What You’ll Need Before You Start
Gather your original roofing contract, warranty certificates, maintenance records, and contractor contact information. If you inherited the property, request these documents from the previous owner or property manager. Keep digital copies in cloud storage as backup.
Your warranty documentation may include a comprehensive document or separate certificates for materials and workmanship. The manufacturer’s warranty typically arrives as a formal certificate with serial numbers tied to your specific installation. Most warranties require proof of proper installation, maintenance records, and evidence that the roof hasn’t been altered without authorization.
How to Check Commercial Roof Warranty Requirements
Checking your commercial roof warranty requirements is a methodical process that begins with careful document review. The goal is to understand exactly what your warranty covers, what it doesn’t, and what actions you must take to keep it valid.
Step 1: Locate Your Warranty Documentation
Find all warranty-related paperwork associated with your roof installation, including the manufacturer’s warranty certificate and contractor’s workmanship warranty. Check your files from installation time, or contact the roofing contractor who performed the work. Reputable companies like DGK Home Solutions maintain detailed records and can provide copies of warranty documentation.
For properties that have changed hands, verify that warranty documentation transferred as part of the sale. Some warranties transfer to new owners while others are specific to the original purchaser, this distinction matters significantly for your coverage.
Step 2: Identify Your Warranty Type
Commercial roof warranties come in distinct categories, each with different coverage levels and requirements.
Manufacturer’s Material Warranty covers defects in roofing materials and typically lasts 10 to 25 years depending on material type and quality. The manufacturer guarantees that materials won’t fail due to manufacturing defects under normal conditions.
Contractor’s Workmanship Warranty covers installation quality and typically lasts 1 to 10 years, protecting against installation errors like improper flashing or inadequate sealing. DGK Home Solutions provides workmanship warranties reflecting our commitment to quality installation.
Extended or Enhanced Warranties are optional coverage you can purchase to extend protection beyond standard warranties, including wind coverage, hail protection, or extended material warranties.
System Warranties cover the entire roofing system as a complete unit, common with modern commercial roofing systems and typically requiring that all components come from the same manufacturer or approved compatible products.
Step 3: Review Coverage Terms and Exclusions
Identify the coverage period, most manufacturer warranties list a primary coverage period of 10, 15, 20, or 25 years, often followed by a prorated period where coverage decreases over time. Examine what specific conditions void coverage, such as improper installation, lack of maintenance, unauthorized repairs, or alterations. Weather events like hurricanes may be excluded in certain regions.
Check whether the warranty covers labor costs or only materials. Some warranties cover replacement materials but not installation labor. Examine any conditions related to maintenance, many warranties require regular inspections to remain valid.

Step 4: Check Maintenance and Inspection Requirements
Warranty validity often depends on maintaining your roof according to specific schedules outlined in the warranty documentation. Review your warranty for inspection frequency requirements, many commercial roof warranties require inspections at least once or twice per year, and some specify inspections after severe weather events.
Check whether the warranty specifies who can perform maintenance. Some manufacturers require certified contractors or the original installer; others allow any qualified roofing professional. Look for requirements about debris removal, gutter cleaning, or drainage maintenance. Warranties often require that roofs remain free of standing water and that gutters function properly.
Keep detailed maintenance records with dates, descriptions of work performed, contractor names, and observations about roof condition. These records prove compliance with warranty requirements and provide essential documentation for claims. When working with professional roofing companies like DGK Home Solutions, request written documentation of all work performed.
Commercial Roof Maintenance Checklist to Preserve Coverage
Maintaining your commercial roof according to warranty requirements protects both your physical asset and your warranty coverage.
| Maintenance Task | Frequency | Documentation Needed |
|---|---|---|
| Visual roof inspection | Annually (or twice yearly) | Date, inspector name, findings, photos |
| Debris and leaf removal | As needed, typically spring/fall | Date, amount removed, contractor name |
| Gutter and downspout cleaning | Twice yearly or as needed | Date, cleaning completion confirmation |
| Standing water inspection | After heavy rain or annually | Visual confirmation, photos if pooling exists |
| Flashing and seal inspection | Annually | Condition assessment, any deterioration noted |
| HVAC/equipment inspection | Annually | Confirmation that penetrations remain sealed |
| Damage assessment after storms | Within 48 hours of event | Photos, descriptions, contractor evaluation |
| Caulk and sealant inspection | Annually | Condition notes, repair recommendations |
| Drain and downspout function test | Twice yearly | Confirmation of proper drainage |
| Contractor maintenance visit | Per warranty requirements | Service report, work performed details |
Establish a maintenance schedule and stick to it. Schedule inspections for spring and fall, before and after heavy weather seasons. Set calendar reminders to ensure inspections happen on schedule. Request detailed reports from professionals documenting what was inspected, found, and repaired.
What Voids a Commercial Roof Warranty
Understanding what actions or conditions void your warranty protection helps you avoid costly mistakes.
Lack of Maintenance is one of the most common warranty violations. If your warranty requires annual inspections and you haven’t had them performed, you may have voided coverage. Documentation of regular maintenance proves you’ve held up your end of the warranty agreement.
Unauthorized Repairs or Modifications void most warranties. Any work on the roof should be performed by qualified professionals who understand warranty requirements and can document that work properly.
Improper Installation voids manufacturer warranties. Working with experienced, reputable contractors like DGK Home Solutions ensures proper installation that protects your warranty from day one.
Foot Traffic and Unnecessary Roof Access can void warranties if the roof isn’t designed for regular foot traffic. Designate specific access paths if foot traffic is necessary.
Alterations to the Roof System without manufacturer approval void coverage. If modifications are necessary, contact the manufacturer or your contractor to understand how to proceed while maintaining warranty validity.
Failure to Transfer Warranty Properly can void coverage when property ownership changes. Some warranties are non-transferable; others transfer but require formal notification to the manufacturer.
Natural Disasters or Acts of God may be excluded from coverage depending on your warranty and location. Check your specific warranty language to understand regional exclusions.
Commercial Roof Inspection Requirements for Warranty Compliance
Regular inspections are the foundation of warranty compliance and the best way to catch problems before they become expensive repairs.
Annual Inspections are the standard requirement for most commercial roof warranties. Qualified roofing professionals should examine the entire roof surface for cracks, blistering, punctures, or membrane separation. They should inspect all flashing around penetrations, edges, and transitions, and verify that rooftop equipment remains properly sealed.
Post-Storm Inspections are often required within 48 hours of severe weather events. Documenting that you had the roof inspected after storms provides evidence of diligence if damage claims arise later.
Professional Certification matters for warranty compliance. Some warranties specify that inspections must be performed by certified roofing professionals or the original contractor. Verify your warranty requirements and ensure inspections are performed by qualified professionals.
Documentation Standards are crucial. Inspection reports should include the date, inspector name and credentials, detailed roof condition description, photographs of any damage or concerns, and repair recommendations. This documentation proves you’ve maintained the roof according to warranty requirements.
Establish a relationship with a qualified roofing contractor who can perform inspections consistently and maintain records over time. This continuity provides valuable perspective on roof condition trends.
Manufacturer’s Warranty vs. Contractor’s Workmanship Warranty
These two warranty types serve different purposes and have different coverage, duration, and requirements.
Manufacturer’s Warranty protects against defects in roofing materials and typically lasts 15 to 25 years. The manufacturer guarantees that materials will perform as designed. This warranty is usually tied to specific materials and may be non-transferable or have restrictions if property ownership changes.
Contractor’s Workmanship Warranty protects against installation errors and typically lasts 1 to 10 years. A workmanship warranty from DGK Home Solutions reflects our confidence in our installation quality and commitment to standing behind our work.
Key Differences in Coverage: The manufacturer’s warranty covers material defects like premature deterioration or manufacturing flaws. The contractor’s warranty covers installation errors like improper sealing or inadequate fastening. A leak caused by a manufacturing defect might be covered by the manufacturer’s warranty but not the contractor’s warranty.
Duration Differences: Manufacturer warranties typically extend much longer than workmanship warranties. A manufacturer might provide a 20-year material warranty while the contractor provides a 5-year workmanship warranty.
Transfer and Assignment: Some manufacturer warranties transfer to new owners with restrictions or reduced coverage. Workmanship warranties are typically specific to the original building owner and may not transfer.
Claim Procedures: Manufacturer claims require proof of material defect and may require manufacturer inspection. Contractor claims require proof that an installation error caused the problem. Both require documentation of proper maintenance and compliance with warranty requirements.
Having both warranties provides comprehensive protection, materials are covered by the manufacturer and installation quality is covered by the contractor.
Common Mistakes to Avoid When Managing Your Warranty
Neglecting to Keep Maintenance Records is perhaps the most damaging mistake. Without documented proof of maintenance compliance, you cannot prove compliance if a claim is disputed. Keep every inspection report, maintenance invoice, and service record.
Failing to Schedule Regular Inspections leaves you vulnerable to warranty violations and misses opportunities to catch small problems before they become expensive repairs.
Attempting DIY Repairs can void warranty coverage. Any roof work should be performed by qualified professionals who understand warranty requirements and can document their work properly.
Installing Equipment Without Proper Authorization creates roof penetrations that may violate warranty terms. Work with your roofing contractor to ensure proper installation and sealing.
Allowing Standing Water to Accumulate violates most warranty terms. Contact your roofing contractor immediately if you notice standing water after rain.
Transferring Properties Without Verifying Warranty Status can leave you without coverage you thought you had. Request all warranty documentation and verify what coverage transfers to you as the new owner.
Hiring Unqualified Contractors creates documentation problems and may violate warranty terms. Always verify that contractors are qualified and can provide proper documentation.
Ignoring Warranty Exclusions leads to denied claims. Read your warranty carefully to understand what isn’t covered.
Delaying Repairs After Storm Damage can complicate warranty claims. Document damage immediately with photographs and have a professional inspection performed within 48 hours.
Not Communicating with Your Contractor about warranty requirements means they may not understand what documentation you need. Clear communication ensures everyone understands what’s required.
Managing your commercial roof warranty effectively requires understanding what coverage you have, meeting maintenance requirements, and keeping detailed documentation.

Frequently Asked Questions
What voids a commercial roof warranty?
A commercial roof warranty becomes void when maintenance requirements are neglected, unauthorized repairs are performed, or the roof is damaged from improper installation. Missing required inspections, failing to address minor issues promptly, and using non-approved roofing materials can also void coverage. Always verify what specific actions your warranty prohibits before making any repairs or modifications to your roof.
How often should I inspect my commercial roof to keep the warranty valid?
Most commercial roof warranties require inspections twice per year, typically in spring and fall, to catch damage early and document the roof’s condition. Some manufacturers mandate annual professional inspections by a certified inspector. Check your warranty documentation for the exact frequency required, as failing to meet inspection schedules is a common reason coverage is denied when you need it most.
What is the difference between a manufacturer’s warranty and a contractor’s workmanship warranty?
A manufacturer’s warranty covers defects in the roofing materials themselves, such as shingles or membranes failing prematurely. A contractor’s workmanship warranty covers the quality of installation, ensuring seams are sealed properly, fasteners are correct, and the roof is installed to code. Both are important: material defects and poor installation both cause leaks. Review both warranties to understand your complete coverage.
How do I find my commercial roof warranty documentation?
Check your building’s original construction or renovation records, contact the roofing contractor who installed the roof, or request documents from your property manager or previous owner. Manufacturers and contractors often keep warranty records on file. If you cannot locate the original paperwork, contact the roofing company directly with your roof installation date and building address, they can issue a replacement copy or confirm warranty details.
