What Does Hail Damage Look Like On A Roof: Signs To Watch For

Encountering hail damage on your roof after a severe storm can be a homeowner’s nightmare. Hailstorms cause billions of dollars in property damage annually. This article will guide you through identifying the telltale signs of hail damage on your roof.

Trust us, a timely inspection can prevent further costly repairs. Hail damage usually doesn’t lead to roof leaks for at least 6 months but once the protective granules are gone, the bottom layer of the singles (fiber mat) begins to deteriorate. If you have 10+ hail strikes in a test square, your insurance will likely replace your roof.

The Effects of Hail Damage On Roofs in St. Louis


Roofing materials like asphalt shingles suffer granule loss, dents, cracks, and bruising from hailstone impacts. Metal roofs endure dents and punctures. If we look at the storm that occurred Mar 15, 2024 in St. Charles, MO where baseball-sized hail hit the area, it becomes clear that weather in our area can be severe.

Hail size of 1″ or larger can severely compromise a roof’s integrity, leading to leaks and interior water damage. Left unrepaired, hail-damaged roofs deteriorate rapidly, allowing water to reach the plywood within a year.

Dented gutters, downspouts, and siding signal widespread exterior destruction requiring comprehensive repairs or replacement to prevent water infiltration issues. Ignoring hail damage exacerbates problems necessitating more extensive and expensive fixes down the line.

How do you know if your roof or exterior has hail damage?

To determine if your roof or exterior has hail damage, you can perform a simple ground inspection by yourself. You may be able to see dark circular or oval marks on the shingles. You can also look for little dings and divots on soft metal surfaces such as gutter downspouts and vents. Use the side of standard chalk, you can wipe across a surface, areas that don’t get colored could be divots from hail.

Additionally, check for cracked or broken gutter guards, as these are also indications of hail damage. From on the roof – visible signs like dislodged granules, bruised shingles or siding, dented gutters, and damaged chimneys reveal hail’s destructive path.

Signs of Hail Damage On Asphalt and Composition Shingles

Hail storms wreak havoc on asphalt and composition shingles—discoloration spots, dents, cracked shingles, and granule loss signal the battle scars. Damaged gutters, flashing, and downspouts raise the red flag too..but there’s more to uncover.

Discoloration Spots: Impact Marks & Bruised Shingles

Hailstones leave visible impact marks on shingles. These discolored indentations signify the size and severity of hail. Inspect your roof closely – discolored spots signal underlying damage to shingles from hail impacts.

Bruised or cracked shingles provide clear evidence of hail storms.

Granule Loss

Granule loss is could be a telltale sign of hail damage on asphalt and composition shingles. Different hailstone sizes can cause varying degrees of granule loss. 

Hailstorms batter roofing materials, bruising shingle underlayments. This bruising causes granules to loosen and fall off, requiring replacement. Neglecting granule loss accelerates roof aging, compromising its protective capabilities against weather elements.

Exposed Fiberglass Mat

One obvious sign of hail damage on asphalt and composition shingles is an exposed fiberglass mat. This mat lies beneath the shingle’s granule surface—when hail impacts dislodge granules, the fiberglass underneath becomes visible.

Even relatively small hailstones can fracture this critical underlayment, compromising the roof’s integrity. Homeowners should inspect for this type of damage after severe storms, as an exposed fiberglass mat indicates a need for prompt repairs or replacement to prevent further deterioration.

Varying hail sizes create distinct patterns of bruising on the fiberglass mat. Smaller hailstones may only cause surface crazing, while larger projectiles can punch through entirely.

Damaged Gutters, Flashing and Downspouts

Hail can wreak havoc on gutters, flashing, and downspouts—telltale signs of roof damage. Impact dents indicate the severity of the storm. Larger hailstones, around 1¾ – 2 inches, penetrate softer roof areas, damaging gutters.

Gutters’ condition reflects the roof’s state—dented gutters signal potential shingle damage. Inspecting them closely reveals hail’s force, aiding in documenting evidence for insurance claims.

Can Hail Damage a Metal Roof?

Hail can absolutely damage metal roofs. Even relatively small hailstones, less than an inch in diameter, possess sufficient force to dent or puncture metal roofing materials. Larger hailstones exacerbate these risks—potentially ripping through panels or dislodging fasteners.

In 2022 alone, over 4,400 severe hail reports led to billions in property damage across the nation. Hail storms wreak havoc—pummeling aluminum, steel, and other metal roofing systems.

What Size Hail Can Damage Roof Shingles?

Hail can wreak havoc on your roof, causing costly damage. Even small hailstones—1/2″ or less—can leave unsightly dents and discoloration on asphalt shingles. For more substantial harm, watch out for hail measuring 3/4″ to 1″ in diameter—this size can crack shingles, causing granule loss and exposing the fiberglass mat beneath.


Hail as small as 1/2 inch can cause cosmetic damage to asphalt shingles. Granule loss, discoloration spots, and bruised shingles indicate minor impact marks. While unsightly, these typically don’t require immediate roof replacement.

1” Hail Damage

1-inch hail, roughly the size of a quarter, packs enough force to dislodge granules from asphalt shingles. You should certainly call a roofing company for inspection after this kind of weather event even if you don’t visibly see the damage from the ground.

1.5 – 2” Golf Ball Sized Hail Damage

Hail between 1.5 – 2 inches poses a significant threat to roofs. Golf ball-sized hail can penetrate asphalt shingles, dislodging granules and exposing the shingle’s mat. It may also dent and crack shingles, compromising their waterproofing integrity.

Metal roofs aren’t immune either—hailstones this size can dimple and pit surfaces, leading to leaks and accelerated corrosion.

Homeowners should promptly inspect for circular dents, missing granules, and shingle fractures after a hailstorm involving golf ball-sized hail. Even minor impacts weaken shingles over time, allowing moisture intrusion and reducing the roof’s lifespan.

Baseball Sized Hail Damage

Hail exceeding 2″ in size, commonly referred to as baseball-sized, possesses immense destructive potential. Such massive hailstones can penetrate roofs, dent siding, shatter windows, and inflict significant structural damage.

Immediate inspection and repairs become imperative to mitigate further harm from subsequent storms.

Steps to Take After Identifying Hail Damage

If your home experiences a severe hail storm, acting promptly is crucial to mitigate further damage – inspect your roof and exterior thoroughly, documenting any signs of impact. Hire a reputable roofing contractor to conduct a comprehensive assessment, ensuring a proper insurance claim and timely repairs.

Neglecting hail damage can lead to costly consequences down the line.

Hire a professional roofing contractor

After identifying hail damage, hiring a professional roofing contractor like American Roofing ensures proper inspection and repair. Reputable contractors understand insurance claims, document damage thoroughly, and work with insurers for full payment.

Experienced roofers assess hail’s impact on shingles, flashing, and gutters, ensuring comprehensive repairs safeguard your home.

Attempting DIY hail damage repairs risks voiding warranties and insurance coverage. Professionals have workers’ compensation and liability insurance, protecting you from legal issues.

Conduct a thorough inspection of the attic

Conducting a thorough attic inspection is crucial after a hailstorm. Closely examine the attic’s interior for signs of water intrusionstaining on the roof deck, or daylight peeking through.

These indicators signal potential hail damage, necessitating prompt repairs to prevent further issues like mold growth or structural deterioration.

How to Repair Hail Damage and Get Full Payment from Insurance

Resolving hail damage swiftly protects your home’s value—contacting your insurance provider and collaborating with a reputable roofing contractor ensures comprehensive repairs and fair compensation.

Contacting your insurance company

1) Don’t call the insurance company first. It may become a claim on your record even if they do not decide to cover the damage. Remember that insurance is only willing to cover damage that happens suddenly and unexpectedly.

2) Work closely with a roofing company who can document the incident thoroughly with photos and videos, detailing the extent of the damage, and they can let you know if insurance would likely approve your claim. A reputable roofing contractor can assist in this whole process, advocating for your interests and ensuring fair compensation from the insurance company.

Working with a reputable storm damage expert

Create a comprehensive record with dates, times, and descriptions of the damage. If you happen to have forgotten the date of the storm, you can always research past hail storms at

Homeowners should enlist a reputable roofing contractor experienced in storm damage assessments to conduct a thorough inspection.

Repair options for hail damage

Hail damage repair options encompass a spectrum, from minor shingle replacements to complete roof overhauls. Asphalt shingle repairs involve replacing dented, cracked, or granule-depleted shingles.

For more extensive damage, an overlay — installing new shingles over existing ones — provides a cost-effective solution. However, if the damage penetrates the underlayment or decking, a full roof replacement becomes necessary, addressing underlying issues for long-term protection.

Metal roofs can withstand minor hail impacts without significant damage. But larger hailstones may cause denting, necessitating panel replacements or resurfacing. Timely repairs prevent leaks, water infiltration, and costlier consequences down the line.
