If you want more information about roof cleaners, read on to learn the best ways to clean your roof and keep it in good condition.
Can you clean your own roof?
You can clean your own roof, but there are some important precautions and tips to bear in mind before you do so. You have to ensure you use a safe, secure ladder that can be attached to the roof so that you don’t risk falling off. You might also want to invest in a safety harness, especially if you have a steep-sloped roof.
It’s best to try to clean your roof from the ground, such as with a sprayer or hose, instead of climbing it. Check the roofing material manufacturer’s clause to check what is said about roof maintenance and cleaning before you go ahead so that you can be sure you’re not doing anything that can damage the roof or void your warranty.
Be sure that you do preventative checks to inspect your roof from time to time. These include checking and cleaning your gutters, removing dirt and debris from your roof, and trimming overhanging tree branches that can damage your roof or provide the perfect shade for mold and algae to take hold.
All of these roof maintenance tips will prevent you from having to do deeper cleaning of your shingles or other roofing materials.
What is the easiest way to clean a roof?
If you’re worried that cleaning your roof will be a difficult, time-consuming task, it can certainly feel that way if you’ve never done it before. That’s why you should try to keep things simple yet effective.
The easiest way to clean your roof is to mix equal parts water and chlorine bleach. Attach a sprayer to your garden hose, then spray the roof with the solution and let it sit for about 20 minutes, before rinsing it off with water. Note that you should do this on a cloudy day to prevent the sun’s rays from causing the solution to evaporate too quickly. If you need to target specific issues, such as mold or algae, you should purchase a solution that will specifically tackle such problems.
You should also clean your roof by removing any dirt or debris that can build up in gutters and other areas. If you can safely reach these items, you can do so by wearing heavy rubber gloves. A roof rake is best to use for any debris that you can’t reach by hand.
How do you get moss off a roof?
If you’ve noticed that there’s moss on your roof, you should act quickly to get rid of it. If you don’t, the moss can cause damage any type of roof, such as wood, asphalt, metal, concrete, and clay, causing your roof to deteriorate.
Although moss starts off as a thin green layer that appears between shingles, it soon grows and lifts the shingles. This allows water to enter underneath them, which will lead to problems such as leaks and rot.
To remove moss from your roof, you might be able to get away with water and a bit of scrubbing. So, hose off the moss-laden area of the roof by spraying water on it at a downward angle. With a long, soft-bristle brush remove the moss.
Scrub from the top down so that you don’t damage or lift the shingles. If the moss is a bit more stubborn, you’ll need a store-bought product to nip it in the bud. One of the best roof cleaners to tackle moss is the RUST-OLEUM 60701 Jomax Roof Cleaner that we featured in our reviews.
What causes black streaks on the roof?
If you’ve noticed that there are black streaks running down your roof, you might have assumed this was just dirt, but it’s actually a form of algae.
This type of algae is called Gloeocapsa. Although it’s blue-green in color, when it accumulates on the roof it starts to produce a dark and hard coating. This is what causes black stains and streaks to appear on the roof.
If you don’t do anything about this algae, it will continue to produce every year and it will also become more unsightly as time passes. The algae will start to trap moisture, which can damage the shingles of your roof.
This is why it’s important to eliminate this algae from your roof as soon as you notice it. There are various methods you can try, such as oxygen bleach or formulas that contain chlorine bleach and/or trisodium phosphate.
You can also make a cleaning solution with three parts water and one part bleach, and add a teaspoon of trisodium phosphate. After applying the solution to the moss on your roof with a pump sprayer, you should leave it to work for 15 minutes. Then simply wash it off with a garden hose. You can repeat the treatment if the streaks remain.
While some roofing manufacturers treat shingles with zinc or copper to keep algae growth at bay, these methods don’t work permanently as they lose their effectiveness over time. This is why it’s best to remove the black streaks via other methods. You should tackle them without delay, otherwise they will provide a fertile spot for lichen and fungus that weaken the roof shingles.
You should clean your roof regularly to keep it free of dirt, mold, and debris, all of which can compromise its structural integrity.
