Quick estimate based on square footage, material, complexity, and tear-off layers. Updated in real-time as you adjust inputs. Final quote requires inspection.
Material costs are based on current Houston market pricing (mid-2026) for installed roofing systems. Architectural asphalt runs $4-$7 per sq ft installed; Class 4 adds $1-$2 per sq ft; metal $11-$18; tile $12-$32; slate $25-$50.
Tear-off cost scales with layers. Houston code requires full tear-off (no install-over). Single-layer tear-off is the most common; 2-3 layer homes are usually older Heights, Bellaire, or Memorial homes that have been re-roofed multiple times.
Complexity multiplier reflects labor variance. A simple gable roof with one pitch installs significantly faster than a custom estate with multiple slopes, dormers, and copper accents. The simple-to-estate range is roughly 0.85x to 1.25x the base labor cost.
What this calculator doesn’t capture: deck rot extent (only known after tear-off), specific HOA requirements (some require premium materials), code-required ventilation upgrades, structural reinforcement (for tile or slate retrofits), and specific accessories beyond standard scope. The estimate is a starting point, not a final quote.
