Roofing is a vital element of building homes because most properties require something to provide shelter. Inevitably, roofing has advanced over time and, in particular, during the past twenty years. With the increased number of homes being constructed, more roofing options have become available. This satisfies both functional and aesthetic requirements. It’s incredible to see the number of choices homeowners have with regards to roofing. Here are some of the main types to be aware of:
Undoubtedly, built-up roofs are regarded as a traditional roofing option. Devised more than 100 years ago, this roof type has stood the test of time — so it is a popular choice with many property builders. A built-up roof is not without its flaws because it can present some notable restrictions; however, many people who opt for this type are happy with their decision.
Typically, built-up roofs are used in high footfall areas and when the roof could suffer mechanical abuse. The membranes on these roofs are stronger and thicker than many other roof types. Both gravel surfacing and multiple layers are included. Due to this option’s popularity, it is normally simple to find roofers who can install and fix a built-up roof in most cities.
The primary drawback with a built-up roof is its inflexible nature. The roof might get damaged because of thermal or structural movement. Long buildings would require extra roofing support to stop contraction from harming the roof. Stretching because of warm temperatures or compression because of cool temperatures might also wear out a built-up roof. Maintenance is required if these issues are evident in a specific area.
A Modified Bitumen Roof
These types of roofs offer similar benefits and drawbacks as built-up roofs. Nonetheless, one distinct benefit of modified bitumen roofs is that they perform considerably better when cold. This roof type is designed to turn flexible if the temperature drops. It can withstand changes to the temperature better than built-up roofs.
Modified bitumen roofs come in a couple of types – the rubber-based models (SBS and SEBS) and the models based on plastic (APP). Typically, plastic-based membranes are fitted using torches, whereas the rubber membranes are fitted using hot asphalt or cold adhesives. The majority of these roofs have granulated surfaces already. This means that they weigh less than a built-up roof with a gravel surface. Besides, modified bitumen roofs might be used as cap sheets for older built-up roofs. This makes the roof tougher and more flexible.
A Single Ply Roofing System
As the name implies, a single-ply roof consists of one layer made from elastic or plastic material.Because there is just a single layer, this kind ofroofing is dense. Single-ply roofs are available in two categories: thermoplastic membranes, which have seams that are welded with a solvent or heat; and thermoset membranes, which have seams sealed with adhesives. The three kinds of single-ply attachments are loose laid, fully adhered, and ballasted. Thanks to their lightweight properties, single ply roofs are good for recovering. Also, they are reasonably affordable.Some single-ply roofs are sensitive to specific substances, so take care when selecting from different types of single-ply. PVC and EPDM-based materials might be harmed if exposed to jet fuel, cooking grease or oil. If emissions of this nature are prevalent in the neighborhood.
Metallic roofs are no longer restricted to flimsy sliding panels that are fitted insecurely, then nailed or screwed onto a frame. These days, there are metallic roofs with concealed clips that are secure. These clips can be contracted or expanded. Possibly the most vital consideration, when selecting a metallic roof, is its lifespan: metal will not deteriorate, even after exposure to severe weather conditions. Some metallic roofs might have fifty year warranties. The drawback with metal, though, is the increased likelihood of leaks in comparison to other types of roofs. Leaks are a common occurrence, if metal is installed incorrectly.
