When Is It Too Cold to Roof?

WHEN IS IT TOO COLD TO ROOFWhen is it too cold to roof

When is it too cold to roof?  It really is too cold to roof when you are outside and you can see your breath.  Many roofing products have adhesive properties that require the sun’s radiant heat for activation.  You risk a faulty roof install if you do not pay attention to the temperature outside.  Continue reading for specific cold weather roofing tips.    

ASPHALT SHINGLES

The ideal temperature range to install asphalt shingles is between 70 and 80 degrees Fahrenheit (21 and 27 degrees Celsius). Below 70° F and the adhesive will not reach the ideal elasticity and will not create a perfect seal. Temperatures  warmer than 80 degrees can be problematic in the other direction. Asphalt shingles can become overly pliable and are susceptible to damage during installation. Installers are more likely to overdrive roofing nails, and foot traffic can er
ode the protective granular layer quite easily in extremely warm temperatures.

If winter installation is unavoidable, most asphalt shingle manufacturers require a specialized adhesive manually applied to each shingle for temperatures below 40° F (4 degrees Celsius). If shingles are applied below 40° without the specialized adhesive, you risk a voided warranty.

EPDM

EPDM (rubber) membrane roofing is even more temperature sensitive than asphalt (composition) shingles. EPDM is joined together using an extensive amount of adhesive that requires high temperatures to be pliable enough to install and cure. EPDM adhesive is very thick and hard to work with even at high temperatures. How cold is too cold to install a new roof?  Manufacturers recommend temperatures be above 45° F  (7 degrees Celsius) for installation. When the weather is too cool to roof, that recommended temperature is not very practical unless a warm storage area is made available to keep the adhesive warm until the moment it is used.

Roofing in Cold Weather: Keep Asphalt Shingles Warm

ROOFING IN COLD WEATHER

If you live in the United States, it’s likely your roof has asphalt shingles.  American homeowners use asphalt shingles more than any other roofing product. When applied correctly, these will provide many years of protection. Unfortunately, if you are roofing in cold weather, you will need to take some extra precautions.

SHINGLES NEED WARMTHroofing in cold weather

As temperatures decline, shingles become more brittle, and are easily cracked and broken. Cracks lead to one thing: water leaks.

Years ago it was common for shingles to crack and blow away in wind storms. Manufacturers solved this problem with a self-sealing compound that cements one shingle to another (a thermoplastic compound). Introduced in the mid-1960s, it is a common ingredient of virtually every asphalt shingle manufactured.
The sealing compound is activated by the heat of the sun. This sealing can happen in colder temperatures, but direct sunlight is required.  North sloped roofs may not get the necessary sunlight until spring/summer. When the bonding process is complete, the shingles are less likely to develop wind-related leaks and failures.

The ideal temperature range to install shingles is between 70 and 80 degrees Fahrenheit (21 and 27 degrees Celsius). If temperatures are colder than 70 degrees, the adhesive will not reach the ideal elasticity and will not create a perfect seal.

If roofing in cold weather is unavoidable, most asphalt shingle manufacturers require that a specialized adhesive is manually applied to each shingle for temperatures below 40 degrees Fahrenheit (4 degrees Celsius). Failure to apply the special adhesive in adverse temperatures will void the manufacturer warranty.

The Powerblanket Hot Box (also known as our Bulk Material Warmer) is a versatile tool that can be used for a myriad of applications, and roofing is one of them. When you need to keep your materials warm and ready to use, the Hot Box is a great and economical way to maintain material warmth.

Sometimes material warming is merely a matter of protecting your supplies from freezing in cold weather. If not freezing, protecting them from inefficiency is equally important. The Hot Box executes these jobs extremely well. Temperature regulation and heat application for tar, adhesives, laminates, mineral surfaced roll roofing, and all other roofing materials are easily accomplished with the Hot Box.

What’s more, if you have materials that need more than just protection from the cold, the Hot Box helps there too. Certain roofing materials need to operate at high temperatures whether in moderate or cold weather. By using the transportable and easy-to-assemble Hot Box, you can keep your materials at the ideal temperature regardless of what’s happening with the weather.

The Powerblanket Hot Box is designed with great structural integrity. Every unit comes with an internal, freestanding frame and can be easily assembled, disassembled, and reassembled.
