A durable fix for a year-round roofing challenge

By Jesse Sanchez.

With spring storms on the way, commercial roofers may want to act now before repairs get urgent.

As spring arrives and commercial roofs across the country brace for volatile weather, building pros are looking for repair options that can withstand the unpredictable. CertainTeed®, a leading North American manufacturer of sustainable building materials, has introduced a product designed to do just that — 365 RepairMaster™, a ready-to-use silicone mastic offering year-round performance for tough roofing conditions.

Built for direct-bond permanent repairs, 365 RepairMaster™ tackles common roof issues from hail damage and foot traffic to fish mouths and surface cracks. It adheres to asphalt, single-ply, metal and most coatings — even when those surfaces are wet. That means contractors don’t have to wait for the perfect weather window to make critical fixes.

365 RepairMaster™ can even be installed under water, adding that additional pressure ensures bonding in such cases. That’s a notable edge when emergency repairs can’t wait.

The product doesn’t require a topcoat and resists UV damage, chalking and peeling when exposed to the elements — key for long-term performance. With high elasticity and recovery, it's also built to accommodate wide temperature swings and building movement.

Available in white, gray and black 2-gallon pails, the silicone mastic offers approximately 12-13 square feet of coverage per gallon at 1/8-inch thickness. It’s engineered for durability, with a tensile strength of 184 psi and elongation at 74%.

Despite its muscle, the mastic is simple to apply — no primer, no mixing and no special tools needed. And for those working within the CertainTeed SMARTCOAT™ system, it integrates seamlessly, including with the company’s restoration coatings and warranty offerings ranging from 10 to 20 years.

For contractors looking to stay ahead of seasonal wear and tear — or just avoid costly emergency calls down the line — 365 RepairMaster™ might be the tool that turns a reactive fix into a proactive win.
