Flat Roof Installation and Repairs
Is your flat roof leaking or in need of a complete upgrade?
I install and repair flat roofs across Bolton and Greater Manchester with reliable workmanship and clear pricing.
Flat roofs need the right materials and a careful installation to stay watertight. When a flat roof starts to crack, pool water or let moisture through the joints, it can damage plaster, ceilings and insulation. I install and repair flat roofs across Bolton, Bury, Chorley, Astley, Leigh, Atherton, Horwich and Adlington using felt, EPDM rubber and GRP systems.
I prepare the roof deck, remove any rotten boarding and fit new coverings that are durable and low maintenance. Whether you need a small repair or a complete replacement, I offer clear advice and a reliable service.
Common Reasons To Replace A Flat Roof
Customers usually come to me with the same set of issues. If any of these sound familiar, you are in the right place.
- Blistering or cracking across the surface
- Water pooling for long periods after rain
- Leaks around joints, upstands or skylights
- Felt lifting at the edges or perishing from age
- Poor insulation causing heat loss
- Preparing for a new extension or refurbishment

FAQ
How Long Does A Flat Roof Replacement Take?
Most flat roof replacements take between one and three days, depending on the size of the roof, the materials being used and whether any of the decking needs replacing. Smaller garage or porch roofs can often be completed in a single day.
Can You Install Roof Insulation At The Same Time?
Yes. Flat roof insulation is normally fitted during a replacement because it is easier to access the decking. Adding insulation reduces heat loss, improves comfort and helps prevent condensation inside the roof space.
Do Flat Roofs Always Leak?
No. A flat roof that is installed correctly with good drainage should stay watertight for many years. Leaks usually happen when old felt starts cracking, when water pools for long periods or when joints and edges fail. Modern flat roof systems are far more durable.
How Much Does A Flat Roof Cost?
The price depends on the size of the roof, the materials you choose and the condition of the existing decking. Once I have inspected the roof, I provide a clear quote that sets out all costs so you know exactly what is involved.
