What Is Roof Coating?

Roof coating is a liquid-applied membrane that forms a thick protective layer over the existing roof surface. It’s designed to extend the lifespan of the roof by shielding it from harmful UV rays, moisture, and other environmental elements. Roof coatings provide a seamless, monolithic barrier bridging minor cracks and seams, preventing water infiltration and potential leaks.

Roof coatings can be applied to many roofing materials, including:

• Metal
• Single-ply membranes
• Modified bitumen
• Built-up roofing systems

If you have a different roofing system and would like to have it coated, it's best to consult our professionals.

How Long Does Roof Coating Last?

The general lifespan of a roof coating depends on several factors, such as the quality of the product, the thickness of the application, and the level of maintenance performed. On average, most roof coatings can last between 5 to 10 years, with some high-performance coatings lasting up to 20 years or more.

However, regular inspections and timely recoating can significantly extend the coating’s service life, ensuring long-term protection for the underlying roof system.

Types of Roof Coating

There are several types of roof coating products available in the market, each with its unique properties and advantages.

Acrylic Coatings

Acrylic coatings are among the most popular and cost-effective options, offering excellent UV resistance and flexibility.

Silicone Coatings

Silicone coatings are known for their superior weathering capabilities and long-term durability.

Polyurethane Coatings

Polyurethane coatings provide exceptional strength and chemical resistance, making them suitable for harsh environments.

Aluminum Coatings

Aluminum coatings offer excellent reflectivity, helping to reduce energy costs by reflecting solar radiation.

The best way to know which product will work best for your roof is to consult one of our expert roofers. They’ll conduct an examination, consider the roofing material and its condition, and recommend a coating that will yield the best results.

What’s the Cost of Roof Coating?

There is no set price for roof coating. The total cost hinges on several factors, such as the size of the roof, the type of coating selected, and the complexity of the project.

In general, roof coatings are considered a cost-effective solution compared to complete roof replacement, though they do require an investment. The cost typically ranges depending on the quality of the product and the labour needed. However, the long-term benefits of roof coatings, including extended roof life and potential energy savings, often outweigh the initial investment.

What’s the Best Temperature to Apply Roof Coating?

The ideal temperature range for applying roof coatings varies depending on the specific product and manufacturer’s recommendations. Generally, most roof coatings should be applied when ambient and surface temperatures are between 10°C and 32°C. Applying coatings outside of this temperature range can affect their curing process and overall performance. It’s essential to follow the manufacturer’s guidelines and consult with a professional roofer to ensure proper application and optimal results.

When you partner with us, we’ll inspect your roof and recommend the best time to conduct a roof coating project.

ASTEC Re-Ply fluid-applied roof systems can be installed directly over most traditional roof substrates. Tear-off, land-fill fees, reconstruction, and long facility disruptions are eliminated.

A fluid-applied roof is a multi-layered system that creates a seamless waterproof seal over an existing, qualified, substrate; eliminating the need for costly roofing tear-off and replacement. Many roofs that are being torn off would qualify as substrates for conversion to sustainable, fluid-applied roofs, resulting in huge savings with the elimination of unnecessary expenses in facility downtime, reconstruction and disposal costs. Don’t let your roof waste your maintenance budget. Never pay to replace a roof you can convert to a sustainable (renewable) watertight roof.

The ASTEC fluid-applied re-roofing system has been installed on millions of square feet. It cures current problems as well as prevents future problems. The system stops water leaks, waterproofs and eliminates roof movement or thermal shock, the leading cause of roof leaks. Under roof temperatures are up to 25% cooler in the summer. The ASTEC system prevents corrosion, eliminates rust and deadens sound.
