Roof Coatings and Restoration

We restore aging roofs with silicone and elastomeric coatings that add 10 to 20 years of reliable protection. These coatings reflect up to 90 percent of sunlight and reduce heat buildup that strains HVAC systems.

Our clients report consistently leak-free performance because BUR systems deliver proven strength and durability.

PVC Polyvinyl Chloride Roofing

We install PVC roofing that delivers chemical resistance, energy efficiency, and long-term reliability for 25 to 35 years.
