Fascias, Soffits & Guttering In Hertfordshire

Affordable Windows offer everything you need for a complete, high performance roofline system, manufactured to the highest quality standards. From fascias, soffits and guttering to dry verge, over fascia ventilation and all the essential trims and accessories – We can install a roofline system that will really enhance your home.

A Quick Guide to Roofline Products

  • Fascia’s – The fascia is the roof board that protects the roof space from the elements. It preserves the timber rafters that hold your roof in place and provides a fixing point for guttering. The fascia looks a bit like a skirting board and is the part that ‘faces you’ as you look at your home.
  • Soffits – Soffits are the down facing boards that you would see if you stood with your back against your home and looked up. Soffits fill the gap between the fascia and the wall. Soffits can be fitted with air vents to provide ventilation to the roof space and loft.
  • Guttering and Downpipes –Guttering and downpipes safely remove rainwater from the roof. Guttering is usually attached to fascias.
  • Bargeboards – Bargeboards form the overhanging eaves that protect the gable end of a roof.

Why do Fascia’s and Soffits need replacing?

Fascia’s and soffits protect your home from the weather. They prevent damp getting into the brickwork and rot from affecting rafters, roof beams and joists.

Water damage is one of the most destructive forces that can affect any property. Once damp has found its way into a home it can be difficult to stop and expensive to treat. Rainwater that has penetrated timber fascias through holes or cracks in the paintwork will rot the wood and spread throughout the board.

Traditional timber fascia’s and soffits need regular maintenance. They should be painted, varnished or otherwise treated every four to five years to maintain water-resistance. We would recommend using UPVC products as a long term, low maintenance replacement product.

If you do nothing else to your home this year, check all timber fascia’s and soffits for signs of damage, cracks or rotting. The repair or replacement of damaged fascias, soffits, guttering or bargeboards will potentially save thousands of pounds and a great deal of distress.

Affordable Windows only install top quality UPVC fascia’s, soffits, guttering and associated roofline products. We take great pride in our products and our workmanship. Most of our work comes through recommendation from satisfied customers.

In April 2002 the building regulations were changed to require compliance for certain home improvements and building works including replacement of domestic windows and doors. To simplify the procedures Competent Person Schemes were set up by the government to provide the necessary certification, as an alternative to using a local Authority or private Approved Inspector.

Certass is a Competent Person Scheme for the glazing industry. All Certass registered members are vetted to ensure they are qualified to carry out the replacement of windows and doors in accordance with the current Building Regulations.
