Tile Roofing

What a Tile Roof Repair Actually Involves

A tile rooftop is a layered system. The tile is the shield; the underlayment beneath it is the waterproofing. When water seeps past a cracked field tile, it wicks along the roof deck until it finds a nail hole or a gap.

A repair is not a patch on top. It is a rebuild of the layers below the broken tile, in the same order they went on the first time.

1. A roof inspection comes first, on the rooftop and in the attic, where we check pitch, flashing condition, decking, and moisture content before quoting anything.
2. Crews lift broken tile with a pry bar and roofing shovel, stack reusable pieces, and send debris down to a dumpster so the ladder and scaffold stay clear.
3. We cut out failed roofing felt and tar paper, then roll new synthetic underlayment across the substrate to separate water from the sheathing.
4. A self-adhered ice-and-water shield goes along eaves and valleys, where an ice dam or wind-driven rain would otherwise back up under the tile.
5. New battens and counterbattens fasten to the purlins with ring-shank nails and screws, so the field course has something solid to lock onto.
6. Reset tile goes back in staggered courses, and we hand-seal hips, ridges, and the verge with mastic and roof cement.
7. Drip edge protects the eave and rake, a ridge cap and ridge vent close the peak, and step flashing plus counter-flashing get rebuilt wherever the roof meets a wall.

Clay, Concrete, and the Materials We Work With

Tile covers a lot of ground in the Valley, and the system around it matters more than the tile itself. Here is what we install and repair most often, and why roofers in this climate choose what they choose.

• Clay tile and concrete tile are the two heaviest coverings we handle, and both shrug off UV for decades if nobody walks on them.
• A slate roof, or wood shake and cedar shake on an older home, needs lighter foot traffic and different fasteners than tile.
• Architectural shingle, three-tab shingle, and asphalt shingle weigh far less, which suits homes that were never framed for tile.
• Standing-seam metal panel and corrugated panel handle low slopes and modern rooflines better than anything else we stock.
• On flat sections, TPO, EPDM, or PVC membrane replaces a built-up roof and modified bitumen surface that has blistered past repair.
• Under all of it sits bitumen, roofing felt, tar paper, or synthetic underlayment, which is the layer actually keeping water out.
• We install systems from GAF, Owens Corning, and CertainTeed, and we will tell you when a tile repair is the smarter spend than a full replacement.

What Goes Wrong Under Phoenix Sun

A tile roof fails slowly, and the first sign is usually cosmetic. By the time water stains a ceiling, the underlayment has been leaking for a while.

• Spalling, cracking, and flaking on clay tile open the laps, and water wicks down the underlayment from there.
• Granule loss on asphalt shingles signals end-of-life wear rather than dirt; once the mat oxidizes, the shingle is finished.
• Rot and decay in the fascia, soffit, and sheathing usually trace back to a clogged gutter or a downspout emptying at the foundation.
• Sag or settle in the roofline points at a rafter, truss, or ridge beam holding moisture, and a soft joist telegraphs the same way through the ceiling below.
• Ponding water behind a parapet or at a scupper means the drainage never worked, and the coping has been holding water for years.
• Delamination, blistering, and alligatoring on modified bitumen say the surface peeled past what a coating can fix.

Attics, Ventilation, and the Details That Fail First

The leak you spot on a ceiling usually starts somewhere else. Ventilation, insulation, and small penetrations are where tile roofs in Maricopa County leak first.

• Insulation and ventilation work together; without a soffit vent or attic fan, attic heat bakes the underlayment from below.
• A vapor barrier keeps condensation off the roof deck and sheathing, and trapped moisture there is what actually causes rot.
• Pipe flashing, a pipe boot, or a vent boot seals plumbing and exhaust stacks, and it is the most common leak point we find.
• Chimney flashing, apron flashing, and boot flashing need counter-flashing cut into the masonry with a bead of adhesive or sealant behind it, not smeared over with caulk.
• A skylight, dormer, canopy, or awning penetration moves water differently and needs its own flashing detail.
• Gutter and downspout runs carry monsoon water off the roof, and a coating restores color on tired tile without a tear-off.
• On a mansard or gambrel section, a scupper, parapet, and coping handle drainage where an overhang cannot reach.
• Snow guard brackets and roof anchors are rare here, but we set them for weatherproofing and safety harness tie-offs on steep pitch.

Phoenix Heat, Monsoon Hail, and Honest Timelines

Phoenix gets about 111 days a year at or above 100 F and roughly 21 days at or above 110 F. Heat does not crack tile. It dries the underlayment beneath it until the sheet turns brittle.

With about 3,872 hours of sunshine each year, UV photo-degrades shingle, coating, and underlayment from the top down. The record high here is 122 F, set on June 26, 1990, and roofs behave differently at that number.

Hail is the other risk. The 2025 monsoon dropped hail across the Valley and damaged more than 500 homes in Tempe alone. Tile takes impact better than asphalt, but hail bruises shingle and cracks the occasional field tile.

On a 1970s ranch in Coronado, we pulled three broken concrete tiles and found the original felt had turned to dust along the valley. The owner had been quoted a full replacement.

A valley rebuild and new underlayment over one slope stopped the leak for a fraction of that number. That job is why we open a roof before we price it.

• A single tile repair or flashing reset usually finishes in a day, and we can often match the color of existing clay tile.
• A partial refit over one slope takes two to four days, depending on tile count and how much decking we replace.
• A full tear-off and relay runs longer, because lifting heavy tile, swapping plywood or OSB sheathing, and reinstalling batten and tile is slow, careful work.
• Active monsoon damage gets priority, and we treat a leaking roof as an emergency roof repair whenever the schedule allows.

What It Costs and How We Estimate It

We quote from a line-item estimate, because tile work hides surprises under the first course. Here is what moves the number up or down.

• Cost drivers include tile weight, roof pitch, the count of valleys, hips, and gables, and whether building code requires a new ice-and-water shield.
• We measure in roofing squares, where one square is 100 square feet, so your roof estimate matches the material order tile for tile.
• Crews run a nail gun off an air compressor for underlayment, and a torch only where a modified bitumen detail calls for one.
• Storm damage repair is often covered by insurance, and we handle insurance claim assistance with a line-item estimate built for an adjuster inspection.
• Estimates are free, and we will tell you when a repair is the right call instead of a replacement.
