Fast, Reliable Roof Replacement Across Coronado
Most full Roof Replacement projects in Coronado run between $14,000 and $32,000 depending on roof size, material, and what we find when the old layers come off. That’s the honest range before we look at your specific roof. A typical 1,800-square-foot bungalow with architectural asphalt shingles lands around $18,000 to $24,000. Flat and low-slope membranes, which cover much of the island’s older housing stock, fall in a similar band but shift based on insulation needs and decking condition. Call (619) 393-3877 and we’ll give you a written price before any work starts – not a rough guess, not a “we’ll see when we get up there.”
Why Tilehurst Roofing San Diego Is Coronado’s Preferred Roof Replacement Company
Coronado homeowners call us because we answer the phone at 6 a.m. and 10 p.m. A live person, every time. That matters when you’ve already been burned by a contractor who vanished after the estimate. Greg Holloway runs our operation with one rule: the written price you sign is the price you pay. No door-knock adjustments. That approach has earned us a strong local reputation across Coronado, from the historic homes near Star Park to the condos along Glorietta Bay.
We schedule Coronado jobs with realistic timelines because we know Coronado. Tight alleys, street parking permits, HOA rules, historic district requirements – we plan for them before the crew arrives. Our technicians are background-checked and uniformed, so when someone climbs onto your roof, you know exactly who they are and why they’re there. And if anything isn’t done right, the 365-Day Done Right Promise means we return and correct it at no charge for a full year.
Scheduling and dispatch are coordinated from our San Diego office, but the crews working on your roof live and work here in the South Bay region. They know what a salt-eaten flashing looks like and they know not to schedule a tear-off on a foggy morning when the marine layer makes roofs slick.

Reroofing in Coronado
Reroofing in Coronado means tearing off the old layers – sometimes two or three of them – and starting fresh with new underlayment, new flashing, and a new surface that actually matches your home and the neighborhood’s character. It’s the right move when your roof is past about 20 years old, when leaks have returned after repeated repairs, or when the decking underneath has started to fail. Most reroofs here run $16,000 to $30,000 for the island’s typical single-story stucco and Spanish-style homes.
Tear-Off vs. Overlay
Some contractors will offer to nail new shingles over old ones. We don’t recommend it on Coronado. Overlays trap moisture between layers, hide decking damage, and add weight that older 1940s framing wasn’t designed to carry. A full tear-off lets us inspect every sheet of decking and replace what’s rotted – which on this island, especially under eucalyptus trees, is more common than homeowners expect.
Historic District Considerations
Many Coronado homes sit in designated historic zones where material choices must stay compatible with the original design. That doesn’t mean you’re stuck with failing clay tile. It means we work with lightweight composite tile or architectural shingles that read as period-appropriate while giving you a modern underlayment system underneath. We’ll handle the paperwork and coordinate with the city’s design review process.
Flat Roof Replacement in Coronado
Flat Roof Replacement on Coronado almost always involves a built-up asphalt roof, modified bitumen, or a single-ply membrane like TPO, and most jobs run $15,000 to $28,000 depending on square footage and whether the decking below needs repair. These roofs dominate the island’s 1920s – 1950s Mediterranean stock, and they fail differently than pitched roofs. The membrane itself might look fine while the seams, scuppers, and flashings quietly leak into your ceiling.
Membrane Options That Hold Up to Salt Air
TPO is our most common recommendation for flat roofs within blocks of the ocean. It’s heat-welded at the seams, resists salt corrosion, and reflects Coronado’s moderate UV exposure better than older asphalt systems. For homes on the bay side where ponding from clogged scuppers is the bigger issue, modified bitumen can be a better fit. We walk every roof, measure the slope, check the drains, and then recommend – never just “whatever’s on the truck.”
Decking and Drainage Repairs
Before any membrane goes down, we inspect the decking. On A Avenue near Spreckels Park, our crew replaced a built-up asphalt roof and found the original 1940s decking had rotted along the north slope where eucalyptus shade kept it damp year-round. We removed two layers of old roofing, repaired the decking, installed a new GAF TPO membrane with stainless-steel drip edge and flashing, then added a ridge vent to stop the chronic moss growth. That’s the difference between a roof replacement that lasts 25 years and one that fails in seven.
Trusted Brands We Service in Coronado
We install and service roofing systems from seven major manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so the material fits your home, your historic district requirements, and your budget, not whatever happens to be stacked in a warehouse. That matters on Coronado, where a 1920s flat-roof bungalow needs something different from a newer condo building. We stock common components locally and can source specialty items quickly for Coronado jobs, including marine-grade flashing and stainless-steel fasteners that standard suppliers don’t keep on hand.

AfterCommon Roof Replacement Problems We See in Coronado Homes
- Galvanized flashing that corrodes in under a decade. Ocean-side homes on the west edge of the island lose galvanized flashing after just 5 to 8 years. Standard flashing here means caulk pulls away and leaks appear around vents and pipes. We specify stainless steel or aluminum on every Coronado replacement.
- Flat-roof scuppers clogged with eucalyptus leaves. Pine needles and those leathery eucalyptus leaves pile up fast, block the drains, and create ponding water that eats through membranes. Homes near Spreckels Park and the golf course see this constantly.
- Clay tile underlayment failing while tiles look fine. Many historic tile roofs on the island fail at the underlayment long before the tiles wear out. Homeowners patch broken tiles and never see the water damage happening to the decking underneath.
- North-slope moss growth despite Coronado’s dry reputation. The “banana belt” climate doesn’t stop moss on shaded north slopes under mature trees. Persistent marine layer keeps those surfaces damp, and moss holds moisture against the roofing material, accelerating rot.

FAQs About Roof Replacement in Coronado
Ocean-side homes need marine-grade metals on every flashing, vent, and fastener because salt spray corrodes standard galvanized components up to twice as fast. We also schedule earlier inspections for west-facing homes and recommend stainless-steel drip edge as a baseline on that side of the island. Bay-side homes still deal with salt air from San Diego Bay, but the failure normally shows up as ponding and drain clogs rather than fastener corrosion. Call (619) 393-3877 and we’ll tell you which side of the island your roof is on and what that means for your replacement.
Yes, in most cases you can keep the original profile while replacing the membrane and underlayment underneath, which is what actually protects your home. We coordinate with the city’s design review process and choose materials that appear period-appropriate, whether that’s a modified bitumen with a matching color or a TPO membrane hidden behind the parapet. The goal is a roof that looks like it belongs on your home but performs like a modern system.
The marine layer keeps Coronado’s shaded north slopes damp for months at a time, especially under eucalyptus trees that block direct sun. Moss grows in that persistent moisture and holds water against the roofing surface, which accelerates membrane breakdown and decking rot. The fix involves improving drainage, trimming overhanging branches, and sometimes adding a ridge vent or additional slope to stop water from lingering.
Most Coronado bungalows run between 18 and 28 squares, or 1,800 to 2,800 square feet of roof surface. Smaller cottages near the beach can be 14 to 18 squares. A “square” is 100 square feet, and roofers price by the square plus materials and tear-off. The only way to know your exact count is to have someone measure, which we do free during the estimate.
Rotted decking under a membrane that still looks intact, almost always on the north slope or near clogged scuppers. Water gets under the membrane at a failed seam or penetration, soaks the plywood, and stays there because the flat roof doesn’t shed water fast enough. By the time you see a ceiling stain, the decking is usually already compromised. That’s why we inspect the decking during every estimate and include repair costs in the written price rather than surprising you after the tear-off.
