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.
Insurance documentation available before work begins on any Longs commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
Membrane type and repair scope are itemized separately in every Flat Roof Repair estimate.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Longs Flat Roof Repair service for commercial and low-slope roofs.
We test repaired seams for a proper bond before considering the Flat Roof Repair job complete.
EPDM punctures and seam failures are patched with compatible materials, not a mismatched quick fix.
We identify why water is pooling — often a low spot or blocked drain — before recommending a solution.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Longs flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Longs commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
Technicians identify your membrane type before recommending any Flat Roof Repair repair method.
Repair scope and pricing are explained clearly so you can plan around business operations.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
