Call (562) 414-1770Santa Ana is southeast of Long Beach in central Orange County, and it is the county seat. The 5, 22 and 55 all cross the city and the 405 passes near its southern edge, so our crews come down the 405 or across on the 22 depending on the neighborhood. Main Street, Bristol Street and First Street carry much of the local traffic.
Many Santa Ana homes hold large families or more than one household, and the roofs work hard. Owners usually want a fair repair first and a clear plan for replacement later. We give you both, with typical price ranges and photos of what we found.
Craftsman bungalows, Spanish cottages and big post-war tracts
Santa Ana's older neighborhoods near downtown hold Craftsman bungalows, Spanish Revival cottages and other homes from the early 1900s through the 1930s, several of them in recognized historic areas. Around them are large post-war tracts of single-story houses from the 1950s and 1960s, and many streets have apartment buildings, fourplexes and converted garages.
Asphalt shingle covers most bungalows and tract homes, while Spanish-style homes and some newer houses have clay or concrete tile. Apartments, additions and many rear units have flat or low-slope roofs. The city is inland, with hot summers, strong sun and fall Santa Ana winds.

Roof problems we see most in Santa Ana
Low-pitch bungalow porch roofs
Front porches on older bungalows often have low-slope roofs that were shingled anyway. Water backs up under the shingles and rots the porch beams.
Fourplex roofs with many penetrations
Small apartment buildings carry vents, AC stands and plumbing pipes through a flat roof. Each one is a seam that dries out and leaks.
Broken barrel tile on old cottages
Older Spanish cottages often have clay tile held with aging nails or mortar. Tiles slide and crack, exposing felt that is decades old.
Hidden rot under layered roofs
Many houses carry two roofs, and the bottom one hides soft decking. We find it during tear-off and replace boards before new material goes on.
Santa Ana permits, historic blocks and multi-unit properties
Santa Ana has its own building department, and re-roofs need a permit and inspection. Homes in the city's historic areas can need extra review before visible material changes, such as swapping clay tile for shingle, so we confirm that early. We also check whether Title 24 cool roof rules apply before we order material.
On fourplexes and apartment buildings, we schedule around tenants, keep walkways clear and protect cars parked close to the building. Santa Ana is an easy reach from both our Long Beach and La Mirada offices, and our phone is answered around the clock when a storm brings water through a ceiling.

Questions from Santa Ana
Can I change the roof material on a historic Santa Ana bungalow?
Sometimes, but homes in Santa Ana's historic areas can need review before a visible change, so we check with the city first. Many owners keep the original look with shingles in a fitting color or by keeping the clay tile. We give you options that should pass review and explain the cost of each.
What is the best flat roof for a Santa Ana fourplex?
It depends on the slope, the drains and how much rooftop equipment there is. TPO, torch-down and hot mop all work, and a white TPO surface helps with cool roof rules and summer heat. Flat roof replacement runs $6.40 to $13.90 per sq ft, and the real number comes after we look at the roof.
Why does the porch ceiling on my Santa Ana home have water stains?
Porch roofs are usually lower in pitch than the main roof, and on many older homes they were covered with shingles that need more slope to shed water. Rain backs up under them in long storms. We often fix it with a low-slope membrane on the porch and new flashing where it meets the house.
