If you own a house and have ever needed to invest in roof repair in New Bern, NC, then you know the cost can range from very reasonable to very expensive, depending on the type and size of the rooftop damage. The thing about roof maintenance is that it’s something you need to keep up with all year round, because you want your roof to move water away from your house in springtime and protect the indoor environment from excessive heat during the hot summer months.

Speaking of the summer heat, do you know how the high temperatures from the sun’s rays affect your roof? Here’s what you need to know.

Ultraviolet exposure

Ultraviolet (UV) rays from the sun are always present, even if there’s cloud cover. However, UV rays are especially harmful to roofing shingles, other roof materials and rooftop features during long, extra-sunny summer days. Because these rays are constantly beating down on your roof, don’t be surprised when a roof inspection detects age and decay. The energy from the sun at this wavelength is not visible to the naked eye, but it’s the main cause of such issues as bleached wood, weakened spots, cracks, buckled shingles and more.

High heat

Heat is a top cause for residential roof repair in New Bern, NC. When your roof is not shaded by large trees or other homes or buildings, the dark color of the shingles absorbs heat. This means the temperature of your rooftop can easily reach as high as 160 degrees Fahrenheit or more on a 90-degree day. Unfortunately, these types of high temperatures have the ability to accelerate the kinds of chemical processes that can cause roofing and construction materials to break down faster. Make sure your attic is properly ventilated to prevent heat buildup from raising the temperature and creating condensation in the main parts of your home.

Thermal shock

During the hottest times of the day, your roof can get unbearably hot, but it’s able to cool down fairly quickly when the sun sets for the evening. However, the downside of this summer night cooldown is that it can cause roofing and construction materials to expand and contract. The roof’s structural integrity can weaken and become compromised over time, especially if you have metal roofing shingles. The expansion and contraction process is problematic for metal in that its shape can warp, creating gaps that the elements can get through.

Summer storms

Summer is not all sunshine and heat waves. In fact, there are summer storms to prepare for. Elements like wind and hail can cause problems with your roof’s integrity, which is why dealing with any noticeable issues in the springtime—such as damp patches under eaves, clogged gutters and damaged shingles—can ensure it’s in good shape for the summer months. No matter the season, you should fix damage caused by trees or other objects falling onto your roof.
