Our Roofing Services

Every job is completed by trained, fully insured roofers who follow industry standards from survey to sign off. We specify quality materials, explain your options in plain English and deliver weatherproof results that last.

New Roof Installations

We design and install new roofs with care for every layer, from breathable underlay and graded battens to correctly fixed tiles or natural slate. Ventilation, ridge detailing and leadwork are finished to specification. Your new roof is photographed before and after, and covered by our written workmanship guarantee.

Pitched Roofing

From full re roofs to isolated tile replacement, our pitched roofing service blends traditional craft with modern components. We match profiles and colours to Chesham property styles, set out courses accurately and secure ridges and verges for long term performance.
Enquire Now

Flat Roofs

We install and repair GRP fibreglass, torch on felt and EPDM flat roofs. Falls are checked for drainage, outlets are correctly sized and trims are sealed for a clean finish. Where suitable, we can overlay sound decks to reduce cost, always confirmed in writing after inspection.
Enquire Now

Roof Repairs

We fix leaks, slipped or broken tiles, damaged flashings, failed ridges and valleys. You receive photos of the fault and an itemised quote before work starts. Most minor repairs are completed the same day where safe access allows.

24/7 Emergency Roofing

Sudden leak or storm damage. Our team makes the roof safe and watertight, then returns for permanent repairs once conditions are suitable. You get temporary weathering, a clear plan and a fixed price for the follow up works.

uPVC Fascias, Soffits and Cladding

Low maintenance roofline systems protect your rafters and improve airflow. We supply and fit uPVC fascias and soffits in a range of finishes, with bird guards and ventilation where needed. Old timber is assessed and replaced if required.
Enquire Now

Guttering

We install and repair uPVC and aluminium gutters, downpipes and guards. Alignment and joints are checked with a water test so rain is carried away from brickwork and foundations. We also clear and flush existing systems.
Enquire Now

Chimney Repairs and Leadwork

Repointing, new flashings, back gutters and soakers are completed to stop water tracking. We also remove redundant stacks where requested and cap unused pots to reduce ingress while maintaining ventilation.
Enquire Now

Spray Foam Removal

We carefully remove old spray foam to restore roof breathability and inspect timbers. If required, we replace affected sections and install a breathable underlay so the loft stays dry and compliant with modern standards.
Enquire Now

Moss Removal By Hand

Hand scraping protects tiles. We follow with a biocide wash to slow regrowth and improve drainage. This is only carried out once any defects are repaired, so cleaning does not mask issues.
Enquire Now

Why Homeowners Choose Us?

We know the stereotype. Pushy quotes and messy sites put people off. Our approach is different. You get photos with your survey, a clear written price, agreed start dates and respectful clean ups. We are fully insured, trained to work at height and back our work with written guarantees.

Removal of Chimney stack, replacement of roof underlay, guttering and flat roof repair. - Mitchell from Alliance Roofing & Building was the only builder, of many that I had contacted, that climbed a ladder to inspect my flat-roof and to climb into my loft-space to inspect the main roof from the inside. After an extensive review of my property and discussing my options, he emailed me his quotation on the same day. Booking in dates for Alliance & Roofing to commence work was quick and effortless. They arrived on time, completed the work as planned to a professional standard. Provided Photos of work carried out at all stages. I highly recommend Alliance Roofing & Building.
