While we can all hide out inside during the summer months, the same buildings that offer us that comfort are taking the brunt of the sun’s heat. Roofs directly exposed to sunrays can heat up to over 180°F (depending on their color).
Just because the interior remains cool doesn’t mean the heat and light impacting your roof is insignificant. In fact, it can take a large toll on the structure in several ways.
Let’s go over how high summer temperatures can affect your roof and lead to degradation and ways you can prevent this!
UV Light & Your Commercial Roof
Ultraviolet light hits your roof regardless of the season, so UV radiation damage is always possible. However, this is especially pronounced in the summertime when the sun’s rays hit your roof with full force.
Roofing materials can get bleached and discolored as well as functionally damaged. This isn’t just a problem when the roof is exposed to direct sunlight either – UV rays can also penetrate on overcast days.
Summers can get extremely hot, especially in southern states, which takes its toll on roofing structures.
Light and heat accelerate the rate at which materials deteriorate, which impacts both the quality and appearance of your roof. Heat damage can dry out the roof’s protective oils, making it brittle. This leads to cracks, buckling, peeling, and splitting.
Heat won’t necessarily cause rust, but it will accelerate corrosion, worsening the problem. This is an even worse issue in humid environments.
Rust can do a number on your metal roof on its own, but when it’s combined with high temperatures and additional damage, the problem is only made worse.
Humid air creates condensation and water collection. The moisture weakens building materials and can even cause mold to develop, posing a health hazard.
This won’t only damage your roofing but may compromise the integrity of the entire building. Moisture is exceptionally destructive for materials made of wood and could severely shorten a roof’s lifespan.
A roof can reach extremely high temperatures when exposed to midday sun rays. However, once nighttime rolls around, the temperature will quickly drop.
This sudden fluctuation in temperature causes the materials to expand and contract, which puts stress on your roof, creates tension, and compromises the structural integrity. Over time, this could lead to a warped or split roof.
Prevention of Commercial Roof Damage
While you can’t prevent hot sunny days, humid air, or drastic cooldowns, you can take some measures to protect your roof before any severe damage occurs. Taking good care of your roof and solving problems on time will prevent further or accelerated degradation.
You can do this with regular roof maintenance. This means the immediate repair of any damage, even superficial. Maintenance also includes cleaning debris off of the roof.
To combat the heat, you can also ensure sufficient attic ventilation. This can help keep the temperature from rising inside your building and prevent condensation and moisture issues.
Finally, ensure that you regularly get your roof professionally inspected so that problem areas don’t worsen. A professional will be able to notice any signs of sun damage and affected areas and offer a ready solution.
