Rain gutters are one of your home’s defenses against structural damage both to the facade, as well as to the foundation. If your rain gutters begin to fail then the integrity of your home’s structure can become compromised. It is possible to replace or repair your rain gutters by yourself if you have the right equipment and the proper do-it-yourself know-how.
Find damage first by doing both a visual and practical test on the rain gutters. Inspect the gutters to see if there are conspicuous points of weakness either as a result of puncture damage or from the weight of debris buildup. Pour water into the gutter as well. If the water doesn't proceed directly to the drainpipe then it is not properly slanted any longer.
Plug major holes in your roof using roofing cement and sheet metal. Simply place the metal directly over the damage and use the roofing cement to secure it in place. Be sure to provide ample coverage for the metal seal while keeping the cement smooth to permit continued water flow.
Use silicone caulk to plug up smaller holes in the gutters. Stress fractures are ideal candidates for silicone caulk repairs.
Replace older rain gutters with newer ones in the event that they prove beyond repair. PVC gutters have gained popularity because of their durability, as have seamless gutters.
Replace structural supports wherever they appear to be failing. Brackets that are failing will not support the gentle slope needed to keep water moving in the gutters. They will also end up pulling the gutters clear off the walls if they get too weak.
