Call (562) 414-1770South Gate lies north of Long Beach in the Gateway Cities, between Lynwood, Downey and Huntington Park. The 710 follows the Los Angeles River through the city and the 105 runs along its south side, so our crews reach it with a straight run up the 710. Firestone Boulevard and Long Beach Boulevard are the main streets through town.
Many South Gate homes have been in the same family for decades, and owners here want repairs that last instead of patches that need redoing every winter. We look at the whole roof, fix what is failing, and tell you honestly when a replacement makes more sense than another repair.
Pre-war and post-war houses with roofs on every building
South Gate grew up early, so many neighborhoods have small houses from the 1920s through the 1950s: bungalows, stucco cottages and modest post-war homes on long, narrow lots. A lot of properties have a detached garage, a converted garage or a second house in back, so one address can mean two or three separate roofs.
Asphalt shingle is the main roof on pitched homes, and older houses sometimes still have plank decking under several layers. Rear units, porches and additions tend to have flat or very low-slope roofs with a cap sheet, torch-down or coating. This is an inland city, so summer heat and sun dry out shingles faster than they would near the coast.

Roof problems we see most in South Gate
Several roofs, one address
A main house, a garage and a back unit often have roofs of different ages and materials. We sort out which one is leaking before anything gets torn off.
Cracked cap sheet on rear units
Low roofs on back houses bake in the summer sun, and the cap sheet cracks or blisters. Water then pools and seeps through at the seams.
Heat-cracked tabs on south slopes
Long hot summers dry shingles until the tabs crack and shed granules. South and west slopes usually wear out years before the rest.
Old antenna and dish holes
Old dish and antenna mounts leave screw holes that were sealed with caulk. Once that caulk dries, each hole becomes a small leak.
South Gate permits, tight lots and our route up the 710
South Gate has its own building department, and a re-roof needs a permit and final inspection. We handle both, and we confirm whether Title 24 cool roof rules apply to your roof slope and climate zone before we order material, which matters most on flat and low-slope sections.
Narrow lots and driveways shared with a back unit mean we plan where the dumpster goes and when tenants need access. If two roofs on the property need work, we can do them in one project so you deal with one permit and one cleanup. The drive from our Long Beach office is direct, which helps when a storm opens up a leak overnight.

Questions from South Gate
Can you re-roof both the main house and the back unit on my South Gate lot at the same time?
Yes. Doing both in one project usually saves time on setup, disposal and inspection, and the roofs end up with matching edges and flashing. We price each roof separately so you can see where the money goes.
Is it worth repairing my South Gate roof if it already has two layers?
Small repairs can buy time, but a roof with two layers holds heat, hides rotten boards and makes new nails hard to set. Most of the time we recommend a full tear-off down to the deck. New asphalt shingle runs $5.60 to $9.20 per sq ft, and the real number comes after we look at your roof.
Why does water drip from my South Gate ceiling only during heavy storms?
Light rain often runs off without finding a gap, but a long atmospheric-river storm pushes water sideways and keeps it on the roof for hours. That exposes weak flashing, cracked vents and worn valleys. We trace the path from the stain back to the entry point, which is often several feet away.
