Frequently Asked Questions
How much does new roof installation cost on new construction?
New roof installation for new construction costs $5–$18 per sq ft depending on material, since there is no tear-off cost. Architectural shingles cost $5–$8 per sq ft installed. Metal roofing costs $10–$18 per sq ft. This includes decking, underlayment, shingles/panels, flashing, ridge cap, and labor. A 2,000 sq ft home with architectural shingles costs $10,000–$16,000.
What components are included in a new roof installation?
A complete new roof installation includes: roof decking (OSB or plywood), ice and water shield at eaves and valleys, synthetic underlayment over remaining area, drip edge flashing, step flashing at walls, chimney and skylight flashing, roofing material (shingles, metal panels, or tile), ridge cap, and pipe boot flashings. Gutters are typically a separate cost.
How long does a new roof installation take?
New roof installation on a standard home takes 2–5 days depending on size and complexity. Simple gable roofs go faster. Complex roofs with multiple valleys, dormers, skylights, and chimneys take longer. New construction installations often take a bit longer than re-roofing since decking must be installed first, but there is no tear-off delay.
What roofing material should I choose for new construction?
Architectural asphalt shingles are the most common choice offering good value, 25–30 year lifespan, and compatibility with most architectural styles. Metal roofing costs more upfront but lasts 50+ years and adds resale value. Tile is ideal for Mediterranean or Spanish-style homes in warm, dry climates. Choose based on your climate, aesthetic preferences, HOA requirements, and long-term budget.
