9.26.8.4.(1) | Application | Intent |
| OH1 | OS2 |
| Objective | OS2 Structural Safety |
| Attribution | |
| Application | Application 1: Cementing of the first course of asphalt shingles
on roofs having a slope of less than 1 in 3, on buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9]. |

| Intent | Intent 1: To limit the probability that shingles will not form a continuous
waterproof membrane, which could lead to rain or meltwater ponding on low-slope
roofs and penetrating past shingles under wind-uplift or hydrostatic pressure,
or capillary action, which could lead to water penetrating directly to roof
decking or sheathing, which could lead to deterioration, which could lead
to the structural failure of roofs or assemblies protected by roofs, which
could lead to harm to persons. |
