San Lorenzo Village: early post-war planning, now on its third roof

Construction on San Lorenzo Village began in 1944, when the David D. Bohannon Company started building homes for East Bay war-industry workers, with land set aside for schools, churches, parks and shopping. It is often cited as one of the first planned communities in the country. The first phase ran to about 1951 and produced roughly 3,000 houses.

For roofing, that history matters in three ways. Most Village homes are compact one-story houses with simple gable or hip roofs, which keeps reroofs efficient. They have been reroofed at least once or twice, and stripping the current layer often shows original board decking with gaps, old nail holes and soft spots that need new sheathing. And attics built in the 1940s were rarely vented to modern standards.

Time has added its own layer. Over the decades owners have built family rooms, rear bedrooms and patio covers onto these small houses, and the low-slope joint where an addition meets the original gable is one of the leak points we check first. The street trees planted when the Village was new are now tall enough to drop leaves onto most roofs on the block. The west side sits close to the bay shoreline, so afternoon wind dries and lifts worn shingle edges, while winter storms test old chimney flashing on the masonry fireplaces some houses still have.

From Squattersville to Hesperian Boulevard: San Lorenzo's landmarks

San Lorenzo had 29,581 residents at the 2020 Census and has never incorporated. Its first name was blunter: in 1851, settlers squatting along the line between Rancho San Lorenzo and Rancho San Leandro called the place Squattersville before it took the creek's name. A century later, the Village's commercial heart grew up along Hesperian Boulevard.

• The Lorenzo Theater: the Art Deco movie house at 16080 Hesperian Boulevard opened in 1947, closed in 1982 and was bought by Alameda County in 2010; it is listed on the California Register of Historical Resources.
• Getting in: I-880 along the west side and I-238 at the north edge, then Hesperian Boulevard, Lewelling Boulevard or Grant Avenue into the neighborhoods.
• San Lorenzo Creek: the channel that gave the town its later name runs through on its way to the bay.
• Local services: parks come from the Hayward Area Recreation and Park District, and Alameda County, not Hayward or San Leandro, handles the reroof permit.

No San Lorenzo gallery, just plain coverage facts

We have no San Lorenzo project photos and no review from a San Lorenzo address, so we won't pretend otherwise. You can count on this: San Lorenzo is in our service area, our route is I-880 straight up from Campbell, and 64 Google reviews tell you how our photo-backed inspections and itemized estimates go.

Booking, inspection and the Alameda County permit

We offer the next open Eden Area date. The estimator checks the roof surface, the decking at any soft spots, the flashing and the attic, then sends you photos. Your free estimate arrives in writing with decking replacement priced as its own line, so there are no surprises at tear-off. San Lorenzo is unincorporated, so reroof permits come from Alameda County's Building Inspection Department rather than a city office.

Roof work that fits compact 1940s–50s homes

• Full tear-off reroofs with new plywood or OSB over tired board decking.
• Attic venting upgrades, adding eave and ridge vents during the reroof when it costs least.
• Gutter and downspout replacement on short eaves where overflow lands right at the foundation.
• Chimney removal or reflashing on older masonry chimneys that no longer serve a fireplace.
