Sentry’s Transparent Estimating Process

Everyone wants to save money. But when it comes to repairing or replacing your roof, it is not wise to simply go with the lowest estimate.


At Sentry Roofing, we focus on VALUE.
Our Transparent Estimating puts everything upfront with
no hidden costs or buried fees so that you can compare, budget and plan with confidence.

  • Our professional Estimator comes to your house at a convenient time for you.
  • He will ask you questions that will help him more precisely diagnose problems.
  • He will actually climb on your roof for an up close inspection. We find that a close examination can reveal many problems that aren’t visible from a ground-level view.
  • We will produce an estimate report that is detailed but straightforward, so that you know what you are buying up front. There are no hidden costs.
  • We will gladly explain everything in your estimate so you can compare our value to any competitors you may be considering.

Our pricing is competitive, but not cut-rate.

  • We are not the cheapest because we believe that a cheap roof will not serve you well.
  • We are not the most expensive, because our system lets us do superior work at a lower cost than many more expensive contractors.
  • We challenge you to compare. You will not find any roofing contractor that will give you as much value for your money as Sentry Roofing.
