When it’s time to replace your commercial roof, understanding what’s involved in the installation process is critical. An informed business owner makes smarter decisions and avoids surprises. Let’s walk through the key phases of commercial roofing installation so you know what to expect for your next project. Initial Inspection and Analysis The first step a professional commercial roofing company in West Allis, WI will complete is a detailed inspection and analysis of your existing roof. This allows them to gauge necessary repairs, determine if replacement is needed, and select optimal new materials. They should evaluate the roof structure, drains, flashings, parapets, and mechanical equipment. Be sure they outline the full scope of work so you understand the recommendations. Permitting Your contractor will pull all necessary permits for commercial roof demolition and installation required by your city or county. This ensures the project meets building codes and legal requirements. Depending on the jurisdiction, this may require submitting drawings, forms, notices, and fees before work can begin. Trust your contractor to navigate local permitting correctly. Tear-Off and Deck Preparation Once permitting is complete, the tear-off of the old roof can commence. This entails removing and disposing of existing membranes, insulation, flashing, drains, and roof decks. The crew will ensure no water infiltrates the building during removal. Once bare, the deck is prepped and repaired if needed to create a smooth substrate for the new roof.

This provides a base to control moisture and strengthen the assembly. Look for materials that offer a combination of insulation and protection in one. Other components, like tapered insulation, improve drainage. Membrane and Flashing Installation With the deck prepped, it’s time to install the new roofing membrane, which creates the all-important waterproof seal. Seek out options that offer durability and energy efficiency. Critical flashing components are also reinstalled around drains, vents, and roof edges. This shields vulnerable transition areas from leaks. Completion and Inspections Finally, crews will complete detailed work like replacing drains, counterflashing, and installing walkway pads. Local building inspectors then verify all work meets code compliance and issue permits. The roofing company will also review their warranty coverage with you, provide safety information, and review any maintenance recommendations. With those final steps completed,...
