Why it is best to Fully Replace Existing Fascia and Soffit Boards rather than Capping over them


The replacement plastic alternatives for the roofline are UPVC fascia and soffit boards. With a great pace, they are becoming the norm in roof edge construction and renovation.

They are designed and manufactured so that they do rot, and in most cases, they last for a lifetime. A usual replacement project will include organizing an arena tower or work platform, removing the first course of roof tiles, and then taking off the existing timber roofline before the installation of the new plastic boards can start. The operation is concluded by putting a new gutter system, and strong eaves felt tray before the tiles are laid back onto the roof. Furthermore, concerning all the building work, techniques exist that can reduce the amount of work ramified – saving on the homeowner money. Hence these options are preferred by the homeowner to go economical. One of the known procedures is Over Capping.

Replace Existing Fascia

Capping is commonly also known as over-cladding. It is a method of roof edge construction where the initial timber boards are left in position, and the upgraded UPVC plastic system is conveniently fixed upon the old structure. This method is comparatively more economical as compared to the removal of the old timber. This may seem like a tempting alternative for the homeowner, even though there is a catch in My Update System.

There is a probability that the existing boards will be replaced because they are on the verge of life, and painting is no longer working. Fixation of a thin capping board to an unsound substructure is like an uncalled blunder. This will lead to the spreading of any existing rot that would spread quickly due to poor ventilation.

Many other obstacles are related to the over-clad method, such as how the completed work will look if you live in a terraced or semi-detached property. The overhang of the roof tiles at eaves level is shrunk by the capping method. This, in turn, would result in rainwater running behind the guttering. This type of felt is extensively utilized to cover over into the guttering. It can avoid water from running behind the guttering, and should the property suffer a broken tile; any water will be guided down the roof and into the gutter, not onto the ceiling.

UPVC products are designed in such a way that they could last for many years. Almost all manufacturers and installers provide a ten-year guarantee on the materials. Furthermore, we have yet to find a company that will offer a warranty on the timber structure these UPVC boards are fixed to.
