10 Signs That Your Roof Needs Replacement or Repair

Green signifies a number of things. In the fairytale/fantasy world, it would represent a cottage deep within a tranquil forest, far away from evils clutches.

Once that green moss blanket forms and covers a section of your roof, you know that your house is in trouble.

Can I Use A Pressure Washer On A Metal Roof

The absolute very LAST technique you want to use on your metal roof is the strictly high pressure washing method with a high pressure tip and damaging pressure washer. A metal roof is very strong against many earthly elements but highly pressurized water or high pressurize anything is not recommended! In fact, pressure will not even do anything for you as far as cleaning the roof is concerned. A metal roof is constructed seamlessly or with screws and those screws have a rubber gasket and the high-end screws have a metal cap over the gasket for extra protection. Pressure Washing can damage these screws and expose the weak areas of your roof causing roof leaks in your metal. High pressure can also damage the finish on the roof as all roofs are made of different qualities, metal compositions, and more variables. The optimal amount of pressure you want to use when washing a roof is around 100-300 PSI and preferably HIGH-FLOW & LOW-PRESSURE. We consider HIGH-FLOW approximately 8 gallons per minute of water flow or greater.

Why Is There So Much Moss On My Roof

Moss thrives in cool, damp environments, and most of its spores tend to be produced during the spring and fall seasons. If there are parts of your roof that dont get much direct sunlight throughout the day, then they can be more susceptible to outbreaks of moss. The longer it is able to exist, the more it will grow across your roof and even between and under the shingles. Its best to have a roofing professional inspect it to see whether you need to replace your roof altogether or just remove the moss and make any necessary repairs.

How To Prevent Moss From Growing On Your Roof

The best way to prevent moss from growing on your roof is to minimize its ideal growing environment.

  • Limit shade and clear any debris that could lead to moisture on your roof.
  • Consider trimming tree branches to expose your roof to more direct sunlight.
  • Keep your gutters clean and remove fallen branches and debris.
  • Check your downspouts and make sure they are properly draining a safe distance from your house.

Houses with multi-level roofs are at a higher risk of moss because the gutters on the upper roof often leak onto the lower roof, creating a perfect home for moss.

You can also prevent moss growth by installing zinc or copper coating strips below the top ridge on both sides of your roof.

Zinc and copper are both very toxic to moss. As water comes into contact with these strips and runs down your roof, it takes the zinc or copper with it.

Nowadays, you can install a zinc or copper roof that naturally prevents moss. This type of roof is very rare, though.

Steel roofs cost twice as much as asphalt shingles roofs. Roofs made out of zinc or copper cost two to four times as much as steel.

If you happen to be in the market for a new roof and have a massive budget, ask your roofer about zinc/copper.

Will Laundry Detergent Kill Roof Moss

Do not put Tide or any other laundry detergent on your roof. Laundry detergent is a de-greaser. It loosens the tar and pulls oils out of the shingles, causing the loss of granules. Despite what some articles claim, avoid using laundry detergent. There are so many other formulas to use, like vinegar, bleach, and solutions specifically made for killing moss, why risk it?

Moss Causes Mold Growth

Theres nothing more troublesome than having a rooftop infested with mold. Unfortunately, moss is often accompanied by mold, which can quickly spread to your walls and other areas of your home. Mold is often invisible, going unseen and unsmelled for months before you realize there is an issue.

The issues outlined above are just the start of the problems that a mossy rooftop entails. What if you have to climb up onto the roof to patch a leak? Mossy rooves are wet and slippery, putting you or your roofers at a greater risk for falls and injuries. If you know that your rooftop is prone to moss growth, then you should have a professional roofer inspect and remove moss as needed. Perform frequent visual inspections on your own to determine how frequently to remove the moss from your roof.

Is Lichens On A Roof As Much Of A Problem As Moss

Because lichens growing on a roof surface does not have as much thickness of body as moss, it will hold less water on the roof surface and is less of a wear factor than moss.

Therefore if we have only lichens growing on a roof surface we would be less quick to try to clean it off since lichens not only has a tighter “grip” on the roof surface but the cleaning process for lichens risks doing more harm than good to the roof surface.

At ALGAE, FUNGUS, LICHENS, MOSS COMPARED we show photographs of lichens damage to asphalt shingle roofs.

Fortunately, there are a variety of cleaning solutions that can get the job done. Use a cleanser of your choice during the next cloudy day .

Popular cleansers include Moss B Ware, Bayer 2-in-1 Moss and Algae Killer, and Wet & Forget.

If youd prefer to make your own cleaning solution, you can use any of these three recipes:

  • 2 gallons of water + 1.5 to 3.5 cups white distilled vinegar
  • 2 gallons of water + 1.5 to 3.5 cups chlorine bleach
  • 2 gallons of water + 8 ounces Dawn Ultra dish soap

Remember to wear rubber gloves throughout this process to help avoid exposing your skin to the bleach.

Treat And Protect Against Roof Moss

The best time to treat roof moss is when it’s actively growing. Moss grows very little in summer, but it kicks into high gear during fall rains, moderate winters and early spring months. Treating right before peak fall rains is perfect timing for roof moss treatments. You’ll get the best results if moss is damp, but no rain is forecast for a few days.

If possible, remove excess moss with a rake or broom first. The upper layers of thick moss protect the bottom layer against moss killers. For pitched roofs that you can safely walk, sprinkle dry formulas along the roof ridge. Rains will wash the product down and cover the lower areas for you. For flat roofs or roofs that aren’t safe to walk on, use a liquid formula and a pump-style sprayer to cover all the roof surfaces easily.

As moss dies, rains will wash dead moss away. You can speed the process with a broom or rake, too. To be proactive in moss control, treat your roof right before the rainy season each year. Always keep roofs and gutter free from leaves and other debris that can hold moisture in and promote moss growth.

Keeping roofs free from moss helps avoid costly home repairs.

By taking action to kill existing roof moss and prevent its return, you can protect your family and your investment in your home. CORRY’S Moss B Ware and Lilly Miller Moss Out! products help you take control of roof moss, enhance your home’s appeal and put an end to roof moss damage and costly repairs.

Prevent Future Moss Growth By Installing Zinc Or Copper On The Roof

Prevent a moss problem from returning by adding strips of galvanized or copper-clad sheet metal directly under the top ridge on either side of the roof. Copper is more toxic to moss and algae, but zinc is much cheaper. You can buy sheet metal in rolls and cut into strips from 2 to 10 cm. Secure the strips to the roof with roofing felt nails or screws with rubber washers.

You should also consider pruning any branches that protrude above the roof natural sunlight is an effective way of preventing moss.

Plan Ahead For Safety

Before you start, find someone who can help you with things like moving the ladder and cleaning equipment or bringing things to you. Having a helper reduces the risk of accidents. Have all your equipment and cleaning products ready before you start work.

To prevent falls, wear sturdy, non-slip shoes and, when possible, use a safety harness and rope tied to a tree or other sturdy object. Wear safety goggles to keep spray out of your eyes.
