Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Williston, 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.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Williston business operations.
Insurance documentation available before work begins on any Williston 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.
Flat roof issues cover a specific range of membrane and drainage problems — here's our Flat Roof Repair scope.
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.
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 Williston flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Williston commercial roof leaks that general roofers often overlook.
We start by discussing the issue — ponding, active leak, or visible membrane damage.
On-site assessment identifies the membrane type and the actual cause of the issue.
Drainage and ponding issues are assessed alongside any visible membrane damage.
Repaired seams are tested for a proper bond before we leave the site.
TPO seam repair was clean, tested it before leaving to make sure it actually held.
