Replacing your flat roof in Northamptonshire? We install EPDM rubber, GRP fibreglass and torch-on felt systems with a full written quote and a 25-year workmanship guarantee.
A flat roof replacement is a significant investment - you want the right system fitted correctly, not just the cheapest option. Allied Builders explain the options clearly and give you a fixed price in writing.
Submit a quote request and a real local roofer rings you back during working hours - not a call centre.
Every quote is a fixed total in writing. No hourly rates, no surprise extras after work begins.
All flat roof replacements come with a 25-year workmanship guarantee. We also register manufacturer warranties on EPDM and GRP systems where applicable.
We know Northamptonshire's mix of stone cottages, Victorian terraces and modern estates. Our vans are based in Towcester and cover the whole county.
Real reviews from real Northampton homeowners.
"The work was carried out to a high standard. The two guys doing the work were polite and everything was cleared away at the end. Would recommend. Work was completed within the budget."
"Excellent service & advice, professional from start to finish, will not hesitate to use again or recommend"
"We had a leak coming into the kitchen, not sure where it was. Jo & Allied did a great job of repairing our roof and replace aged seals. The team working on the roof were very professional, friendly & also tidy. Can't recommend them enough, thank you!"
From first call to job done - here's exactly what happens.
We come out at a time that suits you, properly diagnose what's needed, and explain it in plain English.
You get a detailed quote in writing - total cost, exactly what's included, and how long it will take.
Booked-in date, professional team, clean site every evening, finished on the day we promised.
We check in once you're settled, register your 25-year guarantee (replacements) or 12-month guarantee (repairs), and we're a phone call away if anything's ever wrong.
