Common Flat Roof Problems and How to Fix Them

Flat and low-slope roofs are common on additions, porches and some New Jersey homes and buildings. They're durable when done right, but they have their own set of common problems.

Ponding Water

Because flat roofs don't shed water as quickly as pitched roofs, water can pool in low spots. Standing water accelerates wear and finds any weakness. Proper slope and drainage design prevent it.

Seam and Flashing Failures

Most flat roof leaks happen at seams, flashing, and transitions to walls or pitched sections. These details need to be installed and maintained correctly, because they're where water gets in.

Blistering and Cracking

Over time, sun and temperature swings cause some flat roof membranes to blister or crack. Small areas can be repaired; widespread failure signals it's time for replacement.

The Right Repair

Flat roofing is a specialized craft, different from shingle roofing. Many general roofers avoid it, which is why so many flat sections leak. We handle flat roofing as a core service and detail the seams, flashing and drainage correctly.
