How To Remove Moss From The RoofStapleford Roofing · Cleaning and maintenance·Roofing · December 19, 2018
Buildup of dirt on your roof
It’s natural for dirt and debris to collect on top of your roof, especially after strong winds, but typically, rainfall will wash away the majority that can be seen from the bottom of a driveway. Yet, that does not mean to say that your roof is clean, the dark patches that are visible on your roof are likely to be moss, algae or fungus.
This plant, moss, is a flowerless organism that develops in damp and shady areas, and unlike many plants, moss lacks roots and reproduce by spores. Moss is able to thrive in areas where moisture levels are high, which means your roof is the perfect places for moss to grow and spread. If you have trees close by, it’s likely that their hanging branches will provide shade on parts of your roof and thus, keep areas damper for longer and enable moss to form a mat across your tiles. Trees will also provide moss with a food source and will feed off debris that falls onto the roof. If moss is left on your roof, it’s likely it’ll thicken and start to raise your shingles up, causing leaks and wood rot.
How to remove moss from the roof
You can spray your roof with moss killer treatments, usually diluted with water but do not pressure wash your shingles – this will cause more damage than good. Always spray downwards and never upwards, you do not want water seeping underneath your tiles. Also, you chance the risk of having tiles fly off in heavy winds or storms, which can lead to leaks, torn linings and cracked flashings.
To prevent moss from returning, cut overhanging branches and install strips of zinc or copper along the ridge of your roof, as close to the peak of the roof as possible. When it rains, the water that runs down your shingles will be contaminated with metal molecules, which will kill off any potential moss growth.
Very much like moss, algae enjoys moist, shaded surroundings and feeds off limestone and asphalts, which is commonly what shingles are made out of today. Unfortunately, algae can use deep staining to roof tiles, especially if they’re a light, terracotta colour. You will know if you have algae on your roof because it looks wet and slimy and makes your home look dirty, affecting you curb appeal. You may also notice that your home it particularly cold and this could be because the algae’s shiny surface is reflecting the sun rays.

Due to the consistency of algae, it can be difficult to remove and you could smear the stains further across your shingles, however, a mixture of bleach and water can do the trick. Firstly, spray the solution downwards and leave to soak for half an hour and rinse. You may not see immediate results but do avoid repeating the process because too much bleach can damage your shingles. Be careful when removing algae, this slimy substance can cause accidents and injuries, so if you’re not sure, always call a well equipped professional who will be able to provide you with a first-rate results.
You don’t get algae without fungus, this relationship is dependant on one another. Fungus develops around the algal cells because the algae offers a delectable food supply during photosynthesis. The lichen/fungus helps in return by offering shelter to the algae, protecting it from the sun and thus, keeping it from drying out.

Chemical removers are unlikely to prove effective with lichen and so you must expect to use some real elbow grease when it comes to removing lichen from your roof. To start, you will want to remove any organic matter, such as decaying leaves and twigs, before using a stiff brush to scrape the patches of fungus. Always be extremely careful when cleaning your roof, for obvious reasons such as falls and slipping on slimy algae. If you’re not well-equipped for the job or worried about damaging your roof further – always call in your local professionals.
