Common flat roof issues
Ponding water
Flat roofing often suffers from poor drainage, leading to the accumulation of stagnant water. Prolonged standing water can degrade the roofing membrane, resulting in potential leaks and structural damage.
Blistering
Trapped air or moisture beneath or between layers of the roofing membrane can cause blistering. When exposed to heat from the sun, these blisters expand, stretching and damaging the membrane.
Buckling in membrane
Over time, natural settling and movement of the building can cause the roofing membrane to buckle. This movement is especially noticeable since flat roof membranes usually consist of a single sheet.
Alligatoring
Alligatoring refers to the cracking pattern resembling an alligator’s hide on the surface coating or bitumen of a flat roof. This can occur due to factors like water damage, debris accumulation, or prolonged sun exposure. Untreated cracks can worsen, leading to further water intrusion and structural issues.
Thermal movement
Temperature fluctuations cause the roofing materials to expand and contract. However, excessive thermal movement can weaken the roof, potentially resulting in leaks. It can also affect the flashing, causing it to separate from the roof edges and create entry points for water.
EPDM roofs
When it comes to protecting flat roofs on house extensions, garages, sheds, and smaller buildings, traditional materials like asphalt, felt, or bitumen have been commonly used. However, there is a new, innovative solution taking the industry by storm: EPDM rubber.
EPDM rubber is rapidly gaining popularity as the ideal choice for flat roof repairs among homeowners and industry experts alike. This cost-effective and lightweight material offers a wide range of benefits, making it a preferred option for London homeowners. Its durability, water resistance, and numerous other advantages make it a smart investment that saves both time and money.
