If not done correctly, applying chlorine at an angle can eventually damage the roof and the felt lining under the shingles. And, diluted pool chlorine wasn’t getting the job done. It worked for a while, but needed frequent applications. Eventually I hired someone who got on the roof and sprayed undiluted pool chlorine directly on the shingles. He knew what he was doing, protected the tiles from oversaturation, covered my vegetation and took two days to do the work. One guy working on his own. The roof looked great when he was done, but six months later it’s dark again. My HOA is now advising me to have it pressure cleaned.
Okay, I looked on Angie’s List and the Home Advisor websites and got some leads, but I always research the companies on my own, checking on the Better Business Bureau websites and reading reviews carefully. I was impressed by two of the companies and asked for an estimate. Before they responded, they first looked on Google Earth to get an idea of the size of the roof, the type of tile, and other information from the satellite view so they could give a better estimate. One company gave me a price over the phone and the other came out to my house to talk to me. They were both in the same price range, but offered different services. The first company just did a pressure wash. It gets immediate results, but little else, because new algae just grows back. The second company recommended a low pressure wash with a combination of chlorine, algaecide, TSP and a detergent. This was supposed to give better results and last longer than just pressure cleaning. Made sense to me, but I was not impressed with the individual who was going to be doing the work. After all, the results are largely determined by the guy on the roof, not just the chemicals or the hype.
After getting more informed and checking more reviews, I contacted Marcus at Crimson Clean. We talked on the phone for about 20 minutes as he helped me understand the different approaches the other companies were taking and now Crimson was different. He was passionate about his work and the training he received from another professional. He explained the best way to get quick and long-lasting results. I really picked up on “long-lasting” and was impressed that they offer a two-year warranty. You never get results like that with just pressure cleaning. After understanding exactly what was going to be done, I asked Marcus for an estimate. He was the high bidder, but I learned long ago that price and value are not the same thing. It took some soul-searching, but I was impressed by his friendly and professional attitude. After having been disappointed with other individuals, I decided to go with a professional company who stood behind their work. I knew Marcus was the guy I needed on my roof if I wanted to get the job done right.
Here is where work ethic comes in, because the weather was not very cooperative, but the job had to be done (mostly at the insistence of the HOA). But, Marcus was up to it. While other people have arrived in open pickup trucks or their own car, Marcus showed up in a nicely painted work vehicle with all the tools, hoses, applicators ladders and accessories. It clearly indicated he was a dedicated professional and here to do a great job.
And he did. Despite intermittent downpours and sunshine, he worked tirelessly, although drenching wet, to clean every inch of the roof and the side tiles. Areas that needed special attention were hand scrubbed to assure the algae was removed. Our shrubbery and hedges were covered with plastic sheeting to protect them from any runoff and a constant spray of water was also applied to dilute any pooling of chemicals. The downspouts were covered to prevent chlorine from saturating that area. The gutters were cleaned and remnants of the red coloring from the cleaned tiles was washed away. Often Marcus was on the roof in the rain paying special attention to areas needing more work. He was unstoppable doing a good job.
The entire roof was treated with a chemical fungicide and algaecide. The result was a clean roof with the algae killed and a preventative which will keep it from returning. Three for the price of one.
When the rain was too hard to continue work, we got together to talk more about how to keep my roof looking better for a longer time. Marcus explained that algae often starts at the lower edges of the roof and works its way up. So to prevent a reoccurrence, I could also treat the lower edges and roof corners with an algae inhibitor myself. I will probably use a product called Wet and Forget, which my neighbors recommend. It will be easy to spray this around the edges and lower roof tiles to prolong, the results of the cleaning. But, with a two-year warranty, I’m fairly certain the products Marcus used last a long time. It will be nice not to worry about a roof every few months and I’m sure my HOA has better things to do.
