Keller Roofing is located in Exeter, Ontario (a few minutes north of London, Ontario.) Our location offers us access to the 401 corridor, which in turn puts us approximately one hour from locations such as Woodstock, Kitchener, Waterloo, Ingersoll and London. We also have traveled and installed roofing all over Southwestern Ontario from Windsor to Ottawa and have installed in the north such as North Bay and Sudbury and all points in between. We have been in business for 14 years and employ people with up to 35 years experience in the roofing field. more... See more text
