Knowing how to estimate a roofing job goes a long way when bidding projects and making profits in the roofing industry. If you don’t know what goes into an estimate or bid, chances are you end up undervaluing your services and finishing a job without making significant profits.

Thanks to technology, estimating a roofing job nowadays isn’t as difficult as it used to be. It can even be done now without having to be onsite and physically measuring the roof with a good, old measuring tools.


Here are some tips on how to properly price a roofing job even when you’re miles away from the project.


How to Estimate a Roofing Job: 3 Tips for a Winning Bid


1. Use digital tools

Gone are the days when roofing companies have to be onsite just to get some estimates for the project. Technology has taken good care of that and there are now tons of amazing tools that can get the job done for you quickly and accurately, even from afar. 


Since these tools can accomplish virtual measurements of a roof and give you estimates of the labor and material costs, they effectively save you precious time and reduce your exposure to health risks. Here are some tools worth checking out:


  • Hover – creates a 3D model out of photos snapped through the app
  • EagleView – provides an aerial view of the house and calculates estimates for roofing and siding jobs depending on your high-end and low-end estimates
  • iRoofing – an all-in-one software integrating top measurement platforms to generate estimates, create visuals, make digital contracts, and provide financing options
  • Roofscope – a tool that employs aerial technology to measure and estimate not only roofing jobs, but also gutters, sidings, and more


2. Check all estimated costs

In one of his articles for Roofing Contractor, Monroe Porter notes that “90% of roofers underbid the job” and thus undercut their profits. How does this happen? Most roofers underestimate their overhead costs, pricing the job by the number of squares instead of by the time it takes to complete it. Some roofers also rely on templated roof estimates which can sometimes miss essential costs that could mean the difference between making a profit and breaking even.


To avoid underbidding and to ensure you get good profits from a job well done, take the time to review the cost estimates yielded by your tools or templates. Check the following:


  • Accurate roof measurements
  • Material cost
  • Labor cost
  • Overhead cost
  • Mark-up for your target profit


3. Add some visuals.

It’s a little difficult for homeowners to greenlight a project they don’t see. Hence, when you’re estimating a roofing job, consider creating virtual mock-ups of what their home would look like when a particular roofing style is used or when different windows, doors, or siding styles are added.

Adding some visuals allows potential clients to get a good idea of what you’re proposing in your bid. This is crucial because when clients don’t understand the value you bring or what exactly you’re charging them for, they tend to haggle the bid down or go to another roofing company. Use visuals to show them that your bid is reasonable and the work you’d do offers the best value for their money.
