Why Mercer Roofing Is Tustin’s Preferred Roofing Company Company
Homeowners in Tustin call us for one reason more than any other: we tell them exactly who is walking up their driveway before it happens. Every Mercer technician is background-checked, identity-verified, and uniformed, and the person who arrives presents a photo ID badge at your door. You get that technician’s name and photo sent to your phone before the visit. That’s the Threshold Verified standard, and it’s not optional. Not on any job, not ever.
We also write everything down. A written price before any work starts, every time. A written guarantee on every repair, included with every job. If a repair fails within 365 days, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every roof we touch in Tustin. Grant Whitlock leads our team, and he built Mercer Roofing around a simple idea: a homeowner should never have to wonder who’s at the door or what the bill will say. We answer our phones with a live person 24/7, too. No voicemail tree, no call-back form. You call, a human picks up.
Roof Inspection in Tustin
A Roof Inspection in Tustin is the single most important step a homeowner can take before spending a dollar on repairs, and here’s why: this city sits directly in the Santa Ana wind corridor, where offshore wind events in fall and winter routinely hit 40 to 60 mph. Those winds lift unsealed tile edges, blow off ridge caps, and drive debris into valleys. Then the long dry stretch that follows hides the damage. Tustin gets only about 13 inches of rain a year, so a roof can leak for months before anyone notices. By the time the first hard storm arrives, the water has already found its way in. A thorough inspection catches what the dry weather is hiding.
A standard roof inspection in Tustin typically costs $195 to $350, and we always recommend it before buying a home, after any wind event over 40 mph, and for any Tustin Ranch home approaching 30 years old. We walk the entire roof surface, check valleys, flashing, ridge caps, and the underlayment beneath tiles where accessible. We document everything with photos and give you a written report, not a verbal summary.
What We Check on Tustin Ranch Tile Roofs
Late-1980s and early-1990s concrete tile roofs in Tustin Ranch look cosmetically sound from the ground. Tiles unbroken, color intact. But the 30-lb felt underlayment beneath them has often dried out and cracked after decades of inland heat cycles. Waterproofing is functionally gone while the homeowner has no visible warning. We lift tiles in representative areas to inspect that underlayment directly. You can’t quote a re-roof accurately without doing that.
What We Check on Old Town Wood-Frame Homes
Old Town Tustin’s pre-WWII bungalows and Victorians need a different kind of inspection. Original rafter sizing, aged board sheathing, and chimneys that have settled over a century all demand structural evaluation before any re-roof. You can’t just tear off and replace on a 100-year-old frame. We assess what’s actually supporting the roof and flag anything that won’t meet current code before you plan the project.
Commercial Roofing in Tustin
Commercial Roofing in Tustin is a different animal from residential work, and it matters who you call. Flat and low-slope roofs on Tustin’s office parks, retail centers, and industrial buildings need regular maintenance, proper drainage, and repair work that understands how commercial roof systems fail. We handle TPO, modified bitumen, and metal commercial roof systems across Tustin, including the newer commercial developments around Tustin Legacy and the older industrial pockets near Red Hill Avenue.
Commercial roof repairs in Tustin typically run $800 to $4,500 depending on the membrane type, the size of the repair, and access conditions. Full commercial roof replacements run $8 to $18 per square foot installed. Every commercial job gets the same treatment as residential: a written price before work starts, a written guarantee on every repair, and background-checked, photo-badged technicians on site. We coordinate directly with property managers to minimize disruption to tenants and foot traffic.
Preventive Maintenance Programs
Santa Ana wind events are hard on flat commercial roofs in Tustin. Debris collects in drains, membrane seams get stressed, and edge metal can lift. A scheduled maintenance program catches small problems before they become tenant complaints. We set up inspection and maintenance schedules tailored to your building, with written reports after every visit.
Emergency Repair Response
When a Tustin commercial roof fails, it doesn’t wait for business hours. We answer our phones with a live person 24/7 and can dispatch a technician to assess storm or wind damage. The written quote comes before work begins, even on emergency calls.
Trusted Brands We Service in Tustin
We install and repair GAF, Owens Corning, and Boral roofing systems for Tustin homeowners, and we know these products the way a mechanic knows engines. We keep common parts and components locally stocked for fast turnaround on Tustin jobs, which means we’re not waiting on a distributor truck from across the county when your ridge cap is missing after a Santa Ana event. If your home has a specific manufacturer system, we match materials and specifications correctly. Boral tile is especially common on Tustin Ranch homes, and we know how those concrete tile systems should be laid, flashed, and ventilated so they last.
Common Roofing Company Problems We See in Tustin Homes
- Hidden underlayment failure in Tustin Ranch. The tile looks fine from the street, but the 30-lb felt underneath has dried out and cracked after 30 years of inland heat. Water gets through with no visible warning on the surface.
- Santa Ana wind damage. Fall and winter wind events over 40 mph lift tile edges, blow off ridge caps, and drive debris into valleys. The leak that shows up after January rains often started with an October wind event.
- Flashing failures on pre-WWII chimneys. Old Town Tustin’s wood-frame bungalows have chimneys that have settled and shifted over a century. The flashing around them is often original, rusted through, or incorrectly done by a previous patch job.
- Decking rot and structural issues. When underlayment fails on Tustin Ranch homes, water reaches the wood decking beneath. By the time we lift the tile, the decking often needs sections replaced. On Old Town homes, original board sheathing can be too weak for modern code requirements.
Pricing for Roofing Company in Tustin, CA
Here’s what you should expect to pay in Tustin. A small roof repair such as a ridge cap replacement or a flashing patch runs $450 to $850. A moderate repair involving valley work, underlayment replacement, or multiple tile resets runs $900 to $1,850. A full roof replacement on a Tustin Ranch concrete tile home typically runs $14,000 to $28,000 depending on square footage, decking condition, and underlayment specification. Old Town Tustin historic homes often run higher per square foot because of structural assessment, custom flashing work, and period-appropriate material selection.

FAQs About Roofing Company in Tustin
Because the tile surface doesn’t tell you anything about the waterproofing layer underneath it. Tustin Ranch homes built in the late 1980s and early 1990s were typically roofed with 30-lb felt underlayment beneath concrete tile. After 25 to 35 years of inland heat cycles, that felt dries out and cracks even when the tile looks perfect. We see this on nearly every original Tustin Ranch roof we inspect. The first sign is often a ceiling stain after a hard rain, but by then water has already been getting through for months. An inspection costs $195 to $350 and tells you exactly where you stand. Call (743) 200-8347 to schedule one.
Yes, and for good reason. Old Town Tustin’s pre-WWII wood-frame homes require structural assessment before any re-roof. Original rafter sizes and aged board sheathing may not support modern tile loads or meet current code once a permit is pulled. Flashing around old chimneys, period-appropriate material matching, and careful removal of decades-old layers all add labor hours. Expect to pay 15 to 30 percent more per square foot than a typical Tustin Ranch replacement. A written quote from us includes all of that before work starts, so the price doesn’t move mid-project. Call (743) 200-8347 to talk through your specific home.
Yes. Old Town Tustin’s Victorian and Craftsman homes from the 1880s through the 1940s deserve roofing that fits their character. That means specific shingle profiles, proper wood decking replacement where needed, and flashing details that respect original rooflines rather than forcing modern systems onto old frames. We source period-appropriate materials and work with the structural reality of century-old framing. We’ve done this work throughout the historic district, and we’ll tell you honestly what’s feasible and what’s not before you spend a dollar.
We build roofs to survive it. That means proper edge and ridge cap sealing, correct tile fastening patterns, and ice and water shield in valleys where wind-driven debris collects. Tustin sits directly in the Santa Ana wind corridor, and wind events routinely exceed 40 to 60 mph. The difference between a roof that survives those winds and one that loses cap tiles is detail work: nailing patterns, sealant choice, and proper underlayment at the hips and ridges. We were called to a 1988 Tustin Ranch home near the Tustin Ranch Golf Club after a January storm sent water through a valley between two roof planes. The tiles looked unbroken from the ground, but when our tech carefully lifted courses of Boral tile, the original 30-lb felt underneath had dried out and cracked across the entire run. We replaced the failed underlayment with ice and water shield in the valleys, re-set the tile with new flashing and drip edge, and the homeowner hasn’t seen a drop since.
Many of them do, but not because the roof failed. Homes built on the decommissioned MCAS Tustin base during the 2000s and 2010s were often constructed with entry-level asphalt shingle systems rated for 20 to 25 years. Those roofs are now hitting the age for their first major repairs or full replacements. That’s the wave we’re seeing across Tustin Legacy right now. The good news is that a 15-to-20-year-old roof usually has salvageable decking. You may only need a re-shingle, not a full tear-off. A roof inspection tells you whether you’re at that point or you have a few years left. Call (743) 200-8347 and we’ll give you a straight answer.
