Solving Complex Roof Geometry
One of the most unique features on this project was the breezeway, which included an irregular hip where two roof planes met at different angles. Instead of relying on a patchwork of valley flashing and hip caps, the Axtell crew designed custom tapered panels that tie everything together cleanly. Fewer seams and fewer awkward transitions mean fewer weak points over the life of the roof.
Building for Snow, Ice and Drainage
High country roofs live or die in the roof valleys; a weak point on any home, but especially in snow and ice climates. Here, Axtell used 24-inch wide valley pans paired with 240-volt metal heat cable channels to create a controlled drainage path. Around those valleys, the mechanical lock seams were “double-locked” to create a watertight, ice resistant assembly.
On top of that, a full S-5! ColorGard snow retention system manages how snow sheds and melts, protecting decks, walkways and landscaping below.
Twelve inches on either side of the valley allowed for a complete 24-inch wide open valley with Gunnison Sheet Metal’s custom CNC metal heat tape housing. A wide valley and applied heat tape allow inevitable snow and ice to accumulate on low pitches while maintaining space to hold that expanding ice and water without pressure against accompanying valley roof panels, all the while encouraging melt with the applied heat tape.
