Bitumen is still the most widely used material on flat roofs in the Netherlands. Laid properly in two layers it lasts 25 to 30 years. The difference is in the details: the edges, the penetrations and the drainage.
We remove the old covering if it’s in poor shape, or lay a new layer over it if the base is still sound. Then an underlayer and a top layer, fully torched. All around we fit an aluminium roof trim or a zinc edge finish.
Torching on a roof is work for skilled hands. We always have extinguishers on the roof and check an hour afterwards that nothing is still smouldering.
With good maintenance, 25 to 30 years. Have it checked every two years and clear the leaves from the outlet, and you’ll reach that age.
The flat roof on our extension had leaked for years. Not any more, and neatly finished against the wall.
Old tiles off, insulation and new battens on, and a roof that will see you through the next thirty years.
New zinc gutters, lead around the chimney and flashings at dormers. That’s where most leaks start.
A thorough check of tiles, lead, gutters and attic, with a report and photos. Free if we do the renovation.
A leak after a storm or heavy rain? Within 24 hours we seal it temporarily, then a permanent repair follows.
Book an inspection. Within three working days you'll have a report with photos and a fixed price.
