What Weather Has the Biggest Impact on Your Roof?

What Weather Has the Biggest Impact on Your Roof? austin roofing companyA home’s roof is a critical structural component. It protects the occupants and contents of the house from the elements by shielding them from the sun, rain, wind, and hail, which are the same things that commonly inflict roof damage. However, because roofing materials are supposed to last for many years, many people fail to consider the harsh conditions that their roofs endure every day.

How Can the Sun Damage a Roof?

The sun is the source of two things that can potentially inflict roof damage: ultraviolet radiation and heat. UV rays can leave asphalt shingles dry and brittle, making them more susceptible to damage from other sources. Excessive heat can cause some materials to expand, potentially leading to loose or dislodged fasteners or cracking the material. If the hot weather is combined with high humidity levels, moisture can collect in the attic space, and this can lead to an interior leak or mold infestation.

How Does Rain Damage a Roof?

Many homeowners wonder how a component that is designed to shield the interior of their home from rain can be damaged by it. In Central Texas, thunderstorms are far from rare, and they often produce torrential downpours. All that water cascading down your roof can inflict damage over time, but the damage can occur faster and be more extensive if the water finds a weak spot. If the water pools and backs up around your flashing or roof edges, your decking materials can be damaged, and a roof leak is likely to occur.

How Does Wind Inflict Damage on a Roof?

Although many people think of tornadoes when they think of roof damage caused by wind, straight-line winds typically damage more Texas homes than tornadoes during a typical year. Strong winds can remove, crack, or loosen asphalt shingles. High wind can snap a tree branch that falls on the roof; if the branch hangs low over the roof, the wind can cause it to scrape the granules off your asphalt shingles even if the branch does not break. High, prolonged winds can cause metal panels, tiles, or shingles to shift out of alignment, leaving an area prone to water penetration.

How Does Hail Damage a Roof?

Central Texas is famous for its hailstorms. Most Texans have seen more than one video of hailstones the size of softballs, and such a large, hard chunk of ice can break asphalt shingles or dent metal roofing. However, hail does not have to be massive to damage your roof. Smaller hailstones can remove the granules from asphalt shingles in just a single storm. Over the years, your shingles may endure multiple hailstorms, resulting in significant degranulation even if none of the storms produced large hail. Once the granules are lost, the asphalt in your shingles will dry out faster, turn brittle, and become more susceptible to damage from wind, hail, and rain.
