Roof in the Rain
Permalink  
 


One of my really good customers is a historic Church in Apalachicola, which is about 2 hours drive from my house. This organization & its members is responsible for THOUSANDS of dollars in business to me annually, so when they call, I jump.

Church just bought this residential home and turned it into the church office. I had a very short window to do this job and it was raining on the day I made it to Apalachicola. Not very convenient to pack up and return another day after an investment of time, fuel and labor, so I decided to try out cleaning anyway.

I was delighted with the results of the cleaning, it did just fine with wet shingles. I waited until the eaves line quite steadily dripping rain water, then would spray, then a short downpour would come and I would stop and I'd wait a little longer and pick up where I left.

Process took much longer (2 hours) due to stopping and starting. Used a 40% SH mix and one gallon of Green Wash. Used 60 gallons of solution total ( made 75 gallons, thinned the leftover down to 15% and softwashed the house).

Roof was sprayed twice to provide these results. I'm just happy to know roof cleaning on a rainy day is now an option.

One thing I did notice is that the hotter mix with green wash ERADICATED the lichen, it simply rinsed off with the hose. Don't know if this was due to GW or just my overly strong mix, but I liked the results.

Hey Ray,..nice job! I've done roofs in light rain but was never comfortable enough with it to disregard the weather in future scheduling. The mix starts running off as soon as it hits the roof, and the less thirsty the growth is the less of the product it is going to absorb. So between run off and a wet roof,..the results may be harder to achieve and to be able to set as standard results. The lichen most likely came of easier due to the saturation or softening of the growth from the rain.

Another great job! That Lichen looks like it was in tough spot for the rain to hit anyway so maybe rinsing then was a good idea so they wouldn't call you back.

Yeah, that lichen was under the gable and out of the rain...doubt it would have ever naturally rinsed off.

Job looks good. Did you use a stronger mix because of the rain. Was the rain more of a mist or a steady rain. I was under the impression roof cleaning couldn't be done in the rain, I'm glad you posted this

Brian, it alternated between a heavy mist to a downpour. With the mix I used I was okay to spray as long at the eaves weren't steadily dripping. Had to stop and start a bunch.

Ray, thanks for the post. It's good to see posts about different circumstances that come up during roof cleaning, and how it was handled, and how the cleaning worked. We all can learn from each others post.

Roof, looks great. Very nice to know the roof can be cleaned during the rain.

I almost like it better when you clean roofs on a rainy day.  It does not rain hard usually so wait it out.  Minimum worry about over sray or plants.  Just pump up the strength a bit.
