Roof Flashing

Heritage Roofing Melbourne – Specialist Roof Leak Repair

The most common cause of a leaking roof is when a Roof Flashing is missing or damaged. A ‘flashing’ is a covering that is installed on the roof to prevent rain water from flowing through under the roof.

Entry points for water to leak through when not diverted are typically where the roof joins a wall, along roof valleys, and the perimeter around a chimney, vent or skylight. Nearly anywhere where the runoff is heavy or where two opposing surfaces meet, can be susceptible and hence requires the protection that flashings provide.

Steps we take when installing roof flashing

When installing roof flashing, Heritage Roofing Melbourne takes great care to protect the flashing from reacting with other roofing materials. For example, if a metal flashing comes into direct contact with a metal roof, corrosion can occur, causing rust and metal decay.

Flashings are nailed or stapled securely into place around the penetrations in the roof. All gaps are sealed with glue, caulk or waterproof cement.

If your flashing is made up of cement or tar, we recommend that it be tested, and ideally be replaced with a newer method of flashing.

Drip Edge Flashing

Drip edge flashing protects the bottom edges of the roof by the gutter, as well as the sides of the roof along a rake. It is a strip of metal attached to the roof deck that extends beyond an eave or rake. A drip edge flashing is designed to channel rain water away from the roof and the fascia.

Valley Flashing

A valley is where two sloping roof sections meet. A valley flashing is installed beneath the shingles on both sides of the valley to channel water flow. The best method to seal a valley is to fit a strip of roofing felt or a waterproof membrane before installing installing galvanised metal flashing.

Roof flashing repair cost

The cost of repairing roof flashings depend on the amount of labour involved and the materials to be used.

At Heritage Roofing Melbourne we prefer to use galvanised steel or aluminium flashing materials. Galvanised steel is a low-cost, durable and robust material. Aluminium is malleable, which allows it to be bent around odd shapes in a roof. Both types of flashing are low-maintenance and long-lasting.

Rubber and synthetic materials are a popular choice amongst our clients, as these are easier to install and are more cost effective.

Prior to commencing your job, we will discuss your options, and provide the associated costs so you can make an informed decision.

The three skylights on the roof had rusted flashing. The domes were polluted on the tops and undersides. The metal flashings holding the skylight domes to the bases of the skylights were badly rusted and needing replacement.The metal flashing between the slate roof face and the metal roof was faulty and leaking, with many siliconed and broken slate.

We removed the bottom two rows of slate between the slate roof and the metal roof, and salvaged any slate that were sound. We extended the existing flashing then re-slated in the bottom two rows of slate, replacing any cracked and broken slate with matching slate.The rusted metal trims holding the perspex domes to the skylight bases were removed and the domes were then removed and thoroughly cleaned on the tops and undersides. The domes were then re-secured with new metal flashings to hold them in place.

The base flashings of the three skylights were treated with industrial strength rust converter, then coated with a polyurethane waterproofing membrane.
