The service

What Roof Windows (Velux) Involves

Roof windows such as Velux sit in the slope of the roof and let in far more light than a vertical window of the same size. They're popular in loft conversions, landings, bathrooms and extensions.

You might need this service if you want to add light to a loft or room, if an old roof window is leaking, misted, draughty or hard to open, or if you're re-roofing and want to add windows at the same time.

The window itself is only half the job. It has to be framed into the rafters correctly and sealed with the right flashing kit and membrane collar, or it will leak around the edges.

If it's left

What Happens If You
Wait Another Winter

Leaks around the frame

A poorly flashed roof window lets water run into the reveal and down the wall inside.

Condensation and draughts

Old or failed units let heat out and cause condensation that drips onto sills and floors.

Rotting timbers

Persistent leaks around the opening damage rafters and trimmers.

Dark rooms

Without enough daylight, top-floor rooms and lofts are underused and feel cramped.

Common Mistakes
Homeowners Make

  • Fitting a window without the correct flashing kit for the roof covering
  • Cutting rafters without trimming the opening properly
  • Leaving out the underfelt or membrane collar

In detail

Roof Windows (Velux) Across
Leicester & Blaby

New installations

We trim the opening, fit the frame, install the correct flashing for tiles or slates and seal the membrane so the window is watertight.

Replacements

Old units can often be replaced in the same opening. If the size has changed, we adjust the opening and make good the tiles.

Leak repairs

If an existing roof window leaks, we find out whether it's the flashing, the seal or the surrounding roof and fix the cause.

With a re-roof

Adding windows during a re-roof keeps costs and disruption down because the roof is already open.

Homes and Rental Properties

Most of our roof windows (velux) work is for homeowners, from terraces and semis to bungalows and detached houses. We also work for landlords who need a reliable fix and a clear record of what was done. Every job gets the same approach: a proper look at the roof, photos of what we find, and a fixed price before anything starts. If you're a landlord or a prospective buyer rather than the owner occupier, a £75 fee applies to the inspection; for homeowners it's free.

How to Choose a Roofer

Ask for a written, fixed price rather than a day rate, so the cost can't creep up once the scaffold is up. Ask to see photos of the problem before agreeing to anything. Check the guarantee, and get it in writing. Ask who will actually be on your roof. With us, it's Bobby Button and a team of four from start to finish, and the guarantee for your job is confirmed with your quote.

What to Expect on the Day

We turn up when we say we will and talk you through the plan before work starts. The roof is kept weathertight at the end of every working day, and we clear away old materials and debris as we go. When the job is finished we check it over, show you the completed work and tidy the site properly, so the only thing you notice is a roof that works.

Your Guarantee, Explained

Guarantee length depends on the type of work. A new roof is guaranteed for 25 years as standard. Work involving breathable membrane, including many leak repairs, is usually guaranteed for 10 years and in some cases 5. Cement work such as mortar and pointing is guaranteed for 5 years. Whatever your roof windows (velux) involves, the exact guarantee is written into your quote, so you know where you stand before you say yes.

"Robert and his team done a fantastic job. I had a leak on my roof which they fixed very promptly, I also had them re-point my ridge tiles on my roof and it looks great. Very happy with the service, would definitely recommend."
