Closed cell roofing spray foam and coatings are good fit for flat or low sloped roofs. Depending on your roof, coatings alone may be a good option.
Roofing spray foam is a denser product than standard closed cell spray foam designed for interior application. It is designed to be walked on and resist damage from hail. Roofing foam is generally waterproof but requires a coating to protect it from UV damage. So, a coating is applied over top to protect it from UV damage and add an additional water proofing layer.
Elastomeric Coatings come in many different types: Silicone, Acrylic and Urethanes. We primarily use Silicone roof coating.
Cost Savings of Roof Coatings Over Traditional Repair Options
Reroofing with roofing spray foam and coating is a generally a lower cost option than conventional commercial roofing and can help the environment because you do not have to tear off and dispose of the roof in the landfill.
