Best Time Of Year To Clean Slate Roof

How to soft wash natural slate roofs

It is important to clean your slate roof on a regular basis in order to keep it looking its best. But when is the best time of year to clean your slate roof?

The best time of year to clean your slate roof is in the spring or fall. This is because the weather is not too hot or cold, which can damage your roof.

In the spring, you can start by cleaning off any debris that has accumulated on your roof over the winter months. This will help to prevent moss and algae from growing on your roof.

In the fall, you should clean your slate roof before the winter weather sets in. This will help to prevent any damage that may occur to your roof during the winter months.

How To Clean Shingles

Roofing shingles should not be cleaned with a pressure cleaner. They require a gentler touch ideally a mixture of hot water, bleach and detergent. It’s best to clean shingles on a cool and overcast day so the mixture won’t dry too fast on the roof.

Pour the mixture into a garden sprayer and clean a one metre by three-metre area at a time. Start at the bottom and let the mixture dry before moving on to the next section. You may need to use a broom to gently scrub the shingles while they’re wet, but don’t use too much pressure or you could damage the shingles.

If the shingles start to dry out, wet them again before brushing with the broom. Finally, rinse the shingles with fresh water, making sure you’ve removed all the residue from the mixture.

How Should You Wash A Slate Roof

The best way to clean a slate roof depends on the debris build-up. In most cases, its best to remove the bulk of the moss and debris by hand using a scraping tool and then apply a nonaggressive treatment to the tiles to kill the biofilm.

The treatment will continue to work over a few weeks, with the weather helping out. While the results arent immediate, the tiles will start to self-cleanse once the treatment has started working. Not only is this method less harsh than pressure washing, but it also protects the tiles from regrowth for many years to come.

The longevity of slate is key to its value in the eyes of homeowners. After all, roofing can be expensive. Slate is one of the few roofing options that doesn’t need to be replaced within the span of a lifetime. In most environments, slate shingles will last at least 125 years and sometimes as long as 200 years. As such, slate will outlast multiple generations of occupants at a given address.

Slate is also widely considered one of the most beautiful roofing materials. As a stone, slate has a natural, timeless appeal that never goes out of style. Slate shingles complement classic homes from the 19th century as well as modernist homes built in recent decades. Moreover, slate is one of the most diverse roofing options when it comes to color. Slate tiles are available in tones of green, red, purple, grey and black.

Cleaning Roof Shingles With Bleach

One of the most common ways to clean roof shingles is with a chlorine-based cleaner, also known as pool shock. This method is effective at killing algae and will give you visible results quickly.

To use this method, mix 1 lb of pool shock per gallon of water and apply it to your roof with a pump sprayer. Let the mixture sit on your roof for 20-30 minutes before rinsing it off with a garden hose.

You should always take caution when using any chemical cleaning product on your roof. Be sure to read the manufacturer’s instructions carefully and always wear gloves, eye protection, and a face mask when handling pool shock. It’s also a good idea to test the cleaning solution on a small area before you treat the entire roof surface to help you avoid any unwanted damage or discoloration.

To clean your gutters of algae at the same time, mix 1 cup of pool shock per gallon of water and pour it into your gutters. Let the mixture sit for 15-20 minutes before flushing it out with a hose or garden sprayer.

As the pool shock rinses off your roof, you’ll want to be sure you lay down plastic to divert the chemical from your lawn or any other plants you have near your home.

Other bleach-based cleaners you can use include:

  • Chlorine bleach
  • Peroxide-based bleach

If you plan to use any of these types of liquid bleach, be sure to dilute the mixture and apply it in tiny portions directly to algae to prevent staining or discoloration.

How To Approach Cleaning

Cleaning should be limited to removing organic debris like moss and leaves. To remove moss as well as mould or rust, gently scrub with a medium-stuff brush and a mix of suitable roof slate cleaning products, such as household cleaner and water. If you see grey or grey-green streaks, these are usually from copper or zinc nails or flashing. They are harmless to slate and can help keep away moss, mould and other organic material.

You should also remove slate flakes from gutters, valleys and other areas around your roof and the chimney. It is best to use heavy rubber gloves to safely pick up the material. You should only remove debris from places you can reach from the ladder. A leaf rake can be used for areas that are difficult to reach.

To remove residual soap and remaining debris, gently spray your roof with a garden hose. Focus on one section at a time and adjust your ladder along the roof accordingly as you clean it. High pressure water including from pressure washers can break apart slate, particularly older or damaged tiles.

Cleaning Roofs With Uncommon Shingles

Distinct roofing materials require different cleaning methods. Here are some tips for cleaning roofs with uncommon shingles:

  • Clay Tiles: Clay tiles can be cleaned with a mixture of water and dish soap. Because they are resistant to most types of stains, they shouldn’t require aggressive cleaning. Just be sure to rinse the tiles thoroughly afterward, and your tiles will look as good as new.
  • Slate Tiles: Slate tiles can also be cleaned with a mixture of water and dish soap. You can also use a soft-bristled brush to scrub away any stubborn dirt or debris, but keep in mind these tiles tend to be fragile despite their weight. Do not vigorously scrub or use harsh chemicals on slate tiles.
  • Wood Shingles: Wood shingles can be cleaned with a mixture of water and bleach in a 3 to 1 ratio. You can also use a soft-bristled brush to scrub away any stubborn dirt or debris. Keep in mind that wood shingles naturally discolor over time, and while power washing might restore the standard color, it can also damage the wood.
  • Cedar Shakes: Cedar shakes can be cleaned with a mixture of water and wood cleaner. You generally don’t want to use bleach due to the porous nature of the wood. You can also use a soft-bristled brush to scrub away any stubborn dirt or debris. If you do notice algae stains, you must act quickly. Algae can cause a buildup of moisture in the wood, which can prematurely age shingles and lead to leaks.

Using A Trowel Or Stiff Brush

Roof Cleaning With A Pressure Washer

While cleaning your asphalt roof with a pressure washer might seem like a quick way to see results, it’s probably going to speed up more than just the cleaning process. Pressure washing asphalt shingles can prematurely age them by causing the granules to come off or lifting shingles and allowing in moisture.

Not only will this make your roof look old, but it will also leave it unprotected from the sun’s UV rays, which can cause the asphalt to deteriorate and shorten the lifespan of your roof.

No matter how careful you are, we recommend avoiding pressure washing your roof shingles altogether.

How Much Will It Cost To Replace My Slate Shingles

If you move into a home with slate roofing, you probably won’t have to replace the roof during the years you own the property. After all, slate shingles can last up to 200 years. Unless the house pre-dates the construction of the Statue of Liberty, chances are you won’t be the lucky homeowner to preside over the property when the shingles finally do expire. That said, you might need to get the roof maintained if damage occurs in select areas.

Two main types of problems can arise when maintaining slate roofs broken tiles and faulty flashing. Select tile replacements can sometimes rectify the first problem. If the roofing consists of hard slate, it is probably salvageable as long as you get the broken tiles replaced as soon as possible.

The most significant mistake some homeowners make in this situation is to ignore the problem until more tiles break, by which point rainwater can make its way under the slate and penetrate the roofing foundation. Once the problem has advanced to that level, the only option is a total roof replacement. Likewise, a problem with faulty flashing will generally require a a new slate roof installation or full roof restoration.

When roofing comprised of soft slate begins to crack, it is better to get new roofing. Soft slate is more liable to crack, and the cause of one crack could easily spread to other parts of the roof. If new roofing is required, consider upgrading to shingles made of hard slate.

What Is The Warranty On The Roof

The terms of a roof warranty will often depend on the manufacturer. Some warranties will cover the roofing materials against defectiveness for several decades, yet only hold the contractor liable for a few years from the completion date of an installation. Certain manufacturers will guarantee their roofing materials for anywhere from 75 to 100 years.

However, not all warranty policies transfer from one homeowner to another. Some policies do transfer, but only once. Therefore, if a previous property owner installed a slate roof a decade ago, and now the current owner wants to sell, the next owner of the property will not be able to inherit the warranty.

Policies on roof warranties can also depend on local law. In any case, when you set your sights on a home with slate roofing, research the terms of the roof warranty and whether it will be transferable to you. If the shingles were installed poorly or the tiles become damaged due to severe weather, it is best to know in advance whether any roofing expenses will be covered.

How Do You Clean A Slate Roof

Slate Roof Cleaning and Roof Algae Removal Lancaster PA

A well-installed slate roof can last without any problems for decades or even centuries. Slate is a durable, compact, dense, fine-grained rock, but above all a natural product, which makes it unique.

Each slab is unique and slightly different from the rest with its own character. As it is a natural rock, slate is alive too, integrating and adapting into its environment.

As with any material exposed outdoors, build ups of atmospheric dust, plant growth or even chromatic changes can occur. You can clean dirt build ups or plant growths relatively easily, because they respond very well to mechanical methods.

A pressure washer should suffice in most cases, although you need to bear two things in mind before you start cleaning it this way.

Firstly, take great care when moving around on the roof. Slate roofs are not designed for walking on. Only qualified professionals know how to do this without damaging the structure or putting themselves at risk.

Secondly, avoiding applying pressurised water from the bottom upwards is essential, as you would only manage to get it under the roof, along with the dirt you want to remove, if you do it that way. These two tips may seem simple, but they are often not taken into consideration.

When plant growths are removed, this microscopic pitting is exposed, presenting a much easier surface for new growths to colonise, as they have much more surface area. So, cleaning the roof is only a temporary solution in any case.
