Before you ask
Questions people ask
Why does water sit on my flat roof?
Usually the fall is too shallow or the deck has sagged. A little standing water after rain is common, but a puddle that stays for days needs looking at.
Does a new flat roof always need a new deck?
No. If the deck is dry and firm it can stay. If it is soft or damp, it has to be replaced. We check before quoting.
Which flat roof is best for a Kempston garage?
It depends on size and how much you will see it. Felt is often fine for a garage, while GRP or EPDM suit roofs you look down on. We will advise on yours.

More about flat roofs in Kempston
What is actually under a flat roof
Most people only see the top layer of a flat roof. Underneath, it is a stack of parts, and any of them can be the reason it leaks. Knowing the layers makes it easier to understand a quote, so here they are from the bottom up.
- Joists, the timbers spanning the room below
- Firrings, tapered strips that give the roof its fall so water runs off
- The deck, boards fixed over the top
- Insulation, on some roofs, above or below the deck
- The waterproof layer, felt, GRP or EPDM
- Trims and edges, where most of the detailing happens
When a flat roof feels spongy or a puddle never drains, the problem is often the deck or the fall, not only the top layer. Laying a new covering over a wet deck is a waste of money.
Kempston flat roofs we see
Garages at the back of terraces, single-storey kitchen extensions on post-war semis, porches and bay tops, and the occasional dormer. Older ones are usually felt that has blistered and cracked after years of sun.
The three coverings in short
- Felt: layered and familiar, sound on garages and outbuildings
- GRP fibreglass: a jointless, hard-wearing finish that looks neat from above
- EPDM rubber: one flexible sheet with almost no joints, good on larger areas
We will recommend one and say why, based on your roof rather than a favourite product.
Decisions worth making before we start
Do you want more light?
We fit opening skylights into flat roofs. It is far easier while the roof is being replaced than adding one later.
Where does the water go?
A flat roof needs a sensible fall and a proper outlet into a gutter. We check both and correct them if they are wrong.
Does it meet the house properly?
Where the roof joins a wall, it needs a proper upstand and a lead or trim flashing above it. This is one of the most common leak points on extensions.
Your written quote
It names the covering, says whether the deck is being replaced, lists trims, flashings, skylights and waste removal, and comes with photos of the old roof.
