How to Paint a Metal Roof

Follow these steps to paint a metal roof:

  1. Check the weather forecast for a dry day.

  2. Remove old, loose paint with a paint scraper or putty knife.

  3. Clean the roof with a pressure washer. Wait until the surface is dry before priming.

  4. Apply a coat of primer with a roller. Wait at least one hour for the primer to dry.

  5. Apply the first coat of paint with a roller or sprayer. Wait at least one hour for the first coat to dry, then apply a second coat.

Power Washing a Metal Roof

Power washing costs $0.35 to $0.77 per square foot if you hire a professional. Renting a power washer costs $70 to $100 per day.

The roof must be cleaned before any paint or sealer is applied because dust, grime, and old flaking paint will prevent the new paint from adhering properly.

Sealing and Painting a Metal Roof

Metal Roof Seal

Metal roof sealing costs $0.50 to $4.00 per square foot, depending on how steep and rusted the roof is. Sealing ensures the new paint adheres to the metal instead of peeling off. Roof sealing primer costs $140 to $180 per 5-gallon bucket to cover 1,000 square feet. Home Depot, Lowe's, and other hardware stores sell primer.

Metal Roof Paint

Metal roof paint costs $360 to $480 for 12 gallons to cover a 1,200 square foot metal roof. Use energy-efficient elastomeric paint to reflect heat and reduce energy bills. Elastomeric paint also reduces corrosion, increasing the roof's lifespan.

Bidger Steel, a company that offers high-quality metal roofing and siding products, sells the following types of paint:

  • SMP – Silicon modified polyester paint is popular in the home roofing sector because it can be used on a variety of metals, is effective at resisting abrasions, and does not crack.

  • PVDF – Premium polyvinylidene fluoride is aimed more at the commercial market. Its colors stay true because it is designed to withstand hard conditions like atmospheric pollution and UV rays from the sun.

Metal Roof Warranty

Paint warranty – Metal roof paint comes with a 20- to 40-year warranty that covers cracking, flaking, peeling, or loss of adhesion, providing the paint was applied properly.

Confirm your warranty's details, as some warranties guarantee only the adhesion while others only guarantee the color fade.
