Service overview
What new roofs & roof replacements involves, and why it matters
What it is
A roof replacement means stripping the existing covering back to the rafters and rebuilding it properly: new breathable membrane, new treated battens, new or reclaimed slates or tiles, fresh ridge and hip work, and all the flashings and edge details that keep water out. It is not a cosmetic job. It resets the clock on the most important part of your home's weatherproofing.
Who it's for
It suits homeowners whose roof has reached the end of its working life, those who have paid for repeated repairs that keep failing, and anyone buying or renovating an older property where the survey has flagged the roof. It also suits extensions and loft conversions where the existing roof no longer matches what the house needs.
When you need it
Signs it is time include widespread slipped or cracked tiles, sagging between rafters, daylight visible in the loft, damp patches in several rooms, nail fatigue (tiles sliding even after refixing) and old bitumen felt that has perished and torn. If more than a small area is affected, replacement is often better value than chasing individual leaks.
Why use a professional roofer
A roof is a system. If the battens, membrane, fixings and flashings are not done correctly, a brand-new tile looks fine for a year and then lets water in. Billy assesses the whole roof, shows you photos of what he finds, and only recommends a full replacement when the roof genuinely needs it. Julia C described not being sold an unnecessary roof or chimney replacement on her job.
The cost of waiting
What happens if you leave it
An ageing roof rarely fails all at once. It fails slowly, and the damage spreads out of sight long before you see a stain on the ceiling.
Hidden timber rot
Water that gets past the tiles soaks into battens, rafters and wall plates. Once timber rots, the repair moves from roofing to structural carpentry, and the bill climbs quickly.
Ceiling and insulation damage
Wet loft insulation can perform less effectively. Plasterboard ceilings stain, sag and can collapse. Internal damage may add to repair costs.
Damp, mould and health
Persistent moisture brings mould into bedrooms and lofts, which affects air quality and can make the house harder to heat and harder to sell.
Money spent on repeat repairs
Paying for a patch every winter on a roof that has reached the end of its life is money that could have gone towards a replacement with a 20-year guarantee.
Common mistakes homeowners make
- Choosing the cheapest quote that skips the membrane, battens or proper ridge work
- Covering an old roof with a coating instead of fixing the cause
- Waiting until a storm forces a rushed decision
- Not asking what the guarantee actually covers

Discuss the roof condition, access and proposed work with Billy.
- 3

Confirm materials, timing, payment arrangements and how any additional work would be agreed before accepting.

Guarantee terms
New pitched roofs carry a 20-year guarantee. Flat roof guarantee length varies by system. Ask what terms apply to this job.
Benefits and considerations
Results depend on the roof condition, specification and work agreed. Customer feedback describes individual jobs, not a guarantee of the same outcome. Ask for the scope and applicable guarantee terms in your quote.
One job, done properly
A replacement may be appropriate where a roof is extensively worn. The exact scope depends on the agreed specification.
20-year guarantee
New pitched roofs from BMB Roofing come with a 20-year guarantee, ask Billy for the terms and exclusions that apply.
The price you were quoted
Reviews repeatedly mention paying exactly the quoted price. Any genuine extra work is explained before it is done.
Safer home
Sound battens and appropriate fixings can reduce the risk of loose tiles. No roof is immune to severe weather.
Warmer, drier loft
Modern breathable membranes reduce condensation and protect your insulation so it keeps working.
Added value
A new roof removes one of the biggest worries for buyers and surveyors when you come to sell.
In detail
Materials and methods to discuss
These are general roofing considerations, not a confirmed specification for every job. Materials, matching, access and installation details need to be agreed with Billy for your roof.
Every house is different, so we tailor the specification to your roof's pitch, exposure, existing materials and any planning considerations.
Slate roofs
Natural slate is long-lasting and suits period properties across the Chilterns and Thames Valley. We fix slates with the correct nails or hooks at the right gauge for the pitch, The availability of matching or reclaimed slate needs to be confirmed for your job.
Tiled roofs
Concrete and clay tiles, including plain tiles and interlocking profiles, are common across Hertfordshire, Buckinghamshire and Berkshire. We match the profile and colour to your street where possible and fix to current standards so tiles resist wind uplift.
Membranes, battens and ventilation
Old bitumen felt often tears and sags. We replace it with breathable membrane and new treated battens, and make sure the roof space is ventilated so condensation does not build up in the loft.
Ridges, hips, valleys and edges
Edges and junctions can be sources of roof leaks. We can bed ridges and hips in mortar or fit dry ridge and dry verge systems, and we renew valleys and leadwork so the whole roof is consistent.
Partial re-roofs and extensions
Sometimes only one elevation needs replacing, or an extension needs tying into the main roof. We assess whether a partial re-roof will give you a sound result and tell you honestly if it will not.

"I was impressed by the two man team who looked at the roof edge and chimney problem and assessed what action was needed. They did not try and sell me a new roof or new chimney but were very honest and efficient. A price was quoted and a date set. They turned up on time and cleaned up after them and I paid the quoted price. They were also helpful and engaging. I would heartily recommend them. They did a good job.…"
