Roof Replacement Cost Estimator

Our roof replacement cost estimator can help you better understand the main factors that determine pricing. You really need to price out roof replacement cost for your own specific project, based on a number of factors to get the most accurate figure. Costs can run anything from $1000 to $85,000 or more, so there is a lot of variation to consider. Here are the primary factors that affect our roof replacement cost estimator.

Material
Asphalt shingles, wood shingles, metal, gravel, slate, terracotta and tile – there are numerous options and each comes in at very different price points. Asphalt shingles are one of the most inexpensive options and slate, tile and terracotta are some of the priciest.

Roof Design
The type of roof you have, whether a basic gable roof, low slope roof, flat roof, or dormered roof, will affect the cost because it will affect how difficult the job is to complete and may also determine what type of materials you need to use. Accessibility to the roof will also be dictated by design and will affect labor costs.


Pitch and Slope
Not only will the pitch of your roof determine how much extra precaution needs to be taken during the installation process (which can affect labor costs), but it may also affect the type of materials that can be used and the methods by which they can be installed.

Tear Offs Or Removal
If a new roof can be installed over your existing roof it will be less costly than if the existing roof needs to be removed prior to installation. There is a lot more labor involved in first removing an existing roof, as well as the cost to remove the debris. Once an old roof is removed, damage may also be uncovered that has to first be repaired, resulting in what may be unexpected expenses.

Location
Where you live will affect replacement roofing costs. The type of permits required, regulations that must be adhered to, and climate factors that affect roofing materials and installation processes will factor into the cost. For example, if you need to add hurricane bracing or straps or ice breaks to the roof, this will add to the installation costs. Permits alone may run a few hundred dollars and town ordinances may dictate what type of roofing materials you are allowed to use on your home, affecting the price. Pricing also varies by location simply due to regional differences and price tolerances.

Size
Most replacement roofing costs are calculated per square – that is for a 10′ by 10′ section – or you may receive a roofing quote for the whole project. Either way, the cost will be determined in part by the size of the roof. To get a rough idea of how many square feet your roof is, you can take the number of square feet you have inside the house and multiply it by 1.5. This will only give you a rough estimate, since the style of roof will alter how much roofing coverage your need, but will let you be more prepared for the amount of roofing you need to replace.

Extras
Replacement roofing costs will be affected by all the extras that may be required during the installation process. If you need new flashing, whether around a chimney, skylight or valley roof, that will cost you additional materials and labor. If you have solar panels, skylights, multiple dormers or other features on your roof, that will add to the complexity of the installation and may increase the cost. If you have large trees that hang over the roof, you may need to have them pruned before installing the new roof.

Estimate Basics
Each roof replacement job will be different depending on the needs of the roof, the type of material, and whether the existing roof will need to first be removed. As a general guideline, however, you can expect a roof replacement installation to include the removal of existing roofing (including disposal of the debris), the installation of new roofing material, and the sealing of any cracks or edges. Extras can include installation of flashing, repair of roof due to leaks, repair or replacement of gutter systems, installation of attic vents or attic insulation, as well as other options. When comparing replacement roofing prices from contractor to contractor, be sure you are comparing similar services and materials.
