I thought I had posted in this thread, but I guess not.....My house here in Florida had a light gray cheep assed shingle roof on it when I bought it 22 years ago, wish I had known what would happen....
one time up there at 1130 am, house facing directly west, and on east side of house, northern Florida, the shingles about took my skin off...got my IR probe from the car hobby, and measured 165f in the MORNING before the 3 pm heat of the day even.....the underlayment was 145f.....attic down at ceiling height for sheetrock/rooms was 105f........I started painting the roof white, and dropped the attic underlayment temps by FORTY degrees, same time of day a week or so later....house is one story, slab, garage on right side of house, uphill and it's south side of course, the HVAC unit is behind/side of the garage, wedged loosely between a fence/gate and a storage shed built on side of the house....
close to 18 years ago, I replaced all the single pane aluminum windoze in the house with windoze that were in stock at Home Despot next door, started with the 5' tall and ~7' wide pix window....white vinyl double glass, gas filled, lo E, with a ~18" casement window on each side, fixed center glass, no grids.....dropped my LR temps by a noticeable amount in the afternoon sun...redid all the rest of the windoze too....total cost ONE thousand bux....did the installs myself of course....
latest project is that the shitty shingles on front of the house, facing the PM sun of course insisted on failing, in spite of the white coatings on them, so I have been putting white metal over top of them, 16 feet long strips 6 of them at 3' wide, and roof peal caps of course....400 bux for the material of course.....plus a roll of tar like tuff paper between it and the shingles.....I feel the temp drop already and it's only been 3 daze.....
when it's bright sun in the afternoon on that metal, I plan on getting a temp reading of the metal, on the ground it was about 90f something, but up there it may hit 120f I suspect.....I will see soon enough.....more interesting would be the temp of the underlayment......
watt pisses me off, is me not having the knowledge/thought to do this 20 years ago, and cut my HVAC bill by some 40%......
