Chalk Codes For Wind Damage To Roof
Severe windstorms cause an estimated $18 billion in property damage annually in the U.S., with roof damage being the most common issue reported by homeowners, according to FEMA and NOAA. One often-overlooked but essential part of identifying this damage involves “chalk codes”—a systematic method of marking and documenting roof damage for inspections, insurance claims, and repairs.
If you’re a homeowner in Asheville, NC or anywhere in a wind-prone area, understanding Chalk Codes For Wind Damage can save you thousands in roofing repairs or denied insurance claims.
What Are Chalk Codes?
Chalk codes are visual markings made by roofing professionals or insurance adjusters using chalk to indicate:
- Shingle creases (evidence of lift from wind)
- Missing shingles or tabs
- Nail pops or displaced fasteners
- Debris-caused punctures
- Wind direction indicators
Each type of damage is assigned a specific code or symbol (e.g., circles for creases, arrows for lifted edges), helping professionals document and justify necessary repairs.
Common Types of Wind Damage Detected with Chalk Codes
| Damage Type | Chalk Code Used | Description | Insurance Implication |
|---|---|---|---|
| Lifted Shingles | Arrows | Shows wind pressure lifted shingle edges | Often covered if >3 shingles |
| Missing Shingles | “X” or Box Outline | Indicates total loss from wind shear | Always covered under wind clause |
| Creased Shingles | Circles | Sign of wind bending shingle against the roof | Covered if creasing = failure risk |
| Nail Pops | Dot + Label “NP” | Nails pushed up by uplift pressure | Sometimes covered if leak occurs |
| Torn Tabs | Slashes or Zigzags | Visible tears caused by high winds | Usually covered if multiple exist |
