Dry Ridge

It's Fast

RidgeFast is the fast and easy way to install a ventilated dry ridge. The unique system is designed to simply roll out along the ridge and is far quicker than mortar bedding.

It's Universal

Thanks to a unique fixing system RidgeFast can be used with ail standard ridges, tiles and slates. The 6-metre roll is easily moulded to the shape of any tile or slate and the grey colour of the side flashing replicates a mortar finish.

It's Ventilated

Provides a minimum ventilated area of 5,000 sq.mm. per linear metre and is suitable for ventilating flat tiles. Specially designed blanking strips allow you to use RidgeFast with ridge and gas vent terminals.

It's Maintenance Free

The dry fixing method offers considerable advantages, not only in the speed of installation, but also in long-term economy and safety. If you would like to read below, it will explain all the advantages you would have on your property.

Maintenance free dry verge and ridge fast systems

The dry roof offers specifiers, designers and fixers the following benefits over mortar bedding:

Benefits include:

  • Mechanically fixed to resist the highest wind forces likely to occur in the UK
  • Maintenance - free
  • Allows all weather laying and fixing
  • Eliminates the problems associated with mortar
  • Quick and simple to lay and fix
  • Provides a consistent attractive finish
  • Provides continuous ventilation at ridge

ONCE DRY-FIXED, THEY STAY FIXED

Redland leads the way in the development of mechanical or “Dry-Fix” roofing systems to provide neat, maintenance-free and cost effective roofing solutions that will stay put no matter what the weather brings.

Our dry-fix systems eliminate the need for mortar bedding ridge, hips and verges, and have a number of advantages.

  • Fully tested against the elements to secure the roof in severe weather conditions
  • Eliminate problems of mortar failure due to poor workmanship
  • Maintenance-free
  • Quick and easy to fit with no special tools required
  • Can be laid even when bad weather is expected
  • Incompatible ventilation at the ridge
  • Compatible with most tiles and slates
  • Comply with BS 5534 requirements for mechanical fixing, and BS 5250 for ventilation


Like all of our products, the durability of our dry-fix systems has been extensively tested under all climatic conditions, from the UV rays of the blazing sun to sub-zero temperatures. They are also laid on roofs in our purpose built wind tunnel to assess their performance against the UK and Ireland’s most severe storm conditions. This thorough approach has enabled us to achieve Agrement Certification for the majority of our dry fixed systems.



Based upon our industry leading know-how we are able to guarantee that a complete Redland roof covering will remain secure and weathertight for 15 years.


EFFECTIVE VENTILATION

Good roof design does not just mean choosing the right tile or slate. The protection of the supporting structure form the harmful effects of condensation is equally important. The proven method for preventing condensation is through the use of effective roof ventilation.

Condensation in roof spaces has become an increasing problem for several reasons:

 Part L of the building regulations is driving up standards for the air tightness of dwellings at the same time as encouraging use of increased levels of insulation.

These changes in building standards – to reduce energy consumption – coupled with householders’ increasing use of appliances such as dishwashers and tumble dryers, have contributed to the increasing presence of water vapour in colder roof spaces.

BS 5250, Code of practice for control of condensation in buildings, sets out best practice recommendations for managing condensation risk in roofs and complying with Part C of the building regulations. Specification of the most appropriate form of roof ventilation depends largely on how airtight the ceiling is.

Broadly speaking, ventilation solutions can be divided into those designed for roof constructions with a well-sealed ceiling (Breathing Roof Solutions) and those where the ceiling airtightness is not as good (Traditional Ventilation Solutions). 

 

Well-sealed ceilings

With Traditional construction methods it is not possible to guarantee a completely sealed ceiling. It is also not possible to guarantee that the ceiling will remain sealed for the design life of the building.

With care over design and good workmanship, however, it is possible to achieve a well-sealed ceiling such that less ventilation is needed than provided by traditional ventilation solutions.

A fundamental requirement of Breathing Roof solutions is the achievement of a well-sealed ceiling. Failure to achieve this level of ceiling airtightness significantly increases the risk of roof condensation.

BS 9250:2007, Code of practice for design of the airtightness of ceilings in pitched roofs, describes both the detailed requirements include the presence of well-sealed pipe and cable penetrations including light fittings, in addition to a well-sealed loft hatch.

Redland’s range of breathing Roof solutions provide the optimum specification when a well-sealed ceiling is installed.
