Drains and flashings for heavy summer storms." url: https://flat-roof-repair.ca/locations/milton/ last_updated: 2026-10-23 --- # Flat roof repair in Milton We repair, replace and maintain flat roofs in Milton: houses, garages and additions, condo and apartment buildings, plazas, offices and warehouses. Send photos and a few details for a written quote. ## Flat roof services in Milton Milton has a lot of newer housing, and on newer flat roofs leaks usually start at details rather than the whole membrane: a terrace door, a rooftop unit or a drain on a roof that is otherwise sound. We find where the water gets in, fix that spot and tell you how much life the rest of the roof has. When a roof is past repair, we [replace it](https://flat-roof-repair.ca/services/flat-roof-replacement/) with EPDM, TPO, PVC or modified bitumen, and fix the [drainage](https://flat-roof-repair.ca/services/roof-drains-and-scuppers/) so water does not sit on the new membrane. Owners and property managers also book [inspections](https://flat-roof-repair.ca/services/flat-roof-inspection/) and [maintenance visits](https://flat-roof-repair.ca/services/flat-roof-maintenance/). ## New Milton and old Milton: two different roof eras Milton was a small mill town for most of its history. It was incorporated in 1857, and Old Milton was built mainly between 1850 and 1890, with a grist mill, woollen factory, tannery and foundry. P.L. Robertson moved its manufacturing to Milton in 1908. Growth was slow after 1979 for about twenty years, then picked up after the Big Pipe water project in 2002. Census data show that about 73% of homes were built in 2001 or later and only 19% before 1981. That gives Milton two very different roof stocks. In Old Milton and the 1960s Fallingbrook area, older brick houses and storefronts often have flat roofs over rear additions. Beaty, which started in 2001, then Dempsey, Clarke, Coates and Willmott, and the Boyne Survey neighbourhoods from 2015, are recent subdivisions with townhouse blocks whose membrane roofs are still fairly young. Milton Heights and the business land near the Niagara Escarpment hold automotive, manufacturing, distribution and food-production buildings, where very large low-slope roofs are the norm. ## Milton weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.

Leaves and grit in a drain basket are the most common cause of water backing up under flashings. ## Starting prices in Milton | Item | Starting price | |---|---| | [Small leak repair (patch, seam or puncture)](https://flat-roof-repair.ca/services/flat-roof-leak-repair/) | from $350 per repair | | [Flashing repair or replacement](https://flat-roof-repair.ca/services/flashing-and-seam-repair/) | from $500 per repair | | [Maintenance visit (drains, seams, flashings, photos)](https://flat-roof-repair.ca/services/flat-roof-maintenance/) | from $295 per visit | Starting prices in CAD before 13% HST, based on typical Ontario contractor rates (mostly Toronto and the GTA).

See [flashing leaks](https://flat-roof-repair.ca/problems/flashing-leaks/) and [clogged drains](https://flat-roof-repair.ca/problems/clogged-drains/). **Do I need a permit to replace a flat roof in Milton?** Check with the Milton building department.
