AfterTrusted Roofing for Los Angeles Homeowners
Our Roofing in Los Angeles typically runs $9,440-$23,600 for a standard asphalt shingle roof on a single-family home, while repairs start around $470 and most are quoted same-day. Since 2007, Rowan Construction Group has delivered more than 4,000 projects across seven trades, every one with a written price before work started and a documented photo record when the crew left. We’re led by Grant Rowan and operate under The Haven Standard, which means Clause 1 applies from the first phone call: the price is written before anyone picks up a tool. Call (213) 652-7670 to schedule your free estimate - a live person answers 24/7, and your written quote arrives with a flat price, a written scope, and a written warranty.
What Our Roofing Service Includes
Roof Repair
Roof repair addresses isolated damage without replacing the entire system - punctured underlayment, lifted flashing, cracked vent boots, or wind-torn shingles in the wake of Santa Ana gusts. In Los Angeles, we regularly see accelerated deterioration where the marine layer meets inland heat, particularly in neighborhoods like Venice and Santa Monica where salt air corrodes metal fasteners faster than the Basin average. Our crew photographs the damage before touching anything, identifies whether the substrate is dry or saturated, and delivers a written repair scope with a flat price before any work proceeds.
Roof Replacement & Installation
Full replacement becomes necessary when the shingle layer count exceeds two, the decking shows spongy deflection underfoot, or the roof has reached 80% of its rated service life - typically 20-25 years for standard asphalt shingles in Los Angeles UV exposure. We strip to the sheathing, inspect for compromised plywood, install synthetic underlayment where the old felt has degraded, and reflash every penetration. Under Clause 1 of the Haven Standard, your written quote specifies the brand, the series, the warranty tier, and the total cost; no change proceeds without a signed change order.
Metal Roofing
Metal roofing in Los Angeles spans standing seam systems, corrugated panels, and metal shingles miming clay or slate - materials that reflect radiant heat and can reduce cooling loads by 10-25% compared to dark asphalt. We install metal from GAF and Owens Corning, among our fifty-plus vetted brands, and we calculate thermal expansion gaps precisely because Los Angeles diurnal temperature swings stress improperly detailed seams. Our written quote includes the gauge, the finish warranty, and the fastening method - exposed fastener or concealed clip - so you know what you’re buying before you sign.
Tile Roofing
Tile roofing - clay, concrete, or composite - dominates the Spanish Colonial and Mediterranean Revival stock in Beverly Hills, Brentwood, and Pasadena-adjacent neighborhoods. We repair cracked barrel tiles, replace degraded mortar bedding at the ridge, and address the underlying membrane where leaks originate (the tile itself rarely fails; the waterproofing beneath it does). In Westchester and Inglewood, we’ve found original 1950s tile roofs with intact clay but failed 30-pound felt; our Roofing in Inglewood photo documentation shows you exactly what the substrate looks like before we recommend repair versus full replacement.
Specialty Roofing
Specialty roofing covers flat systems, low-slope membranes, green roofs, and custom architectural profiles on modern builds from Abodu, Cover, Dvele, and Mighty Buildings - prefabricated and modular homes we’re increasingly called to service across Roofing in Culver City and Los Angeles County. TPO and modified bitumen membranes require different installation protocols than pitched roofing; we specify seam welding versus torch-applied, the mil thickness, and the manufacturer’s approval status for your particular deck type. For ADU and garage conversion roofs, we coordinate with the structural drawings to ensure the loading matches the membrane warranty requirements.
Gutters & Accessories
Gutters and accessories complete the roof system by controlling runoff and protecting fascia, soffit, and foundation - critical in Los Angeles where concentrated winter rain on impermeable clay soils causes hydrostatic pressure against basement and crawlspace walls. We install seamless aluminum, copper, and galvanized systems with hidden hangers spaced per manufacturer spec, and we calculate downspout capacity based on roof square footage and local rainfall intensity data. Every gutter quote includes the pitch verification, the outlet sizing, and the splash block or underground drainage connection detail.

Brands We Service for Roofing
We’ve installed and repaired GAF roofing systems across Los Angeles since 2009, from Timberline HDZ architectural shingles to their TPO commercial membrane line. We know the difference between their System Plus and Golden Pledge warranty tiers, and we stock common GAF accessories - Cobra ridge vent, WeatherWatch leak barrier, Deck-Armor underlayment - so we’re not ordering materials after we quote you. Owens Corning is equally familiar territory: Duration, Oakridge, and Berkshire lines on pitched roofs, with their Color Contrast palette specified in writing before shingle delivery so there’s no substitution surprise on the truck.
We’ve also serviced and installed metal and tile systems from lesser-known but high-performance manufacturers, and we maintain relationships with regional distributors for Spanish and mission-style clay tile matching on historic properties. Whether you have GAF, Owens Corning, or any other make - including the proprietary roofing assemblies specified by Abodu, Cover, Dvele, or Mighty Buildings on their modular units - we can evaluate it, document it, and quote it in writing with honest numbers rather than inflated ones.

- Water stains on ceilings or walls. Brown discoloration that expands after rain indicates a breach in the roofing membrane or flashing, and in Los Angeles the dry intervals between storms often mask how extensive the saturation has become. We use moisture meters to trace the migration path and determine whether the damage is localized or systemic.
- Granules accumulating in gutters or at downspout outlets. Asphalt shingles shed granules as they age, and heavy accumulation means the UV-protective surface layer is spent; in Los Angeles sun exposure, this accelerates once it starts. We measure remaining granule adhesion during inspection and tell you in plain terms how many seasons remain.
- Visible sagging or waviness in the roof plane. This signals compromised sheathing, often from long-term leakage or inadequate original framing for the tile or composite load - common in 1940s-1960s Los Angeles construction where rafters were sized for lighter materials. We photograph the deflection, measure the span, and specify sistering or replacement in the written scope.
- Cracked, curled, or missing shingles or tiles. Wind uplift from Santa Ana events tears shingles at the sealant strip; thermal cycling cracks clay tiles that lack proper underlayment movement joints. We identify the failure mode because it determines whether spot repair suffices or the system approach has failed.
- Daylight visible through the roof deck in the attic. Any pinhole of light corresponds to a water entry point during rain, and in Los Angeles the infrequent heavy storms can deliver surprising volume through small openings. We map every penetration during our inspection and include the count in your written quote.
Our Roofing Process - Step by Step
- 1
Schedule your free estimate. Call (213) 652-7670 - a live person answers 24/7 - or request through our site. We ask about the property age, the visible symptoms, and any prior repair history so our estimator arrives prepared with the right ladder, moisture detection tools, and material samples.
- 2
On-site inspection and documentation. Our estimator walks the roof where safety permits, photographs all elevations, the attic sheathing, and any interior damage. We note the shingle layer count, the condition of flashing at chimneys and vents, and the state of the ventilation system - ridge vent, soffit intake, or gable vents. You receive this photo record as standard, not as an upgrade.
- 3
Written quote delivery. Within 24 hours, you receive a flat price with line-item breakdown: materials by brand and series, labor hours, permit costs if applicable, and disposal. Under Clause 1 of the Haven Standard, this price is fixed; no work proceeds on any change until the change order is signed, which is the discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs.
- 4
Permit application and material procurement. We pull permits through the Los Angeles Department of Building and Safety, coordinate inspections, and stage materials for your specific color and profile selection - no substitution without written approval. For homeowners in historic districts or HOA-governed communities, we include the compliance documentation in our submittal.
- 5
Installation, final inspection, and documentation. Our background-checked, uniformed crew executes the scope, and a supervisor verifies every detail against the written agreement. You receive the final photo record, the manufacturer’s warranty registration, and our 365-Day Done Right Promise: if it is not done right, Rowan makes it right - backed by The Haven Standard, not a handshake.
How Much Does Roofing Cost in Los Angeles?
A typical roof repair in Los Angeles runs $470-$2,125 depending on the accessibility, the extent of decking replacement required, and whether matching shingles are still manufactured. Roof replacement on a standard 1,500-square-foot home with asphalt shingles falls in our $9,440-$23,600 range, with the lower end representing a single-layer tear-off in straightforward geometry and the upper end accounting for multiple layers, steep pitch, or extensive plywood replacement. Metal roof installation ranges $17,700-$47,200, reflecting material cost differences between corrugated steel and standing seam aluminum, plus the specialized labor for concealed fastening systems. Tile roof repair specifically runs $710-$2,950, while full tile replacement typically exceeds the asphalt range due to weight-handling requirements and the underlayment system upgrade.
Several factors move the price within these brackets. Roof pitch above 6:12 increases labor time and safety equipment requirements. Multiple shingle layers add tear-off disposal cost and may reveal decking damage only visible once stripped. Access constraints - tight Los Angeles lots in Venice or hillside properties in Studio City - affect material staging and crew efficiency. Permit complexity varies: a simple overlay in an unincorporated area processes faster than a full replacement in a historic preservation zone.
To avoid overpaying, get the scope in writing and compare line items, not just totals. A quote that omits underlayment specification, ventilation assessment, or disposal may carry hidden costs later. Our free estimate includes every element; we also offer a Free Second Opinion on any written estimate from another contractor - bring their quote and we’ll review it line by line at no charge. What’s included: the inspection, the photo record, the written flat price, the permit coordination, the installation, the cleanup, and the warranty documentation.

Frequently Asked Questions - Roofing in Los Angeles
Roofing is the installation, repair, and maintenance of the weatherproofing system that protects a building’s structure and interior from precipitation, wind, and solar radiation. For Los Angeles homeowners, this includes the visible covering - shingles, tile, metal, or membrane - plus the hidden components: underlayment, decking, flashing, ventilation, and drainage. Rowan Construction Group evaluates and documents all layers, not just the surface, because failures originate at any level.
A standard asphalt shingle replacement on a 1,500-square-foot home typically takes 1-3 days, while tile or metal installations run 3-7 days due to material handling and fastening complexity. Permitting through Los Angeles DBS adds 2-10 business days depending on project scope and current queue. We include the realistic schedule in your written quote, not an optimistic one - call (213) 652-7670 for a timeline specific to your property.
