Send photos and a few details for a written quote. ## Flat roof services in Niagara Falls Much of Niagara Falls's housing is older, and older houses often have flat roofs over rear additions, porches and garages. Typical signs are a stain on the kitchen ceiling, water at a skylight or a roof with several worn layers. 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/). ## Tourist strip and industrial basins in Niagara Falls Niagara Falls grew from two towns, Clifton and Drummondville, which amalgamated in 1904. Cheap hydroelectric power drew electro-chemical and metallurgical industries in the early to mid-twentieth century, and industry began leaving in the 1970s and 1980s. Tourism then became the main revenue source, with casinos in the late 1990s and Niagara Fallsview in 2004. Chippawa, Willoughby and part of Crowland were added in 1970. Census data show about 61% of homes were built before 1981 and about 31% before 1961. Historic Drummondville, Stamford and the Queen Street district have older brick buildings and houses where flat roofs over rear additions and storefronts are often found. Clifton Hill and Fallsview are dominated by hotels, casinos, attractions and a convention centre, which typically have large flat or low-slope roofs with mechanical equipment on top. The Drummond, Grassybrook and Westlane industrial basins hold industrial buildings tied to the hydro-power era. Outlying Chippawa and Crowland add rural and suburban buildings of mixed ages. ## Niagara Falls weather and your flat roof Ontario's Building Code sets the climate values used to design roofs in each municipality.
