What’s different about Denver
Denver's fast growth and high cost of living strain contractor capacity, and Front Range hail makes impact-rated roofing a routine cost driver.
- Severe-storm exposure favors impact-resistant materials.
- Footings have to reach below the frost line, so deeper excavation adds cost.
How the cost is built
Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.
