Is Your Roof Adequately Protected From The Sun?

One thing that your roof will be exposed to no matter what is the sun's rays. An excessive amount of sunlight can cause your roof to become very hot and can also be damaged by radiation. There are several things you'll need to watch out for.


Your roof might begin to fade when exposed to moisture with a process known as "fading." Bleaching is more likely to occur with roofs that are darker. Lighter roofs can be a better option in hotter climates because they don't fade as much and can also reflect sunlight better.

Expansion and Contraction

The sun can cause your roof to expand and contract. This can result in your roof becoming damaged and is especially common with roof tiles since these types of tiles are made with oils that are meant to allow the tiles to expand and contract. However, your heated roof will cause the oils to evaporate. 

Thin and Brittle Shingles and Tiles

UV rays are invisible but can cause damage to a roof over time. Roof tiles and shingles eventually break down. Shingles might warp and may become less effective at protecting your roof from the rain. Depending on the type of roof you have, some sections of your roof can become thin and brittle. This can make the roof more vulnerable to damage caused by strong winds and flying debris.

A Worn Out Protective Coating

Your roof needs a protective coating to make sure that it is shielded from the elements. However, UV radiation can cause the protective coating to dry out. Then, your roof will not be protected from harsh elements. For example, the coating might crack and peel leaving an opportunity for moisture to cause damage to your roof.

If you aren't sure if your roof is being damaged by sunlight, make sure to have it inspected by a roofing contractor. There are telltale signs that a roof is being damaged by heat and radiation. There might be cracked or missing shingles, water leaks, and rotting materials. However, a roofing contractor will be able to determine the full extent of the damage and will then recommend the appropriate action to be taken.

If your roof needs to be replaced, the roofing contractor will recommend durable materials that will be able to take a beating and will also recommend a protective coating that will be able to shield your home from the hot sun.
