Stratco can fold a wide range of standard or custom flashings to suit your requirements. Flashings are available in prepainted steel, zinc/alum, aluminium, stainless steel, and copper.
Ordering Flashings Information
Receiving Flashing Orders
Our preferred method of receiving flashings is by fax or placed using Stratco Direct®. Stratco will accept, but take no responsibility for orders placed by phone.
Standard Flashing Drawings
All standard flashing drawings are shown as non-tapered, however can be ordered as tapered flashings using the “Ordering Tapered Flashings” details outlined below. Letters describe the dimensions of each plane of the flashing, and numbers describe the angle. You will need to advise us of all dimensions, and identify any angle which is not 90 degrees.
Ordering Tapered Flashings
Tapered flashings use the same description system as non-tapered flashings. Angles will always be constant throughout the flashing. The dimensions closest to you described as “NEAR” (as shown in the drawing) have a “1” added to the letter representing the dimension, and the dimensions furthest away described as “FAR”.
Clock Method For Phone Orders
Commence at the centre of the clock. Draw a straight line from the centre to the number on the clock (1-12 ) at the required angle, representing the first line of your flashing drawing. Where the pen stops becomes the centre of the clock for the next line. Complete the flashing using this method. For tapered flashings quote near edges first. Repeat for back (use same letters) unless otherwise indicated.
The page method describes the flashing as it is drawn on a page. Commence drawing the flashing at the centre of the page describing the direction of the line as you draw it, advising if the line moves vertically up or down the page, horizontally left or right, or to which corner of the page. Also advise the length of the line. Do this for every line in the flashing, advising of any included angles.
A square or rectangular gutter that is used within the boundaries of the roof. It may be formed between a roof surface and a parapet wall or between two roof surfaces. Available with infold, outfold, splashback and squashfold edges. This gutter is usually supported on a box gutter board to improve strength & stiffness and to minimise damage caused by roof traffic.
A purpose made external gutter which is located at the edge of an industrial roof. It is usually supported by heavy gauge brackets that have been designed specifically to suit the industrial eaves gutter shape. When made in larger sizes special attention should be given to minimising oil canning of flat surfaces by introducing additional ribs into the design.
A shallow gutter formed to suit the angle between two internal slopes of a roof. Its design will usually include a return at each edge to minimise the possibility of water spillage into the roof space. Depending on the size and application additional internal stiffening ribs may be included.
A half round segmented gutter formed into a trough. It is formed between a roof surface and a parapet wall or between two roof surfaces and is available with infold, outfold, splashback and squashfold edges. Usually supported by heavy gauge straps, trough gutters are very efficient and have better self cleaning properties than box gutters. In most cases the depth will not exceed half the width.
A folded piece of steel used for waterproofing wall sheeting where two walls meet to form an external corner. Where used with steel sheet walling it should lap at least one rib and a recommended two ribs for maximum water proofing.
A folded piece of steel used to prevent water from penetrating the space where a vertical surface intersects a roof. Where used with steel sheet roofing it should lap at least one rib and a recommended two ribs for maximum water proofing. Wider apron flashings are advised when the base of the flashing faces into the prevailing wind.
A folded piece of steel used to finish the base of a vertical surface, in such a way as to prevent water penetration. It also provides an edge to an adjoining soffit. Typical applications are in facades and to finish overhanging canopies. The flashing also prevents water contact to the ends of sheeting.
A purpose made flashing used to seal the join between the end of a roof and masonry wall. A “V” groove end locates into either a preformed reglet, or a cut in the masonry wall providing a water resistant join to the roof and wall connection. When installed, pole plate flashings (often called chimney flashings) can either be stepped to conform to brick courses or left straight, for a more modern appearance.
A steel covering over the ridge to provide a continuous cover and effective weather seal between two slopes. The size of the edge break should conform with the rib height of the steel roofing to which the ridge is attached. Good roofing practice is to notch this edge break to neatly fit around each rib of the roof sheet.
A covering used to waterproof and cap the ends of vertical sheets or masonry walls. A stiffening edge or break is often applied to the legs of the parapet cap for a more appealing appearance, and to minimise oil canning of the steel. Ensure that these recommendations are taken into account when measuring the flashing. It is also important to ensure that water does not pool on top of the cap, to prevent water seeping into the building.
A folded sheet used to waterproof the junction between a fascia or barge board and roof sheeting. The size of the edge break should conform with the rib height of the steel roofing to which the ridge is attached.
