Steps to clean roof:
Once you understand how vital roof cleaning is, learning the steps to clean, it is the next thing you should learn. Tip: Check the weather forecast before cleaning; you do not want the rain to muddle with the process.
1. Get a safety harness:
Safety first is a rule that everyone should keep in mind. The growth of bacteria and algae tend to add to the danger factor by making the shingles more slippery. The sloping roof, combined with its slippery texture, makes it hard for cleaners to stand without a safety harness. A safety harness will help the cleaner to stand firmly and go for roof cleaning properly.
2. Get the required tools:
The necessary tools include pressure boosting pumps. These tools are far more effective than ordinary garden hoses. It releases water like jet-sprays, which are incredibly useful in cleaning out the patches and stains. It eliminates the need for rinsing and scrubbing.
3. Soaking the roof:
Soaking with water can significantly ease the process of roof cleaning. For soaking the roof properly, one needs to start spraying from the bottom of the roof and move towards the peak. Water needs to be sprayed until there is a visible runoff. It is a signal that the roof is thoroughly soaked and it does not require any more soaking.
4. Get the required washing agents:
While bleach may be the most recommended product to clean a roof around the market, it is a significant corrosive agent and can damage the roof shingle significantly. Sodium Hydroxide, commonly known as lye, works better than bleach and is not corrosive at all.
5. Use the pressure boosting pump:
It is recommended to use this tool at its lowest setting. Failing to stick to this rule will lead to damaging the roof considerably. Even at the lowest settings, the pressure of the spray is enough to dislodge algae formations and the stains. Use the pump to spray water over the lye or soap covered roof. It is essential to go slowly once you start. Haste will only cause you to clean in uneven patches.
How to prevent regrowth?
Houses that are built in places with a humid climate tend to the re-formation of bacterial and algae growth in as little as two years. Installing zinc-copper strips all along the length of the roof will lead rainwater to pick up the ions from the strip. These ions are highly effective in keeping the roof free from growth and require lesser roof cleaning.
There is another way of preventing regrowth. It is done by spraying a stain-blocking solution right after completing the cleaning process.
