Is It Time For Your Business To Get A New Roof?
Waiting too long to replace your business’s failing roof can lead to costly damage and unexpected disruptions. If you notice that your commercial roof is showing signs of wear or isn’t performing as it should, it may be time to act. At Vanguard, we help building owners and managers make informed decisions by identifying warning signs early.
- Leaks that keep coming back, even after multiple repairs
- Visible ponding water that doesn’t drain within 48 hours after rainfall
- Blisters, cracks, or open seams in the roof membrane
- Sagging roof areas or soft spots underfoot
- Peeling flashing or loose rooftop equipment connections
- Water stains or mold inside the building
- Rising energy costs caused by poor insulation or roofing performance
- Roof age exceeding 20 years (or sooner for lower-grade systems)
- Damage from rooftop traffic or improper repairs
- Plans to install solar or rooftop equipment, which require a stable foundation
If you see one or more of these issues, Vanguard can assess your roof and recommend the best next steps—whether that’s a targeted repair, retrofit, or full replacement.
