Are garden timber cabins rainproof is a query we got asked all the time here at timberdise garden log cabins.
The concise simple answer to your query is an unqualified yes!
Why would they not be?
Well, let’s take a look at some of the conceivable complications with a log cabin which would make the timber cabin not rainproof and fairly honestly not fit for purpose.The main thing to appear at as soon as possible is the roof structure, that’s where you would envision the main issue would start (this is not always the situation but that’s where we will start today). The main issue with the roof structure would be to have the felt or roof shingles to not be mounted appropriately. This is fairly easily done if this is something you have never done before and why it should always be tackled by a specialist most especially if you are putting in a lot of your hard earned money on a log cabin.
• Make sure that the overlaps are overlapping in the correct way. You should always start felting at the bottom of the building and felt upwards. By doing this you ensure that the felt overlaps 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 run under the felt and consequently create a leak. This is just exactly the same when doing shingles, make sure you place from bottom upwards.
• Make sure the overlaps of the felt/shingles are fairly generous. You don’t want them to be just barely overlapping because this could create rainwater to get between the felt sheets and this will create a leak
• Make sure you use ample 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 attach in the middle,possibly two rows but again this depends on the quality of the felt. Failure to put enough felt attach in there could result in the felt blowing off during a bad storm which would then leave your building exposed to leaks.
• It is also important that when you reach the overhang of the building with the felt you nail 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 create early rotting of the building and in some cases create the roof structure to leak around the top corners of the building as water could build up.
• Make sure you use the correct size fixings. If the roof boards on your building are let’s say 10mm, you don’t want felt nails of 16mm. Doing this would create the felt nails to come completely through the roof structure. This would not appear cosmetically appealing and would also be a real possibility of a leak 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 leak.
• The most commonly overlooked area on a log cabin building is the felt or shingles on the roof structure. This is typically 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 strongly recommend at least once a year or if you notice a leak. Because timber cabins are not built as high as the typical house and the felt and shingles aren’t fairly as tough and resilient as a normal house tile they require a little more focus. They are exposed 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 instance would be a kids’s toys getting thrown up there which would all create harm to the felt/shingles. Not to mention lots of bird excrement can rot the felt if it is in an area where natural rainwater can not pass through it to create a natural run off and cleaning system (for instance if your timber cabin sits under a tree).
premium log cabins place all of our timber cabins, we do this because we know you are investing a lot of money into a log 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 sure it is mounted 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 also it could create a failure in the building to be rainproof.
A prime instance of this would be that the timbers haven’t been built appropriately on the walls. This would then create the timber cabin to differ from the design as it was intended to be. At this point when the roof structure was mounted there might be openings between the roof structure and the wall. Spaces could also 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 place all of our timber cabins so you don’t have this to worry about. As you can envision 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 leak which is what we want to avoid at all costs.
I also want to bring focus to the floor covering a second. Having your timber cabin mounted on a proper ground base is a must. That could be a Timberdise ground base,cement 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 any place that is at risk of flooding as just like the house that you live in. If the water level rises and there is no escape for it then the timber cabin will flood,that is regardless of how thick and tight your timbers are.
Lastly let’s talk about sealants around the windows and doors. Make sure after you have treated your cabin you fit the relevant sealants around the doors and the windows. The 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 rainwater could pass through the inside of the cabin, which again is easily fixed by applying sealants.
Also, sometimes most especially during the winter months, condensation can happen inside a log cabin. This is typical due to the cabins not having any insulation fitted, it is not a leak and can be fairly typical. We advise at Timberdise to get a dehumidifier if you have electrical access in there and leave it working during the cooler months. This will help take moisture content out of the air and further increase the life of your cabin.
If you comply with all the above ideas you should have a leak free cabin for the duration of its life which can offer limitless pleasure and relaxation. Remember prevention is much better than the cure.
