Metal roofing is your best choice for durability in Alberta’s climate. Metal roofing is only a good investment when it’s properly installed. We replaced a metal roof for a customer in Cremona, Alberta. The metal roofing they had in place had a long list of problems.
The red tape you see seals off the waterproof underlayment (not visible). Renoteck bends the edge where it meets the wood siding. Exposed fasteners are both unsightly and provide future leak point. Renoteck’s standing seam metal roof has no exposed fasteners.

- No Flashing around Chimney
- Debris caught in gap acts like a wick
- Siding warping from moisture damage
The waterproof underlayment provided by Renoteck carries a 35 year limited warranty. The material comes in 60″ widths to reduce the number of seams. Note how the roofing edges are folded. The final flashings will be installed over this edge, designed to keep water running away from roof openings like chimneys.
A proper installation starts on plywood with a proper waterproof underlayment. Don’t let a contractor tell you that it’s OK to install your new metal roof over existing asphalt shingles. You home should only have one roof at a time. An old shingle roof may have water-damage and rot that won’t go away if it’s covered up. Stripping your old roofing material allows us to properly inspect the foundation of your roof and determine if replacement plywood is required.
