Making sure your roof is clean and that the surface water drains from your is a vital part of any roof maintenance to ensure a long term and durable roof. Algae and moss build up on your roof will have a huge impact on the lifespan of your roof and gutter system, it can lead to gutters failing and since algae and moss both hold moisture, it can cause your roof tiles to hold onto moisture. This can cause tiles to slip or worse, damp to build up and penetrate the underlay below your tiles on your roof.
Soft washing roofs and hard washing roofs are the two most common forms of roof cleaning. Soft washing is the more gentle version and used on roof tiling that might get damaged through hard washing. The soft wash uses a soft brush along with running water which is combined to gently brush dirt off your roof. It is more labour intensive and not as 100% effective as a hard wash. However it will remove the build up of grime on your roof and this is the most important factor. roof cleaning in Dublin is a vital factor for the longevity of any type of roof.
Hard washing is the most effective way of cleaning your roof. The hard wash uses a power wash system, It will clear away all the dirt, algae and moss on it. With both the soft wash and hard wash, roofs that are heavily affected with moss or algae, we would recommend using a bio-detergent to remove the build up of the moss or algae before you do any type of roof cleaning
Another great option on a roof once it is clean is to use a tile paint. With tile painting, you can opt to make your roof any colour although we would recommend the standard slate, black or terracotta look. The added benefit to using a tiling paint is the sealing it will provide on the roof. It will help to protect the original tiles and keep off further algae and moss for a while longer.
As long as your roof is kept clean, no dirt will build up into the gutters. If a guttering system becomes blocked because of moss, it will cause degradation and the water to become stagnant in it. The added weight can cause gutters to come loose and worse, water can start to seep into your timber back boards. Avoid it all by doing a maintenance on your roof once a year.
