We of course all need a secure and leak-free roof over our heads. Leaky roofs can be a real issue, and keeping a roof in good condition, free of leaks is certainly a requirement for any happy and stress-free home.
Although, roof cleaning is a prerequisite for the longevity of your roof, coating your roof takes on a new dimension. Roofs are prone to damage from powerful sunlight over time. The UV rays coming from the Sun generate extreme heat which can cause damage to the top-coat of the roof tiles. This damage then leads to erosion and before long, you have a problem or a compromised roof.
Applying a roof coating to fortify the integrity of a roof adds another layer of protection. This can help to protect the roof from leaks and the build-up of moss and mould which holds moisture. This build-up can if not cleaned or treated, destroy the roof relatively quickly. The coating provides that layer of protection and waterproofing, making sure the tiles are impermeable to water ingress in even the heavier rainfalls.
What other benefits are there when applying roof coating?
Roof coatings are manufactured with different formulas to match the type of roof material. These include:
Acrylic coating – acrylic coating has certain properties, specifically moisture resistance, weather resistance, flexibility to allow for temperature change and oxygen permeability. This type of coating is elastomeric and has a superb reflective strength, which further protects a roof from ultraviolet rays. An Acrylic coating is particularly recommended for sloping roofs and is one of the cheaper types of coating.
Silicone coating – silicone is best known for its waterproof qualities. The silicone acts as a sealant to water and air penetration, which in turn, keeps the roof temperature consistent and less open to extremes. This is a more expensive form of roof coating as it is applied in a thick coating to protect the roof.
Asphalt coating – Typically this type of coating works best on a roof that is already based on Asphalt. Flat roofs commonly use Asphalt to keep out the elements and have a strong resistance to UV with high water adaptability
Polyurethane coating – Surprisingly, some roofs do have high foot traffic due to building works or regular maintenance of HVAC. This means the surface is exposed to human traffic from time to time. Polyurethane coating reinforces the roof to protect it against abrasive damage.
How long does roof coating last?
Roof coating or even the most robust coating will wear in time. However, it does add a number of years to the lifetime of the roof. With a new roof being a rather expensive proposition, roof coating creates longevity and will save you money over time. Certain types of roofs or situations like overhanging trees means the roof is more susceptible to damage through debris, moss and other growth compromising a roof. A coating will protect the roof from this type of growth, and the incumbent sitting water that resides when such growth is prevalent.
If you want to ensure the life span of your roof, roof coatings are certainly a process that can do exactly this. They not only ensure that lifetime of the roof, but the use of coloured coatings can also create an attractive finish for your home.
