At MJY Construction, we hear many of the top commercial roofing questions from Brockton business owners who want to make informed decisions. In this guide, we’ll answer the most common commercial roofing FAQs to help you understand everything from materials to warranties and inspections.
Common Commercial Roofing FAQs in Brockton
1. What Are the Best Commercial Roofing Materials?
Choosing the right material for your commercial roof affects its durability, maintenance needs, and long-term cost. The best options include:
- TPO (Thermoplastic Olefin): Popular due to its energy efficiency, affordability, and reflective properties that reduce cooling costs.
- EPDM (Ethylene Propylene Diene Monomer): A rubber roofing material known for its durability and ability to withstand extreme weather.
- PVC (Polyvinyl Chloride): Excellent for waterproofing and chemical resistance, making it ideal for restaurants and industrial facilities.
- Modified Bitumen: A flexible, multi-layer asphalt-based system that provides excellent durability.
- Metal Roofing: Extremely long-lasting, fire-resistant, and ideal for reducing heat absorption.
Each material has benefits depending on your climate, budget, and building type.
2. How Long Do Commercial Roofs Last?
Lifespan depends on the material and maintenance:
- TPO & PVC: 20-30 years
- EPDM: 25-30 years
- Modified Bitumen: 15-25 years
- Metal Roofing: 40+ years
Regular maintenance extends a roof’s lifespan by preventing minor issues from becoming major repairs.
3. How Much Does a Commercial Roof Replacement Cost?
The cost of replacing a commercial roof varies based on:
- Roof size and complexity
- Choice of materials
- Labor costs
- Insulation and underlayment needs
On average, commercial roof replacement costs between $4 and $12 per square foot. However, getting an expert assessment is the best way to determine an accurate estimate.
4. How Often Should a Commercial Roof Be Inspected?
Roofing professionals recommend inspections twice a year—once in the spring and once in the fall. Additional inspections should be conducted after severe weather events, such as storms or heavy snowfall.
The National Roofing Contractors Association (NRCA) (nrca.net) states that regular inspections help identify minor problems early, preventing costly repairs later.
5. What Are the Signs That a Commercial Roof Needs Repairs?
If you notice any of the following signs, call a professional roofer immediately:
- Water stains on ceilings or walls
- Ponding water on the roof
- Cracks, blisters, or bubbles in roofing material
- Loose or missing flashing
- Unexplained spikes in energy bills
Addressing small issues early prevents them from becoming expensive repairs.
Important Questions About Commercial Roof Maintenance
6. Why Is Regular Roof Maintenance Important?
Maintenance helps prevent leaks, extends the lifespan of your roof, and improves energy efficiency. The U.S. Department of Energy (energy.gov) highlights that regular maintenance can lower energy costs by ensuring a building remains properly insulated.
7. Can Small Leaks Be Ignored?
No! Even a small leak can lead to major structural damage over time. Water infiltration weakens the roof deck, causes mold growth, and damages interior walls and ceilings.
8. What’s Included in a Commercial Roof Maintenance Plan?
A proper maintenance plan typically includes:
- Routine inspections
- Small repairs (sealing minor leaks, replacing flashing)
- Gutter and drain cleaning
- Checking insulation and ventilation
A proactive approach can save thousands of dollars in long-term repairs.
9. How Can I Prevent Ponding Water on My Roof?
Flat commercial roofs are prone to ponding water, which can lead to leaks and structural damage. To prevent this:
- Ensure proper drainage system installation
- Keep gutters and downspouts clear
- Install tapered insulation to improve water flow
FAQs About Weather and Environmental Impact
10. How Do Harsh Weather Conditions Affect Commercial Roofs?
Brockton experiences a wide range of weather conditions that can impact commercial roofs:
- Snow & Ice: Heavy snowfall can put excess weight on a roof, leading to structural stress. Ice dams can also form, causing water damage.
- High Winds: Winds can loosen roofing materials and cause leaks.
- Rain & Moisture: If drainage systems are clogged, standing water can weaken the roof.
- Heat Exposure: Temperature fluctuations can cause roofing materials to expand and contract, leading to cracks over time.
11. How Can I Make My Commercial Roof More Energy Efficient?
To improve energy efficiency:
- Install reflective roofing materials to reduce heat absorption
- Add insulation to improve temperature regulation
- Ensure proper ventilation to prevent heat buildup
These measures can significantly reduce heating and cooling costs.
