Re-roofing large centre section of house replacing original tiles dating at least from1950-ish and quite possibly from the date the house was originally built - 1929. Rosam proved to be easily the most impressive contractor we have ever employed and we have been in this house since 1979. Engaging, friendly, faultlessly polite, and refreshingly open to discussion and explanation regarding materials, techniques, etc. The moment we pointed out some visual aspects we did not like they corrected them to our taste with no delay nor objection - as we have sometimes experienced in the past with other teams. Thoroughly impressed with their expertise, competence and fine quality workmanship. Very highly recommended indeed.
