What an Adjuster Looks for During a Utah Hail Inspection
Learn how insurance adjusters evaluate roof hail damage across Utah, from collateral ground evidence and test squares to soft metal impacts.
When a severe storm moves through the Wasatch Front or Utah Valley, hail can cause significant roof damage that is invisible from the driveway. When you file a claim, your insurance company assigns an adjuster to inspect the property and determine whether the roof requires minor repairs or full replacement.
Homeowners often assume the adjuster simply glances at the shingles to make a decision. In practice, adjusters follow a structured, methodical inspection process. Understanding what an adjuster looks for helps you prepare for the inspection and understand the outcome of your claim.
Ground-Level Collateral Damage
Before an adjuster ever climbs onto your roof, they walk the perimeter of your home searching for collateral damage. Collateral damage consists of physical evidence on ground-level surfaces that confirms hail fell on your specific property, indicates the direction of the wind, and provides clues about the size of the hailstones.
Adjusters inspect soft metals and exposed components around the house. They look for clean dings and indentations in aluminum downspouts, window wraps, air conditioning condenser fins, painted garage doors, and exterior light fixtures. They also inspect vinyl or wood siding, painted decks, and patio furniture for fresh impact marks or splatters where oxidation has been chipped away.
If ground-level soft metals show zero signs of impact, an adjuster is less likely to attribute marks on your shingles to recent hail activity. Clear collateral damage, on the other hand, establishes a strong baseline for the roof inspection that follows.
The 10x10 Test Square Protocol
Once on the roof, adjusters generally do not examine every individual shingle. Instead, they use a standardized sampling method known as a test square. The adjuster measures out a ten-foot by ten-foot section (100 square feet, which equals one roofing square) using chalk on several distinct roof slopes or exposures.
Within that marked square, the adjuster inspects the shingles and circles every legitimate hail impact. An adjuster is not looking for surface discoloration or minor cosmetic scuffs. They are checking for structural compromise. They look for:
- Indentations that feel soft or spongy under fingertip pressure, which indicates the internal fiberglass mat has fractured.
- Granule loss that leaves the black underlying asphalt or fiberglass substrate exposed to ultraviolet light.
- Sharp tears or puncture marks penetrating through the shingle.
Insurance carriers establish internal thresholds for how many confirmed impacts must fall within a single test square to warrant replacing that roof slope. This number typically ranges between six and ten hits per square, depending on the carrier and policy specifications.
Soft Metals and Penetrations on the Roof
Roof accessories act as direct indicators of impact force. Because aluminum and thin-gauge steel dent far more easily than asphalt shingles absorb impact, adjusters examine every penetration on the roof.
Key areas of interest include metal exhaust caps (turtle vents), continuous ridge vents, furnace flue pipes, plumbing vent boots, and chimney caps. In older Utah neighborhoods and across rural areas, metal evaporative cooler (swamp cooler) covers are also inspected. The adjuster checks whether the dents on these metals share the same directional angle and severity as the marks on the shingles. If the soft metals are clean and unmarked, an adjuster will scrutinize shingle blemishes far more skeptically.
Distinguishing Hail Damage from Wear and Blistering
One of the most common reasons hail claims face partial or full denial along the Wasatch Front is the misidentification of pre-existing wear as storm damage. Adjusters are trained to differentiate genuine hail strikes from natural aging, foot traffic, and manufacturing flaws.
Blistering is a common point of confusion. Blisters occur when volatile gases trapped within an asphalt shingle expand during high summer heat—a frequent issue under Utah's intense sun, particularly on roofs with inadequate attic ventilation. When these blisters pop, they leave small circular spots with missing granules that resemble hail impacts. However, a popped blister leaves a hollow pit with raised, brittle edges and intact fiberglass underneath. A true hail strike leaves a crushed or bruised depression with micro-fractures in the mat.
Adjusters also look past mechanical damage, such as scrape marks left by painters' ladders or holiday light clips, and surface weathering caused by wind-driven sand and debris.
Scope of Loss and Slope-by-Slope Evaluation
After completing test squares across different directional exposures (north, south, east, and west slopes), the adjuster compiles a scope of loss. Hailstorms rarely strike a house evenly. Wind-driven storms frequently damage windward slopes while leaving leeward slopes untouched.
Depending on the age of the roof, the severity of the damage, and Utah building code requirements, the adjuster will calculate whether to pay for spot repairs, the replacement of damaged slopes only, or a full roof replacement. They will also review local building codes, such as requirements for ice barrier membranes along the eaves or drip edge installation, to determine which code-upgrade line items should be covered.
If you suspect storm activity has damaged your roof, having an experienced professional inspect it before the adjuster arrives can ensure all legitimate damage is documented.

Common questions
Should my roofing contractor be present during the adjuster's inspection?
Yes. Having your roofing contractor present ensures that all points of damage—including collateral evidence and damage to hard-to-see valleys or flashing—are pointed out and reviewed collaboratively before the adjuster finishes their report.
How does an adjuster tell the difference between hail damage and an old blister?
A hail impact creates a physical bruise or fracture in the underlying fiberglass mat, often leaving loose granules around a shallow depression. A blister is caused by trapped moisture or gas expanding from heat; when it pops, it leaves a hollow center with crisp, raised edges and no mat fracture.
What happens if the adjuster approves only one slope of my roof?
If damage is isolated to one exposure, the adjuster may write an estimate to replace only that slope. However, your contractor can inspect the remaining slopes for overlooked damage or evaluate whether local building codes and shingle availability allow for a partial replacement without compromising roof integrity.
