Maintaining a commercial roof in Boston comes with unique challenges due to the region’s harsh winters, heavy rainfall, and fluctuating temperatures. Without proper maintenance, these environmental factors can lead to costly repairs and structural damage. This guide explores common commercial roofing problems in Boston and provides preventative measures to extend the lifespan of your roof.

1. Roof Leaks

Causes:

• Aging roofing materials

• Poor installation or repairs

• Damaged or deteriorated flashing

• Ponding water causing membrane degradation

Prevention:

• Schedule regular commercial roofing maintenance in Boston

• Inspect flashings and seams for damage

• Repair minor leaks promptly before they worsen

• Ensure proper drainage to prevent water accumulation

2. Ponding Water

Causes:

• Inadequate drainage system

• Structural sagging in flat roofs

• Clogged or blocked gutters and scuppers

Prevention:

• Install additional drains if necessary

• Keep gutters and downspouts clear of debris

• Conduct roof inspections after heavy rainfall or snowmelt

• Use tapered insulation to create proper slope and drainage

3. Flashing Failures

Causes:

• Expansion and contraction due to temperature fluctuations

• Poorly installed or aging flashings

• Improper sealing around vents, chimneys, and HVAC units

Prevention:

• Inspect flashing during seasonal maintenance checks

• Ensure proper installation by a qualified Boston commercial roofing contractor

• Replace or repair flashing as needed before major issues arise

4. Punctures and Membrane Damage

Causes:

• Debris from storms or nearby construction

• Animal activity (birds, rodents)

Prevention:

• Install walkway pads for safe access

• Conduct routine inspections to check for damage

• Remove debris immediately after storms

5. Snow and Ice Damage

Causes:

• Ice dams preventing proper drainage

• Excessive snow load leading to structural stress

Prevention:

• Ensure insulation and ventilation are adequate to reduce freeze-thaw damage

6. Blow-Offs and Wind Damage

Causes:
