Certification & Workmanship

Peter & Greg Walker Contracting pride our self on the consistency of our quality through internal (see training centre) and external training. The performance of the materials is a direct function of the workmanship with which they were installed. The roofing industry in Ontario is not regulated like plumbers or electricians, which require standard training. The resulting quality deficiencies can be seen by the significant failure rate of the companies involved and the roofs installed (see Case Studies and How long does a roof last?).

Peter & Greg Walker Contracting Inc. have selected CertainTeed roofing products because of their commitment and support to roofing contractors. We insist that our staff complete all levels of training provided by CertainTeed, thereby certifying our company as a Select Shingle Roofer. As a Select Shingle Roofer, Peter & Greg Walker Contracting are in the top 1% of their profession in North America.

With over 100 years in the business, CertainTeed produces superior shingles and back them with their SureStart™ warranty. An upgraded warranty is available, provided the roofing contractor is a Select Shingle Roofer. Through their Master Shingle Applicator and Quality Master Certification programs, CertainTeed provides extensive training and independent testing for our roof mechanics, foremen and estimators.
