We make sure that we notify him in advance of any kind of hazards, as part of workers' compensation insurance. Suggestions that we always talk to our clients and do a walk-through around the property prior to starting the project. If we find any electrical hazards or any kind of dangerous hazards that we need to actually install pedestrian canopy scaffolding, we definitely do that. Not only for precaution, but it's also a building code by the City of San Francisco that we install pedestrian safety canopy, and we do that with all of our projects. What we do is we educate our clients from beginning to end before we start. I ask for all their concerns, and I'll ask them to always have a list of questions ready about everything that they're concerned about or they're curious about. And during the whole process, what we do is, while we're working on the project, we take pictures and we let them know of certain penetrations or other issues that come up and that need replacement or other options that they could go about with all the other materials that there is. And been doing this for 30 years, we give them different options that they could choose from, such as if there's flashing issues, there's copper, stainless steel, and there's galvanized, and of course, there's price differences on those. So we educate them on pros and cons of the type of metal that they use and how long it's going to last, and material-wise, of course, there's warranty differences. Some of them say lifetime, but it's actually a 30-year warranty in the previous material samples, which could be also 50-year warranted, but now they're all identical and they're all lifetime warranted. So what we do is we explain to them in detail the thickness of the sizes and let them know what would be the best method to go forth as far as composition shingle-wise. Sometimes you get the 30-year shingles that's more than adequate; some people go for the 50-year shingles, and you don't need to do that because after about 25-30 years, the surface of the shingles will start to deteriorate, and customers don't like the look of it, so they end up changing it prior to the warranty has expired. So I always talk to them and let them know that it's not necessary to go with a higher warranty. It's okay to go with the lower one because they're gonna replace them eventually. I got into this industry because of my uncle. My uncle still owns a roofing company, so now he's retired, and my dad was also into it as well. Unfortunately, I was able to learn this trade early, and when I turned 18, instead of going to university, me and my dad opened up our own roofing company, and that's 32 years ago, and I've been doing it ever since. Unfortunately, my dad passed away about 80 years ago, and I had to open up a new one of my own, and I've been Diamond Certified ever since, and I'm very proud of it. In this trade, I wanted to learn a trade, I wanted to be skilled at something, and when I started to do roofing, I got to be honest with you, it was one of the hardest things I've ever done in my whole life. Physically demanding, the hours, it was just very, very hard. I was tired every evening; it was hard for me to get up the next morning because my body was just broken down. But after about a couple of months, my body got used to it, and I realized the arts and crafts of the trade. Before you get in it, we take before, during, and after pictures, and when you take the before picture, and it's very ugly, then during picture, then after the fact, it becomes like an art to me. You see a before and after picture; it's very satisfying. And also that I got really skilled at this installation of roofing products, since I've been doing it over 30 years. It's an unbelievable satisfaction after each and every project is completed, and you see the satisfaction on your customers' faces. I gotta say it's the satisfaction of customers when I see the happiness in their face. It just makes me want to do this even more, because I make sure that every single one of my customers is satisfied. What I tell my guys at work is if there's any issue at the job site and if there's anybody that comes out and they're angry, I teach my guys to just don't say anything, listen, and at the end of the conversation, there should be only one question you should ask the customer: "What can I do to make you happy?" And that's it. That's my attitude towards our company's model, and that's only that comes for the project owner but also the neighbors that come out and complain about noise or debris falling or whatever they have an issue with, and we attack that issue asap. It is taking our time with the project. We don't rush. I don't rush my workers. We are very detail-oriented because I feel that roofing, number one, would be to waterproof, to make sure the water doesn't leak, but it also has to be uniform and it has to look good even though you can't see it maybe flat roof you can't see single roof you could definitely see. But neither place that you could see or can't see, I do the job identically. There's absolutely no cutting corners. Everything has to be detail-oriented. If it's not uniform, I tell my guys to rip it off and do it again. I don't care if I lose money. More important is quality workmanship. Quality workmanship equals to customer satisfaction, and there's no doubt about that that's also part of my success.
