What to Look for When Checking Your Roof After a Hailstorm

Start your inspection from the ground

After a severe storm passes, your first instinct might be to climb onto the roof and look for damage. That can wait. The safest way to begin is from the ground, using a pair of binoculars. Walk around the house and scan the entire roofline. Look for obvious issues such as missing shingles, bent flashing, or sections where the roof surface seems uneven. Hailstones can leave visible dents or dimples on metal components like vents, gutters, and downspouts. If you see any of those signs, the roofing material itself has likely taken a hit as well.

Pay attention to the ground around your home, too. Granule loss from asphalt shingles often collects in gutters or on the lawn below. If you notice piles of small, dark granules near downspouts, that is a strong indicator that your shingles have been battered by hail. Similarly, fragments of tile or pieces of metal flashing on the ground point to impact damage. These clues help you decide whether a closer, more thorough inspection is necessary.

Check the attic for signs of water intrusion

Before you go up on a ladder, head inside to the attic. A flashlight and a dry day are all you need. Look for daylight coming through the roof decking. Even a small gap can mean the roof's protective layer has been compromised. Water intrusion often shows up first as dark stains on the wood or insulation. Damp spots, mold, or a musty smell are all red flags. If you find any of these, the roof has been breached somewhere above.

Also check the underside of the roof sheathing for any soft or rotted areas. Hail damage can create small punctures that are hard to spot from above but become obvious from below. This step is especially important after a storm with large hailstones or high winds, because wind uplift can lift shingles and create gaps that let water in. Catching these issues early can save you from more extensive repairs down the road.

Inspect the roof surface safely

If you decide to inspect the roof surface yourself, do it only when conditions are safe: the roof is dry, the weather is calm, and you have a stable ladder and proper footwear. Walk carefully along the ridge or valleys where footing is more secure. Start by looking at the overall layout. Are there any shingles that are clearly missing, cracked, or displaced? Hail damage often leaves circular fractures or spiderweb cracks on asphalt shingles. On wood shakes, look for splintering or splits. For metal roofs, check for dents, creases, or punctures that could lead to rust later.

Pay special attention to the roof flashing around chimneys, vents, and skylights. Flashing is a common weak point after a hailstorm. Hail can dent or tear these metal pieces, and wind can pull them loose. If the flashing is damaged, water can seep into the joints and cause leaks that are hard to trace. Also inspect the ridge caps and hip caps. These are often made of a softer material that can be crushed or dislodged by heavy hailstones.

Look for granule loss and blistering

Granule loss is one of the most telling signs of hail damage on asphalt shingles. The granules are the small, sand-like particles embedded in the shingle surface. When hailstones hit, they knock those granules loose. Over time, the exposed asphalt can dry out and crack, shortening the roof's lifespan. If you see patches where the shingle looks bald or the granules are piled in the gutters, that section likely needs repair or replacement.

Blistering is another thing to watch for. Hail impacts can cause the shingle layers to separate, forming bubbles or blisters beneath the surface. These blisters may not leak immediately, but they weaken the shingle and make it more prone to tearing during the next storm. Gently press on any suspicious bumps. If the shingle feels soft or spongy, the damage is already progressing.

Assess the condition of roof decking and underlayment

Sometimes the damage is not visible from the top surface. If you have access to the roof from the attic, check the decking for any sagging or soft spots. Hail that is large enough can actually break through the shingle and the underlying wood. That kind of damage requires immediate attention from professional help after hailstorms. A compromised deck means the roof's structural integrity is at risk, and a simple patch will not hold.

The underlayment, which sits between the shingles and the decking, can also be torn or punctured. If the underlayment is damaged, moisture can get trapped inside the roof assembly, leading to rot and mold. Even if the shingles look fine, a hidden tear in the underlayment can cause problems later. This is one reason why a thorough inspection by a trained eye is so valuable.

Document everything for your insurance claim

If you find damage, start documenting it right away. Take clear photos from multiple angles, and note the date and location of each issue. An insurance claim will be much smoother if you have visual evidence. Also keep any samples of damaged materials, such as a broken shingle or a piece of dented flashing. Your insurance adjuster may ask for them. The sooner you file the claim, the sooner you can schedule repairs.

Keep in mind that some damage is not obvious until weeks or months later. For example, a small crack in a shingle may not leak immediately, but after a few rain cycles it can widen and cause water intrusion. So it is smart to recheck your roof after the first heavy rain following a storm. If you notice new stains on the ceiling or walls, that is a sign the damage was more extensive than it first appeared.

When to call in a professional

Walking on a roof after a storm is risky, especially if the surface is slick or the structure may be weakened. For many homeowners, the safest route is to arrange a free roof inspection with a qualified contractor. A professional can spot subtle damage that the untrained eye might miss, such as hail dents on metal that will eventually rust, or granule loss that is still minor but progressing. They also have the tools to check for hidden issues like moisture trapped under the shingles.

Even if you feel confident about your own inspection, a second opinion from a roofer can give you peace of mind. They can also help you prioritize repairs and give you a clear estimate for the work needed. This is especially important if you plan to file an insurance claim, because the contractor's report can serve as a professional assessment of the damage.

Final thoughts

After a hailstorm, the condition of your roof should not be a guessing game. A careful, step-by-step inspection can reveal problems before they turn into expensive leaks. Start from the ground, move to the attic, and then check the roof surface if it is safe. Look for missing shingles, granule loss, damaged flashing, and any signs of water intrusion. Document everything and consider enlisting professional help after hailstorms to make sure nothing is overlooked. Taking these steps now will protect your home and your wallet in the long run.
