Owens Corning Preferred Contractor — St. Louis, MO

Owens Corning Preferred Contractor in St. Louis, MO

St. Louis Roofing & Siding is an Owens Corning Preferred Contractor — authorized to install Owens Corning’s full premium shingle systems and back the work with an extended system warranty covering both materials and workmanship.

What Preferred Contractor Status Means

Why Owens Corning Preferred Matters for Your Roof

Owens Corning doesn’t hand out Preferred Contractor status to every roofing company that asks. It’s awarded to a select group of contractors who meet standards around licensing, insurance, training, and a track record of quality installations. It’s Owens Corning’s way of telling homeowners which contractors it trusts to install its products correctly — because a premium shingle installed incorrectly performs like a cheap one.

The practical benefit for you: Preferred Contractors like St. Louis Roofing & Siding can offer extended manufacturer-backed warranty options that cover both materials and workmanship — not just the shingles themselves. That’s only possible when the full roofing system (shingles, underlayment, starter strip, ridge cap) is genuine Owens Corning product installed by a contractor authorized to back it with that warranty.

For St. Louis homeowners dealing with hail-prone weather and comparing quotes from multiple contractors, Owens Corning Preferred status is one of the clearest, most verifiable signals of installation quality — you can confirm it directly on Owens Corning’s own contractor locator, not just take a contractor’s word for it.

Common Questions

Owens Corning Preferred FAQ

What does “Owens Corning Preferred Contractor” actually mean?
Owens Corning Preferred Contractor is a status awarded to a select group of roofing contractors who meet Owens Corning’s standards for training, licensing, insurance, and customer satisfaction. It is not a fee-only designation — contractors must demonstrate installation competency and maintain it to keep the status. Owens Corning uses it to signal which contractors it trusts to install its products correctly.
Do I get a better warranty with an Owens Corning Preferred Contractor?
Yes. Preferred Contractors can offer extended manufacturer-backed warranty options that cover both materials and workmanship, which typically aren’t available through non-preferred installers. That coverage requires installing a full Owens Corning system — shingles, underlayment, starter strip, and ridge cap all from Owens Corning — rather than mixing brands.
Does an Owens Corning Preferred installation cost more?
Material costs are comparable to other premium shingle systems on the market. Any cost difference usually comes from installing the complete Owens Corning system rather than mixing in cheaper third-party components, which is what’s required to qualify for the strongest warranty coverage. We’ll give you a written estimate so you know exactly what you’re paying for.
How do I confirm a contractor is really Owens Corning Preferred?
You can search Owens Corning’s official contractor locator directly on owenscorning.com, or simply ask the contractor for their Preferred Contractor ID. We’re happy to provide ours on request — verifying this directly with the manufacturer is the most reliable way to confirm any contractor’s claim.
What Owens Corning products does St. Louis Roofing & Siding install?
We install Owens Corning’s TruDefinition line of architectural shingles along with matching Owens Corning underlayment, starter strip, and ridge cap components. Installing the full matched system — not just the shingles — is what qualifies a job for extended warranty coverage from Owens Corning.
