Re-roofing starts with what is already there

By Jesse Sanchez.

A successful re-roofing project begins with understanding the existing roof, the building’s operations and the owner’s long-term expectations.

Choosing the right re-roofing system is rarely a one-size-fits-all decision. For Ken Gingerich, manager of the project review team at Versico Roofing Systems, the process starts with a thorough evaluation of the building and a clear conversation about what the owner expects from the new roof. Highlighting the range of factors that can influence a project, Ken explained, “You have to look at what is the existing roof type? How long has it been in place? What are the building owner's needs?”

That evaluation should also extend beyond the roof itself. Contractors need to understand what is happening inside the building, including whether fasteners, noise or changes in dew point could affect ongoing operations. Once a tear-off begins, previously hidden conditions can further change the scope of the project. A core cut may show one type of deck in one area while another section contains a different deck or concealed deterioration. Emphasizing the value of preparation, Ken said, “I think that the more thorough somebody can be up front, the better it's going to be for them.”

Preparation should also include conversations about insulation, expected roof life and project logistics. Owners may want a 10-year system or expect the roof to perform for 30 years, making it important to establish those expectations before materials arrive on site. Contractors also need to plan dumpster placement, paths of travel and how tear-off work could disrupt the building interior.

Communication becomes especially important when deciding between a re-cover and a complete tear-off. Contractors can help owners understand those recommendations by documenting roof conditions and clearly explaining what they find. Expressing the importance of transparency, Ken advised, “Being frank and honest with the owner could be paramount as to whether you win the project, whether you're low bid or not.”

Collaboration among contractors, designers and building owners can also help align priorities involving cost, code compliance, insulation performance and long-term plans for the building. Continued education through industry organizations, local chapters and professional forums can further help roofing professionals strengthen their decision-making and project planning.
