Is Roof Doctor NM Grace / GCP Applied Technologies certified?

No — we've attended in-person Grace / GCP Applied Technologies product-knowledge training (Southwest regional), but Grace / GCP Applied Technologies 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 Grace / GCP Applied Technologies install?

We check the finished roof against Grace / GCP Applied Technologies's published install spec — nailing pattern, flashings, underlayment, accessories, and warranty registration paperwork. Grace Ice & Water Shield — self-adhered valley/eave protection

Should I hire a Grace / GCP Applied Technologies-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 Grace / GCP Applied Technologies warranty requirements.
