How Long Do Roof Coatings Last?
The main reason why we apply roof coatings is to prevent hazards that damage a roof’s integrity. Every homeowner would probably use roof coating to avoid leaks of water, slow down the growth of moulds and moisture that wreak havoc on roof membranes, and extend the life of their roof.
The roofing system without a roof coating is missing a big point because waterproofing is a critical issue that can degrade a roof prematurely. A roof that can outlast the performance of another roof is dependent on how your roofing engineer makes use of ways to enrich the integrity of the roof. Thus, roof coating plays a big part in it.
Benefits of roof coating
Roof coatings are incredibly elastic and thicker than paint. Their elastomeric properties are a result of correct curing and produce a thick film yet durable enough to seal even the smallest seam and crack. Roof coatings, like paint, come in different types to conform with different roof materials.
The life of your roof and its assemblies should be taken cared to maintain its protective ability. When having a new structure, a roof coating is applied to prevent the roof from weather damage. UV rays, water, wind, and snow are harmful to the roof, and paint is not enough as protection. Existing roofs with a single-ply membrane, bitumen, BUR (tar and gravel membranes), ethylene propylene diene terpolymer (EPDM), spray polyurethane, and metal can have a roof coating applied.
Roof coating works best to seal seams. EPDM roof.
Types of roof coatings
Roof coatings come in different types. Let us take a look at these options to have an understanding which coating type suits best or complements your existing roof material.
- Acrylic—is an elastomeric roof coating more applicable to sloped roofs. It is less expensive and has excellent reflective properties against UV rays.
- Silicone—synthetic polymer used as a sealant against penetration from air or water. Silicone roofing stops leaks due to its waterproof property, reflects UV rays, and keeps the roof at an average temperature. Applying silicone based on thickness adds years to your roof. Silicone roof coating is an expensive option but does need a primer before its application, allowing you to save on materials.
- Polyurethane—a solvent-based roof coating, with high resistance against abrasion. Suitable for flat roofs where foot traffic is more common.
- Asphalt—works on roofs based on asphalt, with high water adaptability and is also UV reflective.
How long can a roof coating last?
Roof coatings do not last for a lifetime, as the surface wears out through time. Roofers know better about the types of coating for your type of roof. Issues on recurring leaks, damaged membrane, or inadequate insulation performance could be addressed quickly when you get a licensed roofing contractor. Expect that in an efficient roof coating, even leaks not seen by the naked eye should be fixed.
Roof coatings last based on the thickness applied on the roof. The ideal time it can last is ten years. Imagine that the additional years for your roof’s lifespan is a matter of making the right decision and knowing how to improve the stability of your roof. However, the extensive protection of roof coatings depends on your area and weather conditions, too.

Why do we need roof coating?
Why do we need roof coating if the roof material we used is among the best in the industry? The roof alone is not enough to serve as a barrier against harsh elements. Oddly enough since the roof is a cover that helps protect, why does it need protection?
Coating a roof is adding a membrane strong enough to dismiss potential hazards to your roof. Without a roof coating, the materials laid upon are also exposed to harmful elements.
Roof coating all leads towards extending the roof’s life
- Roof coats make your roof waterproof—that’s a guarantee.
- Roof coats are applicable on different roof surfaces.
- Roof coats prevent premature fading of the roof surface.
- Roof coatings save energy and reduce heat and control the temperature inside the structure with their UV-reflective property.
If you want to ensure to get the roof coating that lasts the longest, consider your primary purpose for applying roof coats. Are you headed for a roof repair? Do you want to save on energy? Or is your location prone to weather hazards?
