LESLIE: Roy in New Hampshire has a question about cleaning roof. What can we do for you?
ROY: Well, I was listening to your last episode and I was thinking, where my roof is dark and I do have lichen patches …
ROY: My concern is if I get up there and I splay it – spray it – with the bleach-and-water mix, that I may leave spots on the roof. Is that the case or do you know?
TOM: You mean you’re concerned you’re going to have bright spots or dark spots when cleaning roof?
ROY: Bright spots.
TOM: Because it’s really clean there and it’s not as clean elsewhere? I think that is potentially an issue because the roofs are going to darken over time. And you may have a little bit of moss or lichen growth on one side and then you may have a lot more on the other. So if you kind of try to spot-clean it, it may look somewhat uneven and streaky.
There’s another way that you can go about cleaning roof that’s going to be slower and more transitional. And it’s a product called Spray & Forget. Kind of does the same thing but it’s a little bit easier on your lawn and your plants. And you basically apply it to the roof and then over the next coming weeks, it starts to basically kill all of the growth that allows the mold, the moss and the mildew and the lichen to kind of take hold. And then once it’s dead, it starts to lose its grip on the roof and then wash off. And so, if you did that once or twice a year, that might be another way to do it and it wouldn’t be quite as dramatic as just a bright spot where it happens to be really bad right now.
ROY: You said Spray & Forget?
TOM: Spray & Forget, yep.
ROY: Awesome, awesome. That was my concern when I listened to the episode. I was thinking where the roof was dark, I would leave those spots but …
TOM: Yeah. I think that will give you a much easier – a much more even transition and you’ll really like the way it works for cleaning roof.
ROY: That’s great. OK, I will. Spray & Forget. Alright. Thank you so much. I appreciate this.
