Frequently Asked Questions About Roofing and Roof Replacement in Southeast Michigan
When it comes to protecting your home, few things are more important than your roof. In Southeast Michigan, our weather can be unpredictable — heavy snow in the winter, rain in the spring, hot summers, and plenty of wind in between. Because of that, many homeowners eventually ask the same questions about roofing and roof replacement.
If you are a homeowner in Metro Detroit or surrounding areas, this guide will help you understand everything you need to know about your roof, from the basics of maintenance to what to expect during a full roof replacement.
We’ve put together the most frequently asked roofing questions and answered them in simple, clear language. Let’s dive in.
Why is my roof so important?
Your roof does more than just cover your house. It’s your home’s first line of defense against rain, snow, wind, and extreme temperatures. A good roof:
-
Keeps your home dry and free of leaks.
-
Helps with energy efficiency by keeping heating and cooling costs lower.
-
Protects your attic, insulation, and walls from moisture damage.
-
Adds curb appeal and resale value to your home.
In Michigan, where winters can bring heavy snow and ice, a properly installed and well-ventilated roof is critical.
How long does a roof last in Michigan?
The lifespan of your roof depends on the type of materials used and the weather conditions. On average:
-
Asphalt shingles (the most common in Michigan): 20–30 years.
-
Architectural shingles (a higher grade of asphalt): 30–50 years.
-
Metal roofing: 40–70 years.
-
Cedar shakes: 25–35 years or much longer with maintenance (but less common here due to moisture).
Because of Michigan’s freeze-thaw cycles and harsh winters, roofs here may not last as long as in milder climates. Regular maintenance and proper ventilation can extend their life.
How do I know if my roof needs to be replaced?
Here are some clear warning signs:
-
Shingles are curling, cracking, or missing.
-
You see water stains on your ceilings or walls.
-
Your roof looks uneven or sagging.
-
Granules from shingles are collecting in your gutters.
-
The roof is more than 20 years old.
-
Ice dams form frequently in winter.
If you notice any of these, it may be time to call a roofing company in Southeast Michigan to inspect your roof.
Can I repair my roof instead of replacing it?
Sometimes, yes. If the problem is small — like a few missing shingles, a small flashing issue, or minor leaks — a repair might be enough.
But if your roof has widespread damage, is nearing the end of its lifespan, or has ventilation issues, a full replacement is usually the smarter investment. In Michigan, patching an old roof can sometimes waste money if the underlying problems aren’t solved.
How much does a new roof cost in Southeast Michigan?
The cost of a roof replacement depends on:
-
The size of your roof.
-
The slope or pitch of your roof.
-
The type of shingles or roofing material.
-
Whether decking or wood underlayment needs replacement.
-
Ventilation and insulation needs.
On average in Michigan, most asphalt shingle roof replacements range between $8,000 and $20,000. Architectural shingles and upgraded ventilation systems will be on the higher end, while metal roofing will cost even more but last much longer with less maintenance.
How long does a roof replacement take?
For most Michigan homes, a professional roofing crew can replace a roof in one to three days, depending on the size and complexity of the project. Larger homes, steep roofs, or roofs needing structural repairs may take longer.
Do I need to leave my home during a roof replacement?
No, you don’t have to leave, but be prepared for some noise. Crews will be tearing off shingles, hammering, and moving materials around. If you work from home or have small children or pets, you might want to plan around the noise for a couple of days.
What kind of shingles are best for Michigan weather?
Because Michigan deals with heavy snow, ice, and strong winds, architectural asphalt shingles are usually the best choice. They are thicker and more durable than traditional 3-tab shingles, and they hold up better to wind and ice.
Some top shingle brands used in Southeast Michigan include:
-
CertainTeed Landmark Pro
-
Malarkey Vista (SBS Modified)
-
Owens Corning Duration
These shingles are designed for long life and high performance in cold-weather states.
What is ventilation and why does it matter?
Roof ventilation allows air to flow through your attic space, keeping it cooler in summer and drier in winter. Proper ventilation is crucial in Michigan for two reasons:
-
It helps prevent ice dams, which form when warm air escapes into the attic, melts snow on the roof, and causes water to refreeze at the edges.
-
It extends the life of your shingles and roof decking by preventing moisture buildup.
Without good intake and exhaust ventilation, even a new roof can fail early.
What is an ice dam and how can I prevent it?
An ice dam happens when snow melts on the warm part of your roof and refreezes at the colder edges, creating a “dam” of ice. This blocks water from draining properly, and the backed-up water can leak into your home.
To prevent ice dams in Southeast Michigan:
-
Make sure your attic is insulated and ventilated correctly.
-
Use ice and water shield underlayment during roof installation.
-
Keep your gutters clear.
-
In heavy snow, use a roof rake to safely remove snow from your roof edges.
Do roofing companies work year-round in Michigan?
Yes — roofing companies in Southeast Michigan often work from spring through late fall. Winter installations can be done if needed, but cold weather can make shingles more brittle and harder to seal properly. The best time to replace your roof is usually spring, summer, or early fall.
Can I put a new roof over my old roof?
Michigan building code allows one additional roof layer in many cases. However, most reputable roofing contractors recommend a full tear-off instead of layering over old shingles.
Why? Because tearing off the old roof:
-
Exposes any hidden wood damage.
-
Allows proper installation of underlayment and ice/water shield.
-
Reduces extra weight on your home.
-
Ensures the new shingles last as long as they should.
How do I choose the best roofing company in Southeast Michigan?
Look for these qualities:
-
Local experience — A company that understands Michigan weather and building codes.
-
Good reviews — Check Google, Facebook, or the BBB.
-
Certifications — Such as CertainTeed ShingleMaster or Owens Corning Preferred Contractor.
-
Written warranties — Both from the manufacturer and the installer.
-
Clear communication — They should explain the process, pricing, and materials.
What warranties should I expect on a new roof?
Most premium shingles come with a limited lifetime warranty from the manufacturer, often 30–50 years. In addition, a roofing company should provide a workmanship warranty (often 5–15 years) to cover installation issues.
Always ask what is covered and make sure you get it in writing.
How do I maintain my roof in Michigan?
A roof is not “set it and forget it.” Regular maintenance can add years to its life. Simple steps include:
-
Cleaning gutters in spring and fall.
-
Trimming overhanging branches.
-
Checking for missing or damaged shingles after storms.
-
Having a professional roofing inspection every few years.
-
Raking heavy snow from the edges in winter to prevent ice dams.
