What Paint To Use On Tin Roof

Not Waiting For The Paint To Dry

How to prep for painting a tin roof

As weve previously mentioned, its important to add a few coats of paint to your roof. People often dont wait for the first coat to dry before adding the second coat which is a big mistake.

Make certain that the first coating of paint is dry before you go ahead and paint on the second coating. It should take roughly about an hour or so for it to dry.

Costs Of Hiring Professionals

When budgeting for roof painting, prepare to spend around $2,000 for an average-sized roof. The price will depend on the square footage of the roof and your location. Larger homes will cost more to paint, especially if you have more than one roof to cover!

Professionals will clean the roof before painting and will use commercial-grade equipment that can provide great results. Using a professional company will also ensure that the primer and sealant are correctly applied so you wont have to worry about rusting!

You also might want to first get an inspection before professional painting. An inspection can cost anywhere between $120-$250, depending on where you live. Put together a budget before hiring professionals to paint your metal roof.

How Is A Metal Roof Retrofit System Installed

Typically, this system is installed over a structural metal roof system and the existing roof system becomes the metal cladding for the new roof system.

Another great thing about this paint is that by just using 1 gallon of it, you will be able to cover 50 to 70 square feet of space. But this only applies for situations when you apply a single coating.

It is recommended that you apply two layers of coatings to obtain maximum protection. Lastly, it provides a rubber membrane-like texture on the rooftop, protecting it from scratches and all harm.

How To Prepare A Corrugated Roof For Painting


For a smooth application, you need to ensure the roof space is correctly prepped and ready. The very first step to this is:

  • Cleaning
  • Before applying any paint, you must give your roof a thorough clean, removing all possible traces of grime, grease, oil, rust, debris and dirt-build up. For this, you can simply use a brush and mild cleaning agent. Mix 1 tablespoon of dish soap with 1 gallon of water in a bucket to create a soap solution. Then, hose down the roof surface with clean water and dip a brush or rag into the solution and begin scrubbing. Remove the dirt, then rinse the metal using the hose once again once finished.

    Alternatively, you could also use a high pressure power washer, then use a brush to finish off any tough areas.

    Mould & Mildew

    To tackle areas of mould and mildew, use a wire brush with a solution of chlorinated bleach and warm water. Always remember to wear adequate protective gear such as a breathing mask and gloves when working with bleach. Carefully read manufacturers instructions and research the products you are using to ensure they are safe for purpose.


    Rust is not uncommon on metal roofing. You can easily remove surface rust by scrubbing with a wire brush and sanding with 80 grit dry or wet sandpaper. Any leftover rust can be neutralised by coating the section in a rust inhibitor.

  • Degreaser
  • If your roof is less than a year old, first treating with a metal degreaser will help the paint bond better to the surface for a higher-quality finish.

    Can You Paint A Metal Roof

    Best Paint For Corrugated Metal Roof Uk 2021

    Yes, you can! As long as you prepare the surface of your roof correctly, choose the right primers, paints and sealants, and apply your products correctly, painting your metal roof can extend its life and help make your home more energy efficient.

    Newly installed metal roofs should be allowed to weather for at least 6 months before you apply paint. Since there are a wide variety of metal roof colors available, you probably wont need to paint your roof within 6 months of installation anyway. If you want to paint a new metal roof, though, you can prepare it by washing with a weak acid to remove oils and residue first.

    Whether your roof has been painted previously or not, powerwash just before you start painting. This step removes mildew, dirt, and any loose bits of old paint that can cause adhesion problems.

    If you dont have a power washer or prefer not to use one, the alternative is to use a paint scraper and scrub your roof with a solution of water and trisodium phosphate. Its slower and takes more effort, but it works.

    The more layers of paint, the less likely its going to be worth it, financially, over replacing it altogether. You dont want to go into this project with a half-baked cleanup plan that just involves scraping and sanding as much as you can before adding a new coat of paint.

    If your roof just has one previous coat of oil-based paint, then you should be able to get most of it removed through some hard work, provided you have the proper tools.

    If theres a lot of rusty areas, this could really compromise your new coat of paint, so err on the side of caution.

    As for other types of metal paints, acrylic paints take more time to remove, but otherwise apply the same rules as the above instructions.

    Asphalt coatings are trouble, and it is often not worth the investment of buying special metal paint due to the simple fact that old paint will never come off completely.

    When applying the paint, you will need specialty brushes or rollers. Use a roller designed for corrugated panels and a regular paint roller for standing seam panels.
