What makes a mid century modern flat roof unusual
Eichler homes, built across the Peninsula and South Bay from the late 1940s into the 1970s, were designed as post-and-beam houses with low-slope or gently pitched roofs. Their construction leaves no margin for a sloppy roof job:
- No attic: exposed plank decking forms the finished ceiling, so a leak shows up as a stain on wood you look at every day.
- Beams through the wall: glulam or solid beams extend past the glass to the eaves, and their ends sit right at the roof edge.
- Slim fascia: the roof edge is a few inches thick by design; extra layers change how the house reads from the street.
- Little original insulation: many still have the thin roof assembly they were built with, so rooms bake in summer and chill in winter.
- Atriums and courtyards: center atriums in many models collect water and leaves from the surrounding roof planes.

An Eichler roof job with us can cover any of these:
- Repairs at seams, drains, skylight curbs and beam-end edges.
- Foam recoating, or full removal down to the planks.
- Tear-off and replacement in foam, single-ply or modified bitumen.
- Top-side insulation with a matched fascia extension.
- Skylight reflashing and atrium drain resets.
Eichler roof repair: the problems we see most
Original tar-and-gravel roofs on these homes are long gone or failing. Most Eichlers we visit now carry spray foam, single-ply or modified bitumen from a reroof decades ago, and each ages in its own way.
Foam roofs whose coating has worn through start to pit and absorb water. Single-ply seams open near skylights and plumbing vents. Patches pile up around the low-profile drains and scuppers until water backs up. The most expensive problem is hidden: water that tracks along the top of the decking to a beam end, then rots the beam where it meets the eave. We probe beam ends and edge boards on every Eichler inspection and photograph anything soft.

Which systems suit an Eichler roof replacement?
| System | Why owners choose it | What it needs |
|---|---|---|
| Eichler foam roof (spray polyurethane plus coating) | Insulation and waterproofing in one seamless layer; can be shaped to improve drainage | Coating renewals on schedule; protection from foot traffic |
| Rigid insulation under single-ply (TPO or PVC) | Defined insulation value, white reflective surface, welded seams | Careful edge design so the added thickness stays discreet |
| Modified bitumen cap sheet | Durable and easily repaired; works where little thickness can be added | A cool-rated cap where energy rules call for reflectivity |
There is no single correct choice. The deciding factors are how much insulation you want, how much edge thickness you will accept, and how you feel about recoating a foam roof over the years.
Can Eichler roof insulation be added without changing the profile?
Mostly, with planning. Because there is no attic, insulation has to go on top of the deck, which raises the roof surface. We keep the street view slim by tapering the insulation down toward the edges, using a fascia extension sized to match the original proportions, or stepping the insulation back from the perimeter. Interior options exist too, but they cover the wood ceiling most owners want to keep visible.

Protecting exposed beams, roof edges and atriums
- We inspect from the roof and from inside, probing beam ends and noting each ceiling stain, then draw the proposed edge profile on the estimate.
- We check beam ends for softness and replace or cap decayed sections before the new roof covers them.
- Edge metal is fabricated to the house's proportions, and the membrane laps over it so water drips clear of the beam ends.
- Drains and scuppers are reset at the new roof height and strainers added where oaks or street trees shed into them.
- Atrium edges get extra attention, because water and leaves from several roof planes converge there.
- After the final inspection, we haul away old roofing, clean the atrium and walk the new edge with you.
Where a leak is isolated, a targeted flat roof repair at an edge or drain may be all an Eichler needs.
What shapes the cost of an Eichler reroof?
We quote Eichler work after measuring and probing the roof. The number moves with variables these houses have and most others do not:
- Insulation goal: going from a bare plank deck to inches of foam or rigid board changes both material and edge work.
- Beam ends and edge boards: decayed wood is replaced before roofing, and the extent shows only once probed.
- Existing layers: old foam, gravel or a prior recover to strip.
- Edge metal: fascia extensions fabricated to the house rather than bought off the shelf.
- Skylights and atrium drains: the number of curbs and low points to flash and reset.
- Design review: extra planning time where a city applies Eichler guidelines.

Eichler roofing in Cupertino, Sunnyvale, Palo Alto and beyond
We work in Eichler tracts throughout Santa Clara County, including neighborhoods in Sunnyvale, Cupertino, Palo Alto, Mountain View and San Jose. Each city runs its own permit process, and some have adopted design guidance for their Eichler neighborhoods. Palo Alto and Sunnyvale have both published Eichler design guidelines, so check with the city planning department before changing roof edges, profiles or skylight layouts. Palo Alto alone has roughly 2,700 Eichlers, more than any other city. Every reroof needs a permit, so confirm the C-39 license of whoever bids yours with the CSLB.
California's Title 24, Part 6 cool-roof rules can also apply to low-slope reroofs, depending on the city's climate zone and the scope of work. We confirm both the energy and the design requirements with the jurisdiction before ordering materials. Owners adding a rooftop deck or a balcony over living space should also see our roof deck waterproofing page.

Stains on your Eichler ceiling boards? Call (725) 745-8803 and we'll inspect the roof above them.
Call (725) 745-8803Why Eichler owners call a family-run roofer
We are a family-run team, and an Eichler gets the same free, written and itemized estimate as any job, with photos of beam ends, drains and edges taken from the roof. If a targeted repair or a recoat will carry the roof a few more years, we say so. During the work we tarp the atrium and garden, clean up every day and haul away old foam and gravel. Small jobs, like one leaking skylight curb, are welcome.
