How to Clean Roof Tiles | DIY Methods With Recommended Tools

This article is meant to educate us on how to clean roof tiles and various relevant topics discussed in the articles.

To extend a roof’s life, it is essential to carry out annual maintenance consisting of washing, defoaming, and treating the coating. To clean the top of your home yourself, follow our articles for recommendations.

How to maintain your Roof Completely

  • Plan the application of treatments according to the weather. Ideally, the weather will be dry. Also, avoid periods of strong wind or high heat conducive to the evaporation of products. If cleaning in winter, wait for the foliage to drop altogether.
  • Preventively spray an anti-foam and algaecide liquid about once a year.
  • To limit the appearance of moss and mold, prune trees near the roof, and prune vegetation along exterior facades.
  • On a tiled roof, waterproof the surface with a water repellent product to improve waterproofing. For more effectiveness, apply the treatment in several layers.
  • Respect the dosages and action times of the products (some agents require rinsing).
  • Choose organic treatment products that respect the environment over polluting chemicals.
  • For cleaning a roof made of terracotta tiles, never use bleach because it increases the tiles’ porosity and weakens them.
  • To strip a surface with Kärcher, position the jet in the direction of the water flow, and move from top to bottom.
  • For particularly aggressive products, use a mask to protect yourself from odours that sometimes cause headaches or dizziness.
  • Equip yourself with a protective harness connected to a safety point if the roof slope is marked. Work in pairs for safety.

How to Clean Roof Tiles

A well-tended roof with clean tiles is an attractive sight and helps maintain the entire building’s value. However, cleaning the roof tiles is difficult due to the elevated location and cannot be carried out as quickly as cleaning the facade. The following eight tips should make it easier for you to clean the roof tiles so that your house becomes an eye-catcher in your neighborhood.

Step-1:

Do not rely on the high-pressure cleaner if you want to clear your roof of moss, leaves, and other dirt. Instead, make an effort and first remove the coarsest dirt manually, such as a ladder, broom, or scrubber. This increases the chances that later cleaning with high pressure will be more effective and that your roof will be cleaner.

Step-2:

Moss cushions are among the most common problems with dirty roofs, which unfortunately cannot always be easily removed with a broom. If you have noticed a strong moss infestation, manual pulling out is still the most effective way of removing it.

Step-3:

To delay a new infestation with moss for as long as possible after cleaning the roof tiles, special protective coatings are available in the hardware store. When purchasing it, it is essential to pay attention to water vapour’s permeability, so not every protective varnish is equally suitable for sealing the bricks.

Step-4: 

A high-pressure cleaner only makes roof tiles effective if you encourage the dirt to drain off in the right direction. Therefore, always work with the heater in which the moss and dirt should flow away, instead of merely holding the water jet on the brick without specifying the direction.

Step-5: 

If you have recognized algae on your tiles in addition to moss, the simple water jet to clean the roof tiles is not sufficient. Instead, work with unique substrates waiting for you in specialist shops and address the algae problem. Whether you apply the cleaning agent manually and use it to clean the bricks or whether you can connect to a high-pressure cleaner depends on the technical device.

Step-6: 

To apply protective roof paint, do not wait until the individual shingles are completely dry after cleaning the roof tiles. Most products from specialist retailers are designed so that the paint can still be applied to the damp bricks. The protective coating does not necessarily have to be involved with a brush; spraying on is also possible and ensures that the colour is evenly distributed.

Step-7: 

Don’t hesitate to clean the roof tiles out even if you have planned on applying a protective coat of paint as a last resort. Modern protective products from specialist retailers can withstand rain and other precipitation forms just a few hours after being applied. Cleaning on a sunny day is possible, even if bad weather is expected in the evening.

Step-8: 

If you are unsure when handling the ladder or challenging to reach large roof tiles, you should seek professional help cleaning the roof tiles. This may cost a bit more money than cleaning yourself, but it offers you the security of an optimal completion without the potential risk of injury.

Apply copper sulphate

Copper sulphate can be sprayed on roof mold, allowed to settle until mold turns brown, and then swept up with a broom. After removing mold, spray the ceiling with water and be sure to rinse the metal gutters.

Regardless of how you clean your roof, be sure to take safety precautions, as moisture and everything that grows on it creates a slippery surface.

How to Clean the Roof of your House Step by Step Guide

If you have noticed that the roof is filthy in your home, then it is time for you to take action on the matter. Don’t let it blacken completely or mold. Well, then it will be more challenging to clean it.

Perform a periodic review

First on the list of how to clean the roof is to do a routine check to determine its condition. At that time, you should note not only the dirt and stains that may have appeared. But you will also have to inspect if you need to make any repairs.

Therefore, check the tiles and see if they are damaged or if they need to be changed. After all, old ceramic tiles can become more permeable and will not do their job.

Pick the right day

Now is the time to learn how to clean the roof and for that, you must choose a suitable day since it is better to do it during a cloudy day to avoid exposing yourself to solar radiation as much as possible. However, we recommend using the respective sunscreen since although it is dirty, the Sun is still present.

Not only will this, because the intense heat will hinder your work, causing the cleaning solutions to dry faster than they should and, therefore, not be able to act as effectively. Of course, a rainy day is not the best either, as the water will wash away your cleaning solutions. On the other hand, a windy day would make your work difficult.

Eliminate the enormous waste

Having the best conditions to start, you should start trying to sweep the roof with a firm bristle brush. So take the opportunity to remove the branches, dry leaves, and other debris that may be on the surface. If you think it is challenging to do it manually, you could help yourself with an air blower.

Use a cleaning solution

Now that the more considerable dirt has been removed, you will probably have to fight the remaining stains. Of course, we mean the mold and moss that are more attached. There are many alternatives in this aspect available on the market.

However, if you are looking for a homemade mixture, we inform you that you can create it only with water, bleach, and trisodium phosphate.

The first thing you will do is use the appropriate protection, gloves, safety glasses, and a mask. After all, remember that bleach can be harmful if it comes in contact with skin or mucous membranes.

Remember that you should never mix it with ammonia so that it does not release toxic fumes.

Now use the hose to soak the shingles from top to bottom (you could use pressurized water if possible). Then pour the solution with 1 litre of bleach, 4 litres of water, and trisodium phosphate.

However, try to spread it evenly and in sections so as not to leave anything untreated. Once everything has been sprayed, let the product act for about 20 minutes, and then you can scrub with a brush if there are still parts with very adherent dirt. Finally, you would only have to rinse the surface with clean water and let it dry.

Clean the gutters

Although almost the entire roof has been worked, this element remains uncleaned. Don’t forget them, or you will have problems later. So find a ladder high enough and place it so that you have access to the gutters (remember to use the protection we mentioned before). Once in position, then begin to remove all the dirt with a brush (you could even help yourself with a spatula if necessary).

After the most massive dirt has been removed, you should rinse the surface with high-pressure water. After this, you can apply the same cleaning solution that we used before. However, the most important thing is that you make sure that everything can drain without problems.

In case you discover a problem and repair is necessary, do not hesitate to call the professionals.

Best Rain Gutter Cleaning Tools

For this type of cleaning, several essential tools are essential: 

Stairs

Heights are dangerous; everyone knows it. Choosing the right type of ladder can be the difference between being safe and exposing yourself to a life-threatening fall. As a general rule of thumb, use a stepladder for one-story homes and an extension ladder for a two-story house. 

Ensure your ladder shows no signs of damage like rust, dents, or anything that could cause it to collapse while you work. Additionally, be sure to position it on solid ground and have someone hold it if necessary. Consider purchasing aluminum ladders, as they are light but sturdy.

  • Dimensions - Max A-frame height: 15' | Min A-frame Height: 8' | Storage Depth: 8" | Storage height: 8'7'' | Weight: 66 lbs.
  • Take this ladder where no other 15-foot A-frame can go, including tall staircases, stadium seating, theaters, and other sloping or uneven surfaces.
  • Replace much more expensive power lifts, scaffolding systems with a ladder that is much easier to use, store, and maintain.

Palettes

There are a wide variety of trowels on the market to help you clean your gutters. To facilitate your work, select a pallet designed for gutters, as these best fit your gutters’ measurements and are made of materials that will not cause damage.

Pressure Hose

To remove debris as quickly as possible, choose a hose with adjustable pressure. This tool sprays a generous stream that will remove residue immediately.

Gloves and Safety equipment

Washing your gutters with your exposed hands is not very smart. Rodents, birds, mold, and sharp edges are just a few of the things that debris in your gutters can hide. Wear work gloves to protect your hands; you can even wear latex gloves under these for an extra layer of protection. Remember to also protect your eyes by wearing safety glasses, and wear a dust mask to protect yourself from mold spores.

Plumbing Snake

When cleaning gutters, many beginners limit themselves to just the central gutters and forget about one essential piece: the downspout. It’s a fact that unless you use a leaf filter, your downspout could also have a buildup of debris that could clog it if neglected. Now, how can you unclog a long, closed pipe with a plumbing snake? This is a drill machine that you can insert into your downspout to help break up any solid mass inside so that you can rinse it out later.

Vacuum or a leaf blower with extension

This way, you can vacuum or expel the leaves and other debris that clog them, speeding up the cleaning process. These tools’ shortcomings are that they do not work for homes with more than two stories since extensions of this length are not readily available in stores. They are also not very efficient at cleaning wet debris because these tools do not generate enough force to lift heavy debris.
