Why roof coating is necessary?
The humidity to dry climate and weather change can be harmful to the roofing and structures, especially the flat roofing on commercial and industrial structures. It is because of the climate and weather, that roof coating is a necessity.
For all the benefits that a flat roof provides a commercial structure, it also provides several challenges. One of the biggest is the drainage. If the unique drain system is clogged, then water tends to pond which can cause damage to a flat roof, which is why a waterproof roof coating is necessary.
Liquid waterproofing is a unique roof coating that waterproofs and weatherproofs a flat roof. While it is recommended and used on flat roofing, it has also been used on other types of roofing with great success.
A good quality liquid waterproofing will last up to 20-30 years when the proper installation process is used, and consistent roof maintenance is followed. Liquid waterproofing comes in the forms of fiberglass liquid membrane or fleece liquid membrane.
Although the Elastomeric roof coating has been around a long time, but yet, many flat roof building owners and managers aren’t aware of the advantages of this product.
Is elastomeric roof coating good?
There are many advantages and benefits of elastomeric roof coating which can prove extremely good for your roofing, like reflective silicone roof coating here.
The Cost: In comparison to a roof replacement, or roofing membrane application, the elastomeric roof coating is a lot cheaper. Because there isn’t any tear off of the old roof and much labour works involved. it is applied directly over the existing, there is less labor expense. That factor alone can save you as much as 70% of the install.
Extended Lifespan: Elastomeric roof coating is known for the quality it provides in extending the lifespan of an existing flat roof. The average commercial roof gives you up to 20 years of life and with an elastomeric roof coating, you can expect another 15 to 20 years before needing a roof replacement.
Energy Cost Reduced: A roof coating improves a structure’s energy efficiency by reflecting the UV rays of the sun with its white color, as much as 90%! Dark color roof coatings absorb those UV rays and penetrate them into the building.
Sustainability: Environmentally friendly and sustainability are big concerns for the world today, and elastomeric roof coating answers those strict building codes and stringent environmental regulations. In addition to the energy efficiency, the elimination for landfill waste is a huge plus.
Environmentally Friendly: Elastomeric roof coating have little to no volatile organic compounds (VOCs), making this a safer roofing material for the environment.
How do you install silicone roof coating?
Installing an elastomer silicone roof coating is a simple process and a single-ply substrate is an ideal candidate for a silicone roof coating. There are two key limitations to using silicone for restoring a single-ply flat roof:
It will not adhere to an oily film, common on a flat roof membrane the first five years, requiring a primer be applied first.
If the scrum of the single-ply membrane is visible, the roof coating isn’t going to work, the roof needs to be replaced.
The basic steps for applying a silicone roofing coating are:
A thorough power wash of the old roof surface ot clean the new roof;
Apply a single ply primer if required by above limitation and no need for new roofs;
Any moisture on roof that is more than 500 square feet should be replaced, not too dry and no too wet;
Apply Butyl Fleece Tape and coating to any flashings that isn’t watertight;
Install the silicone roof coating no less than 20 dry mils or as designed maps;
If it is used for metal roof coating, clean all rust off with a wire brush and apply a rust inhibitor.
How long does roof coating last?
A professional roofing contractor will know how to apply a silicone roof coating to get the best results.
With elastomeric silicone roof coating, to get a 10 year warranty, you need to have 20 mils applied to the roof. To get a 20 year warranty, 30 mils of roof coating is required. Most elastomeric roofing will last 20 year or longer.
