Roofs perform several functions in a home in Northern Beaches. A roof keeps debris, water, snow, heat and other stuff outside. A roof helps make the house energy-efficient. If the roof of a house is not maintained, then it will stop functioning as it is supposed to. On the other hand, well-maintained roofs last longer and they make a home look appealing at all times. It is the job of the homeowner to maintain their roofs. Maintaining a roof requires cleaning it.
The cost of cleaning a roof depends on several things among them the roof material, the slope, design and size of the roof. The method to be used to clean a roof will also depend on the material of the roof. Below are the factors that determine the cost of cleaning a roof. See metal roofing Northern Beaches.

1. The roofing material used

Asphalt – Asphalt shingles are pretty delicate and care should be taken when cleaning them. Pressure-washing should be no more than 30 psi. When cleaning the shingles, care should be taken not to use corrosive detergent.

Ceramic tile – These tiles are quite hardy and they can stand high-pressure washing. They don’t corrode easily too. Still, care should be observed when cleaning these tiles because the wrong amount of pressure on a tile might make it break. Low pressure and soft-wash is recommended.

Slate – Slate is popularly used on luxury and upscale homes. They are very durable and can serve up to 200 years. They are very delicate and pressure washing is not generally recommended.

Concrete Tile – In rainy temperate climates, the concrete tile roofing is very popular. The surface of these tiles is porous and usually gathers moss. Over time the tiles wear out. Cleaning involves scraping and then applying chemicals such as zinc sulfate.

Clay Tile – These tiles are made using clay and sand. They are popular because they are good insulators and they reduce the cost of cooling. They are delicate and pressure-washing is discouraged.

2. The roof design, size and shape

Even the height of a roof do influence the cost of cleaning. If the roof is very steep, then the cost will be high because of the risk involved. As for the height, if the house is two stories, then the cost will be higher because special climbing equipment will be required.

3. The house location

The location of the house is another factor which will determine how much it will cost to clean a roof. The roof of a house that is near a road or a source of chemicals will need more time and effort to clean. A house in the countryside where not much dust and chemicals gather will be cheaper to clean.

4. The extent of moss and algae on roof

The extent of moss and algae accumulation can increase the cost of cleaning a roof. If a house is surrounded by very tall trees which keep the roof to be constantly in shade, then it is likely that algae and moss will gather. Houses in places where it rains a lot and is moisture often have moss and algae gathering in the gutters. Regular cleaning is required and the cost is a bit high.
