My name is Jeremy Allen, solar design tech here at Wholesale Solar.

Today we're here to discuss one of the most important parts of your solar array, the solar

We're gonna go over the installation of the IronRidge XR100 racking system on an asphalt

composition roof using the FlashFoot 2 flashings.

There are many other types of roof this is the most common, but if you have a tile or

metal roof don't be afraid, we do have a solution for you.

We choose to work with the IronRidge racking system because of its ease of installation,

code compliancy, and included state-stamped engineering that will include your wind and

snow load requirements specific to your state.

Before we jump on the roof, be sure to have all of your tools prepared, your parts laid

out, and the engineering report that we've provided you with so that you know how to

I do wanna make sure each one of you is being safe up there.

You can get a fall protection kit from your local hardware store or roofing supply store

One of the pieces of information that is not included on your engineering report is the

distance between the rails up on the roof.

That's gonna be dictated by the holes that are pre-drilled on your specific panel.

In this case, we've got a solar panel here, about 100 watts, its holes are gonna be 35

That means the rails on the roof are gonna be 35 and a half inches apart.

To get started, we need to find out where our rafter or truss is within this rooftop.

Now, keep in mind some local Authority Having Jurisdiction or your local building department,

may require you to have full three feet or more from the edge of the roof.

In our case, we don't have that much roof, so we're gonna go right up to the edge of

Where we're gonna wanna start out is finding nails if we can in the facia, or on that nice

pretty board that goes along the bottom of your rooftop.

In this case we can see a couple nails and we know generally that that truss is gonna

We don't need to know that exact space yet, because we're gonna drill a spot hole through

the roof and into the attic so we can measure exactly where that is.

The other figure we wanna keep in mind is the 35 and a half inches that we discussed

earlier, in this case we'll see, doesn't line up exactly with the center of our shingles,

And as long as we're within two to three inches of those pre-drilled mounting holes on the

So we're gonna know, we're gonna go in the center of this shingle length right here,

and the center of this shingle length right here.

So first thing we're gonna wanna do, we're gonna wanna get our drill and we're gonna

wanna drill right close to this to see how close we actually are to that rafter.

Alright, so the first thing we're gonna do is we're gonna put a pilot hole in here.

And again, we found our truss location somewhere in here and we know we've gotta be somewhat

centered on this course of shingles so we're gonna go ahead and put a hole right here and

Now we can leave the drill bit in place so that we can go into the attic and find out

where we are in comparison to that truss.

At this point we're gonna come into the attic space and measure from the center of our drill

bit to the edge of our truss to find out exactly how far we have to move over.

And we see we've got about one and five eighths inches.

We've gotta another three quarters of an inch to that to be sure we're centered inside of

So let's go ahead and go back up on the roof and make that happen.

Alright so we know we're an inch and five eighths from the center of this drill bit

to the edge of the truss here so we're actually gonna mark out that exact measurement.

And know we've got the edge of our truss.

Now, from there because all of our standard lumber is gonna be about an inch and a half,

we wanna measure three quarters of an inch from that point to the center of what's now

Now you're asking, "You've got a hole in your roof!

We actually will just use a standard sealant, something like Henry's or whatever your roof

specific manufacturer requires and put it into this hole to make sure it stays water

tight and essentially, that flashing is gonna go over that hole to make sure it stays weather-proof

So from this step, we'll go ahead and remove our drill bit.

So now that we have our center mark here, we're gonna make another center mark for the

next one up, again 35 and a half inches from the bottom hole.

So we're gonna go ahead and measure, in this case we know we've got a good square structure,

may not always be that way, so there may be a couple trips into the attic to spot holes

to be sure you're hitting the center of your truss.

But in this case, we'll go ahead and move along and we'll find out we're about 27 and

three eighths of an inch from the edge of the roof.

Now I'm gonna take that same measurement up to this course of shingles we're gonna go

27 and three eighths inches up here and know we've got a line now that we can take with

our chalk and make a good visible line for future holes that we're gonna be drilling.

Now if you have multiple panels high or multiple panels wide, you'll just do this that many

more times to be sure you have all the holes lined up before you actually start drilling.

So we've got a good chalk block and we're actually gonna get in here, we're gonna chalk

out a line on here so everyone can see exactly where we're gonna be drilling.

And pretty simple now from here, again, as long as the framing's standard, you should

have about a 24 inch center-to-center line.

Your truss is typically your 24 inches from each other, but again, that's not gonna always

be the case so you'll wanna double check.

We're gonna go ahead and pull the tape measurer 24 inches over and know that should be the

So now we have our two trusses marked out where we're actually gonna be drilling into

The other thing that we need to do is actually get that line lined up here where our rails

So we're gonna take a measurement from the bottom of the roof to the center of this or

if you really trust your roofer and know that they made straight lines to begin with, a

lot of times you can follow their course of shingles and know you should be really close.

So if we did that right, we'll know these'll be our first few real holes that will hold

Now that we have all of our holes drilled, we're gonna get up underneath each course
