Send photos and a few details for a written quote. ## Flat roof services in Kitchener Many homes in Kitchener are rented, so a roof leak is often reported first by a tenant, then handled by a landlord or property manager. 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/). ## Berlin's factories and Kitchener's technology downtown Kitchener began as Ebytown in 1806 and was called Berlin until 1916, when it was renamed during the First World War. The railway arrived in 1856, it became a city in 1912, and manufacturing has long been central: the Dominion Tire Plant was built in 1912, and the Kaufman shoe and Arrow shirt factories have since been converted to lofts. Four business parks, including Bridgeport, Grand River West and Huron, hold much of today's industry. Census data show about 49% of homes were built before 1981 and 28% in 2001 or later. Downtown Kitchener has brick commercial buildings and former factories, such as the Lang Tannery, now used by digital media firms, where flat roofs over rear sections and low-slope roofs on large factory floors are common. Neighbourhoods such as Westmount, developed in the interwar and postwar periods, have older houses, while the newer parts of the city bring more recent construction. Large flat roofs on industrial buildings in the business parks, and a downtown building boom of new developments, mean the city has low-slope roofs of nearly every age. ## Kitchener weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.
