Can hail damage a metal roof? Homeowners in California are increasingly considering metal roofs for the added durability, energy-efficiency and design versatility that they provide; however, metal roofs are not immune to the elements and can be damaged by hail. If you live in a region with frequent hail activity, it is important to understand the potential of metal roofs to withstand it – this article will provide some insight into the durability of metal roofs when it comes to hail damage.
What is Hail?
Hail is defined as frozen rain that comes down in the form of solid ice pellets, usually accompanied by a thunderstorm. The size of the hail can vary significantly, up to several inches in diameter depending on the intensity of the storm. Additionally, hail can achieve speeds of over 100 miles an hour, making it a powerful force of nature.
Can Hail Damage a Metal Roof?
When hail comes pelting down, metal roofs are not completely immune from damage. Hail is capable of denting metal roofs, causing holes, and can even break through the protective coating that is used to keep the metal panels sealed. The severity of the damage will depend on the size, speed, and type of metal roof that is damaged by the hail.
Impact Resistance
Metal roofing is typically available with Different levels of impact resistance, depending on the manufacturer and the type of roofing that you purchase. Most roofing manufacturers grade the impact resistance of their roofing systems using an impact-resistance rating system, which measures the impact resistance of a roofing system or panel when struck by hail.
Coating and Damage Prevention
The coating or sealant that is used on metal roofs is an important factor in protecting against hail damage. There are specialized coatings that are specifically designed to help protect the underside of the metal panel from damage caused by hail; however, it is important to note that these coatings do not make metal roofs totally hail-resistant. Additionally, asphalt-based shingles are not designed to protect against hail damage, however, they may offer some protection against damage.
Style and Design
The style and design of the metal roofing system also play a factor in determining its ability to withstand hail damage. Metal roofs with a high amount of curves, such as standing seam and corrugated roofs, can be more resistant to hail damage than flat roofs. Additionally, the thicker the metal, the better the protection it can offer against hail, as the thicker metal will be able to absorb more of the energy from the hail, preventing it from becoming damaged.
Additional Protective Measures
In addition to choosing a metal roofing system with a high impact-resistance rating and coating, homeowners in California can also take extra steps to help reduce the risk of hail damage. Having a professional inspect and maintain the roof annually is important for ensuring the roof is in good condition and any potential hail damage is addressed promptly before it becomes a major problem.
