Tips For Repainting A Metal Roof


If you have purchased a home that has a beautiful exterior except for an old, faded metal roof, then you might take it upon yourself to paint it. This is helpful because it will improve the way the exterior of your house looks without actually requiring you to get a new roof. Metal roofs tend to last a long time, so repainting is your best option. Here are some tips for repainting your metal roof.

1. Scrape Away Paint That's Coming Off the Roof

The first thing that you need to do is scrape off the paint on your roof. The good thing is that you don't have to scrape off all the paint. You merely have to scrape off the paint that is going to cause any new paint that you add to not adhere as well. Look around the edges first for paint that is peeling or flaking. Once you've scraped off the paint along the edges that is not securely adhered, check the middle to see if there is any flaking. You do not have to remove paint that is securely adhered because it is likely to stay securely adhered once you cover it with another layer of paint, allowing that layer to remain adhered as well.

2. Sand the Roof

Next, take sandpaper and lightly sand the entire roof. Your goal when sanding isn't to get rid of paint but merely to give the entire surface of the roof a textured feel. This is because paint tends to adhere better to textured surfaces rather than smooth surfaces. You should be able to feel a noticeable difference between the parts of the roof that you have already sanded and the underside of the roof near the eaves that has not been sanded.

3. Get Rid of the Dust and Any Other Debris

Finally, take a bucket of warm water and add dish washing detergent to it. Then, dip a clean rag into the bucket and start carefully wiping down the roof. There is no need to scrub unless you encounter bird poop or some other debris that is firmly adhered to the roof. When you are done washing off all of the dirt, take a hose and hose down the roof to get rid of any lasting water. Allow the roof to entirely dry before you start painting it.
