Repeatedly underestimating bids might destroy your roofing company. You want to provide accurate roofing estimates and generate money.


Underbidding a roofing work might cost you money and confidence. Your consumers need to trust the roof repair or replacement cost.


Stop underbidding and start making your hard-earned profit with these roofing job pricing tips.

1. Talk to Homeowner


Before quoting, meet with the customer. Prepare to ask the client:


  • What is your budget?
  • Which roof do you want?
  • What's your house like?
  • Do you have solar panels or satellites on your roof?


2. Roof Check


Naturally, inspect the roof. Check the roof for damage or features that may increase expenses.


We encourage photographing concerns to avoid future troubles. Show your client and save the photos to their contact card.


3. Roof Measurement


After photos and inspection:


  • Measure the roof.
  • Measure the roof to determine how many roofing squares you need.
  • Make sure these figures are precise, as roofing materials make up most of the cost.
  • Calculate roof base length, breadth, pitch, and roof squares. EagleView can measure for you without mental calculation. You may also use the roofing calculator to help you acquire accurate roof estimates step-by-step.


4. Estimate Roofing Material, Labor, and Overhead


Costing Materials


After defining the roofing task, you must choose materials and estimate costs. Depending on your source, asphalt shingle roofs might cost $7.00 per square foot.


The rambler owners want $4.50-per-square-foot asphalt shingles.


$4.50 per square foot x 100 square feet each square = $450 per square


$15 squares x $450 = $6,750


Also, pay attention to other roofing expenditures, like nails, vents, flashing, tools, underlayment, and more. This roofing work needs $650 for those goods.


$7,400 = $6,750 shingles + $650 supplies


Costing Labor


Next, calculate labor expenses. Multiply your project's hours by your workforce. You can estimate the time if you've recorded labor hours for past tasks in your CRM.


Your 4:12 roofing job may take two roofers 30 hours.


2 employees x 30 = 60 labor hours


Then multiply those work hours by your employees' hourly rate to obtain a total labor cost. We'll utilize Salary.com's $18-per-hour roofer example.


60 work hours x $18 pay = $1,080


Overhead Calculation


After labor expenses, consider overhead. Roofing prices must compensate for these expenditures. Use an overhead cost calculator for this.


We'll assume a $2,800 monthly overhead. Then we'll use that amount to compute your overhead expenditures for a week. Divide monthly costs by four, as most months have four weeks.


$2,800 per month / 4 weeks = $700 weekly overhead


Divide your weekly overhead expenditures by your weekly work hours to get your hourly rate.


Say you work five nine-hour days a week, totaling 45 labor hours.


$700 weekly overhead/45 weekly labor hours = $15.56 hourly overhead cost


Multiply the hourly overhead cost by the job's labor hours.


$15.56 hourly overhead x 60 work hours Equals $933.60 in job overhead.


Finally, add material, labor, and overhead charges to calculate the roofing project cost.


Material cost: $7,400


Labor cost: $1,080


Overhead cost: $933.60


Total cost: $9,413.60

5. Markup


It would help if you marked up the roofing job's breakeven cost to make a profit. Your roofing project markup should be more than your profit margin %.


To calculate project markup, divide project profit by profit cost and multiply by 100.


Markup=(Profit/Cost) x 100


Profit margin is net income divided by net sales. Multiply by 100.


Profit Margin = (Net Income/Net Sales) x 100


Markup the rambler roofing work by 5% for a 7.6% profit margin. This work would markup $769.30.


$10,182.90 = $9,413.60 + $769.30 markup.
