Our crews work in San Marino weekly, we know the code requirements along Huntington Drive and the specific challenges of the estates near Lacy Park, and we give you a written, line-item quote before any work starts. Call (866) 705-2978 to schedule a roof inspection.
Why Marquis Roof Repair Is San Marino’s Preferred Roof Repair Company
Ron Thibodeau founded Marquis Roof Repair on a simple principle: investigate before you recommend. In San Marino, that principle matters more than in any neighboring city. We have opened up original tile roofs on 1920s Spanish Colonial Revival homes off Lombardy Road and St. Albans Road and found what nobody else looked for: failed underlayment, cupped decking, and nail-sick battens hidden beneath tile that looked fine from the ground. San Marino homeowners call us because we document what we find, show you photos, and explain the repair in plain language before any authorization is signed.
Our reputation in San Marino comes from jobs where the tile was saved, the roof actually stopped leaking, and the city’s design review passed the first time. We carry seven manufacturer lines – IKO, Atlas, Tamko, and others – so we are never forcing you into one brand’s color palette. Our teams respond to San Marino service calls within one to two business days for non-emergency work, and faster for active leaks.
What builds trust here is simple: we do not surface-patch a historic roof and call it done. When we find the felt gone and the battens rusted beneath your original clay tile, we tell you. Then we rebuild the roof correctly and document the material match for San Marino’s architectural review. That is the Roof Repair standard we bring to every San Marino estate.
Styles & brands we work with






Flat Roof Repair in San Marino
Flat Roof Repair in San Marino is most common on mid-century additions, garage roofs, and service wings attached to the city’s older estate homes. The hot, dry summers in the 91108 and 91118 zip codes bake roofing membranes until they crack at seams and flashing points, and the first winter atmospheric-river storm lets water find every one of those cracks. Typical flat roof repairs in San Marino run $650 to $3,000, with full membrane replacement on larger low-slope sections landing between $4,500 and $9,500.
Membrane Work on Historic Additions
Many San Marino properties have flat-roofed sunrooms or porte-cocheres added in the 1950s and 1960s. Those membranes have been heat-cycled for sixty-plus years. We replace cracked seams, re-flash the junction where the flat roof meets the main house wall, and match the existing material so the city’s design review does not flag it.
Drainage and Ponding Corrections
Flat roofs on San Marino homes often lack proper slope because the original builder treated them as an afterthought. When water ponds for more than 48 hours after rain, it accelerates membrane failure. We re-grade low spots with tapered insulation and add or reposition drains to move water off the roof before membrane replacement.
Shingle Roof Repair in San Marino
Shingle Roof Repair in San Marino is called for on the city’s larger inventory of 1940s and post-war homes, many of which were built with architectural asphalt or composition shingles rather than the clay tile of their older neighbors. San Marino’s long UV season dries out shingle granules, leaving bare mat exposed. When winter winds strip lifted shingles on homes near the Huntington Library or south of Lorain Road, the repair is straightforward but time-sensitive: a standard shingle replacement on a San Marino home runs $350 to $1,200, while valley or flashing repairs alongside shingle work add $250 to $800 per area.
Storm-Damaged Shingle Replacement
The wind-driven rain during atmospheric-river events hits San Marino from the mountain side. Lifted shingle runs on north-facing slopes are the most common call we get in January and February. We replace damaged shingles, re-seal the laps, and inspect the valley flashing below the repair because that is where the water goes next.
Granule Loss and Aging Shingles
If your San Marino shingle roof is shedding granules into the gutters, the shingles are entering their final years. We inspect for cracks, curling, and exposed mat along the ridges and hips. Repair can extend the life of the roof by three to five years, and we will tell you honestly when replacement is the better financial decision for your home’s value.
Trusted Brands We Service in San Marino
San Marino homeowners do not want a roofer who pushes one brand because that is all they carry. We install and repair products from seven major manufacturers, including Atlas, Tamko, Boral, and IKO. For a tile repair on a 1920s estate, that means we can pull original Boral clay tile and match it with a current profile from the same manufacturer. For a shingle repair, we can match the existing Atlas or Tamko color instead of settling for “close enough.” We keep commonly needed parts and matching flashings available for San Marino work, which keeps turnaround fast and the city’s review process smooth. The right material for your roof is the one that matches what is already there, and that is exactly what we deliver.

AfterCommon Roof Repair Problems We See in San Marino Homes
- Failed felt underlayment beneath reusable clay tile. In San Marino’s 1910s-1940s estates, the tile on the roof is frequently still sound while the felt and battens underneath are disintegrated. The repair is a deck-level rebuild, not a surface patch, and skipping the underlayment means the leak returns at the next major storm.
- Rusted and nail-sick battens causing tile slippage. Eighty years of thermal expansion and contraction works the fasteners loose. Tiles begin to slide, exposing seams. If the battens are not replaced, reset tile will not hold through another San Marino summer heat cycle.
- Flashing failures at chimneys and multi-ridge intersections. San Marino’s estate rooflines are complicated: dormers, valleys, and multiple ridges. Every penetration is a potential leak point, and old galvanized flashing corrodes from the inside. We replace flashing with modern, code-compliant materials and detail the transition properly.
- Water intrusion through valley seams during atmospheric-river storms. The Bobcat Fire burn scar above San Marino raises debris-flow and wind-driven rain concerns during heavy winter events. Valleys that have never been re-lined take the most punishment, and we routinely find saturated decking in these areas when we open them up.
Pricing for Roof Repair in San Marino, CA
Roof repair in San Marino is priced by the square – a roofing square is 100 square feet – plus the cost of materials and any required city documentation. For tile deck-and-underlayment rebuilds on San Marino estates, expect $1,800 to $6,500 depending on the size of the affected area.

FAQs About Roof Repair in San Marino
The original clay tile on a 1910s-1940s San Marino estate is often still sound, while the felt underlayment and wooden battens beneath it have disintegrated after eight decades of thermal cycling. Repairing the visible tile without rebuilding the deck and underlayment would be like repainting a wall with rotten framing behind it. The water will return. A proper repair lifts the salvageable tile, replaces failed decking, lays new underlayment and ice and water shield through the valleys, and resets the tile to match profile and color. Call (866) 705-2978 for an inspection before the next rainy season.
If your home is a visible historic or architecturally significant structure, yes, visible roofing materials can trigger design and cultural-heritage review. Repairs that match the existing tile profile, color, and field pattern generally pass without issue. The projects that stall are the ones where a contractor pulled tile and reset it with a mismatched profile. We document the material match for the city before final, so the review goes smoothly.
We write an allowance into your contract before work starts. If we open the roof and find rotted decking, failed underlayment, or code-triggered upgrades like drip edge and valley flashing, the cost to repair them comes out of that allowance, and you approve it in writing before we touch it. No change orders you did not see coming. This is standard practice on San Marino estate roofs because in our experience, openings always reveal what the surface hid.
A roofing square is a 10-foot by 10-foot area, or 100 square feet. When our San Marino quotes reference squares, they are referring to the surface area of the roof being repaired or replaced, not the home’s floor area. A typical small leak repair might involve half a square, while a large deck-level rebuild on an estate roof could involve five to fifteen squares. The price per square includes materials, labor, and proper disposal of the old material.
Yes. Because we carry seven manufacturer lines including Boral and IKO, we can source a current tile that matches the profile and color of the original 1920s tile you already have. We also set aside salvageable original tiles during a repair and reset them alongside the new material, so the repaired area blends with the untouched field. We photograph every piece before and after, so the city’s review team sees exactly what we matched and how. Call (866) 705-2978 to schedule your roof inspection and get the exact quote.
