What to Consider When Requesting a Flat Roofing Estimate

The estimate is a crucial part of any flat roofing installation. It not only helps you understand what you should expect but how to best budget for the project.

That’s why your flat roofing contractor should consider certain key elements to prepare a thorough estimate. That’s whether you’re installing a new commercial roof or a flat roof replacement for your residential building.

Since your roof is a substantial investment, you should know what a comprehensive estimate looks like and what points it should cover. If you find even a single point missing, make sure you consult your contractor.

In this post, we compile all the important information you should find in a flat roofing estimate.

What’s Involved In a Roofing Estimate?

A roof is a significant investment which, to make the most of it, requires you take every step carefully. And the first is to scrutinize your quote. Here’s what’s involved in a roofing estimate.

Contact Information

Make sure all the company’s contact information is included: name, address, phone number, and email. Also, their licenses and insurance details should be there to ensure their legitimacy. If the contractor is unable or unwilling to provide that information, don’t hire them.

Labour and Material Costs

The estimate should break down the cost of:

  • Labour
  • Flat roof materials (including roof covering, flashing, shingles, underlayment, new ventilation, gutters and sealant)
  • Removing the previous roof, as well as the cleanup and disposal of construction debris
  • Equipment
  • Local permits

Project Timeline

The project’s timeline should meet your needs and schedule, so make sure the estimate includes the start and completion dates. Although the completion date is only approximate, it gives you an idea of how fast the contractor will finish the job.

Detailed Description of the Job

This quintessential part of your roofing quote clearly mentions the names and responsibilities of the contractors and the type of work being done.


The warranties covering your contractor’s products and workmanship are a significant part of your estimate; these should be clearly stated.

They should also include any penalties the contractor will incur if they fail to honour the contract. This determines who is accountable if a problem arises after the project’s completion and whether future repairs or replacements are in line with the warranty’s terms and conditions.

Additional Costs

No one likes hidden charges, which is why your roofing estimate should outline any additional costs. These can include special customer requests or unexpected delays in the project’s completion due to weather, manufacturing or supply issues, or sudden order changes.

Payment Information

All roofing quotes must include the payment method, any down payments or progress payments, the final payment’s due date, and penalties for failed or late payments. Including these items helps avoid misunderstandings and ensures an uneventful flat roof installation. Most roofing contractors require a 30% down payment. It’s advisable to be clear on this point and avoid making the final payment in advance in order to have the project finished to your satisfaction.

Termination Clause

Another key item of the estimate is the termination clause. This sets out the events upon which one or both of the parties can terminate their contractual relationship. This makes it convenient for both customers and the roofing contractor to establish a way to calculate how much the cancelling party owes the other. It also limits the former’s liability.

Additional Tips to Finalize Your Flat Roof Installation

Once you’ve received a quote that addresses the essentials outlined above (but before the contractor starts work), here are a few other things you should consider.

  • Does the quote include tax? If not, request one that does and then re-evaluate it based on your budget.
  • Never sign a contract with a roofing contractor who has never performed a roof inspection.
  • No matter how fair the quote seems, always check the company’s references before making your final decision. Ask for at least three references and contact them all.
  • Make sure every detail, proposal and estimated cost is put down in writing. This helps reduce miscommunication and confusion which can delay the installation of your flat roof.
  • Always choose the contractor who provides free quotes.
  • Ask the contractor what they’ll do if they find more damage when working on the roof than they noticed during the inspection.
  • Ask about their safety record.
  • If you have questions about the termination clause and/or warranty, ask. Any confusion can lead to costly mistakes.


The estimate is a crucial aspect of any flat roof installation. In the absence of a well-calculated quote, you could end up with a roofing company that compromises the durability and appearance of your residential or commercial property. A proper quote not only fosters clear communication between you and the contractor but helps avoid unnecessary expenses. So, the next time you request a quote from a roofing contractor, make sure it includes all the above-listed points.
