Three-Layer Torch-On Felt — Boldon

Modern SBS-modified bitumen felt is not the same product as 1970s pour-and-brush. On a Boldon garage a three-layer torch-on gives 20+ years and is genuinely repairable — patch weld a damaged area and it's as good as new. We're regularly on roofs close to the A19, through West Boldon and East Boldon.

Why old felt roofs get a bad name

Pre-1990s single-layer pour-and-brush felt on timber deck with no primer failed within 8–10 years and gave felt a terrible reputation. Modern three-layer SBS-modified torch-on is a completely different product — same category, different generation. Larger detached and semi-detached homes through East Boldon, with smaller terraces in Boldon Colliery. A lot of Boldon garages and single-storey extensions have marginal falls (1:60 or worse). Torch-on with proper primer copes with that; GRP struggles at flat.

What we don't do

Two-layer 'quick' felt roofs, or torching straight to a damp deck. Both fail early. If the deck's wet, we lift and re-board — it's usually £150–£300 of ply, and it's the difference between a 5-year and a 20-year roof.

Torch-on felt flat roofing in Boldon — FAQs

How long does a torch-on garage roof last?+

20+ years for a three-layer SBS-modified system installed correctly. We've walked on 25-year-old roofs of ours still bone-dry.

Can you overlay onto existing felt?+

Only if the existing is dry, sound and well-bonded. Nine out of ten times it isn't — we strip and re-lay. Overlaying a failed roof just adds weight to a problem.

Is torch-on cheaper than GRP?+

Slightly cheaper on materials, similar on labour, and marginally cheaper overall. Difference isn't big — pick on suitability, not price.

Do you cover Boldon?+

Yes — NE35 – NE36 in full, and neighbouring towns.
