4 Types of Commercial Roofing Warranties

Ways to Protect Your Investment

Commercial roofing warranties fall into three main categories based on what they cover and who provides them. Understanding these categories helps property owners evaluate options and select appropriate coverage levels.

County Roofing Systems has over 35 years of experience protecting commercial properties throughout Long Island and Westchester County. We’re not a national franchise that treats every building the same. We’re local roofing contractors who understand how to maximize warranty protection for property owners in our region.

Material-Only Manufacturer Warranties

Material-only warranties cover defects in roofing products themselves. If membranes develop premature cracks, fasteners corrode, or insulation degrades due to manufacturing flaws, the manufacturer replaces those materials at no charge.

Most manufacturers include material-only warranties free with their products. These standard warranties typically last 10-20 years depending on the roofing system. Premium materials may include longer warranty periods.

Material-only warranties don’t cover labor costs for repairs. If a membrane fails under warranty, the manufacturer provides replacement membrane but property owners pay for removal, disposal, and reinstallation. Labor typically costs more than materials for commercial roofing repairs.

Property owners spend thousands removing and reinstalling roofing systems even when materials are free. A 5,000 square foot membrane replacement might cost $15,000-25,000 in labor despite free materials. This significant limitation reduces material-only warranty value.

Material-only warranties exclude installation-related problems. If leaks result from improper flashing installation or inadequate seam welding, material warranties don’t apply. Only defective products are covered, not workmanship issues.

Material and Labor Warranties

Material and labor warranties cover both defective products and the cost of removing and reinstalling them. These warranties provide substantially better protection than material-only coverage.

Coverage under material and labor warranties is typically prorated. Full coverage applies during early warranty years, then declines over time. A 20-year warranty might provide 100% coverage for years 1-5, 75% for years 6-10, 50% for years 11-15, and 25% for years 16-20.

Prorated coverage means property owners pay increasing percentages as roofs age. A warranty claim in year 15 provides 50% coverage, leaving the owner responsible for the other 50% of repair costs. This sharing reduces warranty value compared to non-prorated alternatives.

Material and labor warranties still exclude many common problems. Damage from storms, improper maintenance, unauthorized modifications, and normal wear typically aren’t covered. Property owners remain responsible for these repairs regardless of warranty status.

Costs for material and labor warranties vary but typically add $0.30-1.00 per square foot to installation costs. For a 20,000 square foot roof, that’s $6,000-20,000 in additional upfront expense. Whether this cost provides good value depends on the specific warranty terms and building situation.

NDL (No Dollar Limit) System Warranties

NDL warranties represent the most comprehensive coverage available for commercial roofing.

An NDL (No Dollar Limit) warranty is a type of manufacturer’s warranty and can also be offered as a single source warranty, where all materials are supplied and jointly warranted by a single manufacturer. These premium warranties cover the entire roofing system—membranes, insulation, fasteners, flashings, and all components—for the full warranty term without dollar limits or proration.

NDL coverage extends to all roofing system components and typically lasts between 10 and 30 years, with 20 years being the most common duration. Unlike material-only or material and labor warranties that cover just membranes, NDL warranties include insulation, cover boards, fasteners, flashings, and detail work. Complete system coverage eliminates gaps that leave property owners responsible for expensive repairs.

Labor costs are covered 100% throughout the warranty period. There’s no proration reducing coverage over time. Year 1 and year 20 receive identical coverage levels. This non-prorated protection provides substantial value over long warranty terms.

Exclusions in an NDL warranty can include acts of nature, improper maintenance, and modifications by unauthorized contractors.

NDL warranties typically cost $0.50-1.50 per square foot depending on warranty length and building characteristics. A 20-year NDL warranty on a 20,000 square foot building costs $10,000-30,000. While expensive, this warranty covers all materials, labor, and installation defects, and can save property owners hundreds of thousands in future repair costs.

Workmanship Warranties from Contractors

Separate from manufacturer warranties, roofing contractors provide workmanship warranties guaranteeing proper installation. These warranties protect against leaks and failures caused by installation errors rather than product defects.

County Roofing Systems provides workmanship warranties on all commercial installations. Our warranties complement manufacturer coverage by addressing installation-related issues. If seam failures, flashing problems, or other workmanship defects occur, we repair them at no charge.

Workmanship warranty lengths vary by contractor but typically range from 2-10 years. County Roofing Systems offers extended workmanship warranties that align with manufacturer coverage periods. This ensures property owners have complete protection throughout their roof’s early years.

0% Financing, Quick and Easy Approval

With nearly four decades serving homeowners under our belt, we know what’s needed to make your roofing project a success.

When you work with County Roofing, you get only the best. As little as 0% interest on approval for 5 years, quick approval, easy pay, and all backed by the best guarantees in the industry.

Warranty Coverage Details and Exclusions

All warranties include specific terms, conditions, and exclusions that property owners must understand. Reading warranty documents carefully prevents surprises when problems occur.

County Roofing Systems reviews warranty terms with property owners before installations begin. We explain what’s covered and what’s not.

What Warranties Typically Cover

When installing a new roof, it’s important to understand what the warranty covers.

Most commercial roof warranties specify coverage for materials, edge metals, membrane, fasteners, drainage components, and accessories, but the exact scope depends on the manufacturer’s warranty details. A manufacturer’s warranty typically provides more comprehensive coverage than a contractor’s warranty, often including both materials and labor for installation defects, and specifying the duration and conditions for validity.

Manufacturing defects in roofing materials are the primary coverage under all warranty types. If products fail to perform as specified due to manufacturing flaws, replacement is covered according to warranty terms. A thorough inspection by a manufacturer-trained inspector can help ensure that the roof was installed correctly, minimizing future warranty claims.

For NDL warranties, coverage extends to complete roofing system failures from any covered cause. This includes material defects, installation errors (if installed by certified contractors), and premature failures from normal wear within warranty specifications.

Weather-related damage may be covered under NDL warranties if failures result from manufacturing defects or installation problems. Standard weather damage from events like hurricanes typically requires insurance claims.

But warranty coverage applies if the roof shouldn’t have failed under those conditions. This distinction matters when evaluating claims.

Common Warranty Exclusions

Unauthorized modifications void most warranties. Adding new HVAC equipment, solar panels, or other rooftop installations without manufacturer approval typically cancels warranty coverage.

Property owners must obtain written approval before making any roof modifications. We help coordinate these approvals when needed.

Lack of maintenance is the most common reason for warranty denial. All manufacturers require regular roof inspections and completion of recommended repairs.

Documenting these maintenance activities is essential for maintaining valid coverage. Our maintenance programs satisfy these requirements.

Some warranties exclude high-wind damage above specified speeds. Roofs warranted for 90 mph winds won’t be covered for damage during 110 mph hurricanes.

Property owners in coastal areas should verify wind speed coverage matches actual exposure risks. Long Island properties need adequate wind coverage.

Ponding water often voids warranties. Standing water remaining on roofs more than 48 hours after rainfall indicates inadequate drainage.

Manufacturers exclude damage from ponding water, making proper drainage design critical during installation. We design drainage systems that prevent ponding.

Warranties don’t cover damage from foot traffic, vehicle access, or other unusual uses. Commercial roofs are designed for occasional maintenance access, not regular foot traffic or material storage.

Damage from improper use isn’t covered. Property owners must protect their roofs from abuse.

Warranty Costs and Return on Investment

Breaking Down the Numbers

Deciding whether premium warranties justify their costs requires analyzing potential repair expenses, building ownership plans, and risk tolerance. It’s important to note that as your roof ages, prorated warranties provide less coverage, meaning the protection decreases over time.

Prorated warranties decrease in value as the roof ages, while non-prorated warranties maintain full coverage for the duration.

County Roofing Systems helps property owners evaluate warranty options objectively. We present facts so you can make informed decisions.

Calculating Warranty Value

Consider a 20,000 square foot TPO roof with 20-year NDL warranty costing $20,000 extra. Over 20 years, that’s $1,000 annually for complete coverage.

If major repairs averaging $30,000-50,000 occur during that period, the warranty provides excellent value. One significant failure pays for the warranty investment.

Without warranty coverage, property owners risk substantial unexpected expenses. A membrane failure requiring partial roof replacement might cost $40,000-60,000.

Multiple smaller repairs over 20 years could exceed warranty costs even if no major failures occur. The math often favors premium warranties.

NDL warranties transfer to new owners. This enhances property values and makes buildings more attractive to buyers.

A commercial property with 15 years remaining on NDL warranty coverage is more valuable than identical property without coverage. Buyers recognize this protection.

Warranty peace of mind has value beyond pure financial calculations. Property owners budget with confidence knowing major roofing expenses are covered.

This predictability helps with financial planning and reduces unexpected capital expenditure risks. CFOs appreciate predictable costs.

Comparing Warranty Options

For buildings owners plan to hold long-term (15+ years), NDL warranties typically provide the best value. The comprehensive coverage and lack of proration protect against expensive problems throughout ownership.

Material and labor warranties work for shorter ownership periods (5-10 years) where full NDL protection exceeds likely benefits. These mid-tier warranties provide better protection than material-only coverage at lower costs than NDL options.

Material-only warranties are rarely the best choice for valuable commercial buildings. The exclusion of labor costs leaves property owners exposed to expenses often exceeding warranty upgrade costs.

Paying for better coverage upfront almost always makes financial sense. Saving $10,000 on warranties risks paying $50,000 for repairs.

Building use and roof accessibility affect warranty value. Facilities requiring frequent rooftop access face higher failure risks from foot traffic damage.

Premium warranty coverage provides more value when failure risks are elevated. High-risk buildings need better protection.

Maintaining Valid Warranty Coverage

How to Ensure You Remain Covered After Installation

Obtaining warranty coverage is just the first step. Maintaining valid coverage throughout the warranty period requires ongoing compliance with manufacturer requirements.

County Roofing Systems helps property owners meet these requirements. We make warranty maintenance simple and systematic.

Annual Inspection Requirements

Virtually all commercial roofing warranties require annual professional inspections. These inspections must be conducted by qualified roofing contractors who document roof condition and identify any necessary repairs.

County Roofing Systems provides annual inspection services that satisfy warranty requirements. Our technicians examine membranes, flashings, drainage systems, and all roofing components.

We document findings with photos and written reports submitted to manufacturers. You get complete documentation without administrative hassles.

Skipping required inspections voids warranty coverage. Manufacturers require proof that roofs have been properly maintained.

Missing even a single annual inspection can invalidate coverage, leaving property owners responsible for all repair costs. Don’t risk losing protection over inspection negligence.

Inspection costs typically range from $500-1,500 depending on building size and roof complexity. This annual expense is small compared to warranty value, making inspections an obvious investment for protecting coverage.

Completing Recommended Repairs

When inspections identify problems, manufacturers require timely completion of recommended repairs. Minor membrane damage, loose flashings, or drainage issues must be addressed to keep warranties valid.

Manufacturers typically require repairs within 30-90 days of discovery. Documentation proving repairs were completed must be maintained in property owner files.

This documentation may be requested if warranty claims are filed later. Organized records prevent claim denials.

Delaying recommended repairs can void coverage. If small problems identified during inspections are ignored and later cause major failures, warranty claims may be denied.

Manufacturers argue that proper maintenance would have prevented the failures. They’re usually right about this.

Our maintenance programs include both inspections and completion of minor repairs identified during visits. This comprehensive approach ensures warranty requirements are met while preventing small problems from becoming major issues.

Modification Approval Process

Property owners often need to modify roofs during warranty periods. New HVAC equipment, solar panel installations, or telecommunications equipment all require roof penetrations.

These modifications must be approved by warranty providers. Unauthorized changes void coverage immediately.

We help property owners obtain necessary approvals before modifications occur. We submit detailed plans showing how penetrations will be flashed and sealed.

Manufacturer representatives review plans and either approve them or suggest modifications. This approval process protects warranty coverage.

Unapproved modifications immediately void warranty coverage. This applies to the entire roof, not just modified areas.

A single unauthorized penetration for a new HVAC unit can eliminate coverage across 20,000 square feet of roofing. The consequences are severe.

Some modifications can’t be approved under existing warranties. Adding heavy equipment that exceeds roof load ratings or making changes that compromise drainage won’t receive approval.

In these cases, property owners must choose between modifications and maintaining warranty coverage. We help you understand these tradeoffs.

Working with a Certified Roofing Contractor: Experience the County Roofing Difference

Only certified roofing contractors can offer premium warranty options. Manufacturer certifications require contractors to meet strict standards for installation quality, business practices, and customer service.

County Roofing Systems maintains elite certifications from all major commercial roofing manufacturers. These certifications undergo annual renewal requiring proof of continued quality performance.

But working with a certified roofing contractor isn’t enough to guarantee a smooth roofing project.

At County Roofing, our manufacturer relationships help when warranty issues arise. We know who to contact at each company and how to navigate their claims processes.
