Re-Roofing Mountain Ash, One Terrace at a Time
Plenty of Mountain Ash roofs are still on their first covering after a hundred years or more - a credit to the original slaters, but every roof has a finish line. When yours reaches it, the honest fix is a strip and re-tile, not another round of patches.
The value in a re-roof is under the surface: a breathable membrane where there was often nothing at all, straight treated battens, timbers repaired while they are exposed, and ridges fixed mechanically instead of with mortar that the valley wind eats.
We work in sections and sheet down every night, so the house stays dry however the week turns out. It is the biggest job we do as a roofer in Mountain Ash – and the one we plan hardest.
What a Re-Roof Includes
Every layer, listed in your written specification before we lift a slate.
Strip & Disposal
The old covering off and away, with reusable slate saved and set aside.
Timber Checks & Repairs
Rafters and boards inspected in the open and repaired with your agreement.
Breathable Membrane
The modern barrier most old valley roofs never had - fitted as standard.
New Battens Throughout
Treated, graded battens - the fixing ground for the next fifty years.
Your Choice of Covering
Reused Welsh slate, new slate or interlocking tile - priced side by side.
Dry Ridge & Verge Systems
Clamped, screwed and weatherproof - no mortar to crack and drop.
Chimney & Leadwork
Flashings and stack work done while the scaffold earns its keep.
Insulation Top-Up
Loft insulation brought up to standard while the roof is open.

Repair Fatigue: Know the Signs
Any one of these alone is fixable. Several together is a roof telling you the truth.
A Roofer Out Every Winter
Annual repair bills are a re-roof on the instalment plan - without the new roof.
Slips Across the Whole Roof
When every course has a slipped slate, the fixings are finished roof-wide.
A Visible Sag
Dips in the ridge or roof plane mean the structure needs attention too.
Battens Letting Go
Slates coming away with the nail still in them - the batten has rotted around it.
Nothing Under the Slates
No felt or membrane means every slipped slate is an open tap into the loft.
Wind in the Loft
Draughts and daylight up there mean the covering no longer seals.

Frequently Asked Questions
Straight answers about re-roofing in Mountain Ash.
How long does a Mountain Ash terrace take to re-roof?
Usually one to two weeks – size, weather windows and whatever the open roof reveals in the timbers set the pace. You get a realistic programme with the quote, not a salesman’s one.
Will rain get in while the roof is off?
No – we only open what we can close, work in sections and sheet everything down at night. The house stays dry from first slate to last.
Can my original slate go back on?
If it is sound, absolutely – reused Welsh slate keeps the roof looking right for the street and trims the bill. We make up any shortfall with matched reclaimed slate.
What will you find when the roof comes off?
On roofs this age: usually some timber repairs, sometimes none, occasionally more. We price an approach with you up front and agree any extras before the work happens – never after.
Do I need permission to re-roof?
Like-for-like re-roofing rarely needs planning permission. Building regulations can apply, and we deal with the notifications where they do.
