Are garden log cabins watertight is a query we got asked all the time here at View our products.
The short simple answer to your question is a resounding yes!
Why would they not be?
Well, let’s take a look at some of the potential issues with a timber cabin which would make the log cabin not watertight and fairly frankly not fit for purpose.The main thing to seem at immediately is the roof structure, that’s where you would imagine the main problem would begin (this is not always the situation 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 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 qualified professional particularly if you are spending a lot of your hard earned money on a timber cabin.
• Make certain that the overlaps are overliing in the correct 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 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 works off it will run underneath the felt and therefor result in a leakage. This is precisely the same when doing shingles, make certain you place 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 result in rainwater to get between the felt sheets and this will result in a leakage
• 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 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 leaks.
• It is also 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 result in early rotting of the building and in some situations result in the roof structure to leak around the top corners of the building as water could build up.
• Make certain you use the right 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 result in the felt nails to come completely through the roof structure. This would not seem cosmetically appealing and would also be a real option 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 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 precisely what you should do and I would strongly recommend 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 fairly as tough and sturdy as a typical 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 example would be a kids’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 rainwater can not penetrate it to create a natural run off and cleaning system (for example if your log cabin sits under a tree).
premium log cabins place 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 certain it is placed 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 also it could result in a failure in the building to be watertight.
A prime example of this would be that the logs haven’t been built correctly 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 structure was placed there might be voids between the roof structure and the wall. Gaps 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 reconstruct it.
This is why garden log cabins place 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 log cabin open and it would most definitely leak which is what we want to avoid at all costs.
I also want to bring focus to the floor covering a second. Having your log 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 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 getaway for it then the log 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 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 penetrate the inside of the log cabin, which again is easily fixed by applying sealants.
Also, at times particularly during the winter months, condensation can occur inside a cabin. This is normal due to the cabins not having any insulation fitted, it is not a leakage and can be fairly normal. We suggest at Timberdise to get a dehumidifier if you have power access in there and leave it running during the cooler months. This will help take water out of the air and further increase the life of your log cabin.
If you follow all the above suggestions you should have a leakage free log cabin for the duration of its life which can provide limitless pleasure and relaxation. Bear in mind prevention is much better than the cure.
