Prevent Winter Freezes With Immediate Torch On Roofing Services

Citadel Roof & Building Maintenance • October 20, 2026

Waiting until a deep winter freeze hits Surrey to inspect your commercial property guarantees you will face massive interior leaks when the ice finally thaws. Facility managers frequently ignore their aging flat roofs, assuming the membrane will survive one more brutal winter. Citadel Roof & Building Maintenance monitors the coastal climate constantly to ensure your building envelope is sealed tight. Securing your torch on roofing services before the ice arrives ensures your structure sheds water safely all year.


Applying heavy bitumen membranes in changing weather requires highly specific trade knowledge regarding substrate moisture. Wet autumn snow will freeze against unsealed roof penetrations, physically ripping the flashing away from the building. Following a strict sequential schedule guarantees your commercial assets remain fully waterproofed.

Stage 1: Assess The Membrane Integrity


Before the snow flies, we evaluate how the harsh summer sun has impacted your existing flat roof materials.


  • Blister Inspections: We look for large bubbles under the membrane, which indicates that trapped moisture is trying to escape from the insulation layers.
  • Granule Loss: We check the top sheet for bald spots where the protective colored granules have washed away, leaving the bitumen exposed to UV damage.
  • Seam Probing: Our crews use metal picks to gently test the welded overlaps of the membrane to ensure the seams have not separated.


Stage 2: Schedule Your Installation Early


The rapidly shrinking autumn calendar means you must secure a firm execution plan before freezing temperatures halt major commercial installations entirely.


  • Prioritize Critical Zones: If a full replacement is not in the budget, we schedule targeted patches for the most vulnerable areas around HVAC units and scuppers.
  • Coordinate With Tenants: We build a timeline that minimizes loud machinery noise during peak business hours for the businesses operating below.
  • Secure Materials: Booking early ensures we have the necessary Soprema two-layer or three-layer systems staged in our warehouse and ready to deploy.


This strict commitment to reliable commercial execution is something our strata and corporate clients depend on.


►Client Experience: Lifelonglearning shared "Citadel Roofing came out to our Surrey home to install fire membrane on our somewhat complicated upper deck lined with stucco. Great job."


Relying on a company that proactively manages complex details keeps your project moving forward safely, just as this client noted.


Stage 3: Protect Exposed Structural Elements


When temperatures drop rapidly, extra precautions are required to ensure the roof penetrations and plumbing lines do not fail.


  • Sealing Pitch Pockets: We pour fresh liquid sealant into the metal pitch pockets that surround electrical conduits protruding through the roof deck.
  • Clearing Overhangs: We cut back heavy tree branches hanging over the flat roof to prevent them from snapping under the weight of winter ice and puncturing the membrane.
  • Insulating Vents: We verify that the metal flashing collars around plumbing exhaust vents are secure to prevent driving blizzards from pushing snow into the attic space.


► The single most important urgency fact: If water gets under a failing flat roof seam and freezes overnight, the expanding ice acts like a crowbar, ripping the entire roofing ply wide open and causing a massive interior flood when the sun rises.


Frequently Asked Questions


How do you protect exterior building pipes from freezing?


Commercial buildings often feature exposed rooftop water lines or fire suppression pipes. You must wrap these exterior pipes in heavy duty closed cell foam insulation and encase them in a waterproof aluminum or PVC jacket to block the freezing coastal winds.


What happens when commercial building pipes freeze?


When the water inside an uninsulated rooftop pipe freezes, the ice expands with immense force and shatters the cast iron or copper casing. When the ice thaws, hundreds of gallons of pressurized water dump directly onto the roof membrane and cascade down the side of the building.


Do building maintenance companies winterize plumbing?


Yes, proactive building maintenance involves a strict winterization protocol. We drain all exterior hose bibs, blow compressed air through exposed irrigation lines, and inspect the heat trace tape on vital rooftop plumbing to ensure everything is ready for sub zero temperatures.

You should not let another freezing winter degrade the structural integrity of your commercial facility.
