Sarasota Roofer Tackles Flat Roofing Systems

By Patricia Mathers


Flat roofing systems offered by your Sarasota Roofer Mark Kaufman Roofing Contractor, Inc. range from simple to complicated according to the type of building as well as the desire of the client. A simple roof will comprise of a cover being placed on bare joists while with complicated types there will be additional layers such as isolation. Isolation is meant for energy control inside the building in which the roof is fixed.

When designing a roof, a roofing contractor will always put into consideration the effect of heat changes on the materials they intend to use. This means that there are materials that will be preferred in one geographical region than others. In case the designer fails to cater for thermal expansion and contraction in his design, the roof will be subject to damages caused by fracturing.

In contrary to what the name suggests, flat systems do not have a zero slope or no pitch. In real situations, a slight incline will be applied so that water can fall off the roof through gravity forces. The inclination is small for continuous materials but more significant in jointed materials as they need to to lose water quickly to avoid penetration.

Metallic covers are the ones used if durability is needed. One of the metals used includes zinc which can form very complex profiles as it is durable as well as has good properties of ductility and malleability. However, these advantages will only be realized if the design and implementation work is done by a qualified professional. If this is not done, the materials will rumple during hot weather leaving crevices and consequently result to leakages. During the first rainfall, Lead will react with water forming its carbonates and sulfates which do not dissolve in water. This means that there will no be any further corrosion after that thus increased durability.

Copper is another metal that is also used in this purpose though a few contractors prefer it as it is slightly expensive as compared to the others. Due to availability and durability, a steel roof will cut down the overall cost of fitting the shelter. If zinc is used, the underside should be treated with a non corrosive material to do away with corrosion.

Today, continuous covers are being applied by many people as they are cheaper and stylish. Since the materials used can comfortably adjust to frequent thermal expansion and contraction, they can be laid with no need of joints. Although such materials may not be susceptible to corrosion, they become brittle with time as their elasticity ability fades away.These materials are very convenient in achieving short term roofing needs and in situation where quick roofing is required.

Before the innovation of synthetic polymers, rock asphalts were the ones used for constructing roofs. This was replaced by bitumen combined with limestone particles. Further improvement involved adding synthetic polymer to the adhesive before adding crushed limestone. Guarding a membrane from high temperatures through a reflective coating will prolong its life to a large extent.

With the increased need of a material that can easily be tailored to fit in buildings of different shapes, single layered synthetic membranes have gained popularity as they have this capability. Flat roofing systems are done in accordance with the building standards provided in the construction guide. They ensure the materials used to attain the minimum standard as per international codes to enhance safety of those utilizing such structures.
