RE:  Letter of Satisfaction

Attn:  Joe Bader, Regional Sales Manager

After careful consideration of the different roofing materials and styles available; we were convinced that the aluminum roof system offered by Interlock Industries (Canada) Ltd. (hereafter referred to as “Interlock”) was the best choice for us.

Four years ago we moved into a 30 year old home, which has been in the family since it was built.  We knew that the original cedar shakes would need replacing; they had served
the homes’ inhabitants well but were nearing the end of their ‘life expectancy’.  We are a young family and so price was an important factor; however, we also plan on remaining
in this house for many years to come.  We decided that the investment in a “lifetime roof” was worth it for us, and we also appreciated the fact that it was more environmentally
friendly than an asphalt roof.

Our roof was installed over the course of ten days, only delayed a few days by two major snow storms.  The installation crew, led by James, was wonderful.  They worked long
and hard each day, they were considerate, conscientious, and personable; I would recommend James to anyone interested in an Interlock roof.  

Likewise, we appreciated your willingness, Joe, to work with us throughout the process.  Your consideration of our queries and concerns was noted and valued.

We are the first homeowners, on our bay of ten homes, to re-roof from the original shakes; the black slate design looks terrific…we will undoubtedly be fielding queries about your product and company!

With thanks,

Darren & Lori
