How Do Inspectors Test for Hail Damage on a Roof?
Last updated October 26, 2026
The short answer
What Inspectors Look For
When inspecting for hail damage, the pros start with a visual walk around your property. They look at the roof surface, gutters, downspouts, and any metal components like vents or chimney caps. Hail impact often leaves small, dark bruises on asphalt shingles, which are soft spots where granules have been knocked loose.
On metal roofs, hail can create dents or creases. On wood shakes, it may split the material. The pros also check for cracked or displaced shingles and loose granules in the gutters, which can signal recent impact. A flashlight helps them spot subtle damage in shaded areas.
They also inspect the flashing around chimneys, skylights, and roof valleys, as these are common weak points. If hail was large enough, it can dent or loosen flashing, creating entry points for water. The goal is to find all damage, not just the obvious dents.

Using Tools for a Closer Look
Visual checks are the first step, but the pros often use simple tools to confirm damage. A moisture meter can detect damp areas in the roof deck or insulation, which may indicate a leak from hail impact. This is especially useful after a storm, as leaks can take time to show up inside your home.
They may also use a probe or screwdriver to test the firmness of shingles. A soft or spongy spot can indicate bruising that isn't visible from the ground. For taller roofs, binoculars or a drone might be used to get a closer view without walking on the surface, though a hands-on check is still the most thorough.
Some inspectors use a rubber mallet to tap on shingles, listening for a hollow sound that suggests a loss of granules or a cracked base. This is a quick, non-destructive way to assess the integrity of the roofing material. The pros combine these methods to paint a full picture.
What Happens After the Inspection
Once the inspection is complete, the pros will document their findings. This includes taking photos of any damage they find and noting the extent of the impact. This documentation is useful if you need to file an insurance claim, as it provides evidence of the damage.
Policies vary, and your insurer decides what is covered. The inspector's report can help you show what happened, but it's up to your insurance company to determine if the damage is covered. You should review your policy and talk to your insurer about your specific situation.
If the inspection reveals damage, the next step is usually roof repair or replacement. The pros can also check for water damage inside your home, such as soaked insulation or stained ceilings. Addressing leaks quickly can prevent more serious issues like mold or structural rot.
Why Professional Inspection Matters
A professional inspection is more thorough than a quick glance from the ground. The pros know where to look and what signs to check for. They can also safely walk on the roof, which is risky for the average homeowner.
Hail damage can be subtle, and missing it can lead to leaks and water damage down the road. A professional assessment can catch issues early, saving you from costly repairs later. If you suspect hail damage, it's worth getting a professional opinion.
A professional inspection also provides a written record, which can be helpful if you need to make an insurance claim. The pros can detail the extent of the damage and the likely cause. This documentation is a key part of the process.
When to Get an Inspection
You should consider a roof inspection after any hailstorm with hail larger than a quarter inch in diameter. Also, if you notice signs of damage, like missing shingles or water stains on your ceiling, it's time to have a professional look. Acting quickly can prevent further damage.
The pros can also inspect your roof as part of a routine maintenance check, especially if your roof is older or has been through a harsh winter. In cold, snowy winters with warm, humid summers, roofs take a beating, so regular checks are wise.

Can I inspect my roof for hail damage myself?
You can do a visual check from the ground, looking for dents on gutters or missing shingles. But a safe, thorough inspection usually requires getting on the roof, which is risky. The pros have the training and equipment to do it properly, so it's often worth hiring them.
Does hail damage always cause leaks right away?
No, hail damage may not leak immediately. The impact can weaken shingles or create small cracks that take time to let water through. That's why it's important to have an inspection soon after a storm, so you can catch damage before it turns into a bigger problem.
What should I do if I find hail damage?
First, document the damage with photos and notes. Then, contact a professional to assess the extent and recommend repairs. Your insurance company may also need to be involved, so check your policy to understand what's covered. Policies vary, and your insurer decides what is covered.
