Great experience with Gentech. These guys replaced our roof of 25 years in the Mississauga area. They provided the most comprehensive quote with pictures, details and options for us. The entire installation crew was knowledgeable, nice and professional in their work. Gentech did an excellent job on the full replacement of our old roof. We highly recommended this company -- Chris, owner.

Pretty good work. Secretary/whoever the women I spoke with on the phone multiple times was not very pleasant to talk to. Felt very unprofessional.

Great service and quality work. It was a pleasure working with the employees and management staff. They provide excellent service, quality work and fair pricing. I'm very glad we chose Gentech. Keep up the good work guys!!

Big thanks to everyone at Gentech Roofing for your amazing work. Id like to say first that this company is the most professional company we dealt with. The roofers are very kind and respectful people. Our office leak problem has been finally solved. Thanks Gentech, you guys rock!

Ok
