The aluminum roof is definitely a premium product! It added to the value and the looks of the house. Derek, the salesman we worked with, provided all relevant information and he was extremely patient with us, as we had a million questions for him. Additionally, Jean-Francois and Matthieu did an excellent job with the installation as well as keeping things neat and tidy at the end of each day. The final look and performance of the product surpassed our expectations! Thank you Interlock.

    All I can say is "WOW"! Not only am I extremely impressed with the look, all our neighbours are as well. In addition to the look of the new roof, all the gentlemen and lady we dealt with, from the office staff, to the sales staff, to the field manager and to those on the roof (the installation professionals), were lovely. Dedication, dedication, dedication. Thanks to all for everything! Catherine Our additional requests, especially the removal of the shingles, added a considerable amount of time to the project, which was not a concern for us, as our timeline was somewhat flexible. However, because of these additional hours/days, and the scheduled work days for the installers (i.e., time off), the project "sat" stagnant for a number of days. Better planning regarding man-hours might be a consideration for Interlock Roofing. (Installers did ensure that there were no "open/uncovered" areas on the roof, for the days they were not on-site. For Interlock Roofing (IR): I realize I am in the wrong business! After speaking with a friend (a metal worker), as well as business owners who pay for experienced labour, it appears that IR makes an excellent profit in the aluminum roofing business, after paying for the materials, shipping, labour costs, etc. IR may get more business if they reduce their profit margins on either or both materials and labour. (Example: reduce costs by 20% could lead to 30+% more clients.) I also thing that the cost associated with removing shingles is quite high. I understand that removing shingles is an extra cost for the company, i.e., time for labour to remove the shingles, cover-up of roof should it rain )and then uncovering it to work on it), clean up of the shingles, roofing paper and nails, the disposal of them, etc., but $10k is a little exorbitant. It seems that IR charges such a high rate to remove the shingles so that clients will skip the option to remove the shingles, allowing IR to save time on each project, which in turn allows them to take on more jobs each season. (There still seems to be some controversy as to whether leaving old shingles, roofing paper, ice-shield, etc. on the roof and installing other shingles (metal or asphalt) over to of them is a good idea.) One last thing, a metal roof is not always a selling feature for a home, per the realtors I spoke with before deciding to go ahead with the metal roof, unless of course the new owner gets a 45 year warranty on it, (i.e., the original home owner, which paid to have the metal roof installed, sells the home five years after installing the roof). (Not a criticism, just reality, making home owners (at least the ones we talked to) question the need to put out a small fortune to re-roof their homes in metal.) All this to say, we do love it. Just thought I would share some of the discussions we had and heard of when deciding what material we wanted to use to re-roof our home. Thanks a million and Merry Christmas and Happy New Year.
