Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Colton, not general shingle work applied to a flat surface.


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 Colton commercial property.
Local Colton dispatch minimizes business disruption with scheduling around your operating hours.
No surprise costs once we're already on the roof mid-repair.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Here's what falls under our Colton 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.
We identify the membrane type first, since EPDM and TPO repairs use different adhesive systems.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Colton flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Colton 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.
