The first step in the Mike Hansen Roofing Company Process is handling your estimate request. Whether you call in and speak to one of our live secretaries or submit an online estimate request form, we will be able to provide you with a free estimate handled by one of our roofing professionals.


Once a roofing professional has come out, you will receive a proposal for the work that we are able to perform. We will provide you with two copies of the contract, one for you to keep for your records and a second for you to sign and return to your estimator or Mike Hansen Roofing and Construction, 1400 Lake St., North Mankato, MN 56003. Once we have received the signed contract your job goes directly into the scheduling department to be set up for completion.


The third step in the Mike Hansen Roofing and Construction,Company Process is to prepare for the work to begin. We will select the best crew for your project, and a pick the best time for the work to begin (weather and your schedule permitting) and in agreement to your schedule. Once we are ready to begin the job, we will order any material that is needed, and have it delivered, or brought to the job site by the roofers themselves.


When the crew arrives, they will begin setting up everything needed to complete your job. This may include tarps, ladders, plywood, extension cords, etc. If there are any questions that you would like to ask during any part of this process, please give us a call. It is always best to inform us of any concerns as soon as possible so we can address them.


Removing an existing roof can be a loud and dangerous process. There is a lot of weight coming off of your home, about 10,000 lbs. on average. All of this material has to come off and is placed either directly into the equiptor (see our home page for the new roof, no mess process) or on the ground and removed by hand. It is important to understand that we do this every day, and that many homeowners only have a roof done once or twice in their lives. So again, if there are any questions or concerns please give us a call and we will be able to answer any questions you may have.


During the tear off process is the first time where the original roof deck is exposed. This is the first time we are able to assess the type and amount of wood that should be replaced. Many homes require little to no new wood, while others could need large sections replaced;, as it is about 10% of our customers need no new wood at all, 2% need a lot (over 400 feet), but the average runs 20-80ft.


With a solid deck to work with, we are ready to begin installing your roof system which consists of 4 parts.

  1. ICE BARRIER is installed at the eaves and in valleys of heated spaces. This is a self-sticking membrane, designed to resist melt water from entering the house if it backs up under the shingles when ice dams are occurring
  2. FELT PAPER, installed over the remaining exposed decking, was originally installed to protect the shingles from the sap in new roofing boards. Today its main function is to rei-enforce the shingles in situations of extreme windblown rain.
  3. SHINGLES At last! It's starting to look like a roof again. Anyone can claim to be a roofer, but few roofers have the hands on experience, installing hundreds of successful projects year in year out, with CertainTeed's ongoing training, support and inspection.
  4. DETAILS - vents, chimney flashings, pipe flashings... when inexperienced roofers have problems it is usually here. For us there is no such thing as 99%, we feel 1 that one drip is 100% failure. Our crews take pride in building a roof system that not only looks great but will provide years of worry- free service.


Once everything has been completed, we will sweep and haul away all of the debris around the house. At that time, we hope you will fill out our Quality Evaluation Form.
