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.
Every Flat Roof Repair technician carries current Crabtree, OR licensing for commercial roofing work.
Local Crabtree dispatch minimizes business disruption with scheduling around your operating hours.
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 Crabtree Flat Roof Repair service for commercial and low-slope roofs.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
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.
Modified bitumen blisters and seam issues are repaired using proper torch-down or cold-adhesive technique depending on the situation.
Clogged or damaged drains are a leading cause of Crabtree flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Crabtree 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.
Drainage and ponding issues are assessed alongside any visible membrane damage.
Repaired seams are tested for a proper bond before we leave the site.
