Moving and tapping noise on the house roof

I along with the family moved from an apartment to a house in Nov 2023. From April onwards (after winter) we started hearing some noise coming from the roof of the house. Mostly it is in night but have heard it during the day as well. The noise is sometimes “tapping” and sometimes as if a small creature/object has moved from one point to another point. Curious to know what could it be. The roof of the house is sloping and built in 1990’s.

Thanks.
