Product details

The value weight in the line at 85 gsm, and the one that ships the most rolls per pallet at 72. Built for high-turn residential work where the underlayment is covered the same day.

Still a woven synthetic rather than felt, so it does not wrinkle when it gets wet, does not tear at the cap nail, and gives the crew a grippier walking surface than a 30 lb felt on a warm deck.

Compare against

Those are your numbers. Adding puts 5 pallets of Underlayment 85 gsm in your container, and the volume discount is applied at checkout.

Assumption: About 1.1 rolls per 10 squares, after course overlap. A square is 100 sq ft, so a 30 square roof is 3,000 sq ft. Both columns are priced on the same roll count. Change the inputs above and every figure updates. These are planning estimates for sizing an order, not a quote. Final DDP pricing is confirmed against your delivery address before anything ships.

Common questions

How much do I save on underlayment 85 gsm?
$53.17 every roll, which is 63 percent below QXO's delivered price of $84.84. Across the 4 pallet minimum, which is 288 rolls, that is $15,587 on a single order, including the 3% volume discount that order size earns.
How does the volume discount work on this line?
It comes off automatically at checkout, on top of the price shown. 4 pallets or more takes 3 percent off, 8 pallets or more takes 5 percent off, 12 pallets or more takes 8 percent off. This line has a 4 pallet minimum, so the smallest order you can place already earns 3 percent, worth $274.
What is the minimum order on underlayment 85 gsm?
4 pallets, which is 288 rolls and works out at $8,847.32 delivered duty paid after the 3 percent volume discount. One pallet is 72 rolls at $2,280.24.
Is freight on top of this price?
No. $31.67 per roll is DDP: product, ocean and inland freight, insurance, customs clearance, import duties and tariffs, and delivery to your destination are all inside it. The distributor prices we compare against are delivered prices too, so the gap is like for like.

$15,587 is sitting in one order of this.

That is the gap on the 4 pallet minimum alone, before the volume discount. Not ready to commit? Samples are $5 for the whole order, so you can check the goods on your own gun first.
