Remove the MOSS on roof, apply MOSS OUT, power washing the driveway (not the roof) to the front door
Experience and Good Comments
After 15 years, there were moss growing on the roof. I could see moss on the roof from cross street, especially on the roof side facing north-east, with less sun shine in summary.
The total roof area is about 1500 sq.ft. My ballpark guess will say about 50 sq.ft is level 3 (1-10, 1 is least severe, 10 is most severe), another 100 sq.ft is level 2, and the rest are level 1.
Got the quota from a few service providers found on yelp and other places. (I didn't use this HHY at that moment). Tom (the owner of Master Butler) emailed me the most reasonable price.
When Tom arrived with 4 assistants (seasonal employees, who looked like high-school guys to me), he checked around and confirmed the work to do and the price. Since the new quota is almost the same as we discussed in email, let them start the work.
I was little concerned about the quality of high-school guys, for they looked so young to me. They proved I was wrong, the two guys who did power washing took the job seriously, basically cleaned every inch of the driveway and pathway thoroughly. I am impressed.
Tom and other two guys cleaned the roof and applied the MOSS OUT, see the attached pictures took by him. I should have asked him to take a picture before they started the job, so that I can show you the difference.
Now in Feb 2016, after 6 month of the MOSS cleaning job, I didn't see MOSS coming back, as I went on the roof by myself for another roof vent pipe leaking issue. I am satisfied on the MOSS part.
Tom is very easy to communicate with, and professional with his expertise.
Not-So-Good Comments
Note: technically, this is not a Not-Good-Comments, rather a fact I observe. I feel obligation to write it down, so that the reader can see the whole picture.
In Dec, 2015, after a few heavy rain in east side area, I started to observe some leaking on the ceiling in the 2nd floor bedroom. After climbing into attic, I confirmed the leaking was around 1 vent pipe (2-inch wide) on roof. Basically the vent pipe panel (rub material) didn't have the edge evenly paving on the roof as they should be, see picture. I asked the roof repair guy whether the uneven edge could be caused by the MOSS cleaning in the summary. He told me it is possible, or it might be caused by the heavy rain plus very strong wind recently.
As you can see, my thoughts are mixed. On one side, the roof had been working fine for 15 years without leaking, and started to leak after the 1st time MOSS clean job. It is naturally for me to link two things together. (There was no much raining between last Aug to last Dec, and the leaking only happened when heavy rain and strong wind. Because the leaking is not severe, a regular rain with minor wind wouldn't cause much water to enter attic. That might be why I started to see the leak in Dec, not Aug.)
On the other hand, as the roof repair guy mentioned, a few times the wind in last Dec was very strong, like a blast, which might cause the rub edge to rise up somehow. And the rub edge wasn't entirely seal before the roof repair sealed it. After 15 year, possibly it started to wear anyway.
To reader, I think you can understand my feelings. The MOSS clean job itself has been done fine. But it might or might not relate to a leaking happened 4 month later. (You can see more pictures about leaking in my another review on "DHS Heating".)
In summary, if I want to hire someone to do the roof MOSS clean again, I probably will use this Master Bulter again, because I think I can ask Tom to double check the Vent Pipe location on the roof after the cleaning job is done. He will do it with his professionalism, with no doubt.
Actually, this is something you better to let any MOSS cleaner check for you after they complete the job. And better to have them take picture before and after their job. The picture should cover the vend pipe area on the roof.
