Are Garden Timber Cabins Watertight?

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

The brief simple answer to your query is a resounding yes!

Why would they not be?

Well,let’s take a look at some of the potential complications with a log cabin which would make the timber cabin not waterproof and quite frankly not fit for purpose.The main thing to seem at immediately is the roof structure,that’s where you would visualize the main complication would start (this is not always the situation but that’s where we will start today). The main complication with the roof structure would be to have the felt or roof shingles to not be set up successfully. This is quite easily done if this is something you have never done before and why it should always be undertaken by a qualified professional particularly if you are spending a lot of your hard earned cash 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 runs off it will work beneath the felt and consequently trigger a leak. This is precisely the same when doing shingles,make sure you place from bottom upwards.

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

• Make sure you use sufficient 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 subjected to water leaks.

• It is in addition crucial that when you reach the overhang of the building with the felt you tack the felt to side of the roof structure but DO NOT tuck the felt beneath the overhang of the roof structure as this limits the natural run off of the water. This can trigger early rotting of the building and in some cases trigger 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 roofing system boards on your building are let’s say 10mm,you don’t want felt nails of 16mm. Doing this would trigger the felt nails to come completely through the roof structure. This would not seem cosmetically pleasing and would in addition be a real opportunity 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 typically neglected area on a log cabin building is the felt or shingles on the roof structure. 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 precisely what you should do and I would highly recommend at least once a year or if you notice a leak. Because timber 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 attention. 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 instance would be a kids’s toys getting thrown up there which would all trigger damage to the felt/shingles. Not to mention lots of bird droppings 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 tree).

timberdise garden log cabins place 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 ensure this occurs is to take care of the installation and make sure it is set up successfully. We’ve been out to repair timber cabins in the past built by non-skilled people and if the building is not put together successfully then number one it won’t be safe but in addition it could trigger a failure in the building to be waterproof.

A prime instance of this would be that the logs haven’t been constructed successfully on the walls. This would then trigger the timber cabin to differ from the design as it was intended to be. At this point when the roof structure was set up there might be openings between the roof structure and the wall. Gaps could in addition 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 log cabins place all of our timber cabins so you don’t have this to worry about. As you can visualize if there is a space in the wall or a space 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 in addition want to bring attention to the floor surface a second. Having your timber cabin set up 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 escape 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 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 penetrate the inside of the log cabin,which again is easily fixed by applying sealants.

Also,in some cases particularly during the winter months,condensation can develop inside a cabin. This is normal due to the log cabins not having any insulation fitted,it is not a leak and can be quite normal. We recommend at Timberdise to get a dehumidifier if you have electric access in there and leave it operating during the cooler months. This will help take dampness out of the air and further increase the life of your log cabin.

If you stick to all the above recommendations you should have a leak free log cabin for the duration of its life which can provide endless pleasure and relaxation.Remember prevention is better than the cure.
