Start with the symptom
Featured tool
This is a shortened version of the repair cost calculator. It uses the amount of repair — square feet, linear feet or the number of leak locations — never the size of the whole house.
A planning estimate, not a contractor quote. Model v1.0, rates provisional.
Open the full calculatorsquare feet of affected area. 10–500.
Planning range
$525 – $1,200
60 sq ft · Straightforward access
Labour, materials and basic cleanup for the scope described. Interior repair, structural work and full replacement are excluded.
This range is a planning estimate, not an offer from a company, and it does not replace a written quote after someone has seen the roof.

A quote is only comparable when you know what is inside it. Here is the line-by-line method we use to put two roofs, two scopes and two totals on the same footing.

Chimneys, valleys, walls, vents and skylights all rely on flashing. Understanding the details explains why two leaks that look identical can cost very differently.

Workmanship warranties, manufacturer material warranties and the exclusions that decide whether a callback is free. Read this before you sign anything.
Read the guideMethod and money
Cost ranges come from a published model with a version number, printed rates and stated assumptions. The rates are provisional planning inputs, not a survey of local market prices, and the output is a band rather than a quote. We do not apply a ZIP code multiplier to make a result look local.
Read the methodologyThere is no display advertising on this site. Future revenue comes from referral fees paid by companies that hold a written agreement with us. You are never charged to use a tool or read a guide, and no company can pay to change a guide, a calculation or its position in a comparison.

Something not covered? The contact page reaches the people who maintain the site and its guides.
Not everywhere, and not by default. This site currently runs in a tools-first phase: the calculators, cost guidance and guides are open to everyone, while company matching opens only for a ZIP code and job type where a company has confirmed coverage and a written referral agreement. Where that is not the case, we say so instead of taking your details.
No. RoofRepairRoof is a referral service. The inspection, the price, the schedule and any warranty come from the company you choose, not from us.
Where matching is open, your request is checked against the service areas participating companies have confirmed, then passed only to the companies you selected. Response times are set by each company, so we do not promise a callback window.
Only the companies you select yourself. We do not send requests to every contractor in an area, and we do not resell your details.
No. The calculator produces a planning band from a published model, with its assumptions printed next to the number. A quote is a written price for a defined scope after someone has seen the roof. The two are meant to sit side by side, not replace each other.
Nothing. No account, email address or phone number is needed for the calculators, the guides or the search page, and none of them upload your inputs anywhere.
There is no display advertising. Future revenue comes from referral fees paid by companies that have a written agreement with us, when a request is accepted, an appointment takes place or a completed job is confirmed. Nothing is charged to you, and no company can pay to change a guide or a calculation.
Estimate the repair, then read the guide for your roof type. No account and no email required.
