What's Included in a Roofing Estimate?

March 21, 2023

Exploring options for your roof replacement can be a daunting task, particularly when you begin receiving numerous quotes.

What should be included? What should be excluded? Does it address all of your roofing requirements?

Many homeowners are unsure about what to look for in their roof estimates or whether they're being exploited. As it is vital to comprehend the contents of your estimate during the replacement process, we will clarify and simplify it for you.

Your quote should to be highly detailed, providing a thorough breakdown of all tasks to be completed during your roof replacement. This list should include the number of roof layers to be removed, the measures taken by the contractor to safeguard your property, and various other aspects.

Upon finishing this article, you will be well-equipped to identify essential elements when discussing the proposal with your contractor.

Incorporating Labor Costs into Your Roof Estimate

Labor is incorporated into each element of your estimate. For instance, the shingle cost in your quote comprises both the material expense and the installation labor charges.

While labor costs may vary among contractors, material prices tend to remain consistent within a specific region.

Number of Layers to Be Removed from Your Existing Roof

An essential item on your roof replacement estimate should be the number of layers the contractor plans to remove from your old roof. Be aware that if the estimate only includes one layer but two layers need removal, the final cost will exceed the initial quote.

This discrepancy may occur if the contractor failed to check for multiple layers or aimed to present a lower cost to outbid competitors. To avoid such issues, it is imperative to engage a trustworthy local contractor for your roof replacement.

Measures Taken by Your Contractor to Safeguard Your Property During Roof Replacement

A crucial responsibility of your contractor is to ensure your property's safety. The roof estimate should contain a detailed list of materials and expenses associated with property protection measures.

For instance, the roofing contractor should mention the costs of covering items in your attic, protecting your home's landscaping and vegetation, and if applicable, shielding your swimming pool with a brand-new tarp directly from its packaging.

Methods for Installing Your New Roof

The estimate should include the installation technique, the quantity of nails, and the number of nails employed per shingle. If your contractor does not provide hand nailing as an option, the estimate may not include a line item for the installation method.

In the absence of a specified method in your estimate, it is reasonable to assume that your roof will be installed using the air nailing technique.

Addressing Rotten Decking Replacement Needs

Since your roof's decking is only visible after removing the old one, the estimate should include an item detailing the cost per sheet for replacement in case rotten decking is discovered. Some contractors incorporate decking replacement into their quotes by default.

In such cases, you will be charged for decking materials regardless of whether they are used or not. Make sure to discuss with your contractor how they intend to address rotten decking when reviewing the proposal together.

Drip edge

The roof estimate should specify if a drip edge installation is required for the rakes (the sloping edge of a roof at the house's end wall) and eaves (the lower edge of a roof that extends beyond the house's edge).

In some cases, a drip edge may not be necessary around the rakes, but it is essential for the eaves near the gutter. The roof replacement estimate should outline the color (if important to you), the amount, and the locations where the drip edge needs to be installed.

Roofing System Components

Your roof replacement estimate should feature a detailed list of the components within the roofing system that are due for replacement.

The following are the five primary components that ought to be covered in your estimate:

  • Underlayment: This felt material is placed over the decking for added protection. The estimate should specify the size, type, and manufacturer of the underlayment to be used.
  • Ice and water shield: A waterproof membrane that safeguards roof valleys from ice and water damage. The estimate should detail the specific material intended for waterproofing the valleys.
  • Starter shingles: Asphalt-based shingles that waterproof eaves and rakes. The estimate should mention the manufacturer and indicate if they will be installed on both the rakes and eaves.
  • Shingles: The outermost layer of your roof, visible from the exterior. The estimate should cover the style, color, and manufacturer of the shingles selected for your roof replacement.
  • Ridge capping: Trim installed at the peak where two roof slopes converge. The estimate should specify the manufacturer and material to be used for the ridge capping.

Exercise caution, as many roofing contractors may reduce costs by utilizing standard three-tab shingles, cutting them, and repurposing them for ridge capping and starter shingles. If these components don't come from a particular manufacturer, your estimate might not have separate line items for starter shingles or ridge capping.

Selecting the Appropriate Roof Vent Type

Ventilation systems can be classified into two categories: active and passive. Active ventilation involves drawing air from the exterior and expelling it from the interior. Passive ventilation relies on natural forces, such as wind, to circulate air in the attic.

Once you have decided on the ventilation system, you will need to select the style of vent visible on your roof. The available vent options include:

Active:

  • Turbine vents
  • Power vents
  • Ridge vents equipped with a baffle
  • Solar-powered vents

Passive:

  • Static or box vents
  • Ridge vents without a baffle
  • Gable end vents

Your roof replacement estimate should include the style, color, and quantity of vents required for your roof.

Roof Flashing and Pipe Boots

To prevent leaks from roof pipes, contractors usually install a neoprene boot (pipe boot) at the penetration's base. Your roof estimate should specify the number of penetrations and the particular type of boot required for each.

The estimate should also outline any necessary roof flashing. Flashing is a metal component placed wherever shingles intersect with another surface, such as a wall, chimney, or open valleys.

If the metal is in good condition, your existing flashing may be reused to reduce the cost. The estimate should indicate where the flashing will be installed and the metal type to be used.

Clean-Up and Dumping Fees

The tear-off process during a roof replacement generates significant amounts of debris. The contractor will load this debris onto a dump truck and transport it to a landfill.

Your roof estimate should cover not just the labor involved but also the expense of dumping the debris at the landfill. The same principle applies to the labor needed for post-replacement clean-up.

The time and labor required for collecting nails and any missed roofing debris to guarantee a pristine property should be included in every roofing estimate.

Warranty

It is crucial to understand your warranty options when investing in a roof replacement. Your estimate should outline the type of warranties included with your roof replacement.

It should specify the material warranties you will receive. For instance, if your new roof is registered with a manufacturer, you may qualify for an enhanced warranty.

Furthermore, your estimate should indicate the duration of the workmanship warranty offered by the contractor, as it may vary between contractors.

Validity of the Roof Estimate

As soon as your contractor provides you with the estimate, the countdown begins. Your estimate should specify the period during which the offer is valid.

Due to the fluctuation of roofing material prices, most proposals are valid for 90 days. If you intend to sign the proposal after the 90-day window, the estimate will be revised to reflect the new material prices.

Your Right to Cancel the Contract

Your estimate should include a provision for the right to cancel the contract, allowing you to withdraw from using a particular contractor. By law, you have three days after signing to cancel the contract if you feel pressured into signing or if you learn something that alters your decision.

Always carefully review the terms and conditions of your estimate. Some contractors may include a clause indicating that if you try to withdraw after the three-day right of rescission, you will be responsible for paying 10% of the total contract.

Reviewing Your Roof Replacement Estimate

The critical step in obtaining a roof replacement estimate is reviewing it with your contractor. Your contractor should schedule a meeting to discuss each item in your proposal with you.

It is essential to have a detailed estimate, allowing you to understand precisely why your roof replacement costs what it does. Asking the right questions during your meeting with a potential roofing contractor is essential.

Hiring the wrong contractor may result in a negative experience and expensive problems. After investing in a new roof, no one wants to be in a stressful situation or spend more money.
