I have a 20' x20' (400 sq. ft.) sunroom that had a black shingle roof.
It became hotter in the summer than the outside temperature.
With the pitch of the roof, the actual roof area might have been 450 sq.
ft.
I painted it with Henry Solarflex 287 SF Brilliant White Elastomeric
Roof Coating.
It is not advertised as a coating for asphalt shingled roofs, but I just
tried it before spending big $$$ for switching to a light colored shingle.
It's been 4 years and it is still white. Also, the coating has greatly
reduced the shedding of the granular surface of the shingles.
Bought it Home Depot. It came in a 5 gallon plastic can, and I have
about 1/4 of it left.
YMMV

Hi,
Black shingle for sun room? it makes sense, LOL! My two sun rooms have
laminated Al. panels. With R value of 20 foam core. 17 year old, still
looks as new.
