new project that is way overdo ( painting the barn roof )

hi folks,, back into the painting gear again,, last year it was my home, this year its the barn roof,,  it will take a few days,, but can take a few weeks, cause i need it to be nice sunny not to hot for me to work up there,,  one days work,, i figure it will take me 4-5 more days to complete,,  its really not that bad,, its getting up there and handling the heat,,  so hopefully tomorrow i will be at it again,,  i will get it done,, i have around 12000 sf of roofing all together,, but only doing about half of that,,  the black roof will be done next year just some patch work this year after the painting of the aluminum painting is done,,  a little at a time
