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.
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.
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.
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.
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.
