How do you install a TPO roofing membrane
Membrane. It's time to install the membrane. It is positioned over the installation. Board with chalk lines to ensure proper alignment.
How is TPO roofing applied
Installation. The TPO membrane can be applied in 3 ways: fully adhered with bonding adhesive; mechanically attached; or mechanically attached just at the seams. TPO is always heat-welded at the seams and at accessories. Heat welding creates a monolithic bond between sheets or from sheet to accessory.

Can TPO roofing be installed over plywood
TPO roofing is a single-ply membrane that can be installed over plywood. Although there are different types of roofing materials available, TPO is preferred as it is cost-effective. TPO roofing is also preferred as it is long-lasting and can protect the roof for a few years to come.
Which side of the roofing membrane do you put
printed side facing
Breathable membrane should be installed with the printed side facing upwards. This is clear on our WRAPTOR products, making this stage very simple. Always ensure that the membrane overlaps the UV resistant layer ending at the guttering.
Which way does roofing membrane go
facing outwards
Unroll the breathable membrane and lay it out parallel with the roof eaves. With most brands of membrane, the printed side will be facing outwards. However, always ensure to double check any installation instructions provided by the manufacturer.
Does TPO require underlayment
Underlayment
Like the cover board, an underlayment is usually made out of gypsum and acts as an extra layer under the insulation. This can improve the fire rating for buildings that require it, but isn't necessarily essential to the TPO roofing system.
Do you coat a TPO roof
Coatings like asphalt emulsion and acrylic are effective solutions that will extend the life of TPO roof systems. They're cost-effective and easy to install, which is particularly advantageous when a new roof is an unexpected expense.

Does TPO require a cover board
TPO can be applied directly to polyiso insulation without the use of a cover board. With EPS and XPS insulation, a cover board is typically specified by the manufacturer.
What goes between plywood and metal roofing
roofing felt layer
The longer answer is that when metal roofing is installed, it is always best to use a roofing felt layer between the metal roofing and the bare plywood. This should always be used as a bare minimum, but some people also choose to add an extra layer with a slip sheet that can also help safeguard the felt sheet.
How thick does plywood need to be for a roof
Recommended Roof Sheathing Thickness
The thickness of conventional roof sheathing ranges from 5/8″ to ½” thick. If you're installing OSB for your rooftop, a thickness of 5/8″ is advised. While plywood should be ½” thick. The recommended roof sheathing thickness is ⅝” thick.
Can you put a membrane on a wet roof
If the surface is damp or wet, the EPDM products and membrane won't successfully adhere to the surface.
Should roof membranes be tight
Never pull your roof membrane under tiles too tight
The ideal measurement of this will sit between a minimum of 10mm and a maximum 15mm. If the membrane is taught, there is risk of tearing and the water could become trapped behind the tiling batten.
Do you put membrane before or after insulation
After the insulation is fitted, an airtight membrane/ vapour control layer must be applied to the warm side of the insulation, otherwise all the hard work you put into insulating and protecting your home will literally leak at the seams!
Where do you place a breather membrane
'Breather membranes' are installed to the outer side of the insulation – for example, either over or under the counter-battens on a pitched roof – and allow water vapour to escape from inside a building without the need for ventilation. They also repel any water, most commonly rain, that tries to enter the building.
Should you coat a TPO roof
Installing Roof Coatings Over TPO
Coatings like asphalt emulsion and acrylic are effective solutions that will extend the life of TPO roof systems. They're cost-effective and easy to install, which is particularly advantageous when a new roof is an unexpected expense.
How thick should a TPO roof be
No matter which option is chosen below the membrane, this is how all TPO roofs are sealed at the seams. TPO is typically sold in thicknesses of 45 mil, 60 mil and 90 mil. In Indiana, we typically see 45 mil and 60 mil specified. The thicker the membrane, the better the long term durability.
What is the best sealer for a TPO roof
Silicone and acrylic coating systems are both great choices for restoring and extending the life of a TPO roofing system.
What kind of paint do you use for TPO
Then, based on recommendations from a national coating and paint company in Canada, the best paint to use to paint a TPO roof is elastomeric paint. If you use a good quality elastomeric paint, then that will eliminate the need to use a surface primer first.
How many layers of roof underlayment do I need
Overlapping 19 inches will ensure that the underlayment is at least two layers thick all over the roof. So, underlayment on low-slope roofs should overlap 19 inches. Remember that underlayment on steep-slope roofs should overlap 2 inches.
Do you seal a TPO roof
If your TPO has a fleece backing then Lap Sealant will probably be the right choice. But if your TPO does not have a fleece backing then Dicor Ultra Sealant System should be used.
Do you need an air gap under a metal roof
Research has confirmed that creating an air space under a metal roofing system will increase energy savings during both summer and winter months. A study was funded by the U.S. Department of Energy and conducted by the Oak Ridge National Laboratory to document energy savings of metal versus asphalt roofs.
Do you need a vapor barrier under a metal roof
Without one, water can get trapped in the wall, which will produce moisture and ultimately other issues like rot, mold, and trouble with thermal performance. Vapor barriers are recommended for under metal roofs.
Should I use 1 2 or 3 4 plywood for roofing
Half- or three-fourths-inch Plywood for Roof Sheathing: Traditionally, half-inch CDX plywood was the common choice with 24-inch rafter spacing. However, heavier roof loads may require the use of three-fourths-inch CDX plywood for roof sheathing.
