I have a narrative for when roofs are racked. I use it a lot here in Richmond, but I have never seen a roof leak from racking. Do you guys report on racked roofs?

I don't refer to it as racking in my report, however what I do write up is a lake of drip edge or improperly installed drip edge, I'mproperly installed starter row, improper roof jack installation, valley shingles not properly sealed, shingles improperly nailed/improper placement of nails, nails over driven, missing kick out flashings, improper roof/wall flashings, missing crickets/Saddle, etc, etc. well u get the idea. My roof reports are fairly lengthy.

I have down thousands of inspections (over 10,000) and as of today I have only ever found 8 roofs properly installed

No i dont write the shingles are racked, if they are racked and all the nails are properly installed and the all other components are as well, does installing the roof in a racked fashion effect the roof?

I use lots of installation pics on the roof inspection and most of my roof inspections have so many things wrong that adding the shingles were installed in a rack fashioned does not matter. See pics, you get the idea.

Vertical one-column racking is allowed in many roof manufacturers installation instructions.
Two-column vertical racking is not recommended by most of the same. Writing it up without verifying the allowable methods of installation may lead to issues.

lol. NVM Dude, not sure what that is about??

You asked the question I gave you an answer, do you know why they don't reccomend racking?? There is a couple of reasons but one reason is the fact it makes it hard to properly install the nails below the mastic line and install the 4-6 nails depending on pitch and wind loads. So with that said if you install in a racked fashion but you properly nail the shingles, properly install the starter row, drip edge and so on and so on what difference does it make? Fact is if you properly inspect the roof for many things I have listed you won't hardly ever find properly installed roofs. So I choose to write up everything that is improperly installed rather than stating the shingles appear to be installed in a raked fashion!!

This is what we use
Asphalt composition shingles covering the roof of this home were installed with joints aligned vertically at every other course. This installation method is called “racking”.
Racking is an improper installation method for many shingle types. It is acceptable but not preferred for some shingles types and is the required method for a few shingle types.
Baker Inspection Group recommends that before the expiration of your Inspection Objection Deadline, you have the roof examined by a by a Qualified Roofing Contractor to determine whether shingles have been improperly installed.

Ok, that is a little confusing and cotridictary in wording, I guess what I'm wondering is how many people inspect the roof and use something like this wording and then don't hit the issues that are caused by racking or other issues as I have stated above. I do not know of a single manufacturer that voids the warranty or prorates the warranty for rackin if properly nailed. As well I don't know of any insurance companies that voide a claim for racking but yet both intities will for some of the other issues posted earlier.

If the roof is racked but yet all shingles are nailed properly, flashing details are proper, drip edge is proper, etc, etc I have to ask what difference does it make??

Have you ever asked the GAF, or Owens Corning why they don't recommend racking?? I have and I have stated one of the reasons on a prior post. I don't have a problem with you choosing to write the racking and respect that you do, I just take it further and address all the issues that have occurred as a result but if all the issues above are addressed and the roof is nailed properly i choose not to write racked shingles. Good thing is in 22 yrs I have only seen 8 roofs installed properly so the racking is never an issue due to the fact I write the improper nailing.

If the shingles are installed with racked appearance but were installed using the step fashion you will still have the straight line joints but the shingles will be properly nailed so you have the appearance of racking but no issues from this will occur.

http://www.gaf.com/warranties_technical_documents/steep_slope_technical_advisory_bulletins/english_bulletins/racking_shingles_steep_slope_technical_point_tab_r_2011_123.pdf

An article on the internachi website said it can add to leaking but this is just not the case, when proper overlap/exposure is used the shingles will have 3 layers at the laps and the shingles will have 8-12 nails in each shingle 4-6 towards the middle of the shingle and 4-6 on the backside that is not visible.

Like I said racking is only an issue on most all shingle brands and stiles do to the lack of the last nail, look more at the nailing pattern and placement as a bigger issue more than the appearance of the non staggered joints. Pushing this off on a buyer to get a roofer out there is not doing them justice and is leaving you hanging out there when the roofer comes out and identifies drip edge issues, nailing issues, starter row, etc, etc if your not inspecting this.
