When roofing problems arise, we at Apex Roofing and Guttering Ltd provide Croydon homeowners with a comprehensive service backed by over three decades of experience in south London. Our work covers roof repairs, new and replacement roofs, flat roofing systems, chimney repairs, gutter installation and maintenance, and waterproofing. We also address storm-related damage, leaking joints, blocked downpipes, deteriorating pointing, damaged leadwork and other faults that can allow water into a property. Patrick oversees the work, ensuring that customers can deal with one team rather than having separate tradespeople manage different parts of the same project. To arrange a free roof inspection and receive a quotation without obligation, contact us on 020 8138 0918.
Transparency is central to our approach. Before asking you to approve any work, we inspect the affected area and share photographs of the problem, with video provided where appropriate. This enables you to understand the condition of your roof and the reason for our recommendations. We agree the price before starting, do not add hidden charges, and collect payment upon completion. Our flat roofing options include torch-on felt, Firestone RubberCover EPDM and GRP fibreglass, while our wider services include slate and tiled roofing, fascias, soffits and chimney lead flashing. We are fully insured, offer a 10-year guarantee with cover of up to 20 years depending on the job, and remove waste before leaving the property tidy. Our 5.0 Google rating reflects feedback from 30 reviewers.

Services
Our approach to roof repairs begins with a careful inspection to establish the source of the problem. Patrick takes photographs and shares them with you before any tiles are disturbed, allowing the fault to be seen clearly. We repair leaks, replace damaged tiles and slates, and refix ridges. Since water can follow battens and rafters, the indoor signs of a leak may appear some distance from its entry point. 
At Apex Roofing and Guttering Ltd, we believe roof replacement decisions should be based on clear evidence rather than unnecessary work. We offer a free inspection, photograph any problems and explain when repairing the existing covering remains sufficient or a complete replacement is needed. Our written quotation confirms the price in advance, without hidden charges. The work includes checking the timbers, fitting a breathable membrane and new battens, installing tiles or slates, and providing a guarantee appropriate to the job. 
Keeping a flat roof watertight starts with understanding the cause of the leak. We trace the route of incoming water, inspect vulnerable joints and drainage points, and identify any damaged covering or saturated decking. Once the fault has been explained and the price agreed, we undertake the appropriate repair using compatible materials. Photographs help you understand the work required, and payment is due only when the repair is finished. 
We specialise in replacing ageing roofs that suffer from recurring leaks, slipping slates, deteriorating tiles or sagging rooflines. Our inspection helps establish whether the covering has reached the end of its useful life and requires complete replacement. Each project includes a breathable membrane, fresh treated battens and your chosen tiles or slates, installed using appropriate fixing methods. We provide a 10-year guarantee, with cover extending up to 20 years depending on the job. 
We help homeowners address roofing emergencies caused by leaks, strong winds and damaged roof coverings. Patrick visits the property to examine the affected areas, determine the cause and take photographs for your records and insurance purposes. Before any repairs begin, we explain the work required and agree the price with you. Our initial priority is to stop water entering the property, with further repairs completed when conditions and materials allow. 
Apex provides roof damage repairs to address faults caused by prolonged weather exposure, frost, ageing and earlier work that has not been carried out properly. We deal with cracked tiles, perished felt and loose ridges, paying attention to problems that can develop unnoticed. Patrick photographs the affected roofing, explains the reasons for the damage and establishes an agreed price before undertaking repairs. 
We offer a complete gutter replacement service, taking down the old system and installing new uPVC guttering with matching downpipes. Customers can choose between half-round, square and ogee profiles, depending on the appearance and drainage requirements of their property. Our team checks the fascia boards, positions brackets accurately and tests every section with water. We remove the discarded materials and leave paths and driveways clear, with a 10-year guarantee that may extend to 20 years depending on the job. 
Our approach to chimney repairs combines a thorough inspection with clearly agreed costs. Patrick photographs the chimney pots, flaunching, brickwork and roof junction to establish where water is entering. We then carry out the required work, whether rebuilding mortar caps, securing pots, fitting cowls, repointing joints or renewing lead flashing. The price is agreed in advance, and we remove old mortar and clean the roof below before completion. 
We provide slate roof repairs and replacements for properties in Croydon and Streatham, with natural slate and slate-effect available for Victorian terraces and villas. As roofing materials age, slates can slip, crack or allow water to enter around the valleys. Repeated patches may indicate deteriorating nail fixings, particularly on older roofs, and payment is due after completion and site clearance. 
We specialise in repairing and replacing tiled roofs, including concrete interlocking re-roofs for 1930s semi-detached properties and repairs to traditional clay plain tiles. When concrete roof tiles become porous, we provide a roof survey and a free, no-obligation quotation in writing. As the protective coating deteriorates, tiles absorb rainwater, encourage moss growth and become heavier, increasing the risk of frost damage and cracking. 
Our approach to flat roofing centres on careful preparation and the installation of Firestone RubberCover EPDM. We inspect the roof deck, upstands and outlets, photograph the existing condition and calculate the requirements for a continuous rubber sheet. Any necessary decking or insulation work is included in the agreed price. Installed without naked flames, the finished covering withstands temperature fluctuations and ultraviolet exposure, with a 10-year guarantee and up to 20 years of cover depending on the project. 
Our GRP roofing service provides a robust, continuous fibreglass covering suitable for flat roofs that receive regular foot traffic or are visible from upstairs windows. We begin by inspecting the roof and explaining the proposed work before confirming the price. The installation includes a new OSB3 deck where required, reinforced resin laminate, pre-formed trims and a coloured protective finish. 
We provide felt roofing for extensions, garages and dormers, using a torch-on system topped with a mineral cap sheet. If your existing felt has developed cracks, blisters or leaks, Patrick shows you photographs of every split before you make a decision. Sunlight and frost gradually dry the material, and trapped air or water beneath a blister can lead to rain reaching the deck. 
Our uPVC fascia and soffit installations are designed to address deteriorating roofline boards without replacing sections that remain sound unnecessarily. We check each elevation, document areas affected by rot and explain which replacements are required before work commences. Damaged timber is removed, underlying rafter ends are inspected and any rotten sections are repaired. We fit ventilated soffits, secure new fascias to sound timber and refit the gutters, removing the old boards from the property. 
We renew damaged chimney and wall flashing using code 4 lead, removing the existing material and cleaning the joints before installation. Patrick documents the condition of the lead with photographs, including areas hidden behind the chimney, so the cause of the leak is clear. Once the work and price have been agreed, we complete the replacement and inspect and re-bed the surrounding roof tiles. 
When mortar joints begin to crumble or recede behind the brick face, repointing can help restore their protective function. We remove the old mortar from chimney stacks and brick walls before filling the joints with fresh material that matches the brickwork. Apex has over 30 years of experience and provides free quotations based on photographs. Depending on the work undertaken, our guarantees last between 10 and 20 years. 
Our approach to gutter repairs begins with a careful assessment of the whole run rather than concentrating solely on the visible leak. We provide photographs of the problem and explain which components require attention before agreeing the cost with you. Repairs may include replacing worn unions and stop ends, fitting additional brackets or renewing cracked sections. We test the water flow at the end and request payment only after the work is finished. 
With our gutter cleaning service, we address both accumulated debris and drainage problems identified during the job. Every gutter run is cleared, and the removed material is bagged rather than left across your garden. We flush the downpipes, clear obstructed swan necks and seal dripping joints. Before and after photographs document the results, and any larger issues are shown to you before further work is considered. 
Our storm damage repair service is designed to restore your roof's watertight condition as quickly as possible. Once the immediate risk of water ingress has been addressed, we record the damage photographically and explain the work required. We replace displaced roofing materials, secure ridges and hips, renew damaged lead flashing and repair flat roof felt, with the full cost agreed in writing beforehand. 
We install secure dry ridge systems and dry verge protection for gable ends in Croydon, removing the need for mortar bedding in these areas. Cracking can cause ridge tiles to loosen, while fragments of sand and cement falling from the roof may indicate gaps where rain can enter. Before agreeing on the work, Patrick presents photographs of the affected areas. Our completed projects exceed 400.
People
Patrick McDonagh
Owner
Patrick has spent over 30 years on roofs, and the way he works has not changed. When you call Apex, he comes out himself. He gets up to the problem, finds what is actually wrong and shows you the photos, and sometimes a video, before anything is agreed.
