Hail damage can dislodge the protective mineral granules of asphalt shingle, producing areas of exposed asphalt shingle substrate. Hail can cause the shingle to crack or spit. Asphalt shingle blisters are raised bumps or protrusions in shingle surface, either closed blisters or open ones showing a small black pit or crater when the protective mineral granules have been lost from the peak of the blister. Homes with wood shingles can split or be punctured. Any damage that may happen only increases as the size of the hail increases. The older the roof, the more damage occurs since the granules are less securely attached to the surface of the shingles. A hail damaged roof will have a reduced “roof life”, resulting in earlier weathering or cracking. As time goes on, it will become increasingly more difficult to make the distinction between hail versus wear. It will be easier to resolve the issues surrounding your hail damaged roof if you take care of it now, rather than waiting down the road to do so.
The impact of hailstones on a roof depends on at least these factors:
- Size: The size of the hailstone
- Mass: Some assumptions about the typical mass of a hailstone (ice or ice with some water coating)
- Wind: The effect of wind on the object’s velocity
- Falling height or distance (we assume the distance is sufficient to reach terminal velocity before considering wind effects)
- Mechanics: The assumption that all of the physical energy is converted to kinetic energy as the object strikes the roof
- The pre-existing condition of the roof surfaces, age, existing damage or wear fragility
- The roof slope and angle of presentation of the roof slope to the direction of wind-driven hailstones
A 1 cm hailstone has a theoretical terminal velocity of about 20 mph (9 meters/second). Larger hailstones have a much higher terminal velocity. And a ten-gram hailstone falling from 10 km (this distance is probably more than enough) has a terminal velocity of about 15 meters per second.
How To Detect Hail Damage
While you can not fully determine if your roof has hail damage from the ground there are some signs that a trained eye can point out and help determine if there may be more damage up top. The presence of one or more of these factors may indicate a situation where the homeowner needs a full roof replacement instead of a simple roof repair. If you suspect roofing damage from hail, call Statewide Roofing we will give you a free, honest and reliable roofing report for a roofing inspection.
It’s spring and after a heavy spring storm, many homeowners find themselves in need of hail damage repair on their roof. We recommend that you do not climb on the roof if you are unsure at heights, unsteady on a ladder. The severity of hail damage to a roof depends on several factors, including the type of roofing materials, the age of roofing materials, roof slope, quality of construction. Hail Size, Density, Shape and velocity and angle of its fall.
If you see these signs call statewide for a roofing inspection:
- Missing shingles. High winds can peel the shingles completely off the roof, exposing the roof’s underlayment and requiring immediate replacement.
- Lifted and curling shingles. High winds can break the seal of the shingles and make the roof penetrable to wind-driven rain.
- Dents or pockmarks in shingles. Driving hail can scrape off the protective granules on the shingles that are necessary to protect a roof from rain and sun damage.
- Water stains on the ceiling or walls, caused by seepage from the damaged roof
- Cracked or peeling paint, caused by moisture in the walls
- Visible water in the attic, on the beams, insulation or finished areas
- Mold or mildew growth, especially in attics or other dark enclosed areas
- Excessive energy bills, caused by escaping cool or heated air
- dented metal vents, chimneys, skylights, and other roofing features
Hail Damaged Commercial Roofing
Following a major storm, a potentially serious, yet difficult-to-detect. Often following a hail storm, business owners and building managers don’t even realize their property has suffered damage. As a result, a hail damage commercial roof insurance claim may not be filed promptly. It is prudent to investigate your property for hail damage soon after a hail storm. Check to see if trees or flowers on the property are damaged, if cars parked in the open are dented, or if any of the building windows are cracked. Window and door screens, siding, and air conditioners should also be closely inspected. Roofing normally sustains the most costly hail damage, although hail damage to asphalt shingle roofs or commercial flat roofs is often not immediately recognized. It may take up to three years after a hailstorm for a roof to leak. For commercial flat roofs, unless the hail is quite large (baseball size or more), it may be even harder to detect the damage until much later, which can have an impact on any hail damage commercial roof insurance claim. We recommend a thorough inspection after any severe weather event.
Do you need to get Hail Damaged Fixed
Hail damage is not always an immediate threat to your roof so you may think it can just wait. Hail Damage can drastically shorten the lifetime of your roof. It may cause your roof to fail in latter storms. Insurance companies often have time limits where a homeowner can claim the hail damage on their roof.
