Stainless steel and copper chimney caps perform best in Rhode Island’s coastal climate. Stainless steel offers excellent corrosion resistance at an affordable price point, making it our most popular choice for Rumford homeowners. Copper caps cost more upfront but develop a protective patina over time and can last 50+ years with minimal maintenance. Both materials handle our freeze-thaw cycles, salt air, and heavy precipitation better than galvanized steel or aluminum options. We help you choose based on your budget, home style, and long-term plans.
