Roof Restoration
When it comes to extending the life of an existing roof, few solutions can match the efficiency and effectiveness of fluid-applied silicone roofing systems. This innovative roofing technology is an excellent choice for revitalizing TPO, PVC, or EPDM roofs, providing a seamless, durable barrier against the elements.
What is Fluid-Applied Silicone Roofing?
Fluid-applied silicone roofing involves the application of a liquid silicone coating directly onto an existing roof surface. This coating cures to form a rubber-like elastomeric membrane that is waterproof and highly resistant to weathering, ultraviolet light, and temperature extremes. It’s a cost-effective solution that can significantly extend the life of your roof without the need for a complete replacement.
Why Choose Silicone Over TPO, PVC, or EPDM?
Enhanced Durability
Silicone coatings are known for their exceptional durability. Unlike traditional roofing materials that can degrade over time due to exposure to the elements, silicone maintains its integrity and flexibility, resisting cracking, peeling, or blistering.
Superior Weather Resistance
The seamless nature of a silicone roof coating eliminates many of the vulnerabilities found in other roofing systems, such as seams and joints, which are common points of failure in TPO, PVC, or EPDM roofs. This seamless coverage provides superior protection against water penetration and leaks.
Cost-Effective Maintenance
Maintaining a silicone-coated roof is generally less costly and less labor-intensive than traditional roof repairs. The ease of application and the ability to recoat existing systems without stripping the old material also make it a more sustainable and cost-effective option.
Extended Roof Life
Applying a silicone roof coating can add years to the life of an existing roof. This is particularly beneficial for commercial properties looking to delay total roof replacement and minimize disruption to their operations.
Notes:
Silicone roof coatings are high solids, solvent-free, alkoxy-based silicone roof coatings that moisture cures to a durable, breathable, ponding water-resistant, waterproof barrier that is highly resistant to degradation from UV and natural weathering.
Correct existing ponding conditions and drainage deficiencies on all substrates before application. This is a requirement of various professional roofing associations, including NRCA, which consider ponding water undesirable and recommend that roofs be designed for positive drainage.
