What are tails in construction?
Rafter tails are the exposed exterior portion of a building’s wood structural truss that projects beyond the perimeter wall of the structure. This structural element is secured to the top of the wall or tie beam and then projects to support the soffit overhang.

What are rafter tails? Rafter tails are the exposed exterior portion of a building’s wood structural truss that projects beyond the perimeter wall of the structure. This structural element is secured to the top of the wall or tie beam and then projects to support the soffit overhang.
What is a rafter in construction?
A rafter is one of a series of sloped structural members such as wooden beams that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed to support the roof shingles, roof deck and its associated loads. A pair of rafters is called a couple.
What is a rafter vs truss?
Quick Overview of Trusses Vs Rafters. Both rafters and trusses provide support to the roof and are triangular in shape and structure. Containing two main outer beams, rafters support the roof structure. Trusses, on the other hand, give a vaulted ceiling look and do not create a feeling of an open ceiling.
What is construction pitch?
One of the most commonly used terms in roofing. Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
Can you cut off rafter tails?
Cut each rafter tail at the cut lines, using a circular saw. Once cut, the rafter tails are ready for installation of the fascia boards and roof sheathing.
How do you protect a rafter tail?
Best you can do is:
- sand them to bare wood.
- drill and insert boron rods maybe 1″ down from the top surface.
- plug the boron rod holes with epoxy and sand again.
- soak the end grain with a borate solution.
- soak the heck out of the entire exposed surface in an epoxy solution (I like CPES for this)
- restain with solid body stain.
What is a purlin in construction?
In steel construction, the term purlin typically refers to roof framing members that span parallel to the building eave, and support the roof decking or sheeting. Purlins are most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.
What do roof rafters sit on?
In a sloped roof, common rafters run from the peak of the roof down to the top of the exterior walls of the building. At the peak, the rafters are nailed to a ridge board, and at the top of the wall, rafters are attached to the horizontal top plate of the wall framing.
Is it cheaper to use trusses or rafters?
Trusses are lightweight engineered units consisting of top and bottom “chords” supported by a webbing of lumber in a triangle shape. Because they’re pre-made to your building specs offsite, often via automation like computer-driven saws, they are much faster and cheaper to install than rafters.
Is it OK to cut a roof truss?
Home owners should avoid cutting or modifying their roof trusses. These trusses are usually engineered by a structural engineering company to carry a specific roof load. When a truss becomes damaged, cut or modified there is a chance of a structural overload or that they will not perform properly.
What is the most common roof pitch?
between 4/12
Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.
Which is the tail event of a project?
We also know the ‘tail event’ from where the activity emerges and then terminates to another event the ‘head event’ and the head event is the tail event of another succeeding activity till we reach the END of the project schedule.
Can a conventional tail be teamed with a vertical tail?
Spin characteristics can be bad in the case of a conventional tail due to the blanketing of the vertical tailplane (Fig. 9.3). The downwash of the wing is relatively large in the area of the horizontal tailplane. Rear engines cannot be teamed with conventional tails. Stabilizer trim is possible with comparatively low complexity.
What do you need to know about tail coverage?
Definition. A provision found within a claims-made policy that permits an insured to report claims that are made against the insured after a policy has expired or been canceled, if the wrongful act that gave rise to the claim took place during the expired/canceled policy. Tail coverage requires that the insured pay additional premium. For…
What can a rafter tail be used for?
A rafter tail can be used typically in the overhang or soffit system of a home replicating the look of a traditional roof decking support. Depending on where it is used on a home, it can also be used as an Outlooker, Outrigger, Lookout, or Tailpiece.
