Shingle Roof Installation Guide

Although your roof may not be front-and-center on your list of home improvement and maintenance projects, you can’t afford to forget your roof. Shingles will experience significant wear and tear throughout the year, withstanding whatever abuse nature sends your way.


Explore the details about asphalt shingle roofing by visiting the Coon Rapids, Minnesota website. You’ll get all the pertinent facts about preparing the surface, choosing an underlayment material, adding ventilation and applying the singles. Whether you plan to shingle your own roof or you decide to hire an expert, you’ll have the information you need to proceed with the project.


With a complete home guide to shingle roofing, you’ll be ready to install and maintain your roofing materials to keep your roof in satisfactory condition.

    Although a new roof is generally a significant expense, ignoring your roof could result in major structural damage to your home.
  1. 1.Preparing Your Roof

    Before you begin a roofing project, check with local municipalities to see what type of building permit you need to purchase. Local officials may require a site inspection and verification that you’re installing a roof that adheres to codes. You’ll also need to find out whether your local area allows layover reroofing or whether you’ll need to tear off the current roof and install a new roof directly onto the underlayment.

  2. 2.Underlayment Layer

    Your local municipality will also stipulate what type of underlayment needs to go onto your roof first. This will typically include eave flashing, bitumen sheets and layers of felt. Generally, after removing the current roof, you’ll need to start over with a fresh underlayment layer also to prepare for the new roofing materials.

  3. 3.Roof Ventilation

    To eliminate extreme temperatures from developing in your attic, as well as potential moisture problems, roof vents need to sit on the surface of your roof. The recommendations for ventilation are one square foot of ventilation for every 300 square feet of attic space under your roof. It’s important to spread out the vents evenly for effective results.

  5. 4.Installing the Roof

    If you’re installing your own roof, you’ll find specific installation instructions for your roofing materials. The specifications will include a minimum number of fasteners per shingle or shingle strip. It’s important that the fasteners you choose are galvanized or stainless steel, copper or aluminum to prevent rust. The nails also need to be a minimum size so they penetrate completely into the roof sheathing.


    Where your roof surface intersects with a different slope or direction and everywhere there are roof openings over the surface of your roof (chimneys, vents, etc.), you’ll need to install corrosion-resistant flashing to prevent leaks.

  6. 5.Final Inspection

    After your new roof is up and you’ve completed the work, you may need to have your local municipality come back and conduct a final inspection to make sure that your roof meets all code and building requirements.


    Although a new roof is generally a significant expense, ignoring your roof could result in major structural damage to your home. Pay attention to the condition of your roof so you will notice wear and problems before they develop into major issues. Your new roof should provide years of protection from the elements to keep you and your family comfortable.
