Gutter Cleaning and Care
Clean gutters are important to keeping your foundation safe, so learn to clean and repair them with help from home improvement expert JoAnne Liebeler.
Step 3: Holes larger than an inch, but narrower than the width of the gutter trough can be patched with a small piece of sheet metal. If you're lucky, you have a piece of sheet metal lying around! If not, you may have to buy a large piece from a home center and then cut it to size with tin snips.
Spread the roofing cement around the hole and embed the patch over it. Slather more roofing cement over the seams, so it will be watertight.
