There is no such thing as a common roofing job, so any discussion about roofing expenses needs to point that out. There are many factors that will effect what a new roof cost might be including roof pitch and size, materials, damage level, accessibility and more.
Your neighbor may have totally different criteria for a new roof than yours. As an example, your roof could be more weather damaged and worn, besides the differences in pitch and size. Also, you might want to add additional features like solar shingles or dormer windows that allow more light into your attic.
The ease of access and the number of stories your property have will affect your estimate. If your property is two stories or more, your cost will be higher. Also, if the roofer has more difficulty getting to the roof, like if you have a townhouse or other type of property that attaches to another dwelling.
The pitch of your roof, whether it be steep or a mild slope will have an effect on your estimate. Likewise, if your roof has a large number of hips and valleys in its design, it will be more difficult to install. Style refers to the basic shape of your roof. If you have extra features built in to your roof design, like dormer windows, vent covers, chimneys, skylights, etc., that will make the difficulty factor rise and increase your cost.
Pricing can be affected by where you live, your geographic location, whether it be in a rural or urban location.
If you live in an area with extreme heat, heavy snowfall or high winds, your roof will need particular fortifications that will increase your costs.
There’s a lot of choices available to you regarding materials, depending on your budget and tastes. One thing to be careful of though. Be sure that , if you have chosen a breakable material, such as concrete or clay tile, you order enough material to allow for broken material during the installation process.
If your home is older, it may have some structural deterioration, which would mean an increase in your labor expenses.
Size and dimensions. You can get a rough estimate yourself by measuring the the perimeter of your home, but a professional will climb onto your roof and get precise measurements.
The steeper the pitch of your roof, the more expensive it will be due to the additional material needed.
Its less expensive to add a layer over the top of existing shingles. But, if you already have several layers of shingles, you may have no choice other than stripping them off first, which is called a “tear-off”. If you’re installing a particularly heavy material like slat or concrete tile, in addition to the tear-off, you may need to reinforce your trusses and roof structure. You’ll need to get rid of the old material and it will add significant labor hours to your project.
There are other, less predictable factors that can add to your cost. Your roofing contractor might find that your flashing is damaged or your roof decking has deteriorated and needs repair first, which will lengthen the time for the project and add additional expenses.
Getting quotes from several reliable roofing companies is the best way to find out what your new roof will cost. You should not be charged for an estimate by a legitimate, professional roofing contractor. If you get an estimate that seems substantially lower than the others, be wary. Its likely to produce a poor installation. Get references from any company that is giving you a quote and make sure you do your due diligence on those references. Go to your homeowners insurance policy and see if your new roof can be covered under the policy.
