Does a New Roof Pay Off at Resale? Roof Replacement ROI
A new asphalt roof recoups about 60% of its cost at resale — but the bigger value is that it often lets the home sell at all.
Construction calculators
Estimate materials and cost before you call a contractor
Walk into any quote knowing the numbers. Our construction calculators turn a few measurements into the squares, boards, bags, and dollars a real job takes — using the same take-off rules the trades use.
Material take-offs
Convert dimensions into squares, boards, sheets, and bags with realistic waste built in.
Cost ballparks
See installed price ranges by material so you can sanity-check a contractor's bid.
Insurance & claims
Understand roof depreciation, RCV vs ACV, and what a storm claim is likely to net.

Plan a home project like a pro
Most home-improvement surprises come from one place: not knowing the quantities. How many roofing squares is your roof, really? How many gallons of paint, sheets of drywall, or cubic yards of concrete will the job swallow? Guess low and you stall mid-project; guess high and you waste money. A quick estimate up front removes both risks.
Each calculator here is built around the standard take-off math contractors use — pitch multipliers for roofs, waste allowances for siding and flooring, on-center spacing for joists and fence posts. They won't replace a measured quote, but they'll tell you whether a bid is in the right ballpark and help you buy the right amount of material the first time.
Start with the calculator that matches your project, then read the guides below to understand what drives the price and where estimates go wrong.

Frequently asked questions
- How accurate are these construction estimates?
They use standard industry formulas and typical waste factors, so they're good for budgeting and material orders. Final numbers depend on your exact layout — always confirm with a contractor's measured take-off before a big purchase.
- Do the cost calculators include labor?
The cost estimators show installed ranges that include typical labor and materials. Repairs, permits, demolition, and regional rates can shift the real figure, which is why we show a range.
- Which calculator should I start with?
Pick the one that matches your project — roof, deck, siding, gutters, concrete, paint, drywall, flooring, mulch, or fence. Measurement tools come first; cost ranges follow.
