Green Tech Developers - San Francisco, California

Highly recommend Ditson and his team. I contracted with them to remove my existing solar panels and re-install them after installation of a new roof. Ditson was always super responsive via text and his prices were more than fair. He was very flexible with last minute scheduling delays due to other work backing up. His team came in, did the work quickly and efficiently and returned on a weekend to finish the job after the roofing work was completed. Really appreciated Ditson and his team. Thanks!

We had an excellent experience with Ditson and his team! After the company that installed our original solar system went bankrupt, it was incredibly difficult to find anyone willing to take on the relatively small job of replacing our solar inverter. We reached out to several providers, and most didn’t even bother to respond. Ditson was the exception. Not only did they promptly schedule the job, but they also provided the most favorable quote by far.

What really set them apart was how they took the initiative to coordinate the warranty details directly with the manufacturer, which saved us a lot of time and hassle. The whole process was smooth, and they were quick to address any concerns we had.

All in all, they were responsive, professional, and quick to resolve an issue we thought would take ages to fix. We highly recommend Ditson and his team for anyone in need of solar system support!

Green-Tech Developers are very professional on what they do. I was surprised and efficiently and professionalism on doing many trades and solutions. I did my roof, Solar, HVAC, Electrica upgrade and my bathroom in 2 weeks. Impressed on quality and time management. Most people offered 3 months scope and they did it on time and targeted my complete satisfaction. Thank you GreenTech Team…

Attention everyone,

I just had to share my experience with Ditson at Greentech because, frankly, it was a complete disaster. If you're thinking of working with them, I strongly advise against it.

At first, Ditson and his team seemed like a dream come true. They were quick to impress us with their smooth-talking sales pitch and managed to secure our business in no time. However, once the actual work began, it was clear that they were way out of their depth.

Planning for install was him letting us know very late the night prior that his team is going to install the next day and that he was going on vacation, very unprofessional.

PLEASE BEWARE OF HIS CONTRACT! It's not specific on what you are going to get.

Our solar panels took forever to turn on, and it turned out that the blame fell squarely on Ditson and his team. It seems they either didn't bother to double-check or simply didn't care about the details. PGE informed us that the panels installed on our roof were incorrect, and there was a glaring discrepancy in the paperwork. How did they mess that up?

I can't help but suspect that Ditson and his crew were trying to pull a fast one on us. It wouldn't surprise me if they deliberately installed older models while charging us for brand new panels. Their lack of integrity is truly disheartening.

The level of incompetence displayed by Ditson and his team is simply unacceptable. Not only did they fail to deliver on their promises, but they also caused unnecessary delays and wasted our time. I wouldn't trust them to install a lightbulb, let alone handle something as significant as solar panels.

To anyone considering working with Ditson at Greentech, I implore you to look elsewhere. Don't be fooled by their smooth talk and quick booking tactics. They are clearly terrible at the actual work and paperwork involved. Save yourself the headache and find a more reliable and trustworthy company to handle your solar needs.

We just replaced our 20+ year old roof with GreenTech Roofing. Denis and his crew were a pleasure to deal with. We have had leaks which have destroyed our family room ceiling twice. Each time another roofer attempted to fix it but didn't get to the root of the problem. Denis water tested the roof when he was finished, and guarantees his work for ten years. Our leak worries are over.

They also re-insulated our house while they had access, installed an attic fan, and will return to pop in a new shower skylight. They used Plastic Sheeting to protect decks, outdoor furniture, and plants, and were diligent about picking up the little bits of roofing paper that blew further afield into the garden.

Denis has a references list and he did share with me. When I spoke with a couple of references they spoke highly of the GreenTech. I'm very happy with their work. If you looking for a good roofing company you definitely have to contact them. You can't go wrong with GreenTech Roofing.

Having your roof replaced is not something any of us likely rush into. We hired GreenTech because of a recommendation of a friend. The guys were super thorough, fast, and very flexible with timing. We were trying to schedule a roof replacement between rain storms. Great job, Hard workers, Daily clean up. I would recommend using them in any construction projects. They're have all the licenses and insurance, their quality of work and customer service is outstanding.

GreenTech did work for church in Daly City- almost 19k usd. After three years a 40-50 mile wind lifted a section. When we called to see about the warranty, they could not find the contract and when I sent it to them, no response. I finally told them, just forget the warranty just repair the roof and we will just pay for it but no response. When Vlad ( employee if Greentech) made a presentation to the church as to why we should hire their cimpany he made all kind if promises but now we urgently need them- no response. Save yourself some frustration, use other companies than this one.
