What Are the Benefits of Commercial Roof Coatings?

Commercial roof coatings offer a cost-effective way to protect your property and reduce operational expenses. These coatings form a seamless membrane that seals leaks, reflects heat, and resists environmental damage.

Key advantages include:

  • Stopping active leaks and preventing future water intrusion
  • Reducing cooling costs with UV-reflective surfaces
  • Avoiding expensive tear-off and replacement
  • Adding 10 to 15 years of life with renewable warranties
  • Suitable for food-grade, high-temp, and interior/exterior use
  • Protecting against rust, corrosion, and weathering

Where Can Roof Coatings Be Used on Commercial Buildings?

Not all roofs are suitable candidates for coatings, but many flat or low-slope systems can significantly benefit from this protective solution.

Here are the most common roof types suitable for coatings:

  • EPDM (rubber) roofing
  • TPO and PVC roofing
  • Modified bitumen roofs
  • Metal roofs
  • Concrete or spray foam roofs

Why Might a Roof Be Unsuitable for Coating?

Some roofs may not be good candidates for a coating if they have serious damage that can't be repaired, such as large cracks, extensive leaks, or if the underlying structure is too weak to support the added weight. Roofs with standing water due to a lack of proper slope also won't work for coatings since water buildup can lead to further issues.

Before deciding on a coating, it's important to have a thorough inspection to make sure the roof's surface is dry, the deck is strong, and the materials underneath are in good shape to support the coating system.

Can You Recoat Over an Existing Roof Coating?

Recoating over an existing roof coating is possible, as long as the current coating is still firmly attached and the roof is in good condition. Before applying a new layer, it's important to inspect the surface to make sure there are no major issues, like peeling, cracks, or extensive damage. If everything checks out, applying a fresh coat can extend the life of your roof, enhance its protection, and save you time and money compared to a full replacement.

What Preparation Is Required Before Applying a Commercial Roof Coating?

Proper roof surface preparation is critical to ensure coating adhesion, performance, and longevity.

Here's what's involved in the preparation process:

  • Thorough cleaning: Power washing to remove dirt, debris, oils, and algae
  • Moisture testing: Ensuring the roof is dry and free of trapped water or saturated insulation
  • Repairing seams and penetrations: Patching cracks, sealing joints, and reinforcing flashings
  • Crack and blister correction: Removing loose material and applying patching compound as needed
  • Detail work around HVAC, drains, and vents: Ensuring all rooftop equipment areas are properly sealed

Skipping or rushing these steps can lead to coating failure.

What Is the Role of a Primer in Roof Coating Systems?

Primers play an important role in getting your roof ready for a coating. They help the coating adhere better, especially on older roofs or materials like metal and EPDM, which can be more challenging to bond with. Primers can also prevent rust from spreading, remove contaminants, and fill small gaps or pores on the surface. While not every roof coating project requires a primer, using one can significantly enhance the coating's longevity and performance over time.

How Long Does a Commercial Roof Coating Application Take?

The length of a commercial roof coating project depends on the size and condition of the roof, but most jobs fall within a 1- to 12-week range. We aim to respond within one business day and provide free estimates within a few days of inspection. Whether your project is urgent or scheduled in advance, we’ll align our timeline with your needs.

How Long Does It Take for Roof Coating To Cure?

A commercial roof coating takes anywhere from 24 to 72 hours to fully cure. At this point, it will have completely hardened and reached its maximum durability. However, the initial drying time can be much faster, often within just 1 to 6 hours. Cooler temperatures or high humidity can slow down the drying and curing process, so it’s important to plan accordingly and allow enough time for the coating to set properly before exposing it to heavy use or harsh conditions.

What’s the Cost of Commercial Roof Coating Service?

The cost of a commercial roof coating varies based on factors like roof size, condition, and the type of coating system used. We provide free, no-obligation quotes to help you understand your options and budget accurately. Reach out to schedule an inspection and get a tailored estimate.
