Insulated Roof Systems

Some homes in Minnesota ask their roof to do double duty: shed the weather and hold the warmth. Vaulted ceilings, converted attics, cabins with cathedral lines, these structures have no buffer attic, which makes the roof assembly itself the insulation. Getting it right is a specialty, and it is one of ours.

An insulated roof is built from the outside in with intention: ventilation cavity or radiant barrier, continuous rigid insulation or SIP panels, sealed seams, then the standing seam or stone-coated surface. The goal is a roof assembly that performs like a thermos, warm in February, cool in July, with no cold corners drafting over the cathedral ceiling.

The enemy is the shortcut. Compressed fiberglass over an unvented cathedral ceiling is how ice dams are manufactured indoors. We design assemblies with calculated R-values, sealed penetrations, and vapor control placed correctly, then verify with infrared imaging before the surface goes on, so the family room below stays at one temperature all winter.

Projects this year include a lake cabin in Crosslake whose owners traded icy ceiling corners for sock-foot comfort, and a modern infill in Northeast Minneapolis where the exposed rafters demanded both beauty and physics. Both got standing seam over engineered assemblies, and both owners report the thermostat has become boring.

If your cathedral ceiling fights back every winter, ask for an insulated roof assessment. The inspection is free; the comfort is permanent.
