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.

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.

How do I choose a commercial roofing contractor?

Choosing the right commercial roofing contractor is crucial. Look for the following qualities:

• Experience: Seek a contractor with proven experience in commercial roofing, especially with the type of system you need (flat, metal, etc.).
• Licensing and Insurance: Verify their licensing and insurance (liability and workers' compensation).
• Reputation: Check online reviews, ratings, and testimonials from previous clients.
• Professionalism: Choose a contractor who is responsive, communicates clearly, provides detailed written estimates, and stands behind their work with warranties.
