In all due respect to John Hammerschmidt he should check with someone that has done the actual heating load calculations for Eichlers such as myself. In both Eichlers I have done this for most of the heat loss is through the windows - not the roof. This is true even for R4 roofs. The roof is usually the second most important. But since the roof is much more affordable to insulate it does make sense to put it first on the list of energy efficiency improvements. Even a modest amount of roof insulation (R10) will reduce this loss to a comparatively minor one. Its worth a little extra to do more but the returns diminish rapidly past R19 or so. Note that summer time heat gain through the roof should also be considered. Heat reflective surfaces help a great deal but if you don't have that a higher R-value can help too.
With those roofs, a green roof possibiity becomes interesting.
Eichler houses are, by definition, exclusive and elite. Yet, due to their unusual structure they require special attention in the windows and doors area. Since usual Eichler has more window surfaces than any other house of the same size, such problems as temperature loss, noise, condensation and security become acute and require immediate solution.
We, at Aurora Windows & Doors, are proud to offer this solution to the Eichler homeowners - our premium windows will make your house more beautiful than ever and solve these issues.
My neighborhood in San Jose is not listed- apparently it is not exclusive enough. Our Eichlers were pre-atrium and built in 1953-54 just east of San Jose City College. Originally, Eichler homes were attactive to a lot of "people of color" because they were one of the few if not the first to be INCLUSIVE, to NOT have restrictive rules about who they would sell to. Unlike other builders, Eichler sold to Jews, to African-Americans, to Asians, and to anyone who had the money to buy a home. My neighborhood once housed non-white faculty at San Jose City College and at San Jose State College (now University). There were some pretty amazing people who lived here including a princess from Indonesia. Progressive, forward thinking, highly educated people bought in this neighborhood.
