I don't know what it was about the 1950's that predisposed houses and hairstyles to be flat, but I did make an awesome discovery regarding our roof!
I revisited the plans left behind by the former owners. According to the plans drawn by Caywood and Associates back in 1979, extraordinary measures were taken to improve the roof, including a layer of foam insulation.
As most Eichler owners are aware, the roof can be a real challenge to maintain. At least two different installation companies in the Bay Area specialize in foam roofing for flat top and low slope roofs.
We are currently in the process of getting a two year certification for our roof and I will be sharing these extensive roof remodel plans from 1979 with our roofer.
