Commercial Roofing FAQs

What is the process for a commercial roof installation?

The commercial roof installation process generally involves the following steps:

1. Assessment and Planning: The roofing contractor will assess your roof's condition, take measurements, discuss your needs and budget, and recommend a suitable roofing system.
2. Permitting: The contractor will obtain the necessary permits from your local building department, ensuring compliance with building codes.
3. Material Delivery: The roofing materials will be delivered to your site.
4. Site Preparation: The contractor will prepare the work area, including setting up safety barriers, protecting surrounding property, and ensuring access for equipment.
5. Removal of Existing Roof (if applicable): If replacing an existing roof, the old roofing materials will be carefully removed and disposed of properly.
6. Roof Deck Preparation: The contractor will inspect and prepare the roof deck, making any necessary repairs or reinforcements to ensure a solid foundation for the new roof.
7. Installation of Underlayment: A waterproof underlayment will be installed on the roof deck to provide an additional layer of protection against leaks.
8. Installation of Roofing System: The new roofing system will be installed, following the manufacturer's specifications and local building codes.
9. Flashing and Edging: Flashing will be installed around chimneys, vents, skylights, and other penetrations to prevent leaks. Edge metal will be installed along the roof's perimeter for a finished look and proper water drainage.
10. Inspection and Cleanup: The contractor will conduct a thorough inspection of the completed roof to ensure proper installation and address any potential issues. They will then clean up the work area and remove any debris.

What is a roof access hatch?

A roof access hatch, also known as a roof hatch or access door, is an opening in the roof that provides safe and convenient access to the roof surface. They are essential for:

• Maintenance and repairs
• Equipment installation and servicing
• Inspections
• Emergency egress

Roof access hatches come in various sizes and styles, designed for different types of roofs and applications. They can be made from materials like metal, fiberglass, or wood and are typically equipped with safety features like handrails and locking mechanisms.

What are the signs that my commercial roof needs to be replaced?

Consider replacement if you see:

• Persistent Leaks: Multiple or recurring leaks despite repairs.
• Extensive Damage: Large areas of damaged or deteriorated roofing, beyond cost-effective repair.
• Ponding Water: Persistent standing water after rainfall.
• Sagging or Structural Issues: Sagging, deflection, or signs of structural damage.
• Age and Deterioration: If your roof is nearing the end of its lifespan and showing signs of widespread wear and tear.

A professional roof inspection can definitively tell you if you need a replacement.

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.
