By most expert’s estimation, a decent painting has a lifespan of eight to 10 years. The durability of your roofing is critical for curb appeal and the safety of your home. It is one of the reasons why your roof needs a coating that can protect it and enhance its lifespan.
But what makes the coating on your roof last? In this article, we outline some of the factors that can extend the life of the paint.
1. Resistant to UV Degradation
One of the essential features of a durable roof coating is its ability to resist UV radiation. Acrylic paints are excellent for guarding against the effect of the sun’s rays. For flat roofs, consider a specially formulated elastomeric coating for additional protection. You may want to consult a painting contractor in Tucson to determine the best coating for the surface.
2. Adhesion and the Compatibility of the Substrate
The adhesion of the roof coating is another aspect an exterior painter will have to consider. Manufacturers have developed different types of paints that can adhere to various substrates. These products have formulations designed for specific roofing materials such as concrete, metal, or SPF.
For maximum durability, you should choose a coating with the best formulation for your type of roof. Also, professional exterior paint contractors will clean and prepare the surface for maximum adhesion. Despite the additional costs in time and resources, preparation ensures the paint will last longer.
3. The Value of Dirt Pickup Resistance
A roof coating ought to be as resistant to dirt as much as possible. Grime and debris can adhere to the surface and damage the roof in several ways. It can diminish its ability to reflect light and heat radiation, which reduces your home’s energy efficiency.
The dirt can also ruin the aesthetics and curb appeal of the property. It may also encourage mold and mildew to grow, which will eventually peel off the coating. Your painting contractor can help you choose between elastomeric and acrylic paint, depending on the substrate.
4. Standing Water Resistance
Standing water is one of the most significant challenges when it comes to maintaining your roofing. Some paints cannot tolerate pools of water that take time to drain. The higher the resistance, the more the roof coating can withstand peeling and blisters.
Acrylic roof coatings are more vulnerable to standing water problems than silicone. It has a hydrophobic surface, meaning it has no pores that can allow water through. However, silicone is more slippery, and therefore, not suitable in areas with foot traffic.
5. Ability to Withstand Temperature Fluctuations
You may also choose a paint that has tolerance for extreme temperatures. Low or fluctuating temperatures can increase incidences of cracking on the surface. A quality acrylic roof coating is resistant to most weather conditions. Its ability to resist low temperatures is critical for places with frosty weather in winter.
Choose a Durable Roof Coating
You need to keep in mind that the underlying substrate is crucial when choosing a suitable roof coating. It also helps when you prime the surface before applying the paint, regardless of the material you’ll be painting. Also, consider consulting an exterior paint contractor for lasting results.
