Commercial Roof Restoration

The building roof restoration process extends the roof’s lifespan for commercial or industrial buildings with low slope single ply or steep slope metal roof systems. Generally speaking, the process can be described as adding a liquid coating to the roof. The coating system fully encapsulates the roof surfaces with a seamless, reflective, and watertight membrane.

While commercial roof restorations may not be suitable for every situation, there are undoubtedly many benefits to restoration compared with a complete roof replacement. Here are some of those benefits to consider.

Less expensive than a full roof replacement
Restoration provides many of the advantages of a new roof but at a fraction of the cost. This process requires less labor because the existing roof is not removed. And although there is a cost for the roof coating, it tends to be less than paying for new insulation, cover boards, membrane, and accessories.

Extends the life of your commercial roofing systems
The average commercial roof has a lifespan of between 15-20 years, but a restoration project may add up to a decade of life to your roof –as long as you hire a company that delivers quality workmanship and the coating is given proper maintenance. In some situations, the restored roof can be recoated, which means you can further put of complete replacement.

Provides a highly effective roof surface
The restoration system added to your roof’s surface will provide a protective watertight membrane that can stop leaks and reduce the need for roof repairs. That is music to the ears of many building owners.

Restoration projects can reduce your energy bills. Roofing systems tend to provide solar reflectivity and emissive qualities that can improve the energy efficiency of your building.

Not only should your energy costs be lower, but the roof restoration may also extend the life of your HVAC equipment because the highly reflective surface reduces the heat in the building.

Roof restorations are environmentally friendlier than a full tear-off
Re-roofing requires all the existing roofing materials to be torn off, which creates a great deal of landfill waste. However, since this roof system extends the service life of your roof, it will be years before the debris from a full replacement needs to be added to the landfill.

Commercial Roof Maintenance

For all low-slope/flat roof types, long-term standing water can cause excessive weathering, allowing your roof membrane to become brittle. Signs of long-term standing water are mold and vegetation growth. We check the underside of the roof and your drop ceiling to see if there are any signs of water damage, which is a sign of damage to your roof cover system.

Ballasted roof system: We inspect for uneven distribution of rocks. If there are bare spots, we move the rocks back evenly into place, covering all exposed roof membrane. 

Built-up and modified bitumen: DunRite checks the cover for bubbles/blisters, cracks, excessive wear around connections, tears, punctures, and excessive weathering resulting in loss of embedded gravel or smooth surface protective coatings for built–up roofs.
   
Single-ply: Inspect and repair tears, worn seams, seam failure, gaps, fasteners backing out, punctures, and brittleness. For adhered or glued-down systems, inspect for excessively loose membranes and blisters. 
 
Sprayed polyurethane foam:  DunRite checks for excessive weathering, tears, or punctures, which causes a loss of the acrylic coating. 
  
Metal panels: Inspect for loose screws and deteriorated rubber washers, which can wear down over time. Inspect for discolored or worn off paint, which acts as an anti-rust layer, and for signs of rusting. Additionally, we look for dents or divots.  

Asphalt shingles: Inspect for curling, loose, and/or torn shingles.
