Clay Tile and Asphalt Shingle Are Not the Same Job

A tile roof and a shingle roof of identical size produce loads that differ enormously in weight. Picking by roof area alone is how people end up with a box that cannot be lifted.

⭐ Why roof type decides everything

Roofing is the one job where sizing by area actively misleads, and Santa Ana makes it worse than most places because both major roof types are common here in quantity.

Roofers measure in squares — one square is a hundred square feet of roof surface. That is the unit worth using, because weight per square is where the two diverge completely.

The split follows the architecture. The Spanish Colonial Revival stock across Wilshire Square and the historic districts is heavily tiled. The post-war tracts in Sandpointe, Santa Anita, Madison Park and Cornerstone Village are predominantly shingle, with tile on some later rebuilds.

Clay and concrete tile: heavy, and heavier than you think

Tile is by a wide margin the heaviest roofing material you will deal with, and a square of it weighs several times what a square of asphalt shingle weighs.

On a typical single-story Santa Ana home that turns a tear-off into a genuinely heavy load, and the arithmetic goes the same way it does with concrete: the container reaches the weight a truck can legally lift long before it looks full.

⚠️ So a tile tear-off is a 10 yard container, part-filled, and on anything but a small roof it is more than one of them. A customer who orders a 30 yard because “it is a big roof” has ordered a box that cannot be collected once it is a third full — and the 30 costs more than the two 10s that would actually have worked.

Two things help on a tile job. Tile being salvaged for reuse should come off and be stacked separately before anything goes in the container — it has real value, it is the heaviest thing on the roof, and on a permitted job salvage counts toward your diversion. And the underlayment, battens and fixings are a separate, much lighter stream.

Asphalt shingle: the familiar case

Asphalt shingle is what most roofing advice is written about, and here the standard guidance roughly applies.

A square of asphalt shingle runs a few hundred pounds, more with heavier architectural shingle. An average Santa Ana home's shingle tear-off is a 20 yard container, and that is a comfortable fit rather than a tight one.

Shingle loads are also the easiest to keep clean, which is worth doing. A tear-off that is nothing but shingle and felt is a simpler and cheaper disposal than the same load with the gutters, the fascia and the packaging mixed in.

⚠️ Layers, and the question to ask your roofer

A roof that has been shingled over rather than stripped carries double the material, and that genuinely changes the container.

So the single most useful question before you book is: how many squares, and how many layers? Your roofer will know both, because it is how the job was quoted.

Two layers of shingle on an average home is the difference between one 20 yard and two, or between a 20 and a 30. Finding that out on the phone costs nothing; finding it out when the container is full costs a second haul.

⭐ The things that are not roofing but end up in the load

Most roof jobs are not purely roof, and the extras are where clean loads go wrong.

Old swamp coolers. Common on older Santa Ana roofs and they come off during a reroof. The shell is scrap metal and belongs in a scrap pile, not the container.

Air conditioning units. ⚠️ If a refrigerant-bearing unit is coming off the roof, the refrigerant must be recovered by someone qualified before the shell is scrapped.

Gutters, flashing and fascia. Metal, and worth pulling out as scrap rather than burying — it is fully recoverable and it is heavy.

Skylights. Glass and framing.

Packaging. A surprising volume on a full reroof — wrapping, banding, pallets.

Old solar mounts and hardware. Increasingly common.

On a permitted reroof all of this matters twice over, because pulling the metal out improves both your load weight and your CALGreen diversion figure.

Sizing by squares, properly

Get the square count and the layer count from your roofer, then apply the material.

Asphalt shingle, single layer: a 20 yard covers an average home here.

Asphalt shingle, two layers: a 30, or two 20s.

Clay or concrete tile: a 10 yard, part-filled, and plan for more than one on anything but a small roof. Do not be talked into a bigger box.

A mixed reroof — tile off, shingle on, or any combination — is two streams of very different density and usually two containers.

⚠️ Placement for a roof job

A roofing container wants to be as close to the work as possible, because every yard of carrying distance is multiplied by several tons of material.

Think about which elevation the tear-off comes off first and put the box there. Leave room for the crew to work around it. And clear anything overhead — in the historic districts the mature canopy over the driveway decides the placement whether you like it or not.

On a tile job the load is heavy, so the approach needs to be firm and straight. A loaded tile container on an older, thinner pre-war driveway is the one combination genuinely worth planning for in advance, and we will bring extra timber for it.

Keeping a tear-off load clean

The cleanest arrangement on a roof job is simple: roofing material in the container, metal in a separate pile for scrap, and anything with refrigerant handled properly before it goes anywhere.

That gives you a lighter container, a cheaper disposal, a better diversion figure if the job is permitted, and a scrap pile that is worth something. It costs nothing except deciding to do it before the first bundle comes down.
