Quick answer
A roof inspection is a close check of your roof's surface, flashing, vents, edges and drainage, plus the attic and roof deck where leaks and rot show up first. A good inspector takes photos and explains what they found in plain language. Get one when buying or selling a home, after a windstorm or heavy rain, or every few years as a roof ages.
Why a roof inspection is worth an hour of your time
Most roof problems start small and stay hidden. A lifted shingle, a cracked tile or a pipe boot that has dried out in the sun can let water in for months before you see a stain on the ceiling. By then the damage is usually in the deck and insulation, not just the roofing.
An inspection catches those problems while they're still cheap to fix. It also gives you a clear picture of how much life your roof has left, which matters whether you're planning a budget, selling a house or trying to decide between a repair and a new roof.
Here in the High Desert, roofs take a beating from strong sun, big day-to-night temperature swings and gusty wind. Those conditions wear materials faster than a mild coastal climate does, so a regular look is a smart habit, not an extra.
What gets checked on the roof itself
A thorough inspector walks the roof when it's safe to do so, and looks at it from the ground and ladder when it isn't. On a shingle roof, that means checking for:
- Curling, cracking, blistering or missing shingles
- Granule loss, which shows up as bare or shiny patches
- Lifted tabs and broken seals from wind
- Soft or spongy spots that point to a weak deck underneath
- Ridge caps, hips and valleys, where water concentrates
Tile roofs get a different kind of look. The inspector checks for cracked, slipped or missing tiles, loose ridge and hip pieces, and signs that the underlayment beneath the tile is wearing out. On tile, where you step matters, because careless foot traffic can crack tiles during the inspection itself. If your tile roof has a leak, our post on why tile roofs leak explains what's usually going on underneath.
Flat and low-slope sections, like patio covers and additions, get checked for ponding water, open seams and worn edges.
Inside the attic: where the real story shows up
The attic is often more honest than the roof. From inside, an inspector can see things that are invisible from above:
- Water stains, dark streaks or dried drip marks on the underside of the deck
- Daylight coming through where it shouldn't
- Damp or compressed insulation
- Rot, delamination or sagging in the sheathing
- Signs of poor ventilation, like excess heat, moisture or rusted nail tips
Ventilation deserves a special mention. In a hot climate, an attic that can't breathe cooks the roof from underneath and can shorten shingle life. Good intake and exhaust vents keep the attic closer to outdoor temperature and help moisture escape.
If your home has no attic access, or the access is blocked, let the inspector know ahead of time so they can plan around it.
Flashing, vents and the small parts that leak most
Most leaks don't come from the middle of a roof. They come from the places where the roof meets something else. That's why a good inspection spends real time on:
- Flashing at walls, chimneys, skylights and valleys
- Pipe boots around plumbing vents, which crack and shrink in strong sun
- Roof vents and fans, including their seals and fasteners
- Drip edge and rake edges, where wind likes to get under the roofing
- Solar panel mounts, if you have panels, since every mount is a hole in the roof
These parts are inexpensive compared to the roof around them, and many can be repaired on their own. Finding a failed boot or a loose piece of flashing early is one of the easiest ways to avoid a bigger bill later. Our roof repair page covers the kinds of fixes that usually follow.
What you should get back: photos and plain answers
You shouldn't have to take anyone's word for what's on your roof. A useful inspection ends with photos of what the inspector found and an explanation you can follow, even if you've never been up there yourself.
Ask for these three things:
- Photos of problem areas, with enough context to see where they are on the house.
- A plain summary of the roof's overall condition and roughly how much life it has left.
- Clear options: what needs attention now, what can wait, and whether repair or replacement makes more sense.
If an inspector finds a problem but can't show it to you, ask why. And if every inspection seems to end with "you need a whole new roof," get a second opinion. Our guide to repair or replace walks through how to weigh the options honestly.
When to schedule a roof inspection
There's no single right schedule, but these are the moments when an inspection pays for itself:
- Buying a home. A general home inspection may only look at the roof from the ground. A roofer's inspection gives you a clearer idea of condition and remaining life before you close.
- Selling a home. Knowing about problems before a buyer's inspector finds them gives you time to fix them on your terms.
- After a windstorm. The Victor Valley regularly sees wind advisories with strong gusts. If shingles are in the yard, get the roof looked at. Our post on High Desert wind damage covers what to look for.
- After heavy rain or monsoon storms, especially if you notice a stain or a musty smell.
- When your insurance company asks about roof condition. Photos and a written summary give you something concrete to share.
- Every few years as a roof ages, and more often once a shingle roof is past its midpoint.
If you're not sure whether what you're seeing is serious, our list of signs you need a new roof is a good place to start.

Common questions
How long does a roof inspection take?
Most residential roof inspections take somewhere around an hour, depending on the size of the home, the roof material and whether there's attic access. Tile roofs and steep roofs can take longer because the inspector has to move carefully. Ask when you schedule so you can plan your day.
Can a roofer inspect a roof without walking on it?
Yes, to a point. Inspectors can check a lot from the ground, a ladder and the attic, and that's sometimes the safer choice on steep, wet or fragile roofs. Walking the roof usually gives a closer look at shingles, flashing and soft spots, so ask the inspector how they plan to check yours.
Should I get a roof inspection before buying a house?
It's a good idea, especially if the roof is older or you see signs of past repairs. A general home inspection may only look at the roof from a distance, while a roofer can give you a clearer read on condition and remaining life. That information can help you plan, or negotiate, before you close.
