From the council houses of about 1950 to the bungalows at College Green and the private estates that came later, Sutton Benger added a lot of homes in a few decades. They went up quickly and to the building habits of their time, and most are now at the stage where the repairs any roof of that age needs have fallen due. Catching the early signs matters, because the same few faults tend to appear together.
Q2.1What makes ridges and verges fail on post-war roofs?
On a roof of this era the mortar under the ridge tiles cracks and lets go, and the verge pointing at the gable falls away in pieces. BS 5534:2014 changed the approach to ridge and hip tiles, which are now fixed mechanically as well as being bedded, so a repair now brings in mechanical fixings or a proprietary dry-fix ridge and verge. Our dry-fix ridge and verge page describes both.
Q2.2What happens to old felt and battens under the tiles?
Under the tiles, bitumen felt dries out and splits at the laps. A split does little harm while the tiles are sound, and a lot when one slips in a gale. If battens have rotted where water has run along them, a patch will not last, and stripping a section is the better answer.
Q2.3Could an older soffit contain asbestos?
For any building built or refurbished before 2000, the HSE says to presume asbestos is in it. Insulating board was fitted in some soffits, and by eye it looks much like modern board. If a soffit looks original, we pause and have it checked before cutting or drilling. Work on intact asbestos cement can be non-licensed, but insulating board is mostly licensed work, which is a reason to find out first.
