What is a flashing?
Let's run over a few factors that will influence roof repair costs.
Accessibility
Obviously if you live on the top of a mountain which is only accessible by helicopter
you are going to be paying more, even if it is just a small job...
The pitch of the covering also weighs heavy with pricing. The higher the pitch
(slope) of a covering the slower the crew will be working to take the necessary
safety precautions.
The use of scaffolding or rope access will further drive up expenses and in some
cases the price to arrange access to the problem area will far outweigh the actual
price of doing the repair!
Type of roofing material
If the covering is really old it may be hard to come by replacement materials.
Slate tiles
Some slate tiles have a waterproofing underlay. If this underlay is damaged or
deteriorated beyond repair it may need to be replaced.
Often it may not be possible to only fix a section of this underlay and an entire
elevation may need to be done.
Asbestos
Old asbestos materials are by law required to be disposed of if removed,even
briefly, during a project. The contractor will not be able to refit asbestos products to
the structure and new fibre-cement replacements will need to be fitted.
Breakages may occur will working on the covering for which the contractor will not
be liable. Depending on the condition of the covering, this could tally up to a sizable
amount.
Steel Coverings
Steel, if rusted should be replaced not repaired. Fitting new steel alongside rusted
steel is like putting good apples with bad ones. Most reputable contractors will only
quote to replace entire sections if the covering has started rusting.
Flat decks and Torch On
On flat decks, Torch on, Derbigum and the like, are easy enough to patch if you know
exactly where the water is getting in. But if this is not the case (which it usually is) the
one is just taking a shot in the dark by patching. Most reputable contractors will want
to isolate an entire area, strip it all up and do it over.
Balconies
Balconies that are covered with tiles or cement screed will need to be stripped up in
their entirety and all the waterproofing be redone.
There are of course numerous products you may wish to try before going that route,
but we advise, as with all products, first do research and get other peoples opinions
on the product.
