Roof Replacement in Pasadena — Written Price, Workmanship Warranty

Fast, Reliable Roof Replacement Across Pasadena

Roof replacement in Pasadena runs roughly $9,800 to $24,000 for a typical single-family home, with acreage properties and detached structures often landing higher because of permitting, hauling distance, and decking prep. Most Pasadena replacements take three to seven working days once materials are staged and the underlayment goes down. We serve every corner of the city, from the Craftsman streets of Bungalow Heaven to the county-lined acreage off North Allen Avenue and the open lots east toward Hastings Ranch. If you’re weighing a tear-off versus an overlay or wondering what your oak canopy is doing to your shingles, call us at (866) 974-2271 and we’ll walk the roof with you before you commit to anything.

Key Takeaways:

• A full tear-off and replacement on a Pasadena bungalow or ranch typically costs between $9,800 and $24,000 depending on decking, pitch, and material class.
• Reroofing on unincorporated acreage adds county permitting, hauling logistics, and sometimes septic or well setback work that city-lot jobs never face.
• We work with GAF, Atlas, and Tamko among seven manufacturers, so your shingle choice follows your roof and your budget, not our stockroom.
• Koreatown Roofing does one trade: roofing. Inspection, repair, replacement. Nothing else pulling our focus.

Why Koreatown Roofing Is Pasadena’s Preferred Roof Replacement Company

Pasadena is a city of old rooflines. Low-pitch Craftsman gables, Spanish Colonial clay tile, bungalows with original skip sheathing, and a canopy of deodars and coast live oaks that never stops dropping. That combination rewards a roofing company that reads a roof the way a mechanic reads an engine, and it punishes generalists who show up once and subcontract the hard parts. We’re roofing specialists, not generalists. Every job we take in Pasadena is a roof job, from the first ladder climb to the final inspection.

Manny Cordero leads our Pasadena work personally. He’s the one who checks the valleys on a Bungalow Heaven tear-off before we quote, and the one who walks a half-acre lot off North Allen to see whether the county setback rules will push shingle delivery back a week. That kind of accountability is why so much of our Pasadena work comes from neighbors telling neighbors. When a crew’s reputation lives on the street where it works, the standard changes. We’re fine with that.

Response to Pasadena is measured in days for estimates, and our replacement schedule is set at quote time, not shuffled after you sign. No rotating crews, no call-center dispatch. When you call (866) 974-2271, you’re talking to people who know what an old skip-sheath deck looks like and why a straight tile-to-tile swap on a Spanish Colonial needs a matched profile, not a generic substitute.

Reroofing in Pasadena

Reroofing in Pasadena means a full tear-off of the existing roof and a new system built up from the decking. That’s the only honest way to handle most early-1900s Craftsman bungalows and 1920s Spanish Colonials in this city, where original roofs are often a century old and the underlayment has turned to dust. A Pasadena homeowner typically needs reroofing when granule loss shows in the gutters, when flashing has cracked around a chimney or dormer, when leaks appear at the valleys after winter rain, or when a second layer of shingles has already been laid over the original and the decking underneath is failing. On acreage lots, we see the same but often with more water damage at the fascia line, because drainage wasn’t graded properly decades ago. Reroofing in Pasadena typically runs $11,000 to $24,000 depending on decking replacement, pitch, and the shingle line you choose.

What Gets Torn Off

The old shingles, the felt or synthetic underlayment, the drip edge, and often the first rows of decking at the eaves and valleys. On Pasadena’s older homes, that usually means the original skip sheathing, which sits with gaps between boards. Building code now requires a solid nail surface, so most Pasadena reroofs include re-decking over skip sheath or replacing rotted sections entirely.

What Goes Back On

New decking where required, a water-and-ice shield in the valleys and at the eaves, high-grade synthetic underlayment across the field, new drip edge at every eave and rake, and then the shingles. For Pasadena’s many low-pitch bungalow roofs, we also check the pitch itself before we recommend a shingle line. A 2:12 pitch doesn’t perform like a 6:12 pitch, and we’d rather tell you that before we order materials than after the first winter.

Flat Roof Replacement in Pasadena

Flat roof replacement in Pasadena is common on mid-century ranch homes, detached ADUs, garage roofs, and the long, low outbuildings that sit on acreage properties around the city’s edges. These roofs fail differently than shingle roofs. Water ponds. Seams crack under sun and Santa Ana heat. Debris from the tree canopy plugs drains and scuppers, and then a winter rain finds every weak point at once. A flat roof replacement in Pasadena generally runs $8,500 to $18,000 for a standard residential surface, and more when the decking under a ponded area has rotted or the slope was never built correctly in the first place.

Ponding and Drainage

A flat roof only works if water leaves it. On Pasadena acreage, where outbuildings were often framed by hand and never engineered for slope, we routinely find ponded sections that have been soaking into the decking for years. We address that in the rebuild by adding tapered insulation or cricket framing, not by layering another coat over a failing deck.

ADUs, Shops, and Garages

Detached structures are their own job. A shop roof off a long driveway needs different access planning, different material staging, and often a separate permit path if the property sits on a county island. We quote the main house and the outbuilding as one project but scope them separately, so you know exactly what each roof costs and what the access adds.

Trusted Brands We Service in Pasadena

You should never have to buy a shingle because it’s what one contractor happens to stock. That’s why we carry relationships with seven manufacturers and let the Pasadena job tell us what to recommend. On a steep Craftsman roof in Bungalow Heaven, a dimensional shingle from GAF or Atlas gives you the shadow-line depth that suits the house. On a mid-century flat roof or a low pitch where architectural shingles aren’t right, we’ll talk materials that actually perform. Tamko’s Heritage line is a solid Pasadena fit for homeowners who want architectural depth without the premium of designer lines. We also service CertainTeed, Owens Corning, IKO, and Boral. For Pasadena clients, that means material selection follows your roof’s geometry, your tree exposure, and your budget. Not our warehouse. Your roof, your material choice.

Common Roof Replacement Problems We See in Pasadena Homes

• Oak and deodar debris in valleys and gutters. The canopy over old Pasadena neighborhoods is beautiful and relentless. Needles and leaves pack into valleys, hold moisture against shingles and flashing, and abrade the granule surface, and a new roof that doesn’t address limb clearance and gutter detailing will start failing the first fall.
• Original skip sheathing under old roofs. The 1910s and 1920s framing in Pasadena often has spaced boards, not solid decking. Modern shingles need a solid nail surface, so a straight tear-off without re-decking leaves you with a roof that won’t meet code and won’t hold fasteners properly.
• Santa Ana wind damage on old asphalt. Dry winds each fall test every edge and ridge. On older roofs, those winds lift weakened shingles and break the seal strips. On an acreage lot with full wind exposure, we see more edge and rake damage than on sheltered streets.
• Open-lot drainage pushing water against fascia. Flat or poorly graded land sends runoff back toward the house. Over time, that wicks under the drip edge and rots decking at the eave line. A replacement that skips the drainage conversation just rebuilds on a foundation of water.
