Flat roofs in Aldershot face specific challenges from Aldershot sits on a low sandy plain with woodland to the south. Properties backing onto Aldershot Park and the military land face high leaf fall volume causing valley and gutter blockages every autumn.. Getting the drainage specification right for local conditions is as important as the membrane choice.

Aldershot's Victorian garrison terraces present some of the most specific roofing requirements in the area. Original Welsh slate on properties along Wellington Avenue and the surrounding streets requires matching natural slate for repairs — and lime mortar for all pointing work. Using cement mortar on these properties causes spalling brickwork within 10 years.
Flat roofing in Aldershot requires correct drainage specification above all else. The minimum recommended fall for a flat roof is 1:80 — roughly 12mm per metre. Many failed flat roofs we inspect in Aldershot were installed with inadequate falls, causing ponding that saturates the membrane and backing. We re-profile decks where required as part of any flat roof installation.
The diversity of housing eras in Aldershot — from 1870s garrison terraces to 1970s council stock in South Aldershot — means local knowledge is particularly important. What's right for one property type is wrong for another half a mile away.
Properties backing onto woodland near Aldershot Park face above-average leaf fall volume every autumn. Valley and gutter clearance is critical here — blocked valleys are the primary cause of roof leaks we attend in the Aldershot area each November and December.
"New GRP roof on the extension. Perfectly level, good drainage, no issues in 18 months including a very wet winter. Far better than the old felt."
"Garage flat roof replaced in EPDM. Half a day's work, very tidy. Explained the drainage issue with the old roof clearly and sorted it properly."
"Had three quotes for the flat roof on the back extension. Went with these because they identified a drainage problem the others missed. Right call."
GRP fibreglass is our standard recommendation for most Aldershot properties — fully seamless, longest lifespan and maintenance-free. EPDM is preferable for larger areas or unusual shapes. Felt is a cost-effective option where budget is the primary constraint.
GRP fibreglass 25–30 years. EPDM rubber 20–25 years. Quality torch-on felt 15–20 years. Traditional built-up felt 10–15 years. Lifespan depends heavily on correct installation — particularly adequate drainage falls.
Flat roof replacements like-for-like don't require planning permission. If you're adding a new flat roof where there wasn't one before, or raising the height, permitted development rules apply and we'll advise at survey stage.
The most common causes in Aldershot are ponding water from inadequate falls, failed seams or edges on older felt roofs, and cracked or blistered surfaces. We identify the exact cause before recommending repair or replacement.
