Your roof is one of the most critical components of your home because it protects you from the elements. Aside from this, your roof also contributes to the aesthetic appeal of your property, elevating the value of your home depending on your roof's condition. 

For this reason, it is essential to maintain your roof correctly, which means cleaning it regularly. This article lists everything you need to know about cleaning a roof.

Get the Help of Professionals

One of the first things you need to know when it comes to cleaning your roof is that getting the help of professionals is still the best option. This is because they have the tools, skills, and experience to clean your roof correctly. If you decide to DIY, you may not be able to thoroughly clean your roof, particularly if you lack the materials you need to do so. 

You will also be risking yourself because without the proper experience and skills, climbing up a roof to give it a good cleaning can be challenging. For this reason, reputable and transparent roofers suggest hiring a highly skilled team with decades of experience. They can ensure that they execute every roof cleaning project flawlessly. They will also likely have the tools necessary to complete the roof-cleaning process from start to finish.

When choosing a roofer to work with, ensure that they have the appropriate experience and expertise to carry out the roof cleaning tasks you need to accomplish. You should also ensure they have the certifications to prove they are trained in roofing projects. This will give you peace of mind that they can achieve the tasks they must deliver when cleaning your roof the first time. 

Another non-negotiable requirement is for the roofer to be adequately insured. If any unfortunate incident happens while they are cleaning your roof, you are guaranteed they have the proper insurance coverage to protect them. 

Fortunately, thanks to the internet, you can now seamlessly find a reputable roofer within your vicinity through online research. Most reputable roofers now have a website you can refer to when searching for their services. They also provide client testimonials on their website, which can give you an idea of what their previous clients have to say about their services. 

Apart from online research, you can also ask for recommendations from your friends and family who may know of a reputable roofer you can work with to clean your roof effectively.

Safety Precautions

Should you try to DIY when it comes to roof cleaning, ensure that you adhere to strict safety precautions. You should wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and non-slip footwear. The gloves will protect your hands from getting wounded with the debris you may find on your roof, while the safety goggles will protect your eyes while cleaning. 

Non-slip footwear will reduce your risk of falling from the ceiling. Using a harness that can help break your fall in case of an untoward incident will also be a good idea. When climbing up the roof, ensure that you use a sturdy ladder to support your weight. It would help if you securely positioned the ladder on level ground. Having a spotter to assist you and ensure ladder stability will be better.

Know Your Roof Material

You should also know your roof material and apply the proper cleaning procedures to maintain it. Different roofing materials require varying cleaning methods. For instance, for asphalt shingles, you will need a bleach solution. You will need a more concentrated solution to clear more extensive stains. 

For a painted metal roof, powdered laundry detergent, bleach, and water will often do the trick. However, you only need to apply this solution to the areas of your roof with stains. You will also need to lightly scrub the stained area of your metal roof until it is free of mildew and mold. After that, you can then rinse your roof with plain water. 

Cleaning a tile roof will require a pressure washer and a mixture of chemicals to remove dirt accumulating efficiently. The key is knowing what your roof is made of to ensure you can clean it properly.

Choose a Cleaning Method

There are various cleaning methods suitable for different kinds of roofs. For instance, a pressure washer is ideal for multiple roof types. This is also considered the most cost-effective way to clean your roof. You only need to be cautious of the amount of pressure you apply on your roof. Otherwise, you may damage your roof with too much pressure. 

There is also the option for you to try softwashing. This is where bleach is used to clean your roof instantly, but roofers will only apply the solution after manual scraping. While there is very little chance of damage to your roof with this cleaning process, it can be risky because the solution you use to clean the roof may land on other surfaces, even people, causing irreversible harm.

Some roofing contractors may clean your roof via steaming with shallow pressure. When applied to your roof, the heated steam will leave it looking like new. However, professionals are the only ones who typically perform this cleaning process because they can appropriately control the pressure and flow rate for an effective cleaning. 

Alternatively, other roofers apply a biocidal roof wash, another popular roof cleaning method. This entails manual moss removal before the biocidal roof wash is applied. Your roof tiles will likely be restored to their original color within three to six months. In this case, it is best to consult with professional roofers to gain insight into the best cleaning method applicable to your roof.

When cleaning your roof, the experts' help is still the most effective solution. Should you decide to DIY, ensure that you adhere to safety precautions. 

Aside from this, you should also know what material your roof is made of to apply the appropriate cleaning method. Apart from maintaining your home with a clean roof, you will also be elevating the aesthetic appeal of your property.
