Roofing RIB Company repairs and replaces roofs across Northridge, from Sherwood Forest and the streets around Cal State Northridge to the blocks along Reseda Boulevard and Nordhoff Street: composition shingle and concrete tile on the ranch homes, and low-slope membranes on the apartment buildings near the university. Permits through LADBS, City of Los Angeles. Leak calls answered 24/7. Free estimate: (818) 600-6707.
1950s–70s ranch homes, larger custom ranches under the old trees of Sherwood Forest, and apartment and condo buildings around Cal State Northridge make up most of Northridge. The roofs that go with those houses are composition shingle and concrete tile on the ranch homes, and low-slope membranes on the apartment buildings near the university.
The January 1994 Northridge earthquake left chimneys and roofs across the neighborhood repaired or rebuilt, and a shingle roof put on during that rebuild is now more than thirty years old, past the service life of most shingle in Valley heat.
Shingle re-roofs on the 1950s–70s ranches, tile underlayment work on the larger ranches, and flat-roof repairs on the apartment buildings near CSUN are the typical roofing jobs in Northridge. Every job from Roofing RIB Company starts with a free inspection: the slopes walked, the flashing and penetrations checked, the attic side where we can reach it, and photos of what we found. A leak gets a written price for the repair at the actual entry point; a roof at the end of its life gets a written replacement quote with a full tear-off to the deck, a per-sheet decking allowance, synthetic underlayment, new flashing and vents, and the covering that fits the house.
Permits go to LADBS (City of Los Angeles) at the Van Nuys Development Services Center, 6262 Van Nuys Blvd. LADBS issues most shingle re-roofs as an express permit (no plan check) when the covering is Class A or B and weighs under 6 lb/sq ft over solid sheathing; tile and other heavier coverings go through the standard permit process. Within the City of Los Angeles, a residential roof replacement covering more than 50% of the roof area must use a cool roof product labeled and certified by the Cool Roof Rating Council.
Leak detection on the roof and in the attic, then the fix at the entry point: flashing at chimneys, walls and skylights, pipe boots, valleys and seams.
Tear-off to the deck, decking allowance in writing, synthetic underlayment, new flashing and vents, then shingle, tile, metal or a low-slope membrane.
Tile lifted, new underlayment installed and the same tile relaid when the tile is sound and the underlayment beneath it is not.
Torch-down and TPO repairs and replacements, silicone coatings over sound membranes, and drainage fixed so water leaves the roof.
Leak calls answered 24/7; tarps and temporary sealing during rain, credited toward the permanent repair.
LADBS express permit for most shingle re-roofs, the standard permit process for heavier tile; final inspection scheduled and the closed permit handed over.

LADWP is the electric utility, the one to coordinate with when a re-roof is paired with solar or an electrical service upgrade.
| Scope | Planning range | What's included |
|---|---|---|
| Leak or flashing repair | $350–$1,200 | Locate the source, replace damaged shingles or membrane, reseal or replace flashing at a chimney, skylight, vent or wall. Tile and flat roofs sit toward the top of the range. |
| Emergency tarp / dry-in | $250–$600 | Temporary cover during rain so the interior stops taking water; credited toward the permanent repair when we do it. |
| Architectural shingle re-roof | $12,000–$25,000 | Full tear-off of a 1,500–2,500 sq ft roof, synthetic underlayment, new flashing and vents, CRRC-rated cool-roof shingle where the City requires it, permit and haul-away. |
| Concrete tile | $10–$18 per sq ft | New concrete tile over new underlayment and battens; plan-check permit because tile exceeds the 6 lb/sq ft express-permit limit. |
| Torch-down (modified bitumen) | $4.50–$8 per sq ft | Two-ply torch-applied membrane over a base sheet, new edge metal and scuppers; the standard on Valley garage conversions and room additions. |
Planning ranges compiled from the published cost guides listed below, not a price list; the repair guides are national figures and Los Angeles labor sits above them. Roof size, pitch, layers, decking and access move a real Northridge quote. Your written quote after a free inspection sets the price.
A roofer, not a salesperson, walks every slope, checks the flashing, penetrations and attic side, and photographs what they find. You get a straight answer on repair versus replacement.
An itemized written quote for the roof: tear-off, decking allowance, underlayment, covering, flashing, vents, permit and haul-away. The price in the quote is the price on the invoice unless you change the scope.
We pull the permit, protect the property, complete the work in the quoted window and schedule the final inspection. You get the closed permit and the material warranty paperwork at the end.
Tell us what is going on with the roof: a leak, its age, the material. A roofer will call to schedule a free inspection at your Northridge home.

The Roofing RIB Company team came out to look at our roof since we had a few leaks. He was really professional and explained the whole roof structure and what caused the leak. We ended up replacing the whole roof because it was almost 35 years old; the price was reasonable compared to the other quotes we got. Would definitely recommend Roofing RIB Company.
I've had many roofers come to check my roof and got a wide variety of quotes, sales gimmicks and outright lies. This company was nothing like that. They called right back when I asked for a quote and made an appointment. When they showed up, they took measurements, explained their process, and gave me a copy of their insurance and bond documents, and a clear and simple contract that made sense. They came on the agreed day and finished the job quickly and efficiently. It looks good.
Can't be happier. They did my roof and solar system combo deal with no-APR financing.

It depends on the house. In Northridge that usually means composition shingle and concrete tile on the ranch homes, and low-slope membranes on the apartment buildings near the university. We quote the option that fits the house and the budget, and tell you when a cheaper one would be the wrong call.
