Fast, Reliable Roofing Company Across Santa Ana
Finding a roofing company in Santa Ana that actually understands the homes here is harder than it should be. Many of Santa Ana’s neighborhoods are built on pre-1960 housing stock – Craftsman bungalows, Spanish Colonial Revivals, and Mission-style homes that need a different kind of roofing expertise than the tract developments you’ll find in Irvine or Lake Forest. Mercer Roofing has the training, the equipment, and the local knowledge to handle everything from a leaking flat roof on a Bristol Street apartment complex to a full historic tile restoration in Floral Park. We’re a Roofing Company that sends a background-checked, photo-badged technician to your door, with a written price in hand before any work begins. Call us at (743) 200-8347 and a live person answers – 24 hours a day, 7 days a week.
Why Mercer Roofing Is Santa Ana’s Preferred Roofing Company
Santa Ana homeowners call us because we do something most roofers skip: we tell you exactly who is coming to your door before they arrive. Every technician’s name and photo is sent ahead of the visit. They show up in a clean, marked uniform with a photo ID badge. That’s the Threshold Verified standard, and it matters in a city where many residents are home alone during the day, parents with young kids, or older homeowners who want proof of who’s standing on the porch.
Beyond that, our reputation in Santa Ana holds up. Homeowners along North Broadway, Washington Square, and Mabury Park have seen our crews work, and they know what a Mercer job looks like: a written price before work starts, a written guarantee on every repair, and a 365-Day Done Right Promise that says if the work isn’t right within a year, we make it right. Grant Whitlock leads our team with a simple rule: no surprises on the invoice, ever.
Roof Inspection in Santa Ana
Roof Inspection in Santa Ana is the smartest first move for any homeowner in this city, especially if your home was built before 1960. Our inspection goes beyond a quick visual once-over. We walk the entire roof surface, check flashing at every penetration, examine ridge lines and valley conditions, and look for the signs of slow underlayment failure that Santa Ana’s dry climate tends to hide. A typical roof inspection in Santa Ana runs $250 – $450 depending on roof complexity and access, and we document everything with photos so you can see exactly what we see.
What the inspection covers
We inspect the roof covering itself – shingle, tile, metal, or built-up roofing – then go underneath where accessible. That means checking the decking from the attic side when possible, assessing underlayment condition, and flagging any rotted skip sheathing or delaminating plywood. In older Santa Ana homes, that underlayment check is often the moment a homeowner learns their roof is years past its functional life, even if the tiles on top look fine.
What you get afterwards
Every Roof Inspection in Santa Ana ends with a written report and a clear recommendation. If repairs are needed, you get a written price for the work. If a full replacement makes more sense than patching, we’ll tell you that plainly, with numbers. No pressure, no “while we’re up there” upsells. Just facts and a price.
Commercial Roofing in Santa Ana
Commercial Roofing in Santa Ana has its own set of challenges, particularly along the apartment corridors of Bristol Street, First Street, and the industrial pockets near Edinger Avenue. Low-slope and flat built-up roofing systems from the 1960s and 1970s are common on Santa Ana’s multi-family rentals, and many of them are now past their service life. A commercial roof inspection in Santa Ana typically runs $450 – $900 for larger complexes with multiple roof sections, while repairs on BUR systems usually fall between $800 and $3,500 depending on the number of layers and whether the roof has been re-coated before.
Built-up and flat roof repair
We work on the asphalt and gravel built-up roofs that cover so many Santa Ana apartment buildings. The usual failure points are seams, drains, and flashings around HVAC curbs. We patch, re-flash, and re-coat as needed, and we write up exactly what we’ll do before touching anything.
When replacement beats repair
Some Santa Ana commercial roofs have been patched so many times that another repair is throwing good money after bad. If the decking under the BUR layers has been saturated by slow, undetected leaks, a full tear-off and new membrane is the only honest answer. We’ll show you the condition in photos and price both options in writing.
Trusted Brands We Service in Santa Ana
Mercer Roofing installs and repairs roofs using manufacturer-recognized shingle brands including GAF, Tamko, and Boral, along with CertainTeed, Owens Corning, IKO, and Atlas. For Santa Ana’s historic tile roofs, we commonly work with Boral clay and concrete tile, which matches the profile and look of original 1920s and 1930s Mission-style coverings. We stock common fasteners, underlayments, and flashing materials for Santa Ana jobs locally, which means less waiting when your repair is urgent and you want us on the roof now.
Common Roofing Company Problems We See in Santa Ana Homes
- Mortar-set clay tile over skip sheathing. Homes in Floral Park and the Willard district often have original tile set in a full mortar bed directly over wood lath, with no underlayment membrane at all. Pull up a broken tile and you often find the deck beneath is unusable, which turns a small repair into a deck rebuild.
- Santa Ana wind damage at ridges and flashings. Fall and winter gusts routinely exceed 60 mph through Santa Ana’s inland corridors. Loose field tiles, unsealed flashings, and improperly fastened ridge tiles fail every season from November through February.
- Flat BUR roof failure on apartment corridors. Along Bristol and First Street, the 1960s – 1970s built-up roofs are well past their service life. Slow leaks go unnoticed for years in Santa Ana’s low-rainfall climate until the decking rots through and the repair becomes a replacement.
- Hidden underlayment degradation. Because Santa Ana gets almost no rain annually, homeowners don’t see leaks until the sheathing underneath is already compromised. By the time water stains show on the ceiling, the underlayment has often been failing for a decade.

FAQs About Roofing Company in Santa Ana
Because the original tile on those 1920s – 1940s Spanish Colonial Revivals was often set in a full mortar bed directly over wood lath skip sheathing, with no waterproofing membrane underneath. Once you pull up a broken tile and see that, the deck is unusable and the code-correct fix is a full tear-off and plywood rebuild. Crews that don’t know this going in under-bid the job. Call (743) 200-8347 for an honest assessment before you budget.
We write every change into a written change order that you approve before we spend a dollar on it. When a Santa Ana tile swap turns into a deck rebuild, you’ll see the photos, know the new price, and sign off before we order materials. No surprise invoices, ever. That’s part of the written-price commitment on every Mercer job in Santa Ana.
Yes, and it’s something we plan for from the start. When you open up a pre-1960 roof in Santa Ana, current building code often requires solid plywood decking, modern underlayment, and improved fastening methods – all of which add cost to what a homeowner assumed would be a simple tile swap. We write allowances into the contract and price the code requirements in writing before we pull the permit.
Santa Ana sits in a natural wind corridor where fall and winter gusts routinely exceed 60 mph. The acute failures we see every November through February are loose field tiles, improvised ridge fastening, and unsealed flashings that peel open under sustained pressure. If your roof was last serviced by someone who used standard fastening on tile ridges, expect blow-off. We fasten to current wind-load standards for this specific area. Call (743) 200-8347 for an inspection before the next wind event.
Yes. Mercer Roofing does steep-slope historic tile work and low-slope built-up roofing on multi-family properties. That dual capability matters in Santa Ana because the city’s housing stock is so mixed: Spanish Colonial Revivals and Craftsman bungalows sit alongside 1960s – 1970s apartment buildings with flat BUR roofs along Bristol and First Street. Same crew quality, same written-price rule, both roof types.
If your Santa Ana roof needs an inspection, a repair, or a full replacement, call (743) 200-8347 today for a free estimate. A live person answers, a photo-badged technician arrives, and every price is in writing before the work begins. That’s how Mercer Roofing does business in Santa Ana.
