Hi,
Dropped in from Knots with a roof question.
I live in a notionally dry part of Australia, but have a few roof leaks (these haven’t been a problem for a year because of drought). The house was built in ’72 and extended in 83. it has a tile roof with a pitch of about 20deg and 4 valley gutters, three of which seem to be a problem.
The master Bedroom is under one of the valleys and has regular leaks. I have a lot of trees, including a sivler birch next to the roof, so frequent cleaning keeps the problem down a bit. Last week we had a heavy storm, about 70mm of hail on the ground, 33mm in the rain guage in about an hour. there were several very heavy leaks, incluing through the light fittings.
I seems that most of the water is coming through the valley gutters. My assumption is that they were dammed by the hail and then over flowed. Now, some of you lot live where it snows so I figure might have some suggections as to what to do with the roof. I would prefer to keep a tile roof, but suspect that the gutters need redesign.
Thanks
Dave

Hello!
There may be some differences between heere and there.
We call them Valley flashings in the states. Gutters to us would probably be eaves troughs to you.
We lay tile with a couple plies of 30# tarpaper under them. The actual water resistant roof is the tarpaper and the tiles are there to shed 98% of the water.
Your roof is a fairly low pitch but generally acceptable for a dry climate.
Problem now is that it isn't always dry, and you have some age on it.
It is not uncommon to redo a tile roof by carefully taking them up, replacing tarpaper - sometimes with modern ice and water shield bituthene - and new valley flashings, then resetting the tiles. Occasionally this is done in just the valleys.
There is a fellow here at BT named John Sprung out in S california who has done his house this way I think and who has some photos. Hopefully he will come along.
some other names to be on the lookout for are Seeyou(CU is the symbol for copper and Grant works with it well and does roofing too) and slateman whose skills with slate and flashings are similar to that used in tile work
Are your tiles the kind that lay in place with a nib and gravity to hold over slats or are they nailed in place directly on the tarpaper? Do you know?> Do you have a digital camera that you could use to introduce us to the details and overall look of your roof?
Gotta get to work soon now - later....

Thanks for your response.
No chance for pics untill the weekend, but the tarpaper - its foil covered on both sides under this roof is in pretty shocking condition. There are also places where the wind has blown leaves between the tiles and the foil near these gutters.
So it looks like if I lift the tiles to do something about the valleys I should lift more to replace the paper? My only real problem with that is the skill set to repoint the end (gables?) and the ridge caps with mortar.
Ill get back after I take some shots,
David
Are these clay tiles or concrete tiles set in mortar?I'm sure my confusion has something to do with regional differences in practices.Are you trying to DIY this job or to know what to do to get a contractor on it?
