Insurance documentation available before work begins on any Grindstone commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.

We test repaired seams for a proper bond before considering the Flat Roof Repair job complete.

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 Grindstone flat roof ponding and membrane stress.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.
