Low-slope roofs depend on drainage
Ponding, blocked drains, scuppers, penetrations, seams and flashing can all contribute to leaks. The City of Concord's roof guidance specifically notes checking flat roofs after heavy snowfall and during thaws because ice or snow can block drainage and allow water to build up.
Maintenance can reveal problems early
Scheduled visual checks can identify debris, damaged membrane areas, deteriorated sealants, drainage restrictions and changes around rooftop equipment before they become larger leak events.

☎ 603-633-1712Winter loading is a safety issue
Heavy snow and ice can create structural concerns, especially on some large-span or low-slope structures. If unusual deflection, cracking, popping sounds or other warning signs suggest structural distress, keep people out of unsafe areas and seek appropriate professional/structural guidance rather than climbing onto the roof.
Scope varies by roof system
Commercial roofing may involve membranes, metal, coatings or other systems. Call with the building type, approximate roof size if known, current leak symptoms and existing roof type so project fit can be discussed.
