Our Experience is
The depth of experience and knowledge that Conestoga Roofing has in replacing, repairing, and new roof construction, along with our solid reputation for excellent workmanship means that our customers are fully satisfied with every project, at every step, from detailed estimates through to final clean up.
Commercial and industrial roofing requires a full complement of specialized equipment and vehicles. As a fully outfitted roofing contractor, Conestoga Roofing uses industrial roof conveyors, asphalt tankers, automatic welders, odorless kettles, and a complete “roll off” system with disposal bins for removing debris and the delivery of gravel and material.
Conestoga Roofing is a continuously growing company, and we are maximizing our construction-related skills by offering a variety of related services under our “Conestoga Umbrella”. We are the proud operators of Roof Rock Removal Inc. where we have newly purchased a roof rock vacuum system which reduces labour costs as well as airborne dust and debris. We also are able to service our clients with services from Conestoga Waterproofing Ltd. to ensure watertight solutions and project longevity. Additionally, we operate Conestoga Solar Inc. which is a full turnkey photovoltaic business specializing in large commercial FIT projects.
