Renewable Roof Coatings for Metal Roofs

Metal Roof Roof Coatings are Renewable and Expandable

A metal roof coating works best if it is applied to the entire roof surface at once, but it is not unheard of for a roof coating to be used to mend or repair a metal roof in just a spot here or there. The rest of the roof can be coated in due time and will be every bit as good as a roof that is coated all at once.

Plus, unlike traditional metal roof repair options, a roof coating can be renewed every so often with a fresh coating of the entire roof surface or just a small area can be coated to repair or reinforce a weak spot. Roof coatings are fairly lightweight so it's possible to restore the roof by adding another layer every few years.

A Roof Coating Warranty Can Be Renewable Too

Most warranties start at 10 years, but with proper roof maintenance and regular inspections, a metal roof coating and its warranty can be renewed for decades. As with any substrate covering, as long as the top coating roof seal remains solid, the substrate will remain strong as well.

The Advantages of Metal Roof Coating

One great advantage to coating a metal roof is that in many cases it means you don't need to tear off the old roof and haul it off to landfill. This not only saves the building owner the cost of a new roof, it also helps preserve our environment by reducing landfill waste.

Another great advantage to a metal roof coating is that in most cases, a roof coating qualifies is considered building maintenance, which can lead to huge tax breaks for the building owner.

Other obvious advantages to a metal roof coating are a waterproof roof and a stronger roof surface. Roof coatings are durable and expandable. Measured in Mil thickness, a roof coating is more than just paint. It's a measurable membrane that can be recoated as needed.

One some what unknown advantage to a metal roof coating is that it is elastomeric. This means the coating is rubber-like and has the ability to expand or contract and then return to its original shape. This hidden benefit is very important because of its ability to handle the effects of thermocycling, which is the process of going from hot to cold, and is a major contributor to premature roof breakdown.

Don't Forget - Metal Roof Coatings are Eco-Friendly!

Another way roof coatings are environmentally friendly are through their energy efficiency. Roof coatings are cool roofing systems that keep energy consumption costs and green house gas emissions down to a minimum. So you can do your part for the environment while you save on your energy bill, too.

One of the best things about a roof coating though is that in 9 out of 10 cases, the roof coating can restore an existing roof surface back to good as new performance without needing to tear off the old roof. This saves the building owner the cost, headache, and mess associated with tearing the old roof off and hauling it away to the local landfill. Another little eco-friendly benefit to using a roof coating for your next flat roof project.

Savings Savings Savings

Besides affordable installation, a metal roof coating can save the building owner with climate control and energy costs savings. A bright white metal roof coating can lower a building's roof top temperature by several degrees which makes it easier and more affordable to control the interior climate resulting in lower electricity bills.

Less roof maintenance is also a cost saving component of a roof coating. The roof coating completely seals the roofing substrate thereby protecting and preserving the roof from premature degradation and wear. A bright white roof coating also reflects the sun's harmful UV rays away from the roof which reduces thermocycling. Any reduction of thermocycling can add years to a roof lifespan.

Metal Roof Coating Lifespan

With proper maintenance, most metal roof coatings will last for many years and can be backed by a manufacturer's long term warranty giving the metal roof a decades long lifespan.

All roofing systems recommended by American WeatherStar may qualify for such an extended warranty. Contact us for more information on our extended metal roof coating warranty programs.

Our Metal Roof Coatings are Cool Roof Coatings

A cool roof is a roofing system that combines exceptional solar reflectance with high thermal emittance properties to produce a roof surface that is energy efficient and therefore runs much cooler than a standard roof. A cool roof is usually bright white to help with reflectivity and a roof surface temperature that is up to 50°F cooler than a dark colored roof...imagine how much cooler the interior comfort will be with a metal roof coating from American WeatherStar!

Here is an infrared image of a roof coating in progress. Note how the temperatures of the coated portions of the roof are running as cool as the greenery around the building while the uncoated portions of the roof are running as hot as the black roof next door and the asphalt roads.

Even in areas where the days are simply sunny and not necessarily hot, a cool roof coating can add many advantages listed that are not available with traditional roofing systems.

The Benefits of a Cool Roof Coating for Metal

A cool roof coating over metal can benefit the building owner through reduced heat gain which leads to lower energy bills and less wear and tear on the building air conditioning system. This means less roof maintenance and longer life for the roof and the HVAC systems, plus:

• Improved Thermal Efficiency

• Increased Interior Comfort

• Decreased Energy Consumption

• Smaller Utility Bills

• Less Wear and Tear on Mechanical Systems

• Better Reflectivity

• Enhanced Thermal Emittance

• Longer Life Span for Roof and Mechanical Systems

• Less Roof Maintenance and Repairs Required

• Reduction of Greenhouse Gas Emissions and Air Pollution

• Keeps Old, Deteriorated Roofing Materials Out of the Landfill
