Redland’s Dry Fix system is one of the main reasons that Redland roof systems are so reliable –
but what is dry fix?
In lamens terms, its a mortar free way of fixing your roof! So how does the concept work?
In order to remain weatherproof, it is obvious that the roof tiles need to be securely attached to the roof. Roof tiles are 'hung' from the roof battens, with some (but not all) of the tiles being attached with nails. The tiles are usually hung in parallel rows, with each row overlapping the row below it to exclude rainwater and to cover the nails that hold the row below.
The verge and ridge tiles (ie the tiles at the edges) need more secure fixing. Traditionally these tiles were fixed using a mortar bed. Mortar, however, is not always a reliable solution. Difficult to get right in the first place, mortar is also liable to crack and crumble with age, leaving loose tiles and gaps in the roof that let rain in.
The National House Building Council (NHBC) is the body that provides warranties for new houses. In 2010 more than half of claims against their Buildmark warranties related to pitched roofing with the vast majority of these problems relating to mortar failure on roofs.
Consequently, the NHBC now recommends dry fix systems. As the name implies, dry-fix systems do not use mortar, but instead use mechanical fixings (screws and nails) to fix the tiles and associated weatherproofing. The result is faster, cleaner and more effective. That is why Redland’s Dry Fix is part of our roofing system.
