Roof Installation Guide

Everything you need to know about the roof installation process. Understand what to expect, how long it takes, and how to prepare for your Denver roof replacement.

Typical Timeline

Most asphalt shingle roofs take 1-3 days. Complex roofs or premium materials may take longer.

Best Season

Late spring and early fall offer ideal conditions in Denver. Avoid peak hail season (May-August) if possible.

Weather Dependent

Installation requires dry conditions. Denver's afternoon storms may cause delays during summer months.

Denver-Specific Considerations

  • Schedule installation during dry weather (April-October ideal)
  • Avoid installation during Denver's hail season if possible (May-August)
  • Allow for weather delays - afternoon thunderstorms common in summer
  • Ice and water shield is critical for Denver's freeze-thaw cycles
  • Proper ventilation is essential for Denver's temperature extremes
  • Choose impact-rated materials for hail protection
