Over Cladding Garage Roof

Leaving the exiting roof material in place eliminates the need for expensive removal actions whilst the over cladding exercise will also eliminate the risks associated with asbestos exposure.

Over cladding garage roof.

The garage doors were clad in the same material to help them match and their deep inset provides a deep shadow. This course of action causes minimal disruption to business activities and also provides added insulation to the roof construction. As the weight of the system is less than that of the potential water absorbed by the existing asbestos cement and fibre cement sheets there is no requirement for structural calculations. The typical thickness range for sheathing is 3 8 to 3 4 inch.

Will be in which incredible. The first stage is to fix a framework to hold the metal sheets in place directly to the purlins underneath the asbestos cement roof sheets. Start at the opposite end to the prevailing winds again and allow overlaps of 125mm. 8d ring shank nails should be used instead.

The process when overcladding an asbestos cement roof it will also be necessary in most cases to include a layer of insulation to meet current day building regulations. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame. Complete peace of mind. If you believe thus i l l explain to you.

Never attach roof sheathing with staples. Verges can then be created by using a ridge piece or alternatively nailing the final corrugation over a raised barge board. This is so frequent that some contractors make a living solely fixing cut edge corrosion which can occur very quickly on a metal roof. Filon over roofing is lightweight yet strong and is manufactured to the same profile as the existing roof.

This creates a risk since over cladding contractors often say you don t need to empty your garage and with all this drilling you may contaminate the contents with asbestos fibres. Now this is the 1st graphic. Once the sheets are fixed into place you can install the ridges. In order to do this any over cladding must have so many anchors bolts fixings down into the beams below the cement asbestos roof sheets that there will be a considerable amount of drilling of the existing asbestos cement roof sheets.

It therefore requires no additional structural supports. Install ridges and verges. As metal sheets an over clad is highly likely to develop rust and corrode from the inside meaning ugly orange patches of rust start flaking off the edges of the roof. Think about impression earlier mentioned.
