Drivers living in northern climates know how rough winter can be on cars, especially the windshield. Scraping ice and snow, freezing temperatures, debris kicked up by snowplows, dodging the glass-cracking impact of potholes – winter’s damaging effects can mean good business for glass repair shops.

Hot weather also means good business, even more so than in winter. And it can make repairs challenging, especially those done on-site instead of in your shop.

With temperatures staying high year-round in some parts of the country, and summer bringing the heat to everyone, it’s a good idea to be prepared for more business when the mercury goes up.

Here are a few reasons why:

More Drivers

Nice, warm weather means more events to enjoy – vacations, heading to the beach, family reunions – which means more people out driving. And that means more chances for glass damage from accidents or flying roadway debris.

Hot Car Interiors

People enjoy saunas – but not when their car’s interior feels like one. Setting the air conditioner on full blast to cool it off creates increased stress on the glass. That can cause an existing chip or crack to expand from the quick change in the glass temperature.


Winter blizzards are not a car’s friend, but neither are summer storms. Hail and high winds blowing glass-damaging debris are not uncommon. Tornadoes occur in warmer weather. And each year hurricanes leave widespread devastation in their wake.

Keep Your Cool During Hot Weather Jobs

While these problems can be good for business, hot temperatures can cause problems on your end as well.

For example, in areas of low humidity such as Arizona, the urethane takes much longer to cure, increasing the Safe Drive-away Time (SDAT). So when it comes to warm weather repair or replacement jobs, keep these tips in mind:

  • Make sure the temperature of the glass is between 70-100 degrees. If the glass is too hot to comfortably leave your hand on it, then it’s too hot to work on.
  • Do repairs in your shop whenever possible, so you can control the temperature and stay out of the sun.

    If a job must be done outside, have the vehicle moved to a shaded area. Otherwise, the glass could be too hot to the touch.

  • If there’s no shade, lower the windows to let out the interior heat. Or, run the air conditioner on low, and use the floor vents so the cool air doesn’t blow on the windshield.
  • Resin temperature should be within 10 degrees of the glass temperature to ensure proper, even curing.
  • Keep equipment and supplies out of the sun as well so the heat doesn’t affect their performance.

Hot weather certainly has its advantages, and that includes keeping you busy. Because as the temperature goes up, so does the number of customers needing glass repaired or replaced. And that means a sunny outlook for your bottom line.
