Shiplap Siding

Ship Lap Siding is a type of Drop Lap siding with a tight "flush joint" profile. It is similar to tongue and groove but with a single over lap - usually 1/2" in depth but can me more or less depending on the width of the board 6", 8", 10" or the shiplap profile selected.
 
Ship-lap siding can be installed horizontally or vertically with the edge of one board having a recessed area which receives the shaped top edge of the board next to or below it, so as to exclude water during rainfall. In vertical applications, be sure to bevel cut the ends and install the shiplap siding so water is directed to the outside.
 
Shiplap is known for its ability to form a tight seal while allowing the wood siding to "breath" with changes in season and humidity.

Ship-lap Patterns


There are 2 standard Shiplap pattern profiles
 
1. Ship-lap Pattern: Square Edge
 
Shiplap Pattern - Square Edge
 
2. Ship-lap Pattern: Beveled Edge

"Shadow Gap" Profile

In the last few years a modification to the standard Shiplap "Flush Joint" profile has gained in prominance. Sometimes called Shadow Gap, Shadow Profile, Shadow Line, Small Reveal and "Thin Line" this is a custom milled shiplap profile that includes a narrow gap where the boards overlap. When installed a "shadow" effect is created.
 
The diagram below outlines the joins between the installed boards. "G" is the custom milled gap which can vary based on the "shadow line" emphasis the customer is looking for - but is usually narrow often only 3/16 - 3/8 inch.

Shiplap Siding TRUE Measure


You might be wondering why our Buffalo diagrams above have letters - A, B, C - instead of actual measurements. That is because siding measurements can vary from mill to mill and lumber yard to lumber yard. Using letters allows us to confirm the TRUE dimensions with the mill before we sell to our customers.
 
NOMINAL SIZES are for identification only. Even though a pattern is called 1x6" or 1x8" that does not mean it measures 1 inch thick and 6 or 8 inches wide. Nominal 1x6, 1x8 refers to the size before the pattern profile is milled and NOT the board's final finished or "dressed" dimensions.
 
A 1" NOMINAL is usually 11/16ths inch thick. A 6" NOMINAL shiplap pattern is usually 5 3/8 - 5 1/2" wide including the overlap which results in 4 7/8 - 5 1/8 inches of exposed face depending on lap depth. An 8" NOMINAL shiplap pattern is usually 7 1/8 - 7 1/4" wide including the overlap which results in 6 5/8 - 6 7/8 inches of exposed face depending on the lap depth. This is called the pattern's "exposure" - the visible part of the board when installed on your wall.
 
The Western Wood Products Association (WWPA) and California Redwood Association (CRA) diagrams below are industry pattern standards and display actual numbers but they are guidelines not milling requirements. Over the years milled dimensions have shrunk (and continue to do so). Once you have calculated your project's SQUARE FOOT area you need to get the true dimensions - especially the exposure - of the wood siding boards you are buying.
 
Read our Ship-lap SQFT to LFT Coverage and "Buyer Beware" warning   to make sure you ask the right questions BEFORE you BUY.

SHIPLAP SQFT LFT Coverage


Ship-lap patterns are often sold by the linear (or lineal) foot. To figure out how many linear feet (LFT) you need you must multiply the square foot area you plan to COVER by a linear factor based on the pattern width you have selected 6", 8", or 10". The Lineal Foot Factor is derived by dividing 12 inches by the individual pattern's "exposed" face - the width that is still visible after the siding boards are installed.


A) Calculate the square footage in walls: length x height = sq. ft.
B) Calculate, and then subtract, the square footage of openings
C) Add 10% to cover trim and waste = SQFT needed
D) Multiply SQFT result by the linear factor = LFT needed


BUYER BEWARE WARNING: The actual "dressed" widths and "Exposed Face" measurements below are suggested based on our experience in the industry. HOWEVER individual mills often have their own pattern standards which vary from the norm. When you get ready to buy be sure to ASK for the exposed width to make sure you are buying enough to complete the job!
 

SHIPLAP Siding Coverage Factors*

Nominal WidthDressed WidthExposed FaceLinear Ft Factor
6"5 7/16"5 1/16"2.37
8"7 1/4"6 3/4"1.78
10"9 1/4"8 3/4"1.37

* assuming 1/2" board overlap


Example of 1x8" Pattern Coverage estimation: If you are siding four walls 8 feet high by 40 feet long with 8" wide SHIPLAP boards and you allow 10% of the total square feet for openings, you would need approximately 2250-2350 linear feet:

SQFT AREA: 4 * 8 * 40 = 1280 SQ FT - 128 (10% openings) + 115 (10% trim/waste) = 1267 SQ FT

8" Ship-lap Pattern: 1267 SQ FT * 1.78 linear factor = 2255.3 LFT
