FAQ'S ROOFING

Roofing

Q1 - What is the minimum finished fall for a flat roof?

A1 - The minimum finished fall is 1:80. However, to ensure that this fall is achieved, allowance should be made for construction inaccuracies. Generally, falls of twice the minimum finished fall should therefore be assumed for design purposes.


Q2 - What is a cold roof?

A2 - This is also known as cold deck. The thermal insulation is placed beneath the structural deck, and above the ceiling. To reduce the risk of condensation, cross ventilation should be provided above the insulation.


Q3 - What is a warm roof?

A3 - This is also known as warm deck as the thermal insulation is placed above the structural deck. This form of construction is the option most frequently used in the refurbishment and new build flat roofing markets as it eliminates need for ventilation. Additionally insulation may also be used to increase the thermal properties and/or supplied as a tapered scheme to enhance inadequate falls on an existing flat roof.


Q4 - Do I have to worry about maintenance of my new roof?

A4 - Maintenance of a roof is extremely important, as it ensures the life expectancy of the roof is maximised. The roof should be inspected at least once a year and preferably twice. Once in March and secondly in November. Typical items for inspection include, clearing gutters and outlets of debris, checking the condition of upstands and flashings; checking for loose laps, edge trims and faulty penetrations and loss of surface protection.
