Roof access is one in a series of concerns for managers seeking to minimize foot traffic and potential damage.

Contractors typically offer several different types of roof warranties. Membrane-only warranties cover membrane failure only and do not include any labor costs for repair work. If labor costs are included, it might only be in the event that the membrane requires replacement.

The most common warranty is a no dollar limit (NDL) warranty, which can be 10-, 15- or 20-year full replacement cost and should be non-prorated. At the time of proposal submission, the contractors should submit a sample copy of the manufacturer’s warranty. 

There are options for warranties that are longer than 25-30 years, but these roof systems typically require upgraded materials and details, which can be more expensive. Managers should talk with the owner and, if appropriate, a roof consultant to determine if the additional cost aligns with the long-term goals of the project. 

Beyond installation

Once the replacement project is complete, it is time to maintain the investment. It is in the best interest of the manager and the organization to work with the installing contractor on a maintenance contract since they typically are responsible for workmanship repairs for the first two-five years of a favorable warranty. The industry has been on a spring and fall maintenance cycle, but managers should negotiate this point at the time of contract for the new roofing system, since this can be a great bargaining tool to get a reduced rate for inspections. 

If the budget allows, a manager should work with a Registered Roof Consultant to assist with conducting a preliminary assessment – see the sidebar – preparing construction documents, and performing construction oversight to ensure the roofing system meets the installation and post-installation requirements.
