How to Identify Hail Damage on a Commercial Metal or Flat Roof

Hailstorms can cause significant damage to various types of roofing, including metal and flat roofs. Identifying hail damage early is crucial to prevent further damage and costly repairs. Here's a comprehensive guide to help you spot hail damage on your metal or flat roof.

Understanding Hail Damage

Hail damage can vary significantly based on the size of the hailstones, the wind speed during the storm, and the type of roofing material. While metal roofs are generally more durable than other materials, they are not immune to damage. Flat roofs, often covered with membrane or asphalt, can also suffer substantial harm.

Signs of Hail Damage on a Metal Roof

  1. Dents and Dings:
  • Visual Inspection: Look for small dents or dings on the metal panels. Depending on the hailstone size, these are often visible and can range from shallow to deep.
  • Feel the Surface: Run your hand over the roof’s surface to detect any indentations that might not be immediately visible.
  1. Paint Damage:
  • Chipping or Cracking: Check for chipped or cracked paint, which can expose the metal underneath to rust.
  • Scratches: Look for scratches, particularly in areas where hail might have hit at an angle.
  1. Fastener and Seam Issues:
  • Loose or Missing Fasteners: Hail impact can loosen or dislodge screws and fasteners, compromising the roof’s integrity.
  • Seam Separation: Inspect seams for any separation that might have been caused by hailstones.

Signs of Hail Damage on a Flat Roof

  1. Punctures and Tears:
  • Membrane Inspection: Look for punctures or tears in the roofing membrane. These can lead to leaks if not repaired promptly.
  • Felt Displacement: In built-up roofs, check for displacement of felt layers, which can expose underlying materials.
  • Circular Patterns: On TPO roofing, look for circular patterns. This is where the hailstone made an impact and there could be damage under the membrane if it is not already visible.
  1. Granule Loss:
  • Surface Texture: Examine the surface for areas where granules have been knocked off, revealing the underlying substrate.
  • Bald Spots: Look for bald spots on the roofing material where the protective granule layer is missing.
  1. Pooling and Drainage Issues:
  • Water Accumulation: After a hailstorm, check for areas where water is pooling. This might indicate depressions caused by hail impacts.
  • Drainage System: Ensure that debris knocked loose by the storm does not block drains and gutters.

  1. File an Insurance Claim:
