In Connecticut nothing has shown up on the first roofs we did 2 1/2 years ago. I'm pleased about that.

Not here in Florida!

I have had shingle roofs start to get green again, in little over a year, and tile is even worse!

We only give a 1 year warranty.

Up North, a 2 year warranty seems to be about the right length, for no worries.

typical results should be about 3-5 yrs.

 That's what I tell every customer.

They say "How long does the cleaning last?"

I say "All roofs are different, depending on moisture in your area, like on a golf course, with daily sprinklers running, sprinkler systems at your home, trees near the home, being on a lake, stream or canal and other factors, such as the porousity of a tile roof. Most roofs need to be cleaned every 4 years, to stay looking decent. Some last 5 - 6 years, some need cleaning after 2-3 years."

I have had 100% positive replies to that.

Hey Chuck,... maybe  I'm now going to go by "Raystown Ray", actually here at Raystown Lake,..there is a mythical creature that has been known as "Raystown Ray",..I think I even seen it once,..FOR REAL!!!

I don't give any warranty, to many variables for me. To add to what Chuck mentioned, the proximity of other infected roofs can also have an effect on time of staying clean. Although I see the value in it for others, I don't want phone calls from people who "See something up there" and it turns out to be a shadow or part of the contour of the roof that just looks different during different periods of the day.

I give them an expectation of two years and follow that statement up by telling them that it will be more like four years, based on the amount of years I've been watching and seeing. I've never lost a job because I don't give a warranty.

 Same here,,, in fact I have closed more sales because I DONT provide a warranty versus some others here that do, but is not really a warranty, more like a maintenance contract.  I tell the custome to call me as soon as they see the balck streaks returning and we can come back and treat again at a substantial savings over the original treatment.

We went from a two year guarantee to a three year guarantee this year ( our third year in business). I have only been called back once for algae under a upper gutter coming out on a lower roof. Below is a picture of a vacant building I sprayed two years ago. It's still holding up good with nasty algae on the same north facing roof. This quarantee sets us apart from all of the pressure washers cleaning roofs.

Uhm, Maryland is in the SOUTH.  In case you weren't aware.  Tell us more about up North??

Maryland may be considered the south but it has northeast like conditions and honestly i would say its closer to the north than south.

I agree the mason dixon line may say its in the south. But mentality and culuture, is more like the north.

I agree also with Doug & Ray. Plus, part of my sales talk is "you may see someone offering a 5 year warranty, but, try to collect on one and you will see why most of us Florida professional just honestly tell our potential customers what to expect, in reality." "Here in my area, the only businesses I know of who offer 5 year warranties, are actually offering a maintenance contract or they have only been in business a year or 2 and will probably be out of business in another year. I have been in business here since 1989"

95% just say "When can you do it"

 The 5 year warranties helped put many companies out of business, here in Florida. These roof cleaning companies spring up, offer 5 year warranties to try and steal work, then they either go out of business before all the warranties start comig in, OR, they refuse to honor the warranty, due to a little clause in the contract called "acts of God"! LOL, an "act of God" can mean it rained an inch more in August of 2013 then it did in August 2012, and the increased rainfall caused the roof to get dirty faster.

One company who stole a job from me, told the customer his warranty was null and void, because his neighbors driveway was black, and the algae from it spread to his roof!
