Buying a new roof can be stressful. Afterall, it's not something you do everyday and most likely, you're not well versed on "all things roofing." Hopefully, this information will help you understand how roofing companies price a new roof so you are prepared when meeting with contractors.
There are many factors that affect the decision-making process for selecting your roofing contractor, such as reputation, license and insurance. However, the scope of work, roof materials used, bid details and cost to complete the roofing project are ultimately the most important factors.
Roofers charge per roofing square. A 10-by-10-foot (100 square feet) area is equal to one roofing square. They calculate the square footage of your roof and then divide this number by 100, giving them the roofing squares.
The roof’s pitch - how steep it is - is an important factor in determining roof cost for two reasons: ease of installation and safety. A very steep roof, typically anything that’s more than 6:12 pitch, is generally considered not walkable and requires greater staging, safety and labor to complete the roof properly.
Depending on the type of roof being installed and the required fire rating, roof pitch determines the type (and cost) of underlayment system required.
The cost of roof tear-offs is determined by the amount of time it takes to remove — the labor — and the cost of proper disposal of the roofing material, which is typically determined by weight. The heavier the material or the more there is, the time and disposal costs increase.
As covered in the benefits and disadvantages of the different roofing materials, the price of the roofing product being used plays a direct role in the aesthetic design, weight, durability and ultimate longevity of the new roofing system. For sloped roofing products, the least expensive is asphalt composition shingles, then concrete and clay tile, with synthetic, wood shake, metal roofing and traditional slate being in the higher range. For flat roofs, pricing options tend to start with coatings, hot-mop built-up roofs, modified torches, TPO products and finally single-ply PVC systems.
Most people think of their new roof simply as the new tile or shingle which is being applied; however, there is much more to waterproofing your roof over the long-term. The type of underlayment and decking materials used, the ventilation and insulation installed and even the types of fasteners applied all carry a different level of performance, longevity, manufacturing cost, and thus price. When comparing quotes, make sure you’re comparing apples-to-apples.
Access to the roof is a critical aspect in calculating labor and equipment costs of the job. Difficult access means additional equipment and labor are necessary to tear off the roof, load the roofing materials, stage the roof and complete the roof system. The easier the access, the less time and material are necessary to complete the job.
There is a standard roofing warranty where the roofing contractor backs the labor and workmanship of the project. J.P. Witherow Roofing offers a 5-year residential warranty plus the manufacturer’s warranty. A manufacturer’s warranty typically requires additional steps, materials and inspections along with a fee that is charged by the manufacturer to back and support the roofing contractor’s labor and workmanship.
Manufacturer-warranted roof replacements typically feature higher quality workmanship, since they bring an added set of eyes on the inspection and ultimately more security and peace of mind to the consumer. J.P. Witherow Roofing is a Certified Applicator for Owens-Corning, so we can give a little bit better warranty than other contractors. We also have lifetime warranty options that are transferrable one time.
There are several finish details and prep details that certainly affect the cost of the roofing job. For instance, the type and quality of the lumber being used for fascia and rafters, along with the finishing sealants and counter-flashing details all play a critical role in not only the look of your finished roof, but the cost.
