Fit-out work cannot simply be applied to any roof, by any roofing firm. Before conducting any solar, green, HVAC, ventilation, signage, or other fit-out work over an existing roof system, building owners must consider many factors not just to properly install a functioning system, but avoid voiding their roof’s warranty or endangering workers.

The key to solving these problems is to team with an experienced commercial roofer who understands the ins and outs of every roof system and ALL fit-out work. Roof device manufacturers recommend that a roof substrate evaluation be performed before any fit-out work is performed. During this evaluation, your roofing contractor should be making core cuts into the membrane of your existing roof system to be sure it can support whatever work is necessary for your building envelope. You should also keep in mind that fit-out work often means additional roof system penetrations, increased rooftop traffic, and increased surface temperatures.

After an evaluation, it is critical that building owners work with that certified commercial roofer to prepare a plan of action. This creates professional contact between the manufacturer and building owner and eliminates any risk of violating regulations or voiding an existing roof warranty. Moreover, a certified roofer understands that any new anchor points need to be specified and approved by the manufacturer before being cut into the membrane. The contractor is also able to address the necessary repairs required before the fit-out work can begin.

Finally, after all fit-out work has been completed, a new safety audit is required. Any new construction on and around your roof system often means that access points, walk paths and exit hatches on the existing roof system may be relocated. To comply with OSHA regulations and safety standards, walkways on top of the roof system and safety rails surrounding its barriers often need to be reconfigured.

Investing in fit-out work to improve your building envelope is a great functional benefit to almost any commercial building. However, doing so without adhering to the proper guidelines could put your roof warranty and building envelope safety at risk. Be sure to always create a plan of action before choosing beginning work on your roof, to keep you and everyone who utilizes your commercial space dry and safe.
