Letter of Recommendation

The installation of our Interlock Roof System was completed this week to our total satisfaction and expectation! The compliments of our new roof are just beginning to be received. Your installation crew of three young men, headed by Peter, are to be commended as they did an outstanding job of removing the old shingle roof, sheeting the roof surface with 1/2" CDX plywood prior to installing the interlocking aluminum panels of Tudor Brown.

Our 3,000 sq. ft. home has numerous hips and valleys making it a more complicated roofing system than normal, but your installation crew was able to complete the project within ten working days. The crew's work ethic elicited several admiring comments from neighbors.
One comment was, 'lt would be difficult to find a more hard working and thorough crew than what you had working on your home". We also appreciated the fact that the crew left the premises orderly after each day's work and completely removed all debris when the project was completed.

The entire process from the visit of your sales representative, Glen Caldwell, to the work phase of the installation crew was done most professionally. The end produet is a roof that reflects quality and one that we will not have to replace in our lifetime. Thank you.

Sincerely,
Denton Palmer
