When a Flat Roof Needs Replacing

Blisters, splits, lifted edges and water sitting in pools after rain all point the same way. Old felt roofs harden and crack with age and sun. Once water has been getting in for a while the deck below goes soft and patching stops holding.

Choosing the Right Covering

Fibreglass gives a seamless finish with no joins to fail. Rubber membranes go down in one sheet and cope well with movement. High performance felt is laid in layers and is the cheaper option. Size, shape and budget decide which suits your roof.

Drainage and Falls

No flat roof is truly flat. It needs a slight slope so water runs to the outlet instead of sitting there. Standing water is what kills a roof early. We build in the fall with firrings when we replace the deck and set the outlets to match.

Frequently Asked Questions

How long does a flat roof last?

Older felt roofs often need replacing after about fifteen to twenty years. Rubber and fibreglass systems typically last longer when laid on a sound deck with proper falls. Keeping outlets clear of leaves and moss makes a real difference to how long any flat roof lasts.

Can you replace a garage roof in Chatham quickly?

A standard single garage roof is usually a one to two day job once we are on site. Stripping the old covering, replacing any soft boards and laying the new system all happen in the same visit. We work around the weather, since nothing is laid onto a wet deck.

Do I need building regulations for a flat roof replacement?

If more than half the roof surface is being renewed, building regulations usually apply and insulation has to be brought up to current standards. Small repairs do not. We tell you which side of that line your roof falls on before we price the work.
