Is Roof Doctor NM Lomanco certified?

No — we've attended in-person Lomanco product-knowledge training (Southwest regional), but Lomanco 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 Lomanco install?

We check the finished roof against Lomanco's published install spec — nailing pattern, flashings, underlayment, accessories, and warranty registration paperwork. OmniRoll ridge vent + intake spec

Should I hire a Lomanco-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 Lomanco warranty requirements.

Ridge & static vents — inspector's-eye notes on install spec, warranty requirements, and what typically gets skipped on NM installs.

Owner-attested attendance. Lomanco does not typically issue individual certificates for product-knowledge sessions. Listed as training attended, never as certification.

What we check on a Lomanco install

Balanced intake (soffit) + exhaust (ridge) — one without the other doesn't work.
Net free area (NFA) calculated to the attic square footage — not just "add a vent."
Never mix ridge vent with power/gable vents on the same roof plane — short-circuits airflow.
Baffles at every soffit bay so insulation doesn't block the intake.

Questions to ask any contractor bidding Lomanco on your roof

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