Top 5 Types of Weather That Damage Your Roof

0
The roof on your home is the main barrier between you and bad weather. A roof made with good quality materials and installed by professionals can last 20 years or more without any problems. However, certain weather conditions can damage your roof to the point it needs to be replaced. Let’s look at the top five types of weather that could cause extensive roof damage.

High Winds

High winds can be very dangerous for your roof. The winds can carry branches, twigs, and other debris that can puncture the roof itself. Even worse, it can lift shingles and tiles up, blowing them completely off the roof.

Even if the winds don’t tear the shingles off, they can cause a lot of damage. When a shingle gets lifted off the roof, it can pull and tear away from the nails holding it on. So, even if you don’t have missing shingles, you may have tears and holes everywhere.

Hail

Hail is essentially fast moving lumps of ice. Small pieces of hail don’t usually cause a lot of damage. As the hailstone increases in size, however, the more damage it can cause. Large hailstones can cause dents in the surface of your roof. At certain angles, you may find torn or missing shingles.

One of the problems with hail is that it can cause damage that isn’t always visible to the naked eye. When the hail hits the surface of an asphalt shingle, it can knock the granules loose. Those granules protect the shingle from the sun’s heat and UV rays. Without those granules, the roof can start deteriorating quickly.

Inspect your roof as soon as possible after a hail storm.

Heavy Rain

A heavy rain storm will dump a lot of water in a short amount of time. Because the water is coming down quickly, it will find every potential flaw in your roof. You may experience leaks after a heavy rain and not know where the water is coming in.

Even if there are no leaks, heavy rainfall over a long period of time can lead to material rotting. Roofs are designed to dry out between rain storms. Rain also settles into the lowest point of flat roofs, leading to moisture damage and eventual rot.

Snow and Ice

Snow fall itself rarely causes a problem with the roof. The problem starts when the snow and ice starts to melt. The water can refreeze when it hits the edge of the roof. This is called ice damming. As the water refreezes, it can back up under the roof shingles. This can lead to damage and rot to the underlying materials.

In time, you may start to see the edge of the roof sagging due to the rot. Or, you may start getting leaks at random spots where the ice damming has caused problems further up the roof. The leaks can multiply as the spring rains arrive to highlight the weak spots.

Heat

An extreme heat spell can actually cause more damage to your roof than winter snow or spring storms. The roofing materials will start to swell as the heat builds up. This can cause nails to pop loose or shingles to pull away from each other. When the shingles start to shrink, the damage can become more extensive. The heat can also cause materials to become brittle. This makes them vulnerable to rain and wind storms of the future.

The best defense against heat is adequate attic ventilation. This allows the roof to get some relief from the heat and helps prolong its life.

If you think weather has done damage to your roof, get a professional roofer out to take a look. The quicker you take action the faster you can contain and repair the damage. Unfortunately, the damage may be extensive enough to require a full roof replacement. In many cases, you may be able to file an insurance claim to cover at least part of the costs of replacement.
