Are Garden Timber Cabins Rainproof?

Are garden log cabins waterproof is a query we got asked all the time here at Timberdise Garden Buildings.


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


Why would they not be?


Well, let’s take a look at some of the possible complications with a log cabin which would make the log cabin not waterproof and fairly honestly not fit for purpose.The main thing to seem at quickly is the roof structure, that’s where you would visualize 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 shingling to not be installed 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 investing a lot of your hard earned cash on a log cabin.


• Make sure that the overlaps are overlapping 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 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 overlap from the bottom pieces over the top of the felt higher up when the rain runs off it will run underneath the felt and therefor lead to a leak. This is just exactly the same when doing shingles, make sure you mount 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 lead to rainwater to get between the felt sheets and this will lead to a leak


• Make sure you use 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 tack in the middle,possibly two rows but again this depends on the quality of the felt. Failure to put enough felt tack in there could result in the felt blowing off during a bad storm which would then leave your building subjected to leaks.


• It is additionally 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 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 cases lead to the roof structure to water 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 lead to the felt nails to come completely through the roof structure. This would not seem cosmetically pleasing and would additionally be a real chance 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 primarily 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 leak. Because log cabins are not built as high as the typical house and the felt and shingles aren’t fairly as tough and durable as a normal house tile they require a little more focus. 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 plants, or another good example 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 rainwater can not pass through it to create a natural run off and cleaning system (for good example if your log cabin sits under a tree).


premium log cabins mount all of our log 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 ensure this occurs is to take care of the installation and make sure it is installed correctly. We’ve been out to repair log 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 additionally it could lead to a failure in the building to be waterproof.


A prime good example of this would be that the timbers haven’t been built correctly on the walls. This would then lead to the log cabin to differ from the design as it was intended to be. At this point when the roof structure was installed there might be openings between the roof structure and the wall. Gaps could additionally appear on the walls of the log cabins themselves and in some situations if the initial build of the log cabin was so bad you would have no choice but to take down the log cabin and rebuild it.


This is why premium log cabins mount all of our log 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 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 additionally want to bring focus to the floor covering a second. Having your log cabin installed 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 at 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 log 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 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 rainwater could pass through the inside of the log cabin, which again is easily fixed by applying sealants.


Also, sometimes most especially during the winter months, condensation can develop inside a 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 power access in there and leave it operating during the chillier months. This will help take wetness out of the air and further increase the life-span of your log cabin.


If you adhere to all the above suggestions you should have a leak free log cabin for the duration of its life-span which can offer infinite enjoyment and relaxation. Keep in mind prevention is more desirable than the cure.
