Metal Shingles Nepean, ON Review 🇨🇦 — September 27, 2018 | Interlock®

Quality of service was poor, communication was poor, and there was a lack of quality control. We had two serious problems with the installation. 1. Interlock made a scheduling error that left our newly rebuilt roof exposed without a membrane when a massive storm was expected in the evening – we had a different contractor rush to install a temporary membrane before the storm (Interlock partially covered our costs). 2. Ridge venting was completely botched. Two visits and several emails later the ridge was finally properly vented. However, the openings on the ridges are very poorly and unevenly cut, and cut marks are visible on the new trusses b/c a reciprocating saw was used instead of a circular saw.
