A storm counts when the library lists Jefferson County among the areas it hit. Each hail size is the storm's largest report, which may have fallen in a neighboring county, and insured losses cover every area the storm hit.
Roofers in Morrison first have to know whose permit they need: the Town of Morrison runs its own building department (permits and inspections through its contracted firm, Charles Abbott Associates), while homes outside town limits are generally under Jefferson County, which requires a mid-roof and a final inspection in person and does not accept photos. In mapped wildfire areas, the Colorado Wildfire Resiliency Code also requires a Class A roof covering. In the foothills, wind, snow and wildfire all shape the right roof choice.

Choosing a roof for a Morrison home
- Wildfire. In mapped areas the roof must be Class A. Asphalt shingles, metal, tile and slate can all meet it; for synthetic cedar, check the product’s listing. Real wood shakes do not qualify on their own. Our Colorado Wildfire Resiliency Code guide explains when a reroof triggers the full rules, and our guides to ember-resistant vents and gutters and debris cover the rest of the roof edge.
- Snow. Metal sheds snow quickly; plan snow guards over doors and decks.
- Wind. Shingles need the right wind classification and the manufacturer’s high-wind nailing.
- The 25% rule. In a mapped area, a large hail repair can trigger a full replacement. The claim stays yours; our photos make sure nothing gets missed in the scope.
