Are garden log cabins waterproof is a question we got asked all the time here at View our products.


The concise simple answer to your question is an unqualified yes!


Why would they not be?


Well, let’s take a look at some of the plausible issues with a timber cabin which would make the log cabin not waterproof and quite frankly not fit for purpose.The main thing to seem at right away is the roof, that’s where you would imagine the main issue would commence (this is not always the situation but that’s where we will commence today). The main issue with the roof would be to have the felt or roof shingles to not be placed properly. This is quite 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 spending a lot of your hard earned money on a timber cabin.


• Make sure that the overlies are overlapping in the correct way. You should always commence felting at the bottom of the construction 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. This will ensure there is a natural run off of the water, if you commence felting at the top of the roof and you put the overlie from the bottom pieces over the top of the felt higher up when the rain runs off it will work under the felt and consequently result in a leakage. This is exactly the same when doing shingles, make sure you set up from bottom upwards.


• Make sure the overlies of the felt/shingles are quite generous. You don’t want them to be just barely overlapping because this could result in rain to get between the felt sheets and this will result in a leakage


• Make sure 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 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 construction exposed to water leaks.


• It is also vital that when you reach the overhang of the construction with the felt you attach 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 result in premature rotting of the construction and in some scenarios result in the roof to water leak around the top corners of the construction as water could build up.


• Make sure you use the correct size fixings. If the roofing boards on your construction 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. This would not seem cosmetically appealing and would also be a real possibility of a leakage in the construction. 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 commonly forgotten area on a timber cabin construction is the felt or shingles on the roof. 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 exactly what you should do and I would encourage at least once a year or if you notice a leakage. Because log cabins are not built as high as the normal house and the felt and shingles aren’t quite 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 good example would be a children’s toys getting thrown up there which would all result in harm 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 good example if your log cabin sits under a plant).


garden log cabins set up all of our log 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 sure it is placed properly. We’ve been out to repair log cabins in the past built by non-skilled people and if the construction is not put together properly then number one it won’t be safe but also it could result in a failure in the construction to be waterproof.


A prime good example of this would be that the timbers haven’t been built properly on the walls. This would then result in the log cabin to differ from the design as it was intended to be. At this point when the roof was placed there might be spaces between the roof and the wall. Openings could also 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 garden log cabins set up all of our log cabins so you don’t have this to worry about. As you can imagine if there is a space in the wall or a space between the roof 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 focus to the floor a second. Having your log cabin placed 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 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 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 log 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 permeate the inside of the log cabin, which again is easily fixed by applying sealants.


Also, at times most especially during the winter months, condensation can happen inside a cabin. This is normal due to the log cabins not having any insulation fitted, it is not a leakage and can be quite normal. We suggest at Timberdise to get a dehumidifier if you have electrical access in there and leave it working during the colder months. This will help take moisture out of the air and further increase the life of your log cabin.


If you comply with all the above strategies you should have a leakage free log cabin for the duration of its life which can provide endless fulfillment and relaxation. Remember prevention is better than the treatment.
