1. Types of Commercial Roofing Warranties
When purchasing a commercial roofing system, you may receive different types of warranties, each covering different aspects of your roof. It’s important to understand the differences between them so you know exactly what to expect if an issue arises.
A. Manufacturer Material Warranty
A manufacturer’s warranty covers defects in the roofing materials themselves. If the materials fail due to a manufacturing defect, the manufacturer will replace or repair them at no cost to you. This type of warranty typically lasts 10 to 40 years, depending on the roofing system and manufacturer.
What’s Covered?
Defects in the roofing material (e.g., faulty membranes, defective metal panels)
Premature deterioration due to faulty production
Breakdown of protective coatings within the warranty period
What’s Not Covered?
Improper installation
Damage from extreme weather, such as hurricanes or tornadoes
Punctures, tears, or impact damage from debris
Lack of proper maintenance
B. Workmanship Warranty (Contractor Warranty)
A workmanship warranty is provided by the roofing contractor, like Karma Construction Group, and covers issues related to installation errors. Even the best roofing materials can fail prematurely if installed incorrectly, which is why this warranty is essential.
What’s Covered?
Errors in installation that lead to roof failure
Improper flashing installation
Leaks due to workmanship defects
Fastening and adhesion issues
What’s Not Covered?
Normal wear and tear
Weather-related damages
Structural movement causing roofing failure
Repairs made by unauthorized contractors
C. Full System Warranty
A full system warranty provides the most comprehensive coverage, typically covering both materials and workmanship. This warranty often includes roofing accessories, such as flashings, adhesives, and insulation.
What’s Covered?
Both material defects and installation errors
Roofing system components like insulation and adhesives
Comprehensive protection, often up to 25 years
What’s Not Covered?
Damage from improper maintenance
Extreme weather-related damages
Modifications or additions made after installation without approval
D. Extended Manufacturer Warranty
Some manufacturers offer extended warranties that provide additional protection beyond the standard material warranty. These warranties often require regular inspections and maintenance to remain valid.
What’s Covered?
Additional coverage for material defects
Some include a limited labor warranty for repairs
Coverage can extend up to 50 years
What’s Not Covered?
Neglect or lack of regular maintenance
Unauthorized repairs or modifications
Excessive foot traffic damage
2. Common Exclusions in Commercial Roofing Warranties
Even the most comprehensive commercial roofing warranties come with limitations and exclusions. Understanding these exclusions helps you avoid costly surprises when an issue arises.
A. Extreme Weather Events

Most warranties exclude damage caused by severe storms, hurricanes, tornadoes, hail, and earthquakes. Raleigh is prone to heavy storms and high winds, so business owners should ensure their insurance policy covers weather-related roof damage.
B. Poor Maintenance
If a commercial roof is not properly maintained, the warranty may be voided. This includes:
Failure to remove debris from gutters and drains
Allowing ponding water to remain on the roof
Not addressing small leaks before they become major problems
C. Unauthorized Repairs
Many warranties require that any repairs or modifications be performed by an approved contractor, such as Karma Construction Group. Unauthorized repairs can void the warranty entirely.
D. Roof Modifications
Adding new HVAC units, solar panels, or satellite dishes to a commercial roof without manufacturer approval can result in warranty cancellation.
3. How to Keep Your Warranty Valid
A. Work with a Certified Contractor
Choosing an experienced, certified commercial roofing contractor like Karma Construction Group ensures that your roof is installed according to manufacturer guidelines, keeping your warranty intact.
B. Schedule Regular Inspections
Many warranties require annual or bi-annual inspections to remain valid. Regular inspections help identify minor issues before they become major problems.
C. Maintain Proper Documentation
Keep records of all:
Roof inspections
Maintenance and repair work
Communication with the roofing manufacturer
Warranty agreements and terms
D. Perform Routine Maintenance
To prevent warranty issues, schedule regular roof maintenance that includes:
Cleaning gutters and drains
Checking for and sealing minor cracks
Removing debris that could puncture roofing materials
