A Roofing Team You Can Speak To Directly
Alliance Roofing London carries out roof repairs, replacements and specialist waterproofing for homeowners, landlords and property managers across London, Surrey and Berkshire. With more than 22 years in roofing, the business works on the parts of a building that owners often cannot see closely for themselves. Our responsibility is to explain the condition, agree a sensible scope and make the finished work understandable.
Some enquiries start with a drip after heavy rain. Others begin with plans for a new extension, a worn flat roof or a roof terrace that is no longer keeping the room beneath it dry. We do not treat these as the same job. The covering, the structure beneath it, the drainage and the way the property is occupied all matter. A repair should address the cause; a replacement should have a clear reason.
Work Kept In-House
Our roofing work is carried out by our own team rather than subcontracted to another roofing firm. The owner oversees the work and carries out the final sign-off. This matters when a project involves more than one roof detail, such as a pitched slope meeting a flat extension, a chimney surrounded by leadwork, or a balcony with both waterproofing and a walking surface.
Keeping those conversations together helps the customer understand who is responsible for the agreed work. It also means a detail found after a covering is removed can be discussed as part of the same project. We explain the issue and its implications rather than assuming that a photograph or a technical name is enough for an owner to make a decision.
Traditional Coverings And Modern Waterproofing
Our service range includes slate and tiled roofs, flat roofing, leadwork, chimney repairs, guttering and roofline work. Flat-roof options include EPDM rubber, GRP fibreglass, torch-on felt and liquid-applied waterproofing. Each system has its place. The choice depends on the roof build-up, movement, available height, drainage details and whether the surface will be walked on.
On an older roof, matching the covering and the weathering details can be important to the appearance of the building. On an extension or larger renewal, insulation and ventilation need to be considered alongside the visible finish. Where Building Control involvement is required, we can help coordinate that part of the project. The exact requirements should be confirmed for the work being proposed.
Planning Access And Protecting Your Property
A roof cannot be assessed properly from a price list. Its height, shape, covering and access all affect the work. A rear extension reached through the house needs a different plan from a front slope beside a public pavement. Tell us about narrow side passages, shared gardens, basement lightwells, parked vehicles and any part of the property that must remain in use. These details help establish how materials and removed roofing can be handled without creating an avoidable obstruction.
Where scaffolding or another access arrangement is needed, that should be identified in the scope before the work is booked. For a flat, leasehold property or shared roof, the person commissioning the work may need to involve the freeholder, managing agent or neighbouring owner. Please tell us who can approve the works and provide access. We can then discuss the roof with the right person and avoid agreeing work on an area that is outside your responsibility.
What Your Roofing Quote Should Cover
The visible surface is only part of a roofing job. A useful quotation describes the affected roof section, the preparation, the proposed materials and the treatment of adjoining details. Access, removal of old materials and waste handling should be clear. Where damaged timber or a wet deck may be concealed, the quote should explain what can be assessed beforehand and how additional findings will be discussed. You should not have to infer what is included from a single line and a total price.
Compare the proposed work as well as the figure. One quote may cover a small repair while another includes renewal of the surrounding covering or drainage details. Ask why each option is being recommended and what will remain untouched. A larger project may also require decisions about insulation, ventilation, rooflights or the finished roof height. Those decisions belong in the planning conversation, before materials are ordered or a roof is opened.
From The First Visit To The Final Check
Alliance Roofing London keeps its roofing work in-house. The owner oversees projects and the final sign-off, giving you a point of accountability for the agreed work. Before starting, we discuss access, the area being repaired or replaced and the arrangements for keeping the property protected. If opening up the roof reveals a condition that changes the scope, the finding needs to be explained before a different course of work is agreed.
At completion, the useful question is not simply whether the roof looks new. The repaired junctions, drainage routes and any adjoining surfaces should be checked, and removed materials should be cleared from the working area. Ask what has been repaired, what has been retained and whether any separate maintenance remains. Keep the written scope and any photographs together, especially if you are looking after a rented property or coordinating work for other owners.
Looking After The Roof Afterwards
Keep an eye on the roof from ground level after strong winds or sustained rain. A new damp patch, overflowing gutter or displaced piece of covering is worth reporting before the next wet spell. Do not climb onto the roof to investigate, and do not assume a flat roof or rooflight can take your weight. Photographs from a safe window or the garden often provide enough information for an initial discussion.
Regular checks should suit the roof rather than follow a generic treatment package. Trees can increase the amount of debris reaching gutters and outlets, while a roof terrace needs its drainage kept clear beneath or around its walking surface. Tell us about previous repairs and keep notes on when a leak appears. That history can help separate a new fault from moisture that is still drying out after an earlier leak.
