The summer season is winding down and to many people’s delight the temperatures are beginning to drop. Although you may be enjoying the cooler weather you might actually have an issue on your hands. Many states including Arizona, Utah, and Idaho experience extreme heat throughout the summer—with temperatures reaching above 100 degrees Fahrenheit. While you were relishing in the warmth, throwing barbecue parties, and suntanning near the pool, you probably weren’t worried too much about how the heat was affecting your roof.
Whether the effects were small or big, chances are that your roof was impacted in some way. Read on to understand how summer may have taken a toll on your roof and to learn about what CTI Contractors can do to resolve it.
3 Ways the Summer Heat Impacts Your Roof
The purpose of a roof is to protect you and the rest of your home from exterior influences (ie. rain, wind, heat, cold, etc). However, nothing is there to cover the roof to protect it as well. Because of that and the fact that it is the part of your home closest to the sun, your roof is vulnerable in the following ways:
1. UV Rays Cause Discoloration, Cracking, & Other Damaging Effects
The sun emits UV rays which are electromagnetic radiation that cause chemical and biological effects. If you’ve ever had a sunburn, then you’ve experienced that before. Yet, your skin isn’t the only thing that is being altered by the radiation. Your roof experiences its own version of sunburn, too.
Your roof’s materials have oils in them. When exposed to the power of the sun on a constant basis, those oils dry out. Your roof is more at risk of this happening during the summer because the days are longer compared to any other season. Here is what could happen in that case:
- Become discolored and look bleached.
- Weaken and become less durable.
- Start to crack.
- Buckle and cave in.
- Split and fall apart.
Excessive exposure to UV rays can wear down your roof, even if the materials are meant to be durable and long-lasting. To combat the long-term impact that radiation might have on your roof, make sure to have a professional inspect and make any necessary repairs to it during this fall season. After all, you don’t want to go into winter with a tarnished roof.
2. An Unshaded Roof Bakes Your House
Not everyone is fortunate to have a giant tree in their yard. Because trees provide shade, they’re able to keep roofs from overheating when the sun beats down on it. On a 90-degree day, the temperature of the surface of an unshaded roof can reach up to 160 degrees—which is hot enough to fry an egg on it if you really wanted to. Imagine how much hotter it can get when the day’s temperature is in the hundreds!
Such extreme temperatures speed up the UV rays’ damaging effect. However, it can also have an impact on your home’s interior. If your attic isn’t properly ventilated, for example, the roof’s temperatures will increase and consequently raise the indoor temperature with it. This can lead to condensation issues that result in water damage and mold growth. It can also potentially increase the cost of your utilities.
To help decrease your roof’s temperature for future summer seasons, you could spray it down with a cool coating that will lower the temperature by 60 to 70 degrees. Another option is to have your roof replaced with one that is made of different material. If your current roof has asphalt shingles, then it spent all summer absorbing heat rather than retracting it. A metal roof, however, is reflective and doesn’t allow nearly as much heat to seep into the home.
3. Thermal Shock Weakens the Structure
The term “thermal shock” refers to what happens when the temperatures vary significantly from day to night. When the temperature is hot your roof’s materials are likely to expand. Alternatively, they tend to contract when the temperatures get colder. If this process happens back and forth too quickly, the result will be shock.
If you take a look at your roof and see that it looks as if it has been warped out of shape, then shock and deterioration has probably settled in. Your roof’s joints may be cracked and separated. The flashings and seams could be tearing or separating as well.
During the summer months your roof is particularly susceptible to thermal shock as the weather turns from extremely hot during the day to cool in the evening. This pattern is a pretty common occurrence in the states that we service in. If you think that your home has experienced the ill effects of thermal shock, don’t hesitate to take action by seeking out roofing repairs.
