When it comes to replacing your flat roof, you need to think long-term. Getting a cheaper roof, such as EPDM Rubber, may be appealing at first, but if you are looking for a long lasting, durable, leak free, energy efficient and low maintenance roofing membrane, an IB PVC Roof is the best choice.
IB is a premium product and costs more than most other flat roofing materials. Here we review flat roofing cost structure and, IB Roof prices and packages that we offer in Massachusetts and surrounding states ( CT, RI, NH, ME and VT).
Flat Roof Replacement Cost: Residential and Commercial
At some point, there comes a time when flat roof patches stop working and it needs to be replaced. Installation price from every roofing company also includes that company’s overhead or cost of running the business. An established roofing company should be fully insured.
This includes adequate Liability and Worker’s Comp Insurance. If, for example, you get a very low bid, consider that the bidder might not be adequately insured or have no insurance at all. If that is the case and you hire such a contractor, you will be responsible for any damages or injury claims that may occur.
Our general pricing for flat roof replacement works in the following manner:
Residential flat roofs are priced at $675 per square for a simple roof, with no existing roof removal. This includes 50-mil IB Roof membrane, 1/2 inch foam insulation with 2 r-value, perimeter pressure-treated wood nailer and half-roll membrane around the roof edges for wind-uplift prevention.
Roof attachment using heavy-duty screws and barbed plates, 6 inches O.C. along the perimeter and 12 inches O.C. in-field. All required roofing parts and accessories are included.
Generally, for a 1000 sq. ft. residential home, your cost should be around $6750 for an average (simple) roof. If you would like to upgrade the membrane type or add more insulation, this will slightly increase your price. Please note: For all residential installations, all IB roofing membranes come with a lifetime residential warranty, therefore there is no need to upgrade from 50 to 80-mil product, as both will perform equally well in protecting your roof from the elements, and will remain water-tight throughout their service life and beyond.
