  Metal Shingles Whitby, ON Review 🇨🇦 — August 8, 2018 | Interlock®

  Review: August 8, 2018Completion: July 16, 2018

  Many nails were found around my property. I would recommend that this be addressed as I have a pool and nails/debris are an issue. As well, I had my eavstroughs cleaned, and aluminum was removed from there
