How long does a roofer need to learn the craft of roofing? Consider the climate of Des Moines; a good roofer needs to experience all seasons, all kinds of weather which tax and tear apart roofs. Would two years be enough? Five? How does experience shape the way a roofing contractor works?


You do not want your house to be the experiment. You want the roofing contractor who installs a shingle, composite, or metal roof to have done such installations before. Roofing is never a “by the book” job. Every home offers its own challenges, from chimneys needing flashing to multiple ridges and valleys.

Select a roofing contractor who can point with pride to other jobs similar to yours. Consider the kind of roof projects your house may need:

  • Steep, low/flat, or varied slopes
  • Gutters
  • Multiple gables
  • Soffits and flashing

Make sure your roofer can prove experience with the same kind of roof, using the same materials you select.


Contractors acquire certifications not just from state licensing boards and the Better Business Bureau, but from manufacturers as well. The more certifications a roofing contractor has the wider that company’s experience. You can see the quality built into a new roof when you see certifications from the manufacturer of your roofing materials.

Certifications are not handed out like mailbox flyers. The manufacturer of a roofing product allows only some installers to offer the highest level of warranties, as a way to protect both product and customer. For example, Owens Corning does its own background check on each roofing contractor. If a contractor has already proven they do quality work and then passes an actual test, that roofer earns the Owens Corning Platinum Preferred Contractor certification.


A good roofing contractor stays busy all year long. In the Des Moines area, weather may cut down on winter roofing work, but talented roofers can also install siding, windows and doors, and complete other year-round projects.

The years roll by and every year is an opportunity for the company to improve, to forge better customer relationships, to get more training. Quality of workmanship and service is more important to them than longevity.

It takes real focus for a roofing company to stay in business for a decade. To stick around through the ups and downs of changing economies for two decades takes grit and hard work.

Look for a company that has proven its worth through at least twenty years; you know those roofers have earned your trust to do right by your roof.
