    We have been enjoying our Interlock roof for several months. The planning, purchasing, and installation experience was everything we expected it to be – superb. The original shingles, paper, and staples were removed. The two installers did these tasks without making a mess in the surrounding garden or the patio. A new waterproof barrier was laid out and the new aluminum shingles were installed.
