How much does a roof replacement cost?
The material used is a significant, yet controllable factor in the cost of your roof. From asphalt shingles to metal roofing, your material cost can vary greatly.
The pitch of the roof (how steep it is) can affect how difficult it is to remove the old roof and install the new one as well as whether additional structures such as scaffolding might be needed for the installation.
Depending upon where you live, building codes have varying requirements for roofing materials and their installation which could add to material and labor costs.
Skylights, chimney or other adornments
The presence of skylights, a chimney, plumbing pipes or other items extending through the roof can make a roofing job more complicated and more costly.
It stands to reason that a larger roof will cost more to replace than a smaller roof.
Depending upon where you live, labor costs can vary widely. Things that affect labor costs besides location are factors that will increase the amount of time required to tear down your old roof and install a new one. For instance, if you have an asphalt shingle roof with multiple layers of shingles, it will take longer to remove than one with a single layer of shingles and will consequently cost more.
Estimating Roof Replacement Costs
Caution – Math Ahead!
What you’ll need:
- A level (at least 48 inches long)
- A carpentry square A calculator
- The size of your home in square feet
What to do: First, determine the pitch of your roof. this can be accomplished by measuring how many inches your roof rises over one foot of length either at the edge of the roof (using a ladder) or inside your attic. Here’s an image to demonstrate that measurement.
Once you’ve determined your roof pitch or slope, use the following table to obtain the multiplying factor. Now multiply the factor by the number of square feet covered by your roof. This will give you an estimate for the square footage of your roof. Divide this number by 100 and then multiply by the high and low roof costs in the table above based upon the type of roof you want in order to get a ball park range.
Things to remember:
This estimating tactic is very basic and doesn’t take into consideration gables or other more complex roofing challenges.
Don’t forget to include the square footage for an attached garage in your calculation!
Always get multiple quotes from licensed contractors
Cost estimates can vary widely, even in the same local market, dependent upon the season, how busy the contractor is and more. Getting multiple quotes allows you to more closely determine a fair price for your roof replacement.
Don’t automatically choose the lowest quote
Sometimes the lowest quote can mean a bargain, but sometimes it can mean that the contractor is cutting corners and performing shoddy workmanship. If a quote is a lot lower than the others, there is probably a reason to steer clear.
Ask for references
Always ask your prospective roofer for references. This will give you a chance to talk to former customers and find out if there were any unpleasant surprises during the job.
