Roof Waterproofing

Belzona products can repair and restore roofs using roof waterproofing materials. They can seal leaks and protect from weather conditions.

Roof integrity can often be jeopardized by various factors such as movement during freeze-thaw cycles, physical damage, rain, and adverse weather conditions. These effects can prove highly detrimental and damaging to the roof’s waterproofing capabilities. Other areas susceptible to damage include joints and seams, flashings, gutters, and glazing bars as these are areas in which water can easily accumulate. Liquid-applied waterproofing coatings offer an alternative solution to traditional roof repair methods. They will water and weatherproof the roof, simplify roofing maintenance, provide long-term protection, bond strongly to all types of roofing substrate, follow complex roof contours, and avoid hot work and odor issues.

Typical Application

  • Creation of waterproof and weatherproof roof surfaces
  • Weatherproofing around upstands and other roof protrusions such as skylights, chimneys, and vents
  • Long-term roof leak repair and protection of deteriorated gutters
  • Replacement of damaged or missing flashings
  • Protection of insulation on pipes, air-conditioning ducting, valve boxes, flange covers, boilers, pressure vessels, bulk storage tanks, and heat exchangers
  • Long-term lagging protection on new and existing steam, condensate, or chilled pipelines
  • Seamless encapsulation of elbows, T-pieces flanges, and complex contours
  • Sealing of gaps and joints on coping stones as well as roof parapet walls
  • Sealing of glazing bars
  • Tank base sealing

Questions & Answers

The application of a rooftop waterproofing system depends on the product. Generally, a stiff-bristled brush or the plastic applicator provided can be used to apply coatings. A Belzona product can be applied using a spray gun in some instances.

The cure time of a roof waterproofing material depends on the product. Please refer to the documentation of the product you are using for more information. As an example, Belzona 3111 cures in 2-6 hours. For more information on Belzona 3111, please see the Instruction for Use (IFU)

Roof waterproofing coatings work by creating a barrier that excludes moisture and the natural elements, potentially leading to corrosion, wear, and other problems. In addition, the coatings are microporous, which allows the substrate to breathe, therefore, letting trapped moisture escape.
