Why Van Nuys Roofing Co Is Costa Mesa’s Preferred Roof Replacement Company
The homeowners who call us from Mesa Verde, Eastside Costa Mesa, and the Westside tend to have the same complaint: a roofer looked at their roof, pushed one brand, and never mentioned that the marine layer off the coast changes what materials actually hold up. We work differently. Our Roof Replacement team is fluent in seven major manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so the recommendation you get is based on your roof’s condition and your budget, not on which supplier gives us the best margin this quarter. Rick Dominguez leads the crew, and he’s the person who walks your roof, not a sales rep reading from a binder.
We inspect first, recommend second. If your roof has five more years in it, we’ll tell you that. If the decking under that flat Westside roof is already soft from ponding, we’ll tell you that too and show you photos. Costa Mesa homeowners call us back because we don’t manufacture urgency.
Styles & brands we work with






Roof Replacement Contractor in Costa Mesa
A roof replacement contractor in Costa Mesa is someone who can tear off the old system, assess the decking underneath, fix any structural soft spots, and install a new roof that meets the specific demands of coastal Orange County. That last part is where a lot of work falls short. A replacement here is not the same job as one in Riverside or Santa Ana. The salt fog, the morning marine layer, and the dry Santa Ana swings all load the roof differently, and the hardware and drainage details matter more than the shingle brand.
Full Tear-Off and Re-Deck
Many Costa Mesa homes built between the 1950s and 1970s have original decking that’s never been exposed. On flat and low-slope roofs especially, hidden rot under a built-up or foam system is common. We include decking inspection in every quote and price replacement boards by the square foot if they’re needed.
New Roof Installation
For a total replacement on a single-family home in Costa Mesa, you’re looking at $9,800 – $18,500 for a standard asphalt shingle roof, depending on square count, pitch, tear-off layers, and whether decking needs replacement. Flat and low-slope systems run higher because drainage correction, tapered insulation, and membrane costs add up. Every quote is line-itemed so you can see exactly where the money goes.
Asphalt Shingle Roof Replacement in Costa Mesa
Asphalt shingle roof replacement in Costa Mesa covers most of the pitched roofs east of the 405 – think Eastside Costa Mesa, Mesa del Mar, and the neighborhoods around Newport Boulevard. A full architectural shingle replacement on a 1,500 – 2,500 square foot home usually runs $10,500 – $16,500, with tear-off of the old layer included. The coastal twist: we specify stainless steel fasteners and aluminum or stainless drip edge because standard galvanized hardware rusts and bleeds down the fascia within a few years of salt exposure.
Architectural Shingles
Most Costa Mesa homeowners choose architectural shingles over three-tab because they handle the sun-soaked exposure better and look right on mid-century and newer tract homes alike. We install Owens Corning Duration, GAF Timberline, and CertainTeed Landmark lines regularly and know the wind-rating and warranty specs for each.
Roof Decking Replacement
If your shingle roof has been leaking at the eaves or valleys, the decking underneath is usually compromised. Costa Mesa’s morning fog keeps those leaks damp longer than inland homes, which accelerates rot. We replace only the boards that fail inspection, not the whole deck by default.
Trusted Brands We Service in Costa Mesa
We stock and install across the major manufacturers, so you’re not locked into whatever one shop happens to carry. That means Boral concrete and clay tile for the heavier Mediterranean profiles you see around Mesa Verde, GAF and CertainTeed architectural shingles for the tract homes, and Owens Corning for budget-conscious re-roofs that still meet coastal wind and fastener requirements. Seven leading brands, one crew that knows them all. Parts and materials come from local supply yards, so replacement work in Costa Mesa doesn’t wait on out-of-state freight.

AfterCommon Roof Replacement Problems We See in Costa Mesa Homes
- Salt-fog corrosion on fasteners and drip edge: Standard galvanized hardware rusts and bleeds orange streaks down fascia boards within three to five years. We replace every nail, flashing screw, and drip edge with stainless or marine-grade material on coastal jobs.
- Ponding on Westside flat roofs: The 92627 apartment stock and older single-family homes often have flat or low-slope roofs with poor original drainage. Winter rain ponds, the marine layer keeps it from drying, and the decking rots from underneath. A proper replacement corrects the slope, not just the surface.
- Santa Ana cracking on foam and modified-bitumen: The hot dry winds that follow the damp season shrink and crack foam coatings and membrane seams. Valleys and penetrations open up, then take on water when winter returns.
- Mid-century decking failure under built-up roofs: Tar-and-gravel systems from the 1960s and 1970s hide decking damage until tear-off reveals it. We price re-decking as a line item so you’re not surprised mid-job.
Pricing for Roof Replacement in Costa Mesa, CA
Here are real numbers, not vague ranges. A standard architectural shingle replacement on a 1,800 square foot single-family home in Costa Mesa runs $11,000 – $15,000 with tear-off included. Flat roof systems with drainage correction and re-decking on a Westside apartment building run $15,000 – $25,000 or more depending on square footage and structural repairs. Coastal-spec hardware adds roughly $900 – $2,400 to a job versus inland-spec galvanized materials, and that’s the single best money a Costa Mesa homeowner can spend up front. Cheap hardware fails inside a decade and costs far more to remediate. Call (866) 321-6172 for a free estimate with line-item pricing so you can compare bids honestly.

FAQs About Roof Replacement in Costa Mesa
Salt-laden fog from the Pacific holds moisture against fasteners, drip edge, and flashing for hours every morning, and standard galvanized hardware rusts and bleeds within a few years. We specify stainless steel nails, screws, and flashing hardware on every Costa Mesa replacement because it’s the only way to keep the roof watertight and the fascia clean for the life of the system. The upcharge is modest compared to re-fastening an entire roof in eight years. Call (866) 321-6172 for an exact line-item quote on your job.
A proper replacement fixes it. Ponding happens because the original roof doesn’t slope enough toward drains or scuppers, and the marine layer keeps the water from evaporating between storms. We fix it by adding tapered insulation to pitch the surface, relocating or adding scuppers, and sometimes re-cutting drainage channels. Hide-it approaches like adding more coating just add weight and delay the same tear-off. Call us for an inspection and we’ll show you exactly what’s causing your ponding.
Yes. The morning fog and May – June gloom season keep roof decks damp for hours each day, which means cheaper asphalt-saturated felt underlayment stays wet and degrades faster than inland. On Costa Mesa jobs we use synthetic underlayment or a high-grade modified product that resists moisture absorption, and on flat and low-slope systems we add a self-adhered membrane in valleys and around penetrations. The material cost is a small fraction of the job and keeps the decking dry. Call (866) 321-6172 and we’ll walk you through the underlayment spec for your specific roof.
Most Costa Mesa single-family homes run between 18 and 32 squares, where one square equals 100 square feet of roof surface. The average 1,800 square foot home has about 24 – 28 squares of roof area. Comparing bids without a square count is useless – one roofer may price 22 squares and another 30 for the same house depending on how they measured the pitch and overhangs. Our free estimates include a measured square count and a per-square price, so you can compare apples to apples. Call (866) 321-6172 to schedule measurement.
Yes, typically $900 – $2,400 more on a full replacement, and it’s worth every dollar. The coastal-spec version includes stainless fasteners, aluminum or stainless drip edge, corrosion-resistant flashing, and higher-grade underlayment. The inland-spec version with galvanized hardware will look fine for a few years and then start bleeding rust and losing fasteners. Within a decade, you’ll pay more in repairs than the upfront difference would have cost. Call (866) 321-6172 for a quote that shows both specs side by side.
