Roofing Manufacturers in Dearborn, MI
Most commercial roofs in Dearborn, MI, already carry a manufacturer's system, and the repair that works depends on which one. A patch that suits one membrane can fail on another, and a seam method that holds on one sheet can damage a different one. We install, repair and maintain these systems, and each job starts with identifying what is on the roof.
Single-Ply and Reinforced Membranes
Several manufacturers make white and gray single-ply sheets for low-slope roofs. Carlisle, Versico, Sika Sarnafil and Duro-Last are among the manufacturers whose systems commonly appear on commercial roofs. The seam method, the attachment pattern and the flashing details differ, and a repair has to match them. A heat-welded seam, a bonded splice and a chemically fused lap each need their own tools, surface prep and cure conditions, and the wrong choice shows up as a lifted edge a season later.
Asphalt-Based and Multi-Layer Systems
GAF, Johns Manville, Soprema and Holcim Elevate make systems that span single-ply, modified bitumen, built-up and coating categories. Many older low-slope roofs show layers from several eras, and the manufacturer's rules apply to the newest layer and sometimes to the whole assembly. Where a recover is planned, the new membrane has to be compatible with what stays beneath it, and the manufacturer's rules say how.
Identifying the Assembly First
We start by identifying the membrane, the attachment, the insulation and the deck, using labels, records and a test opening where needed. Winter is hard on every system, with about 30.8 inches of snow a year and repeated freeze-thaw at the Dearborn station, so we note how each assembly is aging at seams, edges and curbs.
Warranty Paperwork and Repair Rules
Many manufacturer warranties set rules for who may repair the roof, which methods are allowed and when notice is required. We ask for the paperwork before work begins and follow its notice steps, so a repair stays within its terms. The findings sheet states which warranty steps were taken and which were not needed. Our warranty management work keeps those papers in the roof file.
Commercial Roofing Questions
Do you work on every manufacturer's system?
We install and repair a broad range of commercial systems. The first step on any roof is identifying what is there, then matching the method to it, since no repair method fits every sheet.
Will a repair void my warranty?
It can, if it ignores the manufacturer's rules. We read the paperwork first and record the notice steps and dates.
Can different manufacturers' layers share a roof?
Often they do on older roofs. We identify each layer and decide whether a repair or recover is compatible with what is below.
How do I find out what system I have?
Look for labels on seams and edges, check the roof file and send us photos. A test opening can settle what remains unclear.
Send the roof records you have
Share warranty papers, plans and photos. We will identify the assembly and recommend the repair method that fits it.
