Roof pitch defined and explained.

Shallow roof pitch loft conversion.

Below are a few solutions that allow you to convert shallow lofts. Where you re adding a large dormer. Our current flat roof is 70cm below our bathroom window. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12.

Or the colon can replace the slash as in 2 12 or 7 12. Shallow roofs are particularly difficult because there isn t enough headroom so even adding large dormers won t actually add much room to the internal space. But it is pretty simple if you choose your loft converter properly. A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

Pitch is the term used to describe the angle slope or slant of your roof. He was going on about a 9 degree pitch not sure if he was exaggerating though. Sometimes pitch is also expressed in. Hip to gable loft conversions are most commonly found on the side of either end terrace or semi detached houses.

Most loft conversions employ at least one pair of steel beams to support the new floor structure and the roof slopes at purlin level and sometimes also at ridge level e g. You have three options of varying cost and out comes. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.

If the lack of headroom is critical the obvious solution is to remove the existing roof and replace the original structure with a larger one. Loft conversions in homes with low pitched roofs have always been a bit of a taboo. However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof.
