Metal roof dormer…no flashing?

I’m not an inspector yet, still training. But this homeowner hired me as a handyman and told me there was a leak in the covered porch underneath. I don’t see any flashing at all. Shouldn’t there be some flashing showing at least in the front? What would your report say if you saw this?

This home was inspected by an engineering firm that offers home inspections and nothing was said about this as well as some other issues.

WTF is that! I have never seen anything like it. Yes it needs flashing but how is beyond me.

How? two ways: the metal work will have a welded/sealed lip/flange and the second is you go under the metal work, it acts as counter flashing.

As for what you should see… it depends, sometimes the front/head flashing is covered with glued/cemented down row of shingles for aesthetics. There should be head flashing either visible or under first row of shingles.


Reminds me of some old industrial ductwork that was salvaged and cut to dimension!

Barrel Dormer with lots of monkey donk at the roofline. Should have welded-shaped metal flashing under the metal and shingles.
If it is leaking have a roofer check it out.


It is probably the monkey dong backing the water up beyond the flashing allowing the water to enter the house.


I’m sure with haphazard flashing we don’t see. More reason to recommend a roofer to repair.

@Marcel Cyr, So as a handy man, did you repair the dormer or hire a roofer? As a roofer, I can tell you that it’s a water damming issue. As someone pointed out, the apron flashing is covered by a shingle (cosmetically) but it is causing the problem along with not having a water channel cut back. (Shingles cut away and leaving a channel around the dormer) plus leaving an escape for the water to run off over the apron flashing. Should be a simple repair? The apron flashing will have to be exposed though.

I agree, a would like to see about 1 inch gap between the side of that barrel and the shingles. Instead, they fill it with goo.

I did not make any repairs. In my attempt to talk to a professional, I tried for 2 days to contact the roofer who originally installed the metal roofing many years ago. It was re-shingled about 7 years ago according to the previous owner. The original roofer has not contacted me. I also tried to talk to another roofer in town, but he acted like he never roofs metal to shingles, only metal or rubber roofing. So, I brought the pictures here!

You obviously have no clue who you are talking to


I would keep it that way. Refer it out.

Well, my wife says I am a good one too, well, sometimes.


Simon, wouldn’t some portion of the flashing be visible?

What portion would be visible if covered with shingles and caulked on the sides for extra measure?

There are a few places this window could leak, where the metal roof wraps down over the window casing, it was caulked part of the way up from the sill, water could get behind the metal and run in behind the flashing with no way out, but into the house, poor and Incomplete caulking and monkey dong could be your worst enemy. :grinning:

This is probably what it looks like behind the metal cladding on the sill.

This appears to be a manufactured/Prefabricated steel eyebrow dormer. The installer would follow the manufacturer’s installation instructions.

Personally, I would prefer to see, at the very least, a counter flashing apron at the bottom of the window frame. As for step and counter flashing, the radius angle would make it difficult.

Asphalt Shingles: In both headwall and sidewall conditions, unless the exterior wall is brick/masonry, you should see a gap of at least 1½ inches between the bottom of the exterior wall-covering material, sheet steel in this case, and the top of the roof-covering material.
Asphalt Shingles: Siding: 2" gap from adjacent horizontal structures.

Just my 2 cents.

It’s not an eyebrow, it’s a barrel dormer. And that was done in the field.
Notice the crimps in order to bend the vertical legs.
Done with a tool similar to this;


The dormer sits at the edge of the exterior envelope wall with an extended roof that extends outward covering a porch. You were told that it was leaking onto the porch. Is also leaking into the house?

I stand corrected.
