Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.


A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.
