Learn how you can maintain your metal roof.

The finish on quality metal roofing panels will give you many years of trouble-free service.

However, a metal roof is not completely maintenance free. Dirt and pollen can alter the look of the finish. With some simple cleaning, the finish can be restored to its factory look. We have outlined here some things that you can do to protect the look of your metal roof.

Metal roofing is manufactured and installed in a way that will provide you with many years of trouble-free service as long as some simple things are done when needed. Far too often I see roofs that have leaf piles on them or are just plain dirty.

A clean roof is a trouble-free roof. The main purpose of your roof is to shed water off of it during rainy weather. With leaves piled up in the valleys and in other areas, water pools up and moisture becomes entrapped under the leaf pile. That moisture over time can cause damage to the metal roof.

I would recommend blowing off your roof whenever necessary and at least once per year and washing it with a mixture of simple green and water. Other things you will want to check for while on the roof is to check the flashing to make sure it is still watertight and to make sure if you used caulking, that it isn’t cracking or pulling away from the wall. Make sure to check the screws to ensure they are still holding. If you follow these simple steps, your metal roof will be trouble-free.

A few simple steps can ensure that your metal roofing stays looking good. To find out how to take care of your metal roof, click a topic below.

    Metal roof cleaning tactics

    The finish on quality metal roofing panels will give you many years of trouble-free service. However, a metal roof is not completely maintenance free. Dirt and pollen can alter the look of the finish. With some simple cleaning, the finish can be restored to its factory look. We have outlined here some things that you can do to protect the look of your metal roof.

    Remember: Walking on a metal roof can be slippery and extreme caution should be used in order to prevent injuries.

    How to clean your metal roof

    Cleaners you can use:

    • Use one cup of Simple Green®, or other non-toxic biodegradable cleaners, which contain less than 0.5% phosphate, dissolved into two gallons of warm water OR
    • Use one cup of household ammonia dissolved into five gallons of water (room temperature)

    When washing your roof, always start at the bottom and work your way up to the top. You can use a well-soaked cloth, sponge, brush (with soft bristles), or a low pressure washer spray.

    Only used the cleaners and cleaning tools recommended. If not, you can end up damaging the film on the paint.

    If mildew or other fungal growth is a problem and you cannot remove it as discussed earlier, you can mix one cup of household bleach with five gallons of water, along with one cup of mild soap, which aids wetting.

    Once the metal panels have been washed, thoroughly rinse with clean water to eliminate residue. You must remove all residue from the roof or you can damage the film on the metal roofing panels.

    Spring roofing maintenance tips

    Your roof may have survived the winter months, but now it’s time to survey any damage that winter might have caused.

    Spring roof maintenance is a necessary part of increasing the lifespan of your roof – and protecting your home’s precious interior. So, when it’s time to conduct your spring roof inspection, remember these two areas of concern.


    Your roof’s gutter system was designed to remove water from your roof in order to:

    • prevent pooling and moisture buildup,
    • prevent damage to your home’s structure and
    • discourage moisture-related mold growth.

    Dirty gutters that aren’t properly maintained can shorten the life of your roof, so it’s critical that you check them once or twice a year.

    Spring is a great time to inspect your gutters and remove large chunks of debris by hand or with a garden trowel. After manually removing debris, follow with power washing to clean out the remaining dirt buildup.

    Remember, if you have a number of tall trees on your property you may need to check gutters more frequently for stray leaves and twigs.

    After cleaning out your gutters, it’s important to be proactive about trimming tree overhangs and large branches. Use a chainsaw or hand trimmer to clip branches away from the roof, especially if they appear to be dropping debris into your gutters. Finally, check gutters for loose or rusty sections and fix any problem areas as soon as possible.


    Flashing, or the metal strips that seal gaps and prevent water from seeping under shingles, should be checked during each semi-annual roof inspection.

    It’s especially important to inspect flashing around your chimney, skylights, and valley regions. These are the three most common locations for leaks as winter wind and storms can cause flashing to pull away at these areas. Using small roof fasteners, tack down loose flashing and seal tack holes with roof cement. Call your local roofing professionals when you have more serious flashing problems or give us a call if you need a qualified referral.

    In Consultation

    While it’s easy to do simple roof inspections and repairs yourself, it’s advisable to hire an expert if your home has an aging roof, or if your roof is particularly steep and dangerous.

    Fall roof maintenance tips

    Maintaining your roof is the one thing that most homeowners neglect to do to their house. A metal roof will provide you with many years of trouble-free service, but that doesn’t mean you neglect it. Maintaining your roof starts from the minute you put in your last screw. After working on a metal roof, more than likely you will have metal filings on your roof that you can’t see from installing screws and cutting metal pieces. Metal filings should never be left sitting on the roof. What ends up happening is that these metal filings will start to rust and will leave surface rust on the metal roofing panels. Nobody wants to see their new metal roof start rusting before they even get to start enjoying it.

    The other maintenance concern we see quite frequently, especially in the fall, is a neglected buildup of leaves and debris. Initially leaves on a metal roof might seem harmless, but moisture is being trapped between the leaves and the metal which could lead to damaging the metal. And this goes for anything else, not just leaves that can land and collect on your roof. Don’t feel like you have to blow your roof off every time you see a couple of leaves on it, but you should make it a habit to do it a couple of times a year depending on where your house is located in relation to trees. Do this and you are doing your part in extending the life of your metal roof even longer.

    Potential preventable re-roofing hazards

    When you re-roof your house or hire a contractor to do it for you, there are a couple of areas that may create hazards that you should keep an eye out for.


    Ventilation pipes that exit through the roof can sometimes become disconnected when the new roof is applied. Besides making sure that these areas have proper flashing to avoid potential water leaks and subsequent damage, it is important to verify that these vent pipes are re-connected completely when the re-roof is completed.

    If the ventilation pipes are not correctly reconnected, it is possible that harmful gasses could collect in your attic space creating a potential health hazard.

    It is worth pointing out that most inspection authorities are not required to verify that roof vents have been re-connected.

    Punctured gas lines

    If your home has gas-powered appliances such as a hot water heater, furnace, or generator, it is important to verify that the gas lines, which sometimes run through the attic space, have NOT been punctured accidentally by the roofer. Obviously, a punctured gas line can pose a very serious hazard to the house and its occupants if the gas were to collect in the attic space and ignite.

    Sometimes gas lines run in the attic’s low slope areas making the lines difficult to completely inspect. Even if you can trace and inspect the entire line, you can be doubly sure there are no leaks by observing the gas meter. Make sure all your gas powered appliances are not running then check the gas meter. If the meter indicates a flow, it is likely there is a leak and the gas lines should be fully inspected.

    It is important that you verify the integrity of both the roofs vents and gas lines yourself or make sure that your roofing contractor has inspected them.
