Most of a sewer line is buried, and it does its job quietly until it does not. A sewer scope is the way to look inside it. It is an add-on to a home inspection, and it is easy to skip when a closing date is close. This post explains what it is, when it makes sense, and when it does not apply.

What a sewer scope is

A sewer scope is a camera run of the main sewer line, the pipe that carries wastewater from your house out toward the connection at the street or property edge. We feed a small waterproof camera into the line through an access point, watch the live picture, and take stills of what we find. Then we write it up in plain language, with photos and a clear next step for each finding.

The camera can show cracks, breaks, roots working into joints, pipe that has sagged so water pools in it, pipe that has come apart at a joint, and heavy buildup. It gives you a look at a part of the house that a normal inspection cannot see, because the pipe is underground.

Here are the times we most often suggest a scope.

You are buying an older home

Older Tucson neighborhoods can have clay or cast-iron sewer pipe. Those materials can crack, shift at joints, and let roots in over the years. A house can look great and still have a pipe problem underneath the yard. If the home was built long ago and nobody can tell you the age or type of the line, a scope replaces guessing with a picture.

There are signs of trouble

Slow drains in more than one fixture, gurgling sounds, backups, sewage smells outside, or a patch of lawn that stays wet or green for no reason can all point at the line. If you own the house and any of these sound familiar, a scope can tell you whether the pipe is the cause before you pay a plumber to guess.

Large trees are near the line

Roots look for water, and a sewer joint is a small source of it. Mature trees close to the house, the yard, or the path of the line are a good reason to look. A scope shows whether roots have found a way in, and how much.

You are selling

Sellers sometimes scope the line before listing so there are no surprises during the buyer’s inspection period. If a problem turns up, you can plan the repair on your schedule and talk about it openly instead of negotiating in a hurry. It pairs well with a seller home inspection, which covers the rest of the house.

You are buying a home that sat vacant

Pipes that go unused for a long time can build up debris, and a house that sat empty may have had problems nobody noticed. A camera run is a reasonable way to check before you move in.

You plan to remodel or dig

Before a pool, an addition, new landscaping, or heavy equipment goes near the line, it helps to know what shape the pipe is in.

When a sewer scope does not apply

A scope covers the main sewer line. If the home is on a septic system rather than a connection to a sewer, there is no main line to scope in the usual way. First Defense does not inspect septic systems or wells, so for those, please hire a septic or well specialist. We would rather tell you that plainly than let you assume a home inspection covers them.

A scope also cannot tell you the future. It shows the pipe on the day we run the camera. It cannot tell you exactly when a pipe will fail, and it will not show problems the camera cannot reach, such as a section blocked so completely that the camera cannot pass. If that happens, we will say so in the report and explain what the next step might be.

What happens if the scope finds something

Not every finding means a big repair. Here is how we usually explain the possible results:

• A clear line with normal wear: nothing to do, and you have a record of the pipe’s condition
• Minor roots or buildup: often handled by cleaning, with a plan to check again later
• Cracks, offsets, or a sag: a plumber or sewer contractor should evaluate, and you may want to ask the seller to address it or adjust the deal
• A collapsed or badly broken section: get a repair estimate before you close, if you are buying

Our report does not set the repair terms. It gives you photos and information so you, your agent, and a licensed plumber or sewer contractor can decide what happens next.

How to add it to your inspection

If you are buying, ask for the scope when you schedule the home inspection so it can happen within the same inspection period. Tell us the address and whether you know where the cleanout is. Our sewer scope inspection page has more on how the process works. We serve Tucson, Oro Valley, Marana, Sahuarita, Green Valley, and Vail.

If you own the home and just want to know what is going on underground, we can run the camera on its own.

Monsoon storms in Tucson arrive fast and hard. Wind pushes rain sideways, water sheds off the roof all at once, and a weak spot that stayed dry for months can suddenly show itself. A careful look after each storm helps you catch small problems before the next one turns them into ceiling stains.

First Defense Building Inspection is owned by Kief Manning, a disaster relief inspector who holds Arizona Board of Technical Registration license #76157. This is the checklist we would hand a neighbor. It sticks to what you can see safely from the ground and from inside the house.

Safety comes first

Please do not walk on a tile roof. Tiles crack under a person’s weight, and a cracked tile you cannot see becomes a leak you will find later. Tile is also slick, hot in the afternoon, and easy to slide off. Foam and shingle roofs can be slippery when wet, and foot traffic can damage a foam coating.

Wait until the roof is dry and the lightning has moved on. Stay well away from downed power lines or anything hanging from the roof. Use binoculars or the zoom on your phone instead of a ladder. If you need to be up there, hire a professional who does this every day.

Walk the outside of the house

A slow lap around the property the morning after a storm tells you a lot. Look for these things:

• Pieces of tile, shingle, or foam coating on the ground or in the yard
• Fresh streaks or dark stains on stucco under the roof edge
• Gutters that have pulled away or hold standing water
• Soil washed out near downspouts, or puddles sitting against the foundation
• Debris such as branches, palm fronds, or loose items that landed on the roof

Tile roofs

From the ground, look for cracked, slipped, or missing tiles. Rows should look straight and even. A tile that sits crooked or sticks up can let water in underneath. Check the ridge and hip caps too, the tiles that cover the peaks, because the mortar or fasteners there can crack and open a path for rain.

Remember that the tile is only the outer layer. The material underneath does a lot of the waterproofing, and you cannot see its condition from the ground. That is one reason a roof that looks fine can still leak, and why an inspector looks closely at older tile roofs.

Shingle roofs

Look for missing, lifted, or curled shingles and for any that look creased across the middle, which is a common sign of wind. Bare patches, exposed nail heads, and dark streaks are worth a photo. Check your gutters and downspout outlets for a gritty layer of granules. A little is normal on an aging roof, but a heavy pile after one storm suggests the surface is wearing out.

Foam roofs

Foam roofs are common in our area, and the coating on the surface is what protects the foam from sun and water. After a storm, look for:

• Water still standing on the roof long after the rain stopped
• Blisters, bubbles, or soft-looking spots
• Cracks or splits in the coating
• Worn, chalky, or peeling areas where the foam may be showing

Exposed foam breaks down in the sun, so do not put off a coating repair. A roofer who works with foam can tell you what it needs.

Flashing and roof penetrations

Flashing is the thin metal or sealed material where the roof meets something else. It is where many monsoon leaks start. Look at the areas around chimneys, skylights, vent pipes, cooling units, walls that rise above the roof, and the places where two roof slopes meet. Warning signs include:

• Metal that has lifted, bent, or rusted
• Gaps or cracked sealant along the edges
• Rust or water trails running down the wall below

If your home has parapet walls, look at the upper edge and the joint where the wall meets the roof. Water finds the smallest gap there.

Drains, scuppers, and gutters

Flat and low-slope roofs move water to drains and scuppers, the openings in the parapet that let water out. If they clog with leaves, dirt, or granules, water backs up and sits on the roof. Look at each opening from a safe spot and clear anything reachable from the ground. Make sure downspouts carry water well away from the house, not straight onto the slab. Extensions and splash blocks help. Grading that slopes toward the house should be fixed before the next storm.

Check the attic and ceilings

Some of the clearest clues are inside. After a storm, walk through the house and look at ceilings and the upper parts of walls for new stains, bubbling paint, or drips. Then open the attic hatch and shine a flashlight around from the opening. You are looking for:

• Dark or brown stains on the underside of the roof deck
• Damp or matted insulation
• Daylight coming through where it should not
• A musty smell

Stay at the hatch unless you know where it is safe to step, because you can put a foot through a ceiling. If a stain looks new, circle it with a pencil, write the date, and take a photo. Check it again after the next storm. A stain that grows means water is still getting in. If you also notice a musty smell or damp materials, a mold inspection can look at the moisture source and what it may have affected.

What to do with what you find

Take clear photos with the date, and keep them in one folder. For an active leak, call a roofer right away and ask about temporary protection. For anything you are unsure about, or if you are buying a home and want to know how the roof has held up, a home inspection in Tucson includes a careful look at the roof surface, flashing, drainage, and attic. We serve Tucson, Oro Valley, Marana, Sahuarita, Green Valley, and Vail.

A good habit is one lap around the house after every big storm. It takes ten minutes, and it beats finding out about a leak from a wet ceiling.
