What Sits Over the Attic: For Homeowners
Rows of clay or concrete pieces carry the bulk of the rain down to the gutters, but the watertight work is done by an underlayment on the deck below. In a driving storm, some moisture always blows in beneath the courses, and the layer beneath steers that seepage down to the lower edge.
Damage to a single tile is not usually a leak on its own, because the underlayment underneath has not been disturbed. Water that finds a hole in the underlayment may travel down the boards for some distance, and the damp patch may form far from where it entered.
Picking a Material: Points of Contrast
Fired clay comes out of the kiln dense and hard, and nothing on the face can peel off. Long exposure to sunlight does almost nothing to the way such a roof looks, while quality material turns away nearly all the rain that lands.
Concrete pieces are sand, cement and water pressed in a mold and cured, but the pigment on many lines stops just under the face. Constant sun slowly bleaches the brightest side, and a new nick exposes gray under the weathered skin. Swapping in one unit leaves an obvious bright patch, and only seasons outdoors soften the mismatch.
A concrete piece soaks up more rain than a well-fired clay one, and at the colder end of our territory, moisture held inside can freeze and expand. Cycle after cycle, the face can start to flake, and makers publish a rating for resistance to that kind of wear.
Common Shapes – Style Meets Function
A barrel roof is built from half-round pans laid face up, with covers over the gaps between them, and the design comes from centuries of Mediterranean building. An S-shaped tile folds the dip and the crown into a single unit, and many recent houses wear this version.
The flat kind sits nearly level on the deck and resembles slate or thick shake, while water steps down from course to course. Rounded designs hold on to needles, twigs and leaves, but a smoother surface gives a breeze the chance to blow debris off.
Weight and Structure: Conversions and Options
Per square foot, standard tile carries several times the pounds of shingles, and a house built under tile had its rafters sized for that from the start. Trading a light covering for a heavy one puts new demands on an older house, and a frame pushed past its limit can deflect and dip.
Ahead of a conversion, a structural engineer checks the rafters, the spans and the walls they bear on, and a few homes call for stiffening before the new covering is laid. Reduced-weight concrete exists as well, and a house that could not hold full-thickness pieces may still manage that option.
Keeping Tile in Position – Code and Exposure
A piece can be nailed or screwed through a hole near its head, and plenty of installations hook the courses over wood strips set across the slope. Elsewhere a two-part foam bonds each tile to the underlayment, while other homes have their whole field bedded in mortar. Wire ties or storm clips give extra hold on particular installations, and the approved combination comes from the maker and the local code.
Uplift is strongest around the borders of each slope, and the fastening schedule tightens at the perimeter. At the coastal end of our territory, hurricane codes set tougher requirements for keeping tile down, and installers use tested layouts for foam and screws. Mending a roof means matching the method that keeps its neighbors in place, since forcing loose a glued unit tends to break the ones next to it.
The Underlayment – Gaps in the Covering
Old roofs mostly carry asphalt felt, frequently doubled, but modern jobs often get a synthetic or a self-adhered bitumen roll. Heat gathers in the space under clay or concrete and ages whatever is beneath, so an unsuitable sheet loses its flexibility years early.
The units overhead keep daylight off the material under them, so any gap exposes a strip to rapid decay. An unstained ceiling is a poor guide to whether a missing piece can wait, because rain soon finds its way into the deck.
A New Sheet Under Old Tile: Step by Step
A major job on clay or concrete can keep the original pieces, removed by hand and stacked in the yard, and weak spots in the sheathing are repaired. A new underlayment is laid across the whole area next, and the salvaged tile goes back on top. Passers-by see the familiar face the house has always had, and the watertight layer underneath begins a second service life.
A portion of the tile breaks on the way down or back up, and the rate climbs with the age of the roof. New tile needs the same curve as the old to lap properly, and a line still in production supplies an identical match. A retired shape is covered with salvaged stock or a close equivalent, and weathered and new pieces rarely look the same at first.
Chipped Pieces: Reducing the Risk
A good many fractured tiles were stepped on by somebody, and the walker is frequently a painter, a sweep or a satellite installer. A ladder resting on the eave line breaks pieces at the bottom, and a bracket against the wall spares the covering.
A heavy bough dropping onto the slope ruins many tiles at once, and cutting back overhanging growth heads off most of that harm. At the colder end of our territory, large hail can crack a tile outright, but small stones rarely scar the face.
Tile Underfoot: For Other Trades
Where a unit sits on the course beneath, it can take a person's weight, but the unbacked middle snaps under a work boot. A rolled covering is crossed by stepping in the pans, not on the crowns, and a path used over and over gets boards so the load is shared.
Damage done by a heel commonly sits on the hidden face, and problems add up quietly from one visit to the next. A company putting panels on this material ought to involve a roofer early, so brackets land on the deck with the covering reset around them.
Valley Details: Width and Upkeep
The inside corner where slopes meet collects the runoff of both, and under tile it carries a broad pan of sheet metal. How far back the pieces are trimmed sets the open width, and a gap left too slim overflows in a heavy downpour.
Small leftover pieces along the metal have nothing to nail through, so they are held with foam, clips or wire. Litter that piles up in the valley dams the flow, and the water then works sideways beneath the pieces.
The Capping: Weather and Wear
Each outside joint, at the peak or down a corner, gets a run of rounded trim, and mortar holds it on many roofs. Heat and cold crack bedding of that kind as it ages, so the pieces loosen and crumbs wash down the slope.
Many newer roofs mechanically fasten the trim to a raised support rail, and a formed closure under it keeps weather out. Vented types let warm air out along the top, while baffles inside turn back rain and insects.
Dormers and Chimneys – Common Faults
Where a slope meets something vertical, sheet metal is bent up against the upright face, and an overlapping counterflashing keeps weather from getting behind its upper edge. A tile roof needs a broad pan there, finished with a raised rim, and the tile is trimmed so nothing blocks the flow.
A smear of roof cement along a chimney hardens and splits, and water finds that gap once more. A durable repair removes the pieces nearby and reshapes or replaces the metal, while the underlayment there is redone before the covering goes back.
Pipes and Other Openings: Details That Differ
A drain line through the deck is wrapped by a base flashing joined to the underlayment, with a lead jack beaten to the shape of the tile on top. The flat rubber boot sold for shingles will not lie tight on a barrel or S profile, so runoff slips in beneath it.
Every skylight, vent and panel mount requires flashing suited to the tile, and anything drilled through a piece without it becomes a leak.
Along the Eave – Keeping the Line Straight
Where a rolled covering stops at the gutter, every piece ends over an open arch, and birds and wasps move in and blown rain enters unless the space is blocked. A closure made for the purpose is installed along the fascia, and slots in it let moisture out.
Eave pieces have nothing below them to angle them up, so a riser brings them up to match. A sagging front row traps water on its faces, and a crooked lower line can be seen from the street.
Heat Control – When Debris Interferes
On battens or through their own curve, many coverings sit up off the wood, and air circulates in the opening left below. The current draws off heat that would otherwise pass inward, so the underlayment stays cooler.
Through a hot season, the air conditioner has less to do, while the weight of the material delays warmth reaching the living areas. An eave stuffed with debris or a ridge closed with mortar cuts off the current, so the benefit disappears.
Caring for the Surface – Pressure Washers
Newer concrete sometimes shows a powdery white film called efflorescence, and rainfall clears most of it eventually. A mat of moss or lichen keeps the joints between pieces wet, and at the colder end of our territory a hard freeze can chip the face.
High-pressure spray erodes concrete and scours glazed clay, and the stream drives water under the courses. A suitable cleaner applied with a garden-hose rinse loosens growth, and clearing valleys and gutters by hand keeps water moving.
Signs Inside and Out – Easy to Spot
- One unit sits lower than its neighbors, so whatever held it has let go.
- An empty space interrupts the pattern of tile, and the sheet beneath now sits open to sun and rain.
- Shattered tile is found on the patio after wind, though the damaged spot may sit on a slope hidden from the yard.
- Gray grit and mortar chips wash out of the downspouts, which suggests the bedding at the top is deteriorating.
- A yellowed mark grows across a ceiling, even though the way in may be some distance off.
- An inside wall near where the roof meets it turns blotchy, which suggests trouble with the flashing there.
- Thick moss or lichen covers large parts of a slope, so water lingers where it should run off.
- Part of the bottom row droops below the rest, and the board under the last course may have softened.
APC Roofing and Clay Tile Roofing in Denver Colorado: Findings You Can Use
The opening step is walking every slope, and the material, the shape and the way the pieces are set are identified. Along the way, the valleys, ridge, walls and eave are gone over in turn, and a handful of pieces are raised where the sheet below is in doubt. Up in the attic, stains and softened sheathing are looked for, as discolored wood traces where water traveled.
What turns up is photographed, with measurements taken of the extent. What was seen is set out in a written report, and each recommendation states why it is made. Where the sheet under the pieces is sound and only pieces are broken, the answer is a repair, and a worn-out underlayment is flagged plainly. The owner has the final word, and deferring the work is a valid choice.

Patch or Relay – Reading the Condition
Many faults on tile remain in one place, such as a broken piece, a rocking cap or a split flashing, so the surrounding covering is left as it is. What decides between that and a relay is the state of the underlayment, and faded or chipped faces do not settle the matter.
A slope whose sheet has given out throughout is taken up and put back over new underlayment, while the sound slopes are not disturbed. Underlayment installed in a single job generally gives out at about the same point, and the parts spared may follow within a few seasons.
Tile Over the Years – Product and Workmanship
Dense, well-fired clay can see several generations, while concrete serves for decades, if somewhat fewer. The waterproofing below is replaced well before the pieces, so its condition generally decides when work is needed.
A covering that is inspected now and then and kept free of litter tends to go the distance, while an open gap left alone can ruin the sheet early. Any figure for years is an estimate, not a promise, as grade, hold-down and flashing detail all change it.
Slope, Deck and Drainage – Sound Boards
Tile sheds rain through overlapping courses, not sealed joints, and the roof needs a steep enough angle to clear water. Shallower pitches get a sturdier underlayment, and below the minimum a different covering is the right choice.
The deck beneath has to be sound, so damaged sheets are swapped out while everything is exposed. Gutters belong to the drainage of the house, since a blocked stretch pushes water back beneath the bottom course.
