How to Clean a Roof with Wet and Forget
LESLIE: Now we’ve got David in Florida on the line who’s looking to clean a roof. How can we help you?
DAVID: Well, actually, life was wonderful and then we moved to Florida where there’s too many homeowners’ associations.
TOM: OK. I guess you’ve been cited for something, huh, David?
DAVID: Oh, more than one thing.
DAVID: But one of the things that was always annoying, not to mention the expense, is the issue of washing the mold, fungus and/or whatever off of the roof which, in this particular (audio gap), is a concrete roll-tile roof and so on and so forth.
DAVID: And it seems that all – when you call up the roofing manufacturers, they are all recommending that you don’t do anything. Once the roof is installed, you don’t walk on it, you don’t look at it, don’t paint it. Just leave it alone.
LESLIE: And if you paint it, you can only paint it this color; don’t even think about this other color because we’re on you.
DAVID: What is the deal about that? Should roofs – and does it depend upon the type of roofing coating? Like if you go to composite versus concrete shingle or actual clay tile, should those be pressure-washed or not?
TOM: Great question. Will pressure-washing a roof damage it? And the answer is yes if you are too aggressive with it. It’s OK to rinse your roof off; it’s not OK to sort of blast this algae off.
I would suggest that you go to WetAndForget.com and take a look at this product. This product, once you apply it to the roof, it will start to degrade that algae and clean the roof on its own. There’s a lot of photos on the site, too, of before-and-after roofs that have done very well with just putting Wet & Forget on it. Literally, you wet it down and you forget it, walk away and then, in the next couple weeks, you’re going to start to see that algae just sort of die and fall off and not come back.
DAVID: Wow. That is really good because there have been a number of people that – obviously, you do the pressure-washing with 4,000-psi rotating whatever…
TOM: Yeah. Well and they try to sell that to you, right? It’s kind of like, “Well, if this guy has only got a 2,000-psi machine, we’ve got a 4,000-psi machine.”
The thing is, it’s not how much muscle that you have, it’s the finesse, it’s the touch. It’s using chemistry to your advantage and that’s why you want to use a product like Wet & Forget. And you may find that you’ll use it on your sidewalks and on your siding, too.
Listen, go buy enough of this stuff to try it out. See what happens and let us know how you make out. But I used it on my house; it’s been great.
LESLIE: Mm-hmm. And give it some time. You’re not going to see the results the first day; you need a couple of days, a week. And I mean if you go to the website, you’ll see that they used it on the Sydney Opera House, on an aquarium in Florida: places that were just completely dealing with humidity and moisture and mold growth. And to be honest, cleaning those surfaces were a giant pain in the you-know-what, so they applied it for the heck of it and it worked.
DAVID: Oh, excellent, excellent. That sounds really good. Yeah, because the only other alternative – we had another competitor who used to put the good old sodium hypochlorite all over the roof, which did get the algae. Unfortunately, it also gets the plants below it.
TOM: Yeah, right. Kills everything.
LESLIE: And that doesn’t actually kill the mold and stop it from coming back. Yes, it gets rid of it but the spores are still there and they’re going to grow back.
DAVID: Alrighty. Well, that sounds excellent. Thank you so much. I will call you back. Thank you so much.
TOM: Alright. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
