There are significant differences between different types of materials. The cost of the roofing material used has a direct impact on the new system’s aesthetic quality, weight, reliability, and ultimate lifetime. Asphalt composition shingles are typically the entry level product for steep roofing, with potential lifetime shingle product options requiring a higher cost. Concrete and clay tile are typically more of a mid-range option, whereas synthetic, wood shake, metal, and traditional slate are more expensive options.

Coatings, hot-mop built-up roofs, adjusted torches, TPO products, and single-ply PVC systems are the most popular flat roof pricing choices.
Roof slope and/or pitch
The pitch of the roof is important in deciding the cost for two reasons. The first is that a very steep roof, defined as anything with a pitch greater than 6:12, is generally considered unwalkable and necessitates much more protection, labour, and staging to complete properly.
Roof pitch specifies the type of underlayment system required based on the type of roof being built and the required fire rating, and it plays an important role in properly estimating a roofing job throughout these lines
A composition shingle roof with a pitch of 2:12 to 4:12 requires two layers of underlayment, while a flat roof with a pitch of 1/2:12 to 2:12 can require specific underlayments to achieve a Class A fire rating.
The roof’s size
Roofing contractors would take an accurate roof calculation based on square footage and then divide the amount by 100, giving them what is known as a roofing square. 100 square feet is equivalent to one roofing square. The majority of roofing materials are sold in squares rather than square feet.
