Elon Musk, the head honcho of Tesla Inc. that pioneered the large-scale use of plug-in electric cars and also specializing in energy storage solutions and solar panels, declared at a conclave that solar energy could power the entire US. At the National Governors Association Summer Conference held in July, he elaborated on how all the homes throughout US can be powered up solely with solar roof tiles. He elucidated that it would require a reasonably small area in Utah, Texas or California for installing 100 sq. miles of solar panels in order to accomplish the task.
Last year in October, Tesla released its up-to-the-minute products-an advanced Powerpack 2 and Powerwall 2, energy storage solutions and a versatile solar roof. In that year, Musk bought out SolarCity, a frontline photovoltaic cell manufacturing firm shelling out US$2.6 billion, synergizing its operations with those of Tesla. The merger enabled the innovative entrepreneur to promote the entire product line of Tesla, including solar roofs capable of fully replacing fossil fuels for meeting a home’s overall energy needs.
The energy that Tesla’s solar roofing taps from the rays of the sun is preserved in the Powerwall 2 which is technically speaking a battery for use in residences with a 14kWh rating. At daytime, the rows of solar shingles or tiles produce electricity as well as charge up the battery packs which thereafter lights up homes at night and also runs sundry appliances. Subsequently, the homeowner is relieved from the necessity of subscribing to a conventional utility service for fulfilling his electricity requirements.
Does it imply that solar roofs of Tesla will give utility and energy companies, a run for their money and eventually compel them to go out of business? As of now, that is still just a remote possibility and hence the idea may seem a little farfetched presently. Coming back to basics, each and every unit of Powerwall is sufficiently capable of supplying electrical power for a whole day.
To be precise, a typical Powerwall battery can be restructured and adapted to deliver the combined power of 9 such packs from a single unit. Alternatively, Powerpack2 which has been exclusively designed for heavy-duty commercial use is scalable to an unlimited extent. The solar roof is made up of photovoltaic cell units that are layered with glass tiles and colored optical louver films.
Tesla right now is offering four different types of solar tiles that have been designed with painstaking care which makes them appear like traditional terracotta, slate, wooden, asbestos, and metallic roofing shingles. Elon has taken advantage of a hydrographic printing technique for making his solar panels look nearly identical to conventional rooftop materials. Musk’s company started taking orders shortly after the conclave in which he outlined the benefits of the solar tiles.
And Tesla began processing the orders and rolling out the roofs from August. Melon is confident that the homeowner will be able to recoup his or her solar roof investment over a 30-year period and accordingly offering a warranty for a similar time period.

When it comes to understanding your current (or future) roofing system, there is no “wrong” question. As a homeowner, it is essential that you ensure the integrity of your roof at all times, properly care for and maintain the shingles, and protect it from outside elements that could lead to damage that could have otherwise been avoided.
Let’s review the Top 5 Frequently Asked Questions about residential roofing – which in some cases also apply to business or industrial roofing setups.
1. How do I know when it’s time to purchase a new roof?
Typically, roofing shingles or wooden shakes will last between 15 to 30 years, depending on the weather and environment you live in, as well as any obstructions or damage from surrounding elements – such as branches. Another common trouble with worn or broken tiles is inadequate water irrigation systems, and flooding on your roof which may eat away at your current roofing system at a higher rate than anticipated.
Some signs of a broken or beyond repair roofing system needing a total replacement are: curling shingles, decayed or missing shingles, visible cracks, missing or rusted flashings, wind damage, missing shingles, and cracked or discolored interior drywall.
In such instances, investing in a professional roof replacement by a trusted roofer would likely make the most sense.
2. How much will a new roof cost?
Depending on the type of roofing system you choose, as well as the roofing professional you hire, prices can vary significantly. Also, take into consideration the grade, brand, and type of roofing systems you’re going to go with, as well as the size of your roof and if it has a sloping roofline.
Starting with an expert roofing professional is the way to go, and often you can receive a free quote in doing so. Don’t settle for cheaper materials or labor, as this can be more costly in the long-run for repairs, or an otherwise improperly installed roofing system.
3. If I’ve received three various offers for repairs or roof replacement, how do I know which one to go with?
Depending on the scope of work to be done, whether it’s removing entirely or fixing your current roofing system you should take into full account the necessary work. In many cases, flashing work, ventilation or adding new vents, and removal-costs might be included in the quoted price – or additional. Also, the installation method, as well as proposed deadline should play significant roles in determining which professional to go with – and why.
Other variables to take into consideration are payment procedures, and of course length or type of warranty, such as what is covered in the instance of poor installation, improper workmanship, or even water leakage later on.
4. Why has my professional roofer only offered one year warranty on my asphalt shingle roofing system?
It is important to create a distinction between a manufacturer’s warranty and a contractor’s warranty – which is typically one based solely on his or her workmanship. However, a contractor’s warranty will likely offer much less coverage and typically remains relevant only to installation issues. Therefore, carefully review the contract and warranty details to see what’s covered or isn’t before starting the work. Always ensure you also receive the necessary certificates, documents, and warranty or guarantee contracts for your new roofing system.
5. Can I replace or repair my current roof on my own?
Speaking frankly, attempting to change or repair a roof on your own can be very dangerous, or even more costly in the long run. Typically, professional roofers have years of experience, and certain qualifications, licensing and insurance that the average home owner will either not be familiar with or possess. Worse, an everyday homeowner might damage the roofing system further, accumulating even more unwanted costs.
Also, the professional equipment – including safety equipment – necessary for most roofing system jobs and installations are very costly, and may not be something considered by the average DIYer.
Ultimately, depending on the style, materials, and type of home you have, roofing experience, and installation can vary greatly. This is why it’s so important to go with a reputable, trusted, and licensed roofer.
If in doubt, continue to research online the various types of roofing systems available to you, and what might make the most sense given the climate and environment you live in.

The rooftop which shields you and your family from the elements as well as protects the interiors is that part of the home which is vulnerable to suffer the maximum damage in the long run. However, when it comes to renovating the home, most homeowners or property developers tend to focus more on revamping the inner sections, postponing upkeep of the roof. The rooftop, needless to say, is the most significant structure of your dwelling that not only shelters you from the vagaries of weather but also help maintains the market value of the residence.
So, you can afford to continue avoiding taking care of the top of your house at your own peril. But how’d you make out whether you need to opt for a routine repair job or go in for roof replacement? Of course, reroofing either partially or wholly might be rendered a futile exercise and an expensive affair if a simple patching solves the issue. However, the line that demarcates patching from replacement can get blurry sometimes and therefore it is necessary to conduct research to get to the root of the issue. There are some tell-tale indications based on which you can decide whether roof replacement would be more feasible than repairing or vice versa.
1. Has your roof become too old showing signs of decay?
The roof serves as the protective layer or shield that weathers maximum wear and tear as well as damage from inclement weather. The rooftop braves the ravages wrought by rainwater, sultriness, heat, and snow in order to keep the inside of your home comfortable throughout the year. There must have been times when a snowstorm or hurricane wrecked heavy damage to the shingles and there are signs of the rooftop creaking as it not able to keep out hot or cold air with the same effectiveness as it once used to.
In case you built or purchased your dwelling in the seventies or eighties and didn’t carry out repair jobs periodically, it is high time you started considering roof replacement.
2. Is your roof simply leaking?
Don’t get unnerved if droplets of water fall on your head or if you spot dampness on the walls of your living room. It could be that leak or leaks may have developed on the roof or under the attic beneath the rooftop. After carrying out a thorough inspection if you find that only a particular section on the top, either on the eaves or an area between the shingles (or in the loft) is leaking, only a simple patchwork that plugs the seepage will fix the problem. In such a scenario, going in for reroofing will simply not be required.
3. Keep an eye on shingles
The shingles or pebbles on the roofs of homes situated in hot climes harden up and crack over time. In case you spot this issue, you can assume that the deterioration or damage is spreading underneath. Only a roofing contractor can tell you what’s going on, so hire one.
4. Repair and save
If you spot a leak, plug the seepage without delay and start saving for a roof replacement that may become unavoidable in the future.
