This company was contracted to do a shingle roof as part of the sale on our home 5 years ago. Our roof started leaking around the chimney so we called them to have them come repair it as their invoice states they warranty there installation and labour for 10 years. We called multiple time and never received a call back then they sent a subcontractor out to assess and fix our roof instead of holding to there warranty. The subcontractor repairing the roof found that the old shingles had not been removed, the metal valley had been installed wrong and the ice shield was improperly installed. I would not recommend this company to anyone.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 3 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 3, of which 3 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Cornwall Siding Ltd. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
