You have probably heard the advice a hundred times: always get at least three quotes before hiring a roofing contractor. It is repeated on every home improvement blog, in every neighborhood Facebook group, and by well-meaning family members who once had a roof replaced in 2004. The advice sounds reasonable on its surface. More quotes should mean more information and better decision-making, right? Not necessarily. In fact, chasing a magic number of quotes can actually lead you to a worse decision – and a worse roof – than being strategic about who you invite onto your property in the first place. Here is why the “get three quotes” rule deserves a serious second look, and what Central Illinois homeowners should focus on instead.

Comparing roofing quotes is smart – but only if you are comparing apples to apples. Most homeowners unknowingly compare completely different scopes of work, materials, and warranty terms.

Where the “Get 3 Quotes” Advice Comes From

The three-quote rule originated as consumer protection advice decades ago when homeowners had almost no way to verify a contractor’s reputation before hiring them. There were no Google reviews, no Better Business Bureau online profiles, no state license lookup databases. Knocking on a contractor’s door and asking for references was about as deep as due diligence went. In that environment, getting multiple quotes made sense as a basic safeguard against being dramatically overcharged.

The logic was simple: if three contractors all price a job around $12,000 and one comes in at $25,000, you know something is off. The multiple-quote approach was essentially a crude averaging tool. It still has some validity in that narrow context – but roofing in 2026 is a completely different landscape than roofing in 1995, and the advice has not evolved with the industry.

Today you can verify a contractor’s state license, read hundreds of customer reviews, check their manufacturer certifications, view their completed projects online, and confirm their insurance coverage – all before they ever set foot on your property. The information asymmetry that made the three-quote rule necessary has largely disappeared. What has not disappeared is the advice itself, and homeowners who follow it blindly often end up more confused, not less.

The Problem With Collecting Quotes Like Baseball Cards

Here is the dirty secret about roofing quotes that nobody talks about: three quotes from three different contractors are almost never comparing the same thing. Roofing is not a commodity like gasoline where the product is identical regardless of who sells it. Every roofing quote involves dozens of decisions about materials, methods, and scope – and different contractors make different assumptions about all of them.

Material quality varies enormously. One contractor quotes Owens Corning Duration architectural shingles with a Lifetime Limited Warranty. Another quotes a builder-grade three-tab shingle that costs 40% less but lasts half as long. Both quotes say “new roof” but you are getting radically different products. Unless you know exactly what to look for, the cheaper quote looks like a better deal when it is actually a worse value.

Scope differences hide in the details. Does the quote include tearing off the existing shingles down to the deck, or are they layering over? Does it include replacing damaged decking boards, or is that an add-on you will discover on day one of the project? Does it include new drip edge, ice and water shield in the valleys, proper ventilation, and pipe boot replacements? The answers to these questions can represent thousands of dollars in difference – and a contractor who skips these items will always come in cheaper on paper.

Warranty terms are not standardized. “Lifetime warranty” means completely different things from different manufacturers and different installers. An Owens Corning Preferred Contractor can offer warranty coverage that a non-certified installer simply cannot match – including workmanship coverage that survives even if the installing company closes. When you compare quotes without comparing warranty specifics you are ignoring one of the most important variables in the entire decision.

What Actually Matters More Than the Number of Quotes

Instead of fixating on how many quotes you collect, focus on the quality of the contractors you are considering. Two quotes from verified, credentialed contractors will give you dramatically better information than five quotes from unknown companies you found on Craigslist. Here is what to evaluate:

Contractor Credentials and Certifications

Start with the basics. Does the contractor hold a valid Illinois roofing contractor license? You can verify this at the Illinois Department of Financial and Professional Regulation website. Campbell Construction holds Illinois License 104.015328 – and we encourage every homeowner to verify it. Beyond state licensing, look for manufacturer certifications. Being an Owens Corning Preferred Contractor and Duro-Last Certified Installer means the contractor has met specific training, insurance, and quality standards set by the manufacturer. These certifications are not participation trophies – they require ongoing compliance and they unlock warranty tiers that non-certified installers cannot offer.

Warranty Quality – Not Just Warranty Length

Every contractor will tell you their roof comes with a warranty. The question is what that warranty actually covers and who stands behind it. There are three types of warranty coverage you should understand:

That third tier – the Enhanced System Warranty – is only available through certified preferred contractors. It is the gold standard because it eliminates the risk of your workmanship warranty evaporating if the installing company goes out of business five years from now. This is a critical differentiator that does not show up when you are comparing quotes purely on price.

Installation Standards and Process

Ask each contractor to walk you through their installation process step by step. A quality residential roofing installation should include: complete tear-off of existing materials down to bare decking, thorough deck inspection with replacement of any damaged or rotted boards, installation of ice and water shield in valleys and at eaves, proper starter strip and drip edge installation, manufacturer-specified nailing patterns, ridge vent or equivalent ventilation, and new pipe boot flashings. Any contractor who cannot articulate this process in detail – or who glosses over it – should raise a red flag regardless of their price.

Local Reputation and Track Record

A contractor who has been operating in your community for decades has something no out-of-town company can match: accountability. Campbell Construction has been headquartered at 1627 IL-78 in Jacksonville since 2000. We are not going anywhere. Our crew members live in the same communities where we install roofs. Our trucks drive the same streets. When we tell you the job will be done right and we will stand behind it – you know exactly where to find us. That kind of long-term local presence is worth more than any discount from a contractor whose business address is a P.O. box in another state.

A professional roofing crew performs a complete roof replacement. The quality of installation matters far more than the price on the estimate – this is where roofs are won or lost over the long term.

How to Compare Roofing Quotes Fairly

If you do decide to get multiple quotes – and there is nothing wrong with getting two or three from contractors you have already vetted – here is how to make the comparison meaningful instead of misleading:

Require written, itemized estimates. A one-line quote that says “New roof – $14,500” is useless. You need line items for tear-off and disposal, decking repair allowance, underlayment type and brand, shingle brand and product line, flashing and drip edge, ventilation, cleanup, and warranty terms. If a contractor will not provide this level of detail, that tells you everything you need to know about how they run their business.

Specify the same materials across quotes. Tell each contractor you want pricing on the same shingle product – for example, Owens Corning Duration in a specific color. This eliminates the single largest variable in quote comparison and lets you see actual differences in labor, overhead, and margin rather than apples-to-oranges material cost differences.

Confirm the scope is identical. Does each quote include the same number of layers to tear off? The same ventilation approach? The same flashing replacement scope? If one quote assumes one layer of tear-off and another assumes two, the comparison is meaningless. Get clarity on every scope item before you compare bottom-line numbers.

Compare warranty terms side by side. Write down exactly what each contractor’s warranty covers, how long it lasts, and whether it is backed by just the contractor or by the manufacturer as well. A roof that costs $1,500 more but comes with a manufacturer-backed Enhanced System Warranty is almost always the better investment over a 25-year roof lifecycle.

If you request this level of detail from every contractor and one of them cannot or will not provide it – that contractor just eliminated themselves from consideration regardless of price.

Why the Cheapest Quote Is Often the Most Expensive Decision

This is the part of the conversation that makes some homeowners uncomfortable but it is the most important thing we can tell you after 25 years in this business: the cheapest roofing quote almost always ends up costing you more in the long run.

A low-bid contractor cuts costs somewhere. They have to. Roofing materials cost roughly the same for everyone – suppliers do not offer secret wholesale pricing to companies that underbid the market. Labor in Central Illinois has a floor based on what skilled roofers can earn. Insurance, licensing, equipment, and overhead are relatively fixed costs. When a quote comes in dramatically lower than the competition, the savings are coming from one or more of these places:

Cheaper materials. Builder-grade shingles instead of architectural. Felt paper instead of synthetic underlayment. No ice and water shield. Reusing old flashing and pipe boots instead of replacing them. These shortcuts save money today and cost you thousands in premature failures, leaks, and shortened roof life.

Fewer workers or less experienced crews. A crew of two takes twice as long as a crew of four, which means your home is exposed to weather for longer during the project. Inexperienced laborers work for less but make installation errors that void manufacturer warranties and cause premature failures.

Skipped steps. Not replacing damaged decking. Not installing starter strip correctly. Using fewer nails than the manufacturer specifies. Not properly sealing penetrations. These are invisible on day one but they are the reason some roofs fail at year seven while others last thirty.

No insurance or inadequate coverage. If an uninsured or underinsured worker is injured on your property, your homeowner insurance policy is potentially liable. This is not a hypothetical risk – it happens in Central Illinois every year. Always verify a contractor’s general liability and workers compensation coverage before allowing them on your roof. Contact us and we will provide our certificates of insurance within 24 hours.

A quality roof installed by a certified contractor protects your home for decades. The difference between a $10,000 shortcut and a $14,000 proper installation is measured in decades of performance – not just dollars on an estimate.

What a Campbell Construction Estimate Includes

Every estimate we provide is a detailed, written, itemized document that leaves nothing to guesswork. Here is exactly what you will receive when you request a free roofing estimate from our team:

Complete material specifications. We list every product by manufacturer, product name, and model number. You will know exactly what brand of shingles, underlayment, ice and water shield, drip edge, ridge vent, starter strip, and flashing will be installed on your roof. No generic descriptions, no vague “contractor’s choice” language.

Itemized pricing. Every line item is broken out separately – tear-off, disposal, decking inspection and repair allowance, each material component, labor, and cleanup. You can see exactly where every dollar goes. This makes our estimates directly comparable to any other itemized quote you receive.

Project timeline. We tell you when we will start, how long the project will take, and how many crew members will be on site. Most residential roof replacements are completed in one to two days. We do not leave your home exposed overnight unless weather forces a delay – and we tarp if that happens.

Warranty documentation. We spell out exactly what warranty coverage your new roof will carry – manufacturer material warranty, our workmanship warranty, and the Enhanced System Warranty available through our Owens Corning Preferred Contractor status. No fine print surprises.

Insurance and licensing verification. Our Illinois License number (104.015328), general liability coverage, and workers compensation coverage are included with every estimate. We want you to verify us – because we know we pass every check.

Whether you need a roof inspection first or you are ready for a full replacement estimate, our process is designed to give you complete information so you can make a confident decision – not a confused one.

The Counter-Intuitive Truth: 2 Good Quotes Beat 5 Random Ones

Here is our honest advice after installing thousands of roofs across Jacksonville, Springfield, and the surrounding Central Illinois communities: two quotes from verified, licensed, manufacturer-certified contractors will give you better information than five quotes from companies you have never heard of.

When both contractors you are comparing are credentialed, insured, and using the same caliber of materials – the quotes will be much closer together. The differences that remain will be meaningful: one may include a ventilation upgrade the other does not, one may offer an Enhanced System Warranty the other cannot, one may have a more experienced crew with a faster timeline. These are real differentiators you can evaluate intelligently.

Compare that to five quotes from a mix of licensed contractors, storm chasers, a guy your neighbor knows, and a company that advertised on a yard sign. The spread between the highest and lowest bid might be $8,000 or more – and you have no way to know which quote is the right one because the scopes, materials, and contractors are so different that no meaningful comparison is possible. You end up more confused than when you started, and the temptation to just go with the cheapest option becomes overwhelming.

Quality over quantity. Vet your contractors first. Then get quotes from the ones who pass your screening. The right number of quotes is not three – it is however many it takes to have two options you genuinely trust.

When You Actually Should Get Multiple Quotes

We are not saying you should never compare prices. There are specific situations where getting multiple quotes is genuinely helpful:

Large commercial projects. If you are replacing a commercial roof or a multi-building property, competitive bidding on a fixed scope of work makes sense because the dollar amounts are large enough to justify the time investment.

Insurance claim disputes. If your insurance adjuster’s estimate seems low, having an independent contractor estimate to compare against gives you leverage in the supplement process.

When you have no trusted contractor relationship. If you are new to an area or have never needed a roofer before, getting two to three quotes from vetted contractors helps you establish a baseline and build a relationship with a company you trust. Just make sure you vet them first – do not use the quote process as your vetting process.

If you are a Central Illinois homeowner and you already have a relationship with a licensed, certified local contractor who provides detailed written estimates and manufacturer-backed warranties – you probably do not need to shop around. You need to make a decision based on the quality of what is in front of you, not on an arbitrary rule about collecting a certain number of proposals.
