Benefits of Built Up Roofing
Time-tested technology. It's hard to argue with more than 100 years of history.
Redundancy Built up roofs provide many layers of protection, so if the top layer is damaged, the additional layers below will continue to protect the building from water intrusion.
Guarantees/WarrantiesBUR systems may be eligible for guarantees or warranties of up to 20 years, depending on the materials used and the system installed. Check with the manufacturer for guarantee/warraaty requirements and coverage.
Reflective cap sheets availableModules can be custom cut to create natural-looking green roofs with sweeping curves and full vegetation.
