850 sqft. Addition to house - Rockin' and Rollin'

[EddieWalker]

Looks good. Are you replacing the roof on the existing house too?

One of the areas where I see a lot of problems is where the roof touches a wall, and they didn't use metal flashing, or they used the wrong metal flashing. The next big mistake is not leaving a big gap between the siding and the shingles. I shoot for an inch and a half space between siding and shingles. You can paint the flashing so it's not so obvious.

This is what happens when the siding touches the shingles. It's very, very common.

Yessir, whole house and not a moment too soon. This existing roof has had it and all the walking we have been doing on it has not helped at all.

Yeah, that does not look good.

Yes, step flashing has already been discussed. The same guys that are roofing it are more than likely going to side it as well. They come highly recommended and seem to know their stuff well from the couple of times I have talked to the guy. Rooofing and siding are 2 things I knew I was going to contract out. I will be inside in the A/C and or shade finishing up framing, etc. I am done toiling in the sun this summer.

Go to Page 23 and look at picture at the top, 4.31 It shows that the gap is supposed to be 2 inches between the shingles and the Hardie, with the flashing exposed. I thought it was 1 1/2 inches, so it was good that I read this again.

I have no idea if your crew knows this or not. Here in Tyler and Longview Texas, and surrounding towns, it's almost always done wrong. The guys installing it are working as fast as they can, and reading up on the instructions from Hardie isn't on their list of things to do.

Thanks! I will make sure to keep an eye on that. Luckily the wall is short and there is a 12" overhang on it to protect it.

That's what caused me to mention this. It's those types of areas where it's done wrong a lot of the time. Overall, I love Hardie siding and highly recommend it. But like everything, it has it's quirks that have to be dealt with.

My neighbor has a modest sized house that's around 1,300 square feet. The contractor that built it said that they used a dozen Hardie saw blades to cut the Hardie, and charged him $50 for every blade. I can do several houses with a single Diablo Hardie Blade from Home Depot, so we got to looking around at what else they over charged him for. It wasn't good.

Flashing… I have a different problem on a build I did 40 years ago with 20 year comp shingles.

The shingles are fine but my flashing from the roofing supply has rusted through.

It’s protected but I’m certain acacia tree leaves caused the metal to rot.

At one time I had several siding arbitration cases and for each the manufacturer proved at the site inspection numerous defects of the installation details…

The homeowner was going after the manufacturer but the reality of the 3 I inspected is the siding crew totally disregarded manufacturer installation requirements.

No gap and in other places caulk instead of flashing and failing to follow fastener schedule…

The most blatant was a small area with no felt or house wrap… just siding on the studs covering bat insulation…

Flashing is such a huge pet peeve for me. I make money from roofers cutting this corner.

A person hires them for a new roof, but they never put in writing that they must use new flashing, and install new flashing all around the entire house. Now with everyone using Synthetic Underlayment, it's becoming common to see it not going to the edge of the roof. For some reason that I haven't figured out, they are rolling it out an inch or so short of the decking, and then not installing drip edge flashing. The jobs that I'm getting are from the Fascia and Soffit rotting out. It's becoming more and more common.

If you don't have drip edge flashing on your roof, water will travel under the edge of the shingle, and then between the plywood or OSB decking, and into the soffit cavity.

The roofer saves a couple hundred dollars, and the home owner pays me thousands to fix what they caused to happen.

Yep! They are installing drip edge flashing throughout as well. I will be keeping a vigilant eye on their process to make sure they do not cut any corners.
