Metal Shingles Markham, ON Review 🇨🇦 — October 25, 2021 | Interlock®
Markham, ON
What was involved in this Interlock® Slate roof installation in Markham, ON?
Interlock installed an Interlock® Slate system in Black on a home in Markham, ON, completed September 23, 2021. The project covered roughly 28 squares of roofing. Gnana N. rated the work 4 out of 5 in an independent survey conducted by GuildQuality on October 25, 2021. Likely To Recommend scored 4 out of 5, with the homeowner noting: “The installation took a long time.” The installation was carried out by Interlock Roofing. The roof has been in place 4 years and remains under Interlock's lifetime limited warranty.
The installation took a long time. Their communication and upholding their promises is most important. The salesperson should clearly acknowledge those promises. They don't know what they are doing. They need to acknowledge their procedures on how they are going to do them and explain what materials they are going to use. The demolition is most important. If they are going to show up with an iPad, they should show me how they are going to install the product. I do not know if this would be the first time they install the product using one nail only.
