Dry (no-mortar) roof ridge tiles
Hi,
Does anyone have any experience of these type of tiles? It just seems like a bonkers idea to me. Surely they'll let all the rain in and get blown off the first time there's a gale? Or am I just behind the times? thanks |

Dry (no-mortar) roof ridge tiles
We have them and so does my daughter they are actually fixed down with screws, ours have fixings that go between the tiles hers have screws going through the tile. I did not see exactly what our roofer did but I know he attached extra laths on the ridge as we have trusses and no ridge timber.

Not sure how they are secured, though. Other roofs in the street retained the original ridge tiles after being replaced with artificial slate. And on all, the mortar has fallen out in places. My guess is it would be better to use a lime mortar that allows some movement. Which you are bound to get in a roof. -- *I yell because I care Dave Plowman London SW To e-mail, change noise into sound. |

They are a problem though, if a roof ladder is used. They tend to get pushed sideways, and they are not strong enough to hold the hook with complete safety. They can't be walked on either. The combination of a clip-on ridge and slippery plastic tiles can make it impossible to access an aerial without access machinery or scaffolding. I've no idea what their lifespan is likely to be, but most plastic things do eventually deteriorate in sunlight. Bill |

Richard The fitting instructions specify one batten support at the apex of each truss, and to use stainless steel nails and screws. Knowing how cheapskate tradesmen work, how do you know if they have used fewer batten supports or any old nails that they had to hand ?. At least it is obvious from the ground if a row of ridge tiles have been properly bedded in mortar. If the roof has a hip then you have a three way joint between the horizontal ridge and the two ridges each side of the hip which still seem to need a fillet of mortar. The main advantage seems to be to allow continuous ridge ventilation. What is the lifespan of polypropylene exposed to UVlight ?. |

I keep a 1 li plastic jug by the water butts and it has to be replaced every 2 or 3 years. It gets direct sun for about half the year for a few hours a day. When I moved most of the waste systems outside I used push-fit in black as it's PP; solvent weld is OK. Also realised that solvent weld is better in compression fittings as it's a tad bigger and is tighter in the fitting - all the comp. that I have left (washing machine) is slack now. -- Peter.
