How to check the condition of the roof structures?
Checking the condition of the roof and its structures is an important part of building maintenance: it helps you catch damage early, prevent costly repairs and extend the life of the roof. Below is a simple checklist you can follow yourself, and when to call in a professional.
1. External inspection
Start with a visual inspection from the outside. If possible, climb safely onto the roof, or use binoculars or a ladder to get a good view without climbing up.
- Go over the entire roof surface and look for damage such as cracks, tears, loose or missing roof tiles or sheets, and moss growth.
- Pay special attention to the edges of the roof, ridges, valleys and any through-holes, such as the seals around the chimney or ventilation pipes, as these spots are more susceptible to leaks.
- Check gutters and roof bridges as well, since debris or damage there can also point to problems with the roof.
2. Internal inspection
Go into the attic or upper floor and check the underside of the roof structures.
- Look for signs of water damage, such as yellowed or bulging roof panels, dark stains, or mold growth and its smell.
- Check the roof structures themselves, such as rafters, beams and the underlay, for signs of rot or moisture damage.
3. Moisture measurements
Moisture is one of the biggest causes of damage to roof structures. A moisture meter lets you check whether there is excessive moisture inside the structures, especially in areas where you have already noticed visual signs of leaks or dampness.
4. Regular maintenance
Maintaining the roof requires regular upkeep: remove debris and moss, clean the gutters, and repair any damage as soon as it is discovered. Regular maintenance helps prevent major problems and extends the life of the roof.
5. Consulting a professional
If you suspect that the condition of the roof is poor, or simply want to be sure, ask a roofing professional to inspect it. A professional can identify hidden problems that are easy to miss, assess the roof’s remaining durability, and recommend the necessary repairs. Regular inspection and maintenance, whether done yourself or by a professional, helps prevent major damage and can save you money in the long run.
