In Michigan, our weather can be wildly diverse, and sudden hailstorms are a frequent reality for homeowners in Fraser, MI, and across Southeast Michigan. While fascinating to watch, these storms pose a severe threat to your home’s first line of defense: your roof.
To help you understand the impact of these storms, we have broken down everything you need to know about hail damage. Each section below is designed to quickly answer your most pressing questions so you know exactly what to look for after the skies clear.
What makes Michigan hailstorms so damaging to residential roofs?
Michigan’s rapidly changing weather patterns generate severe hailstorms that cause direct physical impact damage to roofing materials, leading to protective granule loss, bruised asphalt shingles, and eventually, structural water leaks.
In South East Michigan, particularly around Macomb County and Fraser, MI, spring and summer storm fronts frequently bring hail. When a hailstone strikes an asphalt shingle, the force of the impact knocks away the protective ceramic granules. These granules are designed to block UV rays and shed water. Once they are gone, the exposed asphalt mat bakes in the sun, becomes brittle, and eventually cracks, compromising the entire roofing system.
Pro Tip: After a severe storm in South East Michigan, do not assume your roof is fine just because you don’t see missing shingles. Hail damage is primarily an impact injury that weakens the roof over time rather than tearing it apart instantly.
How does the size of the hail affect the severity of roof damage?
The larger the hailstone, the more kinetic energy it carries, resulting in exponentially worse damage ranging from minor accelerated aging to immediate, deep structural fractures in the shingle mat.
Not all hail events require a total roof replacement, as the size of the ice dictates the severity of the impact:
- Pea-Sized (¼ inch): Rarely causes immediate leaks but can dislodge granules, slightly accelerating the roof’s aging process.
- Marble to Quarter-Sized (½ to ¾ inch): Often causes “bruising” on the shingles, knocking off significant amounts of granules and creating soft spots in the asphalt.
- Golf Ball-Sized (1.75 inches) and Larger: Causes catastrophic damage, including deep dents, shattered fiberglass mats, and heavily cracked shingles that require immediate professional attention.
Pro Tip: If you see quarter-sized hail or larger accumulating on your lawn or driveway, it is almost mathematically certain that your roof has sustained measurable impact damage.
What are the early signs of hail damage you can spot from the ground?
Homeowners can identify potential hail damage from the ground by looking for heavy granule accumulation at the base of downspouts, dented soft metals like gutters and AC units, and visible “spatter marks” on driveways or siding.
Safety should always come first, and you do not need to climb a ladder to look for clues. Hail impacts the entire property, not just the shingles. If a storm was severe enough to damage your roof, it will leave secondary indicators. Dented aluminum gutters, dinged window wraps, damaged siding, and pockmarks on the fins of your outdoor air conditioning unit are all strong evidence that the roof took a beating as well.
Pro Tip: Check the splash blocks at the bottom of your gutter downspouts immediately after a storm. A sudden, thick pile of dark shingle granules is the most reliable ground-level indicator that your roof’s protective layer has been compromised.
How does hail damage differ from normal roof wear and tear?
Hail damage appears as localized, random circular bruises or fractures with fresh, black asphalt exposed, whereas normal wear and tear presents as uniform, widespread granule loss and gradual curling of the shingle edges.
As a roof ages naturally, the sun and rain slowly wash away granules over decades. This aging is generally even across the entire surface. Hail damage, however, is an acute event. It creates distinct “impact craters.” If you look closely at a hail hit, you will often see a dark, circular spot where the granules have been violently pushed into the asphalt mat or knocked away entirely, leaving a fresh wound on the shingle.
Pro Tip: Insurance companies frequently try to classify roof damage as “wear and tear” to avoid paying claims. Knowing the difference between an acute hail bruise and general aging is critical when discussing the condition of your roof with an adjuster.
What happens if you ignore hail damage on your roof?
Ignoring hail damage allows UV rays to degrade the exposed asphalt, leading to thermal cracking, water infiltration, secondary wood rot in the decking, and eventually, toxic mold growth inside the home.
A bruised shingle rarely leaks the day after the storm. Instead, it creates a ticking time bomb. Without the protective granules, the sun “bakes” the exposed asphalt. Over the next 6 to 12 months, the shingle becomes brittle and cracks as it expands and contracts with Michigan’s temperature swings. Once the crack penetrates the fiberglass mat, rainwater bypasses the waterproofing and begins rotting the wooden roof decking and soaking your attic insulation.
Pro Tip: Delaying an inspection can cost you your insurance coverage. Most insurance policies have a strict statute of limitations for filing a weather-related claim, and waiting until the roof actually leaks may result in a denied claim due to a failure to mitigate the damage.
What does a professional hail damage inspection involve?
A professional inspection involves a trained expert physically examining the roof to document granule loss, identify microscopic fractures in the shingle mat, check soft metals for dents, and assess the overall integrity of the waterproofing system.
While ground-level signs are helpful, a trained eye is required to assess the true condition of the shingles. Professionals from Premier Roofing know exactly what major insurance carriers require for proof of loss. They will safely scale the roof, use chalk to mark and measure a “test square” (usually 10×10 feet) to count the number of hail hits, and take high-resolution macro photographs of the bruised asphalt to document the exact severity of the storm’s impact.
Pro Tip: Never accept a “drive-by” or strictly drone-based inspection. True hail bruising can often only be felt by hand (checking for a spongy depression in the shingle) and must be documented up close.
Your Next Step: Don’t Wait for the Leak
If a recent storm in Fraser or South East Michigan has left you wondering whether your roof sustained damage, the worst thing you can do is wait for a water stain to appear on your ceiling.
Once you have spotted the ground-level signs of hail impact, your next step is to get a documented, professional evaluation.
