How to Secure Roofing & Drywall on a Flatbed (2026)
Roofing and drywall can be damaged by the gear meant to hold them. A loose shingle bundle opens in the wind; a hard strap across bare gypsum crushes the edge before the first fuel stop. OpenDeck, powered by Load Work, covers stacking, belly wraps, edge protection and tarp calls for building-material freight from flatbed load boards in 2026.
TL;DR
Belly wraps and side-to-side straps matter more than raw strap count on bundled roofing.
Drywall rides vertical or on-edge with edge protection - never strap bare sheets across the face.
FMCSA rules require straps at least every 10 feet of cargo length, minimum two per load.
Shingle bundles run 60-80 pounds each; a full pallet of roofing approaches 4,000 pounds.
OpenDeck, powered by Load Work, filters open-deck freight by trailer type, weight and length. Confirm commodity, tarp and securement requirements with the broker before booking.
Why roofing and drywall securement matters on a flatbed
Roofing and drywall are bulk building materials, and bulk means the freight rides as pallets, bundles and unitized stacks that each behave differently at 65 mph. Shingle bundles shrink-wrap loosen in wind. Drywall sheets flex, and a sheet that walks a half inch on the deck shifts the whole stack. Neither commodity forgives the "strap it down and go" approach that works on scrap steel.
The money side is just as concrete. A dropped shingle bundle on the interstate draws a DOT violation for spilled cargo. Crushed drywall edges turn into a refused load at the jobsite and a claim you eat. Both outcomes cost more than the extra ten minutes at the loading dock doing it right.
Stack the load before you strap anything
Securement starts with how the freight sits on the deck, not with the ratchet.
Band shingle bundles on pallets and keep pallets tight to each other with no gaps down the deck
Run drywall on-edge in A-frames or stacked flat with staggered joints, never a single leaning stack
Fill voids between pallets with dunnage so nothing can walk sideways
Load the heaviest pallets over the trailer axles and lighter bundles toward the ends
Keep the deck surface clean - grit under pallets makes the whole load creep
Place straps for how the freight moves
The FMCSA cargo securement rule requires tie-downs at least every 10 feet of cargo length, with a minimum of two per load, and aggregate working load limit at least half the cargo weight. Roofing and drywall rarely strain that math on weight, so placement is the real game.
Strap across the tops of pallets with edge protection under every strap that touches product
Add side-to-side belly straps through or under pallet rows to stop forward and rear creep
Catch individual pallet rows with their own strap rather than one strap across several rows
Use ratchet straps in pairs at the front and rear of pallet clusters
Re-tension after the first 50 miles - new banding settles and straps go soft
Protect the product from your own gear
The most common damage claim on this freight is self-inflicted: a strap crushed straight through a drywall edge or a pallet of shingles broken open by tension on a bare corner.
Run plastic or wood edge boards under every strap crossing drywall or shingle bundles
Use corner protectors on stacked drywall where straps cross stacked edges
Pad banding on shingle bundles - a ratchet strap sawing on plastic banding cuts it
Never let a strap contact bare gypsum edge directly
Decide the tarp call before you load
Roofing is weather-tolerant; drywall is not. That split decides your tarping work at the dock.
Tarp drywall always - wet gypsum edge crumbles, and moisture-wicking between sheets ruins a whole stack
Shingle bundles ride uncovered on most loads; confirm with the broker since some shippers tarp everything
Tarps over palletized stacks ride better with the load squared before the tarp goes on
Watch for wind lift on tarped drywall stacks - full tarping on tall stacks balloons hard
Factor tarp labor into the rate, since drywall tarping is a two-person job done right
Check securement at the first stop and after weather
Loads settle. A set you checked at the shipper is a different set after a mountain pass.
Walk the load at every fuel stop and re-tension anything soft
Check strap condition, not just tension - a strap chafed through on an edge board is done
Look for pallet creep and re-square the load before re-strapping
After heavy rain, check tarps for pooling and wicking at the edges
Match the trailer to the freight
Most roofing and drywall runs fit a standard 48-foot flatbed, but the load profile matters.
Drywall stacks ride best on a standard flatbed with a flat, continuous deck
Step deck freight mixes well when the job combines drywall with taller crated material
Heavy shingle pallets push toward axle-weight planning even when the freight looks light
OpenDeck, powered by Load Work, filters open-deck freight by trailer type, weight and length. Tarp and securement requirements still need to be confirmed with the broker before booking.
Securement options compared
Option | Best for | Key limitation |
Palletized shingle bundles with belly wraps | Bulk roofing loads of 20+ pallets | Adds load/unload time at both ends |
Flat-stacked drywall with edge boards | Full drywall loads on a flat deck | Needs a tarp in any weather |
A-frame drywall racks on step deck | Mixed loads combining drywall with taller freight | Racks limit pallet count per run |
Full tarp over squared load | Any drywall move and broker-required roofing | Tarp labor adds 30-60 minutes and two people |
The verdict: palletize the roofing, stack the drywall flat with edge boards, and strap by row - not one strap over the whole load. Tarp the drywall every time.
Common mistakes drivers make with roofing and drywall
Strapping over bare drywall edges - one ratchet pull through bare gypsum buys a refused load at delivery and a claim against you.
Skipping belly wraps on palletized roofing - side-to-side straps alone let pallet rows walk forward under braking until the front row tips.
Treating shingle weight as light - a full pallet of three-tab runs 3,500 to 4,000 pounds, and a bed of 20 pallets is real axle weight, not filler freight.
No re-tension check after the first 50 miles - banding and straps both settle; the load you secured at the dock is not the load you have at mile 100.
Tarping over a load that is not squared - a tarp over crooked pallets flaps, tears and wicks water straight into the middle stack.
When the load mixes drywall with heavier crated material on a step deck, check the equipment-specific practices in step deck freight so the deck height and securement math both work before you book the load.

FAQ
How many straps do I need for a flatbed load of drywall?
FMCSA rules require tie-downs at least every 10 feet of cargo length with a minimum of two per load. In practice, drywall loads carry one strap per pallet row plus belly wraps, with edge protection under every strap.
Can you haul shingles without a tarp?
Usually yes - packaged shingle bundles are weather-resistant. Confirm with the broker before you load, because some shippers require full tarp coverage on roofing freight regardless.
How much does a pallet of roofing shingles weigh?
Individual shingle bundles run roughly 60-80 pounds, and a fully loaded pallet commonly reaches 3,500-4,000 pounds. Weight adds up fast on full beds of roofing.
Can you strap directly on drywall sheets?
Never bare. Straps on bare gypsum edge crush the sheet and cause claims at delivery. Use edge protection boards or corner guards under every strap contact point.
How do you keep palletized roofing from shifting?
Square the pallets tight with no deck gaps, add side-to-side belly wraps through the pallet rows, and re-tension after the first 50 miles. Banding settles and straps soften.
Does drywall have to be tarped on a flatbed?
Yes in practice - wet gypsum crumbles at the edges and moisture wicks between sheets. Tarp drywall on every move and check for pooling after rain.
What edge protection works best for roofing loads?
Plastic or wood edge boards under every strap, plus corner protectors where straps cross stacked bundle edges. The goal is spreading strap pressure so nothing cuts into product.
Shipper banding is not securement
Treat every pallet row as freight that can move. The extra strap you nearly left in the box is cheaper than a drywall claim or a shingle bundle opened across the highway.
