Roofing in Moon Valley, Phoenix, AZ
Moon Valley's custom homes from the 1960s were built low and wide, with shallow pitches, flat sections and big overhangs. Those designs look great and leak in predictable places. We repair, recoat and re-roof them without losing the mid-century lines owners love.
Short answer
Moon Valley homes most often need repairs on low-slope and flat sections, foam or membrane replacement where old built-up roofs have failed, and re-roofs on pitched sections that still carry aging shingles or tile. We look closely at drainage, fascia and the joints between roof types, then recommend materials that suit each slope rather than forcing one product across the whole house.
Moon Valley grew up around its golf course in the 1960s, and builders favored long, low homes with shallow roof pitches, flat sections over living areas and deep overhangs that shade the windows. Those lines are part of what draws buyers to the neighborhood. They also mean many roofs here sit at slopes too shallow for tile or standard shingles to shed water reliably, especially when a monsoon storm drops a lot of rain at once.
Over the decades, owners have covered these sections with built-up roofing, rolled roofing, foam or whatever the roofer of the day preferred. When we inspect a Moon Valley home, it is common to find two or three systems on one house, plus remodels that changed the original drainage. Our first job is to understand where water is supposed to go and where it actually goes, and to check for low-slope repairs that were done without fixing the drainage behind the leak.

For many homes here, yes. Spray foam can be built up thicker where water ponds to create slope where there was none, it weighs little, and it adds insulation to rooms that bake under a flat roof all summer. It also ties cleanly into the edges and penetrations that tend to leak on older built-up roofs. The coating is the part that wears, and it needs renewing every 5 to 10 years depending on the product.
Not every section suits foam. On pitched portions we usually recommend tile, shingles or stone-coated steel, and on homes where owners want a crisp modern edge, a membrane may suit the design better. Where an old built-up roof has blistered and split, we tear it off to the deck, repair any soft sheathing and then install a new foam roof. Where the existing roof is sound, a recoat or targeted repair may be all that is needed for now.
Those deep overhangs are wood, and their fascia boards and rafter tails take water every time a low-slope roof overflows at the edge. Add sprinklers on big lawns and decades of sun breaking down the paint, and the ends of the boards soften. Rot often stays hidden until a gutter pulls loose or a section of soffit sags. Birds and bees then move into the gaps, which makes the damage worse.
We replace damaged fascia and soffit, fix the edge detail so water leaves the roof cleanly, and add gutters sized for the overhang where water spills onto walkways or patios. Moon Valley is a short drive up I-17 or Seventh Street from our Phoenix office. A pre-monsoon visit in spring is the ideal time to catch soft fascia and ponding spots before the summer storms test them, while the repairs are still small ones.

Learn moreTile needs a minimum slope to shed water, and many Moon Valley sections fall below it. On those areas we recommend foam, a membrane or a low-slope system instead. Where the pitch allows tile, we can install it and tie it carefully into the low-slope sections next to it.
Ponding usually comes from sagging deck, built-up layers that have settled, or drains and scuppers that sit too high. On Moon Valley homes it often comes from remodels that changed how the roof drains. We find the cause and correct it with foam slope, tapered build-up or drain changes.
If the existing roof is wet, has more than one old layer, or sits on soft decking, a tear-off is the right call. If it is dry and sound, some systems can be recovered with foam. We take core samples and check the deck from below to tell you which applies.
