Do I need a radiant barrier with a metal roof?

If you are installing any type of roof that has an air space (either built in by the shape of the tiles or because of a batten system), then you should most definitely install a radiant barrier! These types of roofs are usually clay tile or slate roofs, metal shingle roofs & some standing seam metal roofs.

What is the best thing to put under a metal roof?

Felt Underlayment (Asphalt Felt/Tar Paper Underlayment) Known by many different names (including felt paper, roofing tar paper, and asphalt-soaked felt), felt underlayment is the most commonly used type of underlayment material on steep-slope metal roofs.

Are radiant roof barriers worth it?

Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.

Is Sarking required under metal roof?

When it comes to metal roofs, sarking is considered to be important as it prevents condensation that can cause rusting. In bushfire prone areas, metal roof sarking is mandatory as it can protect your home against airborne embers entering your ceiling space during a bushfire.

Should you insulate under a metal roof?

Yes, providing a layer of insulation under a metal roof is imperative because metal is naturally a better heat conductor than wood. Quality insulation helps a home retain heat in the winter and keep cool when the temperature dips.

How do you insulate under a metal roof?

Thankfully, there is a better insulation option for metal roofs than conventional fibre batts and insulation boards. Spray foam forms a continuous, air-tight seal under the metal roof in question. Spray foam fills all the holes, gaps, and cracks. The result is a superior insulation solution.
