See our retrofit section for information on retrofitting loadmaster lightweight insulating concrete poured gypsum conventional steel deck and rigid insulation.
Retrofit deck on sloped roof.
If required steel posts and beams or sub purlins are first installed to form the structure for a new sloped metal roof.
A deck on a sloped roof requires a different approach to the framing underneath the joists.
When faced with the need to replace a flat roof many building owners find retrofitting a more viable investment and so they erect a long lasting low maintenance sloped metal roof.
Loadmaster can be used in both flat and sloped structures with all types of roof coverings.
Single ply roof manufacturers may also have minimum requirements for roof deck properties depending on how the roof.
A metal roof has recently been shown to have a service life of 60 years or more meaning it will likely last for the entire useful life of the building.
Also the slope could be increased to improve the aesthetics of the roof by adding hips valleys and color.
Roof deck framing unlike for decks at ground level doesn t entail a ledger attached to the rim joist of a house.
Depending on your needs retro master provides every element required for a retrofit including structural framing sub framing and your new metal roof.
The existing roof s physical footprint framing system and other rooftop conditions will most likely control the new roof s geometry.
2010 standard for steel roof deck has a total load deflection limit for steel roof deck at l 120 whereas ibc table 1604 3 footnote a stipulates a total load deflection limit of l 60 for structural metal roofing figure 6.
Loadmaster provides a complete roof deck system.
To 12 ga steel framing installed over the existing roof s framing members to create a sloped plane.
Once you have your beams in place everything above them joists deck boards balusters and handrails is the same as for any other deck.
These new roofs can be either low sloped less than 2 12 functional roofs or high pitched greater than 2 12 architectural roofs depending on the expectations of the building owner.
Retrofit roofing systems be it for aesthetics or improved weather integrity many building owners with flat roofs less than 1 4 12 slope chose to add a sloped metal roof to their existing building.
Metal roofs have been documented to perform well and have a long service life.
The slope could be increased to improve solar panel performance says david stermer director of engineering at metal sales manufacturing corp louisville ky.
A sloped retrofit metal roof incrementally extends the life expectancy of the building reducing roof maintenance costs.
Instead a pair of beams rest on supports called sill plates to create a frame for the deck.
The use of metal retrofit roofs allows the flat roofed buildings to undergo a transformation into a sloped roof building.
