Roofing Manufacturers
The spec names a maker, and the maker's published details become the bid. Flashing heights, fastener patterns and seam methods all come from that document. In Bellingham, WA the same details have to survive 67 mph gusts, damp decks that dry slowly and a dry season that runs thin after July. We read the maker's method, then plan it around the weather.
We install, repair and maintain the system types below. Each maker below is a system category we know how to run on a local roof.

Good to Know Before You Call
Single-ply makers
Carlisle SynTec and Versico sell single-ply sheets in the rubber and thermoplastic families. Holcim Elevate, formerly Firestone Building Products, sells the same families with metal and insulation alongside, and the name change matters when you read old warranty paper. Sika Sarnafil is known for welded PVC.
Within these families the field craft is the same: a clean, dry surface, a probed seam and a tested flashing. Brand sets the accessories and the published details, and the crew sets the quality.
Broad lines
GAF and Johns Manville span single-ply, bituminous and insulation categories, which suits a campus with several roof types. Soprema centers on modified bitumen and liquid-applied details. Duro-Last fabricates PVC panels off site to the roof's measurements.
Matching the maker to the roof
Four questions lead. What is under the roof today, and is it dry? What vents onto the roof? What does the wind rating require at the corners? And what is the lead time against the dry-in date? Prefabricated panels need a survey months before the install. Metal needs coil ordered ahead. A single-ply order can be quicker, but accessories still gate the flashing day.
Insulation is part of the match. A replacement stack now carries more board than the old roof did, because the 2021 energy code took hold in March 2024. Longer fasteners and taller flashings follow, and the submittal confirms them.
What the local roof demands
Rain adds up to roughly 34.8 inches in a Bellingham year, and with sun near 1,866 hours the decks dry slowly. Welded seams, adhesives and coatings all need a dry surface, so the install window follows the calendar. Roofs along Marine Drive add salt to the hardware list. Roofs near PeaceHealth St. Joseph add shutdown windows.
Commercial Roofing Questions
Does the maker change how a repair is done?
The sheet type changes the method more than the name. Rubber gets primed and taped. Thermoplastic gets cleaned and welded. We identify the sheet with a sample before touching it.
Can parts from different makers share one roof?
Sometimes. The assembly rating and warranty terms may change, so the design team confirms the combination before we order.
Why do old warranty papers carry a different name?
Companies rename. The terms in the document still govern. We record both names in the roof file and keep a copy of the certificate.
How early should the maker be named?
As early as the design allows. Submittals, lead times and accessory lists all start from the named system, and a late change can push a summer job into the wet season.
Send the spec and the named system
Send the drawings, the roof spec and the maker named in the design. We will price the sheet, the accessories and the install window as separate lines before the bid closes.
