Whether you’re facing an urgent leak or planning a future roof replacement, chances are you’ve got questions—lots of them. Roofing can be confusing, especially when you’re not sure which materials to choose, how long your roof should last, or who to trust with the job. In Troy, MI, where weather plays a big role in roof performance, knowing the right answers is critical.


At 180 Contractors Roofing & Siding, we’ve heard every roofing question in the book. That’s why we’ve compiled this go-to list of frequently asked roofing questions to help homeowners make smarter, more confident decisions about their homes.


How Long Should a Roof Last?

This is probably the most common question—and the answer depends on the materials used and how well the roof is maintained. In Michigan’s climate, traditional asphalt shingles typically last 15–25 years. However, premium materials like metal or architectural shingles can last 30–50 years with proper care.


Weather, ventilation, and maintenance also play a role. Even the best roofing materials can fail prematurely if exposed to excessive moisture or poor installation.


What Are the Signs My Roof Needs to Be Replaced?

Watch for these warning signs:

  • Missing or curled shingles
  • Frequent leaks or water stains on your ceiling
  • Moss or mold growth
  • Sagging roofline
  • Granules collecting in gutters


If your roof is more than 20 years old and showing multiple signs of wear, it’s likely time for a replacement.


Do I Need a Full Replacement, or Just Repairs?

This depends on the extent and location of the damage. Minor issues—like a few missing shingles or isolated flashing problems—can typically be repaired. However, widespread damage, water infiltration, or old age may require full replacement to ensure long-term protection.


A professional inspection will help determine which solution makes the most sense and whether your home is eligible for insurance coverage.


How Much Does a New Roof Cost?

Roofing costs vary widely based on materials, roof size, complexity, and labor rates. On average, homeowners in Troy can expect to pay between $8,000 and $18,000 for a full roof replacement. Higher-end options or large roofs may cost more.


Although price is important, quality and warranty should weigh just as heavily in your decision. You want a roof that performs well—and lasts.


How Long Does Roof Installation Take?

A standard asphalt shingle roof on an average-sized home typically takes 1–3 days to complete, depending on weather and complexity. Larger or more intricate roofs, or those with multiple layers that need to be removed, may take longer.


At 180 Contractors Roofing & Siding, we provide a detailed timeline and keep you informed throughout every phase of your project.


What Roofing Material Is Best for Michigan Homes?

Because of Michigan’s varied climate, homeowners need materials that stand up to wind, snow, ice, and sun. That’s why we often recommend Owens Corning roofing systems, which offer impact resistance, energy efficiency, and enhanced protection against the elements.


They also come in a wide range of styles and colors, so you don’t have to sacrifice curb appeal for performance.


Can I Install a New Roof Over the Old One?

While it’s sometimes possible to install new shingles over old ones, we rarely recommend it. Doing so can trap heat and moisture, reduce lifespan, and may void manufacturer warranties. A tear-off allows for full inspection of the decking and ensures a longer-lasting result.


Will My Homeowners Insurance Cover Roof Damage?

Yes—if the damage is caused by a covered peril like hail, wind, or falling debris. Normal wear and tear or neglect, however, usually aren’t covered. That’s why documenting your roof’s condition with annual inspections is crucial.


We work with homeowners and insurance adjusters to streamline the claims process and ensure fair coverage when applicable.


Do I Need to Be Home During the Roofing Project?

It’s not required, but it can be helpful, especially for larger projects or when final decisions are needed. We take extra care to protect landscaping, minimize debris, and maintain communication even if you’re away during installation.


How Do I Choose the Right Roofing Contractor?

Look for a licensed, insured contractor with a proven track record, strong references, and clear communication. Local experience is especially important in Michigan, where weather and building codes vary from season to season.


180 Contractors Roofing & Siding brings years of local expertise, certified crews, and a commitment to transparency from start to finish.


Final Thoughts: Knowledge Is Your Best Tool

Understanding the basics of roofing empowers you to ask the right questions, spot problems early, and hire the right team. Whether you’re preparing for a new installation or evaluating roof damage after a storm, knowing what to expect can make the entire process smoother and less stressful.
