Commercial Flat Roof Questions
Practical answers on systems, estimates, moisture, maintenance and the next step for your Edmonton-area building.
Choosing a roofing system
SBS, EPDM, TPO or BUR — which is best?
There is no universal winner. SBS and BUR provide multi-ply construction; EPDM covers large, simple roofs in wide sheets; TPO offers welded seams and a reflective surface. Deck condition, drainage, equipment, traffic and budget guide the recommendation.
Do you provide residential roofing?
No. Carriere specializes in commercial flat and low-slope roofing: SBS torch-on, BUR, EPDM and TPO.
How long does a commercial flat roof last?
System, installation quality and maintenance all matter. Regular inspections, prompt repairs and clear drainage help extend service life. Alberta freeze-thaw conditions make small unresolved defects important.
Repair or replace — how do I decide?
Start with documented conditions and an infrared scan. Localized moisture and an otherwise sound membrane can favour targeted repairs. Widespread moisture, failing seams or a compromised deck may point toward replacement.
Leaks, moisture & maintenance
My roof is leaking. What should I do?
Call 780-405-4440 for 24/7 emergency service. Describe the building, where water is entering and any immediate concerns. Diagnosis helps distinguish temporary protection from the permanent repair.
What does an infrared inspection show?
Thermal imaging reveals heat differences that can indicate trapped moisture. Scan findings are paired with visible-light photographs and verified with probes or core cuts where appropriate.
Is standing water a concern?
Standing water beyond 48 hours is treated as an action item. Drainage, blocked drains, scuppers and slope should be assessed rather than assuming the membrane alone is the problem.
How often should a commercial roof be inspected?
Spring and fall inspections help identify winter damage and prepare for freeze-thaw. Roofs with heavy traffic, equipment or known drainage issues may need more frequent checks.
What is in a roof condition report?
Dated photographs, infrared findings, a plain-language assessment, prioritized recommendations and drainage observations provide evidence for maintenance and capital planning.
Estimates & the Roof Watcher pilot
How much will my roof cost?
The roof area, chosen system, deck condition, insulation, access and flashing complexity all affect the scope. An on-roof inspection with infrared and photographs comes before an itemized estimate.
What is Roof Watcher?
A planned founding-customer pilot for documented commercial roof asset management: inspection records, roof history, maintenance planning and repair tracking. Contact Carriere to discuss pilot availability and scope.
What are the planned annual prices?
Essential: $2,000/year + GST. Professional: $4,000/year + GST. Premium Platinum: $6,500/year + GST. Founding-customer pricing is locked during the pilot. Repairs are quoted separately.
