Need roof work but you’re worried it’s the wrong time of year? Are you concerned it’s too hot or too cold to fix issues on your roof?

You’re not alone. Homeowners ask me this question all the time! Luckily, my answer is pretty simple, because temperatures in the Myrtle Beach area rarely exceed the limits set by shingle manufacturers. So, Linta Roofing can complete roof work all year long! In the event that temperatures rise or drop significantly, we typically reschedule a roofing project for a few days later or until the temperatures have evened out. But our customers never have to suffer through an entire season before we repair their roofing problems.

While this is usually the case for the Myrtle Beach area, it’s important to check the installation instructions provided by the manufacturer. Because GAF is the largest shingle manufacturer in North America, we’ll use them as an example and describe what their installation instructions include in reference to safe installation temperatures.

When is it Too Hot to Replace a Roof?

GAF installation instructions state that any temperature under 90 degrees is considered a standard installation. It is important to note that GAF is referring specifically to temperature, not the heat index, not humidity, or the ‘feels like’ temperature you may see on your weather app.

hot temperature outsideGAF also includes special instructions in the event that you need roof work and temperatures are above 90 degrees. If a roofer follows these specifications, there is no need to worry about the durability of your roofing system. To ensure the installation process is completed thoroughly, hire a reputable roofing contractor in your area. I generally suggest homeowners find a certified roofing contractor to complete their roofing project. 

If the temperature is under 90 degrees, this is considered a standard installation, meaning your roofer would not be required to complete these additional actions. But this begs the question, what temperature is too cold to replace a roof?

When is it Too Cold to Replace a Roof?

Based on GAF’s installation instructions, shingles should not be applied to a roof if temperatures drop below 40 degrees unless special measures are taken. The reason for this is because shingles have an adhesive strip that secures them to one another. The adhesive may not activate if temperatures are below 40 degrees. However, there are special instructions a roofer can follow to ensure that the shingles properly seal together even in low temperatures.

When temperatures dip below 40 degrees, your roofer will apply sealant underneath the shingles in order to start the sealing process. So even when temperatures get cold, it's likely that your roofing project will still be completed as scheduled. However, I know you still may wonder “When is the best time to replace my roof?”

The Best Time to Replace Your Roof in Myrtle Beach

Regardless of temperature, I always advise homeowners to have a roof replacement before hurricane season, which is typically during the springtime. But at the end of the day a reliable roofer can replace your roof any time of the year in our area. If you need a replacement, it’s important to get on top of any issues with your roof right away to avoid interior damage.

Ultimately, I’m in the business of keeping families safe. And the last thing I want to do is install a roof against manufacturer's guidelines. Our goal is to provide peace of mind from beginning to end and provide you with a safe and beautiful new roofing system. And if you’re curious about the cost of your new roofing system, we’re happy to provide you with a personalized estimate in less than 60 seconds!
