As the weather begins to warm but still dips below freezing, commercial roofs can show early warning signs of freeze/thaw stress before major leaks develop. Here’s what you should watch for, and how ASI can help.
Ponding Water After a Thaw
Standing water left on the roof after snow melts during the day is one of the biggest red flags. Ponding accelerates membrane fatigue, and when that water re-freezes, it can push at seams and roof edges.
Stains or Damp Spots Inside the Building
Found water stains on ceilings or around wall tops? Even small leaks from compromised membranes or flashing can cause interior damage if not addressed.
Loose or Deteriorated Flashing
Freeze/thaw cycles cause materials to expand and contract at different rates. Flashings, the waterproof seals around penetrations and roof edges, can become stressed and loosened over time.
Clogged Drains and Debris Build-Up
Blocked drains prevent meltwater from exiting the roof surface. This increases ponding and magnifies damage from freeze/thaw activity. Cleaning drains and scuppers is a simple step that can reduce risk.
Membrane Cracks or Blisters
Even minor splitting can let moisture find its way into insulation, transforming a small issue into a big problem if left unchecked.
ASI Can Help
A proactive commercial roof inspection with ASI can help catch these signs early. We’ll assess the condition of your membrane, seams, flashings, drains, and more, and tailor a recommendation that makes sense for your building’s maintenance plan.
