The trench cut (otherwise known as strip ventilation) is a long narrow ventilation hole that acts as a fire break on the roof of a structure that is being attacked by fire. This tactic is used. The sequence of cuts to create the ventilation hole should be a well-rehearsed dance based on department SOPs or the company officer's preference and experience Vertical ventilation is the removal of super-heated air, gases, smoke and pressure inside a closed or vent limited structure by cutting a hole in the roof. When vertical ventilation is coordinated. Ventilation is one of the most critical functions performed on the fire ground. There are times when it may be the single most important duty we accomplish. Early and effective ventilation of a structure fire draws heat, smoke, and toxic fire ignition of roofing material over a concrete slab

  2. As much as I love partner saws, my tools of choice on a peaked roof or any roof, is an axe and a 6-foot hook. Sure the saw will cut quicker but an axe and hook are more reliable. Do a proper size up and use any features of the roof to assist with venting such as taking out a skylight, and/or removing vent stacks etc
  3. This can be quite tricky when trying to make the standard 4 ft. x 4 ft. or 4 ft. x 8 ft. opening. In light of these facts, the Triangle Cut is a faster and safer method that can be utilized.
  4. 1. Attach 4-6 centering rafters and lift the ridge beam into place. The first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof. Place the 4-6 common rafters in their designated positions along the 2 longest walls, and nail them firmly to the wall with a nail gun

Room and pillar (variant of breast stoping), is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, rooms of ore are dug out while pillars of untouched material are left to support the roof overburden.Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of. roof water-tight since they are exposed to the weather. 12.2 DESIGN AND CONSTRUCTION OF FLAT ROOF The proper design of falls in a flat roof is an essential consideration in the overall drainage of the roof. Falls create flow paths to direct the drainage of rain-water away from the roof to suitable discharge points These parts are positioned where the pipe run meets the ceiling. Manufacturers often suggest you nail a piece of 1/2 to 3/4 inch OSB across the opening. You'll also need a hole cut to the size of the firestop. Then, nail or screw the fire stop into position. Continue the assembly and bracing sequence as you pass through the attic or second floor finish. Always be aware of your position on the roof relative to any roof openings, roof edges, co-workers, and penetrations. Installing metal panels or flashings on a windy day can be dangerous and should be avoided if possible. Cutting Aluminum Panels To make a cut parallel to the ribs, score the panel deeply wit

Do your research to make sure you include all of the required roof components. 4. Using power tools to conserve your mental and physical energy. 5 Attach the duct connector to the roof vent cap. Insert the connector in the hole, straighten the cap and trace the outline on the shingles. Remove the cap. Cut away the shingles just inside the outline following the manufacturer's directions. Cutting inside the outline will leave a little bit of overlap of the roof cap Avoid cutting the vent hole between your primary and secondary exits off the roof. When cutting your ventilation hole, a good technique to use is the 798 cut. This is a 3-by-3-foot hole that can. The flashing shall be a minimum of 4 inches (102 mm) high and 4 inches (102 mm) wide. At the end of the vertical sidewall the step flashing shall be turned out in a manner that directs water away from the wall and onto the roof and/or gutter.. While this is a nice diagram of how these flashings work don't forget our 5 th design rule

Step 4 - Cut Overhang. Set your circular saw to the correct depth and angle for cutting along the edge and saw off the excess overhang. Repeat this process for each slope of the roof. Sheathing your roof is as easy as 1,2 3, 4!

  5. Cut a 50 mm (2″) triangle off the top corner to direct water into the valley and embed the valley end of each shingle into a 75 mm (3″) band of asphalt plastic cement. It's critical to flash around plumbing stacks and attic vents because they are the most common roof penetrations

If you hit a stack, vent, or chimney, interlace the shingles with the flashing to allow water to run down the roof. When you reach the peak, either bring the ridge edges together with a ridge-capping layer or cut regular shingles into 3 tabbed, equal pieces and bend them so they fit on the roof peak Systems View of Ventilation • Tight construction both requires and allows good ventilation • Compartmentalization, the construction of airtight individual compartments, breaks big forces (stack, wind) into smaller forces. It's also important for unitized ventilation Other Roof Trim. Roof trim includes the flashing for the eaves and gables. It is secured every 10 inches along the eaves and roof gable. Another part of installing the roof trim is setting in the pipe vents and their flashings.These elements should be in place prior to placing the shingles so the shingles can be installed properly around them not require ventilation air during occupied times. economizer systems are not always less expensive than return fan economizers. In a unit with an exhaust fan economizer the supply fan has to over come the return air pressure drop, which may require a larger supply fan and supply fan motor than a comparable return fan system

  1. If you need to re-roof your house, put on slip-resistant shoes and a safety harness, and start removing the tiles from your roof. Pry up the nails, and frequently stop to shovel the old tiles into a large trash container. Remove the metal flashing around chimneys, vents, and valleys in the roof and sweep the roof when you're finished
  2. The vent size is important. Ridge vents should be about one-fourth the floor area and the side vents about the same size. The roof vents should open above the horizontal position to provide about a 60-degree angle to the roof. Most of these vents are manually operated. References. AMCA
  3. If you live in a high-wind zone, use 6 roofing nails per shingle instead of 4 for added security. 3. Keep nailing shingles up the roof, overlapping each course with that below. Look for the white or pink center line on the bottom shingles and overlap the next row right up to that line
  4. Install the second course just like the first, using the guidelines on the underlayment to get the correct overlap. When an ice dam forms on a roof (usually caused by poor attic insulation/ ventilation), ice and water can work their way up under the shingles and leak back into the house.Also, strong winds can blow rainwater under shingles

Roof ventilation. Ventilate the roof space where possible to allow built-up heat to dissipate. Even in cooler climates a minimal amount of ventilation is desirable to allow built-up moisture to escape. Air gaps along the ridgeline or between tiles often provide sufficient ventilation. Gable or eaves vents may also be used Joist filling should be: 12mm below the top of flat roof joists to allow for timber shrinkage. the recessed portion of timber joists should be treated. checked to ensure the cold roof ventilation is not blocked. Clay bricks and concrete blocks should not be mixed. Where a different size of masonry unit is needed to ensure correct coursing. 14. Use floor to ceiling loft storage for a practical space.
