How to find a reliable roofer in my area?

Always do your homework first. There are several trustworthy online resources with client endorsements and reputable trade organizations where you can research policies and best practices.

The next step is to request a quote from local roofing companies and designate a deadline. Each quote should include the following:

  • A thorough explanation of the task that has to be done.
  • Cost estimates for labour and supplies.
  • Plans and transparency for unforeseen work that may occur during the project.

Lastly, verify accreditations and any online reviews to complete your research. Never base a decision on a quoted price alone. Additionally, you can look into any complaints or charges by searching the Better Business Bureau and the Consumer Beware List.

How long should a roof last?

It depends on the age, roofing material, and regular roof maintenance. According to the type of roof, these are our suggestions:

  • Asphalt shingles: up to 30+ years
  • Rubber roofs: up to 20 + years
  • Metal roofs: up to 50 years
  • Tile and concrete roofs: up to 75+ years

Before your roof’s life span expires, we recommend replacing it within it’s last three to five years.
