What is Roof Restoration?
Roof restoration, also known as liquid roofing, involves revitalizing your existing roof using elastomeric roof coatings. Unlike replacement, this process typically doesn't necessitate removing or replacing existing materials, except for damaged sections.
The coatings used in commercial roof restoration systems create a seamless, flexible, reflective, and waterproof membrane that fully encapsulates roof surfaces.
Various roof coating chemistries are available, including acrylic, butyl, silicone, and urethane, suitable for different commercial roofing substrates such as metal, modified bitumen, built-up roofs, PVC, TPO, EPDM, concrete, and spray polyurethane foam.
Benefits of Roof Restoration
1. Cost-Effectiveness
Roof restoration offers the benefits of a new roof at a fraction of the cost. Compared to the labor and materials involved in a full replacement, restoration typically costs 50-70% less.
2. Extended Service Life
Restoration systems can significantly extend the lifespan of commercial roofs. With proper installation and maintenance, they can add 10, 15, or even 20 years to the roof's serviceable life, sparing you from premature replacement.
3. Enhanced Performance
Restoration coatings adhere effectively to commercial roof surfaces, providing a protective, seamless membrane that prevents leaks and renews performance. This reduces the need for frequent maintenance and repairs.
4. Energy Efficiency
Roof restoration systems boast excellent reflective and emissive properties, improving the energy efficiency of facilities. By reflecting a significant portion of the sun's UV radiation and reducing heat transfer, they can lower HVAC workload and cooling costs by up to 20%.
5. Sustainability
With growing concerns about environmental impact, the demand for sustainable roofing solutions has surged. Unlike roof replacement, restoration generates minimal waste and doesn't require tear-off, making it a more eco-friendly option.
6. Minimal Disruption
Compared to roof replacement, restoration is less disruptive to building occupants and can be installed much faster, minimizing interruptions to day-to-day business operations.
When to Consider Roof Restoration
Ideally, roof restoration should be considered proactively, before significant issues arise. The earlier it's implemented, the better its long-term performance. However, the roofing assembly must be structurally sound and free of wet or saturated insulation.
For metal roofs, some rust and corrosion are acceptable as long as it doesn't compromise structural integrity. Ultimately, a thorough assessment and adhesion test patch are recommended to determine the suitability of a roof for restoration.
By considering these factors and leveraging the benefits of roof restoration, commercial property owners and facility managers can prolong the lifespan of their roofs and enjoy cost savings and environmental benefits in the process.
