Hi @arun11australia,

The first step would be to identify where exactly the leak is getting into the eaves and why it is happening. Have you had a chance to inspect the roof and gutters? How do they act during a heavy downpour?

Are there any small gaps in the gutters? Are the gutters clear of leaves and debris? Are your gutters getting overloaded in heavy downpours? Are the gutters sloping towards the downpipes as they should? 

Small gaps can be sealed with things like silicone or waterproofing tape. If, upon inspection, you find that a small gap is the issue, then you may be able to seal it relatively easily with something like this.

If you find there are a lot of leaves built up in the gutters, then clearing the gutters would certainly help. Leaves can block the natural flow of the gutters, causing them to back up and overflow.

If the issues are because the gutters are being overloaded, then you would need to look into replacing your gutters. Deeper and wider gutters can hold a larger volume of water before they overflow, so having larger profile gutters installed could be an option.

If the gutters are not sloping the correct way, causing water to pool at the corner, then correcting the slope of the gutters would be worthwhile.

Simple things like sealing up gaps and cleaning out leaves and debris would be a start. If the issues are more systemic and relate to the capacity or slope of the gutters, then I'd suggest you speak with a roof plumber for their guidance. These are not issues that are particularly simple to fix and the expert advice of a professional would be worthwhile.

Allow me to tag our knowledgeable, members @Dave-1 and @Nailbag to see what they think.

Good Afternoon @arun11australia 

One of my mates had a leak in his roof that was "untraceable" and drove him nuts. After numerous checking and getting various companies out to look it turned out to be a cracked tile underneath the edge of the valley that was allowing water to enter. As a first step I would check for leaves or something else that is caught and diverting the water off the metal channel. Second step would be to look under those connection points of your awning that go through those tiles. Depending on how they have been sealed they could be allowing water in.

Hi @arun11australia 

The first step is to check the obvious entry points that @JacobZ outlined. 

Water ingress can travel some distance from the actual entry point such as a cracked tile then along a rafter to the lowest point. So next step would be to start low and off to one side with a garden hose on a light pressure and work your way up. If no result than do the same from the other side. But before starting this, I would slide back the bottom row of tiles and every 2nd on the next row in the area where the water lies in the eve. This will hopefully enable you to see where water is coming from.

These are the steps I followed when in my last house the eve flooded in one spot during long periods of rain. The tiles in the area and the flashing were all in excellent condition. It ended up being a small crack in one tile several metres away but the water travelled along a rafter. It did my head in for many weeks!

Hi @arun11australia,

Roof valleys often cause problems; we had one at the previous house and I found myself mixing up colored mortar in a kitty litter tray a few times.

Something I came across myself and when helping others was chunks of mortar that had come loose and ended up at the bottom of the valley.

Mortar doesn't stick well to metal.

Already mentioned here where the water is leaking in can be some distance from where it comes out - ridge tiles.

I usually go in the roof space with a torch and look for damp timber.

Cheers
