Extreme Summer Heat Can Affect Your Building Roof – Here’s How

The sun makes a very huge impact on your building roof’s lifespan, primarily because of extreme heat, UV rays, and thermal shock. Did you know? Sun’s UV rays wear down your building rood every single day, and; this also includes the cool and cloudy days. The harsh rays from the sun dry out the oils present in the roof and make it dry and brittle, and; eventually causes it to lose it waterproofing qualities.

The heat of the sun accelerates the breakdown process. You would be surprised to know that your roof can reach up to 160 degrees even when it’s 90 degrees outside. Heat fastens the damage done by UV rays – ultimately your roof is left weak and it loses its flexibility.

Overlooking to maintain your roof can cause more damage, shrinking the life of your roof and costing you more money and time in the long run. Here a quick rundown of what summer heat does to your roof:

#1 – UV Exposure

Your roof is constantly bombarded with the UV rays from the sun, and this is causing it to decay and age faster than it is foreseen. You may think that this holds true for the long, sunny summer days only, but that’s incorrect as the sun’s UV rays don’t spare your roof even on the cold and cloudy days. The energy at this wavelength is not visible to the naked eye, but it sources your roofing and construction material to dispel and shingles to buckle and split.

#2 – Heat

When your building roof is not shaded, its dark color absorbs heat, touching temperatures as high as 160°F on a 90°F day. These exorbitantly high temperatures hasten chemical processes in the process, instigating your roofing materials to break down faster.

#3 – High Humidity Levels

One of the most uncomfortable realities of living in India is Humidity. The rise in temperature during the summer months results in extremely humid conditions in many regions of India. During this period, condensation and moisture can easily settle in between the shingles and the underlayment, ensuing in water leaks. In addition, once the moisture starts collecting, it gives room for molds to grow and threaten your family’s health.

#4 – Thermal Shock

Your building roof touches exorbitantly high temperatures during the daytime, and quickly cools off when the sun sets – this causes the construction and roofing materials to contract and expand. This consequently wanes your roof’s structural integrity with time.

#5 Constant Wear And Tear

By now we understand that increased exposure to direct sunlight can damage your roof. Most roofing systems are built to last; they normally have a good lifespan of 20 to 30 years but constant wear and tear due to the summer heat chases its limit. Once the heat becomes unbearable, the shingles can curl and dry up – resulting them to become extremely brittle and prone to cracking.

#6 – Discoloration On The Roof

You can blame the sun if you witness draining in the color of your once- bright roof shingles. Unquestionably, it has everything to do with the sun’s powerful UV rays. The discoloration is just one part; the other side is that discoloration can really impact the roof’s ability to do its job well. The color of the roof shingles matters because they work to reflect the sun’s light, staving off the heat damage as best as it can against its surface and the rest of the home. So not only its reflective capabilities depend on the coat and color of the shingles to keep the sun rays off, but it helps keep the inside of the home cool. So if your roof is getting discolored, your home would get hotter and hotter during the summer months.

A Roof Is More Than A Roof Over Your Head

The roof is not just a shade over your head… but it is much more than that. A well-built, roofing system regularizes the internal temperatures of a home – ultimately helps in conserving energy in a big way, it repels moisture to prevent damages from water, reflects the sun’s rays during hot summer months. The roofing system should have roof shingles having a reflective coating, ventilated to prevent heat build-up, and a gutter system to guide rainwater away from not just its surface, but from the entire home.

Now that was about what the roof can do your you, more importantly, there is something you can do for your roof. Indicating “Roof Inspections” – these are a crucial element in keeping your roof well-maintained and prevents damage from the extreme summer heat. Replace damaged shingles immediately and have a professional examine your roof annually. You will surely extend its longevity and your roof will pay back silently in its own ways!
