Added by on 2017-10-27 for more FREE video tutorials covering Structural Design & Loading This video elaborates the calculation of wind pressure acting on roof for the structure given in the example. Very first, the video shows the formula used to determine wind pressure on roof which is nothing but the formula that has been briefly described before in earlier videos- the difference is on the assessment of roofs external pressure coefficient. The contents and aspects of the handbook of Australian Standard for Structural Design [Table- 5(B) & 5 (C)] have been used to evaluate different factors and parameters to determine the wind pressure acting on roof for the given structure. The video shows the influence of different factors e.g., roof slope, roof pitch angle, roof height and wind direction angle on the assessment of roof external pressure coefficient (Cp,e) in greater details. On hand practice is recommended to do with this video to understand the design procedure of wind pressure acting on roof fully for the structure given in the example problem.

    No – Android and iOS only. No plans for BB 7 and older.
    It will be available on PlayBook with OS 2, and BB10 phones … most likely will be added to Windows Phone 8

    Hi Dknightluvr

    There are 3 different places to make adjustments:

    1) The main screen where u specify actual roof details (pitch / size / tear-off, etc)

    2) General settings, where you change how much you charge for different types of work on the roof (tear off / chimney flashing / difficult roof add-on / plywood install, etc)

    3) Roof Materials – where u set prices for materials and INSTALL cost / sq for that particular material.

    Check all your settings and results should be similar. Thanks!

    @bretter66 –

    This app was made by US roofer for US roofers, and is based on squares / feet / 4×8 plywood / 3 bundles per square shingles, etc … the app is made primarily for roofers installing asphalt shingles in USA

    You don't have to buy it, but don't say you wasted 20 bucks – the videos show exactly what you are getting, before you buy – there are 6+ videos that walk you through the app, showing every aspect – and if you failed to watch them – don't complain now.

    @trytocleanit Button for slate? you can create the slate profile – an option we built in for contractors, knowing there are different roofing materials you can be installing with different specs . Watch Part 3 of this video, that goes over roofing materials profiles.

    Also there is no need to post same comments on multiple videos.
