Permanent Attic Rain Repair in Calgary
Stop Attic Rain: Permanent Moisture, Mold & Frost Solutions in Calgary.
What Is Attic Rain?
Attic rain occurs when warm, moist air from your home escapes into your cold attic. During Alberta’s extreme cold snaps, this moisture freezes instantly upon hitting the roof deck, creating layers of frost that will eventually melt when the warm air from a poorly sealed vapor barrier makes it way in your attic.
Frost Formation
Warm, moist air from the living space (kitchens, bathrooms) rises through unsealed gaps and enters the cold attic space. Air Sealing, Home Envelope Failure.
Condensation & Freezing
When the warm air meets the cold roof deck (sheathing), it rapidly condensates and freezes solid, building up thick layers of frost. Frost on Roof Sheathing, Attic Condensation.
The False Leak
The sudden, massive volume of water overwhelms the attic, dripping onto ceilings and electrical fixtures, often mistaken for a roof leak. Ceiling Stains, Pot Light Drips.
The Thaw Trigger
Rapid temperature swings (like a Calgary Chinook or mild daytime sun) cause the large mass of ice to melt quickly and unpredictably. Chinook Effect, Rapid Thaw.
Do You See These Common Signs?
- Water Stains: Random, yellow/brown spots on the ceiling, often expanding after a cold snap.
- Frost Buildup: Visible white frost or ice layers on the underside of the roof deck or trusses in the attic.
- Fan & Vent Dripping: Water actively dripping from the bathroom fan or kitchen exhaust vent, especially in the morning
- Water pooling or dripping directly from recessed lighting fixtures—a sign of major air leakage.
- Wet Attic Hatch: Condensation (sweat) or ice forming around the attic access hatch or access stairs.
The 4-Point Inspection
01
Thermal Imaging Scan
We use industrial-grade thermal cameras to identify hidden heat loss and air leaks (bypasses) around light fixtures and walls that the naked eye can't see.
02
Insulation Depth Check
We measure your current insulation levels to calculate your effective R-Value. If it's below R-50, your attic is susceptible to heat escaping and melting frost.
03
Ventilation Audit
We calculate your attic's specific intake-to-exhaust ratio. If your vents are blocked or unbalanced, moisture gets trapped inside instead of flushing out.
04
Moisture Meter Reading
We scan your roof sheathing and wood framing for high moisture content. This tells us if the wood is compromised or at risk of mold growth.
