Chimney & Skylight Leak Sealing

Chimneys and skylights are two of the most common places for a roof to let water in, since both interrupt the roof deck and rely on flashing, sealant, and careful metal work to stay watertight. Movement, sun exposure, and age can open small gaps around a chimney's flashing or a skylight's frame long before a leak shows up inside the house. SmithBuilt Roofing and Exteriors traces these leaks to their source and seals the assembly properly rather than just patching the spot where water appears on a ceiling.

Finding the Actual Entry Point

Handheld Infrared Cameras — thermal scanning inside and out that traces a leak back to where water actually enters the assembly, rather than where it happens to show up.
Moisture Meters — direct readings through decking and insulation around the chimney or skylight curb, showing how far water has traveled under the surface.
Drones with Thermal & High-Res Cameras — aerial imaging that checks flashing and cap conditions without anyone standing on a fragile or steep section of roof.

Sealing It Properly

Tin Snips & Hand Seamers — hand-fit metal work at chimney flashing where a machine cannot reach.
Caulking Guns & Heat Guns — sealant and flashing detail work done at the right temperature so it bonds instead of peeling in a season.
Wood Moisture Meters — a check of nearby decking so anything wet gets addressed while the area is open.

Progress on each job is documented with time-stamped photos, so you can see exactly what was found and what was sealed.
