At that time, many people were concerned that a single layer of protection would be prone to leaks. Viable single-ply materials first became available for flat roofs about 25 years ago. In the majority of cases, the best roofing material for a flat roof is either a single-ply roof or built-up bituminous roofing. There are two main categories of commercial roofs: In this article, we’ll discuss the top five factors that will impact the cost of your commercial roof replacement: Understanding the primary cost factors involved in a commercial roof replacement can help in that decision, as well as in deciding what type of replacement to choose and how much to budget. For that reason, when a problem arises, the building owner should first consider whether to repair rather than replace. It’s also noteworthy to report that industry studies have found as much as 80% of roofs are replaced prematurely ( RoofCare 2009, Association of Physical Plant Administrators, Alexandria, VA.).The roof is one of the most important, and also one of the most expensive, components of any building. Likewise, other industry studies found on more complicated re-roofing projects, costs could vary from $7.00-$12.00/square foot. According to consulting firm Benchmark, on the majority of retail projects it’s examined, re-roofing costs ranged $3.50-$6.50/square foot. One study found on a roof with average dimensions of 10,000 square feet, a new commercial roof can cost over $4.25/square foot. In general, re-roofing costs can vary greatly. Also, it’s more accurate to have a per-square-foot rate for estimating re-roofs on many building assets instead of just on one facility. Ultimately it boils down to many factors: the extent of tear-off needed, new material costs, how long the project will take, how many penetrations your rooftop has, your roof’s pitch, and other dimensions. It’s hard to estimate how much a commercial re-roofing would cost.
