Commercial Roofing Repair and Restoration
That Pays for Itself

If your building has an old, black tar or asphalt roof, Mast Roofing has an energy-efficient option to replacement. We use an Energy Star-rated white, reflective top coat which deflects the sun’s heat, providing you with immediate and long-term savings. These systems extend the life of your roof by shielding it from harmful UV rays, while reflecting 85 percent of the sun's energy to significantly lower the temperature of your roof by as much as 30-80 degrees.

Mod-Bit Roof Restoration and Coating by MAST Roofing

Mod Bit / Built Up Roof Coating Benefits include:

  • Coatings applied to your roof are impenetrable to water.
  • System can be renewed by recoating.
  • Your roof can remain in place usually making tear-off unnecessary and protecting your building against possible rain during construction.
  • All seams are reinforced to prevent leaks.
  • Efficient process and scheduling reduces or eliminates business interruptions.
  • Topcoat reduces adhesion of dirt minimizing maintenance.
  • Recoating option extends longevity of your roof for decades.

SUN-BLOCK for your roof = Significant Energy Savings

This is where your Return on Investment gets truly impressive! Coating your roof with reflective white achieves a "Cool Roof".  A Roofing System done by Mast Roofing reflects up to 85% of the sun’s energy away form the surface. A roof can reach up to 180⁰ F, but as shown above, our reflective coatings can lower that to almost ambient temperatures. This means that a huge amount of the heat is actually reflected away instead of passing through the roof into the interior, where air conditioning can be overtaxed and costly.
Studies have shown that building owners with white coatings have saved up to 40% or more in cooling costs. Savings so impressive that some customers have recouped their roofing system cost in only 7 years.

Featured Customer Review

I am writing this letter as a business recommendation for Mast Roofing Inc. Samuel and Paul Mast have just completed a 30,000 sq ft sealing of our roof at Minuteman Aviation. From start to finish they were hard working professionals that were a pleasure to work with. They were concise as to the work they were going to do for us and accomplished their work in a timeliness and quality of workmanship that is hard to find today. I would recommend them to any of my friends.
