Flat Roofing in Havant

Signs Your Flat Roof Needs Attention

• Standing water that stays on the roof for a long time after rain.
• Blisters or bubbles in the covering, where moisture or air is trapped underneath.
• Cracks and splits, especially in older felt.
• Lifted or loose edges around the perimeter or trims.
• Moss or plants growing on the surface.
• Damp patches or stains on the ceiling below the flat roof.
• A spongy feel underfoot, which can mean the timber deck beneath has got wet.

One sign on its own doesn’t always mean a new roof, but it’s worth having it looked at before winter.

Repair or Replace?

A localised split, a lifted trim or a single failed joint can usually be repaired. Replacement tends to make more sense when the covering is cracking or blistering across the whole roof, when it has been patched many times, or when water has soaked into the deck. We’ll show you what we find and explain both options where both are realistic.

The Flat Roof Systems We Install

EPDM Rubber

Our recommended and most popular option, and mid-priced: a single sheet of rubber membrane bonded to a clean timber deck, with edge trims for a tidy finish.

Torch-On Felt

A three-layer felt system, torched on as a safer alternative to hot bitumen, with a mineral cap sheet in black or red. It’s our most economical option.

Liquid Rubber

A liquid-applied, watertight coating that suits roofs with complex shapes where a lower-cost solution is needed.

GRP Fibreglass

Glass-fibre matting set in resin and finished with a topcoat. It’s our most expensive system, one of the most durable available, and an excellent choice for roof terraces.

Our main flat roofing page has more detail on each system.

Havant Flat Roofing FAQs

Is standing water on a flat roof a problem?

Some water after rain is normal, but water that stays for a long time puts constant strain on the covering and can find any weak point. It’s worth having it checked.

Why is my flat roof blistering?

Blisters usually form where moisture or air is trapped beneath the covering. Small, isolated blisters can sometimes be repaired; widespread blistering often means the covering is failing.

Do you replace garage and porch roofs?

Yes. We repair and replace flat roofs on garages, porches, extensions and dormers.

How long is a new flat roof guaranteed?

Up to 20 years, depending on the system: 20 years for EPDM rubber; up to 20 years for torch-on felt, depending on the felt used; 20 years for GRP fibreglass, provided the top coat is renewed every three to four years; and 10 years for liquid rubber (20 years when combined with fibreglass and maintained).

Is the quotation free?

Yes, always, with no obligation.
