Best asphalt shingles?
Some choices are even tougher than Hillary Clinton v. Donald Trump…
We’re using a conventional wood-frame house as a combination of office and home. It was built in the late 1960s with perhaps 10 inches of fiberglass between the rafters. There are cathedral ceilings everywhere, hence no possibility of insulating an attic (no attic! Also no basement; architects back then were smart enough to foresee that America would become less cluttered and there would be no need to store anything). The basic shape of the house is the same as a double-wide trailer home. (But of course Zillow estimates the value at about $1 million due to the proximity to Boston and the general impracticality of building anything new in Massachusetts.)
A local architect suggested putting nail-base foam panels on top of the existing roof deck. This gives 3.5 inches of foam and and then another 0.5″ of OSB to which shingles can be nailed. Apparently this is a fairly common retrofit insulation technique for old-yet-modern-style houses like this one. There would be some foam injected into any gaps between the panels.
We then have a choice of whether to do ice-and-water shield over the entire roof or just the lower 6′. The advantage of not doing the whole thing is that maybe water vapor would have a better chance to escape?
On top of the ice-and-water shield we then have to pick shingles. This is where I am hoping to get answers from readers! Consumer Reports tested shingles in 2009 and found that high-end Owens Corning Berkshire Collection and CertainTeed Grand Manor were the best (strongest). Owens Corning Oakridge and CertainTeed Landmark were pretty good at about one third the price. The roof is only about 3750 square feet including budgeted waste, so I don’t think that the shingle price difference will be that large in the overall context of the project.
What do folks who’ve been through this recently have to say? How did you choose a shingle and what did you choose?
One more idea: Should we try to hold out for another year and get the Tesla solar energy tiles? It looks like a good product, but I wonder if it will be shipped within my lifetime. Also you probably wouldn’t want to do the north side of your house with these, right? So then you are supposed to find matching non-solar shingles for the north side?
[Note that this continues the theme of why you want to rent rather than buy; the brain of the homeowner is entirely filled up with boring stuff.]
