The performance was broadly in line with expectations after the East Kilbride-based company warned in July that earnings would fall.
The results come just over a year after shareholders failed to support in sufficient numbers a £73.1m takeover offer from Ontario Teachers' Pension Plan that had been backed by the Goals board.
"We are pleased with the performance," Mr Rogers said.
Goals has hired staff in roles in e-commerce and marketing. It is also developing features such as applications for mobile phones designed to make it easier for team captains to arrange payments and player replacements.
"It is investing for the future of the business," Mr Rogers said, allowing it to cater to future site openings.
Goal's shares closed up 1.5p or 1% at 153.5p.
Goals, which has 43 centres in the UK and another in Los Angeles, has frozen new site openings as it focuses on paying down debt and improving its operations.
For the six months to the end of June, it posted a 2% rise in sales to £16.6m and saw a 1% rise in like-for-like sales.
But core football revenues remained flat on a like-for-like basis, a performance the company said was depressed by snowfalls early in the year,
Goals saw net cash generation rise 27% year on year to £4.8m.
This allowed it to cut net bank debt 11% to £48.1m compared to bank loan facilities of £51.25m.
Mr Rogers said its banker Bank of Scotland has been supportive and said he was confident that cash flow and profits would allow the company to recommence its building programme next year.
The scale of expansion will be decided "in the next few months".
"We have lots of sites in our pipeline," he added.
The company confirmed that its expansion plans could include the United States where it opened a site in 2010.
The company has developed a modular building that it believes will slash future opening costs.
Mr Rogers insisted that Goals could thrive as a public company despite the plunge in its share price after last year's abortive takeover bid.
"The business is very successful," he said.
Wayne Brown, analyst at house broker Canaccord Genuity, wrote in a note to clients: "The management team has been bolstered at the operational level, the board has been strengthened with the appointment of Keith Edelman as chairman and we are already starting to see a recovery in trading."
Mr Brown, who has a target price of 200p on Goals shares, added that bid speculation as well as trading improvements could lead to a rise in its share price.
Karl Brune, analyst at Panmure Gordon which has a 120p target price on the stock, said: "We have a "Hold" recommendation on Goal Soccer Centres; however we believe the restart of the rollout and lower capex (capital expenditure) modular concept could yield upside to investors, albeit at this stage it remains unclear as to the scale of the company's growth plans, with net debt reduction said to be the key focus."
Goals said prioritising debt repayment meant it was holding its interim dividend at 0.675p to be paid on November 29.
