Summer Heat Effects

Aug 1, 2019 | Roofing

Which season is the hardest on your roof?

Many people are often unaware of just how much damage summer’s sweltering heat and unrelenting sunlight can do to a roof. If your roof starts to leak and you discover it during the winter, odds are the leak actually developed during summer because of one of a number of reasons. 

Causes of Summer Sun Damage

Sunlight may be warm and inviting but sunlight also has a number of harmful effects in mass quantities due to the types of radiation it contains. Notably, sunlight is full of ultraviolet (UV) radiation, which is invisible to the human eye but can deal immense damage to most anything left in it. 

Over time, anything left exposed to ultraviolet radiation will begin to break down and degrade, including your roof. This means the tiles on your roof will become more brittle and porous, the underlayment stiff and cracked, and the wood structure weak and splintered. High-quality roofing tiles can help negate this effect for some time, but eventually even the most durable of roofs will finally give out 

Additionally, the heat and wide temperature swings of the summer months can also deal damage. As the materials of your roof heat up during the day, they expand, growing slightly larger. As they cool, they contract back down towards their normal size again. This constant cycle of expansion and contraction is known as thermal shock. Different materials will react differently to thermal shock, and some are certainly better-suited to it than others, but over time this will contribute to any roof wearing out. Eventually, thermal shock could cause splits or cracks to form in your roof, leading to leaks and potentially costly repairs. 

Avoiding Summer Sun Damage

Now that you’ve learned why the sun can damage your roof, how can you prevent it? The first step is to take care of the roof you already have. Cleaning your roof is a task you should perform annually, usually during spring time to remove any debris that may have collected on the roof during the winter rains. This will also give you an opportunity to clean out your rain gutters, allowing them to flow properly which can prevent substantial damage to your roof as well. 

What you absolutely should not do is neglect your roof. Neglecting to maintain your roof causes damage to snowball and grow worse and worse quickly. Eventually, a roof that’s left unmaintained will eventually cause serious damage to your home, or worse, fail entirely. However, with proper maintenance and a regular inspection, you can make your roof last many additional years, or even decades beyond one that doesn’t receive this regular care, which saves you money and keeps your home protected.
