The cost of roof cleaning depends on several factors, including the size of the roof, roof pitch, accessibility, roofing material, and the amount of algae, moss, or organic growth present.Most residential roof-cleaning projects are priced based on the individual property rather than using a one-size-fits-all price. A smaller, easily accessible roof with light algae growth will generally cost less than a large or steep roof with significant buildup.At Anchor Roof Restoration & Cleaning, we provide transparent, property-specific estimates so you know what you're paying for before the work begins.

For most asphalt shingle roofs, soft washing is the preferred cleaning method. Soft washing uses low water pressure combined with a cleaning solution designed to break down algae, mold, mildew, and other organic growth.Unlike high-pressure cleaning, soft washing does not rely on force to remove buildup from the shingles. This makes it a safer approach for many residential roofing materials.

High-pressure washing is generally not recommended for asphalt shingles. The force of high-pressure water can potentially damage the shingles, remove protective granules, and shorten the useful life of the roofing material.At Anchor Roof Restoration, we use appropriate low-pressure cleaning methods for roofs rather than aggressively blasting shingles with high-pressure water.

When performed correctly using an appropriate cleaning method, roof cleaning should not damage properly installed roofing materials.The biggest concern is using excessive pressure or an inappropriate cleaning method. That's why we use low-pressure techniques designed specifically for roof cleaning.We also take precautions around landscaping, siding, windows, and other areas of your property during the cleaning process.

Yes. The black streaks commonly seen on asphalt shingles are often caused by algae growth, which can be particularly noticeable in humid environments like Wilmington, NC.A proper roof-cleaning treatment can significantly reduce or remove this discoloration and restore a cleaner appearance to the roof. The final result can vary depending on the severity and age of the staining.

No. Roof cleaning itself does not extend the life of your roof. Roof cleaning is primarily intended to remove algae, moss, dirt, and organic buildup and improve the appearance of your roof. While regular cleaning can help maintain your roof, it does not restore the roofing material or reverse the effects of aging.Roof rejuvenation, however, is specifically designed to help extend the service life of certain aging asphalt-shingle roofs. Rejuvenation treatments replenish oils that can be lost as shingles age, helping restore flexibility and improve the overall condition and appearance of the shingles.If your roof is aging but still structurally sound, roof rejuvenation may be a cost-effective alternative to premature replacement. We can evaluate your roof and help determine whether cleaning, rejuvenation, or replacement makes the most sense for your property.

Yes. Roof cleaning and roof rejuvenation are two different services.Roof cleaning focuses on removing algae, dirt, moss, and other organic buildup from the surface. Roof rejuvenation is intended for certain aging asphalt-shingle roofs and focuses on conditioning the shingles to help restore flexibility and improve their appearance.If your roof is showing signs of age but isn't ready for replacement, roof rejuvenation may be an option worth considering.
