T. Simpson Roofing was founded in 1992 and quickly became the leading roofing contractor in York Region.  The company was incorporated in 2002 and has become the market leader from Barrie to Toronto winning many Readers' Choice awards.

T. Simpson Roofing has expanded its operations to include all eavestrough, siding, soffit and fascia needs.   In 2009, T.Simpson has expanded to include blown insulation amongst its services to better address their customers needs.  Customers can expect one stop shopping with each employee individually  trained in each aspect of the project.  

Over the years the company has installed over 12,000 roofs and has seen every situation immaginable so there is no roof that our experienced installers cannot handle.   From start to finish the customer's needs are the top priority of all our staff.  We believe this is what has made T.Simpson Roofing one of the GTA's largest and most respected roofing companies.
