Can Small Hail Really Damage a Roof?

Small hail, often under an inch in diameter, might not break through a roof on impact, but it can still cause harm. The force of hail hitting a roof repeatedly, especially during a storm with high winds, can bruise asphalt shingles, cracking their surface and dislodging the protective granules. These granules shield the shingle from the sun's UV rays, and once they are gone, the shingle ages faster and becomes brittle.

On metal roofs, small hail can create small dents, which may not leak immediately but can stretch the metal and weaken seams over time. On tile or slate roofs, hail can chip edges, exposing the underlying material to moisture. The damage is often not visible from the ground, so a roof that looks fine after a storm may still have hidden weak points that lead to leaks later.

• Cracks in asphalt shingles allow water to seep under the surface
• Loss of granules accelerates shingle aging and makes them brittle
• Dents in metal roofs can stress seams and fasteners
• Chips in tile or slate expose the roof deck to moisture
• Damage may be invisible from the ground, hiding potential leaks

If you suspect hail damage, or if the storm was severe, consider scheduling a roof inspection. A water damage inspection can identify hidden issues that you cannot see from the ground, such as weakened shingles or compromised flashing. The pros can also check for water damage in your attic or ceiling that might have already started.

If the inspection reveals damage, the next step is repair. For minor issues, such as a few cracked shingles, a simple replacement might be enough. For more widespread damage, the pros may recommend a full roof replacement or an overlay, depending on the age and condition of your roof. The cost can vary widely, often ranging from a few hundred to several thousand dollars, depending on the extent of the damage and the roofing material.

In some cases, hail damage can lead to water intrusion, which requires water damage cleanup and repair. If the roof leak has already caused damage to your ceilings, walls, or insulation, you will need to address that as well. The pros can handle both the roof repair and the interior water damage, ensuring your home is dried out and restored to a safe condition.
