When the sun gets too hot, your roof works hard to protect the building occupants and business assets from the damaging UV rays. But over time, the sun's heat takes a toll on the roof, making it weaker. This situation is usually more severe on a dark-colored roof since it retains heat. This article describes how extreme the situation can get and what a commercial roofing specialist can do to minimize the sun's effects on your roof. Continue reading to find out more.

How Bad Can the Situation Get?

There are various ways extreme heat can damage your roof. First, it weakens the roofing materials, causing them to crack, curl, and break down with time. These effects significantly reduce your roof's lifespan. Besides that, the sun's heat causes a thermal shock due to the continuous expansion and contraction of the roof. These processes result in a cracked or disintegrated roof. Additionally, some parts of the roofing may begin to pull away due to the excessive heat. Ultimately, the fasters loosen while the seams open up. 

The other effect of the sun is UV damage, which destroys not only the roofing material but also its molecular structure. When this happens, the hydrocarbon components on your commercial roof get exposed to oxygen leading to a brittle, cracked roof. The protective layer also deteriorates, leaving your roof vulnerable to rusting.

Naturally, a hot roof will emit heat into the building's interior space. That will translate to increased cooling costs and hiked electric bills. Your commercial roofing contractor can recommend energy-efficient roofing options to avoid this situation. 

What Can Your Roofer Do to Protect Your Roof from the Sun's Heat?

Working with a reputable roofer is the only way to keep your roof working all year round. The first step is having your roof inspected once a year. An annual inspection enables your roofer to spot roofing issues such as cracks, curling, or buckling early and fix them in time. 

Moreover, a poorly ventilated roof is susceptible to heat damage. Again your roofer needs to address ventilation problems during the routine roof inspection. Another solution to remedy the damaging effects of the sun is to install a heat-resistant coating. In doing so, your roof will reflect the heat instead of absorbing it. The coating also prevents the effects of thermal shock.

Your commercial roof is made of tough materials that can last for years. However, its durability all boils down to how well you take care of it. In that regard, it is advisable to partner with a competent commercial roofing company to maintain your roof in top shape.
