Binscombe — Local Housing and Roofing Conditions
The estate was built in a single phase during the early 1950s, meaning virtually every roof is the same age and the same specification — Redland or Marley concrete interlocking tiles on softwood battens with bituminous felt. After nearly 70 years, these materials have reached and exceeded their design life. The concrete tiles show widespread surface erosion, loss of water repellency, and frost cracking. The battens beneath are often soft with moisture absorption even where the tiles appear sound from outside.
Weather and Environmental Factors in Binscombe
The heavy Atherfield Clay subsoil retains moisture around foundations, creating ground-level humidity that rises and affects the lower portions of the roof structure. Fascia and soffit rot is more common on Binscombe properties than anywhere else in Godalming, directly linked to this clay-related damp. Properties on the western edge of the estate face prevailing weather with no shelter, and these show 20-30% more tile damage than those in the estate interior.
Our Flat Roofing Inspection Process
Flat roof surveys reveal what pitched roof surveys cannot — the condition of the deck beneath the waterproof membrane. We cut a test section (approximately 300mm square) of the existing covering to inspect the timber deck directly, checking for rot, delamination and structural integrity. This test cut is essential because a deck that looks sound from above can be severely compromised beneath a membrane that appears intact. If the deck is sound, we repair the test section as part of the new installation. If it reveals problems, you know before committing to the full project rather than discovering rotten timbers after the old roof has been stripped.
Materials We Use for Flat Roofing in Binscombe
We install two flat roofing systems: GRP fibreglass for areas under 30 square metres (garages, porches, small extensions) and EPDM rubber for larger areas. Both are single-ply systems that eliminate the joints and laps where traditional felt roofs fail. Our GRP specification uses Scott Bader Crystic resin with minimum 450gsm chopped strand mat, built up in controlled layers with a UV-resistant topcoat. Our EPDM specification uses Firestone RubberCover or ClassicBond membrane bonded to the deck with full contact adhesive and mechanically fixed perimeter details. Both systems carry manufacturer warranties of 20-30 years in addition to our 10-year workmanship guarantee.
Local Tip for Binscombe Homeowners
If your Binscombe home has not had a professional roof survey in the past five years, we strongly recommend booking one. Many properties on this estate are one bad winter away from needing emergency work that could have been prevented with planned maintenance. Our survey is free, honest, and takes 30-45 minutes.
