While most modern roofing systems are designed to be constantly exposed to the sun, that doesn’t mean your HVAC system has to work harder because of the hotter temperatures indoors. Add that with humidity from the heat, and it becomes even more difficult to have cooler air indoors. Your roof’s longevity will also be affected and will deteriorate steadily over time, ending up with a costly roof repair.
If you’re wondering how you can prevent excess heat and humidity from affecting your roof, Sully-Jones Roofing gives more insight on what you need to know:
The Problem With Heat and Humidity
Extreme heat exposure causes the roof’s wood rafters, joists, support beams and decking to stretch, expand, crack and break. This lets water penetrate your home, which can lead to mold growth and mildew problems. The heat from the sun’s rays also gets trapped into your home’s attic or crawlspace and can cause roof nails to pop as well as shingles to curl, shrink and even blister.
Moisture can also damage your roof and its inner wood materials. This happens when it gets trapped as condensation in your attic or crawl space, which leads to mold forming on the roof rafters and floor joists. This will make the wood rot and weaken the plywood roof sheathing.
If you’re already having problems on your residential or commercial roofing system, it should get repaired as soon as possible. Delaying or ignoring a needed roof repair is not recommended, as it will only become more costly later on when the problem gets worse. It can even lead to a complete roof replacement, which could have been avoided.
Having a proper attic ventilation system will also minimize the effects of heat and humidity on your roof. Poor air circulation and roof venting will only invite mold to grow on interior surfaces, as well as water damage with the condensation dripping from the roof to your ceilings.
