Sizing a Dumpster for a Roof Tear-Off in Largo

Roofing is where sizing goes wrong most often, and around here it is nearly always the same mistake: treating a tile roof like a shingle roof.

The one number that matters: squares

Roofers measure in squares. One square is 100 square feet of roof surface. A typical Largo single-family runs somewhere between 18 and 30 squares — the ranch and split-level housing across this county tends to be single-storey with a broad footprint, so roof areas are larger relative to floor area than in a two-storey market.

If you do not know your square count, your roofer does, and it is the first thing to ask.

What a square of roofing weighs

Run the arithmetic on a shingle roof. A 26 square architectural shingle roof at 350 lb per square is roughly 9,100 pounds — over four and a half tons before underlayment. That is a 20 yard with very little headroom, and none at all if decking is coming off too.

Shingle sizing table

Read that alongside the placement section below. On a narrow island lot the honest answer is often a 15 yard with a planned swap even where the table says 20, because the 20 will not fit.

Tile is a completely different calculation

This is the section that matters most in this county, and it is where the expensive mistakes happen.

Concrete and clay tile run 800 to 1,200 pounds per square — three to five times asphalt shingle. A 25 square tile roof can be twelve tons or more, far past what any single container can legally carry.

Two further points people miss. Tile breaks as it comes off, so it occupies more volume than the intact roof suggests while weighing the same. And clean tile is inert material with its own disposal route, so keeping it separate from underlayment and general debris is worth doing.

If there is tile on the roof, say so at the booking stage. We will plan the swap schedule rather than discovering it when the first container cannot be lifted.

The second layer problem

Plenty of older houses here have a second layer of shingle laid over the original, and it roughly doubles the tear-off weight.

Look at the rake edge from the ground, where a double layer often shows as a noticeably thicker band, and ask your roofer to confirm during the inspection. If it turns out on the day, call us — a swap mid-job is far cheaper than an overloaded container that cannot be hauled.

Worth knowing that Florida's rules on re-roofing over existing layers are stricter than in many states, so on most jobs here everything is coming off anyway.

Storm and insurance work

A large share of roofing in this county is insurance-driven, and that changes the logistics more than the material does.

Timing is unpredictable. The job starts when the claim settles, which may be weeks after the adjuster visited. Our part is being able to deliver at short notice when it does, and we would rather you call us the week the claim is approved than the morning the crew arrives.

Document before it goes in. Photograph the damaged material before it is thrown away. Insurers occasionally want to see it, and once it is in a container and hauled it is gone.

After a major storm, capacity tightens everywhere. Every roofer in the county is working and every hauler is busy. We are honest about lead times in those periods rather than promising the same-day service we run the rest of the year.

Wet decking is heavier. If water got in, the decking and any insulation below it weigh substantially more than dry material. Tell us and we size for weight.

Placement on island and older lots

Roofing containers need to sit close to the house, and placement varies enormously across our area.

• Largo, Seminole, Pinellas Park, the newer subdivisions. Generous driveways, straightforward placement tight to the drip line.
• The barrier islands. Narrow lots, tight streets, causeway access, limited parking. A 15 yard with swaps is often the only shape that works, and association rules may govern where it sits.
• Belleair, Safety Harbor, the older St. Petersburg neighbourhoods. Mature oak canopy is the constraint. The truck needs roughly twenty-two feet of clear overhead to raise the bed, and these streets frequently do not offer it.

Everywhere: boards go under the rails as standard, and a tear-off sheds an enormous quantity of nails. A magnet sweep of the driveway and street at the end of the job is twenty minutes well spent, and it is the single most common complaint homeowners have about roofing work.

The long roofing season

Unlike most of the country, roofing here runs essentially year-round — there is no winter shutdown and no waiting for shingles to seal.

What there is instead is a wet season, roughly June through September, when afternoon thunderstorms are close to daily. That does not stop roofing but it does compress the working day, and it means an open container of absorbent material will take on real weight most afternoons. Keep it covered.

The busiest stretch is usually the months following any significant storm, when insurance work and opportunistic replacement arrive at once. If you are a roofing contractor, a standing arrangement with a local hauler is worth a great deal in those periods. We hold capacity for contractors who work with us regularly and we are straight with them when we are stretched.
