How Heat Causes Roof Damage: What to Look for During Your Next Roof Inspection
People often associate the term roof damage with heavy winds, rain, hail, or falling tree branches. However, there’s another ongoing threat to roof integrity that can weaken your roof over time. Heat trapped in your attic during periods of high temperatures can actually lead to roofing damage. Here’s a look at how regular roof inspections and prompt roof repair can prevent and mitigate roofing damage caused by heat.
How Heat Causes Roof Damage Over Time
The Portland area may not be known for extreme heat, but summers can still bring about heat waves that can be troublesome for your roofing. Heat damage primarily occurs in two ways. These are direct UV radiation and heat buildup over time. Different types of roofing are at risk of roofing damage from heat. Asphalt shingles are one of the most common roofing materials in the region. Under prolonged UV exposure, they are subject to cracking, curling, and granule loss.
Roofing Damage Signs You Shouldn’t Ignore
In most cases, roofing damage and heat damage are not immediately apparent. Instead, it’s a gradual build-up of problem areas. Some signs of roof damage to look out for include blistering shingles, popped nails, and discoloration or fading. Sagging areas of the roof should also be an immediate red flag for you. Additionally, if you notice an increase in interior temperature, even when you have the AC running, this could be a sign that heat is accumulating in your attic.
Why You Should Get a Roof Inspection After a Heatwave
Did you know that the longer a heatwave goes on, the higher the risk of damage to your roof is? That’s why it’s essential to get a roof inspection after a heatwave in Portland, Oregon.
