It is unusual to think in how seasons can affect you roof. It shouldn’t be that way.
Winter is the season that causes major damages in everything, including roofs.
But we can´t forget the roof problems derivative from strong summer seasons.
Among these problems, we can include: damage produced by summer storms and wind, materials degradation, damage caused by U.V. sunlight, and temperature fluctuations.
Let´s take a look at the impact due to hot time on roofs.
• Exposure to U.V. rays
UV rays from the sun cause the roof to age and decay, and it happens all the time, even on cloudy days.
But this effect is especially stronger during hot summer days.
These rays cause that wood bleaches, become wake and crack, evaporate oils in your roofing material, and shingles split.
• How heat affects roofs.
Dark color on roofs absorbs heat, and can reach temperatures as high as 160 F regular day of 90 F.
These high temperatures accelerate chemical reactions in the process, and break down faster your roofing and construction materials.
This problem can be solved by using proper attic ventilation.
In this way you can prevent damages from heating up your home’s interior and causing issues with condensation.
• Thermal Shock.
During the day, the roof can reach very high temperatures, and when de sun sets, it cools very quick causing expansion and contraction of the materials.
Due to this, the roof structure can weak as time passes, this can affect especially metal roofs, and could create gaps.
• Summer Storms.
In order to avoid serious damages in your roof due to wind summer storms, the best thing to do is checking items like these:
. Damages on the structure from the attic
. Damaged patches under the eaves
. Damaged shingles
. Gutter blockage
All these revisions should be done in spring, and take actions before summer arrives.
You have to be aware that damages caused on the roof during summer are cumulative, so you cannot see them until is too late.
All the effects due to heat, UV radiation and thermal shock take a long time to show up and are not visible before ten years or so.
To save money in long-term maintenance costs, you must be checking every time you can to find possible causes of roof damages.
At the same time, it is mandatory to take action as soon as possible when you see any kind of problem.
To avoid thermal problem due to summer heat, make sure that your attic has a good ventilation
By doing this, the roof will last much longer and you will save a lot of money in repairs or new installing
The best way to maintain a roof in good shape is taking care of repairs as quickly as possible, you must inspect your roof annually.
Other ways how summer heat can damage your roof.
Increased exposure to heat and sunlight in summer cause that asphalt shingles curl and erode.
This makes underlying roofing material exposed to rain and sun rays, and consequently your roof will be damaged when rain comes.
Despite this is a big problem especially for old roofs, the best way to protect yourself from expenses, is to have a checking periodical routine.
Roof Deck Rotting
One of the biggest problems in roofs is humidity, especially when it rains in the summer.
This humidity causes that the roof deck, which is the base of your roof, begins to rot.
This can lead to greater damages on your roof caused by water or heat that can make weaker all your roof
Cracking and Warping Shingles
When a roof starts damaging, the first sign is the shingles crack and warp.
During hot summers, roof temperature can reach more than 120 F., and this is really high.
This condition inevitably leads to the roof damage, shingles crack, curl or warp, and finally, the roof will need a complete change.
The message is: you must repair any crack, warp or curl shingles as soon as they are detected, this will save you a lot of money.

The most important thing is doing a regular maintenance, checking it at least once in a year, and fix any damage that appear.
This is important in summer; when your roof can get damage, so you must be sure it is in good condition to face this season.

Change the roof from asphalt to another material much cooler and reflective.
To protect the roof from thermal chock, apply periodic acrylic coatings.
