Streatham's terraces and the roofs on top of them

Streatham grew up along the A23 in the late Victorian boom, and the roofs from those years define it. Streatham Hill, Telford Park and the roads round Streatham Common are packed with large terraced and semi-detached houses: three storeys, natural slate, parapet walls at the front and a valley gutter running down the middle of the roof behind them. That hidden valley collects leaves and silt, and when it blocks or its lead splits, water comes straight through the top-floor ceiling.

Nearer the High Road there are mansion blocks and shops with flats above, and Streatham Vale to the south is a 1930s estate of hipped semis and short terraces. Chimney stacks here are tall and carry several pots, so the lead flashing round them matters. Apex come up the A23 from Croydon, and Patrick goes up to the valley himself to photograph what has failed. You see the gutter, the lead and the slates before a price is agreed.

Streatham roof problems, from gutter to ridge

Victorian London roofs hide their weak spots behind the parapet.

Blocked central valley gutters

The valley between two slopes is out of sight from the street. Leaves and grit build up, water backs up under the slates and pours into the loft. Apex clear it and reline worn sections in code 4 lead.

Split parapet flashing

Where the slate meets the front parapet, a lead flashing keeps the rain out. Old lead cracks and the mortar joint above it opens up. Apex dress in new lead and repoint the chase it sits in.

Slipped and cracked slates

Iron nails in Victorian slate rust through after a century. Slates then slip, crack or drop into the gutter. Apex refix single slates, or strip a slope and re-slate it on new battens and membrane.

Multi-pot chimney stacks

Streatham stacks stand tall above the ridge and take the weather on every face. Frost breaks the pointing and the lead lifts. "Very satisfied with results on chimney pointing and lead seal," wrote one Google reviewer.

Roofing questions from Streatham

Why does my Streatham loft leak after heavy rain?

A leak that only shows after heavy rain on a Victorian Streatham house is most often the central valley gutter overflowing. Leaves and silt build up behind the parapet, the water rises above the lead and runs under the slates. Split lead in the valley or at the parapet does the same. Patrick goes up, finds which it is and sends you photos, so you know the cause before you agree a fix.

Can Apex reach a valley gutter behind a parapet?

Yes. A valley gutter behind a front parapet is reached from above, over the rear slope or from a scaffold tower, depending on the house. Patrick works out safe access when he visits and builds it into the fixed price. Clearing, resealing or relining the valley in code 4 lead is everyday work for Apex on roofs like these.

Should I replace the slate on a Streatham terrace with slate-effect tiles?

Natural slate is the better fit for most Streatham terraces, and the safe choice in a conservation area such as Telford Park, where the council expects the roof to keep its character. Slate-effect tiles are lighter and cheaper to buy, and Apex fit both. Patrick explains the difference on your own roof, and the free quote prices each option so you can pick.

Does Apex work on Streatham's 1930s semis as well as the Victorian terraces?

Yes. Streatham Vale and the streets towards Norbury are full of 1930s hipped semis, and Apex repair and re-roof those as readily as the big slate roofs further north. On the semis, the faults Patrick checks for first are loose hip tiles, leaking bay roofs and tired concrete tiles. He photographs whatever he finds before any price is agreed.

Valley gutter overflowing on your Streatham terrace?

Send a message and Patrick will get behind the parapet, check the central valley and photograph the lead so you see what failed.
