How does heat affect your roof?

Sun Beaming Down on Roof

Heat can harm roof

Most of us have a love-hate relationship with the Georgia sun — and your home’s roof is no different. Both heat and humidity cause problems for our roofing, just as all extreme weather can. From extreme temperatures to storms, weather conditions can cause damage to both commercial and residential roofing systems. But by taking some preventative measures and calling your professional roofers, you and your roof will be protected from the scorching summer heat.

How heat impacts your roof

Constant exposure to the sun will increase your roof’s temperature, making your air conditioning system work harder to cool the inside of your home too. This can damage your home’s roof and the wood materials used in the structure of your home’s rooftop.

Intense or prolonged heat can cause wood roof rafters, support beams, joists, and decking to expand, stretch, and crack. We also occasionally see shingles start to curl and shrink. When the roofing system is weakened in this way, you’re more likely to see urgent issues like leaks, mold, and mildew.

How humidity impacts your roof

Moisture can become trapped in your attic or crawl space, build up as condensation, and eventually lead to mold on attic floor joists, roof rafters, and roof joists. Moisture can also lead to wood rot and weaken plywood roof sheathing, causing the layers of the plywood to separate.

Prevent roof damage and protect your home

There are a few steps you can take to protect your home and roof against both heat and humidity.

Roofing Ventilation: Proper ventilation for your home can reduce the effects of heat and humidity on your roof. Without effective air circulation through roof vents, condensation can drip from your roof to your ceilings, causing water damage. Your roofing contractor can recommend the type of roofing ventilation system that will work best for your home based on your home’s design and local climate.

Dehumidifiers: Using a dehumidifier in your attic or crawl space can prevent mold caused by condensation. Plus, minimizing moisture will reduce the air’s heat capacity.

Preventative Maintenance: It is best to be proactive and have your roof checked after major weather events, such as a storm or heat wave. The most effective way to save money on your roof is to schedule a free inspection with roofing experts. That way, you’ll catch any issues early and save costly repairs down the line. Ignored or delayed repairs will likely result in more extensive repairs and could lead to complete roof replacement. We offer several specials and financing offers to work with your budget, so you can maintain your roof with peace of mind.
