This past week in the Greater St. Louis area saw temperatures plummet down into the single digits. We hope all of our blog readers stayed safe during this extremely cold weather. Fortunately, the forecast calls for temperatures to be in the 50s and 60s next week, which after what we have experienced will feel very warm! But what kind of affect did the single digit temperatures have on your roof?

In this article from, experts discuss how winter can wreck roofs. We have posted below a quote from a roofing expert in that article:

Why Winter Can Wreck Roofs

The temperature changes and precipitation winter brings can cause a number of problems on your roof. “Changing temperatures can be especially tough on single-ply membranes due to a phenomenon called supercooling, in which the membrane hovers around 5-10 degrees F. colder than the ambient air temperature,” explains Tom Gernetzke, principal consultant at Building Envelope Consultants Group, LLC.

There are three major hazards extremely cold temperatures can have on your roof. Those are listed below:

  1. Frozen or clogged gutters and downspouts— Dropping temperatures can make clearing rain gutters a low priority, but snowfall combined with freezing temperatures can quickly clog rain gutters and downspouts leading to the potential for damage to the roof as well as the drainage system. 
  2. Trapped meltwater– Once the temperatures in Greater St. Louis began to warm up, trapped ice and snow start to melt, water gets trapped and begins flowing into your home causing damage to your walls, ceilings, and insulation.
  3. Ice Damming— When warm air rises from your heated living spaces, it warms the shingles of your roof and the snow that covers it. This leads to snow melting and dripping down to the colder edges of the roof where it refreezes as ice. Once the ice grows thick enough, it backs up further snow-melt behind it, causing water to seep under the shingles, and eventually into your home through leakage points. Leaks are made the more likely when backed up water freezes and thaws, working its way into nooks and crannies and expanding them.

The last thing you need to do is climb up on your roof yourself if our Greater St. Louis single-digit temperatures have you worried about whether any of the above situations have happened to your roof. There is most likely plenty of spots right now that are still frozen, or at the least unsafe, so no one but a professional roofing expert should traverse your roof after this brutally cold weather.
