Roof Leak Water Damage in Columbia, TN

How storm damage lets water in

During the May 8 to 9, 2024 storm event, the National Weather Service recorded hail up to apple size and at least 4 tornadoes across Middle Tennessee. Hail bruises shingles, wind lifts flashing and peels sections away, and one small opening is enough to send water into the attic with every rain that follows. That is why a roof can look intact from the street and still let water in. The NWS damage survey followed the tornado across Iron Bridge Road, Mount Olivet Road, Cothran Road and Cranford Hollow Road before it crossed Highway 412.

Following the water down

Roof water takes a predictable path.

• Through the decking and into attic insulation, which holds it like a sponge
• Along rafters and the top plates of walls
• Out through a ceiling as a stain, a bulge or a drip
• Down into light fixtures, walls and flooring below

Because the path is hidden, moisture readings matter more than what the surface looks like. A wet attic also raises humidity, so the underside of the roof deck is checked for dampness as well.

Attic first, then the rooms below

The attic is inspected with a moisture meter and a thermal camera before any ceiling is cut. Wet insulation is removed, damp decking is dried and ceilings are opened only where they hold water. Insulation that has soaked through is heavy and slow to dry, so it comes out rather than being fanned. Rooms below are checked wall by wall, because water can run down inside a wall without marking the ceiling.

Roofer and drying team roles

A roofer tarps and repairs the opening, because restoration crews do not do roofing. Emergency tarping stops more water from entering, and the drying team documents how it got in. Keeping the tarp invoice and the roofer's findings beside the drying logs gives the adjuster one complete file. Interior work is covered in ceiling leak water damage and structural drying.
