Project Overview
The customer, owner of a 15,000-square-foot EPDM and BUR combination roof, was searching for
a solution to extend the life of their roof without a full replacement. While the roof was in reasonably
good condition, the goal was to apply a long-term, cost-effective, and energy-saving solution before
any major degradation occurred.
After researching multiple options, the customer found only one product that checked all the boxes:
EPDM Coatings’ Liquid Butyl Rubber.
- No primer required
- One-coat application
- Solvent-based for deeper bonding
- Built-in mildewcide
- Exceptional solar reflectivity
The Application Process
The process began with a deep cleaning using our RoofProtect Cleaner, followed by reinforcing key
seams with SeamTight, embedding poly fabric for added durability.
- 52 (5-gallon) pails were used to cover the entire surface.
- The coating was applied using the roller method, sectioned into 15′ x 20′ zones.
- Each pail covered approximately 2.5 roofing squares, making it highly efficient.
The customer also compared our product to two other coatings on the market – one requiring a
primer, and the other requiring two topcoat applications. By choosing Liquid Butyl Rubber, they
saved approximately $26,000 on labor and materials.
The Thermal Impact: From 156F to 78F
What truly impressed the customer – and us – was the significant drop in roof surface temperature. Using a handheld infrared thermometer, they recorded the temperature of the black EPDM roof at a
scorching 156F before application. After applying the white Liquid Butyl Rubber coating, the
temperature dropped to 78F – a 50% reduction.
This drastic change is attributed to the coating’s high solar reflectance and thermal emissivity, which
helps keep buildings cooler and reduces energy consumption for air conditioning – especially during
peak summer months.
Why Liquid Butyl Rubber?
- Chemically fuses to the substrate for long-term durability.
- Prevents peeling, cracking, or flaking – even after years.
- Highly UV-resistant and designed to perform in extreme climates.
- A smart investment for both commercial and residential properties.
