Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Mercer Island, not general shingle work applied to a flat surface.
We carry compatible repair materials for multiple membrane brands, since mismatched patch material is a common cause of repeat flat roof failures.
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 Mercer Island commercial property.
Local Mercer Island dispatch minimizes business disruption with scheduling around your operating hours.
Membrane type and repair scope are itemized separately in every Flat Roof Repair estimate.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Most Mercer Island flat roof issues combine two or three of these elements, which is why a full inspection matters.
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.
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 Mercer Island flat roof ponding and membrane stress.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.
We start by discussing the issue — ponding, active leak, or visible membrane damage.
A technician inspects the membrane system, checking seams, drains, and any ponding areas.
You receive a written estimate covering membrane repair or drainage correction before work begins.
A completed Flat Roof Repair includes a walkthrough of what was repaired and why.
