ATTENTION ALL HOMEOWNERS - ROOF CLEANING
There are options:
1. Get up on your roof and clean your roof.
The first to think about is safety. Water / heights / pressure / Hoses-are major tripping hazards /wet and slippery moss / soapy solutions / Spray wand kickback.
There is no more dangerous place on your property than on your roof. In addition to the normal dangers of being on the roof, the addition of water, especially on roofs with mold or algae, makes the roof slippery and even more dangerous than it would be under normal conditions. If you fall off your roof while cleaning or working on your roof…your homeowners insurance will not pay for your medical costs.
**2. Spray from the ground **
Roofing materials are designed to shed water that is falling from above. When you spray from below you are spraying water up under the roofing materials and this creates the potential to lift and damage the shingles as well as drive water under them creating leaks.
Another problem when it comes to spraying from the ground is what type of solution you are going to use. It would have to be an extremely strong solution to even begin to work at all.
Pressure Washer - You see all over the web there are some huge arguments about using a pressure washer to clean your roof. Well, what is the pressure at? You can have a pressure washer
set to spray like a water fountain. You can also have one set so high you can permanently etch your name on the sidewalk. We operate in Erie, PA. We have seen homeowners watch us and pull out there pressure washing machine and start blasting and ruining their shingles. Not realizing we are using a low pressure-high volume rinsing machine. There are 2 solutions applied before we even bring the machine out. What you see is not always what you think you are seeing. Here is a video of Brink Kanga roof in Erie, PA using a three step spray solution roof cleaning process and a high volume low pressure rinse. Erie Roof Stain and Algae Removal Video
HUGE VARIABLE - What shape are the shingles in. Water being sprayed on a roof that is 2yrs. old vs. 18 yrs. old is a huge difference. Not all roofs are the same. Shingles age and deteriorate.
There are so many variables. It is just like the argument about zinc strips. Do they work?
Well how old was the roof they were installed on. Was the roof cleaned before they were installed?
What solution was used before the zinc strips were installed. Was there a protectant spray used before they were installed. What type of zinc strip is being used. What brand? What percentage of the product is actually zinc? How much of the zinc strip is shoved up under the shingle and how much is actually going to get rained on.
I am an owner of Brink Kanga Roof in Erie, PA and we offer roof stain removal / roof algae removal / roof moss removal / and roof stain prevention and maintenance. I think that the word “Cleaning” in roof cleaning makes the whole process seem easier than what it really is.
There are workers at Brink Kanga Roof that have been roofing for 10+ years and I still wouldn’t tell them to get up on a roof and go through the cleaning process without first training them specifically in the dangers of roof cleaning. There are different safety variables to be taken in consideration.
Getting back to the question and answer. Don’t use a pressure washer. Don’t waste your time researching for weeks how to clean it properly. Call someone that is a professional roof cleaner. Ask to see their insurance. Review your contract. Review the warranty given. Then go spend the hrs. doing something fun like going to eat with your family or friends or go to an amusement park and ride on the biggest roller coaster there is…wait, you’re saying you won’t go on the biggest roller coaster in the world…but you were considering climbing up on your roof and spraying water and solution all over etc. …Think about it? Stick to the coaster. Just teasing, but seriously don’t risk your lives homeowners. There are a lot of roofers including myself that have witnessed a friend / worker that had 20+yrs. experience fall to their death roofing. Roofing can and will kill you.
