Our first exposure to Interlock Roofing was when Brad knocked at the door, having been referred by a neighbour who knew we wanted a new roof.

Brad explained in detail about the roof, about how it was priced, and when it would be done. Installation was done in March, as scheduled and took 7 1/2 days.

Both workers were friendly, neat and professional having worked for Interlock for many years. They threw the old shakes directly into the bin, so there was no mess around the house and to ensure there would no problems later, they checked on the attic vents and cleared those partially blocked.

We like the look and colour of the Interlock roof and it is admired by passer-by’s who often stop to ask about it.

We have no hesitation in recommending it to others.

The Interlock Roofing System was delivered and installed on time in spite of a delay in startup due to rain and another day delay due to rain after half the roof was done.
The crew was courteous and friendly and cleaned up at the end of every day.  I was very satisfied that the place was left tidy and clean after final cleanup.
I recommend Interlock Roofing to anyone wanting an impressive nice looking roof.

We have already noticed a difference in my house temperature. The workers were very polite and courteous.

Brad came by a couple of times to make sure everything was good. We would recommend this company to anyone looking for a new permanent, maintenance free roof.
