Product know-how

Klober help to put right some misconceptions about commonly used roofing products.

 

When you’re completing a roof there are a number of areas where misunderstandings over what works and what doesn’t can creep in. To help, the experts from Klober have highlighted some of the main points to be aware of when it comes to roofing accessories so you can finish the roof correctly.

DO I REALLY NEED TO USE AIR-OPEN UNDERLAYS?

The answer is yes unless you are adding supporting high level ventilation at or near the ridge. At the moment, Klober Permo® Air is one of only two air-open products on the market, so if you are told a product is air-open it’s always worth checking on the manufacturer’s website to see what the performance is.

ARE ALL LEAD-FREE FLASHINGS PRETTY MUCH THE SAME?

Definitely not, as they all vary in appearance and performance. There is a quick test to see how well one will perform – take two pieces of a product, such as Klober Wakaflex, peel off the backing of one and stick it to the facing of the other. You should find it almost impossible to break the bond and if that isn’t the case the product you have chosen is unlikely to last long.

IF I HAVE TO SEAL LAPS WHEN INSTALLING AN UNDERLAY WILL STANDARD DOUBLE-SIDED TAPE DO THE JOB?

Unfortunately it won’t. Tapes for this type of work need to be able to stick to rough and sometimes dusty surfaces, so you definitely need a product designed for the job. Alternatively, if you don’t want to waste time using a separate tape, an underlay such as Permo forte RS SK2 has edge tapes to guarantee a strong and durable airtight seal.

ARE THERE ANY DIFFERENCES WITH DRY VERGES?

Dry verges are made from different materials, for example polypropylene or PVC, and it’s these materials that often make a difference. Klober’s Uni-Click dry verge is now made from polypropylene, which means it’s lighter in weight – however it will last longer and is very durable. It’s also totally recyclable. This may not make much difference when fitting, however it is a factor that many self-builders are now taking notice of.

These are just some of the things to watch out for when using accessories to finish a roof.
So whether you need help with choosing the right roofing product for your job or want to keep up to date with the latest roofing developments, then do check with the supplier or manufacturer. Quality suppliers and manufacturers like Klober are more than likely able to offer support, provide technical advice and training. Not only will this increase your product know-how, it will also give you the confidence that the product is up to the job. That means you’ll get less call backs and gives your customer peace of mind.
