Comparing Options for Concrete Tile Roofing for a Property in Kansas City Missouri?
APC Roofing fixes and relays barrel, S-shaped and flat profiles, down to the waterproof sheet beneath the surface.
Call us at 913-398-5020 and somebody experienced with clay and concrete will explain what is needed.
Anatomy of the Covering: The Basics
The visible pieces take the weather and send most rain toward the gutters, and the real waterproofing is an underlayment laid across the boards. Strong gusts force some moisture through the gaps between courses, so the layer beneath has to guide that seepage out at the eave edge.
A split tile is not the same thing as a leak indoors, as the sheet below is still doing its work. Rain that does get past a worn underlayment can run along the deck before it drops, and the visible mark and the way in do not always line up.
Picking a Material – Weathering Compared
A clay piece starts as earth pressed to a profile and baked, and there is no painted coat on the face to wear off. The sun can beat on a slope like this for decades with barely a visible change, while quality material turns away nearly all the rain that lands.
Concrete is pressed from sand, cement and water, then cured instead of fired, but the pigment on many lines stops just under the face. A slope that gets full sun lightens over the years, while a broken corner shows the gray inside. Any replacement dropped into an aged roof is easy to spot, and the difference narrows over many seasons.
A concrete piece soaks up more rain than a well-fired clay one, and at the colder end of our territory, soaked-up moisture turns to ice within the body. Over many seasons that cycle can spall the outer skin, so makers grade products by how well they resist that damage.
Common Shapes – Style Meets Function
Traditional barrel work alternates a trough turned up with a cap turned down, and the arrangement carries the look of old Spanish churches. Modern S tile rolls the dip and the hump together, and builders put it on many newer homes.
The flat kind sits nearly level on the deck and resembles slate or thick shake, and rain runs over the face of each course instead of along a channel. Barrel and S patterns collect pine needles and leaves in their hollows, but smoother surfaces let most of the debris blow away.
Weight Considerations: Conversions and Options
Standard tile has several times the mass of asphalt shingles, and a house that has worn tile since construction was built around it. Switching from a light covering to tile adds a burden nobody allowed for, and the ridge line can sag as the years pass.
Ahead of a conversion, a structural engineer checks the rafters, the spans and the walls they bear on, and reinforcement may follow where the structure lacks strength. Low-density concrete trims much of the heft, and a house that would struggle under the standard version may take the reduced version.
Anchoring the Roof: Wind and Repairs
A piece can be nailed or screwed through a hole near its head, and a lot of installations lay each course over a wooden batten. Elsewhere a two-part foam bonds each tile to the underlayment, while other homes have their whole field bedded in mortar. Certain systems add a clip that hooks the nose of each piece, and the manufacturer's instructions plus local code decide what is allowed.
Suction from wind is fiercest at the borders of a slope, and the fastening schedule tightens at the perimeter. Hurricane rules at the coastal end of our territory call for firmer anchoring, and the amount of foam and the number of screws are spelled out in advance. Any fix must suit the method already used around the damage, and a stuck unit ripped free can ruin the adjoining ones.
The Layer Below: Aging and Exposure
Organic or fiberglass felt soaked in asphalt has been the standard for generations, and more recent work relies on synthetics or self-sealing modified bitumen. The pocket under the covering stays warm for months and wears on the underlayment, so an unsuitable sheet loses its flexibility years early.
Tile acts as a sunshade for the layer under it, so a knocked-out tile opens a patch that degrades fast. An unstained ceiling is a poor guide to whether a missing piece can wait, since water passing a weathered membrane soaks into the plywood.
Work Below the Surface – Sequence of Work
A large project on this material often means pulling the pieces by hand and stacking them, after which rotten boards are swapped for sound ones. A new underlayment is laid across the whole area next, and the saved tile is relaid over it. From the street, the house looks exactly as it did before, but the protection underneath is at the start of its years.
Handling always breaks a few pieces, and old, brittle stock fails more often than newer stock. Any new tile has to interlock with the courses around it, and a design that is still manufactured can be matched exactly. A retired shape is covered with salvaged stock or a close equivalent, though the tone can still differ a little.
Cracked and Broken Pieces: Trees and Hail
A lot of splits in a tile roof come from someone stepping in the wrong spot, and the one responsible was often on the roof for some other job. Ladders propped against the lower edge snap the bottom row, while a stabilizer arm set against the siding keeps the weight off.
A dead branch landing on the roof shatters everything under it, so keeping trees clear of the house removes most of that risk. Hail of real size at the colder end of our territory breaks units outright, though pea-sized pellets usually do nothing.
Tile Underfoot – Planning a Path
A piece bears weight where it laps over the course below, while the center has no backing and fractures under a shoe. Where the tile is curved, the hollow pan is the place to step and the crown is not, and walk boards spread the load along a route used again and again.
A crack made by a boot often shows only on the underside, and harm accumulates over the years with no one aware. Solar crews and dish installers do well to plan their access with a roofer, so brackets land on the deck with the covering reset around them.
Valley Details: A Closer Look
An inside corner takes the drainage of the slopes beside it, and under tile it carries a broad pan of sheet metal. Where the pieces are cut back decides how wide the open strip is, and a narrow gap can overflow under the covering in a heavy storm.
The shortened pieces flanking the metal usually lack a hole, and adhesive foam, clips or wire hold them instead. Needles packed into the channel slow the water and pool it, so water finds its way sideways under the covering.
The Capping – Air and Closures
The joints at the peak and the outside corners are covered with shaped trim, and plenty of roofs carry it on mortar. As the seasons swing, aged bedding under the pieces cracks and crumbles, and pieces work loose while grit collects in the gutters.
On more recent roofs the trim is screwed to a raised board run along the joint, while a roll-out closure or foam closes the space below. Some of those materials are made to let air pass for attic ventilation, while their shape still keeps rain and insects from getting in.
Chimney and Wall Junctions – Common Faults
The inside corner at a vertical face is lined with bent sheet metal, and a counterflashing let into the masonry laps down over its top edge. Tile calls for a wide pan at the base, with a turned-up hem, and the adjoining tile ends short so rain has room to drain.
A bead of caulk along the corner shrinks and splits as it weathers, so rain returns to exactly that spot. A proper repair means lifting the pieces and redoing the flashing under them, and new underlayment goes in at the same time.
Things That Pass Through: Where Shingle Parts Fall Short
Where a drain line comes up, a primary flashing is lapped into the underlayment, and a lead or soft aluminum sleeve is dressed down over the tile to shed water. A shingle-style rubber collar has no way to seal over curved tile, and rain gets under its flange.
Every skylight, vent and panel mount requires flashing suited to the tile, and a rail foot fastened through a piece without it takes on water.
At the Bottom Edge – Setting the Angle
Barrel and S shapes leave an arched opening at the lower end of every piece, which lets in birds, wasps and wind-blown rain until something fills the hollow. A formed closure is set along the fascia, and weep holes in it still let water drain out.
Eave pieces have nothing below them to angle them up, so a riser strip props them up. A flat front row holds water instead of shedding it, and an uneven line at the bottom shows from the ground.
Staying Cooler – When Debris Interferes
Rolled shapes and batten systems keep the pieces lifted above the boards, leaving a channel where outside air can flow. Heat picked up by the pieces is swept out before it sinks through, which keeps the underlayment from baking.
Over a scorching summer, indoor comfort holds steadier, and dense clay or concrete holds warmth back for hours. Nests and litter at the lower edge, or solid mortar up top, stop the flow, and the pieces then hold heat against the deck.
Growth and Stains – Pressure Washers
Efflorescence, a pale mineral bloom, often appears on concrete in its early years, and weather tends to clear it without help. Growth in the laps traps water against the pieces, and at the colder end of our territory repeated freezing can spall the surface.
Power washing strips the finish that gives concrete its color, and it can break pieces as the operator walks the slope. A suitable cleaner applied with a garden-hose rinse loosens growth, while clearing the valleys and gutters by hand keeps drainage open.
Clues Around the House – Worth a Closer Look
- A tile has slipped and left a dark strip uncovered, which means its nail, clip or foam has failed.
- One spot has lost its covering entirely, and the exposed sheet begins to degrade in sunlight.
- Fragments land on the lawn or among the shrubs, though the damaged spot may sit on a slope hidden from the yard.
- Sandy gray crumbs build up below the ridge line, as the old bedding up top gives way.
- A water stain appears on an upstairs ceiling, while the opening that feeds it may lie higher up the slope.
- A wall next to the chimney has swollen drywall, which suggests trouble with the flashing there.
- Thick moss or lichen covers large parts of a slope, so drainage on that slope may be slowing.
- The eave line looks uneven from across the street, which can mean a missing riser or soft wood behind the fascia.
How APC Roofing Works on Concrete Tile Roofing in Kansas City Missouri: Findings You Can Use
The opening step is walking every slope, while the material, the profile and the way the pieces are held are noted. Along the way, the valleys, ridge, walls and eave are gone over in turn, and pieces are lifted in places where the underlayment has to be seen. The attic is checked from inside for water marks and weak boards, since the wood underneath keeps a record of old leaks.
What turns up is photographed, with measurements taken of the extent. What was seen is set out in a written report, and the reasoning behind each suggestion is spelled out. Where the sheet under the pieces is sound and only pieces are broken, the answer is a repair, and an underlayment that has failed is named as such. Choosing a path is left to the owner, with waiting one of the options.

Mending or Relaying – Sound Slopes and Failed Ones
Plenty of trouble sits in one place, be it a cracked piece, a loose cap or a wall joint, and the surrounding courses stay untouched. Choosing a small job or a relay comes down to the underlayment, and a worn-looking surface proves nothing either way.
A slope whose sheet has given out throughout is taken up and put back over new underlayment, while the sound slopes are not disturbed. Where the whole roof got its underlayment together, it ages at a similar pace, so the rest can be close behind.
How Tile Ages – What Shortens the Span
Quality fired clay can keep going for a century or more, and concrete holds up for many decades, as a rule not quite as long. The waterproofing below is replaced well before the pieces, so its condition generally decides when work is needed.
A roof checked regularly and kept clear of debris gets its full span, while an open gap left alone can ruin the sheet early. Every service figure is an approximation, not a commitment, and the grade of the product, the fastening and the flashing work all move it.
Pitch and Decking – Sound Boards
Each course of tile overlaps the next instead of being sealed to it, so there must be enough incline for rain to drain quickly. Where the pitch is modest, a stronger underlayment system is required, and under the permitted limit another covering does the job better.
Every board under the tile needs to be firm, and rotten or delaminated wood is replaced while the roof is open. Gutters are part of how the roof drains, because an overflowing trough can send water under the eave pieces.
