Flat Roof Condensation Solutions

Condensation isn t good news for a flat roof.

Flat roof condensation solutions.

Insulate and try to keep from reaching the dew point. Condensation is never good news for a flat roof. For example you can introduce vents by replacing some of the roof tiles. Vapor retarders are the true heroes here.

By inspecting your roof for signs of condensation and acting on implementing solutions to resolve it you ll save yourself the. For clarity flat roofs actually have a slight slope to allow rain water to drain off the roof but they seem flat when compared with more traditional steeply sloped roofs. Insulation also helps diminish condensation issues. Step 2 plywood roofing.

Climb on the ladder and use your hammer and crowbar to remove the tin roof from the wooden frame. The cold deck solution there are two forms of flat roof construction which can reduce the risk of condensation forming. This includes defects in the roof membrane leaks at penetrations at parapet walls and at any other flashings on flat and low slope roofs. It s designed to last decades but with problems like roof condensation moisture damage can dramatically cut even the best roof s lifetime short.

This helps to prevent moisture build up on vulnerable materials like wood or insulation. This is especially so if it occurs within the roof s structure itself as this can lead to decay in the roof timbers which is very difficult to spot. However vapor barriers a k a. Essentially thermal insulation can either be placed above or below the structural roof deck or waterproofing layer.

The real key to avoiding moisture and condensation problems in low slope and flat roofs though is to keep moisture out of the ceiling in the first place. Be vigilant about your roof. Add a preinstalled membrane to absorb and release the condensation as it forms with the natural weather cycle. The slope should be a minimum of 1 in 80 but in practice a minimum slope of 1 to 40 should be used to allow for deflection of the roof and for normal building tolerances.

Traditionally we ve insulated the roof panel to try and keep the temperature on the panel from reaching the dew point. It can also reduce thermal insulation performance which can be a particular problem during winter. When your roof is already in place there is unfortunately no direct or easy solution to the problem of condensation. If you get to it in time your tin roof should still be viable for you to use.
