly, while moss and lichen may take time to loosen and fall away naturally. We protect your landscaping throughout the process and clean up completely when finished.

What's Included in Professional Cleaning

You get a thorough inspection to identify all problem areas, not just the obvious black streaks. We treat algae, moss, lichen, and mildew using manufacturer-approved methods that protect your warranty.

McGaheysville’s humid climate creates perfect conditions for roof growth. The Shenandoah Valley’s mix of shade from surrounding mountains and seasonal moisture means roofs here need regular attention to prevent damage.

We protect your gutters, landscaping, and outdoor furniture during the process. You receive clear communication about what we found and what we treated, plus guidance on preventing future growth.

Will roof cleaning damage my shingles or void my warranty?

Professional roof cleaning using approved methods actually protects your warranty. Shingle manufacturers like GAF and CertainTEED specifically recommend low-pressure chemical cleaning to remove algae and moss. High-pressure washing is what damages shingles and voids warranties. It strips away protective granules and can force water under shingles. We use only manufacturer-approved soft wash methods that rely on chemistry, not pressure. The cleaning solution does the work safely. Algae disappears on contact, while moss and lichen loosen over time and fall away naturally with rain and weather.

How often should I have my roof cleaned in McGaheysville?

Most McGaheysville roofs need cleaning every 2-3 years due to the area’s humid climate and seasonal conditions. The Shenandoah Valley’s moisture and shade create ideal conditions for algae and moss growth. If you see black streaks starting to appear, don’t wait. Early treatment is easier and less expensive than dealing with heavy growth that’s had time to damage shingles. North-facing roof sections typically need attention first since they stay damp longer and receive less direct sunlight. Regular cleaning prevents the growth from taking hold and causing real damage.

What's the difference between algae, moss, and lichen on my roof?

Algae appears as black or dark gray streaks that run down your roof. It’s the most common problem and relatively easy to remove, though it will spread and get worse if left untreated. Moss looks like a green carpet and grows upright, usually under tree shade. It’s more serious because it can lift shingle edges and cause blow-offs during storms. Lichen appears as round, raised green spots that dig into shingle granules. Each requires different treatment approaches and timing. Algae cleans off quickly, while moss and lichen need time to die and fall away naturally after treatment.

Is roof cleaning worth the cost compared to replacement?

Professional roof cleaning costs a fraction of replacement and can extend your roof’s life by years. Many roofs get replaced unnecessarily just because they look bad, not because they’re actually failing. Algae and moss don’t just look bad – they cause real damage. Algae makes your roof absorb more heat, increasing cooling costs. Moss can lift shingles and cause leaks. Both feed on your shingles and shorten their lifespan. Cleaning removes the growth before it causes structural problems. You avoid premature replacement, maintain your home’s value, and eliminate a major selling objection if you decide to move.

Can I clean my roof myself with store-bought products?

DIY roof cleaning is risky and often ineffective. Walking on roofs is dangerous, and using the wrong pressure or chemicals can damage shingles or void warranties. Store-bought products rarely have the strength needed for established growth, and applying them safely requires professional equipment and knowledge. Many homeowners end up causing more damage than the original problem. Professional cleaning uses commercial-grade solutions applied with proper equipment and safety measures. The cost difference isn’t worth the risk of injury, damage, or having to do the job twice.

Will cleaning remove all the stains, or will some remain?

Most algae stains disappear immediately during treatment. You’ll see dramatic results right away as the black streaks vanish. Moss and lichen take longer because they have root systems that need time to die and fall away. Some staining may remain where heavy growth has been present for years, but the growth itself will be eliminated. The goal is stopping the damage and preventing regrowth, not necessarily making an old roof look brand new. Professional cleaning focuses on protecting your investment and extending your roof’s functional life.
