You rely on your roof to keep your house pleasant and dry, whether it’s pouring, the sun is blistering, or it’s a winter wonderland outside. An outdated or inefficient roof can raise energy costs. And make it difficult to maintain temperature control. If you’re concerned about your roof’s efficiency or considering the advantages of a new roof.
With house insulation, you may save up to 10% on your energy bills without ever touching your roof. Insulation improves building energy efficiency in two ways. Roof deck insulation, like external materials, prevents outside temperatures. Insulation also keeps expensive, conditioned, or heated air from exiting your house.
Reducing the need to run your HVAC system as much as possible. Prices might range from a few hundred to a few thousand rupees. Depending on the scope of the job and the insulating material chosen. Insulating your roof and attic should cost far less than replacing your roof. Insulation is a cost-effective way to cut your energy expenses without having to pay for a new roof.
Any roofing solution that lowers the energy consumption of the structure below qualifies as an energy-efficient roof. Energy-efficient roofing offers a 3 in 1 solution, whether you want to cut your energy costs, qualify for tax breaks, lessen your carbon impact, or all the above.
Exterior elements, such as what goes on the outside of a structure. As well as inside components like insulation and ventilation, are all considered energy efficient.
If you live in a hot environment and your old roof is still in good shape, a cool roof coating can save you money on cooling bills by up to 30%. The roof’s capacity to reflect and emit heat is maximized with these white. The brilliant white hue on sloping roofs detracts from curb appeal in most circumstances. This is why cool roof coatings are better suited to low-sloped roofs.
What is the SRI number?
Whether a roofing material is energy-efficient is determined by who you ask and the roof slope. To be certified by Energy Star, steep-slope roofing materials must have an SRI of 25 at the time of installation and 15 three years afterward. LEED only gives credit to pitched roofing materials that have an SRI of at least 39 when installed and 32 after three years. Each of these guidelines specifies more stringent criteria for low-pitched roofs.
ASPHALT SHINGLE ROOFING
Asphalt shingles may achieve acceptable SRI ratings and even meet energy efficiency regulations. When impregnated with reflecting grains, all at an unbelievable price.
In most situations, cool roof shingles cost between Rs. 260 and 450 per square foot, making them the cheapest energy-efficient roofing material. Most shingles, yet, do not have these covered granules. Look for goods that include them or fulfill energy efficiency criteria.
METAL ROOFING
Metal roofing comes in a variety of forms (panels, tiles, shakes), substrates (steel, aluminum, copper), and colors to suit both residential and commercial structures, but one thing is certain: it saves energy. Energy savings of up to 25% can be achieved by using lighter colors and installing ventilated metal roofs.
Metal, besides its energy-saving qualities, has gained a reputation as one of the most environmentally friendly roofing materials due to industry recycling initiatives. Many manufacturers use recycled materials in their new metal roof products. Of course, at roughly Rs. 825-900 per square foot, a metal roof will be more expensive than an asphalt roof.
TILE ROOFING
Tile roofing promotes energy efficiency due to the nature of its installation. Which experts discovered may reduce annual air conditioning expenses by as much as 20% in the sweltering heat of Southern California.
As each course of roofing tiles overlaps, channels form above the roof deck. These air channels serve as a more layer of insulation. As well as a path for hot air to escape before it enters the building exterior. Concrete and clay, the principal materials used to produce roofing tiles. Because they have high thermal emittance values by nature.
Tiles are not for everyone. One of the disadvantages of tile roofing is that it costs roughly Rs750 per square foot. Which is more than twice as much as the cheapest asphalt shingle roof.
SOLAR TILE ROOFING
The only thing better than a roof that saves money on energy is one that creates it. Solar tiles, like traditional that convert sunlight into electricity. Unlike solar panels, which may be unattractive, they have the graceful profile of classic tile. Solar tiles provide you with sustainable energy savings without sacrificing aesthetics.
Solar tiles are not inexpensive when compared to non-solar roofing materials. Tesla, the most well-known solar tile manufacturer, prices between Rs. 1000 and Rs. 1500 per square foot of solar tile, without including ancillary equipment.
GREEN ROOFING
No other roofing material comes close to green roofing sustainability.
Green roofs are soil and plants growing on top of a flat roof. As a roofing material, this primitive mixture has been used for thousands of years. Green roofs are popular among today’s sustainable urban planners. Because they mitigate the urban heat island effect which causes cities to be hotter than surrounding areas.
Green roofs are energy efficient because they absorb solar radiation and offer insulation. Which makes the building more pleasant. According to one research, a building with a green roof reduces air conditioning consumption by more than 75%.
Green roofs provide a long range of personal and social benefits. This includes increased roof lifespan, stormwater retention, and natural beauty. The price of a green roof varies from Rs. 750 to Rs. 1500 per square foot. Some green roof solutions need frequent maintenance, which might increase lifetime expenses.
