Services
Our roof repair service focuses on locating the source of leaks and addressing the damage accurately. Patrick examines the affected roof, takes photographs of the problem and shows you the findings before work begins. Water may travel along rafters and battens before appearing indoors, while fallen slates can indicate gaps that allow rain to reach the underlying membrane or exposed battens. 
We specialise in replacing roofs that have deteriorated beyond the point where individual repairs remain worthwhile. During our free assessment, Patrick checks the roof and loft, identifies underlying issues and provides photographs to support his recommendations. A fixed quotation is supplied in writing before any work starts, ensuring the agreed cost is clear. Every replacement includes suitable new roofing materials, a thorough structural check and a guarantee of 10 years, extending to 20 years depending on the job. 
We repair flat roofs by tracing water ingress back to its original entry point and addressing the underlying fault. Our inspection covers roof coverings, raised joints, drainage outlets and edge trims, helping us identify problems that may not be visible from inside. We use suitable methods for felt, EPDM and GRP, replace wet sections of decking where needed, and require payment only after the roof is watertight. 
Our roof replacement service is designed to address underlying problems rather than conceal them beneath another layer of roofing. We remove the existing covering down to the rafters, identify timber that needs attention and install new treated battens beneath a breathable membrane. Your chosen tiles or slates are then fitted securely, while the ridge, hips and verges receive a dry-fix finish. Scaffolding, materials, labour and removal of the old roof are included in the agreed price, with no additional hidden fees. 
We offer emergency roofing assistance when severe weather or sudden damage leaves your property exposed to rain. Following your call, Patrick visits the property to inspect the roof and identify the cause of the problem. Photographs help you understand the damage, while an agreed price ensures clarity before work commences. We make the roof watertight first and arrange any remaining repairs as required. 
We undertake roof damage repairs for roofs affected by natural deterioration, harsh weather and unsatisfactory previous work. Common issues include fractured tiles, failing roofing felt and unsecured ridge tiles. Our approach begins with a photographic record of the damage, followed by an explanation of its cause. Patrick then confirms the price with you before any repair work starts. 
We install new uPVC guttering and downpipes, providing a choice of half-round, square and ogee profiles to suit your property. Our process starts with accurate measurements, an inspection of the fascia boards and photographs of any issues requiring attention. Once you have selected your preferred design, we agree the price before ordering materials. We remove the previous system, test every run and provide a 10-year guarantee, with cover extending up to 20 years depending on the job. 
Tall chimney stacks require careful inspection because wind and frost can damage exposed mortar, pots and flashing. We rebuild cracked flaunching, secure loose pots, fit replacement cowls, repoint open joints and renew failed leadwork where necessary. Patrick accesses the chimney using appropriate roof equipment and photographs its condition for your review. You can see the areas requiring attention before approving a repair at one agreed price, with payment on completion. 
Our slate roofing service covers repairs and full replacements for Victorian terraces and villas in Croydon and Streatham. We offer natural slate alongside slate-effect alternatives, helping address common problems such as slipping tiles, cracks and valley leaks. On older roofs, displaced slates may indicate failed nail fixings rather than damaged stone, and payment is required once the work is complete. 
We help maintain the condition of tiled roofs through concrete interlocking re-roofs for 1930s semi-detached houses and repairs to clay plain tiles. Where surface deterioration has made concrete tiles porous, we carry out a survey before providing a written quotation free of charge and without commitment. Rainwater can penetrate the exposed sand as coatings disappear, encouraging moss and added weight, while frost may split the affected tiles. 
We provide EPDM roofing installations designed to replace deteriorating felt and older flat-roof membranes. Firestone RubberCover is fitted as one continuous sheet across most domestic roofs, avoiding the joints commonly associated with leaks. For properties requiring improved thermal performance, we can incorporate PIR insulation beneath the rubber covering. Our installations carry a 10-year guarantee, with periods of up to 20 years available depending on the work undertaken. 
We provide GRP fibreglass roofing for extensions, dormers and other flat roof areas where durability and appearance matter. The smooth coloured finish creates a neat surface when viewed from above, while the reinforced laminate is designed to withstand regular use. Patrick photographs the roof before work proceeds, agrees the price beforehand and ensures installation takes place in appropriate weather conditions. 
We undertake felt roofing work on extensions, garages and dormers, using torch-on felt and a mineral cap sheet. Patrick documents splits in your roof with photographs before you agree to proceed. Older felt can become dry and crazed after repeated exposure to sun and frost, leaving openings for water. Where a blister contains trapped air or moisture, a split can allow rain to reach the deck. 
We replace rotten timber fascias and soffits with durable uPVC boards, helping protect your roof from further deterioration. Patrick inspects every board around your property and photographs any areas affected by rot, allowing you to see exactly what requires attention. We provide a free quotation, agree the price beforehand and refit your guttering on completion, with payment due once the work is finished. 
We replace failed lead flashing around chimneys and walls to address the gaps through which rainwater can enter a roof. Existing lead is removed, the joints are cleaned, and new code 4 material is shaped into step flashing, a front apron and a back gutter as appropriate. Patrick provides photographs before the price is agreed, while our finishing process includes lead seal and checks to the surrounding tiles. 
At Apex, we provide professional repointing for chimney stacks and brick walls, carefully removing deteriorated mortar before applying fresh material to match the existing brickwork. With over 30 years of experience, we offer free quotations based on photographs. Our work is guaranteed for 10 years, with cover extending to 20 years depending on the job. 
We provide professional gutter repairs, addressing everything from leaking joints to entire gutter runs that have detached from the fascia. Patrick inspects the full system, identifies the underlying faults and photographs the damage for your review. Before work begins, we explain the necessary repairs and agree a clear price. Payment is only required once the gutter is running freely. 
Our gutter cleaning service covers every length of gutter around your property, removing leaves, moss, silt and other debris before bagging and taking all waste away. We unblock swan necks and flush every downpipe until water flows freely. Any dripping joints are cleaned, dried and sealed. Before and after photographs provide clear evidence of our work. 
We provide prompt storm and wind damage roof repairs, restoring watertight protection when tiles, ridges or flashing have been displaced or leaks develop. Our approach begins with securing the roof before completing the necessary repairs. We photograph all visible and concealed damage, provide a written quotation before work begins and require payment only upon completion. 
We provide dry ridge and dry verge replacement in Croydon for roofs where sand and cement bedding has cracked or begun to fall away. Our systems secure the relevant tiles using screws and clips, helping prevent the movement associated with loose mortar. Patrick first shows photographs of the existing damage, so the condition can be seen before an agreement is made. We have completed more than 400 projects.
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.
