Causes of Algae Growth in Roofing Http://www.morriscountyroofers.com
Clay tile house tops are mostly affected by rain water and dust. Dust accumulates in the tile grooves and subsequent rains may cause formation of humus or algae. Algae end up depositing the green color materials on the tile which may end up absorbing water and start leaking into the building. Accumulation of humus tends to facilitate a good environment for plants to grow. Humus and algae are to scrapped off by periodic checks and faulty tiles replaced. Tiles may also loose position by tilting as a result of weather aspects like wind.
Sources of leaks in roofs should be identified and amply repaired. Causes of leaks could be rusting, nail holes from missing nails or from poorly joined components. The leaks are best checked from the interior of a roof. Fixing the leaks depends on the type of material that has been used. Adhesives like bitumen is applied on iron sheets or the sheets are nailed again.
Loose sheets as a result of blowing wind are nailed back as soon as possible to avoid more roof destruction. Strong winds remove nails by moving the sheets upwards and this weakens the house top. Weak house tops can be very dangerous in times of storms.
Cement roofs are well maintained by getting rid of all debris accumulating on top in order to reduce the possibility of moss and algae growth. Accumulation of water may weaken the cement and make it disintegrate. All tree branches above buildings should be cut to minimize the amount of debris falling.
The best maintenance to be performed is semi annual inspections to discover and fix problems as soon as possible. Since the roof is the top most part of the structure it tends to get more abuse from elements than any other part of the structure. Proper and timely maintenance operations go in a long way in avoiding major repairs and overhauls. Major roof renovations are very expensive to fund partly due to the technical know how of builders required and the high cost of materials. Better longer service is hence obtained by carrying out proper maintenance.
