Are garden log cabins waterproof is a query we got asked all the time here at Timberdise Garden Buildings.
The very short simple answer to your query is an unquestionable yes!
Why would they not be?
Well,let’s take a look at some of the likely problems with a log cabin which would make the log cabin not waterproof and quite frankly not fit for purpose.The main thing to look at instantly is the roof structure,that’s where you would imagine the main problem would begin (this is not always the scenario but that’s where we will begin today). The main problem with the roof structure would be to have the felt or shingling to not be mounted correctly. This is quite easily done if this is something you have never done before and why it should always be tackled by a specialist particularly if you are putting in a lot of your hard earned cash on a log cabin.
• Make certain that the overlies are overlapping in the correct way. You should always begin felting at the bottom of the structure 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 structure. This will ensure there is a natural run off of the water,if you begin 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 operates off it will work under the felt and consequently lead to a leak. This is exactly the same when doing shingles,make certain you mount from bottom upwards.
• Make certain the overlies of the felt/shingles are quite generous. You don’t want them to be just barely overlapping because this could lead to rain to get between the felt sheets and this will lead to a leak
• Make certain 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 attach in the middle,possibly two rows but again this depends on the quality of the felt. Failure to put enough felt attach in there could result in the felt blowing off during a bad storm which would then leave your structure subjected to leakages.
• It is also important that when you reach the overhang of the structure with the felt you pin the felt to side of the roof structure but DO NOT tuck the felt under the overhang of the roof structure as this limits the natural run off of the water. This can lead to premature rotting of the structure and in some cases lead to the roof structure to leak around the top corners of the structure as water could build up.
• Make certain you use the correct size fixings. If the roofing boards on your structure 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 look cosmetically pleasing and would also be a real option of a leak in the structure. 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 neglected area on a log cabin structure is the felt or shingles on the roof structure. This is normally 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 recommend at least once a year or if you notice a leak. 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 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 lead to 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 instance 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 certain it is mounted correctly. We’ve been out to repair log cabins in the past built by non-skilled people and if the structure is not put together correctly then number one it won’t be safe but also it could lead to a failure in the structure to be waterproof.
A prime instance 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 mounted there might be gaps between the roof structure 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 Timberdise Garden Buildings mount all of our log cabins so you don’t have this to worry about. As you can imagine if there is a void in the wall or a void between the roof structure and the wall this would leave the cabin open and it would most definitely leak which is what we want to avoid at all costs.
I also want to bring attention to the floor a second. Having your log cabin mounted 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 escape 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 certain after you have treated your 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 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 cabin,which again is easily fixed by applying sealants.
Also,sometimes particularly during the winter months,condensation can happen inside a log cabin. This is normal due to the cabins not having any insulation fitted,it is not a leak and can be quite normal. We encourage at Timberdise to get a dehumidifier if you have electric access in there and leave it working during the colder months. This will help take dampness out of the air and further increase the life of your cabin.
If you observe all the above ideas you should have a leak free cabin for the duration of its life which can supply unlimited enjoyment and relaxation.Remember prevention is far better than the cure.
