Profit margins tend to be razor-thin in residential home building. As a result, this can lead builders to choose a cut-rate roofing subcontractor. They figure, “I’ll save a few hundred dollars per square foot this way.”
Sure, the upfront costs will shrink. However, hiring a subcontractor based on who makes the lowest bid is one the most expensive mistakes a home builder can make. The long-term operational costs often turn that cheap roof into a financial and reputational nightmare.
Keep reading to find out why it’s a bad idea to select the lowest bidder when evaluating subcontractor bids for a new subdivision or a custom build.
The Consequences of Hiring the Cheapest Bidder
To sustain low bids, roofing crews will often use untrained labor, rush through installations, and neglect critical structural details. The most common consequences we see from this are things like:
- Improper flashing around valleys and chimneys
- Incorrect nail placement (high-nailing or over-driving)
- Skimped ventilation setups
These mistakes are rarely visible during a standard walkthrough. Instead, they remain hidden until the first severe seasonal hailstorm, heavy snowfall, or high-wind event. By that point, it’s been months since the new owners have moved in.
Now, when a cheap roof fails prematurely, the homeowner doesn’t call the anonymous subcontractor who nailed down the shingles. They call you, their builder. It doesn’t matter if the shoddy workmanship wasn’t your fault. You were their main point of contact and the one they entrusted the job to. So, the blame will ultimately land on you.
It’s not just a loss of trust you’ll have to deal with either.
Builder Warranty Nightmares & Unexpected Costs
A single major roof leak can easily erase the profit margin of an entire build. Here’s what the worst case scenario looks like:
The Roofing Subcontractor Disappears on You
Cut-rate roofing contractors are notoriously unreliable. When issues pile up, these companies frequently dissolve, change names, or simply ignore your phone calls.
You Discover the Manufacturer Warranty Is Now Void
Shingle manufacturers enforce strict installation guidelines. If a subpar crew high-nails the shingles or cuts structural corners, the manufacturer will void the material warranty. You’re suddenly left holding 100% of the liability.
Then You Realize the Damage Is Much, Much Worse
Roof leaks rarely damage just the roof. They destroy attic insulation, ruin custom ceiling drywall, short out electrical fixtures, and ruin hardwood flooring. In turn, this exponentially increases your builder warranty expenses.
You Get Stuck Footing the Bill
Your warranty won’t cover the costs. The shingles manufacturer won’t cover the costs. And your customer most definitely won’t help cover the costs. This leaves you footing the repair bill entirely. Not only that, the time you’re going to spend on doing the repairs, handling emergency service calls, and managing mold remediation is going to eat away at whatever profits remain.
Protect Your Bottom Line and Reputation with a Reputable Partner
Cheap roofing crews aren’t faster than other companies. They’re able to make more competitive (i.e. too-inexpensive-to-be-true) bids by cutting corners.
While their business might take a small hit if things go south with the roof they’ve built and installed for you, your home builder business is likely to take an even bigger one.
Even if the worst case scenario depicted above doesn’t happen, your business is going to face major financial consequences.
Smart builders view roofing not as a commodity, but as a critical structural component. Don’t let a cheap roofing bid cost you your profit, peace of mind, or your reputation.
