Choosing your roof structure style is a very significant part of designing the home. Some roof systems work better with certain floor plans than others.  Summit Log Products offers a wide variety of roof systems.  We have provided some simple drawings here to give you an idea about your choices. Keep in mind that many floor plans will accommodate a combination of two or more roof styles. Whether you are looking for the ultimate in roof design or going for a simple roof to keep the cost down, Summit Log can help you decide the best style for your home and desires.

Purlins create an open span but usually need to be supported by a wall or posts somewhere in the building. It is common to lay 2 X 6 or 2 X 8 tongue and groove over the purlins to create the roof strength as well as create  a tongue and groove ceiling. Purlins can also be made of timbers or glu lam beams. All are very attractive roof systems. (Requires Cold Roof.)



Log rafters with a log ridge beam is pictured here. The rafters are commonly overlaid with 2 x 6 tongue and groove to add structure, support and create a tongue and groove ceiling. Rafters may also have a glu lam ridge beam or a timber beam.  The ridge beam will likely need to be supported by a post or wall somewhere in the building.(Requires Cold Roof.)



Pictured here is a timber rafter system with glu lam ridge beam. A timber beam may also be used for the ridge beam in this application. 2 x 6 overlay is the common method of building the roof structure and again, will most likely require a post or wall support somewhere in the home.(Requires Cold Roof.)


This is a standard log truss. Summit Log uses a log for the kingpost instead of metal rod. This style roof system is also commonly  overlaid with the tongue and groove to complete the structure and create the tongue and groove ceiling. In most cases, the truss will clear span the home and will not need additional posting or walls for support. This style truss can also be made with timbers.(Requires Cold Roof.)



These trusses can be made from log or timbers. Note how the center is open. These trusses are common in loft areas to leave a “walk thru” for loft floor space. Here the tongue and groove would be applied to the bottom cord to create the loft floor and then again over the top of the truss to create the main ceiling and roof structure.(Requires Cold Roof.)



These trusses can be ordered from your local lumber yard. This is a common way to truss stick built homes as well as log homes.  Note the bottom cord will create a flat ceiling and may be covered with tongue and groove or gypsum board.


Here is another example of a truss that can be ordered from your local lumber yard, however the scissor truss allows for a vaulted ceiling and in some cases may be used for a loft application.



Gable ends are a significant part of the overall cosmetic look of the home. While many homes have a gable with large windows, you still have the rear gable and the dormers to consider. Here are some common choices.


The gable end of the home may be a continuation of log, or as pictured here, you can frame it up and cover it with matching Summit Log Channel Back Log siding.


This gable end is framed and covered with tongue and groove applied in a vertical pattern. Board and bat may also be used. Summit Log Channel Back Log Siding can be used for this application.


The diagonal sided gable end may be made of many different products. Tongue and groove, board and bat or cedar siding are common applications. Summit Log Channel Back Log Siding can be used for this application.
