The contract between St. George’s Church and Interlock Industries (Ont.) Inc. for the restoration of the Church roof, including new vapour barrier, insulation, ventilation and slate-pattern aluminum shingles, is now complete, and I wanted to express to you our satisfaction with the entire project. Interlock finished the work ahead of schedule and under budget, which is much appreciated. The staff from Interlock, with whom we were associated, were very professional and competent. John Reeves, your sales representative who responded to our RFP, was well informed as to our requirements and provided us with a very comprehensive and competitive quotation. Your site representatives, Sheldon Maddox, Supervisor; Tony Lupton, Site Superintendent and Toma Gravelle, Lead Installer, were all very accommodating and proficient. They provided us with good advice and were very responsive to our various requests. Interlock is very fortunate to have a staff of their calibre. The materials that you used were of the highest quality. I recognize that the ventilated, insulated plywood used for the insulation of the roof and the slate-pattern aluminum shingles were the materials that were specified in the original quotation, and we are very satisfied with this material. However, what particularly impressed me was your voluntary use of the high-quality RoofTopGuard II vapour barrier that your staff felt would give us a better end product, given the site conditions. This material upgrade clearly demonstrated the concern that Interlock has for the quality of work they do, and your dedication is sincerely appreciated. I would not hesitate to recommend Interlock to any person or organization investigating the restoration of their roof with a high-quality product installed by professionals. Thank you!
Very truly, R.J. Henderson.
