Hail damage is often almost invisible on metal roofs. The size of it can vary and be completely random. Even if you don’t see any breaks and dips on the shingles, you may still have hail damage. If you find indentations in siding, gutters, or chimney caps, it is worth taking a second look at your roof. Not having visible signs of hail doesn’t mean you don’t have it.
Even though you have a metal roof, when a hail strikes with force it can damage the metal and reduce the lifetime of your roof. When a metal roof is hit by hail, the galvanized coating is cracked which leads to corrosion and the destruction of the roof. It will also form dents that will collect water. Sooner or later, it will lead to rust.
What Is Hail?
Hail is precipitation that can appear when air updrafts and carry raindrops into the clouds where they freeze. They form tiny crystals or specs of dust. Then these frozen particles drop down the clouds and get caught in a new updraft. They slowly grow larger until gravity no longer let them move upwards. This is when hail falls on the ground and can damage your roof.
You can tell whether you have hail damage by looking for damage in gutter screens and downspouts. Metal roofs often have significant hail damage up top, so the gutters will have some visible damage as well. You should also look for damage to casings and siding. These are the places where you can easily spot it. Look also at metal fascia and other metal surfaces for signs of damage.
If hail does cause damage, this feature is covered by metal roofing manufacturers. If your roof has suffered severe damage, consider getting help from professionals specializing in this field. Equipped with resources and knowledge, you will have a professional eye to spot all issues with your roof.
