How to repair broken gutters with adhesive

The rain gutter is a crucial component of the roof. It carefully collects the rainwater and channels it down the drainage system. However, you don’t realise if there is a problem until it starts to leak water. 

There are many ways to treat and repair the gutter but using sealants is an excellent option, and you can do it yourself. There are many options available in the market, so you can pick one as long as it says water-resistant and flexible. 

Where to check for broken gutters to repair?

Apart from the seams and corner joints, water can also leak through any area on the rain gutter. Due to the harsh weather conditions and frequent exposure to heat and moisture, even the best gutters made with the most rigid materials can rust over time. Identifying the hole or crack by cleaning the rain gutter is the first step for any repair. So if the leakage is not from the seam, search other areas for leakage on the drain. Once you do that, you can follow the same procedure; remove debris, dry clean and then apply the sealant. 

Another area where water can leak from the gutter is the gutter end caps. Generally, these caps are durable and do not break easily. But in due time, it needs replacement and repairs. After years of endurance, the caulk or sealant slowly starts to crack and cause leakages. So the first thing you should do is remove the old adhesive or caulk. You can use a knife to chop it off and make sure that you scrap it all so that the new sealant can stick well. Once you let the surface dry, gently apply the adhesive on both surfaces of the cap and let the adhesive set in for about 10 minutes. After that, you can leave it for 24 hours to dry.


It is always wise to keep sealants at home if you have a roof with rain gutters. You never know when the gutter starts to leak, and if the rainy season is near, it’s best to stay prepared. If you are from the UK, you can go for Everflex, Unibond or Gorilla Glue. They are some of the best sealants you can find in the market
