Simply input your roof slope and basic measurements, choose the desired roofing material and get your results.

Your roofing cost estimate includes all materials, accessories and labor by a licensed and insured roofing contractor. You can also specify your location to get a “local” cost.

How To Use Roof Replacement Calculator

1) Measure your roof – with a tape measure, go corner to corner and measure ground dimensions of your home. If it has overhangs, add them to your sizes.

For example: If overhangs are 6″, add 1 foot to each side. If overhangs are 2 feet on front an back, and there are no overhangs on the sides, add 4 feet to the appropriate side.

Roof replacement cost 2) Enter the slope – you can guesstimate or measure it. Home Depot sells a visual “pitch measuring tool”, or you can use a simple square tool, line it up with your roof’s gable and measure RISE over RUN – see image on the right.

3) Select roof type – if you have a simple gable (ranch / cape / colonial type homes), select that. If you have hips, dormers, select “hip”. If it is all cut up, and has different slopes and angles, select the appropriate option.

4)Tear-off – it is always a good practice to remove old shingles. This will allow the contractor to repair any damaged wood below, and will prolong the life of the new material. Select the number of layers that need to be removed.

5) Select number of floors – it is much easier to work on a 1 story house vs. a triple decker. This will always be reflected in the total you are about to pay.

6) Chimneys, skylights and ridge ventilation – enter the number of penetrations and the length of your ridge line (if you are getting a ridge / soffit vent system). Most homes have at least one chimney, so you should add that.

7) Enter roofing material – the quality and longevity will be reflected in the total roof replacement cost. 30 year asphalt shingles are the cheapest, while a metal roof is much more durable and therefore more expensive. Among single-ply options, PVC membrane is the best and most costly choice, while EPDM rubber is the cheapest and least durable flat roofing option.

8) Select your location – roofing cost can vary greatly depending on where you live. By selecting your region, the tool will adjust the price accordingly (data is based on Remodeling Magazine’s local prices guide). If you are unsure, or live in Canada, select National Average.

Keep in mind that there are many factors that will affect how much you will end up spending on replacing an old roof.

Get The Best Price On A New Roof

The key to getting a new high quality roof at a reasonable price is to know how much roofers charge for their work, and negotiate with a roofing company before hiring them.

Roof Replacement Cost Estimator will give you a very good idea of what a real roofing estimate should be. This information will help you understand whether a pro is offering a fair deal, or trying to overcharge you.

We aggerate real roof pricing data from real contractors across the US. By entering your zip code, you are getting roofing prices that are currently true for your area of residence, based on roofer’s labor fees in your city or town, or surrounding areas.

How Much Do Roofers Charge Per Square?

Most roofing contractors in US and Canada have a similar formula as the one we use here. Typically, it is based on SQUARES (100 sq. ft. of area).

Unless you have a super cut-up house, 95% of contractors will price it by the square. This makes it very easy to compare quotes, and choose the best deal.

On average, you can expect to pay $360 – 590 per square, which is equivalent to $3.60 – $5.90 per square foot.

Keep in mind that this pricing can go up or down depending on the material you are choosing to install.

Asphalt shingles are the cheapest and easiest to install, so roofers charge the lowers labor fees for this roofing material.

On the other hand, metal roofs, clay and concrete tile roofs, or slate roofing, which are all high-end specialty roofing materials, incur much higher labor rates that can go up to as much as $1,100-1,800 per square.

What To Look For When Hiring A Roofer

When you start looking for a pro to replace your roof, your goal is to find someone honest, reliable and reasonably priced.

The first thing you should look for in a potential roofer is whether he is licensed and insured. This the number 1 sign that you are dealing with a reputable business. Be very cautious of companies that have NO insurance and workman compensation, as these are most likely hiring illegal workers to keep their costs low.

While you might save money in the short term, you run the risk of getting poor installation quality and serious roofing problems down the line. Also, these “cheap” roofers often disappear on you after completing the project and will not take responsibility for their work, in case something goes wrong.

The second thing you should look for is at least 3 references of recently completed jobs in your area. Ideally, you should do your homework and actually call at least 1 of these references to get a sense of how the homeowner liked this roofer’s work process and the final result.

Thirdly, you should check out if the roofer is doing a thorough inspection of your roof and is willing to spend time to answer all your questions.

You want to hire someone who will treat your roof as if it was his own. Many roofers like to fly through install, saving time and cutting corners in order to move on to the next job. You want to make sure that the pro your hire will give your roof top priority and the attention your home deserves.

Lastly, you should do thorough research on the roof installation prices in your area, prior to getting actual roofing quotes.

Many roofers are notorious for jacking up costs, if they see that the homeowner has no clue how much a roof replacement should cost. When you have some figures in mind, it will be much easier for you to negotiate a good deal with a roofer.

Its best to select a small to mid-size contractor who can produce good references from past clients, is bonded and insured. In many of these companies, the owner participates in and closely oversees the installation, and is very invested in making clients happy.

      Hi David,

      Thanks for asking. Yes it does include cost of labor. If you were to calculate materials only, they are usually 1/3 of the total job cost… sometimes a little more, depending on what shingles or other material you are using.
