Trusted Roofing Company for Woodland Hills Homeowners
Finding a Roofing Company in Woodland Hills you can actually trust shouldn’t feel like a gamble. At Mercer Roofing Co Woodland Hills, we’ve built our entire business around removing that uncertainty. Before any technician steps onto your property, you’ll have their name and photo on your phone. When they knock, they’ll show a photo ID badge. And before a single nail is driven, you’ll have a written price in hand. That’s how a roofing company should operate – and it’s how we’ve done it since we were founded in 2000 as part of the Threshold Group family. Call (341) 217-2677 and you’ll reach a live person, not a voicemail, any hour of the day or night.
Roofing Company - Woodland Hills knows this area has its own roofing realities. Santa Ana winds hit the hillsides hard. Summer heat bakes shingles on homes in Walnut Acres and south of the Blvd. And the marine layer that rolls through in June keeps northwest-facing roofs damp for weeks. We know these conditions because we work in them every day – on the flat lots in the flats, the steep pitches above Mulholland, and the older construction throughout the Warner Center area.
Roofing Contractor
A Roofing Contractor is the licensed professional who installs, repairs, and maintains the entire roofing system on your home or building – not just the shingles you see from the street, but the underlayment, flashing, decking, and ventilation underneath. You need one when a repair is beyond a simple patch, when you’re planning an installation, or when you want a trained eye to tell you exactly what’s going on up there. Mercer Roofing Co Woodland Hills provides full roofing contractor services throughout the San Fernando Valley, and every job starts with a written price before any work begins.
Repairs and Upgrades
Most of the calls we take in Woodland Hills start with a leak or a missing shingle after a wind event. We make the repair, but we also look at what caused it – which is what separates a real contractor from someone with a ladder and a nail gun.
Full-System Knowledge
A roof is more than shingles. Flashing, the metal that seals joints around chimneys and skylights, fails more often than shingles do. Decking, the wood layer beneath everything, rots when moisture gets trapped. We address all of it, and we explain it in plain English.
Styles & brands we work with
Roof Inspection
A Roof Inspection is a methodical, item-by-item evaluation of every component of your roofing system – shingles or tiles, flashing, vents, gutters, skylights, and the attic-side decking – to catch problems before they leak into your living space. You need one when you’re buying or selling a home, after a major storm, or simply because your roof is past its tenth birthday and you want to know what’s really going on. Mercer Roofing Co Woodland Hills performs inspections with the same documentation-first approach we bring to every job. You get written findings, photos, and a written price for any recommended work.
Buying or Selling a Home
In Woodland Hills, a pre-purchase inspection can mean the difference between negotiating a credit and inheriting a $9,000 surprise. We document everything in writing so you have a real negotiating tool, not a handshake and a shrug.
Annual Checkups
An annual inspection catches the small stuff – popped nails, cracked sealant at pipe collars, lifted flashing – before it becomes the big stuff. A $200 inspection that finds a $600 repair now beats a $6,000 interior restoration later.
Commercial Roofing
Commercial Roofing covers flat and low-slope roof systems on warehouses, offices, retail buildings, and multi-unit properties in the Woodland Hills area – buildings that need different materials, different drainage design, and different code requirements than homes. You need it when your building has a flat or near-flat roof, when your current roof is past its service life, or when water is ponding in the middle of your roof after rain. Mercer Roofing Co Woodland Hills provides commercial roofing services for property managers and owners throughout the Warner Center corridor and surrounding business districts.
Flat Roof Systems
Flat commercial roofs live and die by their drainage. In Woodland Hills, where we get bursts of heavy rain between long dry spells, a small ponding issue quickly becomes a roof failure. We specify systems that move water, not hold it.
Building Owners and HOA Boards
We regularly work with commercial property owners and community associations across Woodland Hills and beyond, including those who rely on our Roofing Company in Canoga Park. The written-price model matters even more on a building where a surprise change order can blow a budget by twenty grand.
Metal Roof Installation
Metal Roof Installation is the process of replacing or installing a roof using formed metal panels or shingles – materials like standing-seam steel, aluminum, or stone-coated steel – which commonly last 40 to 70 years and perform well against fire and wind. You need it when you’re building new, when you want a roof you’ll likely never replace again, or when you’re on a hillside in a high-fire zone like the canyons around Woodland Hills. Mercer Roofing Co Woodland Hills installs metal roofs on homes throughout the area, and every installation includes our written guarantee and the 365-Day Done Right Promise.
Wildfire Zone Performance
For homes in the hills of Woodland Hills, Topanga Roofing Company territory, and surrounding canyons, metal offers a Class A fire rating and the ember resistance that composition shingles simply can’t match. We install metal with the underlying details done right: proper underlayment, proper fasteners, proper flashing.
Material and Longevity Numbers
Metal roofs cost more on day one than shingle roofs – often 1.5 to 2 times as much for standing seam – but a properly installed metal roof can outlive three shingle roofs. On a long-term cost-per-year basis, metal frequently wins.
Residential Roofing
Residential Roofing is the full spectrum of work on single-family homes and small multi-family properties: new roof installation, replacement, repair, and maintenance of the shingle, tile, or metal systems that protect your home. You need it when your roof is leaking, when it’s showing age-related wear like curling shingles or granule loss, or when you want to upgrade your home’s curb appeal before selling. Mercer Roofing Co Woodland Hills handles residential roofing across every neighborhood in the Woodland Hills area and nearby Roofing Company in Tarzana service areas, from South of the Blvd estates to the ranch-style homes in the flats.
Shingle Replacement
Most Woodland Hills homes wear composition shingle, and we install manufacturer-recognized shingle brands like GAF, CertainTeed, Owens Corning, and Atlas. The right shingle for your home depends on roof pitch, sun exposure, and your own budget – and we’ll show you options with plain-English explanations, not a catalog toss.
Whole-Roof Replacement
A full replacement is the time to get the details right: new underlayment, new flashing, correct ventilation. We give you a written price for the whole scope before we start, and that price doesn’t change unless you change the scope.
Roof Maintenance
Roof Maintenance is the scheduled, proactive care of your roof – clearing debris, checking and resealing penetrations, tightening flashing, and documenting condition changes year over year – designed to extend the life of your roof and keep the warranty intact. You need it on any roof you plan to keep, because a roof rarely fails all at once; it fails piece by piece over years of ignored small issues. Mercer Roofing Co Woodland Hills offers maintenance plans for homeowners and commercial building owners across the Woodland Hills area.
Debris Removal and Drainage
In Woodland Hills, oak leaves and eucalyptus debris pile up in valleys and against parapet walls. That debris holds moisture against roofing materials for months. We clear it, and we check that downspouts and scuppers are actually moving water away from the building.
Sealant and Flashing Checks
Pipe collars and roof vents are sealed with compounds that crack in the Valley sun. We inspect and reseal these penetrations on a schedule, keeping water out for another season.
Roof Coating
Roof Coating is the application of a liquid-applied membrane – typically acrylic, silicone, or polyurethane – over an existing roof surface to seal small cracks, reflect heat, and extend the life of the roof without a full tear-off. You need it when your roof is mid-life, showing minor cracking or early granule loss, and you want another 10 to 15 years of service. Mercer Roofing Co Woodland Hills applies roof coatings on both residential and commercial properties in Woodland Hills, including flat commercial roofs and low-slope residential sections.
Energy Reflectivity
A reflective coating on a flat or low-slope Woodland Hills roof reduces surface temperatures on hot August afternoons and cuts what gets into the building below. On commercial buildings, that often shows up directly in cooling costs.
When Coating Is Not the Answer
If the decking is soft or the roof is leaking in multiple places, a coating is a bandage. We’ll tell you plainly when a coating makes sense and when you should put that money toward repair instead – and we’ll put it in writing either way.
Free Roof Estimate
A Free Roof Estimate from Mercer Roofing Co Woodland Hills is a written, no-obligation price for your roofing work, delivered after we inspect your roof in person – so you know exactly what the job will cost before you commit. You need one whenever you’re considering any roof work, because a written estimate is the only way to compare options honestly. We encourage every Woodland Hills homeowner to get at least two estimates – and we’re confident ours will be the clearest on the table.
What the Estimate Includes
Your estimate includes line-item pricing for materials, labor, disposal of old materials, and any necessary permits. No allowances. No “we’ll see when we get up there.” We inspect fully, then we price fully.
How to Book One
Call (341) 217-2677. You’ll speak to a live person, day or night. We’ll schedule an inspection at a time that works for you, and you’ll have your written estimate shortly after.

AfterBrands We Service
We work with the shingle brands homeowners in Woodland Hills actually ask for by name. GAF is the most common on the roofs of Woodland Hills, and we install and repair GAF systems regularly – including Timberline architectural shingles, which are overbuilt for the Valley’s sun and wind. CertainTeed is another frequent choice among our customers, especially their Landmark line, which offers a thicker, heavier shingle with strong protection against the Santa Anas. Owens Corning Duration shingles hold up well on the steep pitches in the hills, and Atlas shingles perform strongly in high-wind applications. We also work with Tamko and Boral when the home calls for them – Boral’s tile profiles are common on the higher-end estates south of the Blvd.
Whether you have GAF, CertainTeed, Owens Corning, Atlas, Tamko, Boral, or any other make, we can help. Our technicians are factory-trained on the installation specifications for each brand we service, and we follow those specs to the letter – because that’s what keeps your manufacturer’s warranty intact.
Signs You Need a Pro Right Now
- Water stains spreading on your ceiling. This means water is getting through the roof and has already soaked the decking and possibly the insulation. The stain you see is often smaller than the actual damage above it – by the time it shows, the leak has been active for days or weeks.
- Granules in your gutters or at downspout drains. Shingles shed their protective granule layer as they age, and accumulated granules mean the shingles are breaking down. This is especially common in Woodland Hills after hot summers that bake shingles to the point of premature aging.
- Daylight visible through the attic boards. If you can see daylight from inside your attic, water can get in. That’s not a repair to put off – it’s a direct opening to the weather, and in Woodland Hills winter that means rain entry.
- Curling or lifting shingles after a Santa Ana event. Wind-driven shingles that lift have broken their seal, and once that seal fails, more wind gets under them. A triangle of lifted shingles after one windstorm turns into a missing section after the next.
- Soft or sagging areas on the roof deck. A spongy feel underfoot or a visible sag means the wood decking beneath the shingles has been wet long enough to lose structural strength. This is a safety issue and needs professional evaluation before someone puts a foot through it.
Our Process, Step by Step
- 1
You call, a person answers. (341) 217-2677. Any hour. You tell us what’s going on, and we schedule a site visit at a time that works for you. You’ll get the name and photo of the technician who will be at your door before they arrive.
- 2
The technician arrives, badge out. Your Mercer technician shows up in a clean, marked uniform and presents a photo ID badge at the door. They’re background-checked and identity-verified under the Threshold Standard. No exceptions, on every visit.
- 3
We inspect and document everything. The technician inspects the roof in full – shingles, flashing, ventilation, decking, and the attic side where accessible. We photograph what we find and we show it to you, explaining the condition in plain English.
- 4
You get a written price. Before any work starts, you have a written, line-item price in hand. No work starts without it, ever. And that written price is the price – there are no surprise change orders.
- 5
We do the work, and we back it. The repair or installation is completed by the same technicians you met that morning – no subcontracted mystery crew. Every repair includes a written guarantee, and if it fails, a second visit is free. If it’s not done right within 365 days, we make it right.
How Much Does Roofing Company Cost in Woodland Hills?
Roofing costs in Woodland Hills depend heavily on what the work actually is. A typical roof repair in the area – replacing a few missing shingles, sealing a pipe collar, fixing a small flashing section – runs $300 to $900. A full shingle roof replacement on a standard 1,800-square-foot Woodland Hills ranch home typically lands between $11,000 and $19,000, depending on the shingle brand, the number of roof penetrations, the roof pitch, and whether the decking needs replacement. A metal roof installation on the same home – standing seam or stone-coated steel – usually runs $22,000 to $40,000. Roof coating on a flat or low-slope area runs $4 to $9 per square foot. A commercial roof replacement on a small to mid-size Woodland Hills warehouse starts around $70,000 and rises based on the roof system type and building size.
What affects the price most: roof accessibility, decking condition, existing layers that need removal, the number of skylights, chimneys, and vents, and whether permits are required. You avoid overpaying by getting a written, line-item estimate and comparing it to another written, line-item estimate – our free estimate includes every cost but one glance can tell you if you’re being charged for work you don’t need. Every free estimate from Mercer Roofing Co Woodland Hills includes a full inspection, photos, and a written line-item price. Call (341) 217-2677 to schedule yours.
