Flat Roof Challenges in Greater Moncton — What You're Dealing With
Greater Moncton's older residential and commercial building stock — much of it built in the 1960s through 1990s — features a significant proportion of flat and low-slope roofs. While flat roofs can be excellent in the right climate, New Brunswick's repeated freeze-thaw cycles create specific challenges: membrane cracking, pooling water that freezes and expands seams, and drainage systems that clog with ice.
The most common flat roof failures in Moncton we see: blistering and cracking in modified bitumen membranes from UV + freeze-thaw stress; seam separation in older EPDM systems; ponding water creating structural load issues; and inadequate drainage causing ice damming along perimeter edges. Most of these are repairable if caught early — full replacement becomes necessary when the membrane has reached end of life or when structural decking is compromised.
Flat roof repair costs in Moncton range from $150–$800 per sq metre for patches and section repairs, to $13,000–$23,000 for full replacement on a typical residential flat roof (1,000 sq ft). Commercial systems with extended warranties (MRGNB-backed 10–20 year programs using Soprema, Carlisle Syntec, or Sika Sarnafil) run higher but include post-installation quality observation.
