Call (562) 414-1770Bellflower borders North Long Beach to its south, so it is one of the quickest trips for our crews, about 15 minutes up Bellflower Boulevard or Lakewood Boulevard. The 91 cuts across the city and the 605 runs along the east side. Our La Mirada office is also within easy reach.
We work for homeowners, small landlords with a few units on a lot, and owners adding or fixing a back house. Many roofs in Bellflower were re-roofed piece by piece as money allowed, so one house can have shingle on the front, roll roofing on a porch and a torch-down roof on a garage conversion. Each part ages on its own clock.
Small older homes, back units and mixed roofs
Much of Bellflower was built in the 1940s and 1950s, with some older homes from the 1920s and 1930s on the original lots. The houses are generally modest one-story stucco or wood-sided homes with simple gable or hip roofs, mostly covered in asphalt shingle. Deep lots led to garages, workshops and second units in the back.
Small apartment buildings and multi-unit lots are common too, often with low-slope roofs behind short parapets. Those roofs use hot mop, torch-down or coatings, and the scuppers and drains get clogged with leaves and debris. With so many additions, the joints between roof sections are where we find the majority of leaks.

Roof problems we see most in Bellflower
Patchwork repairs that keep leaking
Roofs repaired in pieces over decades often have mismatched materials and lapped seams. Water follows the old patch lines, so the drip inside is far from the real entry point.
Garage conversion roofs
Converted garages and back units sometimes kept their original low-slope roofs. Those were never meant to cover living space and often leak at the walls.
Clogged scuppers on rentals
Flat roofs on small apartment buildings drain through scuppers that fill with debris. Water then backs up over the membrane edge during a storm.
Sagging older decks
On some pre-war homes, the original roof boards have weakened from past leaks. Soft areas show up as dips you can see from the street.
Getting roof work done in Bellflower
Bellflower has its own building department, and re-roofs require a city permit and inspection. If you are converting a garage or adding a unit, the roof is part of that larger permit, and we can work alongside your general contractor. For straight re-roofs, we pull the permit ourselves and schedule the inspection.
Lots here are often deep and narrow with tight side yards, so we plan ladder spots and debris drops carefully, especially where a back unit is occupied. Bellflower is inland, so heat and sun are harder on roofs than salt air. Winter storms are when most leaks surface, and we can tarp the same night when a roof starts dripping.

Questions from Bellflower
Why does my Bellflower roof leak in a different spot every storm?
On roofs with many past patches, water can enter at one seam and travel along the deck or rafters before dripping. Wind direction also changes which spots take rain. We trace the path from the attic and the roof surface instead of guessing from the ceiling stain.
Can you re-roof a back unit in Bellflower while tenants live there?
Yes. We give tenants notice of work days, keep the roof dried in at the end of each day, and protect the yard and walkways. Most back unit roofs in Bellflower take one to three days.
What roofing works best on a flat Bellflower garage conversion?
For living space under a low-slope roof, we usually suggest a membrane such as torch-down, TPO or a cool-rated cap sheet, installed with proper edge metal and wall flashing. The choice depends on the slope, drainage and whether cool roof rules apply. We explain the options after we see it.
