THE BUILDING ENVELOPE
Follow the water from the roof to the ground.
The roof, gutters, downspouts, grading, foundation, and interior moisture clues are one connected system. Regular observation can reveal a change before it becomes a larger water problem.
Start at the roof edge
From a safe location, look for displaced or damaged materials, debris, sagging or overflowing gutters, loose downspouts, and water discharging where it can return toward the foundation. Do not climb onto a roof or use a ladder when conditions, height, access, or your experience make that unsafe.
Then check the ground
After rain or snowmelt, note pooling near the house, eroded soil, settled areas, overflowing drainage, or downspouts ending where water moves back toward the structure. EPA moisture guidance emphasizes that site drainage should direct water away from the building.
Finish inside
Look at ceilings, exterior walls, attic areas you can safely access, basements, and crawlspaces for new staining, damp materials, peeling finishes, musty odor, condensation, or changes in cracks. Record the date, weather, and location. Active water entry, structural movement, electrical exposure, mold concerns, or unsafe access requires qualified help.
