Wood Board Siding Profiles & Sources

Reader Question: can you help me find a match for this rounded-edge double tear drop or double ogee type wood siding?

I'm having the hardest time finding this type of siding, it's rounded at the bottom and near the top. Any help appreciated.

1930s most likely but may be later. we have two houses in the Vero beach, Florida area with this siding. - Anonymous by private email 2017/10/28

Reply: Wood Siding / Lap Siding Pattern Names & Sources

I have run into that problem during building renovations. The general name for this siding is "drop lap" siding, but it was sold in several profiles and at least three different widths, usually made of pine.

What I did for repairing several older buildings with this siding was to buy new drop lap siding that I used to replace from the ground up as needed, but not necessarily all the way up the wall.

The new cove-cut drop lap siding looks a bit different but it wasn't bad. The alternative would have been to buy something close and then modify it, or to make my own out of clapboards - most people would find that cost prohibitive if more than a small area needed replacement.

In the U.S. the cove lap siding form is still widely sold. But other patterns such as the double teardrop or double-ogee siding pattern shown below are more difficult to find.

  [shown below as a pair of siding boards] double teardrop profile yellow pine siding in 1x6 dimension that is closest to what you are seeking, in the tear drop profile lap siding pattern.

The 6" nominal width of these siding boards has a nominal size after milling and sanding of 3/4" x 5 1/2", which looks quite close to the siding in your photograph.

• Southern Wood Specialties in Flomaton AL http://www.southernwoodspecialties.com/drop-siding.html
• Or use an Internet web search for cove lap, Dutch Lap, German Lap wood siding and you'll see similar siding but no exact match.

Watch out: some of these suppliers have a minimum order quantity that can be a bit large if you are only repairing a small area. Others will sell by individual board but may have higher prices.

Also the board widths vary, typically they're 6" or 8", and the head lap may need to be adjusted at the course that meets up with the older existing siding you plan to retain.

If you have to make a closer match to your specific siding you might consider modifying these Dutch Lap boards.

But first ask the wood siding suppliers if they have double ogee or double tear drop wood siding in the width you need. Yours is pretty narrow, about 5" or perhaps 10" wide.

You can also hire a lumber miller to make custom profile siding but in my opinion it's not cost justified unless you are restoring a historical building.

Popular Drop Siding or Lap Siding Profiles: It's not just shiplap

Synonyms for drop lap siding are Dutch Lap siding, Cove Lap Siding, German Lap Siding, and wwpa105 wood siding. But as you'll see from our examples of common wood siding profiles below, there has been and remains a wide range of wood siding profiles.

Many of these wood siding profiles have popular names that we will provide but others are designated by the Western Wood Products Association (WWPA) by pattern number.

An extensive catalog of wood siding profiles is in a book of standard patterns by the WWPA, and the wood siding profiles shown here are adapted from that resource, cited just below.

In the WWPA's siding profile catalog the association gives precise measurements that permit millers to produce these standard siding profiles. You will find shiplap siding in several variations among these profiles but in the company of coves, grooves, and bevels that extend the range of profiles.

Above: Beveled Shiplap Siding in a thick board design also referred to as Beveled Rustic Lap Siding

Basic Beveled Siding is milled in various thicknesses and with additional names such as Bungalow or Bungalow Colonial Siding, and a shiplap-like beveled Dolly Varden Siding

Above: Channel Rustic Siding. This variation on pure shiplap siding will reveal a 1 1/4" deep flat groove at the top of each siding board. In my OPINION this siding is less weather resistant than similar patterns that bevel exposed horizontal edges. [DF]

Above: Corn Cribbing - not a typical siding board you are likely to find on homes, but a wood board cut to drain and ventilate corn cribs.

Above: Cove Cut Lap Siding, also widely-referred to as drop siding though in fact the term "drop siding". In the right-hand profile in our sketch you can see the most-common simple cove cut at the top of this siding board.

Above: Double Ogee Siding - this is the siding profile that is the closest match to the siding sought by our reader above. This pattern is often called double teardrop siding. Also referred to as German Lap Siding or "German Siding" and possibly as Dutch Siding.

Above: Log Cabin Siding - rounded at top and bottom to resemble logs. See SLAB SIDING LOG HOMES for an example of a building where we installed this pattern.

Above: true Shiplap Siding, in its simplest, most-basic form. Shiplap siding milled into this pattern is sold in varying thicknesses: 3/8" lap, 1/2" lap, 2-shiplap (1 1/2" thick), 3-shiplap (2 1/2" thick) and 2-shiplap EV1S that includes bevels to give a 1 1/2" thick board similar to the V-Rustic beveled shiplap that we will show further below.

Below: three variations of Beveled Shiplap Siding Profiles including two T&G type profiles and in the center of our sketch, a traditional, double-beveled shiplap profile.

Below: V-Rustic Siding, another form of beveled shiplap wood siding. Some sources refer to this pattern as Novelty Siding - using an angled cut near the board top or top and bottom (as shown).

Above, second image showing V-CV-Rustic siding like V-Rustic but produced in a double-board version with a 3/4" V-groove milled in the board center.

Not shown here: figured novelty siding that includes a smaller rabbeted cove near the siding head.

Where do I find 104 Double beveled wood lap siding - On 2020-05-10 by Dale

Apologies, Dale, I don't recognize the term "104 double-beveled wood lap siding" - the "104" seems to be a tripping point. Maybe you can offer some details.

There is a #105 Cove siding - seen in this siding profile or siding pattern guide from OrePac a vendor of cedar siding foundf at orepac.com
