When you are getting quotes for a new roof, every contractor mentions a warranty. But not all roofing warranties are the same. Some cover only materials. Some cover labor. Some sound comprehensive until you read the fine print and find that most real-world scenarios are excluded. Understanding your roofing warranty before you sign is one of the most important steps in any roof replacement, and it is a question homeowners ask us regularly whether they are looking at roofing contractors in Norwood, MA or anywhere else in Massachusetts or Rhode Island..
This guide explains exactly how roofing warranties work in Massachusetts so you can ask the right questions and make sure the coverage you are promised is the coverage you actually receive.
The Two Types of Roofing Warranties
Every roofing warranty falls into one of two categories, and a complete roofing job should include both.
Manufacturer’s warranty. Provided by the company that made the shingles or roofing materials. It covers defects in the product itself. If a shingle fails due to a manufacturing flaw, this is the coverage that protects you.
Workmanship warranty. Provided by the roofing contractor. It covers problems caused by how the roof was installed. If a leak develops because of improper flashing, inadequate ice and water shield coverage, or a fastening error, the workmanship warranty is what should protect you.
Both matter. Having only one type leaves you exposed on the other side.
What a Manufacturer’s Warranty Actually Covers
Manufacturer warranties vary significantly by product line and by the certification level of the contractor who installs the product. The most important things to understand are the term length, whether the warranty is prorated, and the transferability terms.
Term length. A 30-year limited warranty does not mean the manufacturer will replace your entire roof for 30 years. The term describes how long coverage exists, but many warranties reduce in value over time.
Proration. A prorated roofing warranty means the amount the manufacturer will pay on a claim decreases as the roof ages. When you are weighing roof replacement cost against the value of your warranty coverage, proration matters enormously. A shingle that fails in year 25 of a 30-year prorated warranty may only be covered at a fraction of the actual replacement cost. Non-prorated warranties maintain full coverage throughout the term, which represents a meaningfully better return on your roof replacement cost.
Transferability. CertainTeed’s highest-tier warranties are transferable within the first 15 years, which adds real resale value to your home.

What a Workmanship Warranty Covers
A workmanship warranty covers installation errors, including improper flashing around chimneys, skylights, and vents, inadequate ventilation that causes moisture buildup in the attic, insufficient ice and water shield coverage along eaves and valleys, and fastening errors that allow shingles to lift in a storm.
Workmanship warranty terms vary widely by contractor. Before you hire a roofing contractor in Massachusetts, ask directly about the workmanship warranty term and get it in writing as a separate document from the manufacturer warranty.
The quality of a workmanship warranty is only as good as the contractor behind it. A contractor who goes out of business after the job cannot honor a warranty, regardless of what the paperwork says. Choosing an established, licensed, insured contractor with a long track record in Massachusetts is how you make sure the coverage you receive is actually worth something.
What Can Void Your Roofing Warranty
Improper installation. If the roof is not installed to the manufacturer’s specifications, many product warranties are void. This is why installer certification matters so much.
Unauthorized repairs. Work performed by a non-certified contractor after installation may void the warranty.
Failure to register. Some warranty tiers require registration within a set window after installation. Confirm your contractor handles this on your behalf before work begins.
Excluded events. Most warranties exclude Acts of God. Your homeowner’s insurance typically covers storm-related damage. The Massachusetts Office of Consumer Affairs and Business Regulation provides guidance on contractor licensing and your consumer protection rights if questions arise after a project is complete.
Why Your Contractor’s Certification Tier Determines Your Coverage
The roofing warranty tier available to you from a manufacturer like CertainTeed is determined by the certification level of the contractor who installs your roof, not just the product you choose.
CertainTeed’s certification program has three tiers: Master, Select, and Premier. Only a Premier certified contractor can offer the SureStart PLUS roofing warranty, the strongest coverage CertainTeed provides. That means two homeowners can have the exact same CertainTeed shingles installed and end up with completely different protection, simply because one chose a Premier certified contractor and the other did not.
This distinction directly affects the value you get from your roof replacement cost. The same dollars spent on materials can yield dramatically different warranty coverage depending entirely on who installs them. The National Roofing Contractors Association notes that contractor qualifications directly affect both installation quality and the warranty coverage homeowners receive.
What the CertainTeed SureStart PLUS Warranty Includes
The SureStart PLUS roofing warranty, available only through a CertainTeed Premier certified installer like Marios, is the most comprehensive coverage CertainTeed offers.
Non-prorated coverage. Full replacement value throughout the warranty term, not a declining percentage as the roof ages.
Labor and materials. Both the cost of replacement shingles and the labor to install them are covered, not just the product.
Tear-off and disposal. If a claim requires removing the existing roof, those costs are included.
Transferability. The warranty transfers to a new homeowner within the first 15 years, adding real resale value if you ever sell.
Marios is the first and only roofing contractor in Massachusetts and Rhode Island to hold the CertainTeed ShingleMaster Premier certification. Every homeowner we work with gets access to this coverage. Read more about what our certification requires on our industry certifications page.
What to Ask Before You Sign
Before you agree to any roofing contract in Massachusetts, get clear answers to these questions in writing.
What manufacturer roofing warranty tier comes with this installation, and is it prorated? Ask specifically whether it covers labor as well as materials.
What workmanship warranty do you provide, and how long does it last? This should be a separate document from the manufacturer warranty.
What is your CertainTeed certification level? If you are currently evaluating roofing contractors, this is the single most important differentiator to ask about. A contractor who cannot name their certification tier is giving you an answer whether they mean to or not. Marios is a CertainTeed Premier ShingleMaster, which is only given to the top 1% of roofing professionals nationwide. This gives our customers access to exclusive warranties and superior materials.
Will you register the warranty on my behalf after completion? Confirm this before work starts.
