Lansing’s commercial buildings range from mid-century government offices near the Capitol to newer manufacturing and distribution facilities along I-96, and most carry flat or low-slope roofs with a direct effect on heating and cooling costs. For property owners evaluating commercial roofing companies in Lansing, MI, how a contractor’s system recommendations affect energy performance is as relevant as how they affect service life.

How Commercial Roofing Companies Affect Energy Performance
The roof assembly is one of the most significant components of a commercial building’s thermal envelope. Membrane material, insulation type and thickness, attachment method, and the condition of that assembly over time all affect heat loss in winter and heat gain in summer. Lansing’s climate makes both directions relevant. Reflective white membranes, such as TPO and PVC, reduce solar heat gain on summer afternoons when the occupied space sits below the roof deck. The surface temperature difference between a reflective and an absorptive membrane translates directly into cooling load. Commercial roofing companies that understand this specify membrane reflectivity as part of the performance conversation, not as a secondary consideration.
Insulation: The Energy Variable Most Often Underspecified
Insulation is where energy performance is most often compromised in commercial roofing projects. The insulation layer beneath the membrane governs how quickly heat moves through the roof deck in either direction. Contractors who specify minimum insulation thickness to hit a price point are reducing the building’s thermal resistance for the life of the roof.
Moisture in the insulation layer compounds the problem. Wet insulation loses R-value. A roof installed with adequate R-value that develops moisture intrusion early delivers less thermal resistance than specified, and that shortfall shows up on the utility bill every month. Commercial roofing companies that conduct core sampling on re-roofing projects to confirm insulation dryness are protecting the energy performance of the new assembly from day one.

What to Ask About Energy Performance When Comparing Companies
When reviewing proposals, ask each contractor to specify the insulation system by type and R-value, not just thickness. Ask about membrane reflectivity and whether the specification accounts for the building’s cooling load. Ask what the proposal does if core sampling reveals moisture in the existing system. A contractor who cannot answer those questions specifically is treating the roof as a commodity, not a building system with measurable performance implications. Also ask whether the proposed system qualifies for any Michigan utility rebate programs for high-reflectivity or above-code insulation specifications.

FAQ
Does a white roof membrane actually reduce energy costs for a Lansing commercial building?
Yes, on buildings where the conditioned space sits below the roof deck. A reflective membrane reduces peak cooling demand in summer, which affects both utility costs and HVAC runtime. The effect is less significant on unconditioned warehouses or buildings with heavy insulation between the deck and occupied space. For office buildings, healthcare facilities, and retail spaces in Lansing, membrane reflectivity is a real performance variable worth specifying.
How does insulation thickness affect energy performance on a Lansing commercial roof?
A higher R-value slows heat transfer through the roof assembly in both directions, reducing heating loads in winter and cooling loads in summer. Most Michigan commercial roofing specifications target R-25 to R-30 for new installations, though older buildings being re-roofed often have less. Adding insulation during a planned re-roof is cost-effective because the labor is already mobilized. The incremental cost of additional insulation during a re-roofing project is small relative to what a standalone insulation project would cost.
Can spray foam roofing improve energy performance in an older Lansing commercial building?
Spray polyurethane foam delivers some of the highest R-values available in commercial roofing, and its seamless application eliminates thermal bridging at fasteners and seams common in mechanically attached single-ply systems. For older Lansing buildings with minimal insulation or irregular roof decks, spray foam can improve thermal performance while addressing drainage and penetration flashing in a single application. It is not the right system for every building, but for candidates it combines insulation, waterproofing, and air sealing in one pass.
