Fast, Reliable Roof Replacement Across Rosemead
Replacing a roof on a Rosemead home usually costs between $12,000 and $28,000 for a full tear-off, depending on size, pitch, and how many old layers need to come off. Most mid-century ranch homes in the 91770 and 91771 ZIP codes run closer to the middle of that range, with architectural shingles being the most common choice. Call (833) 589-7971 to schedule an inspection, and we’ll walk the roof with you, show you what we found, and put a written number in front of you before you commit to anything.
We’ve spent enough time in Rosemead to know that a 1958 roof in the flats of 91770 rarely gives up its secrets from the driveway. You have to get up there, look at the transitions, check the decking from the attic, and understand what sixty years of San Gabriel Valley sun does to felt and flashing. That’s the work we do before we ever hand you a bid.
Why Hollywood Roofing Co Is Rosemead’s Preferred Roof Replacement Company
Our reputation in Rosemead has been built the slow way, one tear-off at a time. Homeowners along Garvey Avenue, in the neighborhoods around Rosemead Park, and through the 91772 streets north of Valley Boulevard have called us because a neighbor watched our crew work and liked what they saw. We don’t rush a job to get to the next one, and we don’t hide behind subcontractors doing the actual installation.
Roland Vega set the standard for how we operate: inspect first, quote in writing, and never start cutting until the homeowner understands exactly what’s coming off and what’s going back on. That approach matters even more in Rosemead, where a roof replacement often uncovers things nobody expected. Multiple layers of old shingles. Soft decking at the flat-to-pitch transition. Flashing that was never done right in the first place. We handle it without drama, and without surprise invoices.
Because we work across seven major brands, we’re not trying to push you into whatever single product our supplier happens to stock. GAF, CertainTeed, Owens Corning, and Boral are all options we install, and the recommendation you get is based on your Rosemead home’s roofline, slope, and sun exposure, not on a rebate we’re chasing.
Styles & brands we work with






Roof Installation in Rosemead
Roof Installation for Rosemead homeowners typically means one of two situations: a full tear-off and replacement on an existing home, or a brand-new roof on an addition, ADU, or new construction project. Full tear-offs on a standard 1,200 to 1,800 square foot ranch in Rosemead generally land between $12,000 and $22,000, while new-construction and addition roof installation runs on the lower end of that scale if the framing and decking are already in place, but can climb past $30,000 when structural work is involved.
Full Tear-Off Replacement
Most Rosemead homes built in the 1950s and 60s have never had a proper tear-off. Someone laid a second layer of shingles over the first, maybe a third, and now the decking underneath is rotting where moisture got trapped. We remove every layer, expose the deck, and replace anything that’s delaminated before the new roof goes down. This is the cleanest way to install, and it’s the only way to actually see what condition the framing is in.
New Construction and Additions
Rosemead has a steady stream of ADU permits and addition projects, especially on lots where the original ranch home left room in the back. When we install on new framing, we coordinate directly with the general contractor, make sure the roof meets current Title 24 energy code, and install to manufacturer spec so the warranty stays intact. If you’re adding a flat-roof section, we’ll detail the transition to any existing shingle field properly from day one, because we know what happens five years later when that junction is done with tar and hope.
Roof Replacement Contractor in Rosemead
A Roof Replacement Contractor in Rosemead has to understand what sixty years of sun, rain, and shortcuts do to a ranch home’s roof system. We’ve replaced roofs in every part of this city, from the 91770 flats south of the 60 freeway to the older streets around Savanna High School, and we know the failure patterns here. A typical full replacement on a Rosemead ranch, with tear-off of one or two old layers and new architectural shingles, runs $13,000 to $24,000. Homes with multiple layers, rotted decking, or flat sections that need new membrane will push toward $28,000 or more.
Decking Inspection Before the Bid
We inspect the deck from inside the attic before we quote. That means pulling back insulation at the eaves, looking at the underside of the sheathing, and checking for water stains around vent penetrations. A bid that skips this step is a guess, and on a Rosemead home with two layers of old shingles, that guess is usually wrong. We’d rather tell you the full number upfront than “discover” rot after the shingles are off, which is why we write a decking allowance into every contract and price any additional sheets before we cut them.
Flat Roof Sections and Transitions
Those low-slope built-up or gravel sections over family room additions are where Rosemead roofs fail first. The original transition to the main shingle field was often just tar, no membrane, no flashing, and it’s been leaking for years before anyone notices the stain on the ceiling. When we replace the roof, we rebuild that junction properly: peel-and-stick membrane running up the pitch side, new drip edge, and shingles that shed water onto the flat section instead of under it.
Trusted Brands We Service in Rosemead
We install materials from GAF, CertainTeed, Owens Corning, and Boral, among others, which means you get a real choice instead of whatever one brand the contractor happens to have a relationship with. For Rosemead’s intense UV exposure, we often recommend a heavier architectural shingle with a high reflective rating for south- and west-facing slopes. If you’re budget-conscious, a dependable mid-tier shingle does fine here as long as the underlayment and flashing are done right. Seven leading brands. One honest recommendation, matched to your home and your budget, not to our supplier’s incentives.

AfterCommon Roof Replacement Problems We See in Rosemead Homes
- Failed flat-to-pitch transitions. The low-slope section over the addition meets the shingle roof at a junction that was sealed with tar fifty years ago. Tar fails. Water gets in. By the time you see a ceiling stain, the decking around that junction is usually soft. We inspect this junction first on every Rosemead bid, because it’s the most common source of hidden damage here.
- Hidden decking rot under multiple shingle layers. Rosemead’s original ranch homes were often re-roofed by laying new shingles over old ones, sometimes twice. Two or three layers trap moisture and hide delaminated plywood until tear-off day. Our attic inspection catches most of it before we quote, and our contract includes a written decking allowance priced per sheet, approved in writing before we replace it.
- Sun-scorched south and west slopes. The San Gabriel Valley sun cooks these slopes year-round, and the felt underlayment under a roof’s south and west sides often fails before the shingles do. A partial overlay that leaves that failed underlayment in place will leak within a season or two. Full tear-off is usually the honest answer here.
- Original wood shingle or shake roofs at end of life. Some of Rosemead’s oldest homes still have original wood shingle roofs patched with whatever was on hand. These have long outlived their design life, and installing over them is never the right call. We remove them completely, inspect the rafters, and build the new roof from a solid deck up.
Pricing for Roof Replacement in Rosemead, CA
Here’s what Rosemead homeowners should expect to pay. A straightforward tear-off and re-shingle on a 1,200 square foot ranch typically runs $12,000 to $18,000. Larger homes, or those with steep pitches and limited access, land between $18,000 and $24,000. Add a flat-roof section over an addition and you’re looking at another $2,000 to $5,000 depending on the membrane system. If your roof has multiple layers to remove, heavy decking repair, or needs new fascia and drip edge throughout, the project can reach $28,000 to $32,000. We give free estimates, and the number we quote is the number we build to, with any change priced and approved in writing before we touch it. Call (833) 589-7971 to get your roof walked and priced.

FAQs About Roof Replacement in Rosemead
Yes, we replace the shingle field and the flat section in the same project, and we did exactly that on a 1958 ranch in the 91770 flats where the addition’s built-up section tied into the main hip roof with nothing but tar. We rebuilt the decking at the junction, ran peel-and-stick membrane up the pitch side, and set new drip edge before laying architectural shingles. The flat section got a new membrane system rated for Rosemead’s heat. One crew, one job, one warranty. Call (833) 589-7971 to have us look at your transition detail.
Mostly, yes, and the main one is nailing pattern and decking condition. If the decking is deteriorated or the existing roof has too many layers, the building official will require a full tear-off and likely new plywood or OSB to meet current shear standards. Rosemead also enforces Title 24 cool-roof requirements for certain replacement situations. We pull permits on every replacement, and we’ll tell you before we start what the inspector is going to look for. Call (833) 589-7971 for an exact picture on your street.
Put the decking allowances side by side first. On a 1950s-60s Rosemead home, the wildcard is the condition of the sheathing under multiple old layers, and a bid that doesn’t address it will change mid-job. Look at whether the contractor inspected the attic, whether the bid includes the flat-to-pitch transition detail, and whether the underlayment is called out by brand and spec. Don’t compare just the shingle line; compare the scope. Call (833) 589-7971 and we’ll give you a line-item quote you can hold against the other one.
Because those slopes take the full force of the San Gabriel Valley sun, and summer temperatures above 100°F cook the asphalt shingle granules and the felt underneath. A south slope can look fifteen years older than the north slope on the same roof. That’s why we often recommend a higher-rated architectural shingle, and why the underlayment on those slopes matters as much as the shingle itself. Call (833) 589-7971 and we’ll tell you what’s happening on your specific exposures.
Yes, we match the profile and color family of the original roof as closely as current products allow, and we’ll show you samples on your roof before you decide. For most Rosemead ranch homes, that means an architectural shingle in a neutral tone that works with the brick or stucco facade. If you want a more authentic period look, we can discuss specific product lines from our brand portfolio. Call (833) 589-7971 to schedule a time to see samples in Rosemead daylight.
