On terraced streets, flat roofs are often found on the parts of a house you don’t see from the front: rear extensions, dormers and the roofs over bay windows. Because they sit below windows and against walls, the joins between the flat roof and the rest of the house are just as important as the covering itself.
All Round Roofing is family-run, with over 25 years in business. We’ll explain what’s wrong with your flat roof and whether a repair or a new covering is the better option.
Flat Roofing Services in Portsmouth
New Flat Roofs
We strip the old covering, check the deck beneath, and lay a new system chosen for your roof. EPDM rubber is our most popular option: a single-layer membrane bonded to a clean timber deck and finished with edge trims. Torch-on felt is our most economical system, liquid rubber suits roofs with awkward shapes, and GRP fibreglass is our most durable, top-of-the-range choice.
Flat Roof Repairs
Splits, blisters, lifted edges and leaking joints can often be repaired without replacing the whole roof. We find where water is getting in and fix it, and tell you honestly if the covering has reached the end of its life.
Roof Terraces
If you’d like to use a flat roof as a terrace, GRP fibreglass is an excellent choice, and it’s one of the most durable flat roofing systems available. Tell us how you plan to use the space and we’ll explain what’s involved.
Where Flat Roofs Usually Fail
Most flat roof leaks start at the details rather than in the middle of the roof:
- Where the flat roof meets a wall. The upstand and flashing along this join are a common entry point for water.
- Around windows and doors that open onto or sit just above the roof.
- At the edges and trims, where wind can lift a covering that isn’t properly secured.
- At outlets and gutters, where a blockage leaves water sitting on the roof.
- Where water ponds, putting constant strain on the covering in one spot.

Portsmouth Flat Roofing FAQs
My flat roof leaks where it meets the house. Is that the roof or the wall?
It’s often the join between the two: the upstand or flashing along the wall. We’ll check both and explain what we find.
Which flat roof system is best for a dormer?
It depends on the size, shape and condition of the roof. EPDM is our most popular choice, and liquid rubber can work well where there are lots of details to work around. We’ll recommend the right option after seeing it.
Can a flat roof be repaired rather than replaced?
Often, yes, especially if the damage is in one area. If the covering is failing across the roof, replacement is usually better value.
What guarantee comes with a new flat roof?
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).
