1970s built-up roofs and the Territorial homes after them

Carefree's early custom homes include 1970s mid-century designs with built-up flat roofs. Territorial and Santa Fe homes from the 1980s can list built-up and foam roofs, some with two HVAC units on top. Built-up roofing is layers of felt and asphalt, and after enough desert summers it blisters and opens at the laps, usually first around curbs and along the parapet.

When the old roof is dry and sound, we foam over it instead of tearing it off. The foam bonds to the existing surface and climbs the parapets and every curb, so there are no seams to fail. That matters on a roof crowded with equipment, where every penetration is a chance for a leak. It also insulates, which helps rooms that sit right under a flat deck.

Coating color and the town's standards

Bare foam needs a UV coating, and here the color takes some thought. The town's standard for homes keeps exterior colors at or below 40 percent light reflective value, and solar panels on a flat roof have to sit behind the parapet. A bright white coating keeps a roof cool, but where the roof shows from the road or from a hillside lot above, check with the town before you pick it. Elastomeric coatings come in other colors, and we'll walk through the options with you. A gravel finish is another way to protect the foam.

Repair, recoat or replace

A tired foam roof often needs a recoat, not a new roof. A blistered built-up roof may only need foam over the top. And on a home with both tile slopes and flat sections, you might not need to redo everything at once. Our post on partial versus full replacement talks through when a smaller job makes sense. Coatings do wear and need periodic recoating, and we'd rather show you that wear during an inspection than guess at a date. Hail and foot traffic leave small punctures in a coating. Caught early, they're a quick patch; left alone, water reaches the foam and the repair grows.
