Having the right insurance policy can work wonders in times of disaster. But are you optimizing your premiums and reducing costs by taking everything into account?

Every Roofing Factor That Affects Your Commercial Insurance Costs, Frequency, and Scope of Replacement

1. Life Cycle Roof ManagementFor the Midwest, this includes:
  • Annual inspections
  • Drain cleaning
  • Snow removal
  • Ice dam removal
  • Heat tape installation
Maintenance records can help reduce your insurance premiums.
2. No Proactive Maintenance

According to data gathered in a 15-year alliance between Elevate Building Products and ProLogis, proactively maintaining a roof leads to significant savings.

Proactive Maintenance ~$0.14/sq ft annual cost Reactive Maintenance ~$0.25/sq ft annual cost
That’s a savings of $0.11/sq ft per year with a proactive approach.
3. Damage From Other Trades~40% of all roof problems occur because of human error due to uncertified installs and maintenance, such as:
Plumbing HVAC Solar Facility Maintenance

With all this in mind, what options do you have for lowering roofing project costs?

The other hidden cost driver? A better commercial roofing warranty.

Getting a Good Warranty to Go With Your Roof

A good roof warranty can:
  • Protect against expensive damages
  • Last 20+ years
  • Increase the value and marketability of a facility
But not all warranties are built alike — here’s how to know you’re getting a good deal.

Two Types of Warranty

Manufacturing Warranty

The manufacturer repairs or replaces compromised materials. Two general categories:

  • Standard Material: Manufacturing defects
  • Extended System: Complete coverage
 Workmanship Warranty

The installer repairs or replaces damage.
KRI is certified to provide 20–40 year warranties depending on the roofing system. Not all contractors can provide these warranties due to the certification required.
Avoid: Defect-Only Warranties

How to avoid voiding roof warranties:

  • Improper installation by other trades
  • Uncertified service
  • Poor maintenance and maintenance records
  • DIY work or modifications
  • Inadequate ventilation
 Opt For
  • Dual manufacturer and workmanship warranties
  • Longer warranties from long-lasting, proven providers
  • Warranties that address weather in the Midwest

Avoid all these issues (and more) by hiring a trusted roofing contractor like Kato Roofing — an award-winning, woman-owned roofing contractor serving Minnesota and the upper Midwest. All complete roofing systems come with a standard KRI warranty, plus an optional manufacturer’s warranty.
