Restore or Replace Your Roof: What Should You Do?

Created on:

If you have roof problems, you have one of two choices to make: to either restore or replace it. These two terms are often confused for each other and used interchangeably, but they mean different things.

In this blog post, we'll examine the factors to consider that'll lead you to either restore or replace your roof.

What are roof restorations and roof replacements?

When your roof starts leaking or shows deterioration signs, you might just want to replace it completely. However, more often than not, all you need to do is to restore your roof to a better condition.

Roof restoration is the proactive measure used to extend the life of an existing roof. It refers to the cleaning, repair, and re-coating of a roof. Melbourne roof restorations are beneficial to many types of roofs, which include Terracotta tiles, galvanized iron, and concrete tiles.

On the other hand, roof replacement is the tearing off of everything down to the deck, and putting on new shingles, felt papers, flashings, and other roofing materials. Roof replacement shouldn't be confused with reroofing, which means laying another set of shingles over the existing ones.

Factors to consider when deciding whether to replace or restore your roof

To help you make an informed decision on whether you should replace or restore your roof, here are some factors you should keep in mind:

The age of your roof: This is perhaps the most crucial factor to consider when deciding on whether to replace or carry out repairs on your Melbourne roof. If the roof is not in good shape but was recently installed, then it makes more sense to restore it. However, for roofs that have existed past the 20-year mark, it'll better if you replaced it as a long-term option.

Location of leaks: Secondly, the number of cracks and roof leaks in your home will help you decide whether to replace or restore it. If the leak or crack is isolated and in only a few places, then it makes more sense to restore it. However, if you have several leaks and cracks all over your roof, then a roof replacement is in order.

The cost: Generally, roof restorations are a cost-effective option when working on your roof. Since it is considered a maintenance procedure, you'll also pay less tax when replacing your roof. On the other hand, replacing your roof will incur lots of labor and materials since it is considered a capital expense. There'll also be hidden costs like cost of change in gutters and landscape damages included when replacing your roof.

How long you intend to stay in your home: If you plan to sell off your home and your roof is in fairly good shape, it is recommended that you restore rather than replace it and vice versa. A replaced roof will likely last longer than a restored one, but restoration should be proactively maintained throughout the lifecycle of the roof.

The type of roofing material: Finally, the type of roofing material you have will determine whether you should replace it or restore it after a given time.

For example, a 50-year old roof made from slate might have quite some years ahead of it and so can be restored, whereas metal roofs almost always have to be replaced after a few years.

With these factors in mind, you can decide whether to replace or restore your roof. However, to be double sure on whether you've made the right decision, it is best you consult with a roofing professional. They'll inspect and assess your roof's situation so that you can make the right judgment call.

When should you not consider roof restorations?

You can decide to replace your roof at any time, without incurring some hidden problems later on. However, restorations are not recommended in some situations like:

Lack of adhesion on the seams

Retrofitted systems

Wet insulations

Excessive delimitation and blisters

Fastener back outs
