What is flat roof repair?

Flat roof repair fixes leaks on low-slope membrane systems. EPDM, TPO, PVC, and modified bitumen roofs rely on watertight seams and proper drainage. When something fails, water gets in. Most flat roof leaks start at seams, penetrations (vents, skylights), or drains. Ponding water—standing 48 hours or longer—accelerates damage.

Common flat roof repairs include:

Seam failures between membrane sheets

Punctures and tears from foot traffic or debris

Flashing problems at chimneys, vents, curbs

Drain and scupper clogs or separation

Blistering on modified bitumen

Fastener back-out at roof edges

What flat roof problems do roofing contractors fix?

Seam failure — Membrane sheets separate due to poor installation or thermal movement. Water spreads across the deck.

Punctures and tears — Foot traffic, branches, or HVAC work create holes. Small punctures become bigger problems when water freezes.

Flashing at penetrations — Chimneys, vents, skylights need flashing tied to the membrane. Separation or cracks let water inside.

Drain clogs — Leaves and debris block drains. Water backs up, ponds, and finds weak spots.

Blistering — Modified bitumen develops bubbles or cracked texture indicating breakdown.

Fastener back-out — Edge fasteners loosen over time. Wind lifts the membrane.

What's the repair process for flat roofs?

Protect area — Tarps go down around work zones. Pathways stay clear.

Stabilize leaks — Active leaks get temporary patches so interiors don't take more damage.

Remove damaged material — Cut out failed membrane, flashing, or sealant. Create clean bonding surfaces.

Check deck — Inspect for soft spots, rot, or water damage. Fix compromised areas before membrane goes back.

Deck condition is the wildcard. You don't know what's underneath until membrane comes off. Soft deck gets fixed before repair proceeds.

Install compatible membrane — TPO/PVC gets heat-welded. EPDM uses primer and tape. Match existing materials.

Integration check — Verify clean integration, proper overlap, secure fasteners. Document with photos.

How do professional roofing contractors keep job sites clean?

Ground protection — Tarps catch debris, protect landscaping and driveways.

Daily magnet sweeps — Metal fasteners and nails pulled from yards, walkways, driveways every day.

Same-day haul — Old membrane and materials leave the property daily.

Drain clearing — Gutters and scuppers cleared before final sign-off.

How long does flat roof repair take and what affects cost?

Simple repairs → Half-day to one day

Small seam repairs, single punctures, isolated flashing fixes.

Multiple areas, larger membrane sections, deck work needed.

Complex repairs → Two to four days

Widespread seam failure, ponding fixes with new slope, significant deck replacement.

Cost drivers:

Membrane type (TPO/PVC cost more than EPDM)

Roof access and height

Extent of damage

Deck condition

Ponding water issues requiring drainage fixes

Weather affects schedules. Rain, snow, high winds stop work. Ponding water (48+ hours standing) signals drainage problems that may extend scope.

How do you prevent flat roof leaks?

Clear drains twice yearly — Spring and fall. Remove leaves, debris, sediment so water flows.

Check for positive slope — Water shouldn't pond for days. Poor drainage needs fixing before membrane fails.

Annual penetration checks — Inspect vents, skylights, curbs, chimneys yearly. Catch small separations early.
