Workmanship Warranty

Workmanship Warranties protect consumers from mistakes made during the installation process. When you buy roofing or siding from a professional contractor, you expect the job will be done correctly. At Dayus Roofing we offer multiple levels of workmanship warranties to suit your needs.

The RCAC (Roofing Contractors Association of Canada) recommends that all roofing contractors offer a 2 year workmanship warranty on services provided. This has been the standard at Dayus Roofing over our 94 year history. However, many contractors (similar to what happened with shingle manufacturers warranties) began to offer inflated workmanship warranties as a competitive advantage.

25 Years! The longest and most extensive coverage on the market today!

Today, as a GAF Master Elite Certified Contractor, Dayus Roofing is proud to offer a 25 year workmanship guarantee on select roof installations. This is the longest and most extensive workmanship coverage you can find on the market today and it’s no coincidence that it’s backed by the longest standing roofing contractor in Windsor and Essex County. All 25 year registered workmanship warranties are inspected and certified by a third party to give you maximum peace of mind.

The key with any workmanship warranty is that they are only as strong as the history and structure of the contractor who offers them. It is the job of a salesman to earn your business, but it is the responsibility of the consumer to make sure promises are not empty. Many competitors offer warranties on their workmanship for longer than they have been in business and are nowhere to be found when problems do arise.

At Dayus Roofing, our future is as reliable as our past. As Windsor and Essex County’s oldest roofing contractor we assure you only the best service for your roofing and siding needs. The relationship between our customers does not end after the job is done. Our company structure ensures you are protected for the lifetime of your roof and siding. A 94 year history provides our customers with the peace of mind that we will be here to service any and all Dayus Roofs, even our premium rubber roofs, to the end of their life expectancy.

If you have questions about the details of our workmanship warranty or about the existing coverage remaining on your Dayus Roof or Siding please contact us.
