With Apex Roofing and Guttering Ltd, Croydon homeowners can arrange roofing repairs, replacements and maintenance through a team with more than 30 years of experience working across south London. We cover the principal elements of residential roofing, including pitched roofs, flat roofing systems, chimneys, gutters and waterproofing. Whether a property has suffered storm damage, developed a leak, requires a new roof or needs attention to deteriorating guttering, we can assess the fault and recommend the appropriate work. Our flat roofing services include felt, EPDM rubber and GRP fibreglass, while our other work extends to chimney repointing, lead flashing, gutter cleaning, gutter replacement, fascias and soffits. Patrick manages the service, keeping the various elements of a roofing project under one team. Contact us on 020 8138 0918 for a free quotation without obligation.
We understand the importance of knowing what work is necessary before making a financial commitment. For that reason, Patrick shows customers photographs of the identified problem before agreeing a price and may provide video evidence where helpful. This approach enables homeowners to see the fault rather than depend on a verbal estimate alone. Our quotations are agreed in advance, with no hidden or unexpected fees, and payment is made when the job is complete. We are fully insured and provide a 10-year guarantee, with the possibility of cover extending to 20 years according to the job. Once work is finished, our team removes the waste and tidies the site. We have completed over 400 projects and hold a 5.0 rating from 30 Google reviews. Our commitment is to provide reliable roofing and guttering services with clear information, agreed pricing and attention to the condition of each property.

Services
We investigate roof leaks thoroughly, recognising that the place where water appears inside may not correspond with the opening in the roof. Patrick identifies the fault, photographs it and presents the evidence before repairs commence. Our services include replacing tiles and slates and refixing ridge tiles. Where a slate has fallen, rain may penetrate gaps and reach the battens or membrane, if one is present. 
Our service provides a complete roof replacement for properties affected by persistent leaks, deteriorating tiles, failing slate fixings or damaged roofing felt. We start with a complimentary inspection and share photographs of the issues discovered across the roof and loft. After explaining our recommendations, we issue one agreed price in writing before work commences. Replacement involves stripping the roof back to the rafters, checking the timbers, fitting a new membrane and battens, and installing the selected tiles or slates. 
A leaking flat roof can allow water to travel beneath its covering before appearing inside your property. We investigate the ceiling below and inspect the roof, including its drainage outlets, edges and flashings, to establish the cause. Our repairs are tailored to the roofing material, and we provide photographic evidence before work is agreed. The price is confirmed beforehand, and you pay after completion. 
We help homeowners determine when repeated repairs should give way to a complete roof replacement. Multiple slipping slates, porous tiles, recurring leaks and an uneven roofline can indicate wider deterioration that individual repairs will not resolve. Our inspection covers the roof structure and loft, with photographs provided to explain any concerns. We then offer an agreed price for the full installation, using a breathable membrane, treated battens and suitable tiles or slates, together with a guarantee of at least 10 years. 
A damaged roof can quickly lead to water entering ceilings, lofts and extension roofs, making timely repairs important. We inspect roofing problems such as torn felt, missing slates, displaced ridge tiles and unstable chimney components. Patrick personally evaluates the damage and supplies photographs to explain the situation. Our team agrees the cost with you before proceeding, clears away the resulting debris and accepts payment upon completion. 
We help put roofs back into sound condition by repairing damage associated with ageing, weather and previous poor workmanship. Cracked tiles require attention because even small fractures can allow water through to the underlying felt. Our repairs also cover deteriorated felt and loose ridges. Patrick records the damage in photographs, explains what caused it and agrees the price before starting. 
We provide professional gutter installation, removing existing systems and fitting new uPVC gutters and downpipes in half-round, square or ogee profiles. Our team carefully measures each section, checks the fascia boards and agrees the price before ordering materials. Every installation is water-tested, and our work carries a 10-year guarantee, extending to 20 years depending on the job. 
Protecting your property begins with identifying faults at the top of the chimney. We repair deteriorated flaunching, refix loose pots and cowls, restore open mortar joints and replace defective lead flashing. Patrick uses a roof ladder or scaffold to access the stack safely, records its condition in photographs and explains what requires attention. You receive one agreed price before work starts and pay when it is finished. 
We repair and replace slate roofs on Victorian terraces and villas, offering both natural slate and slate-effect options. Ageing roofs in Croydon and Streatham can develop slipped slates, cracks and leaks around the valleys. Our work addresses these problems, with payment due only upon completion, once the roofing work is finished and the site has been cleaned. 
Apex undertakes roof replacement and repair work for tiled properties, including concrete interlocking systems on 1930s semis and traditional clay plain tile coverings. Porosity in concrete tiles can be assessed during our roof survey, which is followed by a free, no-obligation estimate in writing. As protective coatings wear down, exposed sand absorbs moisture, moss takes hold and the tiles become heavier, leaving them susceptible to frost-related splitting. 
We specialise in fitting EPDM rubber coverings for flat roofs that have suffered from recurring leaks, damaged felt or persistent maintenance problems. The Firestone RubberCover membrane spans most house roofs in a single sheet, helping remove vulnerable overlaps. Where necessary, we can replace damaged decking and add PIR insulation. Our pricing is agreed before work begins, payment is made on completion, and every roof is guaranteed for 10 years, with longer cover available up to 20 years depending on the job. 
We install seamless GRP fibreglass coverings for flat roofs that need a hard-wearing, practical finish. Where older fibreglass has developed cracks, we assess the deck and its movement before arranging suitable preparation and relaying. Every project is priced before the resin is mixed, and the work is carried out during a dry spell to support proper curing. Our flat roofing work is fully guaranteed. 
For extensions, garages and dormers, we install torch-on felt roofing finished with a mineral cap sheet. Our process includes photographing the roof before any work is agreed, so Patrick can show you the splits present in the covering. Sunlight and frost gradually dry out older felt, causing cracks, while blisters formed by trapped air or water can break and permit rain to penetrate the deck. 
At Apex, we install replacement uPVC fascias and soffits to restore protection around your roofline. During our inspection, Patrick records damaged sections photographically and checks the condition of the boards throughout your property. We also examine the rafter ends for decay, replacing affected timber where necessary. Ventilated soffits help maintain a dry roof space, while refitted guttering directs rainwater into the drainage system as intended. 
When lead flashing begins to split, lift or allow rainwater through, we provide a practical replacement service using new code 4 lead. Patrick photographs the affected areas before we agree on any work, helping you understand whether the lead or its supporting mortar has failed. We fit the necessary flashing, secure its upper edges within the brick joints and apply lead seal to help prevent water ingress. 
We specialise in restoring mortar joints on chimney stacks and brick walls through our repointing service. Existing mortar is raked out and replaced with fresh mortar selected to complement the brickwork and help keep rainwater out. Drawing on more than 30 years of experience, we provide free photo-based quotations and guarantees of 10 years, or up to 20 depending on the work. 
We specialise in restoring leaking and damaged gutters, whether the fault affects one joint or a complete section of the system. Patrick checks the guttering thoroughly, documents any defective seals, broken lengths or loose supports, and explains the proposed solution. We replace damaged components, improve bracket support where necessary and restore the correct fall. A water test confirms drainage before we finish, with payment made on completion. 
We clear gutters carefully from front to back, removing moss, leaves, silt and other accumulated material without tipping it onto your garden. Blocked outlets and swan necks are dealt with, and every downpipe is flushed until water emerges freely at the bottom. Leaking joints are cleaned and sealed during the visit, with photographs supplied to demonstrate the work completed. 
When severe weather damages your roof, we act quickly to prevent further water ingress and carry out lasting repairs. Our work covers missing tiles and slates, loosened ridge tiles, damaged flashing and torn flat roof felt. We document the damage with photographs, agree the full repair cost in writing beforehand and ensure the roof is watertight before proceeding with permanent restoration. 
When mortar begins falling from your roof ridge or gable end, gaps can develop and allow rainwater to enter. We provide dry ridge and dry verge installations in Croydon, replacing cracked bedding with screwed and clipped systems. Patrick presents photographs of the damage before any work is agreed, and our experience includes more than 400 completed projects.
People

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.
