Roof Truss Varieties

There are many common roof truss designs which will suit nearly all roofing projects. Occasionally a highly specialised roof will require a custom design and this will be reflected in the roof truss prices. The triangular shape is extremely strong and effective at transferring any stress throughout the structure to the walls on which the trusses rest. This design has many advantages over using flat roofing. The triangular shape of a pitched roof is structurally far stronger than one which is flat or nearly flat. The risk of damage or collapse due to heavy rain or snow fall is reduced to almost zero as the shape lets excess water escape efficiently rather than accumulate on the roof.

Timber roof trusses are common in all types of properties with pitched roofs. They provide a solid structural framework while the truss is protected from the elements by the roofing materials it supports. This prevents any damage to the wooden structure. Steel roof trusses will also sometimes be used which are as strong as a timber frame. Commercial roofing projects are more likely to use steel roof truss plans than residential ones in conjunction with the metal roofing often used in commercial or industrial properties. This is partly due to the size of these buildings being considerably larger meaning metal roofing will be more suitable.

Roof Truss Failure

Although expert roof truss design ensures that they are very strong structures a truss can fail on rare occasions. This is most common in older buildings. Building roof trusses is a complex skill which is usually only undertaken by experienced professionals and any failure will rarely be due to mistakes made during roof truss construction. It will sometimes be caused by careless workmen drilling or cutting into them while working on electrical, heating or other systems and not understanding the structural important of the truss and the stress it is under.

The most common causes of wood roof truss failure are snow and more frequently, water damage. Water leaks resulting from rainfall or melting snow can cause damp conditions which will over time penetrate into timber roof trusses. This can also affect timber which has been treated, but not right the way through the wood. Damp will often cause timber to rot and may encourage insects into the wood roof trusses which will lead to further damage and weakening of the structure. These problems will be more severe in older roof trusses where wooden pegs have been used to fix individual parts together rather than screws, nails and glue as used in more modern buildings. Where the wooden pegs are damaged the joints can eventually fail which result in serious structural damage to the roof and maybe a total collapse. Where roof truss damage has occurred it can sometimes be remedied without dismantling the roof. Roof truss repair can however be very dangerous due to the weight of the roof being supported by a weakened structure. An experienced structural engineer should assess the damage before you decide to take any actions to repair roof truss rot problems or replace a roof truss.

Roof trusses are an essential component in virtually all roofing systems. Providing a solid framework which will support other roofing materials while at the same time spreading their weight, the truss will provide stability and security to the whole roof. They have proved extremely useful for many years and will continue to do so in the future.

Applications

Steel roofs are proving to be popular choices for owners of both commercial and residential properties. The wide range of styles and colours now available make steel roofing materials a legitimate option for property owners in any location and with any price range. A steel roof can be made to order with each roof designed specifically for the individual property it will be installed in. Many commercial and industrial buildings make use of steel roofing materials due to their versatility, durability and resistance to fire and corrosion. A corrugated steel roof can often be seen in factories, offices and large agricultural buildings. Often the whole roofing system will be produced from metal including supporting beams and steel roof trusses.

In the past people have been hesitant about choosing steel roof sheets over some of the other options available due to the way they look, particularly on residential properties. The current range on offer means this concern is no longer valid and makes many kinds of metal roofs attractive to a much larger pool of potential customers. Steel roof tiles are now available along with large sheets which are designed to have the appearance of individual tiles and are particularly popular especially for private homeowners. They have all of the benefits of steel roofing systems but with the visual appeal of tiling. Because of the range of suppliers now in the market and the ability to order materials easily online steel roofing prices are also now very reasonable.

Advantages

All steel roofing options are safe and secure. They also have a lightweight design making them easy to transport and install. Steel roofing sheets have a particularly good strength to weight ratio making them extremely useful in some of the largest roofing projects that cover huge commercial and industrial properties. The strength of the materials makes them very effective at resisting wind and hail even where the very sheets are used. Corrugated steel roofing is particularly strong as the metal is strengthened in the corrugation process. This helps to increase the bending strength in directions parallel to the corrugations. Like all metal roofing materials steel has the highest levels of resistance to fire and sparks making it particularly desirable in environments where fire risks would perhaps be higher than normal.

Many steel roof panels have surfaces which are effective at shedding snow especially where the roofs are painted. This is obviously a huge benefit in areas which experience heavy snow fall. A small temperature rise will be all that is necessary to ensure that the snow is quickly removed. Cool-roof paints can also be used in areas which experience high temperatures to keep the building cooler. The surfaces of these roofs will often also have high levels of solar reflectivity which restricts the amount of the sun’s heat which is absorbed by a building.

Steel roofing panels are extremely durable and can often be found with lifetime guarantees. Stainless steel is naturally durable and other types of steel roof sheeting can be treated to give them the same long lifetimes but at lower costs. This is achieved with the use of zinc and aluminium which will oxidise and form a protective coating over the base metal. These metals often provide protection from the elements to increase the life expectancy of a galvanized steel roof. Because of the high levels of durability which steel roofing can offer it will typically require very low levels of maintenance when compared with other popular roofing materials. This means that it is generally a good long term investment.

If you live in the US there are further benefits to choosing a steel roof. It is possible to receive tax deductions because of the energy efficiency of metal roofing. The materials used will generally be highly reflective meaning that the costs of cooling a home with a steel roof are reduced due to the lack of sunlight being absorbed. This of course means less energy is consumed by the household.
