Complexity of Roof System – The more complex the roof system is, the higher the costs associated with the project. Complexity increases when the roof is highly penetrated or there are unique details associated with the installation of the roof system.
Increased Insulation Requirements – The more insulation that is required, the higher the costs associated with the roof installation. Building use and building location affect the demand for insulation and R-value. Increases in insulation thickness also lead to increased fastener length which may impact the roof project cost.
Increased Fastening and Securement – Buildings located in areas of the country with high wind exposures require increased securement. Increased securement of the roof system leads to higher material and labor costs associated with the project.
Roof System Type – Depending on the building use and the roof system requirements, certain roof system types may be required. Different roof system types have different price points that will affect overall roof system pricing.
Removal vs. Retrofit – In some situations, the roof system being installed may be able to be installed over the existing roof system. As a result, the costs associated with a complete removal of the existing system may be avoided.
