Metal roofing for residential buildings is a fast-growing phenomenon, and many homeowners are actually removing their old roofing and installing metal roofs. Some even take this step before their previous roof has worn out.
Trends like this point to the superiority of a metal roof. The newer products last longer, cost less and are easier to install than their predecessors. They’re also a greener alternative to more traditional roofing materials. With that in mind, have a look at some of the specific advantages that metal roofs are offering homeowners in the 21st century.
Other roofing media, such as asphalt, need to be replaced or substantially remodelled every 15 to 20 years. That may seem like a long time, but when you are dealing with a home that you plan to live in or eventually sell, that’s not very long. Wood shingles dry out, curl or even crack. Most roofing materials begin to deteriorate as soon as you have installed them. Constant exposure to the strong ultraviolet rays of the sun takes its toll – and that’s just the beginning. Wind, rain, hail, freezing and thawing and a host of other natural elements bombard your roof day in and day out. However, metal roofing maintains its appearance over the long haul and continues too to do its job several years after you have installed it.
Another strong advantage of metal roofing is that it can be coated with highly durable materials that both enhance its appearance and extend its life. The metal base is sprayed with an alloy undercoating that increases its strength. On top of this, an acrylic primer is added, followed by base coats and bonding agents. The outer coat completes the roofs aesthetic appeal. The final product is a roof that is resistant to chalking and unlikely to fade. These protective and attractive coats allow roofing companies to guarantee their products for up to 50 years.
Fire and wind resistance
Breakthroughs in roofing technology have produced advanced materials that are much safer than the previous generation of metal roofs. Alroy sheet metals do not disintegrate or rust in the rain, and if lightning strikes, they disperse the charge rather than catching fire. Furthermore, strong winds and severe storms are much less likely to rip the roof from the house.
This is a more important consideration than ever before for more reasons than one. To begin, many homeowners are increasingly conscious of how much energy they consume. They want their homes to be green and eco-friendly. Furthermore, rising energy costs mean that any effort to reduce the amount of money that it costs to operate a house is well appreciated. The colour of the roof affects the amount of heat that a home absorbs, but the difference comes down to more than just hues and pigments. New roofing technology has given us reflective technology that dispels heat. Roofs made of recycled post-consumer products or equipped with solar cells complete this consideration.
The newer generation of metals used in modern roofing projects are very low weight, and this is going to save money in a variety of ways. To begin with, the cost of shipping the materials to warehouses, distributors and – ultimately – to your costs less, and this produces savings that can be passed on to the end user. Beyond this, decreasing the weight of roofing materials has made them easier to work with, such that install teams do not need to have as many people working on site, nor must they work for as long.
