Is Roof Doctor NM Karnak certified?

No — we've attended in-person Karnak product-knowledge training (Southwest regional), but Karnak generally does not issue individual "certified" credentials for product training. We list this as training attended, never as certification. That distinction matters and we keep it strict.

What do you look for on a Karnak install?

We check the finished roof against Karnak's published install spec — nailing pattern, flashings, underlayment, accessories, and warranty registration paperwork. Fibered aluminum, silicone, and mod-bit patch products

Should I hire a Karnak-authorized contractor?

For system warranty coverage (like GAF Golden Pledge or Owens Corning Platinum), yes — only manufacturer-authorized installers can register those warranties. For the roof itself, install quality matters more than the badge. We'll tell you honestly whether the bid you have satisfies the Karnak warranty requirements.

What we check on a Karnak 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 Karnak on your roof

Are you a Karnak-authorized installer? Can you register the manufacturer's system warranty on my roof?
Which Karnak 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 Karnak warranty on this bid cover material only, labor + material, or full system with workmanship?
What's your written policy if a Karnak warranty claim is denied later because install spec wasn't met?
