Roofs are one of the most critical parts of a home. It protects the home and its inhabitants from harsh weather conditions.
Its appearance can also play a role in the curb appeal of a property. This is why Roof Cleaning Sarasota is essential.
Many homeowners opt for chemical washing to remove moss, algae growth, and ugly black streaks. It is best to use a non-toxic cleaning solution.
Debris accumulation on your roof can cause a number of safety issues. For one, it can hide hazards that workers might otherwise ignore or simply fail to see. For example, when leaves and other debris cover a skylight or hole in the roof, they can obscure the location of dangerous equipment or cause people to trip over it and get hurt. In addition, debris can also be very damaging to anything on the roof itself such as units, hatches and lights. This can lead to costly repairs or even a facility shutdown.
While you can do some basic debris removal yourself using a ladder and a leaf blower, it’s best to let professionals handle this part of the job. The right professional has the tools to safely clear debris off of your roof and can handle any large or heavy items that might be lingering on it. The best time to remove debris from a roof is during a clear day with minimal wind. This minimizes the risk of debris blowing into or onto those on a ladder and causing an accident. It’s also best to avoid working on a roof during rain or snow since this introduces additional risks of slippery surfaces or covered hazards.
In addition to clearing debris, a good roof clean will remove any organic growth on the surface of the roof. This can include black stains, moss, or mildew that cling to the surfaces of your home’s roof. If left unattended, these can begin to chip or erode the roof over time and diminish your home’s overall appearance.
The most common way to remove these types of growths is by using a chemical wash that kills the organisms with antifungal and anti-algae cleaning agents. It’s important to use these chemicals in a well ventilated area with no water pressure, as too much water can damage your roof and potentially create leaks down the line.
The bottom line is that debris at your facility is dangerous to your employees, it can impede the work you need done and it can also be very expensive to remove. This is why it’s so crucial to keep up with the maintenance at your facilities and to schedule routine debris removal on a regular basis.
During the fall season, before winter’s harsh conditions take hold, is one of the best times to clean a roof. It’s important to remove debris that might have accumulated on the roof and in gutter systems (clogged downspouts and leaking roofs can be expensive problems to deal with in the future).
This organic matter is also food for moss and mildew and provides cover for birds who peck at the shingles – this damages shingle integrity, causing leaks into the home. This damage also provides a breeding ground for mold, which spreads throughout the house and can cause health issues and wood furniture rot.
Before applying a chemical solution it’s good to run a water hose over the surface of the roof, to simulate rain and test for any areas where moisture may collect. Moisture and standing water are the greatest engines for moss and mildew, because they suck up all the sun’s heat, which in turn sucks up the air conditioning energy.
To prepare for the actual cleaning of the roof, use a non-filming detergent, such as trisodium phosphate, to wash off any dirt or contamination from the surface of the roof. This will also help to remove any loose debris and rust from metal surfaces on the roof. After washing, rinse the detergent off with a non-chlorine, low-pressure water sprayer, or even better – a pump style garden hose sprayer, to ensure that you are not overspraying the solution onto the plants around the house.
If you choose to use a diluted bleach solution to treat the roof for algae or moss, mix 50% laundry strength liquid chlorine bleach with 50% water and apply it to the roof using a sprayer. This can be done from the safety of a ladder or by climbing onto the roof itself if necessary. When spraying, it’s also important to cover the entire area of the roof evenly so that no spots are left untouched.
This treatment is a fast and effective method for removing hearty algae, fire moss or lichen, and it can be done on an overcast day, as the sunlight will not accelerate the drying process. It is also a good idea to re-soak any plants that may have received mist or over spray from the Pool Shock mixture, as this will insure that they will be safe for the next rain.
Although the roof is out of sight and out of mind, it can become dingy and dirty over time. Having a clean roof helps protect the home and extends its lifespan. The cleaning process removes mold, mildew, lichen and moss from the roof. It also removes stains from water and other liquids. It can also remove oxidation from metal roofs. A professional cleaning service uses low-pressure washing to avoid damaging shingles and other roof materials.
There are many different cleaners available to remove various types of stains from a roof. Some are more effective than others at removing specific stains. For example, bleach cleansers are excellent for removing black streaks caused by algae. They are also useful for removing grease, dirt, and other organic growth from the roof.
Some contractors mix their own homemade formulas to clean a roof. They combine high-strength chlorine bleach with a host of other chemicals, such as phosphates and other detergents. This haphazard chemical concoction not only poses health and safety concerns for those working on the roof, but it can also create toxic fumes that can drift down the block and expose your neighbors to the same dangers.
If a contractor tells you they are using bleach to clean the roof, be sure to ask them what concentration of bleach they are using. Typically, the bleach sold in grocery stores is at a concentration of about 5.75%. However, some contractors may be able to purchase industrial bleach at higher concentrations.
Other cleaning products that are safe for most roofs include copper sulfate, sodium percarbonate and zinc strips. The asphalt roofing manufacturers association recommends a mixture of household strength sodium hypochlorite (pool chlorine) and water to kill moss and algae. The solution should be applied to the north and west-facing areas of the roof, as these are the most prone to colonies of blue-green algae and moss.
Before the cleaning process begins, it is important to pre-soak the roof. This will help the cleaning solution to cling to the roof and provide maximum efficacy. It is also helpful to soak the gutters and landscaping with water, as well. This ensures that plants and trees are not harmed by the cleaning chemicals.
A clean roof extends the life of shingles and reduces damage from mold, mildew, and algae. It also improves the appearance of your home and can reduce energy bills. The first step is to sweep up loose debris, dirt, and moss. It’s important to use a long-handled brush meant for this purpose and not a pressure washer, as the high-pressure jet can rip off shingles or tiles. It’s also important to choose an eco-friendly cleaning product, as this will help protect the landscaping under your roof and prevent animals and children from ingesting harmful chemicals.
You can find noncorrosive, eco-friendly cleaners at most hardware stores. They’re usually a mixture of water and bleach. Follow the directions on the label to determine the appropriate ratio of water to cleaner. It’s best to start at the lowest level of your roof and work your way up. This will minimize drips and allow the cleaner to penetrate the moss, algae, or dark stains better. It’s also a good idea to choose a day with overcast weather, as strong sunlight can dry the cleaner and make it difficult to rinse away.
After spraying the cleaner onto your roof, let it sit for about 20 minutes before rinsing thoroughly with standard clean water. Depending on the weather, you may need to repeat this process several times. Rinsing helps to remove the spores that cause the black streaks, fungus, or algae growth. Once these spores are removed, new growth will die, and the stains and discoloration will gradually disappear.
It’s also a good idea to do a thorough inspection of your roof after each rinsing cycle. This will give you an opportunity to repair any damaged shingles or flashings and to check for any signs of leaking. You should also take this opportunity to trim back any branches that hang over your roof, as these can drop leaves, twigs, bird droppings, sap, and other unsightly materials on your home and on the cleaner. Also, it’s a good idea to clean out your gutters so that the cleaning solution can drain from your roof during rinsing.
