The Real Cost of Hiring the Cheapest Roofer
We get it. A roof replacement is a big number, and when you’re looking at three estimates with three different prices, it’s natural to wonder why you wouldn’t just go with the lowest one. The work looks the same from the street. The shingles are the same color. What’s the difference?
Sometimes there isn’t one. Sometimes a lower price just means a more efficient crew or lower overhead. But more often than not, when one estimate comes in significantly lower than the rest, something is being left out — and what’s being left out is what keeps your roof performing for the next 20 to 25 years.
This isn’t about bashing anyone. It’s about helping you understand what the cheapest roofer vs. the best roofer decision actually looks like — and what it can cost you in the long run.
Where cheap roofers cut corners
A low-price roofing job has to make up the difference somewhere. Here’s where the savings typically come from — and why each one matters:
Skipping or minimizing ice-and-water shield. Ice-and-water shield is one of the more expensive underlayment materials, and installing it properly takes time. A budget job might apply the bare minimum at the eave and skip it in the valleys and around penetrations entirely. In a milder climate, you might get away with that. In Maine, it’s an invitation for ice dam damage within a few winters.
Reusing old flashing. Removing old flashing and installing new step flashing, counter-flashing, and valley flashing properly is labor-intensive. A cheaper crew may leave the old flashing in place and just seal over it with roofing cement. Cement cracks within a few years — especially through Maine’s freeze-thaw cycles — and when it does, you’ve got a leak around your chimney or wall junction.
Layover instead of tear-off. Installing new shingles on top of old ones eliminates the labor and disposal cost of a full tear-off. It also hides whatever’s underneath — rotted decking, failed underlayment, nail pops. Most shingle manufacturers will void their warranty on a layover installation, which means you’re paying for new shingles with no product protection if they fail.
Using lower-grade materials. Not all shingles are the same. An estimate that just says “architectural shingles” without naming the manufacturer or product line could be using an economy product with a shorter lifespan, lower wind rating, and weaker warranty than premium options from Owens Corning or CertainTeed. The difference may be a few hundred dollars on the estimate — and five to ten years of roof life.
Rushing the job. Speed saves labor cost. But speed also means nail guns fired too fast (high nails that don’t seat properly), shingle courses that aren’t straight, flashing that’s bent rather than precision-cut, and a cleanup that leaves nails in your lawn. A rushed job looks okay from the street on day one. It doesn’t look okay in year three.
Skipping ventilation. Assessing and correcting attic ventilation takes time and sometimes adds materials. A cheaper crew installs what’s on the plan and moves on — even if the existing ventilation is inadequate. As we’ve written about, poor ventilation leads to ice dams, premature shingle failure, and voided warranties.
What a cheap roof actually costs you in the long run
Let’s put some real numbers to this. Say you get three estimates for a roof replacement:
Contractor A: $11,000
Contractor B: $16,500
Contractor C: $17,000
Contractor A is $5,500 cheaper. That’s a significant difference. But here’s what might be behind it:
No ice-and-water shield in valleys. Ice dam leak in year 3 — interior repair: $2,500
Reused chimney flashing fails in year 4. Leak and flashing repair: $1,800
Economy shingles fail 5 years early. Replacement at year 18 instead of 25: $14,000
Voided warranty from layover installation. No manufacturer coverage when shingles curl prematurely: priceless frustration
The $5,500 you saved upfront can easily become $10,000 to $20,000 in additional costs over the life of the roof. And that’s before you factor in the disruption, the stress, and the time spent dealing with problems that didn’t need to happen.
What you’re actually paying for with a quality roofer
When a quality roofing contractor charges more, here’s what that money is going toward:
Complete protection. Full tear-off, proper ice-and-water shield placement, new flashing at every penetration, correct drip edge installation, and ventilation that’s been checked and corrected if needed. Nothing skipped, nothing shortcut.
Premium materials. Named products from trusted manufacturers with real warranty backing. Not “architectural shingles” — a specific product line you can look up and verify.
Craftsmanship. Precision-cut flashing, straight coursing, properly seated nails, and the kind of attention to detail that you’ll never see from the driveway but your roof will benefit from for decades.
Real warranty protection. A manufacturer’s product warranty that’s valid because the installation was done to spec by a certified contractor. A workmanship warranty from a local company that will actually be here to honor it.
The whole experience. Clear communication, protected landscaping, daily cleanup, a final walkthrough, and someone who answers the phone if you have a question six months from now.
The difference between the cheapest roofer and the best roofer isn’t just the number on the estimate. It’s what that number buys you over the next 25 years.
How to tell the difference before you hire
You don’t need to become a roofing expert to spot the difference between a good deal and a too-good-to-be-true deal. Here’s what to check:
Compare estimates line by line. If the cheapest estimate doesn’t mention ice-and-water shield, new flashing, or drip edge, those steps may not be included. A lower price that’s missing critical work isn’t a fair comparison.
Ask about materials by name. If the contractor can’t tell you the manufacturer and product line, that’s a concern. You should know exactly what’s going on your roof.
Check for certifications. Manufacturer certifications like Owens Corning Preferred Contractor or Brava Preferred Contractor mean the manufacturer has vetted the installer. That protects your warranty and signals a commitment to quality.
Ask about their workmanship warranty. One year? Two? Five? None? The length of the workmanship warranty tells you how confident the contractor is in their own work.
Look for local roots. A contractor who lives in the community, has a local address, and has been here for years has a different relationship with accountability than someone passing through after a storm.
Frequently asked questions
Why are some roofing estimates so much cheaper than others?
The most common reasons are: skipping steps (no ice-and-water shield, reusing old flashing), using lower-grade materials, doing a layover instead of a full tear-off, or not including cleanup and disposal in the price. Occasionally a lower price reflects lower overhead or a smaller crew, but if the difference is more than 20–30%, it’s worth asking what’s being left out.
Is a more expensive roofer always better?
Not automatically. Price alone doesn’t guarantee quality. The key is comparing the scope of work, materials, and warranty coverage between estimates — not just the total. The best value is a complete job with quality materials, proper installation details, and real warranty protection at a fair price.
How do I know if an estimate is leaving something out?
Check for ice-and-water shield, new flashing, drip edge, cleanup and disposal, and warranty details. If any of these are missing, ask about them specifically. We wrote a full guide on how to read a roofing estimate that walks through what every section should include.
What’s a fair price for a roof replacement in Maine?
For a typical Maine home, an asphalt shingle roof replacement with a full tear-off, proper underlayment, ice-and-water shield, new flashing, and quality materials typically ranges from $10,000 to $25,000. Standing seam metal runs $20,000 to $40,000. The price depends on roof size, pitch, complexity, and material choice. If an estimate falls significantly below these ranges, it’s worth understanding why.
We’re not the cheapest roofer in Maine. We’ve never tried to be. What we try to be is the roofer you’re glad you chose five years from now — when your roof is still performing, your warranty is intact, and you haven’t spent a dollar on repairs that shouldn’t have been necessary.
