Roof inspections: A closer look

Common roof problems and how to fix them

Your roof not only provides shelter but it also protects your home structure from elemental damage. Therefore, it is important to keep your roof well maintained for many years to come.

We recommend to carry out roof inspection and maintenance twice a year. This should be sufficient to ensure that your roof can withstand extreme heat and thunderstorms. Here are some tips on minor repairs and identifying potential problems.

A clean roof all year round

Roofs provide an ideal growing conditions for algae, moss, mushrooms and even tree seedlings. Fortunately, there are easy ways to prevent that. For starters, you can use a broom or long brush (avoid the ones with metal bristles) to clear away loose debris. If your roof has wooden shingles, take extra care to not loosen any of the tiles as you brush. You can also use moss removal products by spraying the roof surface to kill the remaining growth and prevent it from returning.

For that hard-to-remove debris, you can use a pressure washer. Keep it on a low setting (max. 100 bar) and spray towards the drainage channels on flat roofs, or from top to bottom on pitched roofs to stop water from accidentally entering the building.

Moss thrives in low light conditions. If your home is located near a tree, we recommend removing any branches that shade the roof. This also prevents the branches from falling on the roof during thunderstorms.

Check for surface damage

Roof damage can occur from a variety of sources. Gusting wind can cause the tiles to break loose, hailstorms can create holes, rapid temperature changes can cause cracks, etc. Whilst modern roofing membranes and tiles are capable of handling these challenges, older surfaces are more vulnerable to cracks and tears. Without proper treatment, these will worsen over time, which will also allow moisture to get inside and potentially causing even costlier repairs.


When assessing roof inspection, make sure that the tiles and/or membranes are all in place and intact. For flat roofs, blistering is a sign that moisture has penetrated the membrane which needs to be addressed before more problems occur. For pitched roofs, look out for chipped, broken or loose tiles, or any deformation from excess heat. Remember, it’s always better (and cheaper) to fix these minor problems before they get more serious.

Clear the gutters and drains

Branches, leaves, soil and other debris can often get washed into the drainage channels, which will lead to blockages forming (including trees taking root). On pitched roofs, this can cause water to pour over the side of the gutter and – with the added weight – potentially cause the drains to tear loose from their fixings.


This is a rather serious issue for flat roofs. If water cannot drain, it will begin to pool on the surface. If not dealt in time, the water weight may cause the surface to deflect, leading to even worse ponding and potentially serious structural issues. It can also allow algae to grow and create an unhealthy environment.


In most cases, you can scoop the debris by hand, but it may also be necessary to unblock the downpipe. Alternatively, you can run a length of wire down the downpipe/drainage channel to pierce a hole in the blockage and wash it out using a hose.

Look inside

Not all roof problems can be assessed from the outside as some may not be apparent. Which is why it is always a good idea to check the roof from beneath as well.
If you have a flat roof or a finished room within a pitched roof, look out for patches of damp or bubbling paint or wallpaper. This indicates that moisture is getting through the surface. Keep in mind that the location of the leak may be different from where the moisture shows up on the inner face, particularly for pitched roofs.
If you have an unconverted attic space, make sure that the ventilation channels are not being blocked around the eaves of the roof. Also, look out for warning signs such as damp timber or clear daylight being visible through the roof construction.
