"This roofing job started off bad and continued to the finish. I wanted a professional with a few requirements. Be careful of original structure as it is prefabbed. The workers punched twelve holes in sheeting removing old roof material, requiring sheeting overlay. I requested that roofing nails not protrude through roof in patio area. They were protruding through the entire area. They left refuge sitting on the side of the driveway until I asked to have it removed. The one-week job turned into a two-month Odessey. The job was obviously a side job, piece-mealed together with little supervision little supervision. I am not confident the roof will not fail. prematurely fail. "

"My roof was leaking around the fireplace and my gutters needed replacing but I was hesitant to hire someone as I didn’t know who was reputable. I noticed my neighbor who had roofers repairing the area around his fireplace and I got his roofers names. His roofer was Jorge Maldonado (415) 424-1274. Jorge does roofs (replacement and repair), deck repairs, siding repairs, fencing repairs and exterior painting. I had him check my roof and he patched up the area around the fireplace, explaining what he was doing each step of the way. He also sealed all the roof vent pipes. I also had him replace my rain gutters and he disposed of the old ones. I was happy when Jorge said that my roof did not need replacement at this time, that it was good for about 5 more years. Jorge and his crew did an excellent job. Jorge explained each step of the way and was clear on the price. The workers arrived on time, worked efficiently together getting the job done, and cleaned up after themselves. After Jorge did my roof, another neighbor had him do partial rain gutter replacement for her home. I was really pleased with the job he did and plan to contact him when my roof needs replacing or my side fences. Recommend him to anyone who wants an excellent worker!"

"Our shiplap wall used to look awful. And I can’t count how many times painting companies knocked on our doors and asked if we want to paint the house. We always turn them away and tbh it can be really annoying. But what made us go with Keith? One day, Richie knocked on our door, and before I could say anything to reject him, he already disclosed his whole lineage - his father, his grandfather were all in the business. He made a great first impression so when we finally decided to paint the house, I made an effort to find their business card and gave them a call. The whole estimation process was so smooth and the price is fair in this market. Richie was very professional and gave us updates each step of the way - we know how many workers will be onsite at what time, and what they will do the next day and at approximately what time they would finish the day and leave. And the actual painters (very sorry we didn’t get their names) were very respectful to the place, and they are efficient and gentle! They rarely spooked my fearful dog even! I have a lot of flowers and plants planted against the wall, they managed to work around all of them without damaging anything, compared to the previous painters, where we could see they just directly left patches unpainted behind the plants. After everything was done, they cleaned up meticulously and put back everything they had touched. I’m really impressed! We will definitely recommend Richie and his crew to anyone who needs a fresh look on the house."

FAQs for roof sealant application projects in San Francisco, CA

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
