Are garden timber cabins rainproof is a query we got asked all the time here at timberdise garden log cabins.
The brief simple answer to your query is an unquestionable yes!
Why would they not be?
Well, let’s take a look at some of the conceivable issues with a log cabin which would make the timber cabin not rainproof and fairly honestly not fit for purpose.The main thing to seem at as soon as possible is the roof structure, that’s where you would imagine the main problem would commence (this is not always the situation but that’s where we will commence today). The main problem with the roof structure would be to have the felt or shingling to not be mounted correctly. This is fairly easily done if this is something you have never done before and why it should always be carried out by a specialist especially if you are spending a lot of your hard earned cash on a log cabin.
• Make certain that the overlies are overliing in the proper way. You should always commence felting at the bottom of the building and felt upwards. By doing this you guarantee that the felt overlies on top of the piece of felt that is further down the roof structure. This will guarantee there is a natural run off of the water, if you commence 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 underneath the felt and consequently lead to a water leak. This is precisely the same when doing shingles, make certain you install 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 lead to rain to get between the felt sheets and this will lead to a water leak
• Make certain 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 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 exposed to water leaks.
• It is also important 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 underneath the overhang of the roof structure as this limits the natural run off of the water. This can lead to early rotting of the building and in some situations lead to the roof structure to water leak around the top corners of the building as water could build up.
• Make certain you use the right 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 lead to the felt nails to come completely through the roof structure. This would not seem cosmetically appealing and would also be a real option of a water 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 water leak.
• The most frequently forgotten area on a log cabin building is the felt or shingles on the roof structure. This is generally 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 precisely what you should do and I would suggest at least once a year or if you notice a water leak. Because timber cabins are not built as high as the normal house and the felt and shingles aren’t fairly as tough and resilient as a typical house tile they require a little more attention. 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 children’s toys getting thrown up there which would all lead to 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 pass through it to create a natural run off and cleaning system (for instance if your timber cabin sits under a plant).
Timberdise install all of our timber cabins, we do this because we know you are investing a lot of cash into a log cabin and you want it to be around for a long period of time. So the best way we can guarantee this takes place is to take care of the installation and make certain it is mounted correctly. We’ve been out to repair timber cabins in the past built by non-skilled people and if the building is not put together correctly then number one it won’t be safe but also it could lead to a failure in the building to be rainproof.
A prime instance of this would be that the logs haven’t been built correctly on the walls. This would then lead to 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 gaps 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 Timberdise Garden Buildings install 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 log cabin open and it would most definitely water leak which is what we want to avoid at all costs.
I also want to bring attention to the flooring 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 log 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 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 log 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 log cabin first and then apply the sealants afterwards. By not fitting the doors and windows with sealants then there’s a chance rain could pass through the inside of the log cabin, which again is easily fixed by applying sealants.
Also, at times especially during the winter months, condensation can materialize inside a cabin. This is normal due to the cabins not having any insulation fitted, it is not a water leak and can be fairly normal. We recommend at Timberdise to get a dehumidifier if you have electric access in there and leave it working during the chillier months. This will help take water out of the air and further increase the lifespan of your log cabin.
If you comply with all the above guidelines you should have a water leak free log cabin for the duration of its lifespan which can offer infinite fulfillment and relaxation. Don’t forget prevention is better than the treatment.
