Why Windsor sagging roof diagnosis & repair is its own kind of job
Windsor sits low on the Thames flood plain — ground humidity and mist keep north-facing slate damp through winter, and we specify slate hooks in preference to nails on any full re-lay to avoid future nail-sickness. We work across SL4 and the surrounding villages. Most weeks the same van is in maidenhead, slough and datchet on adjacent jobs.
What's driving sagging roof diagnosis & repair on SL4 roofs
SL4 Crown Estate cottages use a specific handmade peg-tile from a Sussex works — we hold contact details and lead time (typically 8 weeks) at quote stage so programme dates hold. On a typical Windsor street near Windsor Castle we'd expect the same handful of failure points to show up — slipped ridges, dry-perished mortar, lead splits at the chimney apron. We know what to look for before the scaffold even goes up.

Will my insurer accept your Windsor report?+
Yes — we provide photo-documented reports with the cause, scope and quoted repair. We've done this for most major UK insurers on jobs around Windsor Castle.
Can you find the leak if it's not obvious?+

Autumn and early spring — after the first A308-corridor storms expose weak spots. Book SL4 surveys 2-4 weeks ahead during those windows.
Will the repair last on a Windsor property?+
We spec to the local stock — like-for-like materials, proper mechanical fixings, code 4 or 5 lead at flashings — and back it with a written workmanship guarantee.
Do you cover Windsor?+
Yes — Windsor is one of our regular areas. We work across SL4 weekly from our High Wycombe base (11.9 miles via M4 Junction 6). Building control notifications go through Royal Borough of Windsor and Maidenhead where required.
