Flat and low-slope sections — additions, garages, laundry rooms, dormers — fail fast when they're installed without proper slope and membrane technique. We specialize in torch-applied modified bitumen systems, built in multiple plies for the kind of sustained coastal rain this roof type sees every winter.
If your flat roof is already showing ponding water, bubbling, or a slow interior leak, we can usually pinpoint the cause during a single inspection visit.
Multi-ply torch-on systems built for zero-slope and low-slope sections.
We check drainage, existing membrane condition, and whether tapered insulation is needed.
Deck or existing surface cleaned, repaired, and primed for full membrane adhesion.
Base sheet and cap sheet torch-welded in overlapping courses for a continuous membrane.
Parapets, drains and walls flashed and sealed, then a final water-test walkthrough.
Torch-on modified bitumen is a heat-welded membrane system designed for flat or very low-slope roofs, where shingles can't properly shed water. Most homes use shingles on the main slopes and torch-on for flat sections like additions or garages.
Ponding usually means the roof lacks proper slope toward the drains, often from an older or improperly tapered install. We can add tapered insulation during a re-roof to correct the drainage.
A properly installed multi-ply torch-on system typically lasts 15–20+ years with basic maintenance — regular debris clearing and periodic inspection of seams and flashing.
In many cases yes, especially for isolated membrane damage or flashing failure. We'll inspect and tell you honestly whether a repair or full replacement makes more sense.
