When it comes to protecting your commercial property, your roof is one of the most critical investments you’ll make. The right roof system not only safeguards your building from Michigan’s harsh winters and summer heat but also contributes to energy efficiency, structural integrity, and long-term operational costs. Choosing the correct roof for your facility requires a careful assessment of your building’s needs, budget, and long-term goals.

At Motor City Roofers, we guide Detroit-area business owners through the process, ensuring they select a roofing solution that delivers maximum value, performance, and protection.

1. Understand Your Facility’s Needs
Before looking at specific roofing systems, you must evaluate your building’s unique requirements:

• Roof Shape and Pitch – Low-slope and flat roofs require different systems than steep-slope designs.
• Building Use – Warehouses, manufacturing plants, retail centers, and office buildings have different internal climate and operational demands.
• Foot Traffic – Some roofs need walkways for HVAC maintenance or other rooftop activity.
• Weather Exposure – Detroit experiences snow, ice, high winds, and intense summer sun—your roof must withstand extreme seasonal changes.

2. Know the Main Types of Commercial Roof SystemsEach roof type has advantages and drawbacks. Your choice will depend on your building’s structure, budget, and performance expectations.

A. Built-Up Roofing (BUR)

• Description: Layers of bitumen alternated with reinforcing fabrics and finished with a top layer of gravel or mineral cap sheet.
• Pros: Excellent waterproofing, durability, and UV protection.
• Cons: Heavier than other systems, longer installation time.

B. Modified Bitumen

• Description: Asphalt-based sheets reinforced with fiberglass or polyester, applied in multiple plies.
• Pros: Flexible, easy to maintain, great for extreme temperatures.
• Cons: Requires skilled installation to prevent seam issues.

C. Single-Ply Membrane (EPDM, TPO, PVC)

• EPDM: Rubber membrane with excellent weather resistance and flexibility.
• TPO: Energy-efficient white reflective surface, strong seam integrity.
• PVC: Resistant to chemicals, grease, and punctures—great for restaurants or industrial facilities.
• Pros: Lightweight, quick installation, minimal maintenance.
• Cons: Vulnerable to punctures if not protected.

D. Metal Roofing

• Description: Panels made from steel, aluminum, or copper.
• Pros: Exceptional longevity (40+ years), low maintenance, great for sloped commercial roofs.
• Cons: Higher upfront cost, noise during rain without proper insulation.

E. Green Roofing

• Description: Roof system covered in vegetation over a waterproofing membrane.
• Pros: Outstanding insulation, stormwater management, environmental benefits.
• Cons: Higher installation and maintenance requirements.

3. Consider Lifespan and Maintenance Needs
While cost is important, focusing only on the lowest bid can lead to higher long-term expenses. Instead, consider:

• Expected Lifespan:
  • EPDM: 20–30 years
  • TPO/PVC: 20–25 years
  • Metal: 40–50 years
  • BUR/Modified Bitumen: 20–30 years
• Maintenance Requirements: Some systems need annual inspections and minor repairs to maintain warranties.

4. Evaluate Energy Efficiency
Detroit’s climate demands a roof system that performs well in both hot and cold weather:

• Reflective Roofs (TPO, PVC, White-Coated BUR) help reduce summer cooling costs.
• Insulation Levels impact winter heating expenses.
• Cool Roof Technology can lower energy use and extend roof life by reducing heat absorption.

5. Factor in Resistance to Local Hazards
Michigan weather challenges roofs with:

• Snow and Ice Loads: Choose a roof with strong structural support.
• Freeze-Thaw Cycles: Select materials that won’t crack or delaminate.
• Wind Resistance: Ensure your system meets or exceeds Detroit building codes for high-wind events.
• Ponding Water Resistance: Especially for flat roofs, proper drainage is essential.

6. Budget for the Long-Term
Instead of thinking only about initial cost, calculate the life-cycle cost:

• Installation Cost – What you’ll pay upfront.
• Maintenance Costs – Regular inspections, cleaning, minor repairs.
• Energy Savings – How much your roof will lower utility bills.
• Replacement Cost – When it will need to be replaced.

A slightly more expensive roof system that lasts longer and reduces energy bills often ends up costing less over time.

7. Choose the Right Contractor
Even the best roofing material will fail prematurely if installed incorrectly. Partner with a trusted local expert like Motor City Roofers who:

• Has extensive experience with Detroit’s commercial roofing needs.
• Is licensed, insured, and manufacturer-certified.
• Provides detailed written estimates and warranties.
• Has a proven track record of satisfied clients.

8. Don’t Forget About Warranties
Roof warranties vary widely and can cover:

• Materials Only – Protects against manufacturing defects.
• Workmanship – Covers installation quality issues.
• Full System – Offers the most comprehensive protection.

Review warranty terms carefully and understand your maintenance obligations to keep them valid.

9. Plan for Proper Drainage and Accessories
A well-chosen roof system also needs:

• Adequate Drainage – Scuppers, gutters, and downspouts sized correctly for your roof area.
• Walk Pads – To protect membranes from maintenance foot traffic.
• Snow Guards (for Sloped Roofs) – Prevent dangerous snow slides.

10. Consult the Experts Before Deciding
Every commercial property is unique, and what works for one may not suit another. That’s why Motor City Roofers provides free consultations to evaluate:

• Your building’s structure and use.
• Energy efficiency goals.
• Budget constraints.
• Longevity expectations.

We then recommend the optimal roofing system tailored to your needs—whether that’s a high‑performance TPO, a durable EPDM, a classic BUR, or a long‑lasting metal roof.
