Roof Cleaning: Why Is It Important?

Jan 10

Homeowners go to great lengths to keep their homes clean and fresh. They are mowing the grass, shovelling the sidewalk, power washing the deck and siding, repainting, and doing other tasks. On the other hand, Roof cleaning is something that many homeowners overlook. When it comes to keeping your house clean and elegant, your roof and gutters may be less of an aesthetic aspect, but that doesn't mean they're any less necessary to maintain clean. In reality, it's one of the most crucial sections to keep in good condition. Unlike many other cosmetic enhancements that homeowners may be concerned about, cleaning your roof can help you avoid costly damage.

Things That Can Damage Your Roof 

It is not only dirt and debris that can accumulate on your roof. Because it is frequently exposed to harsh weather daily, a lot of additional debris may build on your roof, affecting its visual appeal, performance, and lifespan.


Gloeocapsa magma, a kind of algae, is responsible for the black spots on your roof. GM algae grow in chilly, dark, and wet areas on the roof. They are most commonly seen on limestone and asphalt roofing, and they significantly weaken the structural strength of your roofing system over time. GM algae are more likely to be discovered on the roof's sides that are not frequently exposed to sunlight.


Moss is a plant that needs a lot of water to live. Moss may also readily spread to a home's interiors or even to neighbouring properties in the area. Moss spores can create health problems in individuals who live in the house if they are left neglected for an extended period.


Lichens, a fungus-algae hybrid, are most commonly seen on roofs with high humidity. For sustenance, lichens can branch down to the base of shingles. As a result, they are challenging to remove. They also have a high recurrence rate following heavy rain.


Mould is a poisonous fungus. Mould reproduces by producing microscopic spores that float in the air and cannot be seen with the human eye. While most people's immune systems are resistant to modest amounts of these deadly spores, those with compromised immune systems, allergies, severe asthma, or lung illness who inhale the spores are in danger of health consequences. Your home's structural integrity is jeopardized as a result of roof mould. As mould grows, it digests the surface to which it is attached, tearing down and weakening it in the same way that termites do. Roof mould damage may be costly if not addressed soon.

Why Roof Cleaning Is Important

Regular maintenance should include more than just repairs; homeowners should also keep their roofs clean. Roof cleaning is an important part of house upkeep that should not be disregarded. Homeowners may incur significant fees if appropriate roof cleaning is not performed.


When you maintain your roof clean, you prevent a variety of roof issues that might significantly reduce the lifespan of your roof. The expense of cleaning your roof is not inexpensive, but it is relatively reasonable when compared to the cost of replacing your roof. You can significantly increase the longevity of your roof by keeping it clean, which can save you a lot of money on roof care, repairs, and replacements.

Increase Roof Lifespan 

Your roof is the most critical section of your house, aside from the foundation. When you're inside, it's in charge of keeping you and your family comfortable and safe. As a result, you want to do everything you can to preserve it in good condition. Roofs usually endure between 20 and 30 years. Asphalt shingles and fibre cement shingles, for example, can endure anywhere from 20 to 25 years. Slate, tile, and copper, for example, can endure over 50 years. You also want to extend its life so that you don't have to spend thousands of dollars on new roofing any sooner than necessary. You may save money in the long term by getting your roof cleaned. Regular roof maintenance allows you to detect any typical problems with your roof before they become dangerous to your home's health.

Improve House Appeal and Market Value

If you want to sell your home, having your roof cleaned might be a low-cost approach to boost the perceived value of your home. Remember that even if your roof is still in good condition, a filthy roof will turn off potential buyers. Because most individuals seeking to buy a property aren't roofing specialists, a dirty roof can lead potential buyers to believe that the roof needs to be replaced. Roof replacement is expensive, and purchasers will very likely deduct this cost from your asking price. Keeping your roof in good condition throughout the selling process is a wonderful strategy to ensure your home sells for its full value.

Maintenance is Vital 

You could believe that the main advantage of cleaning your roof is that it will appear nicer, but this is not the case. Roof cleaning is, in fact, a crucial part of extending the life of your roof and maintaining it in excellent shape. When your roof isn't cleaned for an extended period, it can develop significant moss and algae. If left unattended for too long, this ugly condition can worsen, resulting in the formation of lichens on your roof. These will not only make your property appear run-down, but they will also do substantial damage to your roof tiles or shingles. Lichens add to regular roof wear and tear. These growths can freeze if left during the winter, causing them to enlarge and cause frost damage to your roof's surface.

Is Roof Washing DIY? 

Roof cleaning not only keeps your roof looking good but also preserves your investment by extending its life. A happy house starts with a healthy roof. A comfortable place without foundation damage, insulation loss, or water intrusion caused by a damaged roof. When you maintain your roof clean regularly, you extend its life and lower your home maintenance bills. While it may be tempting to attempt roof cleaning on your own, professional roofers and roof cleaning firms such as Brennan Roofing Melbourne are highly recommended.
