Are garden timber cabins waterproof is a question we got asked all the time here at Timberdise garden Products
The short simple answer to your question is an unquestionable 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 timber cabin not waterproof and quite honestly not fit for purpose. The main thing to appear at as soon as possible is the roof, that’s where you would imagine the main trouble would commence (this is not always the situation but that’s where we will commence today). The main trouble with the roof would be to have the felt or shingling to not be installed successfully. 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 overlaps are overlapping in the proper way. You should always commence felting at the bottom of the construction 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. 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 operates off it will operate under the felt and therefor bring about a water leak. This is precisely the same when doing shingles, make sure you install 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 bring about rainwater to get between the felt sheets and this will bring about a water 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 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 subjected to leakages.
• It is additionally essential that when you reach the overhang of the construction with the felt you nail 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 bring about premature rotting of the construction and in some situations bring about the roof to water leak around the top corners of the construction as water could build up.
• Make sure you use the right 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 bring about the felt nails to come completely through the roof. This would not appear cosmetically appealing and would additionally be a real chance of a water leak 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 water leak.
• The most typically overlooked area on a timber cabin construction is the felt or shingles on the roof. This is generally 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 encourage at least once a year or if you notice a water leak. Because timber cabins are not built as high as the typical 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 children’s toys getting thrown up there which would all bring about 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 pass through it to create a natural run off and cleaning system (for instance if your timber cabin sits under a plant).
www.timberdisegardenbuildings.co.uk install all of our timber 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 occurs is to take care of the installation and make sure it is installed successfully. We’ve been out to repair timber cabins in the past built by non-skilled people and if the construction is not put together successfully then number one it won’t be safe but additionally it could bring about a failure in the construction to be waterproof.
A prime instance of this would be that the timbers haven’t been assembled successfully on the walls. This would then bring about the timber cabin to differ from the design as it was intended to be. At this point when the roof was installed there might be spaces between the roof and the wall. Gaps could additionally 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 we install all of our timber cabins so you don’t have this to worry about. As you can imagine if there is a gap in the wall or a gap between the roof and the wall this would leave the cabin open and it would most definitely water leak which is what we want to avoid at all costs.
I additionally want to bring attention to the floor a second. Having your timber 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 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 timber 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 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 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 cabin, which again is easily fixed by applying sealants.
In addition, in some cases most especially during the winter months, condensation can materialize inside a cabin. This is typical due to the log cabins not having any insulation fitted, it is not a water leak and can be quite typical. We advise at Timberdise to get a dehumidifier if you have power access in there and leave it working during the cooler months. This will help take water out of the air and further increase the lifespan of your cabin.
If you observe all the above recommendations you should have a water leak free cabin for the duration of its lifespan which can provide infinite pleasure and relaxation. Always remember prevention is much better than the cure.
