Joint free continuous guttering pitfalls. As there are no satisfactory methods of joining this awful product, here is a typical bodge!

Derby Roofline refuse to install this outdated product

Downpipe silicon sealed into guttering

Note the extra downpipe installed into the aluminium gutter. As there is no suitable outlet-connector for continuous aluminium gutters the downpipe is simply placed into a hole and sealed with silicone.

As you can see below, the gutter is very flimsy so numerous brackets are required to fix it to the fascia board. This makes it extremely difficult to clean out,  and because this type of gutter needs to be installed absolutely level with no fall or slope the build up of debris is exacerbated. The photograph shows how debris can quickly build up to block the gutter.

Derby Roofline Do Not Over Clad! we only replace

Over clad bargeboard torn off with the wind

A section has been torn away in the wind and this could be a lethal flying object if it were to hit someone.

Why have other companies’ fascia boards and guttering changed colour?

Derby Roofline only use BBA Approved products

Non BBA approved fascia boards reacting in the sunlight

This is mainly due to inferior products. It is therefore essential that you see the BBA (British Board of Agrément) certificate before choosing a company to carry out your roofline refurbishment.

Salmon-pink fascias, as they are known in the trade.

In this example above we can see the discolouration, not only on the fascia boards but also on the brackets and guttering components.

Clearly there is no consistency in the manufacturing process here!

Just a few wrong ways to construct a box end gable corner

Amateur fitters trying there best!

Amateur fitters trying their best!

In these pictures, the companies which carried out the work on these homes, are clearly incompetent in constructing a boxed end.

The question has to be asked what else are they incompetent in doing?

The fitters have simply stuck pieces of fascia board together in an attempt to construct the corner detail.

Want a nice neat corner?

Compare the above examples with the way we do it here, and also note how we have re-pointed the gable end using new cement between the tiles and the fascia board.

The pitfalls of over-cladding

Derby Roofline always replace and do not cover

The dangers of cladding over



Here you can clearly see the damage caused to the original timber fascia board by over-cladding. The old fascia was completely saturated and the rot had penetrated into the timber joists behind. A full inspection of all surrounding joists was therefore required to ensure that no further hidden damage had been done. This is a clear warning as to the hazards of over-cladding and to the risk of employing inexperienced fitters.
