Roof Cleaning
The Hidden Cost of a Dirty Roof
Those dark streaks running down your shingles are not just cosmetic. They are colonies of Gloeocapsa magma, a hardy blue-green algae that feeds on the limestone filler in asphalt shingles. Left alone, this organism spreads, holds moisture against the roof surface, and slowly degrades the granules that protect your shingles from ultraviolet light. On tile, slate, and metal roofs, moss and lichen do similar damage by trapping water in seams and lifting edges over time.
At Beatty Construction & Roofing, we treat roof cleaning as a maintenance service that extends the life of your investment, not simply a way to improve curb appeal. A clean roof reflects more sunlight, runs cooler, and lasts closer to its rated service life. As a family-owned and operated Class A licensed contractor serving Virginia Beach, VA, we approach every cleaning with the same care we bring to a full replacement.
Common Questions Homeowners Ask Us
The most frequent question we hear is whether pressure washing is safe for a roof. For most asphalt shingle systems, the answer is no. High-pressure water strips protective granules, voids many manufacturer warranties, and can force moisture under the shingle courses. This is why we rely on soft washing, a low-pressure method that uses controlled cleaning solutions to kill organic growth at the root rather than blasting it off the surface.
Another common concern is how long results last. When we apply the correct treatment, algae and moss stains typically stay away for several years, especially when paired with preventive measures. Homeowners also ask whether cleaning can hide existing damage. It cannot, and we would never present it that way. In fact, cleaning often reveals cracked flashing, loose fasteners, or storm damage hidden beneath the growth.
How We Clean Different Roof Systems
Every roofing material demands its own method, and our GAF Certified crews adjust the process accordingly. We never use one technique for every surface.
- Asphalt shingles: Soft wash application with a sodium hypochlorite blend that kills algae and lichen without disturbing the granule layer.
- Metal roofing: Gentle detergent wash to remove oxidation, dirt, and staining while protecting the factory finish and any protective coatings.
- Tile and slate: Careful low-pressure treatment that clears moss from the interlocks and edges without cracking brittle material.
Before any solution touches the roof, we protect landscaping, saturate surrounding plants with fresh water, and cover sensitive vegetation. After the treatment, we rinse and confirm that runoff paths and gutters are clear. This attention to the property around the roof is part of what it means to be Built on trust, backed by quality.
Storm Damage, Weather, and Why Timing Matters
Hampton Roads roofs take a beating from coastal humidity, hail, wind-driven rain, and the occasional snow event. Each of these conditions accelerates organic growth or drives debris into valleys and behind chimneys. Hail can bruise shingles and open microscopic paths for moisture, and once moss takes hold in those spots, deterioration speeds up quickly.
Because we handle roof repair and full roofing services in addition to cleaning, we can address problems the moment we spot them. If a cleaning inspection reveals wind-lifted shingles or damaged flashing after a storm, our team can repair the issue instead of leaving you to schedule another contractor. We also offer 24/7 emergency service, so if a storm damages your roof and water is entering the home, you can reach us at any hour.
The Preventive Approach We Recommend
Cleaning solves today’s problem. Prevention keeps it from returning. After a soft wash, we can install zinc or copper strips along the ridgeline. When rain passes over these metals, it releases trace ions that inhibit algae and moss growth on the courses below. Combined with proper gutter drainage and periodic inspection, this approach protects your roof for years.
We suggest a straightforward maintenance rhythm for most properties in our region:
- Annual visual inspection: We check for early streaking, debris buildup, and any storm-related damage.
- Cleaning every few years: Frequency depends on tree cover, shade, and humidity exposure at your property.
- Preventive metal strips: Installed once and effective for the long term against future growth.
