Why Does My Roof Make Noises

Banging sounds generally occur when a part of the roof has not been properly fixed in place.

Why does my roof make noises.

The sun hits your roof and heats it up. As your house quiets down at night and the temperatures fall the cooling of your roof components can often be heard. Or when it has come loose. As for the popping noise in the morning and evening that s.

When the wood cools down after sunset the same thing happens in reverse. Understanding the origin of a roof s banging requires an understanding of thermal expansion and contraction. The effects are most notable in the winter. Simply put building materials respond to changes in their environment.

The wood frame under your roof experiences temperature changes from the outdoor air because the attic does not receive much heating or air conditioning. The sound can be present both in mild weather and heavy winds. In new homes roof trusses or the wood used to frame the attic often is green meaning it still has a high moisture content. It s the sound of the ductwork in your house expanding and contracting with the change in temperature.

This flexing is what s causing the popping noise. Other noises sometimes attributed to building roofs are actually traced to other building components on or near the roof such as antennas wires cables signs and roof mounted equipment. The noise could be coming from your roof during the hottest days of the summer when the rays. At night the outdoor temperature lowers and the wood contracts.

Popping cracking and snapping sounds coming from their roofs especially when the colder weather hits is a common problem. The entire roof system if not solidly braced can and will flex to absorb this force. During the day the wood expands. As it dries it can shift and contract triggering bangs loud enough to make you think a tree fell on the roof.

This movement creates the popping noise. As the lumber expands it moves and it will rub against other pieces of wood that aren t moving at the same rate. Most likely the cause of the noise is expansion and contraction of the material used. Those noises should decrease during the home s first year or so.

Creaking wheezing or popping sounds happen at nighttime due to cooler weather. But because the knocking seems to have begun with the new roof it stands to reason that s where the cause lies. The most common noise issues with flat roofs are banging loud rain snapping popping sounds heat related cracking and creaking.
