Key Roofing Considerations During New Commercial Construction Projects

Every successful commercial building begins with a solid foundation, and the roof is an essential component. A building needs to be watertight before the interior buildout can begin. Commercial roof installation decisions made during the planning stage have a lasting impact on the facility’s overall performance.

• - Coordinate timelines with other trades
• - Assist with penetration locations
• - Ensure proper flashing details
• - Protect completed roof sections during construction
• - Help with leak prevention

Early collaboration leads to a smoother installation process and fewer issues after tenant occupancy.

Plan for Rooftop Equipment Before Installation

Modern commercial roofing systems often include:

• - HVAC units
• - Exhaust fans
• - Gas and ammonia lines
• - Safety walkpads and accessories

Planning these elements before roof installation allows contractors to properly account for rooftop equipment while helping ensure the building remains watertight.

This proactive approach helps prevent premature roof failure and simplifies future maintenance needs.

Understanding Warranty Coverage Requirements

CentiMark’s Single Source Warranty:

Our comprehensive Single Source Warranty covers all aspects of your commercial roof, including:

• - Workmanship and labor
• - Materials
• - Drains and scuppers
• - And more!

If a warranty issue arises, we handle all the repairs, labor, materials and more at no additional cost.

Warranty Provision:

Based on decades of historical data, such as the number of roofs under warranty, the warranty durations, roof types and actual costs in prior years, we know that warranty expenses average about 0.75% of a project’s value. For every job we complete, we add that amount to our Warranty Provision, a dedicated liability on our balance sheet for future warranty work.

Manufacturer warranties often require proper installation, documented maintenance and approved repairs to remain valid.

Before construction, verify:

• - Manufacturer warranty coverage
• - Contractor workmanship coverage
• - Maintenance requirements
• - Inspection schedules
• - Approved repair procedures

Your Options for Maximum Protection

Instead of juggling multiple warranty providers or separating contractor and manufacturer coverage, building owners can choose a streamlined approach that aligns under one coordinated system.

Our Single Source Warranty can be bundled with or used alongside a manufacturer warranty, depending on the project needs and overall facility goals. This flexibility allows owners, general contractors and facility managers to select the level of protection for their asset. This flexibility is especially valuable for large commercial portfolios where consistency, documentation and scalability are key priorities.

By addressing warranty strategy during the construction phase, owners can ensure their roof investment is fully protected from day one. 

Plan for Future Commercial Roof Maintenance Needs

Every commercial roof will require inspections and maintenance throughout its service life. Including maintenance considerations during construction makes future service safer and more efficient.

Features to consider:

• - Roof access points
• - Walk pads and designated walkways
• - Drainage systems

Buildings designed with maintenance in mind typically experience fewer emergency repairs and a longer roof service life.

Proper Drainage is Essential

Standing water is one of the leading causes of premature roof deterioration.

During construction, verify that the roof design includes:

• - Properly sized drains
• - Overflow systems
• - Crickets where necessary
• - Tapered insulation where needed

Effective drainage solutions protect your roof system while reducing the risk of leaks and structural damage.

Why Early Planning Matters

Commercial roofing is more than just the top layer of a building. It is a critical component that protects operations, equipment and employees.

Involving a commercial roofing contractor early in the construction process allows project teams to:

• - Build proper solutions for your project
• - Coordinate with other trades
• - Protect roof warranties
• - Properly plan for the life of the warranty
• - Plan for long-term roof maintenance and service

The result is a roof system designed to perform reliably for decades to come.
