Waterproofing flat roof

Waterproofing flat roof

Introduction

The property gets a full blast of sunshine daily which means that membranes and paint
covering will deteriorate faster than roofs that get a little shade from trees and will need roof
repairs. A flat roof has a very low angle of descent and if not sealed properly the damage that
may occur can be huge. Needless to say that it will cost a substantial amount of money.

Description of the condition of the property

This flat roof went on not getting the proper care for years. Luckily, not all roof screws came
loose and thus minimal water damage occurred.

Problem/situation

Here we have a case where waterproofing for this flat roof was urgently needed. The property
gets a full blast of sunshine daily which means that membranes and paint covering will
deteriorate faster than roofs that get a little shade from trees. The roof’s previous membrane
was cracked and showed signs of water seeping in. Being a flat roof, dust accumulated on
top of it and together with rain damp will form on the roof causing a lot of damage. The
exterior walls show signs of weather and moisture damage.

Possible outcome

As time goes by a roof that gathers moisture will start to rust away which means the roof will
fail to keep the weather out. As can be seen on the exterior walls, mould will grow and
compromise the health of all that stay within.

Suggestion to remedy the situation

It was suggested that the roof must be cleaned properly and all loose fasteners are replaced.
Then the roof can be waterproofed and painted. Exterior walls also need damp proofing and
paint.

Decision with customer/owner 

The owner opted to have the roof fixed first. He will, as finances allow, at a later date attend
to the waterproofing and painting of walls.

Work which was done 

Cleaning of the roof involved the blasting of dust particles off the roof with a high power hose.
Inspection on the fasteners and replacement where necessary followed. Only then was it
possible to waterproof flashing, fasteners and plumbers vents. A few coats of UV resistant
paint sealed the roof properly to protect it from the weather.
