At Wedge Roofing, we take pride in preserving San Francisco Bay Area history through our award-winning Historic Roof Restoration Service in San Francisco, Marin County, Napa, Sonoma County and the East Bay. We specialize in restoring the architectural integrity of historic buildings from late 19th Century Victorian homes to Mid-Century post-war residences including Eichlers and even 1970’s-era Geodesic Domes.

Our roof restoration work includes buildings designated as historic landmarks by the National Register of Historic Places, California Register of Historic Resources and local San Francisco Bay Area preservation organizations.

Miller Creek Schoolhouse – 1864
National Register of Historical Places #72000236

The Miller Creek Schoolhouse in San Rafael, CA is the oldest one-room schools in Marin County. The single story school is a simple adaptation of the Italianate architectural style popular in the earliest San Francisco Victorians. Our roof restoration team replaced the hip roof.


Brewster Hill Victorian – 1872
Heritage Home

After Wedge Roofing completed the roof on this stunning Queen Ann Victorian, the owner wrote, “I appreciate the fact that the Wedge Roofing crew took the time and extra precaution necessary to protect my 126 year-old Heritage Home.”


Healdsburg Farmhouse – 1880

This saltbox style farmhouse in the Alexander Valley close to Healdsburg was the home of famed artist Richard Diebenkorn. Historic roof preservation of this important home included the installation of a GAF shingle roof and re-installation of the rooftop iron tracery.


San Francisco Victorian – 1882
Home of Henry Geilfuss

Considered the most prolific San Francisco architect of his time, Henry Geilfuss designed over 450 Victorians in the late 19th century, many now designated as historical landmarks. For his own home built in 1882, Geilfuss designed this Italianate-style Victorian Townhouse in San Francisco’s Mission District. The home retains the architect’s signature element of delicate floral embellishments carved into the redwood corner boards and porch posts. Following decades of decline, preservation of this Victorian reached a low point as roof failure allowed interior water infiltration. This critical situation was not only jeopardizing the occupants and their belongings, but also imperiling the integrity of the historic structure itself. The Wedge historical roof restoration team removed multiple layers of built-up roofing, carefully preserving the roof’s exterior decorative elements before installing a new roof system. With a secure, protective roof, the homeowner then could proceed with further renovation of this historic gem.


Mutual Relief Building – 1885
Petaluma, CA

Queen of Petaluma’s historic “Ironfront Row” is the stunning Italiante style “Mutual Relief Building” which was designed by renowned San Francisco Bay Area architect John M. Curtis and features a cast iron facade. Wedge Roofing was honored to be selected to install a new flat roofing system on many of the block of buildings in “Ironfront Row” including the Mutual Relief Building.


Andresen’s Tavern – 1885

Adjacent to the Mutual Relief Building in the “Ironfront row” of historic buildings in downtown Petaluma is Andresen’s Tavern. The cast iron facade Italianate designed building was built in 1885.


McMorry-Lagan Residence – 1889
San Francisco Historic Landmark Victorian #146

An insulated spray foam roof was installed on this designated San Francisco historic landmark Victorian built in 1889 by Farrell McMorry and designed by architect Thomas J. Wales.


Petaluma Silk Mill – 1892
National Register of Historic Places #860000386
California Register of Historic Resources

When our roof restoration specialist inspected this historic textile mill, the original tin-plate standing seam roofs were rusted with areas of corrosion allowing interior water infiltration. Our roof restoration team carefully treated the corroded areas and coated the metal roof, pyramidal towers and cupolas. This work successfully halted the water intrusion and extended the life of this historic roof.


Petaluma Victorian – 1895
Heritage Home

This beautiful 1895 Sonoma County Heritage Home captures the architectural charms of the Queen Anne style. The asymmetrical facade with wrap around porch is highlighted with a corner tower covered in differing patterned wood shingles. Wedge Roofing is proud of our work on this multi-leveled, highly steeped roof with tower and turret.


San Francisco Victorian – 1895


San Francisco Queen Anne Victorian – 1895


Petaluma Victorian – 1901

The elegant two-story Colonial Revival style home’s architectural features include triplet shed dormers. The hip roof has an enclosed soffit with a Dutch Gutter system and a Chatham dentil trim line.

Restoring the original wood shingle roof was not an option, as it lay under many roof recovers. Therefore, the existing roofs were removed to reveal the original rough redwood skipped sheathing boards, which were preserved. Our roof restoration crew installed solid sheathing and a new composition shingle roof.


Sausalito Presbyterian Church – 1909

This stunning Gothic Revival Church Designed by Ernest Coxhead, was built in 1909. The Sausalito congregation lovingly restored the church in 2002. As part of the restoration team, Wedge Roofing completed refurbishment to the fire-damaged manse and installed a new roof and shingles for the garage.

San Anselmo Town Hall Tower – 1911
Award Winning Historic Roof Restoration

Wedge Roofing’s restoration of San Anselmo’s historic tower was awarded as the “Top Real Estate Project of 2014” by the North Bay Business Journal. After 75 years, our historical roof restoration returned the San Anselmo Town Hall Tower to W. Garden Mitchell’s original 1911 design. The five-story Spanish Revival style Bell tower, originally built with a clay tile square roof, was modified in the 1930’s for placement of a radio antenna. Working from original 1911 construction images our historic restoration team methodically reconstructed the tile roof and upper section of the tower including the archway, doors and turned balusters. All work was completed accommodating the nesting owls in Marin County’s historic tower.

Second Empire French Baroque Revival


Hotel Sausalito – 1915

Spray Foam Roofing provided an energy-efficient, watertight roof for Sausalito’s historic hotel built by San Anselmo builder Peter Hamilton in 1915.


Willis Polk Townhouse San Francisco – 1917


Marble Court Apartments – 1923
National Register of Historic Places #91000957

Designed by architect Edward H. Denke in 1923, the stucco cladded six-story Marble Court Apartment is a contributing historic building of the Lower Nob Hill Apartment Hotel District.

A key design element of these downtown San Francisco historic buildings is the consistency of the boldly projecting roof cornices. The Marble Court Apartment features an Italianate entablature roof cornice constructed of galvanized iron. In 2013, amidst adjacent new construction, Wedge Roofing was hired to preserve and restore the structural integrity of the historic apartment’s decorative metal roof cornice.


OakHill Brewster Craftsman Bungalow – 1924
Award Winning Historic Roof Restoration

Wedge Roofing’s historic roof restoration and exterior preservation work on this 1924 Craftsman Bungalow was honored with the 2013 Heritage Homes of Petaluma Preservation Award.


Marin County Mid-Century Modern – 1954
Award Winning Historic Roof Restoration

The spray foam roof installation on this Marin County landmark home won the 2018 First Place Award for Best Spray Foam Roof Nationwide from the Spray Polyurethane Foam Alliance (SPFA).

Both technically challenging and architecturally significant, the award-winning spray foam roof was installed on a 1954 atomic-era home designed by famed mid-century modern architect Mario Corbett in the Marin County Headlands above Sausalito.

To bridge the 1950s-era structure with the consistency and dependability of a contemporary roofing system, Wedge Roofing designed a highly insulating foam roof providing the air-sealing, energy-efficient characteristics not available in the original ceiling and roof assembly construction.
