Roof Cleaning 101


Why is my roof so dirty?

Here in Southwest Florida, black roofs are a common sight unfortunately. It looks very unappealing and what that nasty black stuff is an algae called Gloeocapsa Magma. They are an airborne spore that lands on your roof and attach via a small root structure. When this happens, the roots attach to the pores and granules of your tiles and they begin to break down the fibers. This ultimately shortens the life of the roof and the longer the algae remains, the more damage it will do. It is imperative you have a pressure cleaning professional come give you an estimate before it is too late.

Why should I get my roof cleaned?

Having a clean roof also means a cleaner atmosphere for your friends and family. It will also extend the life of your roof, keep energy costs down and increases the curb appeal of your home. Lastly, most HOA require homeowners to maintain a clean roof.

Can I just pressure wash my roof myself?

Tile and shingle roofs should never be pressure washed in certain ways. Understanding the dangers in high pressure washing a roof is key to not damaging your roof. First of all, here are two important terms to recognize.

PSI stands for pounds per square inch. It is a measurement of the pressure that is applied when breaking the bond between the grime (mold, algae, dirt, etc.) and the surface from which it is stuck.

GPM stands for gallons per minute, and this is the key factor for the effectiveness in pressure cleaning a roof. Basically it is how quickly the water comes out of the pressure washing machine. 8 gallons per minute will clean an area in half the amount of time as 4 gallons per minute.

So, in summary, choosing to pressure clean your own roof may not be the best option when you could hire a professional like Mr Pressure Cleaning who knows the correct way to clean a roof without causing any damage.

Is Mr Pressure Cleaning the right company for me to have my roof cleaned?

Absolutely! We at Mr Pressure Cleaning do not use high PSI when cleaning roofs and we utilize a tank of water hooked up between our machines and your hose spigot to allow an increase of GPM. The great advantage of a high GPM capacity is that it provides high volume for a thorough clean, while still cleaning gently with a lower PSI. We are also a licensed and insured company with years of experience in pressure washing and roof cleaning.
