Slate Roof Repairs and Re-Slating in Welwyn Garden City

Natural slate gives a roof a crisp, flat finish and keeps its colour for years, so it is worth looking after. TNR Roofing Services repairs slipped and cracked slates, deals with nail sickness and re-slates worn roofs on homes and commercial properties in Welwyn Garden City.

Slate roofs across AL7 and AL8 are surveyed from our base in Hemel Hempstead. If your home is listed or in a conservation area, Welwyn Hatfield Borough Council can confirm any rules on roofing materials, and we can reuse your existing slates where they are sound so the roof keeps its appearance.

How it works

What to Expect from Slate Roof Work in Welwyn Garden City

What happens from your first call to the finished work.

  1. Free Slate Roof Survey

    We check the slates, nails and battens, look for slipped pieces outside and staining in the loft, and tell you whether targeted repair or re-slating is the better route.

  2. Clear, No-Obligation Quote

    You get a written quote that sets out the slate to be used, how many existing slates we expect to reuse and any leadwork needed, so you can decide without pressure.

  3. Stripping, Sorting and Fixing

    With scaffolding up, slates come off by hand and sound ones are kept. New underlay and battens go on, then the slates are fixed course by course with hips, valleys and flashings finished as we rise.

  4. Final Review

    Once the ridge is secure and the old battens and broken slates are cleared away, we review the completed work with you and confirm everything has been done as agreed.

FAQs

Frequently Asked Questions

What are the signs a slate roof needs re-slating?

Slates slipping in several places, pieces of slate in the gutters, sagging or rotten battens, and staining in the loft. One or two slipped slates can be repaired, but widespread slipping usually means the nails have failed.

Can new slates be mixed with my original ones?

Yes. Where there is a shortfall after sorting the old slates, new ones are chosen to sit comfortably alongside the originals in size and thickness.

Does Welwyn Hatfield Borough Council need to approve re-slating?

Generally not for like-for-like re-slating. In AL7 and AL8, a listed building or a home in a conservation area may be treated differently, so ask the council before changing materials.

How long does re-slating take?

It depends on the size of the roof, the cutting at hips and valleys, and how many slates can be reused. Each slate is fixed by hand, so we give you an idea of timing with your quote.
