I am not sure why that is relevant. No stores anywhere have Solar tiles until they do. The question is not what stores are selling, its what is the target market for the products. If you have roof that is newish,, then solar panels are superior as you are not going to tear off a good roof to put on tiles. Also, tiles do not fit every region of the country which could be why 800 stores and not all stores. You are not going to put a $50k roof on an $80k house for example. But if your home is $500k+ like many and places like So. Cal that has a lot of Spanish tile, you cannot put anything but Spanish tile on your roof in certain places. These stores would be an ideal place to sell Solar tiles. I think the biggest place where roof tiles will be used is new construction in places where higher end asphalt would have been used but certain where tiles would have been used. I dont know exactly the price point where it makes sense, but in some cases having a solar roof option on new construction would be a no brainer. People can choose from asphalt (with or without solar), tile or solar tile.
Tossing out a house at $80K is unrealistic, sadly. My wife and I bought our first house back in 1975 at $30K and sold it for $60K two years later when I re-entered the US Army. That same house is roughly $500K today in Orange County, California ~ that is my wild A$$ guess since I have not looked it up in a very long time. You know glutton for punishment
Here in Washington our son-in-law encouraged us to buy a rental ($160K) with him/our daughter back around 2010 and it has creeped up to a point ($225K) we might refinance it so that we can put a new roof on it; and make a better profit on rent. That house was a good deal since it is currently owner financed (we put minimal down) and a long time friend of our son-in-law. Our son-in-law has his own business managing rentals and has several rentals of his own. So, yes we probably will
not re-roof with Tesla tiles, but I will push, if not fund better asphalt tiles. If solar tiles are in the cards, fantastic.
At the same time, my wife and I helped them buy their current home because they were unable to purchase the house since he owned so many properties during the "Great Recession/Depression." They get it all when both my wife and I die anyway; plus the Grandpups enjoy growing up on an acre and a half of forested land in the northwest. This house I want re-tiled with Tesla solar tiles or panels within the next couple of years and will again provide the financial backing if desired. Our son-in-law tends to balk at our stepping in to assist. I know how he feels, since I had the same feeling when my parents paid for meals when they stopped by to visit us in Germany.
Then there is our lake house. The previous owner was less than an honorable human. We spent the last year and a half putting sheathing (I was including sheathing on my house drawings in high school back in '63 thru '68) on and replacing all the cedar siding with Hardie board. Now we no longer hear the wild noises outside, the house is structurally sound, and we added three pane windows for better insulation. Oh yes, the new roof within ten years. The previous owner installed medium grade roof tiles alright, but he failed to state that they had not removed the previous tiles. A practice that is discouraged currently. Bottom line we are going to replace that roof within the next two years and hope that the plywood sheets are still usable; or replace them as is necessary. Since we have solar panels on our primary house since 2013, we are comparing the pros and cons of tile vs panels. We are waiting for a input from Tesla now on our situation. As much as I am for Tesla tiles, the panels may win out. Net metering here in Washington has become a pain in my butt too. Oh, and I will not get into the story about the former owner attaching a twenty by twenty foot deck on second story with only eighteen nails holding the ledger ~ remember no sheathing either:-(
Now, living in Olympia I have to drive all the way to Seattle for service on our MX; a oneplus hour drive each way ~ god help us if there is a traffic problem. If they put a desk in Home Depot where I can talk to a human face to face that will make my day. Oh, and the desk is fifteen minutes away
While I just dodged a bullet when my wife bought a new iPhone 8 instead of the ten; talking to someone in person makes life easier.
Bottom line, I hope this aides you in understanding the previous writers question about Home Depot's carrying asphalt tiles
based on my real life scenario
Also, many of us are making this decision based on it is the sustainable thing to do. My philosophy of life is you carry back out what you hike in with ~ just sayin' Also, my call sign is MajorBS49. My philosophy of life stemming from my retired military rank and my own initials ~ again, just sayin'
Edit: If you can buy a house for $80K with good bones and rent it for over $1K; you might want to consider buying it for an investment.
