ROOF SYSTEMS AND CONFIGURATION

A ROOF SYSTEM is the system of the interconnected components designed to waterproof and insulate the building’s top surface.

The functional requirement for roof includes wind resistance, fire, water, thermal insulation and energy conservation. The performance of the roof will much depend on the design quality, quality of materials, construction quality and maintenance frequency.

Types of roofing systems

# Low-sloped roof systems
# Steep-sloped roof systems

LOW SLOPED ROOFING SYSTEMS

Refers to the roofing system that comprises the water impermeable or waterproof layers and all the roofing membranes installed on slopes less than or equal to 14 degrees.

Low sloped roof systems consists of the following parts:

* Roof deck
* Vapour retarder
* Roof insulation
* Roof covering

LOW SLOPE ROOF COVERING

Is made of a weather proofing membrane that sheds water slowly to drainage outlets. low slope covering includes Built-Up Roofs (BUR) composing of bitumen either asphalt or coal tar applied hot, felts either organic, glass-fiber, polyester and a surfacing, such as aggregate, coating, or cap sheet.

Liquid-Applied Roof Coverings are applied over concrete or wood sheathing by using sprayer, brush, roller, or squeegee. Metal roof coverings provide moisture infiltration resistance at a certain pressure range. Modified Bitumen Membranes applied in single layer polymers used such as atactic polypropylene; APP. Other low slope roof covering are Single-Ply Roof coverings and Spray-Applied polyurethane Foam (SPF) Roof Coverings

STEEP-SLOPE ROOF COVERINGS

In steep slope roof systems water flows rapidly over the coverings to drainage outlets.

Materials used for steep roof coverings include asphalt shingles, cement fiber shingles, metal roof coverings and roof slates, synthetics and roofing tiles. Wood shingles and shakes which are wood roof made of wood species of high grades of shingles and shakes such as of cedar treated in pressure with preservatives and dried. For moisture protection and fire resistance.

CONSTRUCTION OF SLOPING ROOFS

The sloping roof systems are lean-to roof structures, Gabled end roof and hipped end roof. These systems can be made of either timber, steel or aluminum truss frames. The construction of trusses for these roof can be either simple, compound or complex truss system depending on the span, esthetics considerations and materials used in the construction.

LEAN-TO ROOF

Lean-to roof is a type of roof that slopes on one side the joists or trusses are made to lie on the other side of the roof.

[[File:2145 FP581567 webview.jpg]]

CLEAR STORY

This comprises of the series of clear windows made on the projected part of the roof.

[[File:Main roof 7.JPG]]

HIPPED ROOF

Is the type of roof that is pitched with slopes on all four sides which meet at the corners to form hips. Hipped roof may or may not contain a ridge.

TYPES OF HIPPED ROOF

gambrel roof

This is a hipped roof made with a ventilator at the upper part of the roof.

Jerkin roof

It is adopted when trying to reduce high hipped end.

Hipped mansard gable

This comprises of the side-cladding along the eaves used in warehouses and in domestic houses.

Gable roof End

Refers to roof with sloping sides that meet at meet at the central ridge. Gable roof can be either on one side or on both sides. Gable is the triangular upper portion of the wall at the end of a double sloping roof.

[[File:Gable.jpg]]

TYPES OF ROOF GABLE ENDS

Barge Board Gable

The commonly used gable type ensuring that the walls are completely covered.

Gable Roll

This comprise of a well designed roof end at the gable

Sloping Parapet Gable

To stop the wind uplifting effect to a roof, sloping parapet gable restrain the coming wind against the roof structure.

Parapet with buttress

For a neat division of the lean to roofs at the varying levels parapet buttress helps to improve the esthetics of the building.

Parapet Cape

Parapet cape helps to give a simple less detail roof gable end

Tudor Gable

This is framed gable either in natural wood or plastered to look like wood and painted

Contemporary Gable

Stylish with beam and painted in more than one colour the gutter fixed behind the wall.
