What's actually causing this
Roof leaks most often occur at flashing — the metal strips that seal roof penetrations like chimneys, skylights, and vent pipes. Damaged or missing shingles and cracked vent pipe boots are also common causes.

Step-by-step fix
-
1
Locate the leak from the attic
On a sunny day, go into the attic and look for water stains, mold, or daylight showing through the roof deck. Trace the stain uphill from the interior drip point to find the actual entry point.
-
2
Inspect the flashing
From the roof, check all flashing around the chimney, vent pipes, and skylights. Look for gaps, lifted edges, or cracked sealant.
-
3
Reseal flashing
Clean the area with a wire brush. Apply roofing caulk or self-adhesive flashing tape over any gaps. Press firmly and smooth the edges.
-
4
Replace damaged shingles
Lift the edges of surrounding shingles. Remove roofing nails from the damaged shingle with a pry bar. Slide the new shingle in place and nail at the top edge. Cover nail heads with roofing caulk.

5
Test with a hose
Have someone inside the attic while you slowly run a hose over the suspect area. Start low and work up. Identify the exact entry point before it rains again.
