Verandah covering roof gutters. How do I clean?

[BA-XT]

Hello,

Question for the handymen - women and tradies out there, but I've ran into a snag. Bought our first house and have noticed roof is leaking in multiple areas. There's no holes from rust , just some splits that can be filled up with sealant.

My problem is that the veranda roofing ends directly over the gutters of the house and I don't have enough access to get my hand in to clear the roof clutter.

So the house gutters in about 40% of the house are concealed by the veranda plastic roofing. Is there any way around this? Or do tradies use a special tool to flush the leaves and gunk out?

Adding to my frustration is there are leaks from the veranda roof leaking into the deck. I should have taken pics today when it was raining.

Theres no rot in the wood at all thankfully. But every time it rains I end up with a wet deck! Might have to get it fixed down the track.

I can post pics tomorrow if it helps, but any opinions would be greatly appreciated.
