The first quarter of 2026 has been a gut-check for anyone moving building materials. Between diesel prices creeping up, lumber shipment volumes sliding, and energy costs tied to the ongoing Middle East situation, the margin pressure on suppliers right now is real. Input prices rose at a 12.6% annualized rate in the first two months of 2026, and it doesn’t look like that eases anytime soon.
If you’re running a lumber yard, drywall supply house, or roofing distribution operation, here’s what’s worth paying attention to.
The Diesel Problem Is Upstream, Not Just in Your Fleet
Diesel isn’t just hitting your delivery trucks – it’s squeezing everyone in the supply chain above you. Logging operations are facing margin compression that could lead to supply cuts in the back half of 2026 if diesel prices hold or climb. Weyerhaeuser’s wood products segment saw shipment volumes drop 5% year-over-year in February, partly a demand story but also a cost story. Fewer logs moving, less lumber milled, tighter supply hitting distributors and dealers.
The practical impact: lead times may stretch. If you’ve been quoting contractors on 3-5 day delivery windows, now’s the time to pressure-test that assumption against your actual inbound supply schedule.
Contractors Are Already Jumpy – Don’t Let Delivery Be the Thing That Sets Them Off
There’s a broader mood problem on jobsites right now. Between “Build America, Buy America” compliance headaches slowing affordable housing projects, tariff uncertainty from last year, and financing pressures, contractors are operating with less slack. They’re watching every dollar and every day on the schedule.
That’s the context in which your drivers are showing up. A short load, a delivery window missed by three hours, or a disputed quantity – any of those can blow up into a credit dispute or lost account when a contractor is already stressed. This is exactly when documentation on every delivery stops being a nice-to-have and becomes actual risk management.
The Procurement Technology Gap Is Widening
Field Materials just crossed .3 billion in construction purchasing volume – a 3.5x year-over-year jump – driven in large part by data center construction. That’s a signal: larger contractors and commercial GCs are getting more sophisticated about procurement tracking. They know what they ordered, they know what they expect, and they have data to back it up.
For suppliers, this raises the bar. If a commercial GC has a digital purchase order and your driver shows up with a paper ticket and no photo documentation, you’ve already put yourself at a disadvantage in any quantity dispute. The suppliers who are building durable relationships in this environment are the ones who can match that accountability standard.
Three Things to Tighten Up Before Q2 Gets Worse
- Review your delivery windows. Are the windows you’re quoting still realistic given tighter supply and higher fuel costs? Honest timelines beat missed ones every time.
- Document every delivery. GPS timestamp, photo at drop, quantity confirmation – not just for disputes, but to build a track record that earns contractor trust. Tools like ezPOD make this straightforward for drivers without adding paperwork burden.
- Communicate proactively on backorders. With shipment volumes declining, you’re going to have more incomplete orders. A proactive call when you know it’s coming beats a contractor calling you when framing is stalled.
The Bottom Line
2026 is shaping up to be a year where the suppliers who survive margin pressure are the ones with tight operations and strong contractor relationships. Costs are up, supply is tightening, and the contractors you’re delivering to are under their own pressure. The suppliers who document well, communicate early, and show up when they say they will are going to come out of this stronger. The ones who don’t are going to lose accounts they can’t afford to lose.
Tighten the back half of Q1. Q2 isn’t going to be easier.
