Types of soft roofs and their cost

How much you have to pay for a soft roof depends on the type of material.

Roll material

Roof roll material is a kind of carpet formed from extra strong fiberglass, improved bitumen, an adhesive layer and painted decorative stones. The web from the roll is spread in several layers and adhered to the roof surface using a gas burner.

Roll material for roofing is the choice of those who want to protect the roof from moisture and save money

Roll material is known for the following positive characteristics:

• inaccessibility to moisture;
• fearless contact with low temperatures;
• affordable price;
• elementary installation instructions.

Despite all the advantages, soft carpet tends to tear, which means that it will constantly need to be repaired.

Table: cost of grades of roll material

Roof roll grade	Price for 1 m²
Technoelast	From 100 rubles.
"Uniflex"	From 93 rub.
Ekoflex	From 70 rubles.
"Bipol"	From 67 rub.
"Linocrom"	From 64 rub.

Roof membrane

The roofing membrane is most often a polyvinyl chloride sheet with an admixture of high volatility plasticizers. It is PVC membranes that have a reputation for being the most plastic material, because they are born in an unusual way - by welding polyvinyl chloride with a stream of heated air.

Membrane roofing is much more perfect than a conventional roll roof

The demand for roofing membrane is quite high due to the following advantages:

• unsurpassed elasticity;
• resistance to sunlight;
• immunity to ultraviolet light;
• wide range of colors;
• tolerance of atmospheric precipitation and sudden temperature changes.

The negative characteristics of a roofing membrane are called:

• the ability of an unnatural canvas to harm human health;
• incompatibility with materials mainly consisting of bitumen.

Table: overview of prices for roofing membranes

Roof membrane brand	Price for 1 m²
"Elon Super"	Within 500 rubles.
"Decopran E-A"	Up to 300 rubles.
"Krovlelon E-A"	About 300 rubles.
Alkorplan 35276	Within 500 rubles.
Ogneizol-TPA-1	About 200 rubles.

EPDM membrane

EPDM membrane (membrane of ethylene propylene diene monomer) is a separate type of film material, a web of complex structure. It consists of synthetic rubber, fiberglass, which ensures the connection of all layers of the material into a single whole, and a mixture of polymers with bitumen, which is responsible for the plasticity of construction materials.

The EPDM membrane is devoid of serious drawbacks, although it is expensive

The EPDM membrane has gained increased interest due to its advantages such as:

• installation with a small number of seams;
• excellent durability (due to synthetic rubber in the composition);
• long service life without frequent repairs;
• "Painless contact" with rain and snow;
• the ability to maintain its shape;
• protection from moisture penetration.

There are no serious defects in the ethylene propylene diene monomer membrane.

Table: how much does an EPDM membrane cost

EPDM membrane brand	Cost of 1 m²
Giscolene	More than 300 rubles.
"Elastosil T"	Within 1500 rubles.
"Aqualasten-E"	About RUB 100 / piece
"Elon"	About RUB 100 / piece
EPDMPROOF	From 300 rubles.
OVOPROOF DA-K	From 400 rubles.

Thermoplastic polyolifin

Thermoplastic polyolifin (TPO) is a membrane, the main components of which are organic compounds derived from petroleum and reinforced with glass fiber or polyester. A welding machine is used to mount the thermoplastic polyolifin to the roof.

TPO membrane is a relatively new material for roofing

A positive opinion about the TPO membrane was formed by such characteristics as:

• relative safety (does not emit volatile compounds into the air);
• preservation of appearance and qualities, despite exposure to extreme cold (up to -62 ° C);
• good elasticity (slightly worse than EPDM and PVC membranes);
• excellent strength that does not allow the material to deform;
• inaccessibility to fungus and mold.

Table: overview of prices for TPO membranes

Product brand	Price for 1 m²
Firestone	From 580 rub.
Bauder Thermofin F 12	From 500 rubles.
Bauder Thermofin FTL 15	From 650 rub.

Bituminous shingles

Bitumen shingles are almost no different from roll roofing, but the first is slightly thicker.

Bituminous shingles look interesting and do their job well as a roofing material

The advantages of shingles are called:

• ease of styling;
• variety of shapes and colors;
• heat preservation;
• protection from rust and decay;
• the ability to imitate natural tiles;
• inaccessibility to moisture;
• blocking noise.

The disadvantages of shingles are:

• fear of high temperatures;
• complex repair.

What you need to consider in order not to pay extra for the roof

So that the cost of installation work does not cause confusion or even indignation, you need to know exactly what you have to pay for.

How much the master will ask for the installation of a soft roof depends on the following factors:

• roof area;
• form (simple or complex);
• the scale of construction (replacement of the old coating or installation work on the roof of a new building);
• the integrity of the roof (absence or presence of cracks);
• the need for additional work (for example, priming or screed) and installation of additional elements or systems.

Last but not least, the reputation of the construction company affects the cost of work. To be sure that the prices for the company's services are not overpriced, it is necessary to find customer reviews, or even better, to look with your own eyes at the roof created by the efforts of this company.

Correct calculation of the cost of installing a soft roof

A real example will help you understand how to correctly calculate the costs of installing a soft roof.

When calculating the cost of installing a soft gable roof with a slope of 25 ° for a house measuring 6 × 6 m, the following actions are performed:

1. It is established that the length of each roof slope is 6 meters.
2. Find the length of the rafter, that is, ½ the width of the house divided by cos (25), add it to the length of the roof overhang (0.3 m) and multiply by the number of slopes.
3. The resulting value of the length of the rafter is multiplied by the length of the ramp and rounded off, resulting in the roof area (44 m²).
4. The roof area is divided by the useful area of the web in a roll (or one strip of membrane roofing) - the amount of material is found out. To determine the cost of purchasing it, the resulting figure is increased by 10% (it will go to waste) and multiplied by the price of one roll of roofing material.
5. The length and number of additional elements are taken into account. Take a ridge bar 6 m long, two cornice elements 6 m long, valleys and end strips equal to the length of the rafter leg multiplied by 4. Do not forget about the abutment - the pipe perimeter is added with the size of the overlaps. Each figure obtained for a specific element is multiplied by its value. After that, all the "nodes" are summed up.
6. Consider in detail the rafter system. First of all, taking into account the length of the step (0.6 m), determine the number of rafter legs (6 / 0.6 + 1) x 2 = 22), and then find the total length of the rafter bar, that is, the number of rafters is multiplied by their length (22 x 3.7 m = 80.7 m). The length of the mauerlat beams (6 x 4 = 24 m) and the ridge (6 m) are added to the calculated meters and 130.7 m are obtained.
7. Focusing on the cost of one timber, determine the amount required to purchase a batch of material. They also calculate how much finance is needed to purchase auxiliary elements (racks, struts, etc.).
8. It is established that the total length of the element of the plank base for the roofing material is 6 m. The distance between the boards is chosen depending on the type of roof finish and is adjusted to the format of the plates of the insulating material. To find out the number of pieces of insulation, the number of gaps between the rafter legs is multiplied by the number of plates in height. The length of the rafter is taken as the length of the counter beam.
9. Based on the parameters of the roof slopes, the costs of snow traps and pipes for rainwater drainage are determined.
10. All the numbers obtained are summed up. To them is added the cost of installation work and delivery of material to the construction site.

Knowing in advance how much you have to pay for a soft roof, you can be calm. To make an estimate on your own, you need to have an idea of the prices for the material, the complexity and volume of installation work.
