No matter the season, harsh UV rays can take a toll on your roof, especially in northwestern Colorado. Heat damage is no joke when it comes to maintaining the integrity of your roof in.
All across Colorado, we can experience brutal heat and intense UV rays year round; and while your roof can withstand many weather extremes, a constant beating of sunshine can lead to heat damage, and can have killer effects on your roofing materials.
These are the elements will lead to heat damage over time:
Your roof is constantly exposed to UV rays, even on cloudy days, and this exposure increases considerably during the long summer days with all those extra hours of sunlight. UV rays dry out the oils in the materials your roof is made of. Wood can become bleached, weaken and crack, especially if it is untreated, and asphalt shingles can buckle and possibly split.
Your roof bears the brunt of the sun’s intensity and is exposed to a lot of heat during the summer. A roof without shade can reach temperatures of over 150 degrees on a day when the air temperature alone is 90. This expedites the damaging effect of the UV rays and can ultimately lead to other problems, such as condensation. For example, if your attic is not properly ventilated, heat will build up in it, raising the temperature inside your home and causing condensation problems.
Your roof can reach incredibly high temperatures during the day and tends to cool off rapidly once the sunsets. This causes the materials on your roof to expand and contract relatively quickly. This quick change can weaken the materials and they will lose some of their structural integrity over time. This is particularly true for metal, which can warp out of shape and lead to gaps appearing between metal elements of your roof and the rest of the structure.
Here are a few ways the UV rays, heat and thermal shock can create problems to your roof materials:
When exposed to relentless heat and sun, especially in the high Rockies, the shingles on your roof can start to experience decay. Newer shingles tend to hold up relatively well in the heat; it’s generally older roofs where the shingles start to show decay due to the sun. Decaying shingles will look deformed or rotted. They may be missing chunks or start to look like they’re crippling.
If you’re noticing that some of the shingles on your roof are starting to curl or bend upwards, it may be due to the intense heat or sun. Older shingles that are easily affected by prolonged heat or sunshine can show these effects. This type of warping will only get worse as time goes on, so it’s important to call in an expert to check on the status of your shingles.
Shingles on your roof may also start cracking when the sun or heat starts to get to them. As shingles start to curl, it creates tension, which causes a lot of strain that will often leads to cracking in the shingle. Shingle cracking should be repaired as soon as possible as cracked shingles will always lead to more roofing damage when left untreated.
The good news is that the damage caused by heat and other factors during summer is cumulative, meaning it builds up over time, and your roof isn’t going to crumble and turn to dust after one week of extra-warm weather. Knowing what to look for and keeping an eye out for any developing issues and dealing with them promptly will save you money in the long run.
