What Georgia Humidity Does to Your Roof

No one’s denying it’s hot here in Georgia. By the time summer rolls around, you can expect the humidity levels to hover somewhere between 99% and “hope you brought another shirt!” That humidity is hard on your hair, yes, but what about your roof? What does the relentless GA moisture mean for the functionality of one of your home’s largest – and most expensive – components? What is humidity, really? Humidity is essentially water vapor trapped in the air. The reason humidity is so high in the summertime is because warm air can hold higher concentrations of vapor. Humidity can be present when there’s no rain the forecast or it can linger in the wake of a storm. What does humidity do to your roof? Nothing good. Let’s talk about all the ways, both subtle and major, the humidity here in Georgia can wreak havoc on your roof. Lumber: Your roof is a actually and entire system, of which lumber beams play a large role. Humidity in the air causes that lumber to constantly expand and contract which over time will weaken the roof’s structural stability. Single-Tear Strength: As the humidity gradually weakens the places where your roof is held together, it’s in turn making it more vulnerable to wind. A roof that’s been weather-weakened is more likely to rip off in tornado or hurricane-force wind gusts. Decking: Humidity can cause the edges of your decking boards to absorb water. This will naturally lead to separation which causes major deflections along the plane of your roof. When water can’t run off your roof efficiently, leaks happen. And that’s just your roof. Next, let’s talk about… What humidity does to your attic ventilation system Your attic and, more specifically, its ventilation system, is a critical component of your roofing structure. Allowing air and moisture to effectively move in and out of your attic space ensures your roof will work properly and that your HVAC system won’t be spinning its wheels. What does humidity do to this ventilation process? Mold and Mildew: Yuck. Lingering moisture quickly leads to mold and mildew build up on the organic components of your attic such as the beams, stored items, or even certain insulations. This can actually make you and your family sick. Rot: Wood rot is a serious problem when it happens inside your attic –…

How to Protect Your Roof from Tornadoes

Since 1950, there have been more than 1,700 confirmed tornadoes here in Georgia. When the weather heats up, tornadoes become more and more likely – and they’re a huge risk to both people and structures. What can you do to ensure your roof makes it through tornado season, which peaks in May, unscathed? More than you probably think. Replace with Intention Are you already thinking about replacing your roof? If so, your roof is probably starting to age and likely isn’t as tornado-proof as it could be. You actually have a lot of options when it comes to choosing materials and installation methods that will better withstand the severe winds of a tornado, so talk to your roofing professional in Georgia. Choose the Right Material Metal roofs are, by and large, the best choice if you’re truly prioritizing tornado resistance. Metal itself holds up better to direct hits from debris and it’s heavier and less susceptible to gusts of wind. That being said, an improperly installed metal roof might actually be more likely to blow off in a storm, so be sure you’re working with a professional roofing contractor. Reinforce Retroactively Did you know that most roofs can be reinforced retroactively to make them stronger against wind? Talk to a local roofing professional in GA about hurricane clips. They’re essentially just fasteners that connect your roofing structure to your rafters and beams, but they provide significantly more stability when it comes to inclement weather. They’re also far less expensive than replacing your entire roof! Clean Up Debris At the end of the day, it’s not the wind you should be worried about in a tornado, it’s the debris. Making sure your property is clear of the kind of debris that can wreak havoc on your roof is your first line of defense. Consider everything from low-hanging branches to patio furniture to entire dead trees that threaten your property. Taking action now can save you a lot of hassle (and expense!) down the road. Schedule Regular Inspections A well-maintained roof is a strong one. The absolute best thing you can do to protect your roof against tornadoes – and any kind of severe storm – is to have it inspected early and often. A once a year inspection by an experienced Georgia roofer can spot issues that could cost you thousands down…
