Commercial rooftops are increasingly busy places. HVAC equipment, solar panels, exhaust systems, satellite equipment, signage, and other additions may all be necessary for building operations – but installing them isn’t as simple as placing equipment on the roof.
Any new rooftop equipment has the potential to affect waterproofing, drainage, warranties, and the long-term performance of your roofing system. Before installation begins, here are a few things property managers should consider:
Roof Penetrations Create Vulnerable Areas
Many rooftop installations require new penetrations for pipes, electrical lines, ductwork, or equipment supports. Every penetration creates another area that must remain watertight.
Improper flashing or sealing can create an entry point for moisture and eventually lead to leaks beneath the roof membrane.
Coordinating with your roofing contractor ensures these areas are properly integrated into the existing roofing system.
Consider the Weight and Placement
Where equipment is installed matters.New equipment may add significant weight to the roof or require supports that weren’t part of the original system. Placement can also interfere with drainage patterns or create areas where water and debris collect.
Before installation, the appropriate professionals should evaluate whether the proposed location is suitable for the equipment and existing building conditions.
Don’t Forget About Foot Traffic
Installation is only the beginning. HVAC technicians and other service professionals may need regular access to rooftop equipment throughout its lifespan. Increased foot traffic can damage membranes, particularly when tools or heavy components are being moved across the roof.
Designated walk pads and planned access routes can help protect high-traffic areas.
Know Your Warranty Requirements
Modifying a warrantied roof without following the appropriate procedures can potentially complicate future warranty claims.
Before work begins, review your roof warranty and determine whether the manufacturer or roofing contractor needs to approve or document the modifications. A quick conversation beforehand can prevent a much larger issue later.
Bring Your Roofing Partner in Early
One of the easiest ways to protect your roof is to involve your roofing contractor before – not after – new equipment is installed. Your roofer can review the proposed location, identify potential concerns, coordinate flashing and waterproofing details, and document the work appropriately.
That collaboration helps everyone do their job while protecting the integrity of the existing roof.
Protect the Roof You Already Have
Rooftop upgrades are sometimes unavoidable. Damage to the roof underneath them doesn’t have to be. A little coordination before installation can help prevent leaks, preserve warranty coverage, and protect the long-term performance of your roofing system.
At TALTEK, we work with property managers and other trades to make sure changes on the roof don’t compromise the investment underneath them. Before your next rooftop project begins, bring your roofing partner into the conversation.
