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/). ## Three mill towns joined as Cambridge Cambridge was formed in January 1973 by joining Galt, Preston and Hespeler, three river towns with their own mills, main streets and housing. Galt's factories ran on Grand River power from the 1840s, Preston made flour, furniture and stoves, and Hespeler was a textile town. Toyota opened its plant in 1988. The census shows about 48% of homes were built before 1981, and about a quarter are from 2001 onward. This history leaves several layers of roofing. In West Galt, including the Dickson Hill heritage district, late nineteenth-century homes and later rear additions often have low-slope sections tied into older brick walls. Old mill and factory buildings along the river were built with large flat or low-pitched roofs. Industrial and distribution buildings near the auto sector add big low-slope roofs, while the housing built since 2001, about a quarter of the stock, often includes townhouse blocks with membrane roofs. A repair here starts with working out which era of building you are dealing with. ## Cambridge weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.
