Best way to paint a metal roof.

This is why when you are considering painting your metal roofing it makes sense to go for specific paints for the metal roof. If you re not sure what kind of roof you have ask a professional roofer to inspect it before you paint it. You cannot set up roof jacks on a metal roof as you can on a shingled one so if you plan to paint with a brush or roller include a safe way to reach the ridge in your plans. The type of paint you should use for the topcoat on your metal roof will depend on the weather conditions and roof position.

If you are preparing to paint a rusted galvanized metal roof pay special attention to surface preparation or you will have a recurrence of rust and or flaking. Sand the entire metal roof surface very lightly with your wire brush or sandpaper. Terne metal roofs are extremely long lasting but because they look very similar to galvanized metal a person can unknowingly invite problems if they use the wrong paint. Galvanized metal roofs are coated with a layer of zinc that inhibits rust.

Another mistake is to forget or ignore using a sealant before the application of the metal paint. A roof that will be often exposed to direct sunlight will perform best with a different paint composition than one in a damp shaded area. Water resistant metal roofing paint for example can be of great value if you live in a rainy area. Not using a sealant.

To make the optimum choice for your roof consult a paint specialist. Try to achieve a slightly abraded texturized finish as this helps your new paint bond with the roof finish. Galvanized roofs require the use of a different paint than what is used on terne metal. If painting light to moderately used indoor metal surfaces think wall sconces bed frames or guest room night tables go with water based acrylic paint a cheaper 15 to 40 per gallon.

To paint a metal roof you ll need to use an oil based paint if you have a terne metal roof or an acrylic based paint if you have a galvanized metal roof. You ll also need to purchase a primer designed for metal roofs. One of my neighbors used an oil based.
