The Ultimate Guide to Roof Cleaning: Removing Moss, Mould, and Debris

Learn the safest and most effective methods for lichen removal—from DIY tips to expert treatments. Protect your roof and your home.

If lichen has started its slow creep onto your roof, then you’re probably looking into a few different roof lichen treatment options. There are a lot of them out there, from home-brewed DIY suggestions to full-on professional-grade formulations applied by trained experts. While it’s tempting to choose the DIY route, there’s definitely a case for bringing the professionals in. Professional roof lichen treatment provides lasting results, which is a major plus when it comes to ultra-persistent lichen. Read on as we break down why choosing professional roof lichen treatment can be a major benefit for your roof, now and in the future. The Trouble with DIY Roof Lichen Removal DIY treatments might seem like a quick and easy fix, but they often don’t do the job properly. A lot of home remedies like vinegar, bleach, or store-bought sprays might knock lichen back for a while, but they don’t always get rid of it completely. Lichen is a tough little thing. It’s technically a collection of different organisms, from fungi to bacteria, so it can be difficult to kill with a single DIY treatment. That means it tends to cling on for dear life, and once it takes hold, it’s not going anywhere without a fight. Some homeowners try scrubbing it off or blasting it with a water blaster, but that comes with its own risks. Too much pressure can damage your roof, and if you don’t remove all the spores, the lichen will be back before you know it. The other issue? Most DIY solutions don’t offer long-term protection. You might get rid of what’s visible now, but without a proper treatment plan that kills the base fungus, lichen will just return, meaning more hassle (and cost) for you down the line. Why Professional Roof Lichen Treatment is Worth It They Know What They’re Doing Professional roof cleaners deal with lichen every day. They know exactly what type they’re dealing with, which treatments work best, and how to apply them properly. They also use high-quality, commercial-grade products that aren’t available at your local hardware store, so you’re getting a deeper, more effective clean. Your Roof Stays Lichen Free One of the biggest advantages of going pro is long-term protection. The best treatments don’t just kill off existing lichen; they also prevent it from coming back. That means a cleaner roof for longer and much less maintenance for you. Some companies even offer maintenance plans to keep lichen at bay, saving you the hassle of dealing with it yourself year after year. Protects Your Roof from Damage  Lichen might look harmless, but it can be surprisingly destructive. It holds moisture against your roofing materials, which, over time, can lead to cracks, leaks, and even structural issues. If you go at it with a scrub brush or a water blaster, you risk damaging your tiles, shingles, or metal roofing. Professionals, on the other hand, use treatments designed to be tough on lichen but gentle on your roof. So, you won’t end up trading one problem for another. Saves You Time and Effort Let’s be honest: climbing onto your roof to deal with lichen isn’t exactly a fun weekend project. It’s time-consuming, physically demanding, and, if you’re not careful, downright dangerous. Hiring professionals to tackle your roof lichen treatment means you don’t have to lift a finger. They’ve got all the right safety gear, equipment, and know-how to get the job done quickly and effectively. Instead of spending hours battling lichen, you can leave it to the pros and get on with your day. If You Still Prefer DIY… Treating your roof lichen on your own is tougher than calling in the professionals, but if you already have some DIY know-how, then this might be your preference. Our recommendation? Make sure you find a roof lichen treatment that approaches or even matches the professional-grade sprays on the market. Not only will finding the right treatment ensure your lichen is properly dealt with, but it will also prevent that lichen from growing back fast enough to have you out there the following weekend. Something like our DeMoss moss, mould, and lichen remover is ideal here. It’s highly effective for homeowners jumping into lichen removal for themselves, and it’s cheaper than the formulas you’ll find elsewhere. At the end of the day, the number one thing to remember when dealing with roof lichen is to act fast. While this is a slow-growing organism, the damage it creates will last for your roof’s entire lifetime. Invest in a team of professionals to kill off the infestation and spray a protective layer that repels future lichen.
