Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.
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.
Membrane Flat Roof Repair credentials cover commercial licensing requirements across Lopez Island, WA.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Lopez Island Flat Roof Repair service for commercial and low-slope roofs.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
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 Lopez Island flat roof ponding and membrane stress.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.
Commercial Flat Roof Repair visits are scheduled around your operating hours whenever the situation allows.
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.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
TPO seam repair was clean, tested it before leaving to make sure it actually held.
