Part Of Building Directly Under The Roof

I just didn t get around to doing the second part rigid insulation over the top of the existing roof deck.

Part of building directly under the roof.

Every part of a roof has a specific purpose to ensure protection of a house from the elements. 1 strip the shingles expose the deck install a fully adhered membrane and go to town with rigid insulation. This ensures complete coverage and gives the finished roof an attractive visual pattern. A composite decking made of solid materials it resembles real wood and particularly strong and stable for bearing heavy load.

It is attached directly to the decking along the bottom of the roof slope and above the underlay on the sides of the roof. Built up roof a low slope or flat seeming roof covered with alternating layers of roofing felt and hot mopped asphalt and topped off with a layer of gravel. Improper selection of the roof underlayment may allow. Cornice the wood or metal finishing at ends or edges of a building including a fascia frieze or rake.

Slope a roof s slope is the number of inches it rises for every 12 inches of horizontal run a roof with a 4 in 12 slope rises 4 inches for every 12 inches of horizontal run. Ridge the top peak of a gable roof running horizontally where two sloping sides meet. The metal roofing system and its expected service life the climate at the building location roof slope and geometry and ambient conditions temperature relative humidity within the building. This occurs on pitched roofs with sloping planes that join along their.

The pattern is begun in this manner. The space under the roof. The attic must be ventilated to protect the roofing system against excessive heat in summer and warm moist air generated by the house in winter. A horizontal timber or metal resting at the peak of the roof the rafters and trusses are connected to the ridge board for a cohesive framework.

Like a puzzle each part works with the others to enhance the strength and security of the roof while providing flexibility for design options. Counterflashing the flashing that is embedded or. I did the first part right. Starting on the left side of the roof at the eave place the first full shingle strip directly over the starter course at the eave and rake edges.

The spray foam in the cavities 17 years ago and the fully adhered membrane over the top. It is a waterproofing layer made of regular felt stacked above the solid. If the cavity between the rafters trusses is filled with insulation and is air tight like the walls you will need a vapour barrier. Long term in service roof performance can be affected by several important factors including.

The lower part of the roof. The same roof has a 4 12 or 1 3 pitch. A roof does get hotter than the walls in the summer but doesn t matter at least in colder climates. The roof primary structure.

Gable the triangular part of a wall where roof pitches meet and come to a peak. Hip a downward sloping junction of the roof where sloping sides meet.
