Mold On Attic Roof Sheathing

Cleaning mold and mildew from a roof – Krystal Klean

As you can imagine, the labor required to hand scrub every square inch of roof sheathing is quite significant. Additionally, encapsulation is still necessary, as the hand sanding and brushing will not remove the underlying stain left by the mold spores. Dry ice blasting is an attractive, but expensive, choice.

Additional Tips And Advice

  • Do not allow the cleaner to dry on the surface.
  • For additional protection, apply a protectant product designed for the specific material of your convertible once the area is clean.
  • When scrubbing the surface with the cleaner, do not allow it to spread to other surfaces as it may cause damage.
  • Avoid using bleach-based products. Even though it will remove the mold, the stitching in the convertible top will become weakened and is more likely to become damaged.
  • Check your owners manual for additional cleaning and care information for your convertible top. With all of the new chemicals and products on the market, they are complete and offer a solid understanding of what can and cannot be used on your particular convertible top.

The ARMA recommends a 1:1 ratio of bleach to water to clean a roof. They also advise against using a pressure washer on asphalt shingles, as the force of the water can damage them. After being allowed to sit on the roof surface for up to 20 minutes, the bleach solution should be rinsed away with clean water.

White Stains On Stone Roofs

The stone roof at above left has some normal light-colored areas that I do not think are a concern.

The white or light gray stains on the stone wall at above right can also appear on stone or slate or other roof materials. Lichens is not a stain in the proper sense of the word, but on asphalt, wood, or some other surfaces it can damage the roof and reduce its future life.

Worse, aggressive cleaning of lichens from a roof surface is likely to ruin asphalt roofing and other softer roof coverings.

Can I Clean My Roof Myself

Yes, but its dangerous if you dont know what youre doing. A basic bleach formula is:

  • 1 quart bleach
  • 1 gallon water
  • 1/4 cup TSP or other heavy duty cleaner

Do NOT use a cleaner that contains ammonia or is not recommended for mixing with bleach. It can result in chlorine gas, which is poisonous. If you are unaware of why you shouldnt mix bleach and ammonia, skim this article. This mixture may hurt your vegetation nearby, so be careful when using it. A professional roof cleaning company uses a mixture of chemicals that can be eco-friendly.

After you have your solution into a sprayer and you begin spraying your roof, itll become wet. Wet algae can be slippery, even more so than just a wet roof. If you plan to clean your roof by yourself, take extra safety precaution throughout the entire process.

And if thats not the case they can get your roof cleaned and back to a brand new state, free of algae and any other growth issues.

Cleaning Your Convertible Top

How to clean Algae and Mold off your roof, follow these steps!

Your cars soft top is subjected to the same environmental conditions as the rest of your car.

Although its easy to see when your cars body is dusty and dirty, it is not always obvious when a top is dirty.

This is especially true for black or navy blue!

One of the biggest wear factors for canvas tops is dust. It settles into the weave of the fabric and begins to act like sandpaper.

Vinyl tops will also experience premature wear from dirt, but not as readily.

In general, you should care for your top each time you wash your car.

But dont get carried away!

This doesnt mean you need to scrub it each time, though a good rinsing is necessary.

The following steps are highly recommended:

  • Wash your soft top at least once a month, or when it is dusty or dirty, with a non-detergent-based auto shampoo. If your top is not dirty, rinse it thoroughly with plenty of cool water. Make sure the shampoo does not contain gloss-enhancing oils. Otherwise, the top will absorb the oil and be a dust magnet. Use RaggTopp Fabric Convertible Cleaner Kit.
  • The recommended tool for washing is a soft scrub brush. Do not use a cloth, chenille-covered sponge or lambs wool mitt because they will leave lint. If your top has soil marks, stains or bird droppings then use a small and stiff upholstery scrub brush.

Was that a lot to take in?

I dont want to be incomplete when it comes to your beautiful investment.

So, heres some more tips for you.

On vinyl windows, microfiber towels work best. Hands down!

Another Less Common Occurrence Is Moss

If you see green fuzzy stuff on your roof it is most likely moss. Moss loves cool, damp environments. If you have moss on your roof it will be commonly found on the North slopes in addition to overhanging treses or overhanging sections of the roof causing shade and allowing moisture to hang around and the moss to grow.

Moss spores can become airborne and make their way onto roofs via wind, birds, squirrels, and other small animals, in the same way that algae makes its way to your roof.

Once the moss spores land on a roof, they will gather in the spaces between shingles and eventually grow into thick spongy moss.

Algae is a term for a large group of photosynthetic eukaryotic organisms. They are typically aquatic and lack the roots, stems, and leaves of other plants, though they still contain chlorophyllthe green pigments found in most plants. However, they are not plants but rather organisms also spread by spores, much like moss.

Mold is the result of algae left too long on a roof. Algae needs perpetual moisture to exist, so they grow best in humid areas. When algae keeps the roof damp for long enough, rot can set in, commonly leading to mold growing and spreading.

How To Clean Your Roof

There are several ways to clean your roof from moss, algae and mold. Use these tips as your guide when cleaning your roof.

  • Cleaning your roof can be risky. You have to go on top of it. Make sure to secure yourself in a harness. Most people will get help from a roof repair company for better results.
  • Pressure washers may be easier to use in cleaning your roof but they can damage the shingles. Use a hose attached with a nozzle instead.
  • You may spray wash the roof with 1 part water and 1 part bleach to clean off the algae. Let is sit for around 60 minutes before rinsing.
  • If you find bleach and water solution weak for your moldy roof, you may use trisodium phosphate. Mix a cup of it for every gallon of water.
  • There are other commercially available cleaning solutions in the market. Take note however of the labels and make sure youre using the right product for your roof.
  • Some homeowners are considering roof waterproofing in order to prevent moisture and mold growth. While its good to initiate for your roofs maintenance, getting help from an exceptional roofing company is still your best option.

    How To Prevent Moss On Roof

    Happily, there are preventive measures you can use to keep your roof moss-free. First, let the sunshine in! Trim branches overhanging your roof, keep gutters free of debris, and regularly remove moisture collectors, such as leaves, branches, and seedpods, that pile up on the roof and encourage moss to grow. The best long-term solution? Attach strips of zinc or zinc-coated metal flashing strips just below a roofs peak or ridge caps. When it rains, water flows over the metal strips leaching out moss-retardant zinc particles, which attach to roof shingles and/or tiles to stop new moss from forming.

    Working safe, smart, and strategically guarantees your moss-removal operations will run smoothly. These prevention measures mean youll be able to stay off the ladder and roof for seasons, if not years, to come.

    Mold stains can form on roof shingles that are in permanent shade. These stains will discolor your roof and damage the shingles over a period of time if left alone. Extensive mold growth can also expose the interior of your attic or crawlspace to mold spores, carrying the problem over to the inside. Not to worry, though, because you can clean the mold off with basic household bleach and save your roof long before you need an expensive replacement. Follow the steps below to remedy this problem.

    Protect Your Plants and Lawn

    Splash the plants and parts of your lawn that are close to the sides of your house with water to protect them from the bleach solution. You can also cover them with tarps or plastic sheeting, which will protect the soil around your plants as well. Make sure that you create a wide radius around your home to be safe.

    Make and Apply the Bleach Solution

    Check for Cleanliness and Rinse

    Allow the solution to soak into the shingles for at least 15 minutes. If they are severely molded, you may want to give it a little longer. Next, rinse the shingles thoroughly with a garden hose at low pressure. Start from the top shingle and rinse downward to prevent water seepage.
