Planning a Fit-Out or Tenant Build-Out? Don’t Overlook the Roof.
For property managers and pre-construction teams, tenant improvement projects bring a mix of excitement and pressure. Whether you’re accommodating new lease agreements, enhancing functionality, or reconfiguring interior layouts, these projects often focus heavily on interiors. But one key element that’s too often overlooked: the roof.
Before walls go up and interiors get built out, it’s critical to involve your roofing contractor early in the conversation. Below are five questions you should ask before any fit-out or tenant build-out begins:
1. Is the current roofing system compatible with the proposed interior improvements?
Adding new HVAC units, venting, or skylights? These upgrades might require roof penetrations or changes to the membrane system. Your contractor should evaluate the existing roof system to ensure it can support modifications without voiding warranties or compromising performance.
2. Are there any existing roof issues that should be addressed before the fit-out begins?
There’s no sense in building out interiors beneath a compromised roof. A thorough inspection can uncover compromised insulation, deteriorated flashing, or poor drainage. Fixing these upfront can save your team major headaches (and tenant complaints) down the line.
3. What’s the best way to handle rooftop mechanical coordination?
Tenant improvements often involve reconfigured mechanicals. Your roofing contractor should work closely with mechanical trades to seal curbs properly, flash new units correctly, and preserve watertight integrity. Coordination here is key to avoiding future leaks and disputes.
4. How will this work affect existing warranties?
Any rooftop modifications can potentially void existing warranties, especially manufacturer coverage. A qualified commercial roofer like CP Rankin will evaluate your current warranty, coordinate with manufacturers if needed, and propose solutions that preserve or extend coverage.
5. Can you provide documentation for permitting or final close-out packages?
Most municipalities require documentation for mechanical or structural changes during tenant improvements. Your roofer should be able to provide as-built photos, scope summaries, or certifications as needed for permitting or turnover.
