Roofing Services We Provide In San Marcos

From routine repairs to full replacements, Dils Roofing handles every type of roofing project in San Marcos and the greater San Diego area. Every job is backed by our four-generation commitment to quality craftsmanship.

Residential Roofing

From established San Marcos neighborhoods to new construction in San Elijo Hills, we provide full roof replacements and upgrades built for inland heat and sun exposure. Every residential project includes a thorough inspection before we begin.

Residential Roofing

Expert installations for retail, office buildings, and industrial properties throughout San Marcos and San Diego County. We work around your business hours to minimize disruption and deliver on schedule.

HOA & Management

Reliable maintenance, repairs, and full replacements for property managers and homeowners associations across San Marcos. We understand HOA approval processes and can help coordinate documentation and timelines.

Roof Repair

San Marcos’s intense inland sun and seasonal Santa Ana winds wear on roofs differently than coastal San Diego. Our repair crews specialize in leak detection, flashing replacement, and storm damage repairs that restore your roof’s integrity without a full replacement.

Solar Services

Specialized solar panel removal and reinstallation during roof replacements, a critical step that many San Marcos homeowners overlook. We manage both the roofing and solar work to ensure zero leaks around panel mounts after reinstall.

Roof Inspections

Detailed forensic roof audits for real estate transactions, insurance claims, or preventative maintenance. Our inspection reports are thorough, documented, and delivered promptly, ideal for San Marcos’s active resale market.

The Inland Challenge

San Marcos Roofs Face Conditions Most Contractors Don't Understand

San Marcos’s position inland from the coast creates a different set of roofing challenges than San Diego’s beach communities. Intense UV exposure, wide temperature swings, and seasonal Santa Ana winds require materials and installation techniques that contractors used to coastal conditions often overlook. Getting this wrong shortens your roof’s lifespan significantly.

Intense UV Exposure

San Marcos sees more direct, sustained sun than coastal San Diego, and standard asphalt shingles degrade faster under it. We recommend tile, upgraded shingle systems, or high-reflectivity materials built to handle inland sun without premature granule loss.

Thermal Cycling

Hot days and cool nights cause roofing materials to expand and contract repeatedly. Over time this stresses fasteners, seals, and tile, leading to cracking and loosening that isn’t always visible from the ground.

Santa Ana Wind Events

San Marcos sits in the path of seasonal wind events strong enough to lift shingles and dislodge tile. We install with wind-rated fastening methods and recommend a post-event inspection after any major Santa Ana activity.

Attic Heat & Ventilation

Inland attics run hotter than coastal ones, which can shorten the life of roofing materials from underneath if ventilation isn’t properly designed. Our installations prioritize airflow to reduce heat buildup and protect the roof deck over time.

Dils Roofing knows their business very well. Very professional and provide high quality service. Ryan was our project manager and communicated all aspects that needed to be done before, during and at the end. We had our 35 year old roof updated in 2017. The team was on time every day and cleaned up after themselves. Now we are in the middle of selling the house and Ryan provided us another inspection so that the new owner can feel confident that the roof is very sound and has many years ahead.

Working directly with Ryan (owner) was an absolute pleasure. His upfront and transparent communication got us to a beautiful final result without any hiccups. Everyone I was in contact with at Dils had a humble confidence that told me I was in the right place. I never felt like I was being sold, instead I was educated enough to make the right decision. 10/10 would recommend.

We suspected a roof vent leak at my mother's home. Our HOA sent out Josh, the Project Manager from Dils Roofing to inspect the roof. He not only informed me that it wasn't the roof leaking but helped me troubleshoot the problem. After his recommendations, I was able to discover the source of the leak. I was super happy! He made a bad situation pleasant by being helpful and on time. If I ever have a roofing problem again, I would not hesitate to use this roofing company again. Thanks again Josh!

We have been dealing with Dils Roofing since around 2003 including 3 roofing projects. It is a pleasure to deal with a true family run san diego business and to see all the same attributes continue over all this time. As always this project was a huge success. Ryan came out in a timely manner summed up what we needed, gave me options and then scheduled the work. It was all seamless.
Joyce A.★★★★★
I've had Dils Roofing handle repairs on our home since 1998. They are competitively priced, and the quality of work is a cut above any other roofer. In the three repairs they've done, their crew is professional and courteous. A lot of repair guys "skip" and take shortcuts. Not Dils. They do it right the FIRST time, point out any concerns they come across, and even clean up after themselves. I highly recommend Brent Dils & his staff. The best San Diego roofing company.

Dils gets 5 Stars for their work and professionalism and is my go to San Diego Roofing Company. On time, high quality work and the entire crew was pleasant and completed the job on time and left my property in perfect condition. I particularly appreciated their attention to detail on the roof and roof tiles. They even touched up the paint around the roof tiles. I highly recommend Dils.
Robert I.★★★★★
After we identified a roof leak on our home, we reached out to our friends and neighbors for recommendations for a good roofing company. We received a recommendation for Dils Roofing. We immediately contacted them and got an appointment scheduled for an estimate. Ryan Dils came out, on time, and gave us an estimate. We paid a deposit and the rest is history. From beginning to end they did a great job. If you ever need any roofing work done, we highly recommend them.
Laurie D.★★★★★
Dils Roofing came out to inspect my older roof which needed some attention. They provided genuine service and re-assured my concerns. They offered temporary maintenance solutions until I am ready to replace my roof entirely and educated me on proper roof care. I will be contracting them for some necessary fixes in the meantime! They were also on time and easy to communicate with. The best San Diego roofer in town!
Joanna G.★★★★★
Dils Roofing did several repairs on our roof. The roofers completed the job in 3 days and did an excellent job of cleaning up the site at the end of each day. I highly recommend Dils Roofing for any of your roofing jobs. They were very responsive. Best San Diego Roofing Company!
Lynda B.★★★★★
Dils was a first class professional outfit from start to finish -- we had a small roof leak -- they came out to inspect and give an estimate -- which they explained very thoroughly and was fairly priced -- we signed a "fixed rate" contract and the work was scheduled and completed timely -- and in a very professional manner by an experienced roofer. It has rained twice since the repair was done -- and the leak is fixed. Thank You Dils !!!
Robert L.★★★★★
Dils Roofing was very flexible and willing to listen to why we only needed a repair. The work was done on the scheduled dates and performed professionally. There was no interference with my business during the repair process. No debris was left behind. My inspection of the roof afterward, revealed the repair had been done exactly as stated in the contract. We were rained on the following weekend and now there is no more rainwater in my coffee pot! Thank you, Dils Roofing
Daniel P.★★★★★
Just got a new roof from Dils Roofing! The workers were at my house in San Diego bright and early each day and efficiently and professionally completed the roofing. They cleaned up around the house at the end of each day and courteously responded to our questions and inquiries. I loved the little magnetic box they used to pickup nails and screws that were on our driveway at the end of each day. I would definitely recommend Dils Roofing to anyone needing a new roof!!!!
Sylvia F.★★★★★
The overall experience was just what you'd want from a San Diego roofing company. I now have first hand experience that Dils is the real deal. They know what they are doing and do what they say they will do. I am very happy with their work and overall experience. All their personnel were polite, capable, and professional. I'll use them on my next roofing project.
Brock S.★★★★★
Dils Roofing have done an amazing job, rebuilding the roof on our house, Dils Roofing also went above and beyond in helping us get a Solar System installed. We are truly happy with the installation and performance of everyone involved, totally top notch! Best San Diego Roofing Co
Edward F.★★★★★
Dils Roofing was amazing to work with from the initial inspection to scheduling to follow-up. Honestly, this is the first San Diego roofing company in a long time that called me after the work was done and before the bill arrived to see how the job went and to ask if I had any questions or concerns. Dils was also 15% cheaper than the other two companies that bid the same repair job. Workers showed up on time on the day of the service and completed their work in a timely manner. Best of all, they cleaned up after themselves. I definitely enjoyed my experience with Dils Roofing.
Jeffrey P.★★★★★
Dils Roofing is great. Easy to set up an appointment and they explained everything that needed to be done to me very well. They came to the house in San Diego on time and worked quickly.
Kyle S.★★★★★
33 Years ago Dils Roofing installed my roof in San Diego when I had the home built. So when time for a redoing the roof, we hired Dils Roofing again. They were outstanding. Impressed on how they worked on the repair needed and the roof itself. I took pictures daily and posted on our home web site and neighbors commented on how great it looked. They even did extra per wife's request on trim color. We were very happy with them and they are the best.
Joe M.★★★★★
It can be stressful when you are having work done on your roof in San Diego, but I really appreciated Ryan and his team being so responsive and making me feel very comfortable during the whole process that I had nothing to worry about. This is a great company, very organized and professional. They have been in business for over 35 years and I can definitely understand why with their excellent quality of work, customer service, and overall how they conduct their business.
Michael T.★★★★★
We gave Dils Roofing a call after receiving multiple recommendations from friends in the San Diego area and I'm so glad we did. They set an appointment the same week to inspect our roof and sent over a contract shortly after. The workers that installed our new roof were a pleasure to have around and cleaned up at the end of each day. I'd definitely recommend them to anyone that needs their roof fixed right. Great people to work with.

San Marcos Roofing FAQs

What services does a San Marcos roofing contractor offer?

We provide roof replacement, leak repair, tile and shingle installation, inspections, and maintenance throughout San Marcos.

How long does a roof replacement take in San Marcos?

Most residential roof replacements take 2–5 days, depending on size and materials.

What is the best type of roof for homes in San Marcos?

Tile and asphalt shingle roofs are popular for their durability, fire resistance, and aesthetic appeal.

Do you handle roofing permits in San Marcos?

Yes, our San Marcos roofing contractors handle all required permits and inspections for your project.

How does San Marcos's inland climate affect my roof?

San Marcos sits in an inland valley that experiences more extreme temperature swings than coastal cities — hot summers, occasional cold snaps in winter, and the periodic Santa Ana wind events that push through the East County corridor. This thermal cycling causes roofing materials to expand and contract repeatedly, which over time can crack tile, loosen shingles, and compromise flashing seals. Santa Ana winds can lift shingles and dislodge tile, making post-wind-event inspections important. Unlike coastal Carlsbad, you won’t deal with salt air corrosion in San Marcos, but UV degradation from the intense inland sun is a significant factor — especially for shingle roofs, which lose granules faster in high-UV environments.
