Sealing and Painting Cost

The average cost for painting and sealing a metal roof falls between $1,158 and $3,598. Along with the labor cost to paint a metal roof, you should consider roof paint prices, as well as any primers and sealers. Primers and sealers are an important part of the project, as these will protect your roof against heat, cold, moisture, and snow.

Factors That Determine Metal Roof Painting Cost

Most professional roof painters will charge based on the square footage of the roof. Along with larger roof sizes, roofs steeper than a 6:12 pitch will typically cost more to paint. This is because the roof is not considered walkable and will require greater labor, staging, and safety protocols to paint. For an accurate price estimate, contact a professional roof painting contractor.

Power Washing and Prep Work

The cost to power wash a roof ranges between $0.50 to $1 per square foot. It is costlier than other power washing jobs because it takes more setup time, is harder to reach, and is generally more labor-intensive.

There is also the option of renting the power washing equipment and handling the project yourself, but you should approach this with extreme caution. The average cost to rent a power washer ranges from $35 to $125 per day. However, it's important to note that power washers can easily damage siding, screens, and other components of the building. For the best results, always consult a professional.

Before you paint a metal roof, it's important to thoroughly power wash the entire surface area. This will remove any mold, dirt, dust, and other debris that could interfere with the adherence of the paint to the roof's surface. It will also help remove old, flaked paint and prepare for a smooth application.

Roof Warranty

Most professional painting companies will include a warranty with their metal roof painting cost. This protects you from any defects in the application or premature wear and tear on your newly painted roof.

Be sure to ask about the warranty when reviewing potential painters. This should be a major consideration when comparing costs.

DIY vs. Professional Cost to Paint a Metal Roof

As with many home improvement projects, doing it yourself will considerably reduce your metal roof painting cost. However, due to the risks involved, it is strongly advisable that you hire a local metal roof painting contractor. This ensures the safe, quality, and timely completion of the job.
