San Antonio Roofing: Article About Only Use Professionals For Roof Cleaning
Most homeowners do not get very excited when the time comes to replace a roof. Depending on the size of the home and the materials used, replacing a roof can be one of the most expensive repairs a homeowner can make. That is why it is so important to take every step necessary to extend the life of a roof for as long as possible. A large part of protecting the roof is cleaning and maintenance. In order to make sure the roof is cleaned and maintained correctly, a homeowner should only use the services of an experienced San Antonio roofing company. Those who attempt to do the job themselves can actually damage the roof and diminish its lifespan by cleaning incorrectly.
The type and frequency of cleaning and maintenance required will depend on the type of roofing material used. It also depends on where the home is located. For homes that are in more moist and humid climates, the roof will typically need to be cleaned more often to prevent algae and mold growth.
Over time, some roofs will begin to look dirty and have dark streaks running from top to bottom. The streaks are usually much darker at the bottom. Many will mistake this dark matter for dirt that has built up after so many years.

However, this is not dirt at all; it is algae growth. The algae will grow a dark covering that looks like dirt in order to protect itself from the heat and harsh elements. After the algae starts to grow, moss and lichen will normally begin to grow. However, the homeowner will usually not even be aware of its presence. Only after cleaning will the moss and lichen be visible as it will turn white.
Once the algae, moss and lichen start to grow, they will compromise the integrity of the entire roof. Unless properly cleaned away, they could cause the need for an entire roof replacement.
It is quite a common occurrence to drive down a residential street and see a homeowner pressure washing an asphalt shingle roof. Little do those homeowners know that they are doing more harm than good to the lifespan of their roof. A pressure washer should never be used on a roof for cleaning as even low pressure washing is detrimental to every shingle on a roof. An experienced roof cleaning company will follow proper cleaning guidelines that will preserve the integrity and lifespan of an asphalt shingle roof.
