Posted on Ginny HallnerTrustindex verifies that the original source of the review is Google. I highly recommend Ascent Roofing Company of San Diego for roofing services in the San Diego area. They recently completed a full roof replacement on our home and we appreciate the skill and professionalism afforded to my husband and me. They arrived on time for appointments and maintained a clean work area. Communication was excellent, with updates and answers to questions. The workmanship was exceptional. High-quality materials were used, and attention to detail was given during the installation. The project finished on time, and the pricing was competitive and reasonable. Their professionalism, quality of work, and customer service are noteworthy. We were referred to the company by a neighbor and they were equally happy with the work. Thank you Isaiah & Josue Macias and your team for a job well done! Ginny Hallner, 7785 Madrilena Way, Carlsbad, CAPosted on Bovey RainguttersTrustindex verifies that the original source of the review is Google. Ascent roofing is top tier. Family-owned and operated. They are the best and most efficient roofers in San Diego.Posted on Lo SMTrustindex verifies that the original source of the review is Google. This review is a long time coming as it’s been several months but I have to say how amazing Ascent roofing has been for our home and family. We had a consultation with Josue who took the time to address our concerns and patiently answer the million questions I had. The installation crew was professional, friendly and worked fast. Saira helped navigate through all the paperwork and explained everything so I felt confident before signing my life away on such a large investment. On top of that, the price was very competitive, especially living in such an expensive city. If you’re looking for a good, reliable roofing company with family values, do not hesitate to give these guys a call and see for yourself!Posted on Brett PerkinsTrustindex verifies that the original source of the review is Google. Ascent Roofing is the best home improvement experience we've ever had. The communication was great and the roofing crew was fast, efficient and flawless. Pure professionalism from start to finish. 6 out of 5.Posted on Thomas PrimoschTrustindex verifies that the original source of the review is Google. I recently had Ascent complete a full reroof of my 2 story home. My home is about 3400 square feet with three separate roof sections and a solar system. From the first meeting they were great. After discovering a leak, I scheduled Josue to provide estimates on fixing the leaking portion or doing the entire roof. The day of the estimate I had a conflict arise and Josue easily rescheduled for the next day. He arrived on time and from the first conversation I found him very pleasant. His pricing was very competitive. All their references checked out and confirmed the competitive pricing and their satisfaction. Once I signed the contract, within hours I was contacted by Isaiah who was the job scheduler. I was impressed just how quickly he called me to schedule the job for about a week in the future. This was important as there were a series of storms reported about a two weeks out. As promised his full crew arrived at 7am on the start date and began the disassembly. Every day for about a week (except Sunday) a full crew of 5 was on my roof. They were all very polite ands courteous to my wife and kids. They worked everyday from 7-4ish. Everyday, before they left, they made sure to clean up the work area around the home. Isaiah provided me with nightly reports of the progress his crew was making. He explained what to expect the following day...and he was right every time. As part of the job they had to remove my solar panels. They were reinstalled in the same working order as before the job. Isaiah promised my roof would be water tight every night just in case the rain came early. The job was completed on time and 2 hours before a 4 day rain storm. There were no leaks! I have had poor experiences with prior contractors where only partial crews would show up. So I was impressed when everyday a full crew was present. I commend Ascent for having the full crew show up and finishing the job on time. Another point I want to mention is their support team is stellar. Ascent was extremely helpful pulling permits from the city of San Marcos. Their patience dealing with the city's bureaucracy was amazing. To sum up, they are friendly, honest, skilled and on time! I definitely highly recommend them.Posted on Matthew RitzmanTrustindex verifies that the original source of the review is Google. Bought my first house and my inspector let me know that my roof was end of life. There were also over 20 solar panels on the roof making this not a super simple replacement. Isaiah was my project manager and was absolutely superb. Other Roofers told me the project would take 5 days, Isaiah and his team had the roof completed in 2 and done very well for a very competitive price. The lead on the second day gave me a walkthrough upon completion to make sure I was happy with the work. There was a slight hiccup reconnecting the panels (one panel was not generating power) but without question Isaiah had his solar team back out working until they solved the issue. I will be recommending Ascent to anyone I know looking for a roof.Posted on Steven LewisTrustindex verifies that the original source of the review is Google. Ascent Roofing has been professional, courteous and efficient from the very start. I am completely pleased and happy with the new roof. The team showed up on time and completed the job in about 2 days. They even came back out at a later time to fix a little issue that needed fixed. I would recommend Ascent Roofing to others who are looking for getting their roof replaced.Posted on andrea wellsTrustindex verifies that the original source of the review is Google. From the first call to the completion of the roofing, the level of professionalism was outstanding. I had questions along the way and Isaiah and team were incredibly responsive and kind. I was kept up to date on findings during the roof replacement. I highly recommend Ascent Roofing.Posted on Catherine PersonTrustindex verifies that the original source of the review is Google. Our 60’s townhome’s roof was fifteen years out of warranty and had developed leaks in six areas. We sought multiple roof bids based on our HOA’s new set of architect plans, to ensure that bids included all the same components. We chose Ascent Roofing and are very happy with their work, the staff, the price. They went above and beyond and provided excellent communication from the first phone call with the support staff and estimator through final billing. Owner Carlos Alfaro personally supervised the construction project. This is a family owned business that takes pride in their work Thank you to all at Ascent!Posted on Jared McElhanyTrustindex verifies that the original source of the review is Google. Ascent did an excellent job replacing our roof. Great communication throughout the process. Highly recommend.

Frequently Asked & Questions
How do I know if my commercial roof needs replacement?
If you’re dealing with frequent leaks, visible damage, or rising energy bills, it may be time for an entire roof replacement. As the roof ages, it can become less effective at protecting your building, so it’s important to stay on top of any signs of wear and tear.

In San Diego’s sunny climate, TPO, shingle, and tile roofing systems are great choices. These materials are durable, energy-efficient, and resistant to UV damage, making them perfect for our hot, sunny days and occasional rainstorms.
How long does a commercial roof replacement take?
Typically, a commercial roof replacement can be completed in 1-2 weeks, depending on the size and complexity of the project. We’ll work with you to ensure minimal disruption and get your new roof installed as efficiently as possible.
