How It Works
Our roof replacement calculator estimates costs based on your home's footprint, which we convert to approximate roof area (accounting for typical roof pitch). We then calculate costs in roofing "squares"—the industry standard unit of 100 square feet.
Material costs vary significantly. Basic 3-tab asphalt shingles are most affordable but last 15-20 years. Architectural shingles offer better aesthetics and 25-30 year lifespans. Metal roofing lasts 40-70 years with minimal maintenance. Tile and slate can last 100+ years but require structural support.
Multi-story homes cost more due to increased labor difficulty and safety requirements. Complex roof shapes with many valleys, dormers, or skylights also increase costs beyond these estimates.
Frequently Asked Questions
How long does roof replacement take?
Most residential roof replacements take 1-3 days for asphalt shingles. Metal roofs typically take 3-5 days. Tile or slate installations can take 1-2 weeks due to the weight and complexity of materials.
How do I know if I need a new roof?
Signs include missing or curling shingles, granules in gutters, daylight through roof boards, sagging areas, or a roof older than 20-25 years. If your neighbors are replacing similar-aged roofs, it's often a good indicator. Get a professional inspection to be sure.
Should I repair or replace my roof?
Repair if damage is isolated and your roof is under 15 years old. Replace if damage is widespread, repairs exceed 30% of replacement cost, or your roof is nearing end of life. Multiple repair patches can cause problems and void warranties.
Will homeowners insurance cover my roof?
Insurance typically covers roof damage from sudden events like storms, hail, or fallen trees. It doesn't cover normal wear and tear or neglected maintenance. Document damage with photos and file claims promptly. Roofs over 20 years may only receive depreciated value.
What's the best roofing material for my climate?
Asphalt shingles work well in most climates. Metal roofs excel in areas with heavy snow or fire risk. Clay tiles suit hot, dry climates. Slate works anywhere but is very heavy. Consider local weather patterns, HOA requirements, and your home's structural capacity.
