4 Common Mistakes When Painting a Metal Roof

Feb 14, 2018

Metal roofs are becoming popular among homeowners because they are durable and demand less maintenance than other types of roof materials. At first glance, painting your metal roof might seem simple, but there are common mistakes that homeowners tend to make when tackling this task.

Here are some of the most common mistakes made in painting metal roofs that will help ensure you will end up doing your paint job perfectly.

1. Not Preparing The Roof Surface

Try to clean the surface from any dirt and grime that would make the process of painting and applying sealants difficult. It is always best to work on a clean and dry roof before coating it.

2. Using Leftover Paint

A metal roof needs a special kind of paint, simply because the roof is made of different material than the rest of the house. Thus, using what is left from a previous painting project will not work on a metal roof. Buy and use proper paint from your local depot store to avoid a runny and unsightly paint job.

3. Not Using Sealant

This step is very important. Homeowners should not miss or ignore using a sealant before applying the metal paint. A sealant will hold the paint in place, making it last much longer. Without it, the metal paint might just peel off with time. Make sure to do your research to find the right sealant for the paint you will be using, as each paint requires a specific sealant.

4. Not Maintaining The Roof After Painting It

Being one of the most important parts of the house, the roof should be regularly cleaned and maintained. It should be swept clean of debris every few weeks. In fact, even after painting a metal roof, it is necessary to wash it down with a mixture of bleach, liquid detergents, and water at least once every six months.
