What is the difference between a manufacturer warranty and a workmanship warranty?

A manufacturer warranty is provided by the company that made the roofing materials and covers defects in the product itself. A workmanship warranty comes directly from your roofing contractor and covers the quality of the installation. Correll Roofing Co. provides both, so homeowners are protected on all fronts.

Can my manufacturer warranty be voided, and if so, how?

Yes. Common causes of voiding a manufacturer warranty include improper installation (fasteners outside the nail zone, inadequate ventilation), mixing incompatible materials, pressure washing shingles, or applying non-approved coatings. Hiring a contractor who installs to manufacturer specifications keeps your warranty intact.

Does hail or storm damage affect my roof warranty?

Storm and hail damage is generally considered an external cause and falls under homeowner's insurance rather than the manufacturer warranty. Correll Roofing works directly with insurance companies on storm and hail claims to help homeowners document damage and navigate the claims process.

Is the Correll workmanship warranty transferable if I sell my home?

Transfer provisions vary by warranty document. Many manufacturer warranties are also transferable to a subsequent owner, though some require formal registration within a set window after the sale. Contact Correll Roofing at (314) 222-9529 for details on your specific warranty documentation.

What should I do if I think I have a warranty claim?

Contact Correll Roofing first before attempting repairs yourself or hiring another contractor. Call (314) 222-9529 or use the contact form to describe the issue. We'll schedule an inspection, assess whether it is a workmanship, product, or insurance matter, and walk you through the appropriate next steps.

Why Warranty Matters

Two Layers of Protection on Every Roof We Install

A roof is one of the largest investments a homeowner makes. Understanding exactly what stands behind that investment — and who backs it — gives you real peace of mind long after the last shingle is nailed down.

Manufacturer Warranty

Material Coverage From the Source

Roofing manufacturers stand behind the products they produce. When Correll Roofing installs qualifying shingles, underlayment, and accessory products, the manufacturer's limited warranty travels with those materials for the life you and your family spend under that roof.

Product defects — manufacturing imperfections in shingles, underlayment, or accessories are covered.
Premature wear — shingles that deteriorate faster than their rated lifespan under normal conditions.
Algae and staining resistance — qualifying products carry specific stain-warranty coverage.
Wind speed ratings — many manufacturers warranty shingles against blow-off up to a rated wind speed when installed to spec.

Coverage terms vary by product line. When we review your project, we explain exactly which warranty tier applies to the materials selected for your home.

Material Integrity

Manufacturer warranties are tied to the product itself. As long as the shingles are installed correctly, that coverage is active from day one.

System Approach

Roofing systems work together — shingles, underlayment, ridge cap, flashing, ventilation. Products designed to work as a system often unlock the highest coverage tiers.

Long-Term Value

A properly warranted roof protects your home's resale value. Buyers and inspectors recognize the difference between a documented warranty and a handshake promise.

Our Promise

The Correll Workmanship Guarantee

Materials are only as reliable as the crew that puts them in place. That's why Correll Roofing Co. stands behind the quality of our own labor with a separate workmanship warranty on every project we complete.

What It Covers

If a problem with our installation causes a leak or performance issue — improper flashing, missed fastener patterns, inadequate sealing at penetrations — we come back and fix it. No runaround, no finger-pointing at the manufacturer.

Family-Run Accountability

As a local, family-run business serving Greater St. Louis and St. Charles County for 20+ years, our name is on every job. We don't subcontract our responsibility — if your roof was installed by Correll, it's warranted by Correll.

Clean Transfer

Selling your home? Ask us about warranty documentation. A transferable workmanship warranty is a genuine selling point that gives the next owner confidence in the roof over their head.

Proper Installation

Why How a Roof Is Installed Determines Whether the Warranty Holds

Here's something the fine print makes clear: almost every manufacturer warranty requires the product to be installed according to their published specifications. Cut corners on installation and you may void the very coverage you counted on.

Fastener placement — nails driven too high or too low outside the nailing strip shift the load onto shingles, causing blow-offs and voiding wind warranties.
Ventilation balance — inadequate attic ventilation traps heat and moisture, accelerating shingle aging in ways that are specifically excluded from most warranties.
Flashing at transitions — chimneys, skylights, valleys, and wall intersections are the most common leak points. Proper step and counter-flashing technique is non-negotiable.
Ice and water barrier — Missouri winters bring freeze-thaw cycles that drive ice dams. A correctly installed ice-and-water shield at eaves protects where standard underlayment can't.

Our crews follow manufacturer specs on every roof replacement because doing it right the first time is the only way to honor both layers of warranty coverage.

2Warranty Layers

St. Louis-area homeowners deal with some of the most demanding roofing conditions in the midwest — spring hailstorms that can drop golf-ball-sized ice, summer heat that pushes attic temperatures past 150°F, and winter freeze-thaw cycles that exploit every small gap in flashing or underlayment. A properly installed, fully warranted roofing system is your defense against all of it.

When you choose Correll Roofing Co., you're not just buying shingles. You're buying the expertise of a family-run company with over two decades of experience navigating warranty claims, reading manufacturer specs, and putting crews on rooftops who know the difference between good enough and genuinely right. That combination — quality products installed correctly by people who stand behind their work — is what gives you real peace of mind.

FAQ

Warranty Questions We Hear Most Often

Straight answers about manufacturer coverage, workmanship guarantees, and what to do when something goes wrong.

A manufacturer warranty is provided by the company that made the roofing materials — shingles, underlayment, or accessories. It covers defects in the product itself and typically runs for a defined period tied to the product line you select. A workmanship warranty is separate and comes directly from your roofing contractor. It covers the quality of the installation — the way those materials were applied. If a leak happens because a flashing joint was improperly sealed or nails were driven at the wrong angle, that's a workmanship issue, not a product defect. Correll Roofing Co. provides both, so you're covered on all fronts.

Yes. Manufacturer warranties contain specific conditions that must be met for coverage to remain valid. The most common causes of voiding include: improper installation (fasteners outside the nail zone, inadequate ventilation), mixing incompatible materials from different product lines, pressure washing or applying non-approved coatings to the shingles, and in some cases allowing satellite dishes or HVAC equipment to be improperly fastened through the roof surface. This is exactly why hiring an experienced, installation-spec-compliant contractor like Correll Roofing matters so much — we install to the standards that keep your warranty intact.

Storm and hail damage is generally considered an external cause, not a product defect, so it typically falls under your homeowner's insurance policy rather than the manufacturer warranty. That said, if a hail event exposes a pre-existing installation defect — or if the damage raises questions about whether your roof was properly installed to begin with — there can be overlap. Correll Roofing works directly with insurance companies on storm and hail claims, helping you document damage accurately and navigate the claims process. If you've recently had a storm, a free inspection is always the right first step.

Ask us at project close — we'll walk you through the transfer provisions specific to your warranty documentation. Many manufacturer warranties are also transferable to a subsequent owner, though some require formal registration of the transfer within a set window after the sale closes. Having clear warranty paperwork on hand is a genuine asset during a home sale; buyers and their inspectors appreciate documented proof of a quality roof installation. If you're preparing to list your home in the St. Louis or St. Charles County area and want your warranty documents in order, give us a call at (314) 222-9529.

Contact us first. Don't attempt repairs yourself or hire another contractor to fix the issue before reaching out — unauthorized repairs can complicate both workmanship and manufacturer warranty claims. Call (314) 222-9529 or use our contact form to describe what you're seeing. We'll schedule an inspection, assess whether the issue is a workmanship matter, a product matter, or a storm/insurance matter, and walk you through the appropriate next step. As a family business with over 20 years in the St. Louis area, we have every reason to make this right — our reputation depends on it.
