If you suspect hail damage to a commercial or residential roof then you will want to inspect the roof following a hail storm. But, before you grab your ladder to inspect your roof for hail damage, there are a few things you should know.
Regular Roof Inspections: If you are willing to venture onto your roof every spring, for an annual roof inspection, you should look for any changes since the previous inspection and detect any potential issues before they become serious.
Be Careful: If you are not comfortable with climbing onto your roof for any reason you should not hesitate to call a roofing professional. The investment is well worth the time and will give you an accurate assessment of your roof’s condition.
1 Inch – 2 Inch: If the hail size is between 1 and 2 inches, or between a quarter and egg size, the hail damage should be more easily found on the asphalt shingles themselves, as well as any soft metal on the roof.
Greater Than 2 Inches: Hail greater than 2 inches will usually create some level of hail damage, especially to an asphalt roof. If this is the case, contact your preferred roofing contractor for a full assessment of the damages and notify the your insurance company.
There are three main signs that indicate a hail damaged roof, which include missing granules, bruising and circular cracking. With a basic understanding of each, it will help you to accurately identify the severity any hail damage.
Missing Granules: Check for missing granules that have exposed the substrate, or the black layer underneath them. The An exposed substrate should look fresh, or and not as if it has been exposed to the sun for an extended period of time. This will indicate new hail damage rather than a preexisting condition.
Bruising: Another indicator of hail damage is to run your hand over an individual shingle and feel for dimples or indentations. You should also press your thumb against the any indentations found and note if there is a soft spongy feel, like a bruised tomato. This bruising may be hidden, but will cause the shingle to fail prematurely over time.
Circular Cracking: Larger hailstones can cause circular cracking around the hit itself in a half-moon or full circle shape. This sort of cracking indicates a shingle that has been damaged through to the fiberglass matting, making it highly susceptible to water penetration.
