Repairing Leaks in Gutter Railings

6. Clean the leaking area with a wire brush and water.

7. Dry the area and rub with coarse sandpaper.

8. Cover the hole with plastic roofing cement. Spread the cement at least 2 to 3 inches around the hole.

9. Cover with a piece of flashing (sheet metal) if you're dealing with a large hole; press the flashing into the cement and feather the edges of the cement to hold the flashing in place.

2. Use a metal brush to scrape off the grime and muck in a 2" radius. Or, attach a metal brush to your drill and do it that way.

3. Clean off the area with a cloth.

4. Apply Shenna (Tremco 380 if you cleaned it really well) on the corner, going from the bottom corner to the top. Allow about 1-1.5" of silicon down the center. Wipe the edge in an outward motion, leaving the center alone. Make sure you get the very top and back corner.
