Flat roofs aren't actually flat — they need at least a 1/4" per foot slope to drain. Ponding water is the #1 killer of Calgary flat roofs, accelerating membrane breakdown by 5–10×. Good Roofing services every flat-roof membrane in use across Calgary commercial and residential: TPO, EPDM, PVC, modified bitumen, built-up.

When repair makes sense vs. full recover
We do a free moisture scan before quoting. If under 15% of the field is wet and the membrane is structurally sound, repair or coating is right. If wet area is 15–25%, partial replacement of saturated zones. Above 25% wet, a full tear-off is the only long-term answer.
