Local roofing company
A Hounslow roofer for repairs, reroofs and flat roofs
Delta Construction is based at 7 Southland Way, Hounslow. We cover Hounslow and nearby West London areas including Isleworth, Brentford, Feltham, Heston, Cranford, Chiswick and Ealing. The local mix of 1930s semis, terraces, extensions and older properties means the right answer can range from a targeted repair to a complete strip and reroof.
We look at the covering, underlay, battens, flashings, chimney details and visible structure before recommending the scope. If a sound roof only needs a repair, that is what we quote. See more about our work as builders in Hounslow.

Repair or replace? Straight advice first
A few slipped tiles on an otherwise sound roof normally point to a repair, not a complete replacement. A reroof becomes more sensible when the covering and underlay are near the end of their life, leaks keep returning in different places, or widespread defects make repeated patching poor value.
Our assessment separates the immediate cause of the problem from the wider condition of the roof. You receive a written scope, so you can see what is included before deciding.
Signs your roof needs attention
- Water stains on upstairs ceilings or in the loft after rain
- Slipped, cracked or missing tiles visible from the ground
- Daylight through the roof when you're in the loft
- Sagging in the roofline, or granules from tiles collecting in gutters
- Damp or crumbling mortar around the chimney
Any of these is worth a look before it turns into a bigger — and more expensive — problem. Left alone, a small leak rots timbers and ruins insulation and plaster below.

What a reroof costs, and how long it takes
A typical reroof on a London semi or terrace ranges from around £6,000–£15,000 depending on size, pitch, access and the covering you choose — concrete interlocking tiles at the value end, natural slate at the premium end. A standard reroof takes 5–8 working days, weather permitting: scaffold up, strip the old covering, replace felt and battens, lay the new tiles or slate, finish the leadwork and ridge. Repairs are far quicker and cheaper. Every job gets a fixed-price quote after we've actually looked at the roof.

Frequently asked questions
Should I repair or replace my roof?
A few slipped tiles on a sound roof is a repair. If it's 60+ years old, the felt has perished, or leaks keep returning, a reroof is usually more cost-effective. We advise honestly after a free assessment.
How much does a new roof cost?
Around £6,000–£15,000 for a typical London semi or terrace, depending on size, pitch, access and material. Repairs cost far less. Fixed-price quote after inspection.
How long does a reroof take?
Usually 5–8 working days for a standard semi or terrace, weather permitting.
Do you do flat roofs?
Yes — EPDM rubber, felt and fibreglass (GRP) for extensions, dormers and garages, with proper falls and detailing.
Is the work guaranteed?
Yes — workmanship guarantee plus manufacturer material warranties (15–30 years), and £2M public liability insurance.
