What to Expect During a Commercial Roof Replacement

A commercial roof replacement is a significant undertaking, but with the right knowledge and team, it doesn’t have to be overwhelming. Whether your building is experiencing leaks, has reached the end of its service life, or is no longer up to code, replacing the roof is a critical step in protecting your investment and ensuring the safety of tenants and assets. At Keystone Engineering, we help streamline the process every step of the way through our specialized Roofing Division-dedicated to evaluating, overseeing, and supporting successful commercial roofing projects across Florida’s East Coast.

Here’s what to expect during the process, from initial assessment to final inspection:

1. Initial Assessment & Planning

Every successful roof replacement begins with a comprehensive assessment. Keystone Engineering’s Roofing Division performs detailed inspections to evaluate the current condition of your roof and identify signs of water intrusion, structural deficiencies, or code non-compliance.

What you can expect:

  • On-site visual inspection
  • Recommendations aligned with Florida Building Code and manufacturer specifications
  • Detailed recommended project scopes, cost estimates, and timelines
2. Specifications and Bidding

Keystone prepares our Project Manual which includes bid documents, scope of work, and specifications that support our Sealed Bidding Process and satisfies all building code requirements.

Our Roofing Project Managers conduct a meeting with well-vetted contractors on-site to answer any questions each bidder may have and allow them to take measurements to aid in bidding.
Our bid documents are used by each bidder to ensure each bid received is in a consistent, easy to understand format, allowing for a simple comparison of bids

3. Permitting & Scheduling

Permits must be secured before any work begins. Well-vetted contractors handle permitting efficiently, while scheduling is planned to minimize disruption.

What you can expect:

  • Permitting managed by your selected contractor
  • Clear project timelines and communication with tenants/staff
  • Mobilization of materials and heavy equipment
4. Tear-Off and Preparation

The old roofing system is removed in phases to ensure safety and reduce risk. Our team ensures your chosen contractor uses all appropriate protective measures for the interior and exterior of the building.

What you can expect:

  • Some noise and limited access to work zones
  • Protective coverings over windows, doors, and landscaping (if needed)
  • Cranes, dumpsters, and work crews on-site
5. Installation of New Roof System

With the surface prepped, installation of the new system begins. Whether it’s TPO, modified bitumen, or metal, our Roofing Division oversees quality control at every milestone to ensure long-term performance and durability.

What you can expect:

  • Installation of insulation, vapor barriers, membranes, and final surfacing
  • Coordination with contractors and local inspectors
  • Regular progress reports and on-site inspections from Keystone
6. Final Inspection and Cleanup

Once complete, a final inspection confirms that all specifications and codes have been met. Keystone provides a comprehensive closeout report, ensures the site is restored, and warranty documentation is issued by the contractor.

What you can expect:

  • Walkthroughs with project managers and contractors
  • Completion of punch list items
  • Return to full building access and a clean site
Minimizing Disruptions

At Keystone Engineering, we understand that minimizing disruptions to your tenants and business is essential. Our Roofing Division collaborates with property managers and boards to schedule noisy or high-impact work outside of peak business hours, ensure clear communication, and uphold safety protocols throughout the project.
