The summer sun beats down mercilessly on your roof.
You can
see the heat waves rising off its surface, and you
wonder if
those shingles, while adequate for keeping out rain and
snow,
are really any good at keeping out the heat.
Time to put up the roof tent.
Depending on the application,
the roof tent may be
tethered
along the perimeter of the roof or secured to poles on
ground.
The tent's material withstands storms and gusts of wind
as its
white (or otherwise reflective) surface casts a shadow on
the
home and bounces that nasty sunlight away.
How about a more solid colored roof?

I've always wondered why our rooves are so

Largely because of conservative building regulations
and planning laws. |

[V] actually, knowledge gleaned from from those "can you get hotter than the sun" posts, in the winter you'd want to put the foil on at night to bounce heat back into the house, in the summer during the day to keep it out. |

Best is to get solar. That's what I used to tell. |

Some people plant deciduous trees on the south side
their hour for this purpose. In the summer the
leaves block the sun. In the winter the leaves are
gone, allowing sun to enter the house. |

People with holes in their roofs pull those blue plastic tarps over them. A fine experiment would be attic temperatures with or without the tarp. |
