When It’s Time to Replace Your Flat Roof
Even the best repair crews can’t fight time forever. At some point, continuing to repair an old flat roof costs more than replacing it.
Common signs it’s time for flat roof replacement:
You’re dealing with recurring leaks in multiple areas
Ponding water remains on the roof 48 hours after rain
Membrane is cracked, brittle, or shrinking
Blisters, alligatoring, or exposed reinforcement in the field
Insulation is wet in several areas
Roof is at or past its expected service life
You’ve spent heavily on repairs with no lasting improvement
We’ll perform a full inspection, including hands-on measurements and, when needed, roof core analysis to determine whether your roof can be saved or if full replacement is the smarter long-term move.
Why We Replace Flat Roofs With Single-Ply PVC Systems
Not all flat roof systems are created equal. We’ve seen how Colorado’s sun, hail, and temperature swings break down older systems like BUR, modified bitumen, TPO, and EPDM. That’s why Royalty Roofing replaces flat roofs with PVC — a system proven to perform in demanding conditions.
Benefits of PVC for flat commercial roofs:
Heat-welded seams for long-lasting, watertight performance
Highly reflective surface to reduce cooling costs
Excellent resistance to UV, chemicals, and rooftop equipment heat
Compatible with complex roof layouts and multiple penetrations
Lower ongoing maintenance compared to many older systems
If your roof isn’t PVC yet, we’ll replace it with a PVC system that’s easier to maintain and better suited to Colorado’s climate.

Can you replace my existing BUR, modified bitumen, TPO, or EPDM roof?
Yes. We routinely replace older BUR, modified bitumen, TPO, and EPDM systems with new PVC flat roof systems that offer better performance and lower long-term maintenance.
How long does a flat roof replacement take?
Most commercial flat roof replacements take one to three weeks, depending on size, complexity, and weather. We phase work to keep your building dry and operations running.
Will my business need to shut down during the project?
In most cases, no. We coordinate with you on scheduling, access, and noise-sensitive areas so you can continue operating while we work.
Do you still repair flat roofs, or only replace them?
We do both. If your roof can be reliably repaired, we’ll recommend that first. When replacement is the better long-term option, we’ll explain why and show you the numbers. For repair options, see our Commercial Roof Repair page.
