Felt Roofing in Welwyn Garden City
Torch-On Felt Roofing in Welwyn Garden City
A garage or extension roof is easy to forget until water comes through. TNR Roofing Services repairs and replaces felt roofs in Welwyn Garden City, bonding a base sheet to the deck and a mineral cap sheet over it, so the finished roof is far tougher than the single sheet found on many older garages.
Our felt roofers serve homes and commercial properties in AL7 and AL8 from Hemel Hempstead. If your home is listed or in a conservation area, Welwyn Hatfield Borough Council can confirm any rules on changes to the roof, and our free survey sets out exactly what the work involves.

- Safe access to the roof, such as a tower or scaffold on a taller extension

How it works
What to Expect When We Re-Felt in Welwyn Garden City
What happens from your first call to the finished work.
Free Survey and Deck Check
We look for splits, blisters, lifted laps and standing water on the existing felt, and test the deck for soft or sagging areas, so the quote reflects what is really there.
Stripping and Priming
Old felt and loose chippings are removed, rotten boards are replaced, and the deck is cleaned and primed so the new layers bond firmly.
Torching on the Layers
The base sheet is torched onto the deck, then the mineral cap sheet is bonded over it with the laps staggered so no joint sits above another.
Edges, Upstands and Handover
Felt is dressed up walls and finished at the drip trims and outlets. We clear old felt and offcuts from site, then review the completed work with you and confirm everything has been done as agreed.
