Interlock Metal Roofing - ON

This review is for work done by Interlock Industries (ONT) Inc based in Mississauga. I did A LOT of research on the material options (aluminum, metal, and asphalt shingles). I chose aluminum shingles mostly because I do not intend on selling my house and I do not want to re-roof again in retirement. Also, I am very skeptical about all roofing warranties so hopefully I will never need to refer to mine.
Dave provided a competitive quote and I liked the underlayment and aluminum shingle samples he showed me. I chose to have a ridge vent installed with snow guards and a skylight too. The work was to start and end within the month of April. I was told "Tony" will be the installer. I got a call informing me of the exact start date and when the date came, Tony worked from morning until evening almost everyday until he finished. Everyday, Tony did a satisfactory clean up around the house before he left. In my opinion, Tony is a very honest hardworking and skilled man. Look at the pictures to see his work.
I was skeptical about the ridge vent letting moisture and heat out but it seems to be working fine. The snow guards are doing their job too.
Overall, I would recommend aluminum roofing from this company. I like the look and the satisfaction of knowing that my shingles won't blow up during a major storm as my asphalt shingles did last summer. I really can't see how any water can penetrate the roof and I don't even hear the rain hitting the roof. Flashing appears to be done really well and very clean. My only recommendation would be for Tony to start teaching his skill to some new installers rather than doing everything himself.
Raccoons should have much difficultly walking up there and most surprisingly so far...the inside of my house seemed cooler during the summer. Everyone should at least ask for info and a quote.
