“Once we decided to replace our aging concrete tile roof on our recently purchased Lake San Marcos house, we faced the stressful but important task of choosing the right roofing material as well as finding a reputable and dependable roofer. We found that roofer in Mark Anthony Construction. Having read reviews of him and his company, my wife and I were very happy to find he and his company did indeed meet our expectations. From our first meeting with Mark, we felt like we were in good hands. We found him friendly, knowledgeable and professional. He provided us with all the information necessary to make an informed decision. Once we decided on the type of roof we wanted, we set a start date. Mark’s company stays busy so our start date was several months in the future, but we were happily surprised when an earlier start day became available. His crew arrive on the agreed upon date and time, in fact he and his crew were always “on-time”. The work went smoothly and each evening the area around the house was cleared of any debris. They provided their own “porta-potty” and the only thing we provided was use of an electrical outlet. The work was completed on time, and looks great. Mark pays all the suppliers and other than the initial deposit we paid nothing until the job was done to our satisfaction.
Mark Anthony is not inexpensive, but he is fairly priced, and delivers an excellent product. My building inspector friend happened by when construction was underway and remarked, “Wow, state of the art materials”! We haven’t had any rain yet, but our new asphalt roof was advertised to keep the attic and therefore the house cooler. Well, it’s a 101 outside today, we kept our doors and dual-paned windows closed, but have not turned on the AC, and inside it is 78 degrees! If you are in need of a new roof, do yourself a favor and contact Mark Anthony before you move forward.”

“We recently had Mark Anthony reroof my parents’ home, which we use as a rental, since everything went so well with our own home (see review below). They removed the old aluminum “simulated shake” roof, replaced a lot of rotted fascia, sheeted it and shingled it all with nice high-definition asphalt shingles. It looks much, much better! And it has a 50- year warranty backed by GAF! The green in me appreciated that they recycled all that aluminum. Everything went very well, no surprises there. Quality work, everything left tidy every day, just as we knew it would be.
Thanks, guys, for another great job!”

“I just had Mark Anthony Construction and Roofing remove and replace my existing roof shingles and repair termite damage.
We met Ted Figart, and later Mark at our (project) home to discuss the needed work and estimated cost of repairs. We were impressed by their knowledgeable, professional demeanor. Their crew arrived every day on time and started work immediately. It was obvious this crew worked well as a team. At the end of the day, they cleaned everything up and prepared for the following day. I do not know their names, but a detail person named Diego did an outstanding job and is a credit to this organization. I would recommend Mark Anthony Construction and Roofing.”

Why We Replace, Not Repair
Asphalt shingle roofs typically fail at the underlayment and flashing layers, not just the surface shingles. Repairs often delay—but do not solve—these issues.
- Water Intrusion: Failed underlayment leads to hidden moisture damage and deck deterioration.
- Warranty & Insurance Compliance: Only full roof replacements qualify for manufacturer warranties and insurance documentation.

Asphalt Shingle Roof Replacement FAQs — San Marcos, CA
How much does asphalt shingle roof replacement cost in San Marcos, CA?
The cost of a full asphalt shingle roof replacement in San Marcos typically varies based on roof size, slope, ventilation requirements, and the specific shingle system selected.
In San Diego County, pricing also reflects full tear-off, updated underlayment, flashing, and code-compliant installation. Because this is a complete roofing system replacement, costs are higher than surface-level work but provide long-term durability and warranty eligibility.
How much does it cost to replace an asphalt shingle roof on a 2,000 sq ft house?
For a 2,000 sq ft home in San Marcos, the cost to replace an asphalt shingle roof depends on roof complexity, pitch, number of penetrations, and ventilation upgrades.
In San Diego County, a full roof replacement includes tear-off, new underlayment, flashing, and architectural shingles installed to manufacturer standards. Final pricing is determined after an on-site evaluation of the complete roofing system.
Can you replace just a few asphalt shingles instead of the whole roof?
No. We specialize exclusively in full asphalt shingle roof replacements for San Marcos and San Diego County homeowners.
Once an asphalt shingle roof reaches the end of its service life, partial work does not restore system integrity, meet manufacturer requirements, or qualify for warranty or insurance documentation.
Will a roof leak if one asphalt shingle is missing?
Yes, a missing asphalt shingle can allow water intrusion beneath the roofing system, especially during wind-driven rain common in San Diego County.
However, isolated surface issues often indicate broader system failure beneath the shingles. In San Marcos, the long-term solution is a full roof replacement that restores underlayment, flashing, and waterproofing as a complete system.
What is the best time of year to replace an asphalt shingle roof in San Diego County?
Asphalt shingle roof replacement can be completed year-round in San Diego County due to the mild climate.
Many San Marcos homeowners choose to replace their roof before the rainy season or during insurance renewal periods. Scheduling a full roof replacement earlier can help avoid weather-related delays and compliance pressure.
Will insurance cover asphalt shingle roof replacement in San Marcos?
Insurance coverage for asphalt shingle roof replacement in San Marcos depends on policy terms, roof age, and documented condition.
In many cases, insurers require a full roof replacement—rather than partial work—to maintain or renew coverage. While coverage is never guaranteed, proper documentation from a complete roof replacement is often required by insurance carriers in San Diego County.
