Most Connecticut homes
The default high-value system: strong wind rating, widest color range, full system warranty.
Ratings reflect typical manufacturer published values for properly installed systems. Final warranty and wind ratings depend on the specified assembly and deck condition.
Reading the table
What actually drives cost
Material is rarely the biggest variable. Roof complexity — valleys, dormers, hips, chimneys and skylights — drives labour hours, and steep pitch or multiple stories adds staging and safety cost. Surface area typically runs 15–40% above the building's footprint once pitch is accounted for.
Deck condition is the wild card. We quote a per-sheet rate for replacement up front so there is no surprise number once the old roof is off.
Shoreline exposure
Coastal wind uplift requirements and salt exposure add around 10%.
Detail count
Chimneys, skylights and valleys are priced individually, not averaged in.
