Call (562) 414-1770Orange County borders Long Beach on the east across the San Gabriel River, and our La Mirada office sits right at the county line. That makes north and west Orange County a natural part of our service area. We cover Seal Beach, Los Alamitos, Cypress, La Palma, Buena Park, Fullerton, Garden Grove, Westminster, Fountain Valley and Huntington Beach.
Most homes in this part of the county were built in the post-war decades, from the 1950s through the 1970s, and many now carry concrete tile or shingle roofs that are reaching the end of their life. Coastal cities add salt air to the picture, while inland cities deal more with heat and sun. We know these cities because we work in them often: the College Park tracts in Seal Beach, the 1970s tile neighborhoods in Fountain Valley and La Palma, the ranch homes of Garden Grove and Westminster, and the historic streets near downtown Fullerton.
Homes and roofs in the parts of Orange County we serve
Coastal cities such as Seal Beach and Huntington Beach have beach cottages, waterfront homes and 1960s and 1970s tracts, with tile, shingle and flat roof decks. Salt air wears out flashing, fasteners and vents faster here. Many homes have balconies and roof decks that need waterproofing.
Inland cities such as Cypress, La Palma, Buena Park, Garden Grove, Westminster and Fountain Valley are mostly planned tract neighborhoods with one- and two-story homes, often re-roofed with concrete tile. Fullerton adds historic homes with clay tile and hillside homes. Many homes across the area have added solar. Commercial strips along the main boulevards add flat roofs with rooftop units, and townhome complexes add balconies, small flat sections and shared roofs managed by associations.

Roof problems we see most in Orange County
Worn felt beneath concrete tile
Concrete tile from past re-roofs often sits on felt that is decades old. Leaks show up in the first heavy storm.
Salt wear on coastal homes
Homes near the ocean and harbors see faster corrosion of metal parts. Leaks often start at rusted flashing and fasteners.
Solar on aging roofs
Panels installed on older roofs can leak at mounts and make later repairs harder. Many owners re-roof before adding solar.
Additions and patio covers
Room additions and patio covers join the main roof at joints that often leak. Good flashing is key.
Working across north and west Orange County
Every Orange County city we serve has its own building department, and many neighborhoods have HOA rules on roof color and material. We handle permits and inspections and can provide product details for HOA approvals. We check Title 24 cool roof rules before ordering material.
Our La Mirada office is close to Buena Park, Fullerton, La Palma and Cypress, while our Long Beach office reaches Seal Beach, Los Alamitos, Westminster, Huntington Beach and Fountain Valley. We answer the phone 24/7 and dispatch from the nearest office during storms. For larger tile relays we schedule in the dry months when we can, and keep tarps on every truck from November through March so a winter storm does not catch an open roof.
