I have a small house and I waited about half a year before they could come out, but it's worth the wait. I initially contacted them from yelp because they are local in altadena, and the owner Felipe came out very soon and gave me a few estimates on different options to go about replacing the roof and the different assemblies. He seems like a trustworthy and likeable guy. I have a very flat pitch and the house is mid century with open beams, so there's no insulation and it gets extremely hot whenever the ambient temperature is above 80F. I received the estimates within a week I believe. By then it was the middle of summer so I decided to wait till it cools off a bit before getting the roof project done. When I asked them about availability in the fall, I was surprised to find out they are still several months out. Then winter rolls around and the rains started coming. Even though there's no leak yet I am concerned that I will get leaks soon, because the previous strong wind blew off the asphalt shingles (which is a wrong system anyway) and I started to see a lot of dry rot on the eaves and water damage from the last winter storm. There was this week which we had a good 3-4 consecutive days of rain, and I called Felipe and his son came out the very next day, in the rain, to put up plastics on my roof. They didnt even request a deposit or payment of any kind. The plastic made me and my wife feel a lot better during the winter rains, and we are very grateful for this gesture. But eventually the strong wind blew off the plastic and we finally got our first slow leak near the fireplace. Thankfully we got through winter without more leaks in the house, and when spring rolls around Rivas roofing finally found a window to fit my project in. On the first day, Mr Rivas covered up my living room with plastic (very nice gesture) to minimize the amount of debris during tear off inside the house. I cannot tell his age exactly, but he is an old man and he went up to the roof with the young guys to do the tear off himself. I was pretty impressed with how hardworking he and his crew is. Over the course of 2 1/2 days, the guys always show up on time, clean off the areas around the house at the end of the day, working non stop and always willing to answer any questions that I have. They also replaced the damage wood and fascia boards without additional cost. I was extremely happy that the project was done in just 2 1/2 days, not to mention the huge improvement that i can feel immediately. I only made payment after the job is done! all the while they didnt request any deposit, payment or upfront fees for materials etc. The highly reflective roof and radiant barrier is amazing. Generally on a 80-90F day, I cannot live without the AC on past 1pm (indoor temp about 84F). On a 95-105F day, the house would have AC on the whole day and the temp would still linger at 86F. After the roofing replacement, wow...the ceiling feels cool to the touch! It hasnt really gotten hot yet but I have been turning on the AC in the past 2 weeks already, because my house would be 83F while the house outside is around 90F. With this new roof, I dont feel the need to turn on the AC at all since it's a cool 70-74F throughout the day. I am pretty sure I still need to rely on AC when the 105F day comes around in the summer, but I am excited to see how much the cooler house is with this new roof. I can already see a huge improvement. Despite the long wait, the experience I had was a crew of hardworking guys who knows what they are doing...Felipe and his son are genuinely nice people and takes pride in their work. The price is fair and the duration is short, making the least disruptions to my day to day life, and it's great to know we have such a great company so close to your home...that you know you will be taken care of in the future should you need any roofing assistance. I will certainly ask them for help again in my future homes read more
