Flat roof contractors frequently work on commercial buildings, as the installation process is quick and cost-effective. Without a traditional pitch, however, roofing is susceptible to pooling water. Here’s what you should know about this problem and when to call a flat roof contractor for assistance. 

Why Is Pooling Water a Concern?

Puddles of water on a flat roof must be resolved to avoid structural damage. When water remains, it breaks down the membrane and reduces the life span of the roof.

These puddles can cause leaks, sagging, attract pests, and increase the risk of moss and algae growth. Over time, these pools of water combined with the elements and storm debris can make the roof dirty and visually unappealing. When left unattended for too long, puddles can lead to leaks that can cause damage to interior ceilings and walls. 

How Can You Prevent This From Happening?

During installation, flat roof contractors create subtle slopes to facilitate drainage. If pools are gathering in low points, plaster fills can eradicate the issue.

Other ways to prevent damage include clearing any blockages in existing drains and adding extra drains to facilitate the redirection of rainwater. The slight slope of a flat roof needs to be installed properly or you’ll end up with significant pooling on the surface. In this case, it may be necessary to repitch the area to maximize structural integrity and prevent water damage in the future.
