About Us

 Home Repair Cost Lab helps U.S. homeowners understand what repairs, replacements, and home upgrades are likely to cost before they hire a contractor.

Home projects can be expensive, confusing, and difficult to compare. A roof estimate, HVAC replacement quote, plumbing repair, or electrical upgrade may vary widely depending on your location, home size, materials, labor, permits, and the condition of the existing system.

Our goal is simple: to make those decisions easier.

Here you’ll find practical cost guides for common home projects, including roofing, heating and cooling, plumbing, electrical work, windows, siding, foundations, water damage, pest control, and energy upgrades. We explain typical price ranges, the factors that change the final cost, when repair may make sense, and when replacement may be the smarter long-term choice.

Home Repair Cost Lab is an educational resource. Every home and contractor quote is different, so use our guides as a starting point for planning, comparing estimates, and asking better questions before you commit.

We believe homeowners make better decisions when the numbers are clear.

How Much Does a Roof Replacement Cost in 2026? A Real-World Pricing Guide

By Home Repair Cost Lab Editorial Team · Updated September 5, 2026 Quick answer: Most homeowners replacing a standard asphalt-shingle roof in 2026 should budget $8,500–$18,000 , though the real number depends far more on your roof's measured area, pitch, and layers than on your home's square footage. Below, we break that range down by material, region, and what should — and shouldn't — be in your written quote. Editor's note: This guide was compiled by cross-referencing contractor-facing cost data with published guidance from the National Roofing Contractors Association (NRCA), the U.S. Department of Energy, and the U.S. Environmental Protection Agency. It is updated periodically as material and labor costs shift. It is not a substitute for a written, itemized quote from a licensed local contractor. Why "cost per square foot of house" is the wrong question A 2,000-square-foot house does not have a 2,000-square-foot roof. A two-story colonial c...

Asphalt Roof Replacement Cost per Square: A 2026 Bid Guide

Image
For an asphalt-shingle replacement, a national planning screen is about $400 to $1,200 per roofing square , or $8,000 to $24,000 for 20 measured squares. Confirm tear-off and disposal, because roof shape, access, flashing, old layers, and deck repairs can push a complete proposal beyond that range. The range is broad because a roofing square describes area, not difficulty. Twenty squares on a simple one-story ranch are not the same job as 20 squares divided among steep slopes, dormers, valleys, skylights, and a chimney. One roofing square covers 100 square feet Roofers price and order material in squares. One square equals 100 square feet of actual roof surface, so a measured 2,000-square-foot roof contains 20 squares. Actual roof surface is the number that belongs in the estimate. Interior floor area is a poor substitute because it does not capture slope, overhangs, attached garages, porches, hips, valleys, or dormers. A compact two-story house can have less roof area ...
