Get the same shingle quoted in writing at two or more distributors, then give most of your orders to one rep who knows you hold the other number. Pay inside the terms, which at ABC Supply start at net 30, because ABC says a clean payment record is what unlocks wider terms later. If you install Owens Corning, its contractor rewards come on top of whatever price the branch gives.
A new owner’s quotes on one shingle ran from $105 to $130 a square
A contractor starting a roofing division wrote on Reddit, “Being new accounts at the supply house my shingles are $140+ a sq.”
Another owner starting a roofing company priced Atlas Pinnacle Pristine at Beacon, ABC, SRS, MBS and Menards. SRS and MBS quoted him between $116 and $130 a square.
Menards was $118 a square, or $105 after its rebate, and it delivers to the job only as a ground drop. Those were quotes to a new account in one owner’s market.
Get your main shingle line and its accessories quoted in writing at each supplier, with delivery included, and compare the totals.
Home Depot now owns SRS, and QXO owns Beacon
Home Depot closed its purchase of SRS Distribution on June 18, 2024. QXO closed its purchase of Beacon Roofing Supply on April 29, 2025. ABC Supply was not part of either deal.
If your first account is at one of these three, open the second at one of the other two, so your two quotes come from companies that don’t share an owner.
ABC wants a personal guarantee from companies under five years old
ABC Supply’s credit application sets terms at net 30 once credit is approved. If the business has operated for less than five years, someone has to sign a personal guarantee, and the guarantor then personally guarantees all of the company’s debt to ABC, plus any late charges. Every past-due account pays a monthly late fee, capped at the most that state and federal law allow.
Read the guarantee before you sign it, because it puts your own money behind every order charged to the account.
For a large project, ABC runs job accounts that add purchasing power on that one job. ABC says the payment record from a job account helps a younger business qualify for wider terms later. If a big job comes along before your account has much history, ask the branch about a job account before you place the order.
ABC says supplier credit is often interest-free inside the terms
ABC’s contractor guide says supplier credit is often interest-free within its stated terms of net 30 or net 60, with late fees after that.
The same guide puts a bank line of credit at about 8 to 14% APR and business credit cards at about 20% or more.
Free credit only helps when the customer’s money arrives before the supplier’s due date. A commercial roofing poster on Reddit wrote that net 30 was new to them, and floating costs that long forced their office manager to push back a supplier payment.
Before material ships for a big job, set the job’s payment schedule beside the supplier’s due date and close any gap first. Roofing Cash Flow: Depreciation Checks, Final Payments and Liens covers the money side of that wait.
Put most of your buying through one rep, and keep a second quote
A small Northeast roofing and siding owner on r/Contractor, choosing between ABC and Lansing, wants as much of his buying as possible to go through one supplier and one rep. He wrote that “these suppliers and reps have discretion on what kind of pricing they offer each customer.”
A small Florida roofing owner feels the other side of that. In a YouTube comment, he wrote that large competitors avoid the increases he pays: “They don’t get a price increase from supplier because they invest millions but I do.”
Give one rep steady orders and pay on time. Once you hold a current written quote from a second supplier, ask the rep for a pricing review with it in hand. Then run the new number through How to Price a Roof: Price per Square, Overhead and Target Margin to see what it does to each job.
Owens Corning pays rewards on its shingles from any distributor
Owens Corning’s contractor rewards program pays points or promotional funds on qualifying OC products bought from any local distributor: architectural shingles, starter, hip and ridge, and underlayment. You upload your distributor invoices within 60 days of the invoice date, and processing takes 5 to 7 business days. The points can buy marketing materials and branded gear, or go onto a reloadable program Mastercard as cash.
Owens Corning pays the rewards itself, and they count no matter which branch you buy from, so they come on top of the price your rep gives you.
Upload invoices every month so none of them ages past 60 days, and ask your rep which manufacturer programs cover the lines you install. GAF, Owens Corning, CertainTeed and Atlas Certification: What It Takes and Whether It Wins Jobs covers the manufacturer side in more depth.
Price increases and return credits show up on the invoice, so check each one
In March 2026, a poster on r/Roofing asked whether others were seeing a 5% to 8% price increase from SRS. A contractor commenting on YouTube said that material ordered before an increase but delivered after it gets billed at the higher price, even when the supplier already has it in the warehouse.
One owner on Reddit suggested a hedge against tariff increases: prepay a bulk order now and take delivery later. It ties up cash up front, and the order can be cancelled if prices rise fast.
An office worker at a roofing company wrote that their major supplier didn’t credit the full price on returned material. The supplier called the difference a cash discount for cash-paid invoices, even though the company pays by card.
A roofing sales rep wrote that his company’s invoice for GAF, CertainTeed or Owens Corning material sometimes came out higher than what a walk-in customer would pay.
