Damage
What hail damage looks like
Hail strikes leave soft bruises in shingles, knock off protective granules, and crack the fiberglass mat underneath. These signs often require an on-roof inspection to identify.
Bruising
Soft circular spots in shingles
Hail impact loosens the asphalt mat from the fiberglass base, creating soft bruises that are often invisible from ground level. These bruises compromise shingle integrity and allow water infiltration over time.
Granule loss
Bare patches where granules are knocked off
Hail strips away the protective mineral granules that shield asphalt from UV exposure. Bare patches accelerate roof deterioration and are a clear sign of impact damage.
Mat cracks
Fractured fiberglass underneath
Impact cracks the underlying fiberglass mat that gives shingles structural strength. This damage is hidden but critical—it compromises the shingle from underneath.
Metal damage
Dented gutters and downspouts
Visible dents in gutters, downspouts, and metal flashings are indirect evidence of hail size and direction. These are often easier to spot from the ground than roof damage.
Vent damage
Circular impact patterns on vents
Roof vents and soffit vents show circular impact marks from hail. Damaged vents can leak and compromise attic ventilation if not replaced.
Ground signs
What you can see without climbing
Dented gutters, damaged vents, and granules in downspouts are visible indicators. However, most hail damage requires an on-roof inspection to fully assess.
Hail sizes
Hail size and damage correlation
Larger hail causes more severe roof damage. Understanding the relationship between hail size and damage helps determine whether your roof qualifies for an insurance claim.
Penny size
Three-quarter to one inch hail
Hail this size causes cosmetic damage to gutters and possible granule loss on older shingles. Damage is typically minor and rarely exceeds insurance deductibles.
Nickel size
One to one-and-a-half inch hail
This size causes functional shingle damage, especially on roofs over ten years old. Most insurance companies recognize this as the threshold for claim consideration.
Quarter size
One-and-a-half to two-and-a-half inch hail
Significant roof damage occurs at this size, with full-replacement claims becoming common. Damage extends beyond the roof to gutters, vents, and sometimes siding.
Golf ball
Two to two-and-a-half inch hail
Severe damage to roofing, gutters, and metal components. Insurance claims almost always cover full replacement at this impact level.
Tennis ball
Two-and-a-half inch hail and larger
Catastrophic damage to roofing, siding, windows, and skylights. Multiple systems often require replacement, and claims are extensive.
Baseball
Two-and-a-half inches and beyond
Extreme hail causes widespread structural damage. Roofs, siding, windows, and exterior components all sustain severe impact damage requiring full replacement.
Impact resistance
Class 4 impact-resistant shingles protect against hail
Class 4 shingles are rated for 2-inch hail at 90 mph under UL 2218 testing. Most Minnesota insurers offer 10-30% homeowners premium discounts when Class 4 is installed, often paying for the upgrade within 5-7 years.
SBS modified
Rubberized asphalt for hail resistance
SBS-modified rubberized asphalt is more flexible and hail-resistant than standard asphalt. Malarkey Vista, Highlander, and Legacy use this technology for superior impact performance without requiring a Class 4 rating.
Malarkey Vista
SBS-modified asphalt shingle
Vista combines SBS-modified asphalt with a durable fiberglass base. This mid-tier option offers excellent hail resistance and a 30-year warranty at a lower cost than Class 4 upgrades.
Malarkey Highlander
Premium SBS-modified option

Malarkey Legacy
SBS-modified with extended warranty
Legacy features SBS-modified asphalt and a 50-year limited warranty. This option balances hail resistance with long-term durability and value.
Atlas StormMaster
Class 4 impact-resistant shingle
