Top Choice Roofing Company in Windsor
SAWDAC Accreditation Badge


We are certified with several major manufacturers.

To be certified, contractors have to be adequately insured, have a proven reputation and be committed to ongoing professional training. We take this a step further and even have our own in-house training, where we’ve developed specialized company specific, time-tested, installation techniques.

We are active in CARE (Center for the Advancement of Roofing Excellence), with our status as a GAF Master Elite Contractor which is known to be the most difficult roofing certification to achieve.

Manufacturer certification enables us to offer you enhanced warranty coverage, not available from non-certified contractors. Feel free to view our certifications below. You can also view our awards on a separate page.


Insurance and WSIB Coverage

We have more than just the adequate insurance required by our manufacturers certification programs, in addition to our WSIB coverage and we don’t just tell you we have this, we prove it! You can view this information below as well. Due to the expense involved, many contractors have decided not to carry proper insurance or workers compensation and this puts you, the customer, at risk and potentially accountable. Don’t take chances with your home or your family; before you hire a contractor ask to see a valid insurance certificate and a WSIB clearance certificate.
