Commercial Roof Maintenance

Quick Answer: TPO and EPDM membrane maintenance in Calgary involves annual cleaning to remove biological growth and contamination, quarterly seam inspection, and immediate repair of any punctures or bruises. Use low-pressure water and manufacturer-approved cleaners only; never pressure wash above 1,200 psi or use solvents not specified by the membrane manufacturer. Proper care extends single-ply system life to the full 25 to 30-year manufacturer rating. Single-ply membrane sy

Quick Answer: Calgary commercial roofs need quarterly inspections aligned to climate stress windows: Q1 (January/February) covers mid-winter snow load and Chinook damage; Q2 (April/May) covers spring assessment after snowmelt; Q3 (July/August) covers post-hail and UV inspection; Q4 (October/November) covers pre-winter readiness. Each quarter has 6 to 10 documented tasks. Total annual time on a 20,000 sq. ft. building runs 16 to 32 service hours. A quarterly maintenance schedu

Quick Answer: Commercial flat roofs require roughly 2 to 3 times the maintenance frequency of pitched residential roofs because water doesn't shed by gravity. Ponding stresses membrane seams, UV exposure degrades sealants faster on a horizontal surface, and rooftop equipment concentrates foot traffic and mechanical wear. Calgary's freeze-thaw cycling and hail frequency amplify all four factors. Quarterly inspection is the commercial standard; bi-annual is the residential stan

Quick Answer: Calgary commercial roof maintenance requires a quarterly inspection cadence plus event-driven checks after hailstorms, wind events, and heavy snow loading. Annual contracted maintenance costs $0.08 to $0.25 per square foot depending on system type and scope. Core tasks include membrane inspection, drainage clearance, sealant verification at penetrations, HVAC curb checks, and snow load monitoring. Skipping quarterly maintenance shortens flat-roof system life by
