If you own a home in Tucson, there is a good chance you have concrete tile on your roof, and a tile roof inspection is the only reliable way to know what shape it is in. Tile is the right material for this climate. It shrugs off UV, it does not curl in 105 degree heat, and the tiles themselves can last 50 years or more.

That longevity is also why tile roofs get ignored. The roof looks fine from the driveway, so nobody thinks about it until there is a stain on a bedroom ceiling. A tile roof inspection is how you catch problems while they are still a few hundred dollars instead of a few thousand.

Here is exactly what a licensed roofer checks when we get on your roof, why each item matters in Tucson specifically, and what your inspection report should include when we are done.

Your tile is not what keeps the water out

This is the most misunderstood thing about tile roofs, and it changes how you should read every item below. The tile is a sunshade and a first line of defense. The actual waterproofing is the underlayment, the layer of felt or synthetic membrane rolled out across the decking underneath.

Most underlayment installed on Tucson tile roofs is rated for roughly 20 to 25 years. The tile above it can outlive two underlayments. So when a tile roof finally fails, the tile is usually still in good shape. The layer doing the real work has dried out, gone brittle, or been ground up by a broken tile sliding on top of it.

A tile roof inspection is really an underlayment inspection with a tile inspection wrapped around it. Any roofer who never lifts a tile is not inspecting your roof.

What roofers check during a tile roof inspection

This is the checklist we work through on every tile roof, in roughly the order we walk it.

Cracked, chipped, and broken tiles

We look for cracked, chipped, and broken tiles across every slope. Damaged tile exposes the underlayment to direct sun, and UV is what kills underlayment faster than anything else in southern Arizona. Broken pieces also slide and abrade the membrane below. Replacing a handful of tiles is inexpensive. Replacing the underlayment they exposed is not.

Tile alignment and slipped tiles

Tiles should sit in straight, evenly spaced courses. We check for tiles that have shifted, lifted, or slipped out of position, especially along hips and ridges where tiles are often set in mortar rather than fastened. Monsoon wind and foot traffic both move tile. A shifted tile leaves a gap that drives rain straight onto the underlayment.

Valleys, ridge caps, and weather blocks

Valleys carry the most water on the roof, so we check valley metal for corrosion, debris buildup, and tiles cut too close to the channel. At ridges and hips we look for missing weather blocks, the molded plastic or mortar pieces installed under the tile that stop wind driven rain from pushing up and under. Skipped weather blocks are one of the most common shortcuts we find on Tucson roofs, and they are a frequent source of leaks that homeowners cannot trace.

Mortar packs at hips and ridges

Where tile runs end at hips and ridges, the ends are usually sealed with mortar. Those mortar packs keep water out and help hold the tile in place. Arizona sun and thermal cycling crack them over time. Cracked or missing mortar is normal maintenance on a roof past ten years, and it is cheap to repair when we catch it early.

Flashing at walls, chimneys, and skylights

Most leaks start at a transition, not out in the open field of the roof. We inspect flashing at chimneys, sidewalls, headwalls, skylights, and every other penetration for correct installation, corrosion, failed sealant, and separation. Sealant is not a substitute for properly installed flashing, and a bead of caulk over a flashing gap is a repair with a two year shelf life at best.

Underlayment and roof decking

This is the part of the inspection that determines whether you need a repair or a full underlayment replacement. We lift tile in representative areas to see the condition of the membrane: brittleness, cracking, tearing at fasteners, separation at laps, and any staining that points to water already getting through. Where the attic is accessible, we check the decking from underneath for moisture marks and rot.

Roof penetrations

Plumbing vents, exhaust vents, satellite mounts, solar standoffs, and anything else that punches through the roof gets checked individually. Vent boots dry out and split. Satellite and solar mounts installed by someone other than a roofer are a recurring problem, because they are often fastened through tile with no flashing at all.

Eaves, soffits, and fascia

Damage at the eaves is often the first visible evidence of a problem higher up. We look for water staining, soft wood, peeling paint, and rot along fascia and soffits. If there is rot under the eave, something above it has been leaking for a while.

Previous repairs

Old repairs are easy to spot because replacement tiles have not faded to match the originals. We check how those repairs were done, since a bad previous repair frequently causes the next leak. Sealant slopped across tile, the wrong mortar, mismatched profiles, and fasteners driven through tile faces all tell us something about how the roof has been maintained.

How often should you schedule a tile roof inspection?

You do not need somebody on your roof every quarter. These are the points where an inspection genuinely earns its keep:

• Once a year, ideally in late spring. You want problems found and fixed before the first monsoon cell, not after.
• After any major storm. High wind shifts tile and cracks ridge caps without leaving a single sign visible from the ground. Our guide to monsoon tile roof damage covers what to look for.
• Before you buy a house. A standard home inspection glances at the roof from a ladder. It does not lift tile, and it will not tell you whether the underlayment has two years left or twenty.
• Every couple of years once the roof passes 15. That is when underlayment starts approaching the end of its service life and you want to plan for the expense rather than be surprised by it.

What a good inspection report looks like

A tile roof inspection is only useful if you can see what the roofer saw. Every report should include dated photos of each finding, a plain explanation of what the photo shows, and recommendations sorted by urgency: what needs doing now, what can wait a season, and what does not need doing at all.

Be cautious with any company that gives you very little information and a large proposal. If a roofer cannot show you a photo of the problem and explain it in terms you understand, that is a reason to get a second opinion, not a reason to sign. Your roof is the most expensive protective system on your house, and you are entitled to enough information to make your own decision.

Tile roof inspection FAQs

How much does a tile roof inspection cost in Tucson?

Our standard tile roof inspection is free, including the climb, photo documentation, and a written findings report. The only inspection we charge for is a formal sealed report when a lender or a real estate transaction specifically requires one.

How long does a tile roof inspection take?

Most residential tile roofs take about 45 minutes to an hour on the roof, plus attic access where it is available. Larger or more complex roofs take longer. You get the report the same day or the next day.

Can I inspect my own tile roof?

We do not recommend walking a tile roof. Tile breaks under foot if you do not know where to step, so you can easily create the damage you were looking for. Checking your ceilings, eaves, and gutters from the ground is useful. Leave the roof itself to a licensed roofer.

Does a cracked tile mean I need a new roof?

Usually not. Individual tiles are replaceable, and matching tile color is the harder part of that job. What determines repair versus replacement is the condition of the underlayment beneath, which is why lifting tile during the inspection matters so much.

How long does a tile roof last in Tucson?

The tile itself commonly lasts 50 years or more. The underlayment underneath is the limiting factor, and most of it needs replacement somewhere around the 20 to 25 year mark. Regular inspections are what tell you where you are on that curve.
