Key Takeaways

  • Recognizing when to replace your roof is crucial: in Michigan’s climate, many asphalt roofs reach the end of their lifespan around 20–30 years. This Old House
  • Choosing the right materials and certified contractors’ matters. Using premium brands like GAF or CertainTeed and working with a roofing specialist ensures better warranties and job quality.
  • Budgeting & financing are part of the process — an average asphalt shingle roof replacement can cost around $15,000, and many roofing companies offer financing options. GAF
  • Inspection, preparation, installation, and follow-up are distinct phases; each deserves attention to get the best result for your home.
  • Local conditions in Michigan — like freeze-thaw cycles, ice dams, and snow loads affect the process and material choices, so you need a roofer familiar with regional specifics.

When you live in Michigan, whether in Saginaw, Midland, Bay City, Traverse City, or Harbor Springs, the roof over your home takes a beating. From heavy snowfall and ice dams in winter to spring storms and summer sun, your roof system is working year-round. If you’re asking yourself, “Is it time for a roof replacement?” or “What’s involved in replacing a roof in a Michigan home?”, you’re in the right place.

In this guide, we’ll walk you through the entire process of a roof replacement: what to look for, how to choose materials (especially asphalt shingles from GAF, CertainTeed, etc.), how to select a local roofing company, what the budget and financing options look like, and how to maintain the results.

What is a Roof Replacement?

Roof Replacement

The process of removing an existing roof system (or necessary components) and installing a new roof system, including the deck, underlayment, flashing, ventilation, and final shingles (or other top-layer material).

Contrast with a roof repair, which addresses localized damage without replacing large portions of the system.

Why this matters: A complete roof replacement gives you a fresh start with new warranties and better longevity; a repair is often a stopgap.

Why Replace Your Roof? (Especially in Michigan)

Why now?

  1. Age and Lifespan: Most asphalt shingle roofs last about 20–30 years in average conditions. In Michigan’s harsher climate (cold winters, ice, snow), you might lean toward the shorter end of that spectrum.
  2. Visible Signs of Wear: According to manufacturers like GAF, signs like curling, missing shingles, granules in gutters, sagging, or light in the attic all point toward replacement rather than repair. GAF
  3. Protecting your Home: The roof is your home’s first line of defense against the weather. A failing roof leads to leaks, mold, and structural issues. Waiting too long can cost far more in damage than the replacement itself would cost.
  4. Added Home Value: A new roof pays off in curb appeal and resale value. One source estimates that a roof replacement added an average of $17,807 to resale value in 2023. GAF
  5. Warranties & Financing Opportunities: New roof systems often come with better warranties (especially when installed by certified contractors), and roof financing options are available. GAF
Pro Tip:

In Michigan, if your asphalt shingle roof is over 20 years old, has received little maintenance, or shows many signs of wear, start budgeting for a full replacement now rather than waiting until an emergency.

How to Prepare for Roof Replacement: Step-by-Step

Here’s the high-level flow for roof replacement. Each step will be broken down in depth below.

  1. Roof inspection & measurement
  2. Choosing materials and a contractor
  3. Budgeting & financing
  4. Scheduling and pre-installation preparation
  5. Installation day
  6. Post-installation inspection & warranty registration
  7. Maintenance plan

Roof Inspection & Measurement

Question: How do I know what condition my roof is in and what size it will be?

When you’re replacing a roof, the first step is to schedule a full roof inspection with a professional roofer (local to Michigan). During the inspection, they will look for:

  • Missing, curled, or cracked shingles
  • Granules in gutters
  • Sagging roof deck or visible daylight in the attic
  • Curling ridge caps or exposed underlayment
  • Flashing problems around chimneys, vents, and valleys
  • Ice-dam history or signs of moisture in the attic

According to roofing manufacturer GAF, these signs suggest replacement over mere repair. GAF

Roof Deck

The structural platform (often plywood or OSB) on which roofing materials are installed.

Measurement:

Accurate measurements are critical. For asphalt shingle roofs, you divide the total surface area by 100 to get “roofing squares” (one square = 100 sq ft) when calculating materials and labor. GAF Many roofing contractors now use tools such as satellite imagery and specialized apps to measure quickly. GAF

Pro Tip:

Ask your roofer if they provide a digital measurement report (e.g., via GAF QuickMeasure) so you know the size, waste factor, pitch, and materials needed – this reduces surprises on installation day.

Choosing Materials and Contractor

Question: Which shingles and which local roofing company should I pick?

Materials:

  • Asphalt shingles are the dominant choice for residential roofing across the U.S. and Michigan, because they cost less and are easier to install. GAF
  • Brand matters. For instance, GAF is North America’s largest roofing manufacturer and certifies certain contractors to give stronger warranties. GAF
  • If you’re selecting between brands like GAF or CertainTeed, check their warranty options and whether the contractor is “Factory-Certified”.

Contractor:

  • Choose a local roofing company experienced with Michigan weather (snow loads, ice dams, proper ventilation for cold climates).
  • Ensure they are licensed, insured, and can provide roofing system warranties, not just material warranties.
  • Ask for references, check local reviews, and verify they are comfortable working with permits in areas such as Saginaw, Midland, Bay City, Traverse City, and Harbor Springs.

Pro vs. Con: Hiring a Certified Contractor

Pros

  • Certified teams can offer stronger warranties
  • Better trained in proper roof system installation
  • More likely to understand local Michigan code & climate issues

Cons

  • Generally, a higher upfront cost
  • Might require more lead time (busy season)

 

Roofing System Warranty

Warranty that covers not just the shingles but the full installed system (underlayment, ventilation, flashing) AND workmanship when done by a certified contractor.

Budgeting & Financing

Question: How much will this cost, and how can I afford it?

As of 2023, the average cost of replacing an asphalt shingle roof in the U.S. is about $14,959. GAF Keep in mind this average includes many regions and sizes; your cost in Michigan may vary due to local labor, permit costs, disposal of old materials, snow-load requirements, etc.

Factors that influence cost:

  • Size and pitch of your roof
  • Complexity (dormers, hips, valleys)
  • Materials chosen (basic vs premium)
  • Local building codes and permit fees
  • Removal of old roof vs overlay
  • Ventilation improvements, attic insulation
  • Warranty type and contractor certification

Financing Options

Many local roofing companies (including Herbert Roofing) offer roof financing (monthly payments) or help you apply for home-improvement loans. Also, replacing your roof now may save on future repair costs (which would be more costly if damage occurs before replacement).

Pro Tip:

Ask your roofer for a written estimate that clearly separates the material cost, labor cost, disposal, and permit costs. Also, ask for warranty details and have them explain the financing options.

Scheduling and Pre-Installation Preparation

Question: What should I expect before installation day?

Once you’ve selected your contractor and signed a contract, the following steps are:

  • Schedule the replacement; peak roofing season in Michigan is often late spring through early fall (avoid deep winter if possible).
  • Permits & inspections: Your contractor should handle the local permit process for your city (Saginaw, Midland, etc.).
  • Material delivery: Shingles, underlayment, and flashing materials will arrive before installation.
  • Prepare your property:
    • Remove vehicles from the driveway if roofers need access.
    • Clear valuables (sensitive electronics) from the attic in case of vibrations.
    • Board up or protect landscaping near the house (shingle nails can scatter).
  • Old roof removal plan: If your roof has two or more layers of shingles, local Michigan codes may require a full tear-off.
  • Weather contingency plan: Since Michigan weather can change rapidly, agree with your roofer on a backup date or plan in case of rain or snow.
    Underlayment

    The layer (often felt or synthetic membrane) installed between the roof deck and the shingles. It acts as a secondary water barrier, especially important if shingles are damaged or during heavy snow melt.

    Installation Day

    Question: What happens on the actual replacement day?

    Here’s a typical flow:

    1. Tear Off: Removal of existing shingles (and possibly underlayment) down to the roof deck.
    2. Deck inspection/repairs: Any damaged decking will be replaced.
    3. Install underlayment & ice-dam barrier: Critical in Michigan’s climate, where snow/ice melt can freeze at eaves.
    4. Flashing & ventilation work: Install or upgrade flashing around chimneys, vents, and valleys. Proper attic ventilation is key to shingle longevity.
    5. Shingle installation: Lay the chosen asphalt shingles (GAF, CertainTeed) per manufacturer’s specifications.
    6. Cleanup & disposal: Contractor should haul off old materials and leave the site tidy; nail sweep or magnet to clear stray nails.
    7. Final inspection & homeowner walkthrough: You’ll have the chance to review the roof and ask questions.
    Pro Tip:

    On installation day, keep an eye (from a safe vantage) on how thorough the tear-off is, whether flashing and underlayment are being upgraded as promised, and ensure the job crew is from your selected contractor.

    Post-Installation Inspection & Warranty Registration

    Question: What should I do after the roof is installed?

    • Walk the roof perimeter with your contractor (from ground level) for final review.
    • Request all warranty documentation (manufacturer and workmanship).
    • Register your warranty with the manufacturer (often the contractor does this on your behalf). Manufacturers like GAF highlight this as part of a proper system installation. GAF
    • Take photos of the new roof for insurance records.
    • Review maintenance instructions: cleaning gutters, trimming overhanging branches, and checking attic ventilation.
    Manufacturer Warranty vs. Workmanship Warranty
    • Manufacturer Warranty covers roofing materials (shingles, underlayment), subject to the terms.
    • Workmanship Warranty covers how the roof was installed (flashing, deck prep, ventilation). Make sure you receive both.

    Maintenance Plan & Longevity

    Question: How do I ensure my new roof lasts as long as possible?

    In Michigan’s climate, longevity is enhanced by:

    • Scheduling annual roof inspections (especially after winter or major storms).
    • Cleaning debris (leaves, branches) off roofs and in gutters.
    • Maintaining attic ventilation and insulation (to prevent ice dams and excessive heat).
    • Watching for moss or algae and addressing quickly — they can shorten shingle life.
    • According to This Old House, climate and maintenance are significant factors in lifespan variation. This Old House
    • Respect the warranty conditions (for example, some warranties require certified installation, restrict walking on shingles, or limit colors).
    • Consider adding features such as ridge vents or ice-dam barriers if they are not already installed.

    How Roof Replacement Works in Michigan’s Climate

    When you live in Michigan (snow, freeze/thaw cycles, high winds by the lakeshore), these climate-specific considerations matter:

    • Ice dams: Without proper underlayment and ventilation, melting snow refreezes at eaves and forces water under shingles. Use an ice-dam barrier.
    • Snow load & steep pitch: Roof pitch affects snow shedding; steep roofs may cost more but shed snow more reliably.
    • Wind/snow exposure: Particularly in Bay City, Traverse City, or Harbor Springs near the Great Lakes. Choose shingles rated for higher wind resistance.
    • Temperature swings: These cause expansion/contraction, which can reduce shingle life.
    • Regional code/permit differences: Roofing requirements may differ by county or municipality; your local roofing company should know.

    Undertaking a roof replacement is one of the most significant investments you’ll make for your home, especially in Michigan’s climate. By working with a trusted local roofing company like Herbert Roofing, choosing the right materials (such as GAF or CertainTeed asphalt shingles), and following a transparent process from inspection through maintenance, you’ll protect your home, enhance curb appeal, and improve resale value.

    Frequently Asked Questions About Roof Replacement in Michigan

    1. How do I know if I need a full roof replacement or just repairs?

    If your roof only has a few missing or cracked shingles, a quick repair might do the trick. But when you see widespread curling shingles, granules collecting in your gutters, multiple leaks, sagging areas, or sunlight peeking through your attic, it’s usually time for a full roof replacement. In Michigan, where harsh winters and temperature swings take their toll, waiting too long can make the damage worse. According to GAF, these symptoms indicate that a new roof will better protect your home than ongoing patchwork repairs.

    2. How long does an asphalt shingle roof typically last in Michigan?

    Under normal conditions, asphalt shingle roofs last about 20–30 years. However, Michigan’s freeze-thaw cycles, heavy snow, and moisture can shorten that lifespan. If your roof is nearing 20 years old, it’s smart to schedule an inspection.

    3. What brands and warranties should I look for when replacing my roof?

    Two of the most trusted roofing brands in the U.S. are GAF and CertainTeed. Both offer multi-layer roofing systems designed for durability and backed by strong manufacturer warranties. The key is hiring a factory-certified contractor, like Herbert Roofing, because certification allows you to qualify for enhanced system warranties that cover not just the materials, but also the workmanship. GAF recommends registering your new roof to ensure the warranty remains active.

    4. Can I finance a roof replacement, and what should I budget for?

    Yes — most local roofing companies, including Herbert Roofing, offer roof financing options or can help you apply for a home-improvement loan. This makes it easier to spread out payments rather than paying the full amount up front. The average asphalt shingle roof replacement in the U.S. was around $14,959 in 2023 (according to GAF data), but your exact cost will depend on your roof size, materials, and design complexity. A certified contractor can help you customize a quote that fits both your budget and your long-term home goals.

    5. What should I expect on installation day, and how can I prepare?

    Roof replacement day can be busy, but it’s a smooth process when you plan. The crew will start by tearing off the old shingles and inspecting the deck for damage. Then they’ll install underlayment, flashing, and ice-dam barriers, followed by your new shingles. Before the team arrives, move vehicles out of the driveway, cover or move outdoor items, and protect landscaping from debris. A reputable roofer will handle cleanup, magnet sweep for nails, and a final inspection to ensure everything meets code.
