Propped up by the reliable tenets of good design in troubled times, roofing preferences are getting more sustainable in 2021. The search for smarter buildings begins at the roof, and it helps to know which way the wind is blowing, whether you’re building your home from scratch or giving it a face-lift.
Innovation has percolated into roofing materials and roofing design. Technology is allowing designers to auto-generate complex roof truss systems with roof framing modeling software, helping to cut costs and save labor. There’s a lot that can be achieved in your next residential renovation project by the melding of modern technology and evolving aesthetic trends.
With the world in a crisis, the eco-friendly theme is here to stay. What was strictly the domain of commercial buildings is now expanding its boundaries to let in residential players. We are speaking of the green roof, and placing a garden on the roof of your home has never been trendier.
The benefits of green roofs range from storm-water management, to improved air and water quality, from lower energy consumption to less noise. Green roofs extend the life of your roof and increase green spaces in the city, in a holistic view that’s good to take these days. Green roofs are likely to be the future of smart cities.
Along the same lines of sustainability, cool roofs are becoming increasingly popular in a heating world. These roofs are built with sun-reflecting and absorbing materials that will reflect heat or absorb it depending on the wavelength of the light. They bring down the heat transferred to the building to make cooler interiors.
The result is a home that can be more energy efficient. Power bills are going down and HVAC systems are having to do less work and live longer. As a bonus, greenhouse gas emissions and air pollution is lowered.
Cool roofs are simply reflective coatings applied to a range of roofing materials, offering great versatility to homeowners.
Sleek, Low-Pitched, Metal
A striking new trend is lower roof pitches and simpler roof lines. The shift towards low roof pitches between 30 and 10 degrees is driven by a happy marriage between height-restrictive building codes and a desire for more spacious, light and large rooms. Lowering the roof pitch not only makes the floor-to-ceiling height taller. It may also allow the creation of an extra floor to increase property value.
It helps that the minimalism trend is in key with the low-key aesthetic of this roof pitch style. Lowering the pitch also reduces the area of tiling, and consequently, the weight of the roof.
Since the lower pitch raises drainage concerns, waterproofing is important. Designers are tending towards a higher degree of lap between tiles. As a result, the more affordable (and lightweight) metal tiles are a strong design trend to watch for.
While minimalism is trendy, so is mixing materials and roof designs. Shingle and metal roofs on different roof sections give homeowners a way to enjoy the aesthetics of a metal roof and keep costs low. Designers are experimenting with different colors, roofing materials and slopes.
And underlying modern roofing systems is a system of trusses for framing and support. Designers are fast moving away from traditional rafter and joist systems for framing that is faster to install, cheaper, and flexible.
