Yes, ice and water shield can be used under metal roofing. It is important to use underlayment in any roofing application to protect the roof deck from moisture, and ice and water shield is an ideal material for this purpose.
Ice and water shield is a bituminous roofing material with a rubberized adhesive on one side and a mineral surface on the other. The rubberized adhesive provides a strong bond to the roof deck, helping to keep moisture out and reducing the risk of water damage.
The mineral surface is designed to allow the roofing material to adhere to it. It is important to install ice and water shield according to manufacturer’s instructions, but most applications require that it be applied 6” up the roof deck and 6” onto the sides.
The ice and water shield should be installed before any metal roofing is applied to ensure proper performance.
What underlayment should be used under metal roofing?
Underlayment is the material that goes between the metal roofing and the roof deck. It provides additional weather protection and acts as a secondary water barrier in the event that any water gets through the metal roofing.
The underlayment needed will depend on the type of roofing material, the climate and the local building code requirements. In general, the best underlayment to use under metal roofing is a synthetic roof underlayment, such as ProArmor from GAF or Tiger Paw from Owens Corning.
Synthetic roof underlayment is designed to resist the water and can provide additional insulation and protection for the roofing underneath.
It is important that the underlayment be installed properly, as any gaps or overlaps in the material can lead to water leakage and other issues. Properly installed synthetic roof underlayment is water and wind resistant, and can provide additional protection against harsh climates.
It is also more durable than traditional felt paper, which is the most commonly used type of underlayment for metal roofing.
Overall, synthetic roof underlayment is the best option for underlayment under metal roofing. It provides additional water and wind protection, as well as durability and insulation. It is important to remember to properly install the underlayment, as any errors can lead to leaks and other damage.
Do you need ice guard on metal roof?
Yes, it is recommended to use ice guard on metal roofing systems. Ice guard helps protect the roofing system from the buildup of ice dams and snow, which can cause significant damage, including leaking and structural integrity issues.
Ice guard is a waterproof membrane, made of rubber-like materials, that is installed along the eaves of a roof, helping to prevent water from entering and backing up under the roof. Ice guard also helps reduce the amount of snow and ice that can accumulate on a metal roof.
In areas where heavy snow and ice are frequent, it is especially important to have an ice guard installed on the metal roof.
Can I use felt paper under metal roof?
Yes, you can use felt paper under a metal roof. Felt paper, which is also known as asphalt-saturated felt or sometimes just “tar paper”, provides an extra layer of protection to your roof and works especially well with metal roofs.
It helps keep out moisture, prevents rusting, reduces noise, and makes the roof more energy-efficient. It also helps fasten nails better, which is necessary because metal roofs are usually installed using staples or nails.
Felt paper can be applied with either hot-tar or cold-tar roofing adhesives or it can be stapled or nailed down. If you choose to nail it down, be sure to use roofing nails that are long enough to penetrate through all layers of the roof, including the felt paper.
To ensure proper protection, felt paper should have at least one foot of overlap when overlapping pieces and the entire roof, including felt paper, should be properly sealed along the edges.
How do you keep a metal roof from Condensating?
Keeping a metal roof from condensating requires proper insulation, ventilation, and drainage. In order for a metal roof to be effective, it needs to be properly insulated. An appropriate type of insulation should be installed between the underside of the roof and the attic, or in the roof structure itself, to prevent any external air from entering the space.
Additionally, the insulation should be designed specifically to the climate of the building’s location.
A good ventilation system should also be incorporated into a metal roof in order to reduce the buildup of condensation. This can be done by incorporating natural ventilation techniques such as ridge and soffit vents, or using a powered attic fan.
The addition of these ventilation techniques help to keep temperatures and humidity levels balanced within the building and prevent condensation.
Finally, proper drainage should also be incorporated into the metal roof design. If the roof collects a large volume of condensation, it needs to be able to allow this moisture to escape from the building.
Proper drainage should be included in the design of the roof to prevent any potential leaks. By incorporating the proper insulation, ventilation, and drainage systems into the design of the metal roof, you can keep condensation from forming and reduce the risk of damage.
How do you insulate a metal roof?
To insulate a metal roof, the most common approach is to use a metal roof insulation system. This type of system typically consists of a metal roof deck, metal roof battens, and rigid roof insulation boards.
This metal roof insulation system can be covered with a variety of different roofing materials, such as metal roofing, shingles, tile, or landscaping membranes. Before applying the insulation system, a moisture barrier is often installed over the metal roof deck to prevent moisture from entering the building.
Once the moisture barrier is in place, the metal roof battens and rigid roof insulation boards can be installed. The battens help to increase the stability of the roof and secure the insulation boards in place.
The insulation boards typically come in pre-cut pieces that are placed between the metal roof battens. The roofing material is then installed over the insulation boards before the roof flashing is applied around the perimeter of the roof and any openings are caulked to further prevent moisture from entering the building.
Do I need underlayment for metal roof over shingles?
Yes, you do need an underlayment for a metal roof over shingles. This underlayment provides a protective layer between the existing shingles and your new metal roofing. It also helps protect against water, air and vapor that can damage your roof.
The underlayment keeps water from getting into the roof sheathing, preventing potential damage from rot and mold. It also helps increase the overall life and stability of your new roof. Depending on the type of metal roofing you choose, you will likely need a particular type of moisture barrier.
Most underlayment is made out of either asphalt-saturated felt or rubberized asphalt membrane. Asphalt-saturated felt is usually 4-6 mil thick and provides good protection against water, air and vapor.
However, it doesn’t offer as strong of protection as rubberized asphalt membrane.
Rubberized asphalt membrane is thicker and more durable than asphalt-saturated felt and is best used in places that are susceptible to extreme temperatures and high winds. Additionally, some metal roofs require the use of an approved underlayment product, so be sure to consult with a roofing professional to determine what type of product is best for your new roof.

Can I use ice and water shield instead of shingles?
No, you cannot use ice and water shield in place of shingles. Ice and water shield is a specialized membrane used as an additional waterproofing layer over a roof before the shingles are installed. It is almost always installed along the eaves, around chimneys, and in any other areas where extra protection against water damage is needed.
The membrane is normally applied over the roof plywood and lays beneath the shingles and should not be used in place of the shingles. It is meant to add an extra layer of waterproofing and should not be used in place of the shingles.
Should I use ice and water shield on my whole roof?
When it comes to using ice and water shield on your roof, the decision really depends on your location and climate as well as the condition of your existing roof. Ice and water shield is usually used in areas where there is high chance of snow, ice and freezing temperatures, and where there is a likelihood for a leak.
It is also used in areas with low-pitched roofs and areas prone to heavy rainstorms and high winds.
If you live in an area with any of these conditions, then it’s probably a good idea to use ice and water shield on your entire roof. When properly installed, it acts as a barrier that can help prevent water and moisture penetration that can cause serious damage over time to your roof and the interior of your home.
Ice and water shield also provides an extra layer of protection in preventing roof blow-offs, which can be caused during severe storms.
If your roof is in good condition and is not in an area that is prone to severe weather, then you may not need to use ice and water shield on your entire roof. You also need to consider the cost associated with installing ice and water shield.
It is an additional expense that you would need to factor into the cost of replacing your roof. If you do decide to use ice and water shield, you should make sure that the installation is done properly and that the product is applied to the entire roof for maximum protection and longevity.
How do I know if my roof has ice and water shield?
The best way to determine if your roof has ice and water shield is to have a professional roofer come and inspect your roof. A roofer will be able to identify if your roof has been installed with this type of material, and advise you on additional steps that may need to be taken if it is not already installed.
Generally, if a roofer recommends having ice and water shield installed, it is because they noticed that the shingles are not providing sufficient protection against water buildup. To check the installation and verify that all of the necessary components have been included, it is recommended that the roofer inspect all materials and equipment used in the installation process.
Additionally, the roofer should check that all of the necessary components, such as nails, flashing, and sealant, are intact and of good quality. Ice and water shield should be replaced at least every decade.
If you do not know when it was last installed, you may need to have a professional come in and assess your roof.
How long can grace ice and water shield be exposed?
Grace Ice & Water Shield can be exposed for up to six months without compromising its adhesion and performance. This is under normal weather conditions with temperatures no lower than 15°F and protected from direct sunlight and ultraviolet rays.

Does drip edge go on before ice and water shield?
Yes, drip edge should be installed before ice and water shield. Drip edge, also known as roof or eave edge, is a metal flashing material typically made of aluminum or galvanized steel. It is typically installed at the edges of the roof’s overhang to prevent water from spilling onto the fascia board and behind the siding of the home.
Installing drip edge before ice and water shield creates a more secure system to ensure that the roofing is fully protected. In addition, not only does the drip edge help protect the roof, but it also creates a finished edge that is aesthetically pleasing.
Proper installation of the drip edge must be followed to ensure water diversion and also promote a finished look.
How much should ice and water shield overlap?
When installing ice and water shield, proper overlap is essential to ensure adequate coverage of the entire roof surface, which should extend up the roof slope and down the eaves, corners, and valleys.
Generally, the overlap should be at least 6 inches both horizontally and vertically; however, it is important to consult local building codes prior to installation, as specific requirements related to overlap and other installation requirements may vary by area.
Furthermore, it is important to ensure that all seams of the shield are properly sealed. Ultimately, overlapping can help to prevent any leakage issues and ensure that the roof is properly sealed and protected.
