Call (562) 414-1770Los Altos sits on the east side of Long Beach, a few miles back from the ocean, and it was built out as a post-war tract with single-story ranch homes on regular lots. That makes roofing here fairly predictable in one way: the roof shapes are simple, mostly low to medium pitch with long runs of hip or gable. It is less predictable in another way, because decades of re-roofs, additions and patio covers mean every house now has its own history.
We see a lot of composition shingle roofs near the end of their life, flat-roofed family rooms added in the 1960s and 1970s, and patio covers tied into the main roof with flashing that was never quite right. Our crews repair what can be repaired and tell you plainly when a re-roof makes more sense.
Ranch homes and roofs in Los Altos
Many Los Altos homes were built with lightweight roofing of the era. Over the years most have been stripped and re-covered in asphalt shingle, and some were converted to concrete tile. When a house has had a heavy tile roof put on framing built for something lighter, we look at the rafters and decking before recommending any more weight.
The low pitch is worth understanding. Shingles need enough slope to shed water, and on porches or additions where the slope drops too low, shingles leak no matter how new they are. Those sections usually need a low-slope membrane such as torch-down or TPO, tied cleanly into the shingle field around them.

Roof problems we see most in Los Altos
Low-slope additions leaking
Family rooms and enclosed patios often have a flatter roof than the main house. Ponding water and weak transitions there cause a large share of the leaks we fix in Los Altos.
Brittle aging shingles
Years of inland sun dry out asphalt shingles until granules wash into the gutters and tabs crack. Once that is widespread, patching only buys a season.
Layered roofs
Some homes carry two layers of shingle. Extra layers add weight, hide rotted decking, and generally need to come off at re-roof time.
Patio cover tie-ins
Where a patio cover meets the main roof, missing or rusted flashing lets water run back into the wall. We rebuild those joints with proper flashing.
Working on homes in Los Altos
Los Altos is an easy neighborhood to work in: wide streets, driveways for our trucks, and single-story roofs that make tear-offs quick and clean. A typical re-roof needs a City of Long Beach building permit, which we pull, and inspections, which we schedule. Depending on slope and climate zone, Title 24 can require cool-rated shingles on a re-roof, so we confirm that before ordering.
Being inland, Los Altos gets hotter summer afternoons than the beach neighborhoods, which is hard on shingles and attic spaces. Many of these homes have too little attic ventilation, so we often pair a re-roof with added intake and ridge vents. Our downtown office is a short drive away, and our crews take storm calls here around the clock.

Questions from Los Altos
How long do shingle roofs last on Los Altos ranch homes?
It depends on the shingle, the attic ventilation and how much direct sun the roof gets. Inland heat and UV in Los Altos age shingles steadily, so we judge by condition. Granule loss, cracking and curling tell us more than the age alone.
Can you fix the flat roof on my Los Altos family room addition without redoing the whole house?
Usually, yes. We can replace the low-slope section with torch-down or TPO and rebuild the transition where it meets the shingle roof. If the main roof is also near the end of its life, we will tell you so you can decide whether to do both at once.
Is concrete tile a good choice for a Los Altos home?
It can be, but tile is much heavier than shingle, and many Los Altos homes were framed for a lighter roof. We check the rafters and decking first and will tell you if the framing needs work or if a different material makes more sense.
