Commercial Roofing FAQs

How do I prevent ponding water on my commercial roof?

Ponding water, the accumulation of water on a flat roof, can lead to:

• Leaks
• Structural damage
• Premature roof deterioration

To prevent it:

• Proper Design and Installation: Ensure your roof has a sufficient slope for proper drainage during the design and construction phase.
• Regular Inspections and Maintenance: Inspect the roof regularly for clogged drains or debris buildup.
• Repair Sagging Areas: Address any sagging or low spots on the roof, as they can trap water.
• Tapered Insulation: Consider installing a tapered insulation system to create a gradual slope toward the drains.

What are the different types of roof warranties?

Two main types of warranties:

• Manufacturer's Warranty: Offered by the manufacturer of the roofing materials and typically covers defects in the materials themselves, such as premature failure, curling, or discoloration. The length of the warranty can vary depending on the material and manufacturer, ranging from a few years to a lifetime.
• Contractor's Warranty: Provided by the roofing contractor and covers the quality of the installation workmanship. This warranty typically covers leaks or other issues that arise due to improper installation and is usually for a shorter period, often 1 to 10 years.

Some manufacturers or contractors may offer additional warranties:

• Extended Warranties: Options to extend the standard warranty period for an additional cost.
• Specific Warranties: Covering specific aspects of the roofing system, such as ponding water resistance or wind uplift resistance.

What are the different types of commercial roofing systems?

There are several types of commercial roofing systems commonly used, each with its own advantages and disadvantages:

• Built-Up Roofing (BUR): A traditional, multi-layered system consisting of alternating layers of asphalt and reinforcing fabric. It's known for its durability, waterproofing capabilities, and affordability.
• Modified Bitumen Roofing: A single-ply system that uses asphalt-based sheets modified with polymers for enhanced flexibility, durability, and weather resistance. It's a versatile and cost-effective option for various commercial buildings.
• Single-Ply Membrane Roofing: A modern system using a single layer of waterproof membrane, typically made from EPDM (ethylene propylene diene monomer) rubber, TPO (thermoplastic polyolefin), or PVC (polyvinyl chloride). These membranes offer excellent waterproofing, energy efficiency, and ease of installation.
• Metal Roofing: Known for its longevity, durability, and fire resistance, metal roofing is a popular choice for commercial buildings. Available in various styles, including standing seam, corrugated, and metal shingles.
• Spray Polyurethane Foam (SPF) Roofing: A spray-applied roofing system that forms a seamless, monolithic membrane, providing exceptional insulation, waterproofing, and energy efficiency.
• Green Roofing: A system that involves covering the roof with vegetation, soil, and drainage layers. Offers environmental benefits, including reduced stormwater runoff, improved air quality, and energy efficiency.

Choosing the best roofing system depends on various factors, including your budget, building structure, climate, and specific needs. A qualified commercial roofing contractor can assess your roof and recommend the most suitable option.

What is a roof maintenance plan, and why is it important?

A roof maintenance plan is a schedule of regular inspections, preventative maintenance, and minor repairs designed to extend the lifespan of your commercial roof and prevent costly problems. Regular roof inspections are a key part of this plan. They help identify issues like:

• Minor Leaks
• Loose or Damaged Flashing
• Clogged Drains
• Debris Buildup
• Signs of Wear and Tear

Addressing these issues promptly can prevent them from escalating into major problems requiring extensive repairs or even a premature roof replacement.
