It’s a Scorcher: How Hot Weather Affects Your Roofing and Siding

First up, let’s talk ventilation. A well-ventilated roof is like a well-oiled machine. It works smoothly and lasts longer. On hot days, poor ventilation can cause a buildup of heat and moisture in your attic, which can make your entire home uncomfortable. Not only does this mean your air conditioning has to work harder (hello, higher energy bills!), but it also puts undue stress on your roofing materials.

A well-ventilated roof can help in dissipating this accumulated heat, thereby prolonging the life of your roofing materials. Here is an example of a project we did in Lake Zurich, where we added ventilation and opened the roof to lower heat retention:
