Identify the Mystery Gutter type! [pic]
Recently bought a house with a roof/gutter system that Im not familiar with.

Basically the "gutter" is a the roofing material that creates a bowl lip at the edges and then drains down through a hole in the roofing material and substrate.

I need to replace the roof and trying to do a little research on the style of roof/gutters but nothing i've found details how to this style is constructed and how it can be repaired.

First step is just trying to find the right terminology and any online references to it.

looks like a jury-rigged system that someone was too cheap to have a proper gutter system installed. It also looks like the is some sort of vertical wooden post sticking up through the roof. Good place for rot to start. I suggest ripping it out and have a real gutter installed

I agree, looks like a jury rigged system to me too.

All too easy for debris to back the water flow up and cause water to get up under the shingles. In fact, looking at the siding coming out of the corners you may already have some water damage there.

Why not have your roofer take a look and advise you. I'm betting that he'll recommend a conventional type gutter. When the existing roof is torn off for the new shingles, take a good look for any damage.

Hi all,

Yep i wondering if this was even a "style" or something improvised but it seemed too complicated and finished to be made up. The previous owner was a pretty fastidious man in his prime but let things fall into disrepair in his later years so i was thinking it was a old style way of making a gutter system.

That vertical bar in the photo is actually a drain coming down from the main house which obviously makes the garage drainage that much more critical.

Here's another shot of the length of the garage.

It looks like it's a troth made from rolled roofing - designed to carry water to one point off the edge. The trouble is that roofing material is not really waterproof - it's designed to transfer water downwards until it runs off the edge of the roof. Since your roof has a fairly shallow pitch, the vertical depth of water needed to overflow the top end of each shingle is only a fraction of an inch. Even with the rolled roofing running up under three or four rows of shingles, between nail protrusions and any seams in the rolled roofing at the corners, even a few leaves struck on the roof will lead to a leak.

I think it's a safe bet that when you strip off the old roofing to reshingle, that you'll find a fair amount of roof decking damage.

If that was mine I'd get rid of all of it.
Add fascia boards and enclose the soffits with vinyl soffits, extend the sheathing out to the edge of the fascia add drip edge and wrap all the exposed wood with coil stock and add real gutters.
