Roofing Cost Estimator Breakdown

A roofing cost estimator or calculator is not very well suited for the average homeowner. Odds are, you are looking for the best way to calculate the estimates for roof costs. Many roof replacement calculators out in the internet space compile confusing metrics using square footage, dimensions, and other bits of information that are hard to determine. While it does its job in helping you understand what goes into roofs, it does not accurately show you how to estimate the cost of your roof. Here is one example!

Roof length (eave side):  # ft.
Roof width (gable side): # ft.
Roof Slope:1-24 (flat – steep slope)
Roof Difficulty:Simple roof, Medium difficulty, Very cut-up roof
Roof Tear-off:YES or NO
Number of floors:Single-Story, Two levels, Three levels
Number of Sky-lights:Enter # here
Number of Chimneys:# of Chimneys
Ridge vent: # ft.
Roofing material:Asphalt, Cement, Cedar, Stone Metal, Metal, etc

Frankly, no one has the time or resources to climb onto their roof and measure their ridge vents, eave length/widths, or their roof tear-offs. With that said, the vast majority of people often leave the roofing cost estimator with more questions than answers. 

 Rather than plugging in random numbers and hoping for accuracy, the best thing to do is to have a contractor manually come and inspect the home. Doing so will put a face to the price you are given and can help determine whether or not they can or cannot be trusted. The team here at Roof-Life is acutely aware of how confusing and stressful roof replacement estimation can be, which is why we offer Free Roof Inspections

 If you’re looking for an accurate report of how much a roof replacement will cost, here are a few things you should consider.

Things to Consider


  • Ensuring that the contractor you’re hiring has legitimate credentials is a crucial first step. 
  • Important to not be swayed by the low-ball prices offered by freelancers with fake or no credentials.

Questions to ask:

  • How long have you been in business?
  • Do you have a social media page?
  • May I see your qualifications?
  • Have you had similar situations to this? I’d like to hear about it.

 These questions may seem invasive to some. However, any professional contractor should be more than ready, willing, and able to provide any information the client deems necessary. Understand that your potential contractors are there to service YOU. You hold the buying power for their services. 

 When looking for legitimate credentials, be sure to research roofing credentials for your local municipality.

  • Roofing insurance is a type of liability insurance. It is responsible for covering any damages that are made by the client or passers-by.
  • Roofers are exposed to dangerous working conditions like a collapsing roof, falls, and personal injuries while fitting a roof. Because of this, roofers can claim liability from their customers since it occurred on their property. Insurance protects homeowners and businesses from facing liability.
  • On the other hand, it’s also possible for roofers to damage their customer’s property while working. In essence, the customer doesn’t have to pay more out of pocket for damage caused by the roofer. The roofer must also provide proof of workman’s compensation insurance as well.

Questions to Ask:

  • Does your company offer liability insurance? If so, how much?
  • Have there been any recent injuries or damages to property while you have worked?
  • What does liability insurance cover?

  Getting to know how your hired contractor or company’s work history can provide insight into work history. Knowing this information serves two purposes. It can demonstrate the integrity of the people you have hired, and it can help establish a sense of trust in who you have hired. 

Length of Business

  • Asking how long the company has been in business ensures that your roof is in the hands of knowledgeable and experienced people.
  • Roof-Life has been working for the Portland area for over 30 years.

Questions to Ask:

  • How long have you been in business?
  • How long have you personally worked on roofs?

Is Work Subcontracted?

  • Subcontracted work often means degraded quality and an overall lack of care for the work being done.
  • Subcontracted work may also bring on workers who are not experienced in roofing. These workers may hold a general specialization in construction work. 

Questions to Ask:

  • Are the contractors working on my roof coming directly from your company or a third party?
  • Will any part of the work require you to hire a third-party company?

Roof replacement is an expensive endeavor. As a homeowner, you have every right to know for the things you are paying for. It is the roofer’s unspoken responsibility to be as transparent as possible about all material costs and fees. There have been instances where homeowners to new roofs incurred hidden fees and charges that they were not aware of. A pillar to customer loyalty and satisfaction is transparency.


Before the work can begin, it will help to ask your contractor the options available and the grade of quality. The contractor should have sufficient knowledge in all manner of roofing material, how it’s made, and what it is good for. Being transparent about how the material holds up in certain conditions is important as well.

Roof Warranty

What is The Warranty on the New Roof?

  • Most companies only offer 1-year to 3-year warranties. This is not a sufficient warranty timeline as most roof major problems usually appear 4-5 years after the roof is installed. This is one of the ways most companies avoid having to reimburse their clients and fix problems that should never have happened in the first place. Roof Life of Oregon offers a lifetime workmanship warranty as long as they own the home and transferable to the next owner. For more information on our Workmanship Warranty, click here!
