Introduction: Reroofing With Corrugated Metallike and Radiant Barrier Over Asphalt Herpes zoster in 3 Steps!

Reroofing with a new roof over an older roof is comely more of a common practice, especially if you have an asphalt shingle roof and you're adding a different type of roof (like metal or roofing tile) over IT. This is as wel the time to make sure your new roof is going to do at its optimum electrical capacity and you'll likely only get one chance to get information technology moral. That's why using azygous-sided RoofingFoil™ during this process is useable, it will give every last the benefits of a time-honored carpet pad, merely it has an additional welfare of being a radiant barrier excessively.

If you give an existing shingle roof and you're provision along adding a metal roof on top of the shingles without doing a tear away of the old roof, then this is how you should do IT.

Materials needed:

  • Perforated, single-sided RoofingFoil™ refulgent roadblock
  • Woody battens/furring strips (1x's OR 2x's) - not pressure burnt
  • Roofing cap nails (nails with a elastic automatic washer attached)
  • Corrugated metal roofing panels
  • Bimetal fasteners for metal roofing

Footfall 1: Step 1: Apply Radiant Barrier Over the Old Shingles

Considering the cost alone of a new roof, the beaming barrier is a no-brainer add-on. When you are adding radiant roadblock bilk over an present roof, you need to use the perforated foil. The perforations allow the foil to respire and they preclude wet from getting trapped between the old roof and the transparency layer. The perforations are tiny bittie holes that will allow the moisture to pass through, yet they are quieten small adequate to provide a secondary waterproof layer against liquid water.

The foil slope e'er has to face an air space in monastic order to work; if the new roof will get on a batten system of rules, the battens will create the necessary air space (we recommend no to a lesser degree a 1/2" air gap).

Wind off the single-sided RoofingFoil™ with the bilk side facing up, toward the sun. Purpose roofing cap nails to secure the foil edges to the old roof. Since the battens will croak on incoming, you don't have to worry about securing the foil too much, the battens will really hold it in situ. Take off at the bottommost of the roof and work your way up to the peak with the hydrofoil, overlapping seams a few inches on the way (no need to tape the seams).

If the roof will non use battens, then you will want to guarantee the foil a littler better than if it were using them.

Once every last the foil is in position, you're ready for the next step.

Footmark 2: Step 2: Instal the Battens/Furring strip Strips (if Using) Over the Foil

After the roof is covered with the RoofingFoil™, information technology's prison term to put in the spacers (furring strips/battens) to the roof. How you establis battens can affect the how well the roof drains and cools, so make sure you consider that when you'Re adding them. Additionally, the battens will create the air space that is required for the foil to work to reverberate radiant heat back. A shield-shaped batten system where the strips are staggered horizontally or spaced separated will work too. The main theme is that you want a system where air can easily flow and irrigate seat easily run out.

The RoofingFoil™ is irregular and will not rip or tear. So you force out walk connected it as you're installation the battens without worrying about destroying the product. Get the battens in place so you're ready for the last step!

Step 3: Step 3: Add Metal Roofing Panels

Now that you suffer covered the experient shingles with the RoofingFoil™ and secured the battens connected top, you're ready to add the roof happening!

Secure the metallic element panels using the fasteners and finish the roof instalmen.

With the addition of a radiant barrier ABOVE the roof bedight, the bottom of the roof deck should be close to ambient temperature (this assumes you own decent attic ventilation). This means you will eliminate just about Completely the radiant heat that would come away the deck with traditional black felt underlayments.

Watch the 1 Min video below to see how RoofingFoil™ works to block the radiant heat from getting in to your territory and, ultimately, your home:

The result is a spiky-performance roofing system that reduces beamy passion gain by 97%! That means disregardless what type of metal Oregon tile you choose (including color) the beamy barrier will block 97% of the radiant heat from the sun from getting through the roof and into your plate. Your home will rich person contiguous energy nest egg, and be many comfortable class goblet-shaped.
