  1. Watch Out for Roof Algae

You might have noticed ugly dark spots and dark streaks on your roof. They similarly look like dirt, but they really are algae. The common types of those algae are Gloeocapsa Magma.

Roof algae can seriously damage your roof’s tiles. Algae is a living thing, and it feeds off shingles. It will eat the limestone filler that’s used in shingle production, and by doing so, it can take years off of the life of those shingles.

It’s also invisible, at least in the beginning. That’s why regular cleaning is a necessity. By the time you notice it, it’s likely that it’s already done some damage.

  1. Pressure Washing Can Damage Your Roof

Pressure washing is the act of using a machine that dispenses highly pressurized water in order to clean away dirt and grime. It’s an excellent, chemical-free way to clean many different things, including parts of your home.

It isn’t always the best choice for a roof, however. It’s better for metal or concrete roofs as the high pressure can damage shingles.

The person who operates the pressure washer should be educated to handle the pressure washer like how closely the pressure should be applied with correct settings, also choosing the correct chemical plays the great role in it.

  1. Safety Is the Most Important Thing

It’s dangerous to be on a roof, especially one with a slope. Algae can be slippery, and there are a number of other factors that can cause an accident. That being said, if you decide to do it on your own, make sure that you follow every safety procedure.

And if you don’t mind forking out a few hundred dollars, your best bet is to go with a professional when removing debris and cleaning your roof.

Chemicals like caustic cleaners should be wisely used with the protective precautions like gloves, facemask etc.

  1. Don’t Clean Your Roof From Down Below

Even though climbing up on a roof can be dangerous, you don’t want to clean it from down below either, especially if you have shingles.

Shingles are interlocked and installed to handle water that comes from the top down. If you start spraying from down below, you run the risk of loosing up shingles and decreasing their adhesive strength by pushing up on them from below.

Also, try to clean your roof on calm day when the wind is not blowing. Cleaning roof on sunny day may lead the bleach solution to get evaporate so quickly and hence this limits the cleaning effect.

  1. Use Chemicals Wisely

If you have a roof that can take it, pressure washing is your best bet. It’s an excellent way to clean without using harsh chemicals. That being said, sometimes only chemicals and cleaning solutions will get rid of stains. If that’s the case, make sure you use the right equipment to do so.

Some of common equipment’s are spraying tool or hose, safety harness, commercial roof cleaner or laundry bleach, roof strain blocker and protective clothing. Use the equipment wisely and safely.
