GAF vs Owens Corning Roofing in Longmont, CO — What Certifications Actually Mean (2026)

By /
Josh Brooks Construction and Renovation Inc. | Longmont, CO 80501 | 📞 720-828-7997 | 📱 720-453-5095 GAF and Owens Corning are the two biggest names in roofing materials — and Longmont contractors like WestPro (GAF Master Elite) and GreenPoint Roofing (Owens Corning Platinum Preferred) build their entire identity around these certifications. Here’s what those certifications actually mean for you — and why the contractor matters more than the brand.

GAF Master Elite Certification — What It Actually Means

GAF is the largest roofing manufacturer in North America. Their Master Elite certification is awarded to contractors who meet requirements for licensing, insurance, continuing education, and warranty eligibility. Only about 2% of roofing contractors qualify nationally. Benefits of a GAF Master Elite contractor:
  • Access to GAF’s strongest warranties (System Plus, Silver Pledge, Golden Pledge)
  • Contractor has passed GAF’s training and licensing requirements
  • Eligible to offer factory-backed warranties
What it doesn’t guarantee:
  • Communication quality
  • Response time
  • Honest pricing
  • That the owner answers the phone

Owens Corning Platinum Preferred — What It Actually Means

Owens Corning’s Platinum Preferred designation (held by GreenPoint Roofing) is their top contractor tier, requiring proof of licensing, insurance, and adherence to installation standards. It enables access to Owens Corning’s strongest warranties including their Total Protection Roofing System.

Does the Brand Certification Matter for Hail Damage Claims?

Honestly — less than you’d think. In Colorado’s hail corridor, most insurance-funded roof replacements use standard architectural shingles from GAF, Owens Corning, CertainTeed, or Atlas. All of these brands make Class 4 impact-resistant shingles that qualify for insurance premium discounts. The brand your contractor prefers affects warranty terms — but in a hail-prone state like Colorado, you’re more likely to need another full replacement in 15-25 years regardless.

What Matters More Than Brand Certification

  1. Does the contractor answer the phone? Josh does. Personally.
  2. Are they locally owned and actually in Longmont? Josh lives here.
  3. Do they handle your entire project or just the roof? Josh handles everything.
  4. Are they licensed and insured in Colorado? Josh is.
  5. Do they offer Senior & Veteran discounts? Josh does — automatically.
  6. Are they available 24/7 during storm season? Josh is.

Class 4 Impact-Resistant Shingles — The Smart Choice for Longmont

Regardless of brand, Class 4 impact-resistant shingles are the best choice for Longmont’s climate. They are rated UL 2218 Class 4 — the highest impact resistance rating available. Benefits include:
  • Significantly better hail resistance than standard shingles
  • Insurance premium discounts of 15-30% from most Colorado insurers
  • Longer effective lifespan in Colorado’s hail corridor
  • Available from GAF, Owens Corning, CertainTeed, and other brands

Roofing in Longmont: Frequently Asked Questions

How much does a roof replacement cost in Longmont?

Roofing is priced per square (100 square feet): Class 4 impact-resistant shingles run about $1,000 per square, metal about $1,200 per square and concrete tile about $2,000 per square. Every replacement includes all new metals and flashing. The total depends on roof size, pitch, layers to tear off and the material you choose.

What shingles does Josh Brooks Construction install?

We install only Class 4 impact-resistant shingles, Owens Corning Duration STORM or better, because Colorado hail destroys standard shingles. Every roof gets all new metals and flashing rather than reused parts.

Does a Class 4 roof lower my insurance premium?

Many Colorado insurers offer a premium discount for Class 4 impact-resistant roofs. Ask your agent what your carrier gives; we can provide the product documentation they ask for.

Is Josh Brooks Construction a licensed contractor?

Josh Brooks Construction and Renovation Inc. holds a Boulder County contractor license (CON-24-0152, Class C), a Jefferson County Class C license and a Douglas County Class A license, and pulls the building permits the job requires.

Colorado Class 4 shingle insurance discount: what the law says

  • Colorado law (CRS 10-4-110.8) requires insurers to factor impact-resistant roofing into their premium rates — the legal basis for the Class 4 discount.
  • In June 2026, SB26-155 created the Strengthen Colorado Homes Enterprise; starting 2027, insurers must prove resilient-roof savings actually reach homeowners.
  • Carrier discounts typically run 15–35% (about 28% on average), applied to the dwelling or the wind/hail portion of the premium.
  • Class 4 is the top rating under UL 2218: a 2-inch steel ball dropped 20 ft must not crack the shingle.
  • The upgrade typically pays for itself in roughly 3–7 years through premium savings.
