Owner-attested attendance. GACO / Firestone does not typically issue individual certificates for product-knowledge sessions. Listed as training attended, never as certification.
What we check on a GACO / Firestone install
- Coatings are a maintenance system, not a replacement — recoat every 8–12 years.
- Silicone > acrylic for NM UV, but silicone won't recoat with acrylic later.
- Prep is 80% of the job — power wash, prime, reinforce seams before spraying.
- Mil thickness matters — 20-wet-mil silicone is the standard spec.
- Manufacturer warranty requires their exact system, applied by their approved applicator.
Questions to ask any contractor bidding GACO / Firestone on your roof
- Are you a GACO / Firestone-authorized installer? Can you register the manufacturer's system warranty on my roof?
- Which GACO / Firestone product line are you installing? What's the exact spec — nailing pattern, underlayment, accessories?
- Will you supply photos of critical details (valleys, penetrations, flashings) before dry-in and after tear-off?
- Does the GACO / Firestone warranty on this bid cover material only, labor + material, or full system with workmanship?
- What's your written policy if a GACO / Firestone warranty claim is denied later because install spec wasn't met?
