When does a garage roof in Magherafelt need replacing?
Many garages in Magherafelt still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.
Around Magherafelt, flat roofs are common on bungalows with flat-roofed side extensions and dormers and on shops with flat-roofed rear stores below flats. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.
How much does a new garage roof cost in Magherafelt?
At Northern Ireland guide rates, a typical 18 m² garage roof in EPDM comes to £1,400–£2,450 including VAT. The fixed price comes after a free survey for new and replacement roofs.

What if my garage roof is asbestos cement or old felt?
If your garage has corrugated cement sheets, especially on a pre-2000 building, assume they could contain asbestos until a test says otherwise. We do not remove asbestos; any suspected material is tested and, if confirmed, removed by a licensed specialist before our work starts.
Once the old sheets have gone, the garage usually needs new timber joists or purlins and a deck before a membrane can go on. Old felt garages are more straightforward: the felt is stripped and the deck assessed in the usual way.
Lock-up blocks and rows of garages bring their own issues. A shared roof often has several owners, so we can quote per bay, or for the whole run where everyone agrees, which keeps the edges and joins between garages consistent. Attached garages need careful upstands and flashings where the roof meets the house wall, while detached ones are about edges, gutters and falls.
Not sure whether your roof needs replacing? Our guide to repair or replace sets out the signs.

Building control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.
