What Our Commercial Roof Installation Service Includes

A commercial roof installation is more involved than simply placing material on a building. Our process starts before we ever set foot on your property, with a thorough assessment of the building structure, slope, drainage requirements, and any rooftop equipment that needs to be integrated into the system.

Site Assessment and Measurement: We take precise measurements and evaluate the deck condition, structural load capacity, drainage configuration, and local building code requirements before recommending a roofing system.

Material Selection: Based on your building type, budget, and performance needs, we help you choose the right system. Options include TPO, EPDM, metal, modified bitumen, and built-up roofing. We explain the differences in plain language so you can make a confident decision.

Installation: Our crews follow manufacturer installation guidelines to ensure your warranty remains valid. We use proper adhesives, fasteners, and seaming techniques for the system being installed, and we take care around rooftop penetrations, drains, and edges, which is where failures most commonly start.

Final Inspection and Documentation: Once installation is complete, we walk the roof with you, document the finished system, and provide warranty paperwork. We want you to have a clear record of what was installed and what is covered.

Flat and Low-Slope Roofing Systems

The majority of commercial buildings use flat or low-slope roofing systems, and this is where our installation crews have the most depth of experience. Unlike steep-slope residential roofs, flat and low-slope systems require careful attention to drainage design and membrane integrity to prevent ponding water and leaks over time.

We install TPO and EPDM membranes using both mechanically fastened and fully adhered methods, depending on the substrate and application. Heat-welded seams on TPO systems create a bond that is often stronger than the membrane itself when done correctly. EPDM systems offer excellent flexibility in cold weather and a long track record of performance in the Midwest climate.

For buildings that need additional durability, we also install multi-ply modified bitumen and built-up systems that hold up well to foot traffic and heavy rooftop equipment loads. During planning, we account for proper slope and drainage so water moves off the roof efficiently rather than sitting and causing long-term damage to the structure below.

If your building already has an aging flat roof system that needs to come off before a new one goes on, visit our commercial roof replacement page to learn how we handle that process.

Metal Roofing for Commercial Buildings

Metal roofing has become a popular choice for commercial buildings because of its long service life, low maintenance requirements, and strong performance in harsh weather. A properly installed metal roof can last 40 years or more, making it one of the most cost-effective options when you look at the full picture over time.

We install standing seam metal systems, which feature raised seams that run vertically along the roof and keep fasteners hidden from the elements. We also install through-fastened metal panels for applications where budget is the primary constraint and the slope of the building allows for it. Both systems are available in a range of colors and finishes to complement your building’s exterior.

Metal roofing works well on commercial buildings with moderate slopes, warehouses, agricultural structures, and certain retail and industrial applications. If you are not sure whether metal is the right fit for your building, we will help you weigh the options during our initial assessment. You can also browse our project gallery to see examples of completed commercial work.

Already have a metal or flat roof showing signs of wear? Our commercial repair team handles leaks, seam failures, and storm damage on all the systems we install.

Frequently Asked Questions

How long does a commercial roof installation take? Project timelines vary based on building size, roofing system, weather, and site conditions. A small to mid-size commercial installation typically takes anywhere from a few days to a couple of weeks. We provide a project timeline estimate before work begins and keep you updated throughout so there are no surprises.

Do you handle permitting for commercial installations? Yes. We manage the permitting process as part of our installation service. Our team is familiar with local building codes across Michigan, Ohio, and Indiana, and we make sure the required permits are pulled and inspections are scheduled at the right stages of the project.

What happens if the decking underneath is damaged? During our site assessment, we inspect the deck for soft spots, rot, or structural compromise. If we find damage, we include deck repair or replacement in the project scope and pricing before installation begins. We will not install a new roofing system over a compromised deck.

Can I choose the roofing system or do you recommend one? Both. We make a recommendation based on your building’s characteristics and your goals, but the final decision is always yours. We explain the advantages and trade-offs of each option so you have the information you need to choose with confidence.

Is financing available for commercial roof installation projects? Yes. We offer financing options to help make larger commercial projects more manageable. Visit our financing page to learn about current programs, including 0% APR options for qualified applicants.
