We worked with Aron and he was fantastic. Quick to respond to any questions and worked hard to find the supplies we needed when they were scarce.

Roof Installation or Replacement

We had a great experience with Grieman Construction. Aaron made the effort to connect with us right away and came to our house to discuss the quote, even before we signed the contract. He also worked extensively with our insurance and went above and beyond to negotiate what the insurance was willing to pay (and insurance was less than helpful). We received frequent updates about the timeline of the roof installation, and more than once Aaron let us call him on weekends and evenings to sort out the details. The roof was installed well by the team and looks amazing. We were impressed from start to finish.

Details: Full replacement of existing roof • Roof is leaking or has water damage • Two-story building • All steep and difficult to navigate • 1,000 - 2,000 sq ft • 11 - 20 years old • Asphalt shingles • Yes, insurance claim has already been approved • Residential

Greiman did a great job with our roof - did the job quickly, cleaned up thoroughly, and even worked with our insurance adjuster. Everything was done just the way they said it would be. Couldn't be happier!

Hire them! Very prompt with the estimate with high quality GAF materials. Aaron and his crew were very professional. The crew accomplished the roofing job in one day and it looks great. Very responsive to our special requests. We are very satisfied customers. Highly recommend this service.

Roof Installation or Replacement

I had a tight deadline and Greiman was able to accommodate my schedule and finished the job ahead of schedule. They were working through the weekend without any complaints or dip in quality. The whole process from start to finish was very smooth.

  • What should the customer know about your pricing (e.g., discounts, fees)?

    We are confident that our prices are competitive when comparing apples-to-apples. You might find a lower price, but you'll be hard-pressed to find the value that comes from a contractor that guarantees a dedicated field representative to manage your project for you, and that carries a premium factory certification requiring selective approval by GAF, the #1 manufacturer in the United States and Canada.

  • What is your typical process for working with a new customer?

    The first step for retail projects is usually to speak on the phone to confirm a few basic details about their roof and siding. We do not install three-tab shingles and are not currently installing metal roofs, and because warranties do not cover laying over existing shingles, every roof we install will involve tear-offs existing material. If the decking beneath the shingles is deteriorated to the point where it won't hold a nail, or if there are cedar shakes or gapped boards, then we will remove and replace with 1/2" OSB. Once we've spoken a bit, we schedule an appointment to discuss material options and to measure the home. If we are able to get out before the appointment to measure, then an estimate can usually be provided during the appointment. Otherwise, it takes between 24-48 hours to work up an estimate. We cannot provide a quote until measurements are completed by our field representative. Insurance work is something that we specialize in around our home office, and hope to establish that same reputation in the Cedar Rapids Corridor. We ask for a copy of the scope or estimate that your insurance adjuster will provide. Some insurance companies will try to get you to collect competing bids, so they can keep as much of your premiums as possible. You cost should be limited to your deductible, and is already taken out of insurance's initial check to you. Our field representatives are available to discuss any questions or concerns you might have about the process, materials, timeline, or financing.

  • What education and/or training do you have that relates to your work?

    Every field representative and installation crew must complete annual training from GAF in order to offer our excellent warranties.
