Winnipeg doesn’t just test people—it brutalizes roofs. Sub‑zero cold, freeze‑thaw swings, and prairie wind gusts all conspire to shorten shingle life. After the last snowdrift melts, grab a pair of binoculars (or your phone’s zoom lens) and look for these tell‑tale trouble signs:

Red Flag	Why It Matters	Quick Homeowner Check
Rippled or Buckled Shingles	Moisture trapped beneath shingles expands when it freezes, warping the surface.	Stand back and scan for waves instead of a flat plane.
Granule “Beach” in the Gutters	Those gritty specks are your shingles’ UV armor; once they go, asphalt dries and cracks.	Put on gloves and run your hand along the gutter bottom—grit means aging shingles.
Ice‑Dam Scarring	Last winter’s ice dams leave dark, algae‑friendly lines near the eaves.	If the staining stops at the same height all around, it’s from ice dams, not water runoff.
Popped or Rusty Nails	Nails back themselves out as the decking contracts in prolonged cold.	Look for tiny bright dots (new pops) or rust streaks (older pops).
Soft Decking Underfoot	Walking on the roof and feeling “spongy” means rotted sheathing.	From inside the attic, press a screwdriver tip against the decking—if it sinks easily, wood is compromised.

Why jumping on these issues matters: a $200‑$300 spot repair today beats a $7 000+ re‑deck and re‑shingle job next season. Dillon & Sons Roofing offers Spring Health‑Check Inspections that include drone footage, moisture readings, and a written action plan you’ll actually understand.

Pro Tip: Schedule inspections just after snowmelt but before heavy spring rains. Small leaks are visible, and crews can still work safely on cooler surfaces.
