The Better Roofing Bid Explains Where the Debris Will Fall

A roof replacement does not stay on the roof. Torn shingles, nails, flashing and underlayment have to reach a trailer or dumpster at ground level. On a simple ranch with an open driveway, that route may be short and clear. On a St. Louis house with mature landscaping, a narrow side yard, close neighbors or several roof levels, debris control becomes part of the job. Two roofers can quote the same Atlas or Malarkey shingle and still propose very different plans for protecting the property below.

Roofer comparison

Ask each bidder to walk around the house with you before discussing protection. The useful question is not whether the crew will be careful. Ask where material will be dropped from each roof section and what is directly underneath that point. A roofer should be able to identify the driveway, planting beds, air conditioning equipment, decks, windows, siding, exterior lights and gates that affect the tear-off.

Most old shingles leave the roof in one of three ways. Workers may carry them to a controlled drop point, slide them down a temporary chute or throw them onto a collection surface below. Each method can work if the ground is prepared and the landing area is kept away from people and fragile property. The trouble starts when the plan is simply to cover everything with a tarp after the crew arrives.

A tarp lying directly on shrubs is not much protection from bundles of torn shingles. The weight can split branches and flatten plants. A better plan creates space between falling debris and the landscaping. That may mean rigid panels, upright supports, temporary netting or a collection system angled away from the wall. The proposal does not need to name a particular product. It should make clear which sides of the house receive protection and how that protection will be supported.

Look closely at the wall below a steep roof. Loose granules and nails can slide quickly, and old metal flashing can have sharp edges. Siding, screens and glass need more than a promise that debris will be thrown outward. Ask whether the roofer will shield lower windows and doors, and whether those doors will remain usable during the work. One safe entrance should be identified before the first bundle comes off.

Driveway protection deserves its own answer. A loaded dump trailer places concentrated weight on tires and the jack or tongue. Fresh asphalt, thin concrete and decorative paving can respond differently. Ask where the trailer will sit, whether boards or pads will distribute the load, and whether the driver needs to cross a curb, irrigation line or sidewalk. If a dumpster will remain overnight, confirm its location and the planned pickup time in writing.

The air conditioner also needs a specific plan. The outdoor unit must breathe, so it should not be wrapped tightly and left running. Ask whether the roofer expects the system to be turned off while nearby roof sections are stripped, how the unit will be shielded from falling debris, and who will remove the cover before it is restarted. A falling nail or piece of flashing can damage the coil even when the unit is several feet from the wall.

Protection should extend beyond visible objects. Ask about low voltage wires, landscape lighting, hose bibs, gas meters and electrical service equipment. Satellite equipment and roof mounted accessories should be listed in the scope if they will be removed, reset or left in place. If a cable crosses the likely debris path, the crew needs to see it before tear-off begins.

St. Louis lots often add access problems. In parts of the city and older inner suburbs, houses may sit close together with narrow passages between them. Chesterfield and Ladue properties may have long drives, extensive planting beds or multiple roof elevations. Kirkwood tree cover can limit where a trailer is placed. A proposal copied from an aerial measurement cannot settle any of those ground conditions. The bidder has to look at them.

What it costs

Property protection is usually folded into labor, setup or general job costs rather than shown as one neat line. That does not make it free. Supports, panels, tarps, magnets, additional labor and extra handling all consume time. A crew that cannot drop material directly into a trailer may need to move it across the property by hand. That difference can legitimately affect the bid.

Ask whether the quoted price includes protection for every side receiving tear-off debris. A vague allowance may cover the front beds while leaving a deck or rear patio outside the plan. Also ask whether extra labor for a long carry to the trailer is already included. If access was visible during the inspection, it should not appear as a surprise charge on installation day.

Some costs depend on choices the homeowner controls. Moving patio furniture, grills, planters and vehicles before the crew arrives reduces setup time and prevents avoidable damage. Marking sprinkler heads can keep trailer tires and foot traffic away from them. Unlocking gates and clearing pet waste gives workers a usable route around the house. The roofer should provide these instructions before the scheduled start, not while the crew is waiting.

Weather affects the protection plan too. St. Louis freeze thaw cycles can leave soft ground even when the morning surface looks firm. A trailer crossing a lawn may rut it. Spring hail season can bring a fast second storm while the old roof is open. Winter work can leave ice at an eave or on a shaded walk. Ask what ground or weather condition would cause the roofer to postpone, change the trailer location or stop tear-off.

Cleanup is related to protection, but it is not the same thing. Tarps and collection surfaces reduce the spread of debris. Magnetic sweeps help find steel nails after the roof is complete. Neither method finds every piece in mulch, tall grass or dense ground cover. A written plan should say where magnetic sweeping will occur and whether the crew will perform a final visual pass through planting beds, gutters, decks and paved areas.

Consider the cost of a second cleanup visit. Nails can settle into grass or wash out of a gutter after rain. Ask whether the roofer will return if you find a concentrated area of debris shortly after completion. Get the answer before selecting the bid. A general statement that the site will be clean does not explain how a reported problem will be addressed.

What to ask

Use the same questions with every bidder so the answers can be compared on one sheet:

• Where will shingles and metal leave each roof section?
• Which windows, doors, planting beds and hard surfaces will be shielded?
• How will protection be held above shrubs instead of resting directly on them?
• Where will the dump trailer or dumpster sit?
• Will boards or pads be placed under tires, jacks or container contact points?
• How will the air conditioner be protected without blocking it while it runs?
• Which entrance can the family use during the work?
• How will gates, pets and neighboring property be handled?
• How many magnetic sweeps are included, and where will they be performed?
• Who walks the property with the homeowner after cleanup?

Photographs make these answers more useful. Before work starts, photograph the driveway, siding, screens, decks, landscaping and outdoor equipment. The point is to establish the condition of the work area and help everyone notice vulnerable items. Ask the roofer to add photographs of any existing cracked pavement, bent screen, damaged plant or stained siding to the job file before materials arrive.

Confirm responsibility for preparation. The homeowner may be expected to move vehicles and loose objects. The roofer may be expected to install shields, establish exclusion zones and protect fixed equipment. Those duties should not be left to assumptions. If a delicate Japanese maple, glass awning or pond sits below the eave, have the proposal name it and state the agreed protection or access limitation.

Ask how the crew controls access while material is falling. Children, visitors and pets should not pass through a drop zone. Delivery drivers may still approach the house, and a neighbor may use a shared drive without knowing work has started. Cones, tape and a clearly designated entrance are simple details, but they show whether the site plan extends beyond the workers on the roof.

Also ask what happens at the end of each day. Loose wrappers and underlayment can travel quickly in a St. Louis wind. Tools, ladders and unused material should not block the safe entrance. If work continues the next morning, the roofer should explain where equipment will remain and how exposed materials will be secured overnight.

Do not accept landscaping protection as an oral side promise if it matters to your choice. Put the important locations into the written scope: the rear deck, the condenser on the east wall, the narrow passage beside the garage and the flower bed under the front valley. The description can be short, but it should be specific enough that the crew receiving the work order understands the plan.

Keys Roofing can inspect the roof and the ground around it, then provide a written scope with measurements and photographs for comparison. To schedule that visit, call (314) 220-2333. Before accepting any proposal, stand at the eave with the bidder and ask one final question: exactly where will everything above us land?
