Asphalt Shingle Roof Replacement Cost Calculator FAQs
How much does it cost to reroof a 2,000 sq ft house?
A 1,500–2,000 sq ft roof — the most common size — costs $7,400–$10,900 installed with architectural shingles, including standard tear-off of a single existing layer.
3-tab vs. architectural shingles — what's the price difference?
Architectural (dimensional) shingles cost about 24% more than economy 3-tab shingles, but last longer (25–30 years vs. 15–20) and carry a stronger wind rating, which is why most homeowners choose them.
Does tear-off cost extra, or is it included?
Tear-off of the old roof is a separate line item: $0.80–$1.20/sq ft for one existing layer, $1.30–$1.90/sq ft if there are two layers to remove.
What if my roof deck is rotted underneath?
Rotted decking (plywood/OSB sheathing) is priced separately once it's exposed during tear-off — $2.00–$3.50/sq ft for a partial replacement, $3.50–$5.50/sq ft if the whole deck needs replacing.
