What Does Hail Damage Look Like on a Roof?

Colorado is no stranger to hailstorms. In fact, the Front Range is located in what meteorologists call “Hail Alley”, a region stretching from Wyoming through Colorado down into Texas. Hail is one of the most costly weather events in these regions, and Colorado consistently ranks among the top three states for hail-related claims and roof hail repair every year.

If you’re a homeowner in Colorado, chances are you’ll face hail damage at some point. But the real challenge is knowing what hail damage looks like on a roof, and whether what you see is cosmetic or a sign of deeper trouble.

Why Identifying Hail Damage Matters

Hail damage isn’t always obvious. While large hailstones can leave visible dents and cracks, smaller hail can cause subtle bruising and granule loss that weaken your roof over time. Left unaddressed, these issues can lead to:

• Leaks and water intrusion
• Mold or insulation damage
• Reduced energy efficiency
• Shortened roof lifespan
• Denied insurance claims if not reported promptly

That’s why it’s so important to know the signs and to schedule a professional roof inspection after a hailstorm.

How Hail Actually Causes Roof Damage

Hail can cause roof damage in several ways, depending on the size, density, and speed of the hailstones, as well as the type and age of your roofing materials.

When hailstones strike your roof, the impact creates a sudden force that can compress, crack, or weaken the surface. On asphalt shingles, this often knocks away protective granules and can bruise the underlying mat. These bruised areas may not always be visible right away, but they can lead to missing shingles and reduce the shingles’ ability to protect against water and UV exposure.

On metal surfaces, hail typically leaves dents or dimples. While some of this damage may appear minor, repeated impacts can affect seams, fasteners, and protective coatings.

Flat roofing systems can experience punctures, surface weakening, or depressions that allow water to collect. Over time, these areas can lead to leaks or membrane failure.

Even smaller hailstones can cause cumulative damage. The effects may not show up immediately, but can shorten the lifespan of your roof and increase the risk of future problems. A professional inspection helps identify both visible and hidden damage before it worsens.

1. Hail Damage on Asphalt Shingle Roofs

Asphalt shingles are the most common roofing material in Colorado, and one of the most vulnerable to hail. Signs of roof hail damage include:

• Bruising or soft spots: When you press on the shingle, it may feel soft, like a bruise on fruit. This indicates underlying damage.
• Granule loss: Shingles are coated with protective granules. Hail impact often knocks these loose, leaving dark, shiny, or bald spots.
• Cracks or splits: Large hail can crack shingles completely, exposing the underlayment beneath.
• Random damage patterns: Unlike wear and tear, hail damage is usually scattered across the roof with no uniform pattern.

If you see bald patches in your gutters or around the base of your downspouts, that’s often a sign of hail knocking granules loose.

2. Hail Damage on Metal Roofs

Metal roofing is more resistant to hail than shingles, but it’s not immune. Look for:

• Dents or dimples: Most often on flatter sections or softer metals like aluminum.
• Damaged coatings: Impact may scratch or remove protective paint or finish, making the roof more vulnerable to rust.
• Seam or flashing damage: Even if the panels hold up, the seams, flashing, or fasteners may be affected.

While dents are often cosmetic, they can reduce curb appeal and sometimes affect resale value. In more severe cases, impacts can damage the roof’s structural integrity.

3. Hail Damage on Flat Roof Systems (TPO, EPDM, Modified Bitumen)

Commercial properties often use flat roofing systems, which can also be damaged by hail. Warning signs include:

• Punctures or tears in the membrane
• Blisters or bubbles from impact weakening the surface
• Indentations or depressions that collect water (ponding)
• Damage to rooftop equipment like HVAC units, vents, or skylights

Since these roofs are usually harder to inspect from the ground, professional evaluation is essential after a storm.

4. Collateral Signs of Hail Damage

Sometimes, the roof isn’t the easiest place to spot hail damage. Look for “collateral” damage on other parts of your property:

• Dents on gutters, downspouts, or siding
• Holes in window screens
• Damaged paint on decks or fences
• Dents on vehicles parked outside

If you see these signs, there’s a good chance your roof has also been impacted.

Cosmetic vs. Functional Hail Damage

Not all hail damage affects performance. Insurance companies often distinguish between cosmetic damage (like small dents in a metal roof that don’t affect function) and functional damage (which compromises the roof’s ability to shed water and protect your home).

Cosmetic Damage:

• Dents that don’t break through material
• Surface scratches

Functional Damage:

• Cracked, broken, or punctured shingles/membranes
• Exposed underlayment or decking
• Significant granule loss leading to leaks

If functional damage is found, it’s usually covered by insurance.

How Big Does Hail Need to Be to Damage a Roof?

• ¾ inch hail (about the size of a penny) can dislodge granules from shingles.
• 1 inch hail (quarter-sized) can crack or bruise shingles.
• 1.5 inch hail and larger can break shingles, dent metal, and damage flat roof membranes.

Colorado often sees hail over 1 inch in diameter, meaning most hail storms pose at least some risk to your roof.

What to Do If You Suspect Hail Damage

If you think your roof may have sustained damaged in a storm, here are the steps to take:

1. Stay safe – Avoid climbing onto the roof yourself.
2. Document the storm – Take photos of hailstones and visible property damage.
3. Check for collateral signs – Look at gutters, siding, and outdoor fixtures.
4. Schedule a professional inspection – Roofing contractors are trained to spot hidden damage.
5. Contact your insurance company – If damage is confirmed, start your claim quickly to avoid missing deadlines.
