We know Inglewood’s housing stock because we’ve worked on it for years. The 1920s-through-1950s single-family homes near the Forum and down toward Morningside Park carry their own set of roofing conditions: original lumber gone brittle, layers of composition stacked over wood shake, and drainage details that were never great to begin with. A roof installed here has to account for all of that. Ours do.

Why Mercer Roofing Co Torrance Is Inglewood’s Preferred Roof Installation Company

Homeowners in Inglewood call us for one reason more than any other: they want to know exactly who is walking up their driveway before that person ever rings the bell. Every Mercer technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. Before a crew member arrives, we send their name and photo to your phone. At the door, they present a photo ID badge and wear a clean, marked uniform. No surprises, no strangers.

We also put every price in writing before any work starts. That includes tear-off, decking replacement if needed, underlayment, flashing, shingles, ventilation, and the permit. The number we give you is the number you pay, unless we find a problem behind the old roof and you approve an add-on in writing first. No change orders dropped on you mid-week. No “we’ll figure it out after we open it up.” We started working this way in 2000, and it’s held up.

Every roof installation we complete in Inglewood carries our 365-Day Done Right Promise. If anything isn’t right within a year, we make it right. That’s a written guarantee, not a handshake.

Roof Ventilation in Inglewood

Roof Ventilation installation in Inglewood is often the difference between a roof that lasts 15 years and one that fails in 10. Inglewood’s summer sun beats down on attic spaces that were rarely ventilated to modern standards, and heat that builds up under the decking cooks shingles from below. Granule loss accelerates, and the attic becomes an oven that pushes heat into the living space and drives up cooling bills. A properly calculated intake-and-exhaust system, usually soffit vents paired with a ridge vent, keeps the attic temperature close to outdoor ambient and extends the life of the shingle itself. Most Inglewood roof ventilation installations run $800 to $2,400 depending on attic size and whether we’re adding just a ridge vent or a full continuous soffit system.

When an older Inglewood roof needs it

Homes built before anyone cared about airflow, particularly the 1930s and 1940s bungalows around Morningside Park and the neighborhoods east of Prairie Avenue, often have no intake ventilation at all. Soffits are boarded over or never cut. If your upstairs rooms run noticeably hotter than downstairs in July, or you see rust on nail heads in the attic, the fix usually starts with ventilation. We calculate net free vent area per the International Residential Code and install balanced intake and exhaust so the system actually moves air. A roof without balance doesn’t vent; it just leaks energy.

What it costs and why it matters

Expect $800 on the low end for a ridge vent added to an existing composition shingle roof, and up to $2,400 when we’re cutting in soffit vents, installing baffles, and adding a thermostat-controlled power vent for an attic with no natural exhaust path. Skimping on ventilation often voids shingle warranty coverage from manufacturers like Owens Corning and Atlas, which is reason enough to get it right during the roof installation rather than bolting it on later.

Roof Flashing Installation in Inglewood

Roof Flashing Installation in Inglewood is where water wins or loses. Flashing is the metal, typically galvanized steel, aluminum, or copper, that seals the joints where the roof meets a wall, chimney, vent pipe, or valley. On Inglewood’s older homes, we routinely find original flashing that’s 60 or 70 years old, paper-thin from corrosion, and sealed with tar that cracked a decade ago. When we install a new roof, we replace every piece of flashing, not just the pieces that look bad. Most Inglewood roof flashing installation work runs $500 to $2,000 as part of a full roof replacement, depending on how many penetrations and valleys the home has.

Parapet walls and low-slope roofs

Newer multi-story apartment buildings and infill construction in Inglewood often use flat or low-slope torch-down roofing. The failure point is almost always the parapet wall, where original installers skipped proper counter-flashing or sealed it inadequately. Water gets behind the membrane, travels down the wall, and shows up inside units two floors below the actual leak. We flash parapets with a two-piece system: base flashing under the membrane and counter-flashing cut into the wall. One piece does not do the job.

Valleys on older Spanish Colonial homes

The Spanish Colonial and Mediterranean-revival homes scattered through Inglewood near Centinela Avenue and Hyde Park Boulevard have one consistent weak spot: valley flashing. When a valley is lined with a single sheet of metal instead of a woven or closed-cut system, leaves and debris choke it, and water overflows into the decking. We install open metal valleys with a 24-gauge minimum and appropriate underlayment so the valley moves water off the roof instead of into the house.

Trusted Brands We Service in Inglewood

We install and repair roofs using manufacturer-recognized shingle brands that hold up under Inglewood’s specific conditions. That includes Owens Corning Duration and Oakridge lines, Atlas Pinnacle Pristine, and IKO Cambridge architectural shingles. For cool roof compliance on Inglewood permit-required projects, we specify reflective shingle colors and coatings from these same lines, so the product meets the energy code without sacrificing looks. We order directly from regional suppliers and stage materials at local yards, which means fewer delays for Inglewood customers and faster turnaround when a roof installation is already underway. You’re not waiting on a pallet from two states away.

Common Roof Installation Problems We See in Inglewood Homes

• Hidden wood shake under multiple composition layers: In the Morningside Park area specifically, homes built in the 1930s and 1940s often still have original wood shake roofs buried under two or three layers of later composition shingles. The shake rots from trapped moisture, and by the time leaks show on the ceiling, the decking underneath has been failing for years. A full tear-off is the only way to find and fix it.
• Rotted decking at valleys and around penetrations: Inglewood’s older homes were flashed with materials that simply aren’t adequate for 70 years of weather. When we pull back the old roofing, we frequently find decking so far gone that a screwdriver goes through it with a push. We replace decking per code, in sections, and you see a written line-item price for it before we order lumber.
• Santa Ana wind uplift at eaves and rakes: When the dry winds come through the passes and hit Inglewood in September and October, the first thing to lift is the shingle at the roof edge where drip edge was never installed or the starter strip was nailed too high. We install drip edge on every edge, every time, and set starter strip so the sealant strip locks into the first course.
• Failed torch-down on newer infill buildings: Inglewood’s recent multi-unit additions and accessory dwelling units often have flat or very low-slope roofs with torch-down membrane. When the original installer skimped on parapet flashing or drain sealing, the roof fails in five years instead of twenty. We see this constantly, and the repair is always the same: open it up, flash it properly, and test the drains before we walk away.
