Re-Roofing a log store
Next to our miniature garden shed is a log store erected by the
previous owners of our house. A simple wooden frame butted up to the back of a garage supporting a simple roof sloping away from the the garage wall. The roof appears to be some particle board (stirling) with a simple layer of roofing felt. The felt has failed and the board is approaching the consistency of wet weetabix (other breakfast cereals are available). The framework is fine, so I hope to simply put up a new board, probably with a couple of layers of decent felt. What board should I use? OSB? WBP ply? Something else? |

Corrugated asbestos cement is the traditional one, or these days that probably means Onduline. If you do want to board it, OSB is the stuff. However there are a couple of grades about and most builders merchants only sell the less water resistant of the two, so check first. OSB is quite resistant to moisture on its surface, but it does need to have the edges well protected. |

What about using some of that clear plastic corrugated roofing sheeting? I used it for a covered area I made at the back of our summer house several years ago, built on to the wind sheltered side and its still fine. It lets light in and some winter heat from the sun, so maybe would help logs dry out. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

Corrugated asbestos cement is the traditional one, or these days that probably means Onduline. if using onduline (or same from Wickes) pay close attention to the instructions re spacings of support timbers underneath - it will warp and sag if not supported sufficiently - I know as my woodstore is covered with it .... Lasting well though fairly grim to cut - I used a jigsaw with a large toothed blade - lots of "tarry bits" kicking about for a while after building... get the correct "mushroom headed" nails and rubber grommet washers (Wickes do packs) if you really want to keep the rain out....

If it's reachable, the extra brittleness in a few years can lead to broken panels. If you want clear, I'd go with twinwall polycarb these days. If you don't need clear, I wouldn't try and use clear. |

Much better transfer speed, but still backwards compatible? |

What's more in 100 years time it will have rusted away to nothing whereas the clear plastic or the Onduline or whatever will be in a landfill or a hedge somewhere. |

If you paint it with tar varnish every three years, in a 100 years time it will still be on top of the shed. |

From my reading of technical data online, the roof of the store is of such a low pitch that I doubt I'd get away with Onduline without putting a decking layer under it - the current framework was built for board and felt, so only supports the edges, basically. I think I'll have to go with OSB and felt. Thanks for the pointers. |

The dimensions are such that there's 0.5m overlap vertically, so no chance of water getting back up that. The adjoining roof of the same pitch is asbestos cement with about 50mm overlap and, if kept clear of excessive moss, has never leaked via the overlap. -- Peter.
