Talk:Domestic roof construction

Untitled
There are several overlapping sections with Roof including commercial and non-notable sources that don't meet WP:RS. Are there trade industry publications and mainstream consumer articles that can be used instead? Flowanda | Talk 17:31, 21 February 2008 (UTC)

ctrs?
What does "ctrs" mean in the diagram? Mutt Lunker (talk) 11:56, 3 January 2012 (UTC)

If it is a bizarre abbreviation for centimetres, the figures seem way too big. Those figures but in millimetres might be plausible. Mutt Lunker (talk) 21:10, 10 September 2012 (UTC)
 * ctrs must mean "centers", measurements between joists and rafters are typically measured "on center" rather than to an edge. Jim Derby (talk) 00:08, 6 January 2013 (UTC)

Sense
I was going to have a go at the opening sentence:

"This article is about the type of roof construction that consists of footings and an outer weatherproof skin, as found on most domestic architecture."

but it seemed so obviously wrong that I'm wary of not having read it correctly! CPES (talk) 18:08, 19 September 2013 (UTC)

This article is so incomplete as to be wrong.
The typical new roof in residential construction from New England to Oregon (northern USA) is composed of: rafters. plywood or OSB (oriented strand board) roofing (these completely cover the roof (except at vents and other penetrations) (also known as the roof deck). sheathing (a water-resistant 'paper' or plastic sheeting, found in newer homes). underlayment (usually tar paper of various weights (thicknesses)). finally shingles. (ordered from bottom to top surface). I have seen some homes use battens OVER the roofing and sheathing (not sure whether underlayment was used, nor where). Please note that this is the overwhelming construction in homes in NA which experience winter. (I have no information about hot weather (California, Arizona, etc.) roofs, nor about hot & wet (Louisiana, Florida) weather roofs (which may also require wind shear compliance).) It is just not true that purlin, lath or batten construction is used, as far as I know (construction practices in the USA are regional.) Note that "sheathing" may also be used to refer to the deck, but modern practice includes a (plastic-fiber composite) sheeting over the wood deck. I have seen a very few decks composed of tongue and groove (on older construction). This is significantly different from the roof structures claimed in this article.40.133.176.137 (talk) 13:13, 10 July 2016 (UTC)
