Are Shingle Roof Repair Coatings Effective For Edmonton AB Homes?

Asphalt shingle roofs give the traditional American home its distinct look and appeal. However, it only has an average lifespan when you compare it with other durable and long-lasting roofing materials such as clay and metal. On the other hand, it is economical and easy enough for any homeowner to repair. In addition, most hardware stores and suppliers claim that asphalt shingle roof repair coatings can extend the lifespan of your asphalt roof. Is it worth spending for?

Edmonton AB's highly reputable and experienced contractors use acrylic elastomeric coating mostly on metal roofs. The glossy roofing material is an excellent conductor of heat. With coating, it can reflect UV rays and give the metal roof an additional protective coating against the elements. In doing so, acrylic elastomeric paint improves the roofing material's durability and performance.

However, not every homeowner has heard about asphalt shingle roof repair coatings and what it can do. Asphalt shingles have a rough yet artificially smoothened roofing surface. Is it possible to apply elastomeric coating on them, and if so, is it effective? You can learn more about it in-depth below.

How Do Asphalt Shingle Roof Repair Coatings Work?

Unsurprisingly, Edmonton AB homeowners can expect asphalt shingle roof repair coatings to apply smoothly as it does with metal roofs. According to National Coatings, asphalt shingle roof coatings function similarly to caulk but possess great standing water and impact resistance in addition to its reflective properties.

However, these Elastomerics are not caulks or sealants. While they must tolerate expansion and contraction, and the dynamics associated with the roof, just like a caulk or sealant. But, caulks and sealants don’t require resistance to standing water, impact resistance, or reflectivity properties. (Source)

In addition, the website's blog writes about acrylic's temperature-reducing qualities. In one data-backed study, they discovered just how well acrylic elastomeric asphalt shingle roof coatings performed efficiently in improving property insulation.

In the slide below the surface temperature of a number of different roofing materials were measured as a function of the time of day. The green line is the air temperature. The vertical axis is temperature, the horizontal axis is the time of day. And we saw that at about 2:30 or 3:00 PM, the air temperature was about 90oF (August, PA). The surface temperature was measured using the infrared thermometer of the black asphalt shingle exposed to sunlight. The yellow line at the top if the time-temp grid for a black asphalt shingle. 8:30 in the morning it started out at 85oF, by 3:00 p.m. it was up to 160oF. And by the end of the day, by 4:30, it tailed off to about 120oF.

This contrasts with the red line. This same black asphalt shingle coating with 100% acrylic elastomeric coating. The surface temperature of the shingle was much lower initially, 80oF. By mid afternoon the peak surface temperature was only about 90oF, then it tailed off into the 80’s. This shows the benefits of reflectivity as the white elastomeric acrylic coating protects the asphalt roofing material and keeps it cooler. (Source)

Can I Use Just Any Type of Acrylic Elastomeric Coating?

Acrylic elastomeric coating of any kind can work on asphalt shingle roofs. However, it pays to use an asphalt shingle roof repair coating specific for the roofing material. It is true that acrylic elastomeric is still the base material, but some small details and the included instruction will often help Edmonton AB homeowners to apply the coating properly to achieve their desired results.

Polymeric coatings are an alternative to acrylic elastomeric paints. While they're similar because of the presence of acrylics, polymeric coatings are more effective than general acrylic elastomeric roofing. Networx explains below.

High-quality white polymeric coatings are widely available. They're made with acrylics or similar materials mixed with an opaque white reflective pigment. These are probably the most effective reflective coating for the majority of asphalt roofs. Some polymeric coatings are tinted for aesthetic reasons, but they are less reflective and therefore won't save as much energy.



Tests at Oak Ridge National Laboratory and Lawrence Berkeley National Laboratory showed white elastomeric coatings offer about 60% solar reflectance, leaving the roof temperature 36 degrees higher than the ambient air temperature - a much smaller difference than that generated by a black asphalt roof. All polymeric coatings must be chosen and applied carefully, particularly on rough asphalt roofs. (Source)

When Should I Just Opt for a Straight-On Asphalt Shingle Roof Repair?

Nobody wants to ever spend a fortune, but repairing your asphalt shingle roof is sometimes the better option. Acrylic elastomeric and polymeric roof coatings can only do so much for your roof.
