The Lowest Bid Lie: When a Cheap Roofing Quote Turns Costly

Quick answer: A roofing bid that’s far lower than the others often leaves out items you’ll pay for later: decking replacement, extra tear-off layers, code-required drip edge or ventilation, permits, disposal or flashing. Those come back as change orders once the job has started. Compare bids on completeness, not price: a complete estimate lists materials, code items, permits, disposal, how decking is priced and a clear change order policy.

There’s a saying in construction: the cheapest price usually comes with the most expensive surprises. Some contractors know you’re comparing bids and leaning toward the lowest one, so they build their bid to win on price, not completeness.

How Does the Lowball Bid Strategy Work?

The estimate looks competitive, often much lower than the others.
You sign, and the job starts fast.
Then “unexpected issues” appear: rotted wood they didn’t mention, an extra layer “they didn’t see,” code-required ventilation or flashing “they forgot.”
Change orders follow, one after another. Each sounds reasonable. Together they add thousands.
By then you’re too far in to back out.

Frequently Asked Questions

Why are roofing quotes so different?

Differences in materials, scope, code items, labor quality, insurance, warranties and what’s left out can create big price gaps.

What is a change order in roofing?

A written change to the original contract, usually adding cost for work not in the original scope, like replacing rotted decking.

How is decking replacement usually priced?

Many contractors price it per sheet of plywood or OSB. Ask for that price in writing before the job starts.

Is the cheapest roofing bid ever the right choice?

It can be if the scope is truly complete and the contractor is qualified and insured. Compare line by line, not just the total.
