What Goes Into a Roofing Estimate?

What Goes Into a Roofing Estimate?


When it comes to replacing or repairing your roof, one of the most crucial steps is obtaining a roofing estimate. A comprehensive roofing estimate not only provides you with an overview of the project's costs, but also allows you to understand the various components involved in the process. 


Roofing estimates vary from contractor to contractor, and this can make them difficult to compare. An estimate should be as detailed as possible and include a list of materials, labor costs, and any additional expenses. Here’s a look at everything you should look for in a roofing proposal and what you should expect from a trusted roofing contractor. 

Before the Estimate: A Thorough Roof Inspection

In order to create an accurate cost estimate to repair or replace a roof, it’s important for the contractor to perform a close inspection of the roof and the surrounding structures. This includes viewing and assessing: 


  • The condition of shingles
  • Any weak areas in the decking
  • Deterioration of gutters
  • Damaged flashing around chimneys, walls, or other structures
  • Moss, algae, or mold growth on the roof or decking
  • The quality and condition of the ventilation system
  • Attic spaces where mold growth or moisture damage has occurred


To repair or replace a roof effectively, any problems in these areas will need to be addressed and can add to the cost of the estimate. 


Honest Abe Roofing offers a free roof inspection that checks for these potential issues—and more—with a 16-point checklist. A thorough inspection prior to generating an estimate can help homeowners avoid additional surprise costs when the project gets underway. 

Roofing Estimates: What to Expect

After the inspection, the roofing contractor will generate an estimate of the total cost of the project. A complete estimate will include line items for everything from the cost of roofing materials and labor to fees for disposing of the old material that is removed. Any estimate should include the items below. 


Cost of Roofing Materials

The factor that has the greatest effect on the overall cost of a roofing project is usually the choice of materials. Different types of roofing materials have varying price points, durability, and aesthetic appeal. Here are a few commonly used roofing materials and their estimated costs:


  • Asphalt shingles: Widely used and cost-effective, asphalt shingles are a popular choice for homeowners. They typically range from $100 to $200 per square (a square refers to 100 square feet of roof area).
  • Metal roofs: Known for their longevity and durability, metal roofs come in various styles and materials such as steel, aluminum, and copper. The cost of metal roofing can range from $200 to $1,000 per square, depending on the type and quality of the metal.
  • Tile roofs: Tile roofs can be made of clay, concrete, or slate and are often chosen for their curb appeal and durability. Tile roofs last the longest compared to other options. This material is popular in warm climates, as the tiles help to reflect heat. Tile roofs are the most expensive option, typically ranging from $800 to $2,500 per square.


Roofing Components

Besides the main roofing material, several components contribute to the overall stability, durability, and performance of your roof. These components are essential for ensuring proper installation and protection against the elements and should be included in any roofing estimate: 


  • Drip edge: A drip edge is a strip of metal installed along the edge of the roof that helps control the flow of water to prevent it from getting under the shingles, where it can cause water damage. The cost of drip edge installation can range from $1.50 to $3 per linear foot.
  • Underlayment: Serving as a moisture barrier, underlayment is a crucial layer installed between the decking and shingles. Underlayment is usually made of felt or a synthetic material. The estimated cost for underlayment ranges from $0.15 to $0.50 per square foot.
  • Flashing: Flashing helps prevent water penetration around roof features such as chimneys, skylights, and vents. Depending on the materials used, flashing costs about $10 to $20 per linear foot.
  • Ventilation: Proper ventilation is essential for maintaining a healthy and energy-efficient roof. It helps regulate temperature, reduce moisture buildup, and prevent mold growth. Costs for installing vents or ridge vents vary, but the estimated range is $300 to $600 per vent.


Labor Costs 

Labor costs constitute a significant portion of a roofing estimate. They include expenses associated with hiring professional roofers and the time required to complete the project. The complexity of the job, the size of the roof, and the accessibility of the site are factors that affect the total labor cost. 


The pitch of the roof can also be a factor. Steeper roofs require more safety precautions and may take longer to install, and this can affect labor costs. 

On average, labor costs can range from $3 to $7 per square foot.


Clean-up and Disposal

For a roof repair or replacement project, fees for removing and disposing of the old materials should be factored into the estimate. This expense can vary depending on the weight and type of roofing material being removed.


Permits and Inspections

Local regulations may require the roofing contractor to obtain permits and schedule inspections during the roofing process. The roofing estimate should include any associated permit fees and inspection costs.

Why a Quote From Honest Abe is Better Than An Estimate

While a roofing estimate is roughly how much a contractor thinks the job will cost, that price isn’t set in stone. If a roofing company gives you an estimate and then finds a big issue during installation, they may tack on extra fees. 


When you work with Honest Abe Roofing, you get a solid quote – a No-Risk Guarantee – before we even begin the project. This means the price you are given is the price that you will pay, guaranteed.  Though our 16-point inspections help identify most issues, sometimes a problem is discovered once the old roofing materials are removed completely. After the project is started, if we determine that additional work is needed that was not listed on the contract, we will complete that work at no additional charge. 


At Honest Abe Roofing we pride ourselves on being an honest roofing contractor. We understand that you budget for a home improvement project based on the numbers given to you by contractors, and we believe that those numbers should be honored.
