Hi folks,
Our place has a cathedral ceiling with a tin roof - guessing it's around 100 years old.
The last owners converted the roof to an office space/spare room with a low roof in order to make the most of the space.
The attic space at the end of the sealed room gets incredibly hot in summer mainly due to radiant heat of the tin which does not have sarking.
The ventilation of the roof is ok. The temps in the morning are fine and they drop off after the sun goes down. There are pictured ridge vents that move air through from the eaves.
It gets so hot that the attic door swings open and pushes hot air into the office space. While we have a split system and I accept that we are literally in the hottest part of the house; anything to bring temps down a bit would be great.
Looking for any advice on reducing the extreme temps in the roof so we can continue to use it for storage.
Thanks to everyone in advance. First time poster, long time viewer!
Cheers,
Welcome to the Bunnings Workshop community @LHScrewdriver. It's terrific to have you join us, and many thanks for your question about reducing heat in an attic.
The most effective solution would be to insulate the roof to help prevent heat transfer. I would suggest the easiest option would be to use Foilboard. It will be easy to cut and fit in between the ceiling rafters. You simply need to install the spacers by adhering them to the roof sheets with gutter silicone. Once the spacers are secured, you can cut your sheets to size and glue them to the spacers.
A note to our New Zealand members: the use of foil insulation products is prohibited.
Please let me know if you have any questions.

Another thought @LHScrewdriver. Although you are getting plenty of airflow with the eave vents, it would be worth considering a roof vent to help that air transfer through the roof and be sucked out at the top. We have a wide range of roof vents to choose from but these Bradford CSR SolarXVENT 150mm Solar Powered Vent - Night Sky would be a great option.
