Hanging Roof shingles..

carmel64

Can anyone tell me if this is normal to have the roof shingles hang off this way after installling hardie lap siding? It seems to me that they should sit flush to the very end of the siding. Will this likely cause any damage to the shingles?

I can't get your pic to open up larger....

Just how far do the shingles stick out? 1/8-1/4" is about right....an inch or more would be an issue...

Sorry, cannot see a thing in the way the picture is formatted (really small).

Roof shingles, in areas not prone to hurricanes, standardly overhang the aluminum drip edges, which in turn overhang the fascia trim boards. This allows rain water to drop free and clear of (not run-down) the wood trim, or other siding material that are installed on the structure.

One issue will find happening soon will be the ends of the panels where it's in direct contact with the shingles will start to bubble up and the finish will fail.
It was suppost to be at least 2" away from the shingles, and the end cuts needed to be sealed with paint.
I use vinyl 1 X 4 lumber, a strip of Z moulding, a strip of vinyl lattis to kick out the siding, then the siding to prevent premature failure.
May want to Google the install manual on Hardee lap, it's even shows a picture of what I'm talking about.

So my concern should be more on the siding than on the shingles? I just wasn't sure if the shingles that hang over will be compromised in any way? Thank you for your kind response!

There is information in the Hardie Installation Link that addresses and diagrams - that a gap should be left between the siding and the roof shingle surfaces on Dormer sidwalls configurations (during the siding installation process).

Please refer to page 2 in the link: http://www.jameshardie.com/pdf/insta...eplank-hz5.pdf

Don't know if this helps you......

We still have no idea what you mean by the shingles are hanging over. Hanging over what?
They should hang over the edges of the roofs edges.

Okay, I think you just answered my question...it's okay to then to have shingles hang over the roof edge. Thanks!
