A thorough roof inspection is one of the most effective ways to prevent leaks, structural damage and unexpected repair costs. At Dakdienst Nederland, we combine professional tools with proven inspection techniques to gain a complete picture of the condition of your roof, from the visible surface to the hidden underlying structure. This allows us to advise you accurately, plan targeted maintenance and extend the lifespan of your roof in a cost‑effective manner.
Unlike many providers in the Dutch market, where an inspection typically costs between €75 and €200 depending on roof size and accessibility, Dakdienst Nederland always performs the roof inspection itself completely free of charge. This means you receive professional advice and a detailed assessment without any obligation and without unexpected call‑out fees. Only any follow‑up work, such as repairs or renovations, will be charged, and always with a clear quotation in advance.
Below you will find a detailed overview of the essential tools and techniques our experts use during a roof inspection. Whether you have a flat bitumen roof, a pitched tiled roof, EPDM, PVC or a combination of these, this article will help you understand exactly what we look at, why we use certain tools, and how we ensure that no potential problem remains unnoticed.
Essential Roof Inspection Tools Used by Dakdienst Nederland
Dakdienst Nederland works with a carefully selected toolkit that combines traditional craftsmanship with modern measuring technology. Basic hand tools remain indispensable: stable roof ladders, roof hooks, measuring tapes, scrapers to test bitumen and sealants, and small hand brushes to clear away leaves or dirt so that details become visible. These simple tools make it possible to carefully inspect seams, overlaps, flashings and tile connections up close, without damaging your roof. Safety always comes first, so we only work with certified ladders and personal protective equipment.
In addition to hand tools, measuring and diagnostic instruments are increasingly important during a roof inspection. Moisture meters, for example, help to detect hidden moisture in insulation or wooden structures without the need for demolition work. Infrared thermometers can show temperature differences that sometimes indicate poor insulation or moisture problems. In the Dutch market, a specialised moisture survey or thermal imaging inspection can cost between €150 and €450, depending on the size and complexity of the roof. At Dakdienst Nederland, the basic use of these diagnostic tools as part of our regular inspection is included in our free inspection; only very extensive measurement reports or insurance‑grade surveys may involve additional costs, always in consultation.
Modern visual tools are also indispensable. High‑resolution cameras are used to document the condition of your roof and to create a clear photo report. This is particularly useful if you cannot easily access the roof yourself. Where possible and justified, we also use drones for aerial imagery, especially for large commercial roofs or complex residential roofs with difficult access. In the Netherlands, stand‑alone drone inspections often range from approximately €150 to €350, depending on location and flight time. When Dakdienst Nederland deploys such techniques, this is always discussed in advance and integrated transparently into any quotation, while the regular roof inspection itself remains free of charge.
Proven Techniques Our Experts Use to Assess Your Roof
During a roof inspection, our specialists at Dakdienst Nederland follow a structured step‑by‑step procedure to ensure that no part of your roof is overlooked. We start with a visual inspection from ground level: we look at the alignment of the roof, sagging, discolouration of the façade and any traces of leakage on gutter boards or window frames. Then we move to the roof itself, where we systematically work from ridge to eaves (on pitched roofs) or from the highest to the lowest point (on flat roofs). This allows us to follow the natural water flow and identify all vulnerable points such as penetrations, skylights, chimneys and roof edges.
A second important technique is the functional water and drainage assessment. Our inspectors always check whether the roof drains, gutters and downpipes are clear, sufficiently dimensioned and properly sloped. We look not only at obvious blockages, such as leaves and branches, but also at subtle issues like incorrect sealing of outlets or sagging gutters that may cause standing water. On flat roofs, we check for so‑called “ponding water” – puddles that remain after rain – which can significantly shorten the lifespan of the roofing material. If desired, we can simulate light water load, for example by controlled wetting of certain areas, to see how quickly and where water drains.
In addition, we use targeted testing and detailed examination techniques. With gentle pressure tests, we check whether insulation feels soft or spongy, which may indicate rot or moisture. At tiled roofs, we carefully lift a number of tiles to assess the condition of the underlying waterproof membrane, battens and any ventilation. At flat roofs, we inspect all seams, overlaps and terminations for hairline cracks, blistering, loose patches and UV damage. Where justified and with your permission, we may conduct small, minimally invasive test openings in the roof structure to assess the condition of insulation and wood from the inside; such in‑depth diagnostic work in the Netherlands typically ranges from €150 to €400, depending on the scope. For precise pricing of any extensive investigative work or subsequent repairs, we always advise contacting Dakdienst Nederland directly so that we can provide a tailored and transparent quotation.
A professional roof inspection is more than a quick look at a few tiles or a brief walk across a flat roof. With the right combination of tools and techniques, Dakdienst Nederland is able to map both visible and hidden defects, assess risks for the coming years and give clear advice on maintenance, repair or renovation. Our free inspection ensures that you receive this expertise without any financial threshold, while any follow‑up work is quoted transparently and tailored to your situation.
Whether you are dealing with recurring leaks, ageing roofing, storm damage or simply want clarity about the condition of your roof before selling or renovating, an in‑depth inspection offers valuable certainty. By using modern measuring instruments, detailed visual documentation and a structured inspection method, we can accurately indicate what is necessary now, what can wait and which preventive measures will save you money in the long term.
If you would like to know what the condition of your roof is, what options you have and what the realistic costs are for your specific situation, we recommend contacting Dakdienst Nederland directly. Our experts will schedule a free roof inspection, explain the findings clearly on site and provide you with a detailed and non‑binding proposal for any follow‑up steps, always in line with the Dutch market prices and your personal wishes.
