At Armadas Exterior LLC, we are certified manufacturers for the top two roofing producers in the United States: GAF and Owens Corning. Both companies have led the industry for over 100 years. They maintain elite certification standards. Both manufacturers selected us to install their premium architectural products with an enhanced warranty.
We deliver certified excellence directly to homeowners across Oregon. We serve the Portland Metro area (including Damascus) and our southern location in Cottage Grove, which covers Eugene and Springfield.
What Does Manufacturer Certification Mean for You?
As certified roofers, our entire team receives direct training from the manufacturers. This includes our installers, inspectors, office staff, and estimators. We complete training multiple times each year to maintain our credentials. This ongoing education keeps us up to date on new products and installation procedures.
Why Choose a Certified Roofer in Oregon?
Certified contractors install your roof according to strict engineering standards. This compliance qualifies your home for premium extended material and workmanship warranties. Non-certified crews cannot offer these structural protections. Without them, installation errors can leave you paying for leaks out-of-pocket.
A certified installation protects your long-term financial investment. If you are planning your exterior budget, review our breakdown on How Much Does a New Roof Cost? to calculate your estimated cost per square foot.

Theses manufacturer’s spend millions of dollars every year on research and development to improve their products and remain number one in the industry. It is up to the company that installs the roof to do it properly and to the manufacturer’s expectations. Have you ever heard the phrase “I have been roofing for 20 years and I am the best at what I do!”? Perhaps not but I imagine you have heard, “You can’t teach an old dog new tricks”. Is it safe to assume that these roofers are perhaps unwilling to accept that there might be new and improved methods, new and better technology? Technology changes as do products and procedures, it our commitment to remain ready to evolve with the industry.
Before you have made your commitment to the contractor that will be installing your roof or any product for that matter, you should consider their qualifications and credentials. Make sure that you are selecting the right contractor for the project you are working on and that their skills match their confidence. “I have been roofing for over 20 years” should not be the deciding factor. For all we know that contractor could be roofing wrong for over 20 years or perhaps just for the last 5 years when the local city, county, or state codes may have changed.

pgraded Products Require Modern Training
Top manufacturers spend millions on research and development every year. They constantly improve their products to lead the industry. However, the installation crew must apply those products correctly.
Some roofers rely solely on years of experience, but industry techniques evolve. Construction technology changes, building codes update, and installation procedures improve. Our team commits to learning and evolving alongside these industry advances.
Selecting the Right Credentials for Your Project
Before hiring a contractor, verify their qualifications. “I have been roofing for 20 years” should not be your primary deciding factor. An uncertified contractor might use outdated methods or miss recent city, county, and state code changes.
Building standards change over time. For example, companies once used asbestos in roofing and lead in paint. As safety technology improved, regulations adapted. We adapt our methods to match the latest industry safety and performance standards.
