Why Behlen Straight Wall Roofs Fail
Stitch & Support Bolt Failure
Gaskets on stitch bolts and structural bolts UV-degrade and fail building-wide — not just at isolated points. Every failed fastener is a penetration point.
Thermal Shock Is the Root Cause
Western Canada's extreme temperature swings create constant micro-movement at every connection point, working fasteners loose over time. Patching individual bolts does not stop the cycle.
Hidden Damage
Liner panels and loose-fill insulation make interior inspection extremely difficult. Leaks are often far more widespread than they appear from the ground.
High Fastener Volume
A Behlen roof has 30–50% more structural bolt and fastener connections than a standard screw-down metal roof of the same size — every one is a potential leak point.
Why Behlen Straight Wall Roofs Fail
Behlen's self-framing design uses corrugated steel panels as the load-bearing structure. After 20–50+ years of Western Canada's extreme thermal cycling, systemic failure is common — and it cannot be solved with conventional patching.

Three Standard Behlin Options
Three Standard Behlin Options
Stitch Bolt & Support Bolt Replacement
Removal of stitch bolts and supporting bolts throughout the building and replacement with oversized hardware.
- Addresses individual fastener locations at time of replacement
- Does not address root cause — thermal cycling continues
- Recurrence likely as thermal shock stresses new fasteners
- Very labour-intensive on a Behlen (30–50% more bolt points than a screw-down roof)
- Partial building disruption during bolt work
Complete Overlay System
Full overlay system installed over the existing Behlen structure. A new roof skin over the existing panels.
- Requires structural engineering review
- Significant cost and extended project coordination
- Adds substantial weight to the self-framing structure
- Does not address thermal movement at the fastener level
Full Tear-Off & Replacement
Complete removal of the existing roof system and full replacement with new panels and hardware.
- Maximum disruption — building out of service
- Highest cost of all options
- Complete building shutdown required
- Often not economically justified on older structures

How CCC/100 Works
A Two simultaneous mechanisms make CCC/100 different from any conventional repair approach.
Thermal Barrier
CCC/100's ceramic bead technology reduces roof surface temperature fluctuation by up to 90% — directly addressing the thermal shock that causes fastener loosening and seam failure on Behlen roofs.
Seamless Waterproof Membrane
A continuous skin applied over the entire roof surface — sealing every fastener, seam, ridge cap, and penetration simultaneously. No individual patch points. No future single-point failures.
Proprietary Formulation
CCC/100 is a proprietary Delta T formulation — not an off-the-shelf product. Developed specifically for the thermal cycling conditions of Western Canada's climate.
20-Year Material Warranty
3-year labour warranty. 20-year material warranty. Extends the service life of the existing structure for an additional 20+ years without further maintenance requirements.
