Overview
A roof inspection from QRS is a free, professional roof inspection service for homes across Los Angeles and Orange County. As a local roof inspection company, we send a roofer, not a salesperson, so the visit is a roofing consultation backed by real roofing expertise. Every roof type has its own weak points, so the roofer adapts the inspection to what’s on your house; the sections below show what we check on shingle, tile and flat roofs. Every roof also gets a close look at the flashings where it meets walls, chimneys, skylights and vents, and at the edges and any gutters that carry water away. We photograph each finding, which lets you judge the roof’s condition with your own eyes.
It’s worth booking one when you’re buying or selling a home, after a storm, strong Santa Ana winds or a noticeable earthquake, when an older roof leaves you unsure of its condition, or before choosing between a roof repair and a roof replacement. The visit ends with one recommendation: repair, monitor, maintain or replace, and because we handle roof inspection and repair, the roofer who found the problem can explain the fix. Sometimes the honest answer is that your roof is fine for now, and we’ll say so. There’s no deposit, you pay after the visit, and you’re under no obligation to hire us for any work.
Where leaks start
Where a home’s roof leaks
Water rarely comes in where the ceiling stain shows. It starts at a detail like these, then runs along the underlayment or a rafter before it drips.
Shingle roofs
Shingle Roof Inspection
Shingles show their age in ways a trained eye can read. We look for granule loss, blistering, curling and cracked or brittle tabs, then check the places shingle roofs tend to leak. We also note the intake and exhaust vents, because a poorly ventilated attic ages shingles from underneath.
If a few shingles or a flashing need work, a targeted shingle roof repair is usually the answer. If a shingle roof replacement is the honest call, you’ll see the photos behind that advice.
Shingle wear
Granule loss, blisters, curling and brittle tabs, especially on the sunniest slopes.Lifted and missing tabs
Lifted, creased or missing tabs, broken seal strips and nail pops.Pipe boots, vents and flashings
Step and counter flashing, vent collars and pipe boots, where shingle roofs most often leak.Valleys and edges
Valleys, hip and ridge caps and the drip edge.
Tile roofs
Tile Roof Inspection
Inspecting a tile roof takes more care than most. Tiles crack underfoot, so we step only where tiles overlap and are supported, and the part that matters most, the underlayment, is mostly hidden. On clay tile, we look closely for hairline cracks and shifted pieces; on concrete, for surfaces worn thin and porous.
A tile roof can look sound from the street even when its underlayment is near the end. If the evidence points that way, a tile lift & relay is usually the fix, and smaller problems are a tile roof repair.
Tiles
Cracks, slips and gaps, including loose ridge and hip tiles.Ridge mortar and bird stops
Crumbling mortar, missing bird stops and open eave closures.Valleys, flashings and vents
Valley metal, wall and chimney flashings and vent penetrations.Visible underlayment
The underlayment wherever it can be seen, plus stains and leak history.
Flat roofs
Flat Roof Inspection
A flat roof keeps its problems out of sight. From the ground you can’t see the blister that’s about to crack, the lap lifting at a parapet or the dirt ring where water sat for days after the last storm. Water that sits long after rain points to low spots, clogged drains or not enough slope, so we note where it collects and why.
If you’ve noticed a ceiling stain, point it out, because it helps us trace water back to its source. When work is needed, you’ll know whether a flat roof repair will do or it’s time to plan a flat roof replacement.
Membrane and seams
Blisters, splits and worn areas, and the seams and laps across the whole surface.Ponding
Ponding marks and low spots where water sits after rain.Parapets and flashings
Parapet walls and caps, wall flashings, HVAC curbs, vents and skylights.Drains
Drains, scuppers and downspouts, checked to make sure they’re clear.
Our Process
What happens during a roof inspection
Tell us what you’ve noticed
A stain, a slipped tile, missing shingles, a recent storm or a home sale: knowing why you called helps the roofer focus on the right areas first.
A roofer checks the whole roof
The roofer looks at the roof covering, flashings, penetrations, edges and gutters, with drone footage from our RoofScan 360® evaluation. On tile, we step only where tiles are supported, so the inspection doesn’t leave new cracks behind.
Photos explained in plain English
We go through the photos with you and sort normal wear from real problems and from things that can safely wait.
One clear next step
Repair, monitor, maintain or replace. If you want us to do the work, a written scope and price follow.

I was recommended this roofing company by a friend, and I’m really glad I went with them. I had a problem with water leaking into my attic from the flashing around the chimney, and the team was very helpful from the start. Tony was the roofer working with me, and he was always professional and friendly. He took care of resealing the flashing and chimney, which made the leak much better right away. He kept in touch with me after the work, and now we’re working on sealing the chimney even more to make sure everything is perfect. I feel confident that the team will get everything fixed up right. Based on my experience so far, I’d definitely give them five stars. Thanks to everyone there for their hard work!
Kelsey Breadmont4 months ago · GoogleI was looking to replace my shingles roof in Encino and contacted a few roofing companies in the neighborhood.

I will definitely recommend to friends.
Jose Linareza month ago · GoogleWe trusted Tony for a full roof replacement. They showed up early each day, worked efficiently, and kept us updated. I appreciated the patience in answering our concerns about materials and warranty. The new roof looks sharp and already makes the home feel more energy-efficient.

Why Choose QRS for a Roof Inspection?
An inspection is only useful if you can trust it, so ours is built to inform you, not to sell to you.
A roofer’s read on your roof
The inspection is done by a roofer who knows how shingle, tile and flat roofs are built and how each one tends to fail, backed by our standing as a licensed California contractor since 2020.
Photos you can keep and share
The photos let you review the findings later, show them to family or a buyer, and compare your options without relying on memory.
One clear next step
If work makes sense, a written scope and price follow. If the roof only needs watching, that’s what we’ll recommend, with no push toward a bigger job.
Checks made for your roof type
We look at the details each roof depends on, from seal strips and nail pops to bird stops, ridge mortar and roof drains.

Wherever you are, it starts the same way: a roofer looks at the roof, you get photos of what we find, and a written scope and price comes before any work.
Roof inspection questions, answered
Straight answers about roof inspection.
What do roof inspectors look for?
The roofing itself (worn, cracked, slipped or missing shingles and tiles, bare asphalt, blisters and open seams on flat roofs), the flashings at walls, chimneys, skylights and vents, the valleys and edges, signs of water getting in, and how the roof drains and is ventilated. We photograph each finding, explain it in plain English and give you one clear next step: repair, monitor, maintain or replace.
Is the roof inspection really free?
Yes. For homes, our roofer-led roof evaluation is free, with no obligation and nothing to pay up front. We use drone footage to see the roof’s condition, explain what we find in plain English and give you a clear next step. The optional $199 Roof Check is a separate tune-up visit, and the $199 is credited toward a repair or replacement if you move forward.
What do I get after the roof evaluation?
Photos of what we found, a plain-English explanation of what they show and one clear recommendation: repair, monitor, maintain or replace. If work is needed, you get a written scope and price before anything starts, with no pressure to decide on the spot.
Do you do roof inspection and repair?
Yes. The roofer who inspects your roof can explain how a problem would be fixed, and if you want us to do the work, you get a written scope and price first. Small issues often go to roof repair; you’re never obliged to hire us after the evaluation.
Is QRS a roof inspection company near me?
We inspect roofs across Los Angeles and Orange County, plus parts of Riverside and San Bernardino Counties, from offices in West Hollywood, Woodland Hills and Vernon. Our service area page lets you check your ZIP code.
I’m buying a home. Is a general home inspection enough for the roof?
A general home inspection looks at the whole house, and the roof is one item on a long list. A roofer’s evaluation focuses on the roof alone, with photos of the roofing, flashings and vents. That matters most on tile, which can look sound from the street even when its underlayment is near the end, and on homes with flat sections that are easy to miss from the ground.
Can you tell how much life my roof has left?
We can tell you what condition it’s in and what kind of wear to expect next, but nobody can promise an exact number of years. On tile, most of the underlayment is hidden, so we judge it from the areas we can see, the roof’s history and signs like leaks or stains. The photos help you plan ahead instead of reacting to a leak.
Is a free roof evaluation worth it after a storm if nothing is leaking?
Often, yes. High winds and heavy rain can loosen flashings, shift tiles and break shingle seals without an immediate leak, and a noticeable earthquake can crack ridge mortar and nudge tiles out of place. Those weak spots tend to give way in the next storm. If water is already coming in, our emergency roof repair page explains how we handle it.
Do I have to hire you for the work after the roof evaluation?
No. The roof evaluation is free: you see the photos and decide what’s next, with no pressure either way. If you’d like us to do the work, you’ll get a written scope and price first.
What should I tell you before the roof evaluation?
Anything you’ve noticed: stains, drips, roofing pieces in the yard, past repairs, the roof’s age if you know it, a recent storm or an upcoming sale. That context points the roofer to likely trouble spots, and the rest of the roof still gets checked.
I’m selling my home. Should I have the roof inspected first?
It can help. Knowing the roof’s condition before you list gives you time to handle small repairs on your own schedule, plus photos you can share with buyers. That makes the roof less likely to become a surprise late in the sale.
How is a free roof evaluation different from a maintenance plan?
A roof evaluation is one visit that shows where your roof stands today. A roof maintenance plan is set up after a free roof evaluation, around your roof’s type, age and condition, with visits on the schedule in your plan and a photo report after each one. Anything beyond the plan gets a written price before work.
Do you inspect roofs on commercial buildings?
Yes. Offices, retail centers, warehouses, churches and other commercial buildings get a roofer-led, photo-documented roof survey of the membrane, drains, flashings and equipment curbs. Ongoing care is covered on our commercial inspection & maintenance page.
