Are Garden Log Cabins Water Resistant?

Are garden timber cabins waterproofed is a question we got asked all the time here at Timberdise.


The concise simple answer to your question is a definite yes!


Why would they not be?


Well, let’s take a look at some of the likely issues with a timber cabin which would make the timber cabin not waterproofed and fairly honestly not fit for purpose.The main thing to seem at right away is the roof, that’s where you would visualize the main trouble would begin (this is not always the situation but that’s where we will begin today). The main trouble with the roof would be to have the felt or roof shingles to not be placed 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 most especially if you are putting in a lot of your hard earned money on a timber cabin.


• Make certain that the overlaps are overliing in the right way. You should always begin 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. This will ensure there is a natural run off of the water, if you begin felting at the top of the roof and you put the overlap from the bottom pieces over the top of the felt higher up when the rain works off it will work under the felt and therefor create a leakage. This is precisely the same when doing shingles, make certain you install from bottom upwards.


• Make certain the overlaps of the felt/shingles are fairly generous. You don’t want them to be just barely overliing because this could create rain to get between the felt sheets and this will create a leakage


• Make certain you use more than enough 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 nails in the middle,possibly two rows but again this depends on the quality of the felt. Failure to put enough felt nails 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 essential that when you reach the overhang of the building with the felt you pin the felt to side of the roof but DO NOT tuck the felt under the overhang of the roof 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 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 roofing system 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. This would not seem cosmetically appealing and would also 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 regularly neglected area on a timber cabin building is the felt or shingles on the roof. 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 precisely 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 normal house and the felt and shingles aren’t fairly as tough and sturdy 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 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 penetrate it to create a natural run off and cleaning system (for instance if your timber cabin sits under a plant).


garden log cabins install all of our timber cabins, we do this because we know you are investing a lot of money 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 takes place is to take care of the installation and make certain it is placed 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 create a failure in the building to be waterproofed.


A prime instance of this would be that the logs haven’t been assembled correctly 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 was placed there might be voids between the roof 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 rebuild it.


This is why garden log cabins install all of our timber cabins so you don’t have this to worry about. As you can visualize if there is an opening in the wall or an opening between the roof and the wall this would leave the cabin open and it would most definitely water leak which is what we want to avoid at all costs.


I also want to bring focus to the floor 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 anywhere 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 penetrate the inside of the cabin, which again is easily fixed by applying sealants.


In addition, in some cases most especially during the winter months, condensation can develop inside a log cabin. This is normal due to the log cabins not having any insulation fitted, it is not a leakage and can be fairly normal. We advise at Timberdise to get a dehumidifier if you have power access in there and leave it running during the chillier months. This will help take moisture out of the air and further increase the lifespan of your cabin.


If you follow all the above pointers you should have a leakage free cabin for the duration of its lifespan which can supply unlimited pleasure and relaxation. Remember prevention is better than the treatment.
