Commercial Roofing FAQs

How do I choose the right roofing material for my commercial building?

Choosing the right roofing material for your commercial building requires careful consideration of various factors:

• Building Type: The type of building, its size, and its intended use will influence the most suitable roofing material.
• Roof Slope: The roof's slope or pitch will determine the type of roofing system that can be installed and the drainage considerations.
• Budget: Different roofing materials have varying costs. Establish a clear budget for your project and consider the cost of materials, installation, and long-term maintenance.
• Durability and Lifespan: Assess the durability and expected lifespan of different roofing materials, considering factors like weather resistance, UV resistance, and foot traffic.
• Energy Efficiency: Choose materials with good insulation and reflectivity properties to reduce energy consumption and lower heating and cooling costs.
• Aesthetics: Consider the appearance of the roofing material and how it complements the building's design and surroundings.
• Fire Resistance: Prioritize fire-resistant materials, especially for buildings with specific fire safety requirements.
• Maintenance Requirements: Consider the ongoing maintenance needs of different materials. Some materials require more frequent cleaning or repairs than others.

Consult with a qualified commercial roofing contractor for expert guidance on suitable roofing materials for your specific building and needs.

What is a roof drain, and how does it work?

A roof drain is a plumbing fixture designed to collect water from the roof surface and direct it into the building's drainage system. It's a critical part of a flat roof's drainage system, preventing ponding water and ensuring proper water runoff. Roof drains typically consist of:

• Drain Strainer: A grate or screen that prevents debris from clogging the drainpipe.
• Drain Body: Collects the water from the roof.
• Drainpipe: Connects to the building's drainage system, directing the water away.

How do I choose the right type of roof access hatch?

Consider these factors when selecting a roof access hatch:

• Roof Type: The type of roof (flat, sloped, metal, etc.) will determine the appropriate hatch style and material.
• Size and Accessibility: Choose a hatch size that provides enough space for easy access and consider the location and surrounding obstructions for ease of use.
• Usage: Determine how frequently the hatch will be used and for what purposes. This will help you select a hatch with the appropriate durability and features.
• Safety Features: Prioritize hatches with safety features like handrails, non-slip surfaces, and locking mechanisms.
• Energy Efficiency: If energy efficiency is a concern, choose a hatch with good insulation and a tight seal.

Consult with a qualified roofing contractor or a roof access hatch supplier to find the best option for your needs.

Why do I need a roof curb for my HVAC unit?

Installing an HVAC unit on a roof curb is essential for:

• Proper Drainage: The curb elevates the unit above the roof surface, allowing water to drain away from the unit, preventing corrosion and potential damage.
• Waterproofing: The curb provides a solid base for flashing, ensuring a watertight seal around the unit's penetration point.
• Airflow: A properly designed curb allows for adequate airflow around the HVAC unit, improving its efficiency and preventing overheating.
• Maintenance Access: The curb provides a stable and accessible platform for maintenance personnel to service the HVAC unit.
