    New Stone Coated Metal Roof by Cal-Pac Roofing
    Justin W.

    We purchased our house coming up on six years ago. During the inspections, we were told we had between three and five years left on the existing roof. As those years passed by, I noticed more and more exposed fiberglass edges when pulling into the driveway. Gutter cleanings resulted in literal buckets full of granules coming off of our composition roof, now on its last legs. The rainy season was coming and we had a new baby in the house, so it was time to get this roof project going. After spending more time than I want to admit researching the best roofing option, I decided on a stone coated metal roof. Standing seam metal roofs are great, but, one wouldn't fit our neighborhood or our budget. A stone coated steel roof is a great way to reap the benefits of a lightweight, watertight, energy efficient and incredibly long lasting metal roof at a lower cost than a standing seam roof. You have to go into this knowing it will be more expensive, but a stone coated roof should easily outlast a composition roof two to one, without being twice as expensive. OK, time for quotes. This part was pretty easy as there are only really two companies that do stone coated steel roofs. Honestly, both quotes were within a few hundred bucks of one another, but Cal-Pac's online reputation and Tom's straightforward demeanor sealed the deal for me. I also got a few quotes on a regular roof and decided that the benefits of a stone coated steel roof were worth the difference in cost (about 40%). We're planning on staying in our house a long time, so, the stone coated roof felt like an investment in our home. You'll have the option to leave your existing roof in place or install the stone coated on top of it. We opted to remove all of the existing roofing, repair some of the decking and go with the water proofing / insulating materials Tom recommended. Our old roof was off and hauled away, repairs were made and the waterproofing barrier was down on day one. Unfortunately, there were some material delivery delays out of anyone's control due to some warehouse change-ups, but Tom kept us in the loop and our roof decking was left with a water resistant barrier until the materials showed up a few days later. In only a couple of days, our roof was complete and signed off by the City. The installation crew did a fantastic job. Once done, everything looked great. Several of our neighbors have asked about our roof, noting the 3D look it has, many not believing it is made of metal. On hot days following the installation, we noticed a difference in the house thanks to the insulating properties of a stone coated metal roof. With some additional soffit vents installed as part of the roofing project, our garage and attic are notably cooler. Fast forward a few months and the longest period of heavy rain with the new roof has just passed, and there have been no leaks, no problems. We've dealt with several contractors for a few projects over the last few years and I can say, without hesitation, that dealing with Cal-Pac roofing, Tom and his crew was the best of those experiences. Everyone we dealt with from Cal-Pac was upfront, trustworthy, prompt, knowledgeable and dedicated to doing a great job installing a great product.

    We just got a new Boral Still Stone coated roof, Barcelona-style, installed by Cal-Pac Roofing contractors in July 2020. We are extremely happy with the outcome of our new roof. Tom Sparling, owner of Cal-Pac Roofing, provided a very competitive estimate. We felt very comfortable working with him. He was honest, promptly responsive, and very understanding. Throughout the project, if we had any concerns, the very next day he had solved them. His flexibility spoke volumes -- he worked with us to schedule their work around a parallel project of painting the exterior of our home. I can't say enough about his patience. Sal, the roof installer, was highly skilled, efficient, and a very hard-working professional. He was very helpful in assisting us with fixing a few dry rotten woods on our request. Sal and his colleague cleaned up after themselves every day, made sure things were neatly tidied away, and left all areas clutter and debris free. The final results speak for themselves. The roof looks great with our newly painted house. We have already gotten lots of compliments from our neighbors about how well the job is done. Due to COVID times, a lot of neighbors and passerbys endorsed what a pleasant experience it was watching their crew throughout their work progress. Tom and Sal were a pleasure to work with. Their sincerity and dedication made us feel confident that they stand behind their product, strong workmanship, and great service. I highly recommend the services of Cal-Pac if you are looking to replace your roof. Thank you Tom for a phenomenal experience. We love our gorgeous new roof.

    Cal Pac replaced my roof last January, and I am very happy with price and quality of work. Before I choose Cal Pac, I had several estimate from other companies, Cal Pac is the cheapest and have better warranty. Tom is very professional and prompt in schedule. They finished my roof in timely manner.

    Roof with roof hooks installed

    We had Tom Sparling and his crew install a SteelRock stone coated metal roof at our house in South San Jose. He was very professional and came to our house to show us how the roofing product works and also suggested the use of the best solar L-brackets to use with this type of roofing product so that you end up with no roof penetrations associated with the solar racking system. Tom even included the labor of installing of the solar roof hooks with the whole system. We had to order the correct number of roof hooks and tell Tom and Sal exactly 1) which rafters to install them on and 2) between which roofing tiles. I made a couple of drawings that showed this clearly and Sal got everything perfect on the first try so we didn't have to move any roof hooks -- the solar install went seamlessly the weekend after the roof was completed. The removal of the old composite shingle occurred on a Monday and was done in 4 hours. They had the weather barrier on the next day and metal shingles started going up on Thursday morning. The roof was completely finished on Wednesday and it passed inspection with flying colors -- the inspector said: "this roof is going to outlast me, you, and your children". Throughout the process Tom and Sal were responsive via text and email and a pleasure to work with. There were no unexpected cost overages or delays in the install so I couldn't have asked for more. I am glad I went with them and glad I will never have to think about the roof as long as we own the home!

    Hello, I am considering buying an older home (1969) with a Cal-Pac roof. It needs to be tented but the repair company refuses to cover any damage they say these roofs can not be walked on and damage easily. Of course we are very hesitant. Input?

    I agree w/ Mary Ellen. Call Cal-Pac Roofing's owner, Tom Sparling. He would recognize what kind of roof you have, and he could probably account for its aging (although I would assume that your current roof is not the 1969 original). We just got a… Read more

They also helped us replace an extensively damaged flat roof in a very short amount of time. The owner has been in this trade for over 20 years so they have done a variety of jobs and a variety of buildings. It's good to know a small business like this has the experience and knowledge to make a solid product - one that they put their name onto.

In response, they blamed one of their employees for leaving and had no idea about the project despite the whole team cc'd on every communication since the quote.

He was curt and disinterested in his responses, offered no apology, and showed no consideration for the time and effort wasted on our end. When we asked for reassurance on the revised timeline and quote Geovanny simply told us that it was "not up for negotiation." It is doubtful that Q7 is interested in or values your business. With service this bad before they started work or got paid it is hard to imagine they would even pretend that you exist afterwards if an issue were to arise. EDIT: See business owner response below obfuscating rather than simply offering an apology and solution to ghosting the project without a single attempt to reach out about it. Evidence that this was not a one time accident but just business as usual
