Roofing Sheets Perfect for Verandas

A veranda is a versatile outdoor space; it’s perfect for outdoor entertaining, relaxing, teatime, and all sorts of activities that are made more delightful by being carried out outdoors. This outdoor space is more useful if it has a durable cover that can shield furniture and people from weather elements. And speaking of such features, roofing sheets remain the most popular material, even if many are charmed by other options like retractable wave shades, sheer drapes, and tiles. If you need some ideas on what roofing sheets would be nice to use for your veranda, provided below are four examples: Flat and clear polycarbonate panels – Many love the sophisticated appearance of these roofing sheets because they make the veranda look like a delicate glasshouse. Illumination is never a problem if you go with this option. Likewise, you can enhance the look of these roofing sheets in a variety of ways. But perhaps, the coolest advantage you can get from these polycarbonate panels is the way you get a clear view of the sky while still remaining protected from natural elements like rain or snow – it’s a wonderful “inside-outside” experience. Translucent polycarbonate sheets – These come in a large variety of colours that can pop or blend with the colour scheme of your home. The nice thing about these roofing sheets is that they do let sunlight through but you won’t have to squint because it’s too bright. It’s worth pointing out as well that these are resistant to heat, snow, and rain – they are virtually unbreakable; therefore, they will last you many, many years. These are a little pricey though, so find a good vendor that offers them at discounted prices. Corrugated iron – Untreated corrugated iron is quite popular because of its rustic appeal. Also, it’s among the cheapest options for roofing sheets. They get really hot, however, so perhaps they’re more suitable for areas that don’t get much sunlight. If you would like your veranda to have a strong country charm, corrugated iron is a great choice — it will also look even more charming as it “ages.” White Colorbond roofing sheets – Apart from their neat appearance, white Colorbond roofing sheets provide the advantage of helping keep verandas cool on a hot day. Compared to other colours, white doesn’t absorb as much heat and it creates a more comfortable temperature in the space underneath it. Plus, it’s a nice colour to work with if you have all sorts of creative ideas to make your veranda truly visually appealing.

5 Ways to Prolong the Life of Your Corrugated Iron Roof

Roofs are not easily visible to the homeowners' eyes from where they stand, so it can take some time before they notice that the metal sheets require repair or replacement. Since roofs take a significant beating from the elements day in and day out, they can be expected to exhibit wear and tear after several months or years. It's important to subject the roof to regular inspections and maintenance measures to ensure that it is kept in good condition, and that your home stays well-protected. Here are some valuable care and maintenance tips that you can follow to prolong the life of your corrugated iron roof: Perform regular cleaning. This is perhaps the simplest way you can extend the life of metal roofing sheets. Perform routine cleaning so you can remove branches, leaves, stones, twigs, bird droppings, old nails and pieces of timber; leaving them lying on the roof leads to the creation of crevices and accelerated loss of coating in the areas between the debris and the roof. Keep the roof secure. Loose fixings may be further loosened by hard wind and rain. Make sure all sheets are screwed down. Replacing damaged sheets. If a roofing sheet is beyond saving with simple maintenance procedures, a replacement will be necessary. You need to consider factors like colour, materials, sheet length, profile, fastenings, and the availability and compatibility of materials to ensure that the replacement sheet is functional as well as a good match to the appearance of the original roof. You can consult your local roofing specialists about how well top brands like Colorbond and Zincalume sheets will work with your original roof and design scheme. Colorbond sheets, for example, are a good match if they will be used to replace an unpainted zinc roof (Zincalume may be too glossy to be a good match, and is not compatible with traditional lead flashings as corrosion will ensue when the two materials are combined). On the other hand, if you will be replacing everything (roofing sheets, gutters and downpipes), it's a good idea to use COLORBOND® for all of these roofing features for excellent performance.

The Ultimate Colorbond Roofing Technique to Help You Save More on Energy Bills

Keeping your home cool during summer and warm during winter does not solely depend on your HVAC systems. Your home’s roofing techniques also matter greatly when it comes to maintaining the temperature within your house. For many years, metal roofing has been offering home owners great benefits not only in terms of durability, but also when it comes to ease of installation and maintenance, fire-resistance and energy efficiency. While they may cost relatively more than other roofing materials, their advantages are incomparable. Metal roofs are so durable that they can last for 60 years or much longer with proper maintenance. Because of this, they also increase the value of your property. Metal roofs, such as Colorbond roofing offered by a trusted Australian bluescope steel supplier, make your home energy-efficient. Over the long term, you’ll be surprised by the amount of money you can save on energy bills. To help you reduce your energy consumption, metal roofs must be installed correctly. It is very crucial to secure the services of professionals to ensure proper implementation of roofing techniques like sarking or aluminum reflective roofing foil insulation. Sarking of metal roofs While Colorbond roofing provides protection against condensation, roofing professionals who have been in the metal roof industry for decades will tell you that the installation of a roof blanket or foil provides additional protection against heat and sound.  There are various techniques for roof insulation. Seasoned roofers these days recommend the reflective insulation or Sisalation, which has been known to provide savings on energy bills by as much as 25 percent. Unlike common types of insulation that either resist or slow down heat, reflective insulation reflects heat. This technique uses a thin blanket of aluminum and plastic substrate that allows the reflection of heat by as much as 97 percent and therefore prevents it from moving to other parts of the home such as walls and cracks. More appealing benefits of reflective insulation First, Sisalation roofing foil is generally much easier to install because it is lightweight. You can simply staple, glue or nail it onto the roof battens. Second, it effectively provides a barrier against moisture and humidity since it prevents condensation on the underside of the roof sheet. Third, it enhances a healthy atmosphere within your home as it inhibits the growth of moulds, fungi, and mildew. Fourth, this material is not suitable as a nesting ground for unwanted pests. This means you’ll have peace of mind dealing with insects and rodents and even birds that might nest on your roof. Finally, it is safe to use. The material is non-toxic and approved for use in homes with asthmatic residents.
