Restore and protect your roof with our expert cleaning and maintenance solutions
Get Free QuoteYour roof is one of the most critical components of your property, protecting it from the elements year-round. Over time, roofs accumulate moss, algae, lichen, and debris that can compromise their integrity and lifespan. Regular roof cleaning not only enhances your property's appearance but also prevents costly damage and extends your roof's life.
At Al Grey's Cleaning Services, we specialize in professional roof cleaning using safe, effective methods that remove harmful growth without damaging your roofing materials. Our team has over 13 years of experience working with all types of roofing, from traditional tiles and slates to modern composite materials.
We understand that a clean roof is more than just aesthetically pleasing—it's essential for maintaining your property's structural integrity and preventing issues like water penetration, rot, and insulation problems. Our comprehensive roof cleaning services are designed to protect your investment while enhancing your property's curb appeal.
Comprehensive solutions for all your roof maintenance needs
Our soft wash roof cleaning method is the safest and most effective approach for removing organic growth from your roof without causing damage. Unlike pressure washing which can force water under tiles and remove protective granules, soft washing uses low-pressure application of specialized cleaning solutions that break down moss, algae, and lichen at the root level.
The cleaning solutions we use are environmentally friendly and biodegradable, effectively killing organic growth while being safe for your plants, pets, and the surrounding environment. After application, the solutions continue working for weeks, preventing regrowth and keeping your roof cleaner for longer.
Low-pressure cleaning that protects your roofing materials from damage.
Biodegradable cleaners safe for plants, pets, and the environment.
Preventative treatments inhibit regrowth for extended periods.
Suitable for tiles, slates, metal, and composite roofing materials.
Soft washing is particularly effective for roofs with significant moss, algae, or lichen buildup. The process not only cleans the visible surface but penetrates to kill organisms at the root level, preventing rapid regrowth. We recommend soft wash cleaning every 2-3 years to maintain your roof's condition and appearance.
Moss and algae growth on roofs is not just an aesthetic issue—it can cause serious damage to your roofing materials. Moss retains moisture against the roof surface, leading to rot, degradation of roofing materials, and potential leaks. Algae stains, often appearing as black streaks, can also compromise the integrity of your roof over time.
Our specialized moss and algae removal service targets these growths effectively while protecting your roof. We use professional-grade treatments that kill existing growth and create an environment that discourages regrowth. For stubborn moss infestations, we may recommend mechanical removal followed by chemical treatment to ensure complete eradication.
Thorough removal of moss from all roof surfaces and valleys.
Specialized treatments to remove black algae stains and streaks.
Moss removal before winter prevents ice dam formation and damage.
Treatments to inhibit future moss and algae growth.
We pay special attention to roof valleys and areas where debris accumulates, as these are prime locations for moss growth. After removal, we apply zinc or copper-based treatments that slowly release ions when it rains, creating a surface that's inhospitable to future moss and algae growth. This preventative approach extends the time between cleanings and protects your roof investment.
Tile and slate roofs require specialized cleaning approaches to preserve their integrity and appearance. These traditional roofing materials can be delicate and require careful handling to avoid damage during the cleaning process. Our team has extensive experience working with all types of tile and slate roofs, from historic properties to modern installations.
We use gentle cleaning methods specifically designed for these materials, avoiding high-pressure techniques that can crack tiles or displace slates. Our approach focuses on removing biological growth and stains while preserving the protective surface of the tiles. For particularly delicate or historic roofs, we may recommend hand cleaning in specific areas to ensure no damage occurs.
Specialized low-pressure techniques that protect delicate materials.
Experience working with traditional and listed building roofs.
Cleaning methods that maintain protective coatings and glazes.
Comprehensive inspection for damaged or loose tiles during cleaning.
During the cleaning process, we conduct a thorough inspection of your tile or slate roof, noting any damaged, cracked, or displaced pieces that may need attention. We can provide recommendations for repairs or replacements if needed, helping you maintain a watertight and secure roof. Regular cleaning of tile and slate roofs not only preserves their appearance but can significantly extend their lifespan.
Our roof chemical treatments are designed to provide long-term protection against biological growth and staining. These treatments are applied after cleaning to create an environment that discourages moss, algae, and lichen from reestablishing on your roof surface. The treatments we use are specifically formulated for roofing materials and provide protection for extended periods.
We offer different types of chemical treatments based on your roof type and local conditions. Zinc-based treatments are excellent for most situations, slowly releasing zinc ions when it rains to inhibit growth. Copper-based treatments provide even longer protection but may not be suitable for all roof types. We'll recommend the best option for your specific situation during our assessment.
Chemicals specifically designed for different roofing materials.
Treatments that provide protection for 2-5 years depending on conditions.
Ion-releasing treatments that work each time it rains.
Low-impact treatments safe for surrounding vegetation.
Chemical treatments are particularly valuable in areas with high rainfall, abundant tree cover, or north-facing roofs that receive less sunlight—all conditions that promote biological growth on roofs. When combined with regular cleaning, these treatments can significantly extend the time between professional cleanings, saving you money while keeping your roof in optimal condition.

We use soft wash techniques that are specifically designed to be gentle on roofing materials while effectively removing biological growth. We avoid high-pressure washing which can damage tiles, remove protective granules, or force water underneath roofing materials.
Yes, moss can cause significant damage to your roof. It retains moisture against roofing materials, leading to rot and degradation. Moss can also lift tiles or slates, creating entry points for water. In winter, moss can contribute to ice dam formation. Regular cleaning prevents these issues and extends your roof's lifespan.
