Tile Roof Installation Cost Calculator

Most tile roofs run $10 to $25 per square foot installed, so an average 2,000 sq ft roof lands somewhere between $20,000 and $50,000. Concrete tile is the most economical (around $12/sq ft installed), synthetic/composite sits in the middle (around $14), and clay is the premium option (around $16 and up). On top of the tile itself, tear-off of the old roof, roof complexity, structural work, and a premium underlayment all move the number. It's one of the pricier roofs upfront, but also one of the longest-lasting.

Tile is priced per square foot of actual roof surface, and a sloped roof always has more surface than the floor beneath it. A steeper pitch means more square footage over the same footprint — a 1,600 sq ft house can easily have a 2,200 sq ft roof. Roofers measure in 'squares' (100 sq ft each) and add for pitch and overhangs. If you only know your home's footprint, expect the roof area to be meaningfully larger, which is why the calculator asks for the roof surface, not the living area.

Concrete tile is molded from cement and sand — durable, widely available in many profiles and colors, and the most affordable tile, typically lasting 30 to 50+ years (though its color can fade). Clay tile is kiln-fired terracotta: the classic Spanish/Mediterranean barrel look, with color that's baked in rather than coated, and a lifespan often reaching 50 to 100 years — but it's the most expensive and heaviest. Synthetic/composite tile mimics the look of clay or slate at a fraction of the weight, which makes it useful when the roof structure can't carry heavy tile. The calculator lets you compare all three.

This is the single most important question before switching to tile. Tile weighs roughly 600 to 1,100+ pounds per square (100 sq ft), two to four times heavier than asphalt shingles. If your home was originally built for tile, the framing is already rated for it. But if you're converting from shingles, the existing rafters or trusses may not carry the load, and a structural engineer should evaluate it — reinforcement is sometimes required, which is why the calculator includes a structural-reinforcement add-on. When the structure can't be economically reinforced, lightweight synthetic tile is often the answer. Never skip this assessment.

For a re-roof, almost always yes. Tile relies on a fresh waterproof underlayment laid directly on a sound deck as its real water barrier, so the old roofing has to come off down to the sheathing — you can't lay proper underlayment over old shingles. Tearing off also lets the roofer inspect and repair the deck and confirm the structure is ready for the tile's weight. The main exception is new construction, where there's no old roof to remove. The calculator lets you include tear-off (about $2/sq ft) or skip it for new builds.

The tiles themselves are extremely long-lived — clay commonly 50 to 100 years, concrete 30 to 50+ — often outlasting the home's other components. The catch is the underlayment beneath them, which is the actual waterproofing and typically lasts only 20 to 30 years. That means at some point the tiles may be lifted, the underlayment replaced, and the good tiles reinstalled ('lift and relay') rather than a full tear-off. Budgeting a premium high-temp underlayment upfront extends that interval and is a common, worthwhile add-on on the calculator.

Beyond the tile and tear-off, the big adders are structural reinforcement (for heavy tile on an under-built roof), a premium underlayment, a batten system that the tiles hang on, ridge and hip caps set in mortar, new flashing at walls and penetrations, and a steep-slope premium when the pitch requires extra safety setup and slower work. Roof complexity multiplies labor too — every hip, valley, dormer, and penetration means more cutting and detailed flashing. The calculator breaks these out so you can see which apply to your roof rather than burying them in one number.

Plan on roughly one to two weeks for an average home — longer than asphalt because tile is heavy, detailed, and set piece by piece. The job runs through tear-off and deck repair, any structural reinforcement, underlayment and flashing, battens if used, then setting the tiles and finishing ridges and hips. Roof size, complexity, steep pitches, and weather all stretch the timeline, and specialty clay or custom-color tile can add weeks of lead time to order before work even starts. A skilled tile crew is essential and there are fewer of them, so scheduling can also affect your start date.
