We’re Owens Corning Platinum! More peace of mind. Stronger warranty options on eligible Owens Corning roofing systems. 

When you invest in a new roof, you're not just buying shingles — you're buying decades of protection for everything underneath them. That's why one of the most important questions any Indiana homeowner can ask a roofer is a simple one: "What happens if something goes wrong?"

At Porter Roofing & Restoration, our answer is the Porter Promise — a lifetime workmanship warranty that stands behind the way we install your roof. It's a big commitment, and we make it on purpose. Here's what a workmanship warranty actually covers, how it's different from the material warranty that comes with your shingles, and why "get it right once" is at the heart of how we work.

Quick Answer

A material warranty covers defects in the shingles and roofing products themselves and comes from the manufacturer. A workmanship warranty covers the quality of the installation — the labor and craftsmanship our team provides. Porter's lifetime workmanship warranty, the Porter Promise, means we stand behind how your roof is installed for the life of your ownership, giving you one clear point of accountability and real peace of mind.

Material Warranty vs. Workmanship Warranty: What's the Difference?

Most homeowners assume a roof comes with "a warranty" — one single blanket of coverage. In reality, there are two distinct protections at work, and understanding the difference helps you know exactly who stands behind what.

The material warranty (from the manufacturer)

A material warranty is issued by the company that makes your roofing products. It covers manufacturing defects — problems with the shingles or components themselves, such as premature granule loss or a product that fails to perform as designed. If the material is flawed, the manufacturer's warranty is what addresses it.

Because Porter is an Owens Corning Platinum Preferred contractor — the manufacturer's top certification tier — the homeowners we serve have access to some of the strongest material warranty options Owens Corning offers. The specific coverage depends on the products and warranty package selected for your project, and we'll walk you through the exact terms before any work begins.

The workmanship warranty (from your roofer)

A workmanship warranty is different. It has nothing to do with the shingles and everything to do with how the roof was installed. Even a perfect product can leak or fail early if it's put on incorrectly — flashing done wrong, nails placed poorly, or details around valleys, vents, and chimneys rushed.

The workmanship warranty is the roofer's promise that the installation itself was done right. The Porter Promise is our lifetime workmanship warranty, and it reflects our confidence in the crews who do the work.

Why "Get It Right Once" Matters

You've probably heard the phrase "measure twice, cut once." Roofing works the same way — except the stakes are your home and everything in it.

When a roof is installed correctly the first time, you get:

  • Fewer callbacks and repairs over the life of the roof
  • Better long-term performance from the materials you paid for
  • Cleaner protection for your attic, insulation, and interior
  • Real peace of mind instead of a nagging worry about the next storm

A workmanship warranty is only as good as the work behind it. That's why the Porter Promise isn't a marketing line — it's an accountability standard we hold ourselves to on every job. Our approach is simple: fast response, clean install, no surprises. Getting it right once means you're not the one left chasing down problems later.

What a Workmanship Warranty Gives Indiana Homeowners

Indiana weather doesn't take it easy on roofs. Between summer storms, freeze-thaw cycles, and heavy winter loads, your roof works hard year-round. A strong workmanship warranty matters here for a few practical reasons.

One clear point of accountability

When your installation is backed by a lifetime workmanship warranty from a local company, you know exactly who to call. There's no finger-pointing between the manufacturer and the installer — the Porter Promise means we stand behind our own work.

Confidence that details were done right

Most roof leaks don't start in the middle of a shingle field. They start at the transitions — flashing, valleys, penetrations, and edges. These are the areas where craftsmanship shows. A workmanship warranty signals that a roofer is confident those critical details were handled correctly.

Protection that follows your ownership

The Porter Promise is designed to give you long-term peace of mind for as long as you own your home. Because warranty terms and any transfer conditions can vary by project, we'll review the specifics with you in plain language so you know exactly what's covered. 

How Porter Backs the Promise

A warranty is a document, but peace of mind comes from the process behind it. Here's how we work to make sure the Porter Promise holds up:

  • Trained, accountable crews. Our installation standards are built around doing the details right, not just fast.
  • Platinum-level standards. As Indiana's Owens Corning Platinum Preferred team, we're held to the manufacturer's highest certification requirements.
  • A clean-jobsite standard. We treat your property with respect from the first day to the final nail sweep.
  • Responsive service. During business hours, we aim to respond in under 10 minutes — so if you ever have a question, you're not left waiting.

Frequently Asked Questions

What's the difference between a lifetime workmanship warranty and a material warranty? The material warranty comes from the manufacturer and covers defects in the roofing products themselves. The workmanship warranty comes from your roofer and covers the quality of the installation. The Porter Promise is our lifetime workmanship warranty, standing behind how your roof is installed.

Does the Porter Promise cover storm damage? A workmanship warranty covers installation quality, not damage caused by severe weather, so storm damage is typically handled separately — often through a homeowner's insurance process. If you think a storm has affected your roof, the best first step is to book a complimentary inspection so we can document what we find. We can't promise any insurance outcome, but we can help you understand the condition of your roof.

Is the workmanship warranty transferable if I sell my home? Transfer terms can vary depending on your specific warranty package. We'll go over the exact details with you before your project begins so there are no surprises. 

Do I need to do anything to keep my warranty valid? Routine roof care and maintenance help protect your investment. We're happy to walk you through simple upkeep steps, and our team is a quick call away if you ever have a concern.

Peace of Mind Starts With Getting It Right

A lifetime workmanship warranty isn't just a perk — it's a reflection of how a roofer approaches the work. The Porter Promise exists because we believe in doing your roof right the first time and standing behind it for the long haul. That's what "Built on Trust" means to us.

If you're planning a roof replacement or just want to know where your current roof stands, we'd love to help.
