Manufacturer requirements matter
Warranties and approvals depend on substrate condition, fastening, insulation, edge details, sheet layout, accessories, and documented installation. We keep those requirements connected to the roof scope instead of treating them as paperwork after the fact.
That helps owners compare systems on real performance and project fit.
The building still decides the system
A brand name is not a substitute for moisture review, drainage planning, deck evaluation, and correct detailing. We match manufacturer options to the roof, the budget, and the operational constraints of the property.
The manufacturer pages below give a starting point for that comparison.
