The Best Option For Tile Roof Maintenance

How do you make roof tiles look new?

It is possible to give your tiled roof a facelift just by cleaning it. We’ll teach you how to prepare your roof tiles and show you the safest way to do the cleaning yourself. You will also learn the best way to walk on roof tiles.

Step 1. Prepare to start cleaning roof tiles

There are three pieces of advice worth knowing before you start cleaning roof tiles. Firstly, try and always walk where the tiles overlap as it’s the strongest part of the roof. Secondly, the surface of the roof gets slippery while you are cleaning, so install a safety rail and wear sturdy, non-slip shoes. Finally, you will save a lot of time if you have someone stay on the ground to pass things up to you.

Step 2. Use anti-moss spray on roof tiles

Before you start this step, disconnect any water tanks from the gutters so no chemicals get in to your water storage. Now apply the anti-moss spray across all the tiles on your roof. When you are spraying on a roof, always start on one side and walk backwards away from where you have sprayed. That way you always walk onto a dry tile.

Step 3. Clean the roof tiles with a high pressure water spray

Give the anti-moss spray time to do its job, and then use the high pressure cleaner to wash the tiles down. This will remove all the moss and lichen as well as any built up dirt. As you did in the previous step, walk backwards when you are spraying, away from the wet tiles and onto the dry ones.

By coating with paint, the tiles look like new again

High-quality clay roof tiles are very robust and therefore offer you an extremely long life. In general, they are still completely intact even after 60 years. However, old roof tiles tend to moss and dirt, so the overall impression of your roof is reduced. The color also fades over time due to the action of the sun. However, that is no reason to have the roof completely re-stocked immediately. The replacement of tiles costs a lot of money. Instead, you should consider repainting the tiles and then sealing them. This results in two advantages: On the one hand, your roof looks like new again, and on the other hand, the seal extends the service life of your roof tile.

Important precautions

After you have completely covered your roof, you will receive a corresponding one Warranty period, which can be up to 30 years. However, this warranty will be forfeited if you treat your roof tiles incorrectly. Often, the use of a high-pressure cleaner is enough to void the warranty. Without a thorough cleaning with the high-pressure cleaner, a painting of the roof is not possible. You may therefore need to wait until after the warranty period before painting your tile. In addition, unfortunately, not all roofs can be repainted. With asbestos-containing roof coverings, for example, cleaning is generally prohibited because it would disperse the asbestos dust in the air. Even some clay tiles give off after years still substances that may not come into contact with the roof color. As a rule, all roof tiles and concrete tiles can be painted well.

Step-by-step instructions

So that everything runs smoothly when you paint your roof tiles, we have one below Step-by-step guide for you

Step 1: Setting up the scaffolding

To do the work on the roof, you first need a scaffolding. Install it at the house in accordance with current safety regulations or have this work done by a specialist garage.

Your own safety is always the top priority when renovating the roof. For this reason, always consider the intrinsic safety device during all work on the roof.

A possible alternative to the scaffold is the lifting platform.

Step 2: Cleaning the roof

Before every painting, it is necessary to clean the roofs. It is done with a high-pressure cleaner and a lot of water. For safety reasons, install a gutter grille before collecting the roof, so that no dirt accumulates in the downpipe. Equip your pressure washer with a suitable attachment, such as a dirt bur. It helps you to remove stubborn dirt and moss from your roof tiles. It is important that you always adjust the pressure of the high-pressure cleaner to the surface of your bricks during roof cleaning. Bricks made of plastic and slate work with less pressure, while clay and concrete can withstand higher pressures. After removing the tiles from dirt and moss, remove the gutter grille and finally clean the gutter. Then the roof needs to dry well.

Step 3: Paint the primer and paint on the tiles

After the roof has dried, prime the roof tiles. Which primer is suitable depends on the condition and color of your roof surface. For smooth, shiny roof tiles choose a bonding agent, which is also known as primer. Even red clay tiles must necessarily be primed, because paints otherwise do not adhere due to the special chemical composition. Concrete bricks have a high suction power, which makes them very good at color. However, the absorbency is not the same everywhere, so the paint can become stained. Here the primer is required to produce a uniform suction power, so that the paint looks even.

To paint the roof, you finally use a special roof color and apply it with the paint roller. Façade paints are not suitable because they can not withstand the high loads your roof is exposed to. If necessary, you can also mix several colors to create an individual color. Make sure that you mix only roof colors from the same manufacturer. Opt for high quality colors from retailers, so that the durability is correspondingly high. Cheap paints often fade faster.

Step 4: Apply Sealer

After the roof paint has dried, apply a seal to keep the roof tiles as new as possible for as long as possible. Commercially available nano-sealants are suitable for this purpose. They are applied with a paint gun in two layers for the best possible result.

Consider Your Safety

Before you begin giving your roof tiles a spring clean, you must ensure that safety has been strongly considered. A failure to do so could lead to you damaging your roof and injuring yourself. Here are some tips on safety equipment and personal protective equipment to use to avoid these potential dangers.

  • Fit a temporary safety rail
  • Wear sturdy, non-slip safety boots
  • Wear chemical protection gloves
  • Wear wraparound safety glasses

Whilst the above safety equipment is essential whatever the size and pitch of your roof, you may also require a safety line and harness. These are vital on high pitched roofs where a build-up of moss or algae can make the tiles incredibly slippery. As well as wearing adequate footwear, when working on a tiled roof make sure only to step where tiles overlap, as this is where the tiles are sturdiest.

It is also strongly recommended that you work alongside a friend who can pass materials and equipment up onto the roof. Without someone else to work with, you will have to repeatedly climb on and off the roof. This is when most injuries and accidents occur.

How to Make Your Old Shingles Look New

Streaking, What Causes It?

The most common cause of streaking is the presence of an algae that feeds off the components in the shingles.  Other causes may include: an excessive buildup of dirt or debris, mold, or mildew.

The Effects of Streaking

Besides making an unsightly appearance, the good news is that most algae-caused discoloration has a minor impact on the healthiness of your roof in the short term. (In the long term, your roof may suffer from premature aging.)

Although your roof may not be immediately at risk of deterioration, roof stains do cause harm in a more general sense: the aesthetic appearance of your home or garage.

The presence of stains can cause a 5-year-old roof to appear 20 years old or more.  If your home is on the market, this can spell danger to a prospective bidder and prevent your asking price from being met.

How To Eliminate Streaks

Algae growth on your roof can be removed by washing the shingles with a special chemical formula specially designed to use on asphalt shingles.  There are many brands to choose from, though your local roofing contractor can help you pick out one with the right mixture.  Although many homeowners have used bleach in the past to attempt a DIY cleaning on their roof, any residue can cause harm to the shingles.  Likewise, power washing should not be attempted, as it will damage the shingles.

A better option is to contact your local roofing contractor to inspect and clean your roofing system.  Look for a contractor with extensive training and experience in roofing systems to maximize the benefits of a roof cleaning.
