Metal is one of the best roofing materials to install on a home in Florida. This material offers some of the highest resistance to damage caused by hurricanes and tropical storms. However, you must choose from multiple types of metal roofing before re-roofing or building a new home.
Corrugated sheets are the original metal roofing material, but they are no longer the only option. Choose between classic corrugated panels and newer standing seam roofing by considering the benefits of each type.
When it comes to the cost of roofing materials alone, corrugated metal is less expensive than standing seam panels. You can find corrugated panels for as little as $3.50 per square foot, while standing seam options start around $8 per square foot.
The least expensive corrugated panels tend to lack a coating, so you will need to factor in the cost of immediately painting or coating the roof as part of the installation price. Most standing seam roofing products feature long-lasting coatings to reduce the need for future painting or coating, while corrugated roofing needs regular recoating to stay in good condition.
One reason that corrugated metal roofing products tend to cost less than standing seam panels is that they use thinner metal. Unfortunately, thinner metal roofing tends to wear out faster than thicker sheets of metal, especially if rust or corrosion sets in due to a lapse in recoating.
Thinner metal is also more prone to bending in high winds, making it less than ideal for use in areas with hurricanes and other storms. For a roof you can trust to handle the harshest weather, stick to standing seam roofing or the thickest corrugated metal you can find.
Unlike asphalt and wood shake shingles, metal doesn't just wear out over time from sun and rain exposure. These weathering effects do eventually wear away the protective surface coating, but what really damages the metal is the resulting corrosion.
Since standing seam panels are thicker and tougher, they also offer a longer lifespan and greater durability. Many standing seam roofs also feature a hidden fastener design that keeps all of the necessary screws hidden under a layer of roofing. Hidden fastener roofing is much more leak-resistant since water has to penetrate at least one layer of metal before moisture can reach a fastener.
Standing seam roofing also better resists corrosion due to the carefully folded design of the seams. Raising the seams up above the rest of the roofing prevents water from gathering and starting a rust problem that eventually leads to leaks. Corrugated metal sheds water better than a flat surface but not quite as well as standing seam roofing.
Both corrugated and standing seam roofing require some of the least maintenance of all roofing materials. Both only need occasional cleaning to keep branches and leaves from trapping moisture and starting the corrosion cycle. You may also need to recoat the roof every decade.
If you choose corrugated metal, you'll need to stay on top of recoating every time the surface fades or starts to crack since the thinner metal will develop leaks quickly once the original coating is compromised. Since standing seam metal is generally thicker, you can wait a little longer between coatings without having to worry about holes developing through the panels.
