Two paths
| Option | Best when |
|---|---|
| New foam over the existing roof | The roof is mostly dry but worn, eroded or badly sloped |
| Tear-off and TPO | Insulation or deck is wet, or there are too many layers |
New foam
A fresh layer of sprayed foam adds insulation, restores thickness and lets us build slope toward the canales. It's then coated. See spray foam roofing.
TPO
TPO is a white single-ply membrane over new insulation, with hot-air-welded seams. It's flashed up parapets and around canales and openings. Tapered insulation can fix long-standing ponding.
Old tar and gravel roofs
Many older Albuquerque homes still have built-up roofs under later layers. Whether foam can go over them depends on moisture and condition — an inspection tells you.

Common questions
Is new foam cheaper than TPO?
Often, when the existing roof can stay. Tear-offs add cost.
Which lasts longer?
Both can last many years. Foam needs periodic recoats; TPO needs inspections and occasional seam repairs.
