Homeowners often wonder, what size hail will damage a roof? This is vital to understand, as not every storm brings roof damage. On the other hand, hail damage isn’t always visible to homeowners unfamiliar with roof repair.
Pea-sized and marble-sized hail don’t typically risk roof damage. However, anything more than 3/4” or a full inch in diameter risks damage to shingles, metal, and other materials. Also, hailstorms can mean clogged gutters and dented siding.
Note that this is just a quick explanation of potential hailstorm damage to your home’s roof. Knowing more about how hail affects roofing materials and other features around the home is vital! You can then know when to call a roof repair contractor near you. In turn, your home will be in good condition from the top down.
Not all hail damages roofs, as said. The size of hail that damages a roof depends on various factors. These include the type and condition of the roof, its material, and impact angle. In general,
larger hailstones are more likely to cause damage. However, even smaller hailstones can lead to damage under certain circumstances. This includes high winds and if the hail hits a surface straight-on. Note a few added guidelines for hailstone sizes and their potential impact on a roof:
Lastly, remember that wind speed and hailstone density both influence the severity of the damage. Roofs in good condition may withstand smaller hailstones without much damage. On the other hand, smaller hailstones can damage weaker or older roofs easily.
While not common, pea-sized hail risks roofing damage. This is especially true if the roof is already in poor condition and for certain materials. Check out what this means in added detail:
Different roofing materials have varying levels of resistance to hail damage. For instance, metal roofs are more likely to withstand pea-sized hail compared to asphalt shingles. Durable metal doesn’t dent or ding easily. On the other hand, even smaller hail can strip shingle granules or risk cracking the material.
An older or poorly maintained roof is more susceptible to hail damage. Older roofs might already suffer from small cracks and leaks. Also, roof materials tend to break down and degrade over time. In turn, even the smallest hail risks damage.
The angle at which hailstones strike the roof influences the extent of the damage. Hail that hits the roof straight-on is more likely to cause damage than hail that strikes at an angle. The roof’s slope also affects the angle of impact. Hail won’t hit with as much impact on a sloped roof than a flat surface!
Strong winds accompanying hail increase the force of impact. In turn, this risks more damage to your roof and other surfaces. Also, high winds can loosen shingles and other roofing materials. Consequently, hail can easily strike the roof’s underlayment and decking, risking damage.
In conclusion, note that it's essential to conduct a thorough inspection after any hailstorm. Look for dents, cracks, or granule loss on asphalt shingles. If you notice any issues, have a roofer assess the damage and make necessary roof repairs after the storm. Addressing minor damage promptly prevents more significant problems in the future.
If you live in an area prone to hailstorms, it’s helpful to consider a hail-resistant roof. Manufacturers design these to withstand the impact of hailstones and minimize damage.
Additionally, ask your roofer about products certified for impact resistance, such as those meeting the UL 2218 Class 4 impact rating. These ensure a strong resistance against hail and other damaging elements.
Generally speaking, metal roofs last far longer than asphalt shingles. If you install and maintain it properly, a metal roof can last 40 to 70 years or more. Also, metal resists damage common with other materials including rot, insect damage, and fire. A metal roof also stands up well in harsh weather, including heavy rain, snow, and hail.
On the other hand, asphalt roof shingles are more affordable. High-quality asphalt shingles usually last around 20 to 30 years, while lower-grade shingles may last less than 20 years. Weather, storm damage, and other factors all affect asphalt roof lifespans. Note what else can affect your roof’s longevity in more detail:
Remember, addressing damage quickly after a hail storm can prevent leaks and more extensive repairs down the road, so don't delay in taking action.
