Tools you Need to Paint Metal Roofs
To make sure your metal roof looks awesome and stays that way for a long time, you must use the right tools. Here’s what you’ll need:
- Brushes: Brushes are great for painting small spots or tricky areas like around vents. Get some good synthetic brushes made for metal roof paint. Choose a size that fits the job, like a smaller brush for tiny areas and a bigger one for larger spots.
- Rollers: Rollers are perfect for covering big parts of your metal roof fast. Look for a sturdy roller that’s about 9 inches wide with a fuzzy part (called the nap) that’s at least half an inch long. Using a roller with a long stick can help you reach high or slanted spots.
- Sprayers: If you’ve got a big roof to paint, sprayers are the way to go. They’re quick and easy. Find a good airless sprayer with a tip that’s around 0.017-0.021 inches wide. Just make sure to follow the instructions carefully for setup, using, and cleaning to keep it working well.
- Safety Gear: Painting a metal roof can be risky, especially if you’re up high or dealing with chemicals. Always wear the right gear, like a safety harness, shoes with good grip, gloves, and safety glasses. If you’re using spray paint or chemicals, think about wearing a mask to protect your lungs.
- Power Washer: Before painting your metal roof, it’s smart to give it a good clean with a power washer. This handy tool shoots water at high pressure, blasting away dirt, old paint, and other stuff.
- Paint Scraper: You can use this tool to gently scrape off any old paint, rust, or dirt that could mess up your new paint job. Be careful not to scrape too hard and damage the metal.
- Primer: Primer is like a base coat that helps the paint stick better and protects the metal from rust. Remember to let the primer dry completely before you start painting to make sure your paint job lasts a long time and looks awesome.
- Paint Tray: If you’re using a paint roller to paint your roof, you’ll need paint trays to hold the paint. Make sure to use a tray that’s big enough for the roller and has enough paint.
Preparation Before Painting your Metal Roofs
Before you start painting your metal roof, there are a few things you should do to get ready.
- Inspection: First, do a thorough inspection of the roof to see if any repairs are needed. Check everything, including the rust or loose parts. Fix any problems you find before painting. Also, check the soffits and fascia to make sure they’re in good condition. It’s good to do this inspection once a year.
- Budget: You need to plan your budget for the project. The size and slope of your roof, how much prep work is needed, the type of paint you choose, and the cost of labor can all affect how much you’ll need to spend.
- Check the Weather: Don’t forget to check the weather forecast. Painting on a rainy day is a bad idea because the paint won’t stick properly. Wait for several dry days in a row, ideally about 10 days, so the paint can dry completely.
- Go with the Sun: Start painting early in the day to give it plenty of time to dry in the sun. That way, your metal roof will look great and stay protected for years to come.
How to Paint your Metal Roof in 5 Steps
- Remove Old Paint: If you don’t remove the old paint, your new paint might not go on smoothly and could start peeling off later. If the old paint is already peeling, painting over it will just make the new paint bubble up, and that’s not what you want. So, use a scraper to gently remove any old paint.
- Clean the Roof: Get rid of dirt, mold, and old paint flakes before you start painting. Use a pressure washer for dirty areas and a wire brush for rough spots. If the paint is coming off, scrape it away completely.
- Check for Mold: If there’s mold on your roof, scrub it off with a wire brush and wash the area with soap and water. Rinse well and let it dry completely. Check again to make sure all the mold is gone.
- Prime the Roof: Before painting, apply a primer to the metal roof. Choose a primer with titanium dioxide for a better finish. Let it dry completely before moving on.
- Paint the Roof: Use a paint roller to apply one or two coats of paint. Make sure to wear non-slip shoes and a harness for safety. It’s a good idea to have another adult nearby in case of an emergency. Follow the manufacturer’s instructions for drying time between coats. One coat is usually enough, but check the instructions to be sure.
