My root gutter is leaking water through the gap between 2 gutters. What material can I use to seal the leakgage?

I’m considering something like silicon or tile grout filler.

Thanks in advance! 🙏

Use those sticky tape for water leak. I dun think silicon can be use to seal it

Can share example of sticky tape? Duck tape?

On a hot non-rainy day, apply roof sealant. Those black stuff.

Clean debris b4 using clear/transparent silicon. Use flat ice cream stick to push the silicon into the gap for first coat including screw holes. Then apply 2nd coat. Seal 2 sides, in and out.

need to climb up and see from the top to see the whole situation.

sealing from below wont work

waterproof tape.
from Mr. DIY.
under rm15.
after cleaning the area of rust n debris, apply one layer top n bottom to cover holes.
not a permanent solution, but it's quick n cheap.

or cut a piece of metal sheet (eg. milo tin) and cover area with epoxy steel, then tape over it top n bottom.
good luck.

Go diy shop buy those Bitumen tape.

Clear silicon gives a neater and clean sight after repair. Injection of silicon goes deep into the fine crack.

Nevertheless, tapes can also be use.

U can use bitumen just paint over the whole area (from inside the gutter).
