If you’re considering pressure washing your roof, there are several things you should know first. Power washing a roof will remove protective granular from shingles, leaving them susceptible to damage. It will also leave gouge marks on the lower layers of the roof. Plus, it will make the shingles and gutters vulnerable to the elements.
Cost of pressure washing a roof
A basic roof cleaning will cost between $0.30 and $0.75 per square foot. This cost will vary depending on the size of the roof and other factors, such as the conditions of the surface and the type of material used. If your roof is made of concrete or asphalt, you should opt for a soft wash method. This method uses very low pressure to get rid of algae, moss, and bacteria on your roof. After the cleaning process, you can rinse the area with fresh water.
The amount of debris and dirt on the roof will affect the cost of pressure washing. A heavier load of dirt and debris means more time and effort to remove, which can increase the cost. Another factor is the level of experience of the crew. An experienced crew will charge more than a novice crew.
Dangers of pressure washing a roof
Pressure washing a roof may seem like a no-brainer – but it’s important to remember that a high-pressure stream can damage important components of your roof. Water sprayed on a roof from a pressure washer is 50 times more powerful than a normal garden hose. As such, a pressure washer can quickly become uncontrollable and cause an accident. The danger of water entering an electrical panel is particularly significant, as pressurized water can cause electrical shock or electrocution.
A high-powered pressure washer can also damage the surface of roof tiles. Many roof tiles are made of concrete and are designed to gradually wear away, but using a high-powered pressure washer can ruin the granular finish on the exposed side of the tile, reducing the lifespan of the roof.
Cost of no-pressure roof washing
If you’re looking for a cost-effective way to clean your roof, consider hiring a no-pressure roof washing company. While this method of cleaning costs more than pressure washing, it is more thorough and gentle. It kills moss and algae, rinses away dirt, and does not damage the structure of your roof.
However, you should be aware that there are some drawbacks to this method. For instance, it will not produce immediate results. While black stains will come off immediately, solids like moss or lichen will die and come off after a few rains. While no-pressure roof washing won’t get rid of every speck of algae, it will make your roof look cleaner for longer. A typical no-pressure roof washing company will charge about $0.10 per square foot.
When hiring a no-pressure roof washing company, you should look at the area where they work. This service is often cheaper in larger cities. However, if you live in an area with a lot of dirty roofs, you may have to pay a little more.
Is it safe to pressure wash a roof?
While it might be tempting to pressure wash a roof yourself, it’s better to leave this task to the professionals. These roof cleaners will use a special soft wash technique to remove algae, moss, and dirt. This minimizes the risk of damaging your roof or your home.
The high-pressure water can damage the roof’s material and the seals that keep it watertight. It can also cause leaks in the roof. If you’re not experienced with the procedure, you may end up with uneven strokes or even zebra stripes.
There are many safety precautions to take when pressure washing a roof. First of all, you should use a sturdy ladder and non-slip boots to protect yourself. You can also wear protective eyewear.
Is it eco-friendly to pressure wash a roof?
If you are looking for an eco-friendly way to clean your roof, pressure washing is not the answer. While there are some eco-friendly ways to clean a roof, power washing can have damaging effects on your roof. For example, a high-pressure cleaning process uses toxic chemicals that can damage the roof. It is also not very effective at killing algae at the root level. If you want a more eco-friendly way to clean your roof, you can use a no-pressure formula.
A soft wash system uses a low-pressure pump spray to wash the roof without damaging the roof or compromising its structural integrity. This method is not only safer for your roof, but also prevents roof rot and other health risks associated with mold. Plus, it increases curb appeal.
