When you think of damaged roofs, you probably think of heavy storms and falling trees. However, strong ultraviolet rays are some of the most common culprits for roof damage. Your roof endures exposure to sunlight day after day, and although the effects are gradual, you’ll certainly notice them in time. Here are some of the most common types of damage sunlight can cause to your roof.
How Does the Sun Damage Your Roof?
1. Causes Warping
One of the most common visual indications of sun damage is warping, which happens when your roof’s materials curl or bend. This is especially common with older materials. Metal and plastic components are also susceptible to warping damage, as they heat up quickly and maintain that temperature for extended periods. The effect may be worsened if temperatures are high during the day and drop dramatically overnight. This drastic difference in temperatures causes roofing materials to repeatedly expand and contract, which can cause structural damage.
2. Weakens Coating
Think of your roof’s coating as sunscreen for your home. It protects the roof’s integrity, reduces the likelihood of water damage, and prevents premature structural failure due to the sort of cracking or warping mentioned above. However, radiation from the sun can still penetrate the coating and cause it to deteriorate over time. This reduces the coating’s efficacy and puts your roof at risk.
3. Leads to Decay
Most significantly, exposure to sunlight can cause your roof to decay. Heat causes many of your roof’s most critical components — like joists, decking, and rafters — to expand. This turns your roof into a welcome environment for moisture intrusion; the resulting mold and mildew can cause significant decay throughout your roof. Minor roofing repairs may be sufficient if the problem is localized, but it’s difficult to detect these issues before the decay has spread.
