There are different ways of cleaning roof shingles. Ugly stains on the roof can be removed using the low pressure, eco-friendly, non-bleach method. The stains can come off using the chlorine-bleach method too. In addition to those two methods, you can also remove the stains using the traditional high-pressure washing method. Each method has its own merits and demerits. The best method is one that does not mess or damage your roof but keeps it clean by removing all fungus, bacteria, water, dirt, dust and all types of debris gathering thereon.
Effective if done right
The pressure washer is a good and effective tool with which to clean the roof. However, it presents a big challenge. Pressure washer can damage roofs. This technique, where the cleaner pumps water at high pressure while directing it to the shingles, is one of the fastest ways of loosening them up before causing total destruction. The truth is you can clean your roof using a pressure washer without causing destruction. For this to happen, you have to adhere to the following safety tips while getting rid of the moss and algae growing on the roof unhindered.
Use low settings
Pressure washer will give you the best results if not used at the highest settings. One advantage of using it at the highest setting is it helps you blast away the debris faster. However, you also have a higher chance of blasting away your shingles, which cost a fortune to replace. The pressure washer will still give you impeccable services even at low settings. Operating the washer at low settings removes all the algae and moss while keeping the shingles in place on the roof, which is where they should be and not below on the ground.
Highest settings develop leaks
At the highest settings, you will discover that water goes and settles under the roof shingles. This could present a different set of problems later. The water could form ice dams. It could also seep through the walls, thus being a risk to the structural integrity of your building. For the best results, you ought to position the washer’s nozzle at an angle. This way, water runs downward and towards the roof’s edge. Otherwise, failure to observe this correct way of using a pressure washer would mean having to spend money fixing roof leaks.
Reduce the shingles’ fragility
Normally, all roof shingles are fragile. They are delicate roof covers that need proper and safe handling. Blasting the shingles away with pressure washing equipment – while cleaning the roof – makes them more fragile and increasingly susceptible to damages. As much as the pressure washer can damage the roof shingles, you can cause extensive damages too by stepping on them. Step on the shingles with as minimal or little pressure as possible to avoid destroying them. Also, avoid standing on the roof’s peak. Instead, step only on the support beams and rafters of the roof.
Avoid standing on a ladder
Pressure washing while standing on the ladder is an incorrect way of cleaning the roof. The risk of falling from the ladder due to the imbalance created from the pressure washer is at an all time high while on the ladder. Do not attempt this even if you feel secure with a harness in place. It only takes a slight imbalance to find yourself dangling dangerously from the ladder or falling all the way down to the ground. The injuries sustained could render you incapable of working for a length period of time; thereby threatening your family’s financial stability.
If you feel unqualified, inexperienced and incapable of cleaning the roof shingles using a pressure washer, hire a professional roofing contractor for this job. It is better to part with some money and get it done right instead of attempting it as a DIY project only to end up with huge losses – in finances, time and other resources. Remember, roof cleaning not only needs the right equipment, but also the right personnel to do the job safely and efficiently. Do not risk your life or that of other people doing something you have no idea how to do.
