Contrasting Hip Roofs

 In the last couple of months we have been doing structural repairs on two hip roof two story houses.  Though of almost the same age and located within 10 miles of each other the builders employed two very different systems of framing to create what superficially appear to be similar buildings. In this post I will use the roof systems of these houses to illustrate the approach each builder took.

Tubbs-Reed house

 The first building and the more typical is the Tubbs-Reed house located on Swan Island(Perkins Township), Maine. Built for Major Samuel Tubbs in the first decade of the 19th Century, it is a plain but well executed center chimney plan house. The building measures approximately 28' x 36'.

Peacock Tavern

 The second house is the Peacock Tavern built in 1807 on the Brunswick Road in Richmond, Maine. This is a highly unusual two story plank frame house of center hall and original ell kitchen plan.The left bay of the house in this photo is a parlor and ballroom added probably within ten years of the construction of the main building.The dimensions of the main portion of the original structure is approximately 24' x 36'.

 The methods and quality of execution used in the roof frames of these buildings reflect two very different traditions, but I will let the details of the roofs speak for themselves. The roof of the Tubbs-Reed house is of rafter purlin construction and very neatly executed. The Peacock Tavern roof is common rafter and generally poorly executed.

 Both roofs are 6/12 pitch and have a framed overhang at the eaves. In the Tubbs-Reed frame all the rafters line up with tie beams which pass by and are nicely joined to vertically offset plates. In contrast the ties and plate at The Peacock Tavern are in the same plane vertically and the rafter tails are connected with 1 1/4" pegs. Only the truss and hip rafters fall on tie beams. Common rafters land on 3x4 flying plates that run from tiebeam to tiebeam. The hip rafters were apparently cut too short originally and have 1" boards sistered to them to make up the length.Common rafters are butt cogged to the ridge pole.
 Kingposts at the Tubbs-Reed house are through dovetailed and wedged. Peacock is a simple mortise and tenon with two pegs.

 In conclusion I am always surprised both by the continuity and quirkiness of the building traditions of our area. The differences illustrated by these two roof systems are obviously the result of builders approaching things from different traditions, skill levels and budgets of home owners. It's interesting to note that either by coincidence or as a direct result of the quality of the original construction the Tubbs-Reed roof is in beautiful condition, whereas the Peacock roof has obviously leaked like a sieve for generations.

accordion lath splitter

 When people find out I restore old buildings one of the inevitable comments goes something like: "you must find all kinds of cool stuff in the walls of those old places". The truth is finding anything interesting is surprisingly rare unless you're into rodent skeletons or outdated forms of insulation.
 That being said things do turn up, like this late 18th C lath splitter found sealed up in the cavity above a ceiling in an early house in Dresden, Me. The lath is 3/4" vertically sawn pine attached with 8d wrought nails.
 Accordion or splitboard lath was installed by nailing one end of a board then splitting , wedging, and nailing your way across an area to be plastered. In midcoast Maine accordion lath was used starting around 1790. Before then riven lath (lath split on all four sides) was used.

 The splitting wedge is made of white oak and very nicely fashioned. Oval in cross section and lightly chamfered on the strike end, it appears to have seen little use. I wonder if its owner ever realized where it disappeared to.
