Why Oregon homeowners choose Interlock aluminum shingles over traditional roofing

Weather extremes demand superior materials. From Portland's relentless rain to Eastern Oregon's temperature swings and increasing wildfire risks, your roof faces challenges that destroy conventional materials within 15-20 years. Aluminum shingles are engineered to last 50+ years with Oregon's demanding climate in mind.


The hidden costs of repeated roof replacements are staggering. Asphalt shingles require replacement every 15-20 years at $15,000-25,000 each time. Over your home's lifetime, you'll spend $45,000-75,000 on multiple re-roofing projects. Our aluminum shingles eliminate this endless cycle.

Happy to have a greater sense of security about the danger posed by fire 🔥🔥🔥

 ★★★★★

The company was very informative and efficient, and we are happy with both the aesthetic and practical results. We are also happy to have a greater sense of security about the danger posed by fire, which has been a worry because we live in a forested area far from emergency services. The workers were polite and professional and cleaned up the site pretty well. It was expensive, but we're very satisfied with the work.

Understanding your investment in aluminum shingles

Lifetime value that makes financial sense

Traditional roofing creates an endless expense cycle. Asphalt shingles require replacement every 15-20 years, maintenance every 3-5 years, and frequent repairs from weather damage. Over 50 years, homeowners typically spend $60,000-100,000 on roofing.


Aluminum shingles eliminate ongoing costs. With our Never Re-Roof Again warranty, your initial investment covers 50+ years of superior protection: no more replacement projects, minimal maintenance, and substantial energy savings.



Property value enhancement adds immediate equity. According to real estate professionals, premium metal roofing increases home value by $15,000-30,000 while reducing the time on the market when you sell.


Insurance premium reductions provide ongoing savings. Many Oregon insurance companies offer discounts for Class A fire-rated and impact-resistant roofing materials.


Flexible financing options are available.

Investment-grade financing makes premium roofing accessible. We partner with leading home improvement lenders to offer competitive rates and flexible terms that fit your budget.


Energy efficiency incentives may apply through local utility programs. Our team helps identify rebates and tax credits that reduce your net investment.
