Elastomeric Roof Coatings

An elastomeric coating is roofing applied in a viscous state. It has elastic properties, and can stretch in the summertime heat and then return to their original shape without damage.

Elastomeric coatings usually contain polymeric materials, such as acrylic, and a white pigment, such as titanium dioxide, to make them opaque and reflective. An elastomeric roof coating is applied thicker than paint.

Elastomeric coatings are very effective in solving roof leaks and can be used to restore virtually all types of roofs.

Types of Elastomeric Coatings

• Acrylic Elastomeric Coatings – This is most widely used roof coating. Acrylic elastomeric roof coatings may be used over properly sloped roof surfaces. The combination of longevity, easy clean up and environmental friendliness makes this coating the #1 choice of building owners and managers.
• Butyl Elastomeric Coatings – The preferred roof coating for flat roofs such as asphalt built up (BUR), modified bitumen (APP and SBS). It is highly resistant to ponding water.
• Polyurethane Elastomeric Coatings – Recommended for use on EPDM rubber roofs. It can also be used on modified bitumen and single ply roofing such as PVC and TPO.
• Silicone Elastomeric Coatings – A popular protective coating for polyurethane foam. Use on new installations or to recoat an existing silicone coated roof.

Water based or Solvent based?

Water based coatings are easy to use and clean up. They are usually permeable which allows moisture in the roof to escape. Solvent based coatings provide greater ponding water resistance and is commonly used over flat roofs.

Installation Options

The long term performance of elastomeric coatings largely depends on the attention to detail during the preparation and waterproofing stages. Elastomeric coatings are easy to apply. A small, simple roof can be successfully restored by the building owner with nothing more than a brush or roller. Large, complicated roofs best left to experienced roof coating contractors with specialized equipment.

Elastomeric Coating Process

Cleaning – Pressure wash the roof to thoroughly remove all dirt, dust, delaminating paints and coatings. A clean surface ensures good adhesion of our roof coating system.

Priming – Primers help create an ideal surface for our roof coatings. Special primers are available for difficult to adhere substrates and rusted metal roofs.

Waterproofing – All fasteners, seams, flashings and penetrations carefully sealed to prevent roof leaks. We have elastomeric caulks, seam tapes and special sealants to do the job right.

Topcoating – After all flaws and defects have been corrected, the elastomeric roof coating is applied by airless sprayer for a consistent finish. You can also use a brush or roller for small roofs.
