Keeping Mountain Ash Roofs Out of Trouble
The roofs of Mountain Ash spend every winter being tested - rain off the mountain, wind up the valley, frost in between. Most of the expensive damage we repair did not start big: it started as a blocked outlet or one loose slate that nobody saw for two years.
Maintenance is simply getting eyes on the roof before the weather finds the weak spot. Gutters cleared, moss dealt with, small repairs done on the spot - and a photographic record of what is up there, so nothing is a surprise.
If the roof is healthy, our report says so – we do not invent work. That honesty is why homes across the valley have the same Mountain Ash roofer back year after year.

Frequently Asked Questions
Straight answers about roof maintenance in Mountain Ash.
How often does a valley roof need checking?
Yearly – ideally in early autumn so it goes into the storm season sound – plus a quick look after any really wild night. Mountain Ash roofs face more weather than the Met Office average, and it shows.
What exactly do I get from a visit?
A full inspection with photos, cleared gutters and outlets, minor repairs done on the spot, and a short written report on anything worth watching – including “all fine” when it is.
Can you get moss off without damaging the slates?
Yes – by hand and with the right treatments. We never jet-wash slate: it strips the surface and drives water where it should not go, shortening the roof’s life to make it look briefly cleaner.
Do you look after rental properties?
Yes – landlords across the Cynon Valley use us for scheduled checks with per-property reports, which keeps small faults from ever becoming tenant phone calls.
What does a maintenance visit cost?
A small fixed cost that depends mainly on roof size and access – a fraction of what a winter of hidden leaking costs. Quotes are free.
