How much does roof coating cost per square foot?

Roof coating costs range from $1.50-$4.50 per square foot. Commercial-grade silicone coatings (GacoFlex, Progressive Materials) cost $2.50-$4.00 per square foot, while acrylic coatings (Henry, Western Colloid) average $1.50-$2.50. Most residential projects total $3,500-$7,000, while commercial projects range from $15,000-$50,000. Factors affecting price include roof condition, coating type, thickness, and preparation requirements. We offer volume discounts for properties over 10,000 square feet.

What types of roof coatings work best for Southern California's climate?

Silicone roof coatings perform best in Southern California due to superior UV resistance, waterproofing, and minimal degradation under constant sun exposure. High-solid silicone coatings (88%+) from GacoRoof and Karnak offer exceptional durability. Premium acrylic elastomeric coatings with high solar reflectance work well for budget applications but require more frequent reapplication. For metal roofs, we recommend aluminum-pigmented polyurethane systems. All our coatings meet California Title 24 compliance standards for energy efficiency.

How long do roof coatings last?

Premium silicone roof coatings typically last 15-20 years in Southern California, while acrylic coatings perform well for 7-10 years before requiring reapplication. Polyurethane coatings offer 10-15 year lifespans. Factors affecting longevity include coating thickness (we apply at 25-30 mils), roof traffic, maintenance, and initial surface preparation. Most manufacturer warranties range from 10-20 years, with our workmanship guarantee covering the first 5 years. Annual inspections extend coating lifespan significantly.

Can roof coating stop existing leaks?

No, roof coatings alone cannot reliably stop existing leaks. We first perform comprehensive leak detection using moisture meters and infrared scanning to identify and repair all water entry points before coating. For actively leaking areas, we use specialized repair materials like GacoFlex LiquidRoofing or Henry FlashMaster to create watertight seals at penetrations, seams, and damaged areas. Once repairs cure, the complete coating system creates a seamless membrane preventing future leaks.

Does roof coating reduce cooling costs in summer?

Yes, reflective roof coatings reduce summer cooling costs by 15-35% depending on building design, insulation, and previous roof condition. Energy Star-rated coatings with solar reflectance values above 0.85 reflect most solar radiation, preventing heat transfer. Commercial buildings often see payback periods of 3-5 years through energy savings. Southern California Edison offers rebate programs for qualifying cool roof installations. Interior temperature reductions of 10-15°F are common following application of high-reflectance coating systems.

Benefits of Professional Roof Coating

Applying a roof coating provides targeted protection against environmental damage, improves energy management inside the building, and lowers the costs related to roof upkeep. These advantages make roof coatings a practical upgrade for property owners focused on durability and cost efficiency.

Extending Roof Lifespan

A professionally applied roof coating serves as a protective barrier, defending your roof against damaging UV rays, water infiltration, and extreme temperature changes. These factors typically accelerate aging and cause premature roof failure.

By preventing moisture penetration, coatings help avoid leaks and reduce the risk of structural damage. Our use of high-quality silicone and acrylic-based coatings ensures excellent adhesion and flexibility, accommodating roof expansion and contraction without cracking.

This protective layer delays the need for costly replacements, often extending the service life of commercial and residential roofs by several years. We carefully select coating types compatible with existing roofing materials to maximize longevity and performance.

Improving Building Energy Efficiency

Roof coatings improve energy efficiency primarily through reflective properties that reduce solar heat absorption. This “cool roofing” effect lowers indoor temperatures in warm climates like Alhambra’s.

By reflecting a significant portion of sunlight, coatings reduce the workload on HVAC systems. This translates to measurable savings on energy bills over time.

We offer advanced white and reflective coatings, including elastomeric and polyurea options, tailored to different roof surfaces. These coatings are designed to increase thermal reflectivity and minimize heat transfer, supporting both comfort and sustainability goals.

Reducing Roof Maintenance Costs

Roof coatings decrease maintenance demands by providing a seamless, protective layer that guards against wear caused by weather and debris. This reduces routine repairs and prevents small issues from escalating.

Compared to a full roof replacement, applying a coating is a cost-effective solution that can be completed quickly, minimizing downtime for commercial properties.

Our expert team uses professional-grade materials and precise application techniques to ensure optimal coverage and durability. This approach translates into fewer call-backs and reduced long-term roofing expenses for our clients.

Bituminous coatings: Effective for asphalt and tar roofs, offering strong waterproofing.

Each material meets distinct performance criteria, and our experts help you choose the best fit based on your roof’s condition and intended benefits.

Weatherproofing and Energy Efficiency

Our roof coatings serve as barriers against moisture, wind, and temperature fluctuations. They seal vulnerable surfaces to prevent water infiltration and reduce thermal expansion damage. This protection minimizes wear and tear, lowering repair frequency.

Reflective coatings reduce heat absorption by up to 30%, which helps maintain cooler indoor temperatures. This decreases energy consumption for air conditioning and supports sustainability goals. We ensure proper surface prep and application to maximize these benefits and provide warranties covering product performance against weather challenges.
