Quick answer: When a swamp cooler comes off an Albuquerque roof, it leaves a curb or platform, a duct opening and often a patch of water-damaged deck. Closing it properly means removing the curb, repairing the deck, framing the opening and tying new roofing into the existing roof. A sheet-metal cap over an abandoned curb is the shortcut that tends to leak later.

Why so many coolers are coming off
Albuquerque is one of the last large metro areas where swamp cooling is still widespread, and more homeowners convert to refrigerated air every season. Coolers struggle during monsoon humidity, and many owners decide the unit on the roof is no longer worth keeping.
Some keep the cooler for dry months after adding refrigerated air. If yours is staying, the curb flashing deserves a check instead of removal.

What the cooler leaves behind
A cooler sits on a curb or platform, drops air through a duct cut into the roof, and carries water for months. The city's hard water scales up pads and lines, lines leak or overflow, and the water ends up on the roof around the curb.
By the time the cooler comes off, the curb is often soft and the deck around it stained or rotted. That is the part that needs real repair, not just the hole where the duct went.

How the opening should be closed
The curb and roof jack come out down to the deck. Soft decking around the opening is replaced, the opening is framed and decked to match the roof, and the roof system is rebuilt over it: welded membrane on TPO, matching plies on mod-bit, filled and recoated foam, or rewoven shingles. Our cooler removal and roof patch page covers the details.

Shortcuts to avoid
An empty curb with a loose lid collects water and rots the deck under it. A sheet-metal cap screwed over the opening relies on sealant that dries out in a few summers. Both look finished on the day and become leaks later, often right over a ceiling.
If the roof around the cooler is old and patched, removing the cooler can be a sensible moment to look at the whole roof instead of one more patch.

Who does what
Your HVAC contractor disconnects the water and power, installs the new system and deals with the duct inside the house. The roofer removes the cooler and curb from the roof and closes the opening. Coordinating the two avoids a gap of days with an open hole in the roof, which matters in monsoon season.
FAQ
Common questions on this topic
It is better removed. Empty curbs collect water and are a common leak point.
It can work briefly, but it depends on sealant that dries out. A proper patch lasts as long as the roof.
It is built from the same system, though older roofs may show a color difference.
We lift it off the roof once your HVAC contractor has disconnected it.
Your HVAC contractor seals or removes it; we close the roof side.
If the roof is near the end of its life, yes.
Many owners do. If so, check the curb flashing instead.
