Whether you are replacing a damaged roof or installing a roof on your new home, choosing the right material for your roof is essential. Choosing the right material will determine how long your investment will last. Metal roofs, for instance, are effective due to their durability, energy efficiency and require low maintenance. There are different materials used in metal roofing, including zinc, copper, aluminum, tin, and stainless steel. With various colors and styles to choose from, metal roofing products allow you to customize the look of your home.
Most metal roofs come with a warranty of 40 years, with some metal roofs lasting longer than 60 years. Other metal roofs outlive their contract, such as standing seam metal roofs which have a warranty of 30 years. With regular maintenance, you can also stretch the longevity of your metal roof. In this article, we will highlight the factors affecting the lifespan of metal roofs and the advantages and disadvantages of metal roofing.
Factors affecting the lifespan of a metal roof
The installation process can have a significant impact on the longevity of your metal roof. A well-installed metal roof is likely to last longer than that which is poorly installed. You can install a metal roof with a painted finish, which protects the metal from exposure to air, moisture, or due. These elements can cause rusting to a metal roof that has been damaged or scratched while being installed. To avoid this, ensure that you hire competent experts to perform the installation.
2. Climatic conditions
Extreme weather conditions cause wear and tear on your roof, causing it to last for a shorter period than expected. For instance, a place that experiences a lot of hail and snow weakens the finish and integrity of the metal roof panel. High temperatures can also affect the lifespan of your metal roof, more so if you have installed a screw-down metal roof since its expansion capability will be limited. Since you cannot control the local weather, consider installing a type of metal roof that can withstand the climatic conditions in your area.
Proper maintenance of your metal roof will increase its lifespan. Ensure that experts maintain and inspect your metal roof annually to ensure it is in proper condition. Also, make sure to clean out debris and dirt more often. In case you notice any scratches on your metal roof, hire experts to repaint it sooner than later.
Pros of metal roofing
Depending on the material, metal roofs can last 40-70 years compared to traditional asphalt roofing materials that last for about 12-20 years.
2. Are durable
With proper installation, certain roofing materials can sustain wind gusts up to 140 miles per hour. They will also not rust or crack and may be impact-resistant, hence withstand extreme weather conditions like hailstorms. Metal roofs also require low maintenance but should be inspected periodically to check if they require any repairs.
3. Environmentally friendly
Metal roofs are 100% recyclable at the end of their life as a roof. Most shingle tear-off wastes end up as part of the building-related waste stream that amounts to up to 20 billion pounds annually.
During a wildfire or lightning strike, metal roofs will not spark and ignite into flames.
5. Energy efficiency
By reflecting the sun’s light rays that contribute to roof surface radiant heat, metal roofs reduce cooling costs by about 10-25%.
Cons of metal roofs
Compared to other roofing materials, metal roofs are more costly. However, investing in a metal roof is worth the cost, especially if you plan to stay in your home long enough.
During heavy rain or hailstorm, metal roofs may be noisier. To prevent this, you can insulate your attic, which may increase costs.
3. Expansion, contraction, and fasteners
Large panels attached to metal roofing materials are designed to expand and contract when warm and cool. However, exposed and concealed fasteners have different lifespans, while neoprene washers and screws are affected by climatic conditions.
4. Color match inconsistency
In case of repairs or home extension in the future, it may be difficult to find the exact match of the previously used metal.
Poor installation or repair can lead to water accumulation on the metal roof, which may otherwise cause damage. Low-quality metals can also be less durable, while some rusting in certain climatic conditions.
Before installation, ensure that your metal roof product is tested, labelled, and approved by a testing organization. To enjoy a long time service of your roof, choose a metal roofing material!
