Common weak points on a flat roof are around the edges and abutment points. Roof coverings where allowances have not been made for structural movement are possible sources of leaks as well as defective flashings and pointing.
Sometimes the defects on a flat roof are so extensive or severe that the roof needs replacing. If this is the case we’ll provide you with a detailed assessment of the findings and a fixed price quote to get the work completed.
If repair work isn’t carried out quickly the damage caused by water can dramatically increase repair costs. Structural timbers can be weakened if they’re continually holding water. Saturated brickwork and masonry can cause internal damp problems that can result in the need for extensive internal decoration work.
A Nottingham roofer will check your flat roof thoroughly when called for repair work. If necessary, they will try to stop any further damage from taking place before continuing with their repairs.
Problems With Flat Roofs
Leaks and moisture – Probably the most common problems with flat roofs, leaks and lingering moisture are issues that can be dealt with effectively, as long as you stay on top of them. Just like any roof, a flat roof will develop leaks, but since it's flat, the water doesn't have anywhere to go but straight down
Are flat roofs a bad idea?
Flat roofs generally require a greater degree of maintenance – even more so if the surface is disturbed and damaged by people frequently walking over it. Flat roof drainage is historically not as effective as traditional pitched roofs and standing water (ponding) can be an issue if falls are not adequate.
Why are flat roofs so expensive?
Flat roofs are cheaper to install because they need fewer materials. There is the reduced cost of not using rafters etc. which are needed for pitched roofs, as well as the greatly reduced time taken to install them. The cost of the materials themselves is a lot less than the materials needed for a pitched roof.
What is the disadvantage of low slope roofs
Low slope roofs change how water flows off of the structure. High pitched roofs don't let water sit, so asphalt shingles and other materials that overlap work well. On a roof with a lower pitch, standing water soaks between these materials.
What's the best flat roof system?
Ethylene Polypropylene Diene Monomer (EPDM) is one of the most versatile rubber roofing options on the market. Considered to be one of the best materials for flat roofs, rubber is a popular choice for industrial and commercial applications thanks to its ability to withstand extreme weather conditions
