He's a perfectionist, you see. It's all a far cry from the Vicarage Road pitch he inherited from the Spanish contractors in January last year.
"I came in and the pitch had just been re-turfed," he said. "The job was to get that pitch through to the end of the season. The fact we managed to present it quite well was a bonus. We just had to try and provide a consistent surface week-in, week-out. It was never going to look that pretty but we got there, just about. It didn't look a patch on what we have produced this season."
Not half. Tingley was firefighting until the end of last season. "My role really began in the summer," he said. "I was basically looking after someone else's pitch until May."
As soon as the final ball of last season had been kicked, against Sunderland, the pitch was ripped up and relayed under his supervision. The club went back to the Desso surface that was installed a few years ago. The Desso surface, which is used at Tingley's former club Arsenal, was first installed at Vicarage Road in 2012 and sees the grass reinforced by millions of Desso artificial fibres.
"Relaying the pitch had to be done," said Tingley. "That was one thing I insisted on when I met with the club. They knew it had to come up. We had a reinforcement system on that pitch that was turfed over so the reinforcement system was inactive. We had to remove the turf and go back to the reinforcement system."
Without getting all Alan Titchmarsh on you, Tingley and his team went back to basics. Forty millimetres of turf was removed; the pitch was stripped back to the previous Desso surface and then reseeded. One hundred and forty tonnes of sand was brought in.
"It's about producing a surface that was going to last all season," said Tingley. "You get the reward for the work you do in the summer over Christmas and New Year. If we hadn't done what we did in the summer then the pitch wouldn't have made it through the four games over Christmas and New Year."
The manicured pitch came through with flying colours during the unforgiving festive period, the acid test of any football pitch. Perhaps the best marker of how good your pitch is is when nobody is talking about it. Much like a good referee.
"There was no guarantee I could make it better than it was but I knew through hard work and doing the right things on a regular basis, we'd have a chance," says Tingley.
"The pitch failed before as the right things weren't being done on a day-to-day basis. It can be quite scientific but it's not rocket science."
It's taken a fair amount of spade work from Tingley's nine-strong staff and a certain amount of cash to fulfil his vision.
"The club have invested massively in my department," he said. "Clubs want a good pitch but some are not willing to pay for it. Here they do."
For starters, there is the gas bill for the undersoil heating and the electric bill for the six lighting rigs, which provide artificial light to help stimulate growth, essential in the absence of regular sunshine during the grey winter months. They are what create the hazy orange glow you'll occasionally see over the ground at night, especially when it's foggy.
"Such is the demand for quality pitches in the Premier League that we use the pitch lights to ensure quality of surface, particularly as we cannot control the weather. The glow is due to the open nature of the stadium," said Tingley.
The upshot of the investment has been a happy bunch of players.
