Rapid, professional leak response, any time, any weather
When water is entering the building, minutes matter. CMP Roofing’s emergency team prioritizes same-day, after-hours, and weekend calls across Calgary. We stabilize active leaks on TPO, EPDM, SBS-modified bitumen, and BUR (tar & gravel) systems, prevent interior damage, and outline clear next steps for a permanent fix.
What we do on the first visit
- Safety & access – Secure roof access, set up fall protection, and isolate affected areas below.
- Leak tracing – Inspect the interior and roof to pinpoint the source (seams, flashings, drains, penetrations).
- Stop the water – Apply system-specific emergency measures:
- Heat-weld patches on TPO
- Seam/cover tape and primer on EPDM
- Torch-applied cap patches on SBS
- Cold-applied mastic & ply repairs on BUR
- Clear plugged drains/scuppers, temporary diverters, snow/ice relief when safe
- Document & advise – Photo report with cause, temporary repair details, and options: targeted repair, section replacement, or full system upgrade.
- Plan the permanent fix – Scope and quote scheduled promptly once weather and site conditions allow.
Common flat-roof leak sources we solve
- Split or unsealed field seams and end laps
- Open or incompatible flashing at curbs, walls, and parapets
- Pitch pans and penetration details failing or cracked
- Clogged drains and scuppers causing ponding/overflow
- HVAC and conduit penetrations, loose fasteners, or hail punctures
- Aging BUR with alligatoring, blisters, or open gravel stops
Keep damage down before we arrive
- Place buckets/tarps and move valuables out of drip lines.
- Mark the ceiling where you see water—this speeds diagnosis.
- If safe, provide roof keys/access and notify on-site staff.
- Avoid cutting the ceiling unless directed; it can spread damage.
After the emergency: fix it for good
Emergency patches are meant to keep you dry. For a lasting solution, we’ll recommend the best path:
- Targeted repair or sectional replacement for localized failures – see Flat Roof Replacement
- System upgrades to modern membranes – see New Flat Roofs
- Preventative care to catch issues early – see Maintenance & Asset Plans
- Planning for solar readiness during repairs or reroofing – see Solar-Ready Roofing
