Advantages and disadvantages of bituminous tiles, soft roofs.

Bituminous (flexible) shingles are the ideal roofing material that has proven its reliability. But when installing this type of roof, certain difficulties may arise. Let’s take a closer look at the advantages and disadvantages of a soft roof.

Features, advantages and disadvantages of shingles.

bituminous shingles guarantee water resistance with a roof slope of 12 degrees, this rule must be observed because otherwise, your roof may leak; the presence of a solid base in the form of a moisture-resistant osb plate is mandatory. This entails the need to purchase additional materials, which increases the cost of the roof; if the roof slope is up to 18 degrees, an additional underlay will be required. It plays the moisture-protective role of the roof – its problem areas: the joints of the osb plate and the roof ribs, which will also affect the cost, this is a requirement of many manufacturers Katepal, Owens Corning; the difficulty of carrying out a partial replacement of the soft roof on your own, since the sheets of smooth tiles are glued together and form a continuous surface. In this case, you cannot do without the help of a specialist; the high cost of shingles, which exceeds the cost of metal tiles, bituminous slate and is practically comparable to cement tiles or inexpensive ceramic tiles, especially if we take into account the cost of the OSB-3 slab and underlay. when the sun is strong, the bituminous shingles heats up and softens, therefore it is not recommended to install these shingles at lunchtime or simply move along the already laid roof.

Morning and evening hours are best suited for this. in winter, bium shingles become fragile, therefore, immediately before installation, it is recommended to hold the shingles in a heated room. More details can be found in the article

installation of bituminous tiles in winter. the weight of the bituminous tile together with the OSB-3 board and the underlay is 15-20 kg / m2. In fact, this is not a disadvantage, but 20 kg / m2 square already requires a calculation and a balanced approach to the installation of the rafter system https://ru.life-hacks.fun/page-7-voprosov-kotorye-nikogda-ne-sleduet-zadavat-sebe-i-chto-luchshe-zadat-chtoby-dobit-sia-uspekha-v-zhizni. fire resistance – there are many opinions on this topic, but we can confidently say that high-quality flexible tiles are fire resistant, do not support combustion and are difficult to ignite.

What problems were encountered with a soft roof in practice.

Soft roof installation technology.

An important point when laying shingles is compliance with all aspects of the technological process. Also, when working, there must be increased accuracy and caution. Compliance with all laying rules will avoid deformation of the sheets.

Otherwise, the waterproofing and integrity of the roof may suffer even under the influence of atmospheric influences, strong winds, as well. To avoid undesirable consequences, it is also necessary to install a high-quality crate for this type of coverage.

Roof ventilation should be provided under the soft tile roof. Otherwise, the formation of a greenhouse effect and condensation is inevitable, which can cause the formation and development of fungal mold and rotting of wooden roof structures.

But one cannot ignore the fact that bituminous shingles are the best suited for roofs with complex structures. Moreover, considering its price range. In addition, a shingle roof looks much better than a metal sheathed roof.
