How Do I Compare Proposals From Different Roofing Contractors?

6 min read

TL;DR: Summary

Comparing roofing offers is more like a job interview for the contractor than a simple price comparison. While quotes and estimates provide a basic price, a true proposal is a detailed, binding contract that outlines the specific scope of work, material types, and labor responsibilities.

Because roofing is a competitive market, most reputable bids will be similar in price; a drastically lower bid is often a red flag indicating that a contractor is cutting corners on permits, insurance, or high-quality materials. 

Are you in need of a new roof and feeling stressed about finding the proposal that’s right for you? Maybe you’re experiencing leaks on your roof and are feeling the pressure to get started right away. Or perhaps you want to take your time to find the best offer but are feeling overwhelmed with all the different options.

We get it. Replacing your roof is a big deal, and nobody wants to spend that much money just to regret it or have problems down the line. That’s why we at RoofSmart want to help you by sharing our tips for comparing proposals.

Our sales team at RoofSmart explains our proposals to hundreds of customers every year. And yes, many times we will even explain to homeowners what they are being offered in other proposals vs. ours. We know what we offer and what our competition offers. That’s just the nature of the business.

While we’d love to be the ones to help you with your roofing needs, we believe that you deserve clear answers about roofing proposals. You also deserve the opportunity to find the roofer and the offer that is the best fit for you.

This article is going to tell you what to look for in a proposal, how to evaluate a roofing contractor, and why all of this is important for the proposal comparison process. After reading this, you’ll be able to compare proposals with ease and confidently choose the one that is best for you.

Understanding the Differences: Roofing Quotes, Bids, Estimates, and Proposals

When you are meeting with different roofing contractors to figure out how much your new roof will cost, there are a variety of ways that they’ll share this information with you. It’s important to know the differences between them so that you can compare them accurately.

In general, quotes, bids, and estimates are pretty similar. They provide you with pricing for a project, but they usually do not have much detail. None of these are binding contracts, they are simply a way for you to get a feel for the cost of the roofing job.

But, a proposal is often tailored specifically to you. It contains detailed information about the scope of the project, the price, and the other things that you will be charged for. Once signed, this would become a binding contract.

It’s not possible to adequately compare a quote, bid, or estimate to a proposal because of the drastic difference in what’s included. If you only have a price with no other information, you don’t know what the roofing contractor is planning to do.

If you don’t have a proposal from all the roofing contractors that you’re considering hiring and you’d like to compare the prices they’ve given you, it would be most helpful to get a proposal from all of them.

Otherwise, there’s no way to be sure what each roofer will be doing.

What to Look For In the Roofing Project Proposal

  • Cost: Each proposal will include the cost of the overall project, which includes the price of the shingles (or other type of roofing material) that you’d like to use and the cost of labor required to install them.
  • Scope of work: Every good proposal will describe the scope of work for the job. This means that there should be an explanation behind each cost. This might include details about the prices of different shingles, or indicate what steps the roofing crew will take while replacing your roof. This is where you’ll find recommendations for what you should fix or replace on your roof and the different options you have for doing so. Typically, this is about any other steps that go beyond the roof replacement itself. For example, if you would like to install new skylights, your siding needs to be replaced, you want a roof deck installed, or a leaky pipe boot needs to be replaced, this should all be clearly stated in the proposal.
  • Who is doing the work: This is where the roofing contractor would say whether they are doing the work themselves or if they are hiring subcontractors to do some or all of the work and how much it costs to pay them.
  • Permits, taxes, and other mandatory fees: There are a variety of taxes and fees that add to the cost of the job. Roofing contractors will include calculations of the different taxes that you must pay. They will also mention if any permits are required, but for some permits, we won’t know the price until we pull it.
  • Warranties: Warranty information should also be included in the proposal. This includes the warranty that the shingle manufacturer offers and the warranty that the roofing contractor offers.

All of the proposals that you receive should include these elements and should be pretty similar in cost. Roofing is a competitive market, so there is no price fixing. Everything is a market rate.

If you’re noticing big differences in what is included in the proposals it could mean a few different things:

  1. Some of the documents you’re looking at are quotes, bids, or estimates, and do not accurately describe the entire cost of the project
  2. Your roofer is not a reputable source and might be trying to hide information from you or cut corners to reduce costs. If there is a drastic difference in costs, check the explanations to find out why.

Both of these scenarios make it difficult to compare prices and immediately indicate that you probably shouldn’t work with that roofing contractor if they won’t give you an in-depth proposal.

Red Flags to Watch Out For in Roofing Proposals

If the proposal is vague and does not say what will happen during the job or offer any sort of explanation for what is included in the cost, then that is not a good sign. This is an industry-wide issue that happens all the time.

There should be some sort of reasoning behind every price that is provided to you, and we’d strongly recommend that you always ask about pricing if it is vague or unclear.

If the roofing contractor is not willing to answer your questions about cost (both in person and in the proposal) then that is also a major warning sign that they are not a reliable option.

Similarly, the proposal should be specific to you. This means that even if there is an explanation for what’s included, it should not feel generic.

There should be details or work added that meets the particular needs of your roof because this demonstrates that the roofing contractor was listening to your requests and is genuinely invested in fixing your roof’s issues.

You cannot accurately compare prices from proposals that don’t contain similar information or are missing important details. Some of these important details include disclaimers excusing roofers from responsibility for property damage.

Always read the fine print and make note if the roofing contractor tried to hide it at the end of the proposal. If you get the impression that they were hoping you wouldn’t see that part, then you probably don’t want to work with them.

If you are noticing that some of your proposals contain these red flags, the good news is that this can make the comparison process easy.

Instead of comparing prices and other specific details, you can compare proposals based on who seems more reputable and willing to openly communicate with you.

How to Ensure You’re Getting a Fair Deal From a Roofing Contractor

Comparing proposals is about more than just looking at prices or thinking about the work that needs to be done. It is equally (if not more!) important to find a roofing contractor that you trust to treat you fairly and do a good job.

For example, a lot of people treat buying a roof like buying a car. But really it’s more like buying a car that comes shipped in pieces to your driveway and you’re looking for somebody to put it together. And so in that scenario, it’s more about who is putting it together. Looking at proposals is more of a job interview than an evaluation of products and prices.

A good way to go about this is to focus on the character and competence of the company rather than on the product. Any company can offer you different options for materials or a good price, but a good company is going to cater to you and make sure they’re always doing everything right.

Make sure you also consider how you feel during your interactions with the roofing contractor. Do you feel heard and understood? Or do you feel like you’re being pressured into buying something you don’t want or need? There’s a big difference between those two conversations.

It’s also important to do some background research on each roofing contractor. Check out their websites, read their reviews on different platforms, and ask around your community to see if you know anyone who has worked with them.

Once you find a roofing company that you can trust, then the next step is to look at their proposal to see if it will work for you.

How do I know if a roofing contractor is reputable and qualified?

Now that you’ve read this article, you no longer need to feel stressed about finding the right proposal for you and your home. You know what a proposal should include and that it’s important for roofing contractors to explain pricing in the proposal because it demonstrates trustworthiness and investment in you.

You also know that a crucial step in comparing proposals is comparing the roofing contractors themselves to make sure that you’re choosing a reputable company that will provide you with a great quality roof.

The prices should all be fairly similar, so in the end, it comes down to choosing the roofing contractor that is invested in quality and transparency.

Frequently Asked Questions

1. What is the difference between a roofing estimate and a proposal?

Estimates and bids are non-binding "ballpark" figures that often lack detail. A proposal is a tailored document that includes a specific scope of work, total costs, and warranty details. Once signed, a proposal becomes a legally binding contract.

2. Why are some roofing bids so much lower than others?

Drastically low bids are usually a warning sign. The contractor may be using subcontractors to save on labor, skipping mandatory permits, or omitting specific line items like flashing or ridge vents that will be added as "surprises" later.

3. Should the proposal specify who is actually doing the work?

Yes. A transparent proposal should clarify if the company uses its own trained employees or hires subcontractors. Knowing who is on your roof is critical for accountability and safety.

4. What hidden fees should I look for in a proposal?

Ensure the proposal explicitly mentions permits, taxes, and disposal fees. Some contractors leave these out to make their initial price look lower, only to charge you for them after the work begins.

5. How do I know if a proposal is "generic" or tailored to me?

A tailored proposal should address specific issues found during your inspection, such as specialized skylight flashing, chimney repairs, or unique ventilation needs for your specific attic layout.

6. How do I decide between several companies that all have 5-star ratings?

When the ratings are equal, you must evaluate the company's technical competence and transparency. 

7. Are there common "fine print" items that I should worry about?

Always check for disclaimers that excuse the roofer from responsibility for property damage. A reputable contractor will stand behind their work and protect your siding, driveway, and landscaping.

8. Is the shingle brand the most important part of the proposal?

While material quality matters, the installation quality is more critical. Think of it like buying a car that arrives in pieces; who puts it together matters more than the brand of the parts.

9. What should I know about roofing before I even meet with a contractor?

Being prepared helps you spot red flags early. Check out our guide on what to know about roofing before meeting with a roofer.

10. How can I verify if a contractor is actually qualified?
