Choosing just the right way to cover and shelter the building your livelihood operates from can mean the difference between high efficiency, and stagnation. Therefore, it is imperative to choose the right option for commercial roofing in Surrey for you. Getting someone to install a roof for your business can mean the difference between great protection, and absolute disaster. Calling a commercial roofing Surrey contractor to do an evaluation may seem like the obvious choice, but it always pays to be informed of what options exist, having a clear idea of what you have in mind, and knowing what will be a better choice for your unique needs, before calling the first and best contractor. Contractors are experts in their department, but they will usually try to promote the roofs they can install for you, rather than giving a larger option of suggestions (most contractors are only familiar with the roofing options they themselves offer). Therefore, after reading this article, we hope that you are better informed and able to call a roofing contractor with an idea of what you want already in your mind.
In part one of this article, we discussed the most common options for commercial roofing; like TPO & PVC, EPDM, Green Roofing and Photovoltaic Solar Panels for steeped roofing options. In part 2, we will be building on our options, with a look at how flat roofing options compare to steeped roofing options.
Flat roofs are an ancient style dating back to pre-Egyptian eras. It is a wonderful way of maximizing space, as opposed to roofs which have a pitch or a slope to them. Having a flat roof provides the opportunity for further activity. Traditionally, flat roofs are used as added living space for home designs. In commercial buildings, a flat roof can provide the opportunity to create the space for a helipad, outdoor restaurant seating, sports facilities or swimming facilities, as many hotels do, as well as creating the opportunity for a living roof, a roof containing grass or other growing, living plant matter. This would create a wonderful opportunity for a commercial business to supply an urban area the chance to sustain some wildlife while offering the building insulation, and the chance to utilize rainwater harvesting techniques.
Flat roofs should only be considered for use in countries which are not susceptible to extremely cold weather conditions, due to blowing, a condition in which rainfall during cold conditions can lead to ice forming and expanding within the cracks and crevices of the bricks and mortar and then expanding, leading to the cracking of the structure.
Flat roofs are extremely cost effective, especially because their surface area is smaller than sloped roofs. They are also said to be stronger, and long lasting, generally seeing the 10-year mark provided they are well maintained and depending on the quality of the materials used, and the type of materials used. A flat roof can be constructed using the same methods or materials previously discussed in part 1 of this piece; such as TPO & PVC, and EPDM.
Maintaining a flat roof can be somewhat more laborious than the maintenance associated with a steeped roof, however, this is no reason to feel deterred at all. It is important to remedy ponding within 48 hours (or as soon as possible). This is not done manually but rather implemented during the design phase of the roof installation, using a timer and a check valve or an automatic syphon. It is imperative that the roofing contractor implements automatic systems to drain water periodically through cloudbursts or prolonged wet conditions as typically seen here in Surrey, BC!
Keeping the drainage systems clear is also a vital part of flat roof maintenance to allow for proper drainage. Pay special attentions to corners in the piping, as debris can easily become lodged here, leading to pooling of water on the roof.
Delamination occurs in the form of blisters, which can retain moisture within the little pocket, and this will eventually become a leak. A blister will need to be cleared and sealed before being repaired.
The efficacy and overall life of a roof can be greatly extended and improved by the regular use of roof coating. While protecting the roof from ultraviolet damage through the sun, it also provides a watertight seal that is neat, and completely seamless.
Ensure that your choice of roofing contractor makes use of infrared thermography during maintenance calls, as this will help to locate trouble areas in the roof with far greater accuracy, often pointing out weaknesses before they even become a problem. It works by finding wet spots which are not visible, but busy in the process of evaporation and therefore creating heat. These are indicators of leaks forming.
Any decent contractor should offer a potential client a variety of options, in both steeped and flat roofs for commercial buildings. For more information, feel free to contact a roofing contractor in Surrey, and compare quotes and services to find the best solution for your business!
