AfterNew Construction in Woodland Hills, CA
New construction roofing in Woodland Hills means installing a roof on a home that’s being built from the ground up, not replacing one that’s already there. This is a different job than a Roof Replacement & Installation in Woodland Hills because there’s no old roof to tear off, no hidden decking surprises from decades of weather, and no existing structure limiting your material choices. We start fresh, which means we can build the roof system exactly right the first time: proper underlayment, correct flashing at every penetration, and shingles installed to manufacturer specifications from day one. If you’re building in Woodland Hills and need a roof that will hold up to our summer heat, winter rain, and the occasional Santa Ana wind event, call Mercer Roofing Co Woodland Hills at (341) 217-2677 and we’ll walk you through exactly what your project needs.
Mercer Roofing Co Woodland Hills has been roofing homes since 2000 as part of the Threshold Group family. Every new construction roof we install carries our 365-Day Done Right Promise in writing. That means if something isn’t right within a year, we make it right. No fine print, no phone tag, no “that’s normal settling.” You get a written guarantee on every new construction roof we install, and a written price before any work begins.
When You Need New Construction
New construction roofing in Woodland Hills isn’t just for custom home builds. Here are the situations where we typically get called:
- You’re building a new home or ADU. Accessory dwelling units are common in Woodland Hills, especially in neighborhoods south of Ventura Boulevard where lots allow for them. A new structure needs a roof installed to current California building code, including Title 24 cool roof requirements where applicable.
- You’re adding a second story or a major addition. When the footprint of your home changes, the roof system has to be designed and installed as new construction, not patched onto the old roof. The junction between old and new is where leaks happen if it’s not done with care.
- You’re building a detached garage, workshop, or pool house. These structures need the same quality roof as the main house. We regularly install roofs on detached structures in Woodland Hills, and we treat them with the same written guarantee as any full home roof.
- Your general contractor needs a roofing subcontractor. If you’re a GC working in Woodland Hills, Tarzana, Calabasas, or anywhere in the west San Fernando Valley, we coordinate directly with your schedule. Our technicians arrive with photo ID badges, so your clients know exactly who is on their property.
- A previous roof was installed incorrectly on new construction. We do see this. Sometimes a builder’s roofer cuts corners on underlayment or flashing, and the homeowner finds out during the first rainy season. We fix it properly and document everything in writing.
- You’re planning a new build and want the roof budgeted accurately. We provide line-item written pricing before work starts, so you’re not guessing at what the roof will cost when you’re planning the whole project.
Our New Construction Process
New construction roofing has a different sequence than reroofing. Here’s how we work on a new build in Woodland Hills:
- Site visit and roof plan review. We walk the job with you or your GC, review the roof plan if you have one, and talk through material options. We’ll give you our honest read on what will work for your specific roofline. Woodland Hills homes range from mid-century ranches to newer two-story builds, and each roofline has different needs.
- Written price, no surprises. Before any work starts, you get a written price. It includes materials, labor, underlayment, flashing, ventilation, and cleanup. If we identify a potential issue mid-job, like roof decking that needs adjustment, we tell you before we touch it. No surprise invoices at the end.
- Decking and underlayment installation. We install the roof deck if it’s not already in place, then lay a high-quality synthetic underlayment. In Woodland Hills, this underlayment is your last line of defense against wind-driven rain, so we don’t skip or skimp here.
- Flashing at every penetration and transition. Chimneys, skylights, vents, and roof-to-wall transitions all get proper flashing. This is where most leaks originate on any roof, and on new construction we get to do it right from the start rather than retrofitting.
- Shingle installation to manufacturer spec. We install shingles from manufacturer-recognized brands including GAF, CertainTeed, and Owens Corning, always following the manufacturer’s installation instructions exactly. That’s what keeps your warranty valid and the roof performing.
- Final walkthrough and written guarantee. We walk the roof with you, document what was installed, and hand you a written 365-Day Done Right Promise. If anything isn’t right within a year, we come back and make it right at no cost to you.
New Construction Pricing in Woodland Hills
New construction roofing in Woodland Hills typically runs from $6.50 to $12.00 per square foot installed, depending on the shingle brand, roof pitch, and the complexity of the roofline. Here’s what that looks like for common roof sizes:
| Roof Size | Typical Range (Architectural Shingles) | Typical Range (Premium Shingles) |
|---|---|---|
| 1,500 sq ft | $9,750 – $13,500 | $13,500 – $18,000 |
| 2,000 sq ft | $13,000 – $18,000 | $18,000 – $24,000 |
| 2,500 sq ft | $16,250 – $22,500 | $22,500 – $30,000 |
| 3,000 sq ft | $19,500 – $27,000 | $27,000 – $36,000 |
What affects your price:
- Roof pitch. Steeper roofs cost more because they take longer to install safely and require more equipment. A 4/12 pitch is straightforward. A 10/12 pitch on a Woodland Hills hillside home takes more time and care.
- Number of penetrations. Every chimney, skylight, vent pipe, and roof-to-wall transition adds flashing work. A complex roofline with six penetrations costs more than a simple gable roof with two.
- Shingle brand and line. We install Atlas, Tamko, Boral, GAF, CertainTeed, Owens Corning, and IKO. A premium shingle like Boral’s stone-coated steel or CertainTeed’s Grand Manor will run higher than a standard architectural shingle from Atlas or Tamko.
- Underlayment choice. Standard synthetic underlayment is included in our base price. If you want a premium ice-and-water shield or a high-temperature rated underlayment for our summer heat, that adds cost.
- Decking condition. On new construction, the decking should be new, but sometimes we arrive to find OSB that’s been sitting out in weather and needs replacement. We flag it and give you a written price for the fix before we proceed.
Every new construction roof quote from Mercer Roofing Co Woodland Hills includes a written price before work starts.

No obligation, no pressure, just a real price from a roofer who shows up with a photo ID badge and a name you already know before we arrive.

FAQs – New Construction
How much does new construction roofing cost in Woodland Hills?
New construction roofing in Woodland Hills typically costs between $6.50 and $12.00 per square foot installed, which puts most full roofs in the $9,750 to $36,000 range depending on size, pitch, and shingle brand. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and every quote is a written price before any work starts. Call (341) 217-2677 for a site visit and a real number for your specific project.
Can you install a roof on a new ADU in Woodland Hills?
Yes, we install roofs on ADUs throughout Woodland Hills, and we’re familiar with the California Title 24 cool roof requirements that apply to accessory dwelling units in Los Angeles County. We’ll help you choose shingles that meet the energy code for your zone, and the roof is covered by our 365-Day Done Right Promise in writing. Call (341) 217-2677 to talk about your ADU project.
Is new construction roofing different from reroofing?
Yes, new construction roofing is different from reroofing because there’s no tear-off involved and no existing roof limiting your choices. It also means we install the roof deck, underlayment, flashing, and shingles as one integrated system in the correct order, which gives you a cleaner result than most reroofs. The downside is that there’s no old roof to protect the structure while we work, so scheduling around weather matters. Call (341) 217-2677 and we’ll talk through what’s right for your build.
How long does new construction roofing take in Woodland Hills?
Most new construction roofing in Woodland Hills takes 2 to 5 working days for a standard single-family home, depending on roof size, pitch, and complexity. An ADU or detached garage can often be done in a single day. We’ll give you a written timeline along with your written price, and if the weather shifts, we’ll call you before we adjust the schedule. Call (341) 217-2677 and we’ll give you a realistic timeline for your project.
Do you work with general contractors and builders?
Yes, we regularly work as the roofing subcontractor for general contractors and builders in Woodland Hills, Tarzana, Calabasas, and the surrounding west San Fernando Valley. We coordinate with your schedule, and every Mercer technician arrives in a clean uniform with a photo ID badge, so you can tell your clients exactly who is coming and when. Call (341) 217-2677 to set up a GC account and get written pricing for your next build.
Why Woodland Hills Homeowners Choose Mercer Roofing
Here’s the thing about new construction roofing: the roofer you choose matters more than on a reroof, because you don’t get a second chance to get the underlayment right. Once the shingles are on, the underlayment is hidden. If it was installed wrong, the first sign is a ceiling stain two years later.
That’s why we do what we do differently. Every Mercer Roofing Co Woodland Hills technician is background-checked, identity-verified, and dispatched under the Threshold Standard. The Threshold Verified framework means each independently owned location is contractually held to quality requirements that go beyond what most roofers will commit to. Before a technician arrives at your property, we send their name and photo. When they knock on your door, they present a photo ID badge. You don’t have to wonder who’s on your roof.
