Tisdale said: "I was delighted with the win and the performance, especially the first 45 minutes which were were exceptional.
"We did everything right in the first half. We were tough, we worked hard and we played some really good football and produced three sharp finishes to cap things off.
"It was probably the first day of winter really, with the wet surface, but we coped with the conditions really well. We passed the ball around well and created a lot of chances and produced a lot of quality.
"We showed some resilience as well because we had a few knocks at half-time. The dressing room was like a war zone.
"After the third goal Morecambe upped their intensity and that was a reminder to us that they would not lie down. We had to make sure we did not take things easy in the second half and we were very professional to see the game out."
Morecambe boss Jim Bentley said his side were undone by a "shocking" first-half display which saw them 3-0 down at the break.
Exeter took the lead on four minutes when David Wheeler slotted home Lee Holmes' perfect through-ball and it was 2-0 on 16 minutes when Joel Grant fired past Barry Roche from just inside the area.
Holmes added a third just after the half-hour with a cool finish to give the Grecians a clear advantage.
Morecambe went close on several occasions in the second half with Lee Molyneux and Alex Whitmore both going close and Ryan Edwards seeing a shot cleared off the line by Pierce Sweeney, but Exeter hung on for another away-day success.
Bentley said: "We had a game plan and almost immediately that plan was thrown out of the window as they scored a goal after just four minutes.
"It was a goal that gave them a clear lift and left us a bit shocked. Their away form has been good and you could see the confidence in their play while we looked nervous and shaky, made poor decisions and made it far too easy for them to score.
"We were much better in the second half but missed some good chances to get the first goal which may have made them a bit nervous."
