Roofs naturally expand and contract as temperatures change, so light creaking can be normal during cold nights and warmer afternoons. However, loud popping, repeated groaning, or shifting noises may indicate loose decking, stressed fasteners, or areas where materials are moving more than they should.

Dripping or trickling sounds inside the attic after a storm or freeze are another concern. This usually means moisture is moving through insulation or across the roof deck. Even if you don’t see water inside the home yet, this is often the early stage of a leak.

Scratching or scurrying noises often point to rodents or small animals seeking warmth in attic spaces. These pests typically enter through small gaps near roof vents, soffits, or flashing, which also allow air and moisture intrusion.
