Are garden timber cabins rainproof is a query we got asked all the time here at Timberdise.
The short simple answer to your question is an unqualified yes!
Why would they not be?
Well,let’s take a look at some of the possible troubles with a timber cabin which would make the timber cabin not rainproof and fairly frankly not fit for purpose.The main thing to look at quickly is the roof structure,that’s where you would imagine the main problem would start (this is not always the scenario but that’s where we will start today). The main problem with the roof structure would be to have the felt or roof shingles to not be placed appropriately. This is fairly easily done if this is something you have never done before and why it should always be tackled by a professional most especially if you are putting in a lot of your hard earned cash on a timber cabin.
• Make certain that the overlies are overliing in the proper way. You should always start felting at the bottom of the building and felt upwards. By doing this you ensure that the felt overlies on top of the piece of felt that is further down the roof structure. This will ensure there is a natural run off of the water,if you start felting at the top of the roof structure and you put the overlie from the bottom pieces over the top of the felt higher up when the rain works off it will operate under the felt and therefor result in a leakage. This is just exactly the same when doing shingles,make certain you set up from bottom upwards.
• Make certain the overlies of the felt/shingles are fairly generous. You don’t want them to be just barely overliing because this could result in rain to get between the felt sheets and this will result in a leakage
.• Make certain you use plenty of felt nails. Ideally you want to be spacing the felt nails around 6 inches apart from each other. Always do this on both sides of the felt and dependent on the quality of the felt you are using possibly put another row of pin in the middle,possibly two rows but again this depends on the quality of the felt. Failure to put enough felt pin in there could result in the felt blowing off during a bad storm which would then leave your building subjected to leaks.
• It is in addition crucial that when you reach the overhang of the building with the felt you pin the felt to side of the roof structure but DO NOT tuck the felt under the overhang of the roof structure as this limits the natural run off of the water. This can result in premature rotting of the building and in some scenarios result in the roof structure to leakage around the top corners of the building as water could build up.
• Make certain you use the right size fixings. If the roofing boards on your building are let’s say 10mm,you don’t want felt nails of 16mm. Doing this would result in the felt nails to come completely through the roof structure. This would not look cosmetically appealing and would in addition be a real chance of a leakage in the building. They way felt is now designed,there should be a watertight seal around the nail but throughout the seasons with wear and tear this may fail resulting in a leakage.
• The most frequently ignored area on a timber cabin building is the felt or shingles on the roof structure. This is mainly because we can’t see it most of the time and it’s a lot more difficult to get up there and have a look,but this is just exactly what you should do and I would recommend at least once a year or if you notice a leakage. Because timber cabins are not built as high as the typical house and the felt and shingles aren’t fairly as tough and durable as a typical house tile they require a little more attention. They are subjected to more elements on a daily basis because they are lower,this can result in a number of things from falling debris from trees,or another example would be a kids’s toys getting thrown up there which would all result in damage to the felt/shingles. Not to mention lots of bird excrement can rot the felt if it is in an area where natural rain can not permeate it to create a natural run off and cleaning system (for example if your timber cabin sits under a plant).
Timberdise set up all of our timber cabins,we do this because we know you are investing a lot of cash into a timber cabin and you want it to be around for a long period of time. So the best way we can ensure this happens is to take care of the installation and make certain it is placed appropriately. We’ve been out to repair timber cabins in the past built by non-skilled people and if the building is not put together appropriately then number one it won’t be safe but in addition it could result in a failure in the building to be rainproof.
A prime example of this would be that the logs haven’t been constructed appropriately on the walls. This would then result in the timber cabin to differ from the design as it was intended to be. At this point when the roof structure was placed there might be voids between the roof structure and the wall. Openings could in addition appear on the walls of the timber cabins themselves and in some situations if the initial build of the timber cabin was so bad you would have no choice but to take down the timber cabin and reconstruct it.
This is why premium log cabins set up all of our timber cabins so you don’t have this to worry about. As you can imagine if there is a gap in the wall or a gap between the roof structure and the wall this would leave the cabin open and it would most definitely leakage which is what we want to avoid at all costs.
I in addition want to bring attention to the floor covering a second. Having your timber cabin placed on a proper ground base is a must. That could be a Timberdise ground base,concrete base or a paved area. As long as they’re flat,level and solid you should be ok. Be mindful of where you put the cabin,don’t put it anyplace that is at risk of flooding as just like the house that you live in. If the water level rises and there is no getaway for it then the timber cabin will flood,that is regardless of how thick and tight your logs are.
Lastly let’s talk about sealants around the windows and doors. Make certain after you have treated your cabin you fit the relevant sealants around the doors and the windows. The log cabins don’t come with these fitted as standard,this is so you can treat the cabin first and then apply the sealants afterwards. By not fitting the doors and windows with sealants then there’s a chance rain could permeate the inside of the cabin,which again is easily fixed by applying sealants.
Additionally,occasionally most especially during the winter months,condensation can happen inside a cabin. This is typical due to the log cabins not having any insulation fitted,it is not a leakage and can be fairly typical. We encourage at Timberdise to get a dehumidifier if you have electrical access in there and leave it operating during the colder months. This will help take water out of the air and further increase the lifespan of your cabin.
If you comply with all the above ideas you should have a leakage free cabin for the duration of its lifespan which can provide indefinite pleasure and relaxation.Always remember prevention is far better than the cure.
