Roof pie under the soft tile

One of the most important parts of your house is the roof, which keeps you safe from the weather and guarantees the structural integrity of the building. Because of their adaptability, toughness, and visual appeal, soft tiles are becoming a preferred choice when it comes to roofing materials. Still, the tiles alone won’t guarantee the success of your roofing project. The "roof pie," or what lies beneath them, is equally important.

The roof pie under soft tiles is made up of several layers, each of which has a distinct function to guarantee proper roof function and a long lifespan. These layers are crucial to the overall functionality of your roof because they cooperate to offer structural support, insulation, and waterproofing. When installing or renovating, knowing these layers and how they work will help you make wise decisions.

Understanding the roof pie beneath soft tiles will equip you with the knowledge required to create a sturdy and dependable roofing system, regardless of whether you’re building a new home or renovating your old one. This post will walk you through the key elements of the roof pie, outlining the function of each layer and why it’s necessary for a roof to be installed successfully.

Roofing pie under the soft roof

This term describes the layout of the soft roof, which occupies the space inside the rafter frame and between the roof’s outer and inner faces. It is made up of layers made of different materials, each of which serves a purpose. The design’s name is akin to the name of the culinary product because of its layers.

The addition of soft tiles to the roof enhances its waterproofing qualities and offers insulation. Each of these roles is handled by a different layer; for instance, a waterproofing layer is added to the pie to improve its resistance to moisture. Depending on the type of roof, the pie’s component count varies; for example, insulated roofs call for applying more layers.

Let’s take a closer look at the soft tile roofing plan now.

A sturdy and functional roof depends on building a solid roof pie beneath soft tiles. Together, the components of this layered structure—which include ventilation, underlayment, insulation, and decking—avoid leaks, weather damage, and energy loss in your house. Every layer is essential to maintaining the roof’s longevity and functionality, so it’s critical to comprehend and install each component correctly. Your roof pie can offer outstanding protection and efficiency for many years to come with the correct materials and careful installation.

Pie for a cold roof

If the home’s owners do not plan to use the attic as a living space, there is no need to insulate the roof. Cold Roof Pie is made up of six layers with a comparatively straightforward structure:

• Tile covering.
• An underlayment that enhances the protective properties of tiles and acts as a waterproofing agent.
• OSB (oriented strand board) coating designed for use in high humidity environments.
• Lathing.
• Waterproofing.
• Rafter frame.

Unlike metal profiles, soft tiles need extra pads to secure and reinforce the coating’s position.

In order to stop condensation from forming inside the roof, waterproofing is required. It can be positioned both in front of and beneath the sheathing.

Thermal insulation of the roof becomes essential if you plan to use the attic space for either temporary or permanent residence (that is, to convert it into an attic space). The insulating layer makes the roofing pie thicker and makes installation more difficult. Installing a vapor barrier is another aspect of insulation that helps prevent the room’s materials from being harmed by internal condensation.

So, there are two more layers in the roofing pie for soft tiles. The finished design appears as follows:

• Tile covering.
• Underlay carpet.
• OSB coating.
• Lathing.
• Waterproofing.
• Thermal insulation.
• Rafters.
• Vapor barrier.

Pie with a soft roof and insulation

Unlike installing a metal tile roof, bitumen itself has good moisture-proofing qualities, so in this case, laying a separate waterproofing layer is not necessary. However, extra waterproofing will greatly increase the roof’s operational potential due to its high slope angle and insulation.

It’s crucial to allow for some natural ventilation between the layers when arranging the cake.

Waterproofing and vapor barrier

The waterproofing layer is only applied to the most vulnerable areas, such as the ridge, overhangs, valleys, and the areas surrounding pipes, if the angle of the roof slope is less than 18 degrees.

Waterproofing is applied to the whole roof area if the slope angle is greater than 18 degrees.

There are two types of moisture-proof materials: liquid and solid. The first ones are used on roofs that are flat or have a small inclination of up to 5%. Greater slopes on the roof call for the use of solid materials like rolls and film.

We will focus on hard waterproofing since soft tiles are typically installed on sloped roofs.

Waterproofing membranes are the best type of materials that resist moisture. Its pores are funnel-shaped with a narrowing on the upper edge rather than typical cylindrical shapes. This design keeps moisture out of the roof while allowing condensation to freely exit the interior.

1. If no special design solutions are conceived, then waterproofing is laid between the rafters and the sheathing. It is fixed to the rafters using a construction stapler, and it should be fastened to the sheathing with self-tapping screws.
2. Soft roof waterproofing is laid in the direction from eaves to ridge. The overlap between two sheets of material should not be more than 12 cm
3. The sheets are held together using adhesive tape.
4. The film or roll may sag in the space between the edges of the rafters, but no more than 20 mm. Such sagging will improve the ventilation capabilities of the roof.

Vapor barrier stops moisture from entering the house from the outside, as opposed to waterproofing, which shields the inside of the roofing material from moisture. Since protecting the insulation is its primary purpose, vapor barriers are rarely used on cold roofs.

You should choose a vapor barrier material carefully, taking into account that it will be subjected to insulation pressure when the roof is operating.

The most widely used materials for vapor barrier films are aluminum foil and polyethylene.

Putting a soft roof’s roof pie to waterproof it

With staples or galvanized nails, the film is fastened to the rafters. If any of the joints are not carefully connected, condensation may seep into the cake’s interior. Similar to installing waterproofing, a small amount of film sagging is required to enhance interior ventilation. However, sagging is unacceptable if a vapor barrier is installed in place of a film; the material needs to be tensioned.

Antiseptic impregnation is applied to the rafters prior to the installation of all insulating layers.

Insulation of flexible tiles

In addition to offering waterproofing and vapor resistance against moisture, the insulation material needs to have adequate water resistance to prevent even the smallest leakage of the protective layers from damaging it.

Additionally significant are standards like:

• Thermal conductivity. It should be as low as possible.
• Form stability. The material should not deform at the slightest impact.
• Low density. Heavy insulation will push through the rafters and vapor barrier.
• Resistance to temperature changes.
• Fire resistance.
• Environmental friendliness. If the attic is used as a living space, it is important to choose materials that do not emit toxins.
• Soundproofing. Soft tiles do not create as much noise as metal tiles, but noise protection is still an important parameter.

The most widely used insulation materials are glass wool, mineral wool, penoizol, polystyrene foam, and polyurethane foam. These materials stand out due to their affordability and resilience to adverse effects. However, it’s crucial to make sure they are adequately sealed off from the living area because some insulation materials, like glass wool, can cause harm to people due to their continuous infiltration into the body.

It is imperative to allow for the formation of gaps with vapor barriers and waterproofing prior to installing the insulation. This is required to guarantee ventilation and shield materials from harm when they rub against one another.

When insulating a soft roof, the steps involved are as follows:

1. Nails are driven into the lower edges of the rafters at all corners at equal distances from each other.
2. The thermal insulation material is slightly compressed and inserted into the space between the rafters.
3. The cords are threaded and secured between the driven nails in a crosswise position; they are the ones who make the insulation securely fastened.

Slatted wooden sheathing can be used in place of cords; it is attached in increments of 40 centimeters, parallel to one another rather than diagonally.

Tile insulation is applied by comparison with other coatings.

Typically, two layers of thermal insulation are installed. The materials need to be trimmed if the insulation blocks extend past the lower and upper planes of the rafters.

These constitute the soft tile roofing cake’s principal ingredients. The primary distinction is that the material used for this type of roof is well waterproof, negating the need for an additional moisture-proof layer to be installed. All other components that are required are the same as those for other tile types.

Layer	Description
Base Layer	Strong and flat base like plywood or OSB sheets to support the shingles
Underlayment	Waterproof layer to protect against moisture
Starter Shingles	First row of shingles installed at the eaves to ensure waterproofing
Shingles	Main roofing material providing protection and aesthetics
Ridge Cap	Special shingles installed along the roof ridge for additional protection

For soft tiles, the proper roof pie must be made in order to guarantee the durability and performance of your roof. This multi-layered roofing system offers a strong foundation, suitable insulation, and sufficient ventilation, all of which combine to shield your house from the weather. You can avoid common roofing issues like leaks, mold, and temperature fluctuations by carefully choosing and installing each layer.

Every part of the roof pie has an important function. While the underlayment adds an additional layer of moisture protection, the base layer offers structural support. In addition to saving energy and assisting with temperature regulation inside, insulation also adds strength and visual appeal to the finished soft tile layer. Your roof’s performance can change significantly if you pay attention to these details.

Maintaining the best possible condition of your roof also requires routine maintenance and inspections. Paying attention to small problems early on can save expensive repairs later on. Your roof will provide you with good service for many years if the right materials are used, installed correctly, and maintained. For any homeowner, making the time and effort to build a sturdy roof pie is a wise move.
