Here’s how we do it:
Every bay window flat roof we do is fully stripped back to the structural roof timbers. The existing bitumen felt flat roofing membrane is removed along with old timber roof deck.
We then fully fill the roof void with spray foam insulation. This serves three important functions: First it insulates the flat roof improving it’s thermal performance, second it seals it up, making it airtight and eliminating cold draughts and third it eliminates possible interstitial condensation issues which can be a big problem with cold deck flat roofs.
A new OSB3 Smart Ply flat roof deck is then installed with an improved flat roof fall to ensure efficient water run off.
The Firestone RubberCover EPDM single ply membrane is then fitted to the bay window flat roof making it watertight. This is achieved with a single sheet of Firestone RubberCover EPDM single ply membrane with no seams or joints.
The bay window flat roof is then completed with high quality Sure Edge gutter and edge trims as required.
Your new rubber roof comes with a 20yr membrane guarantee and a 40-50 year lifespan.
Bay window roof FAQ’s
-
Typically £800–£1,600, depending on what’s involved. The complicated end - upper-floor bays needing full scaffolding, lead work, slates lifted and reinstated — costs more, and our cost guide shows a real example of each. We can usually give you a ballpark over the phone.
-
Around a day. The simplest bays are done in half a day; an upper-floor bay with scaffolding and lead work can take two. Either way you’ll know before we start.
-
Usually, yes. We insulate the bay roof void and make it airtight as standard, which removes the cold surface condensation forms on. And if the real culprit turns out to be the wall rather than the roof - a missing cavity tray or failing pointing, we’ll diagnose that honestly and tell you, rather than selling you a roof that wouldn’t fix it.
-
Flat black rubber, in one piece, with neat uPVC edge trims and proper flashings into the wall. We won’t pretend it looks like slate — it looks like black rubber, because that’s what it is: neat, flat and tidy. Have a look at our recent projects and judge for yourself.
-
Yes, if the structure was safe to lean on before, the rubber is too. You can walk on it, ladders are fine, and there’s no real maintenance: you can wash it with normal cleaning products if it’s in your sightline, but hardly anyone ever does.
-
We’re fully insured, and if we cause a problem we fix it — though it rarely happens. If we ever need access on or beside a neighbour’s property, we make sure they know and we have their permission first.
