Flat Roofing Melksham

Deck Inspection First

Before any GRP installation we probe the deck for deflection or moisture damage. A spongy or wet deck requires repair before GRP work begins — GRP over a compromised deck cracks at flex points within 2 to 5 years. We photograph deck condition and quote deck repair separately if needed, before starting any membrane work.

Same-Day Installation

A standard garage or extension flat roof is laminated in GRP fibreglass in a single day. Deck prepared, GRP laminated, gelcoat applied, edge detail and outlet connected. Property fully accessible by the following morning after overnight cure. 25-year manufacturer warranty certificate issued at handover.

Drainage and Falls

Correct drainage falls are checked before installation begins. Minimum 1:80 fall required for GRP to drain correctly. Where the existing deck has inadequate fall, we quote for fall correction before work starts. A correctly drained GRP roof performs for 30 to 40 years. An under-drained one accumulates standing water and degrades faster.

Melksham's Roofing Context

Melksham's Bath Road and King Street Victorian terraces have Welsh slate now 110 to 140 years old. The Forest estate and Queensway post-war housing has concrete tile ridge mortar in various stages of carbonation. The Avon valley floor location creates above-average humidity across all Melksham housing — moss growth on north-facing slopes is above average, and soaker corrosion on period properties is faster than at drier locations. We carry matching Welsh slate and concrete tile profiles on all SN12 vehicles.

Melksham's flat roof stock — principally on rear extensions across the Forest estate and Queensway post-war housing — was largely installed in felt in the 1970s to 1990s and is now at or past end of design life. The Avon valley humidity at Melksham's position accelerates felt lap joint degradation faster than at drier locations. GRP replacement of these systems removes the lap joints entirely. The majority of Melksham flat roof calls involve systems that have been patched at least once and are now at the systematic replacement threshold — we give an honest assessment of patch viability versus replacement on every Melksham flat roof survey.

Melksham's Avon valley floor position at approximately 50 metres gives it sustained above-average humidity. The Forest estate flat roof stock — principally on rear extensions from the 1970s to 1990s — is now at or past end of design life, with the valley humidity having accelerated felt lap joint degradation on many of these properties. GRP replacement eliminates the lap joints entirely. Most Melksham flat roof installations are single-day jobs. Deck inspection included — the valley humidity has compromised some Forest estate decks beneath the failing felt.

Survey and Assessment

Free surveys in Melksham are typically scheduled within 3 to 5 working days. The survey covers the full roof from physical access, loft timber inspection, all lead and chimney condition. For Bath Road and King Street Victorian terraces, the survey includes soaker condition assessment — the Avon valley floor humidity accelerates soaker corrosion on Welsh slate properties more than at drier locations, and soaker condition is a key variable in the repair versus re-slating recommendation.

Costs and Pricing

Roof repair costs in Melksham range from £100 to £200 for single tile or slate, £250 to £500 for ridge re-bedding on Forest estate post-war housing, and £200 to £600 for lead valley work on Victorian terraces. For properties where the Avon valley humidity has accelerated deterioration beyond the repair threshold, we give an honest re-roofing assessment as part of the survey. All costs in writing before work starts. No call-out fee.

Guarantee and Handover

All Melksham roofing work carries a written 10-year workmanship guarantee. GRP flat roofing carries a 25-year manufacturer warranty. Documentation provided for conservation file properties at no additional charge.
