Common Metal Roofing FAQs
Will metal roofing rust or corrode?
Metal roofs get coated with protective paints and enamels designed to prevent rust and corrosion. Regular maintenance (i.e., once per year) can help extend the protection of these coatings. Certain chemicals – fertilizers, animal waste, acid rain – can damage metal roofing over time. Pine needles left to decompose can also cause damage to metal roofs because of its acidic nature.
The good news is that it’s easy to maintain a metal roof. Just spray it down with fresh water using a garden hose or low-pressure power washer to remove harmful chemicals, pine needles and other debris.
What metals are used to make metal roofing?
Various metals are used in manufacturing metal roofing systems and a combination of metals may also be used in some cases. The most common metals include aluminum, steel and copper.
Aluminum is lightweight and an ideal choice if you live near the ocean (seawater can cause damage to some metals). Steel is another popular choice for metal roofing.
