Can I Paint My Metal Roof?
Homeowners with traditional shingle or tile roofs are pretty much stuck with whatever color or shade those roofs are until it’s time for the next roof. One of the many great things about having a metal roof is, if you don’t like the color, you can re-paint it – as long as you do it right.
Tips for painting a metal roof
If your roof is brand new, give it about six months to weather before putting on paint. When it’s time to paint, here’s what you need to know.
Prepping a metal roof
Paint adheres best to surfaces that are completely clean, smooth and dry. As a first step, you can clean your metal roof with vinegar diluted in water to remove any residue or oils.
Just prior to painting, power wash the roof. This will get rid of any new dirt, mildew and paint chips. You can forego power washing by using a scraper and sandpaper to clean and smooth out the roof’s surface.
The best paint
First, make sure to buy paint that’s specifically designed for metal roofs. For both unpainted and painted roofs, acrylic latex is a good paint choice. You also can use oil-based paint. Whatever paint you choose, start with a coat of high-quality primer designed for metal surfaces. Don’t scrimp on the cost of either the paint or the primer – your finished result will show it if you do.
You can find special paints for metal that include ingredients that resist water and fire and repel small animals and insects. When shopping for paint, ask about types that will keep your home cooler by reflecting the sun’s UV rays. A lot of different mixtures of paint are available today for metal roofs that bring specific benefits, so shop well and buy a paint that best suits your needs.
Applying the paint
Preparation and paint-selection are the critical jobs in painting a metal roof. Applying the paint is fairly straightforward.
You basically have two choices, like with most other painting projects: roller and brush, or sprayer. If you choose to do it by hand, buy rollers and brushes made to be used on corrugated metal and take your time. Painting by hand is a labor of love, and there’s no reason to rush it.
An airless sprayer will make quicker work of your paint job and is particularly recommended if your roof has steep pitches. With a sprayer, you can use extension arms to get to areas that might be dangerous or difficult to get to with a roller or brush.
The drawback to sprayers is you can’t spray in the wind. If you use a sprayer on a windy day, not only will you likely paint other parts of your home and property, you probably will be getting a visit from irate neighbors for doing a free paint hazing on stuff whose original color they preferred.
Finally, if you don’t like either of these painting methods, contract with a professional painter, who has the tools and expertise to do a fantastic job.
A twice-a-year cleaning with mild detergent should be all you need to keep your newly painted metal roof looking great for years.
