What is the Best Temperature for Replacing a Roof?

Less than optimal temperature to replace a roof

The whims of the weather have always impacted our daily lives, and it also can constrain our ability to install a roof. Yes, it can be too hot or too cold to replace a roof in Austin.

Asphalt shingles, which are by far the most common type of roofing material for residential roofs, should be installed when the temperature is between 40 and 85 degrees Fahrenheit, with 70-80 degrees being the sweet spot for roof repairs and replacements. 

What Happens When the Temperature is Too Cold?

When the temperature dips below 40 degrees F, asphalt shingles can become brittle and prone to breakage. You should never use damaged shingles on your roof, so the more unusable shingles you encounter during installation, the more expensive your project will be.

Moreover, roofing products require adhesive that needs the sun’s heat for activation. If the right conditions are not achieved during the roofing process, you could risk having a faulty seal on your shingles. Some warranties may also be void if installation occurs when the temperature is below 40 degrees. 

What Happens When the Temperature is Too Hot?

Conversely, if the temperature climbs too high you risk damage in the other direction. Shingles can become too pliable, lose their original shape and be easily damaged during installation. The adhesive may also dry out too quickly when the temperature is very high. Humidity levels are another factor that will impact shingle installation.

The reality for many homeowners, however, is that we don't always have a choice about when we replace our roof. Emergency situations may necessitate a roof repair when it is very cold or very hot in Austin (and Central Texas at-large). Rest assured, there are ways to work around temperature constraints and still fully and effectively repair or replace your roof. We can help.
