Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.


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 Redgranite commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
No surprise costs once we're already on the roof mid-repair.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Most Redgranite flat roof issues combine two or three of these elements, which is why a full inspection matters.
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.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Redgranite flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Redgranite commercial roof leaks that general roofers often overlook.

Commercial Flat Roof Repair visits are scheduled around your operating hours whenever the situation allows.
Technicians identify your membrane type before recommending any Flat Roof Repair repair method.
You receive a written estimate covering membrane repair or drainage correction before work begins.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.

They tested the seam repair with water before considering the job done.
