Why Choose Asphalt Shingles?

Asphalt shingles remain one of the most popular roofing materials for residential and commercial properties due to their affordability, versatility, and reliability. Available in a wide variety of colors and styles, asphalt shingles can complement any architectural design while providing excellent protection against Michigan’s variable weather conditions.


A new roof offers enhanced durability against wind, rain, snow, and hail, preventing leaks and structural damage.

Signs Your Roof Needs Replacement

Knowing when it's time to replace your asphalt shingle roof can save you from expensive repairs and damage. Watch for these common indicators:

  • Age of the Roof: Asphalt roofs generally last 20-30 years. If yours is approaching or surpassing this, replacement should be considered.
  • Missing or Curling Shingles: Shingles that are cracked, missing, curling, or buckling reduce your roof’s effectiveness and indicate wear.
  • Granule Loss: Excessive granules in gutters or downspouts signal that shingles are deteriorating.
  • Water Leaks or Stains: Interior ceiling stains or water leaks mean your roof’s protective barrier might be compromised.
  • Visible Sagging: A sagging roof deck can be a sign of structural issues requiring immediate attention.

Our Asphalt Shingle Replacement & Installation Process

Our team follows a thorough, step-by-step process to ensure your new asphalt shingle roof performs flawlessly for decades:

We assess your existing roof's condition and discuss your preferences, budget, and timeline.

Leveraging our CertainTeed and GAF certifications, we help you select durable shingles that fit your style and needs.

We carefully remove the old roofing materials, inspect the underlying structure, and make necessary repairs.

Our certified installers apply new underlayment, flashing, and shingles following manufacturer guidelines and industry best practices.

We perform a detailed quality check and leave your property clean and free of debris.


  • How long does an asphalt shingle roof replacement typically take?

    The timeline depends on the size and complexity of your roof but generally takes between 1 and 3 days for most residential properties. Our team will provide an estimated schedule during your consultation.

  • What warranties come with a new asphalt shingle roof?

    Because we are certified CertainTeed and GAF installers, your new roof installation can qualify for manufacturer warranties ranging from 20 years to lifetime coverage, depending on the specific shingles selected. We will review all warranty details with you prior to installation.

  • Can you install asphalt shingles over my existing roof?

    In some cases, it is possible to install new shingles over an existing layer, but this is not always recommended as it can affect ventilation and roof weight. Our team will inspect your roof and advise on the best approach for long-term durability and performance.

  • How do I maintain my new asphalt shingle roof?

    Regular inspections, clearing debris from gutters, and prompt repairs of any minor damage can extend the life of your roof. We also recommend scheduling professional inspections every few years to catch potential issues early.
