Metal roofs are becoming increasingly popular due to their durability, longevity, and aesthetic appeal. But how do you know if a metal roof is right for you, especially in Portland, Oregon? Here's a bit of basic info to know and a few pros and cons of metal roofs to help you decide.
The ancient Egyptians and Romans built the first metal roofs out of copper. People in the U.S. began using metal for roofing in the early 1800s. Metal roofs can be custom-made to fit any home, and they come in various colors, styles, and materials, most commonly steel, copper, and aluminum.
Steel: Steel roofs are the most common type of metal roof. They are strong, durable, and energy-efficient.
Copper: Copper roofs are a more expensive option but are durable and long-lasting.
Aluminum: Aluminum roofs are lightweight and easy to install. They are not as durable as steel or copper roofs, but they are still a good option for homes in areas with mild weather conditions.
Pros of Metal Roofs
Durability
Metal roofs are incredibly durable and can last decades, even in the damp climate of Portland. They are resistant to wind, hail, fire, snow, rot, mold, mildew, moss, and algae growth and can even withstand the weight of ice dams.
Wind Resistance
Portland can experience strong winds, especially during winter storms. Metal roofs are designed to be structurally sound and can withstand high winds. They are typically installed with fastening techniques to ensure they remain secure during storms.
Energy Efficiency
Although Portland is known for its mild climate, summers can get warm, and energy efficiency is still important. Metal roofs reflect heat away from your home in the summer and help keep your home warm in the winter, saving you money on heating and cooling bills.
Increased Home Values
The value a metal roof adds to a home will vary depending on several factors, such as the type of metal roof installed. However, a metal roof can be a wise investment for homeowners looking to increase their home's value, especially when prepping to sell the house. Prospective home buyers won't need to worry about replacing the roof for a long time. That peace of mind adds value for them; plus, they won't be looking for discounts from the purchase price due to roof issues.
Sustainable Choice
Today's metal roofs are made from recycled materials and are recyclable, making them a sustainable choice.
Low Maintenance
Portland experiences a significant amount of rainfall throughout the year. Metal roofs are excellent at shedding rainwater quickly, preventing water accumulation and minimizing the risk of leaks. They have a tight interlocking design that helps channel water away from the roof.
By design, metal roofs are virtually maintenance-free. They do not require shingling or painting and are not susceptible to mold or mildew.
Longevity
Metal roofs have a long lifespan, often 40 to 70 years or more, compared to composition shingle roofs and wood shake roofs lifespan of 10-20 years. This can be particularly beneficial in Portland, where roofs may be exposed to moisture and frequent rain. A durable metal roof can provide long-term protection for your home.
Curb Appeal
Metal roofs come in various styles and colors, allowing you to choose an option that matches the architectural style of your home. Whether you prefer a traditional or modern look, there are metal roof options to suit your taste.
Cons of Metal Roofs
While metal roofs have numerous advantages, it's also important to take a look at some potential drawbacks. Here are a few cons associated with metal roofs:
Higher Upfront Cost
Metal roofs tend to have a higher initial cost than other roofing materials like composition shingles. The cost of the metal itself, along with the specialized installation techniques required, can contribute to the higher upfront investment. However, it's important to consider the long-term benefits and durability of metal roofs because the cost is offset by lower long-term costs of maintenance and repairs.
Noise
Metal roofs can be noisier during heavy rain, hailstorms, or other weather events than roofs made from asphalt or wood. However, the sound can be dampened by proper insulation and underlayment during installation. Many metal roofs are installed over solid sheathing and insulation materials that help reduce noise.
Dents
While metal roofs are generally durable, certain types of metal, such as aluminum, may be prone to denting under extreme weather conditions like large hailstones or falling tree branches. However, this can be mitigated by selecting thicker metal gauges or choosing more impact-resistant metal options. Fortunately, dents can usually be repaired without replacing the entire roof.
Expansion and Contraction
Metal roofs can expand and contract with temperature changes. Over time, this can cause fasteners to loosen, potentially leading to leaks if not properly maintained. It's important to use appropriate fastening methods and materials during installation to allow for the natural movement of the metal.
Maintenance and Repairs
While metal roofs are generally low maintenance, occasional inspections, and maintenance may be required. This can include checking for loose fasteners, inspecting seals around vents and flashing, and ensuring the roof is debris-free. If repairs are needed, finding matching replacement panels or shingles may be challenging if the specific style or color is discontinued.
Scratching and Fading
Depending on the type of metal and coating used, metal roofs may be prone to scratching or fading over time. This is more common with softer metals like aluminum. However, many metal roofs come with protective coatings or finishes to enhance their durability and resistance to fading.
It's important to note that some of these cons can be mitigated or minimized through proper installation techniques, regular maintenance, and selecting high-quality materials. If you are considering a new roof, metal roofs should be at the top of your list. While they may be more expensive upfront, the long-term savings will make them worth the investment. Also, it's good to check with homeowner association guidelines (if applicable) and local building codes in case of any restrictions.
