7 Signs You Need a Roof Replacement and What to Expect

Many homeowners forget to ensure their roofs function properly when maintaining their property. This is usually overlooked or left to the last minute because it can seem overwhelming to think about the roof repairs, costs, and processes. However, leaving a roof replacement to the last minute can contribute to more significant issues and costs further down the road. 

So, to avoid any future headaches, this blog will cover the signs that you need a roof replacement and what you should expect during the process. Read on to learn more about roof repairs and how the experts at Arthurs Roof and Property can help transform your Christchurch home with a brand-new roof. 

What is a Roof Replacement?

When it’s time for a roof replacement, this job is best left to the professionals. The process involves removing old or damaged roofing materials, and there will likely be roof repairs that will need to be done before a replacement is actioned. This is a crucial step, especially if your existing roof is severely damaged or worn out. 

This technical process requires a qualified team with industry knowledge and experience to complete it successfully and safely. While there may be visible signs that signal very clearly when you need a roof replacement, some signs aren’t as easy to spot. Below are seven indicators that a roof replacement is on the horizon, and if you notice any of these signs, it’s time to call in the experts. 

Ageing Out

Generally, most roofs have an average lifespan of 20 to 30 years, but this depends on the original roofing materials installed and the skill level of the installation team. If you have been living in your home for a few years, but maybe it was built a few decades ago, and the roof hasn’t been replaced or well-maintained, it may be time to consider a replacement. To ensure you don’t end up in an emergency situation, you should build a relationship with a reputable roofing company that offers inspections, repairs and maintenance. That way, you should get a good bit of notice that a hefty outlay is not far off.

Deteriorating Shingles 

Suppose you walk outside your property and spot missing shingles, especially in large numbers, or you can see from the ground that they are cracked and damaged. This clearly indicates that they are deteriorating and is a common sign that it’s time for roof repairs and replacement. You should never take a closer look yourself; call a team with all the right equipment to work at height - it’s just not worth the risk.

Accelerated Growth of Moss or Algae 

While this doesn’t always indicate you need your roof replaced, if moss or algae are left to build up over time, this can lead to serious problems. If you have noticed excessive growth or large amounts of moss and algae, leaving this issue unchecked can only cause further damage by trapping moisture in the roof surface, leading to faster deterioration. 

Visible Asphalt Granules

If your roof was installed using asphalt shingles, you may notice tiny granules falling into your spouting or onto the ground over time. These granules signal that the protective coating covering the asphalt shingles is starting to deteriorate, and the roof may be approaching the end of its lifespan. Call in a team that is trained to work at height as quickly as possible, as even one missing or broken shingle can escalate to structural damage if water makes its way into your property.

Leaks & Waterstains

If you notice a build-up of water stains or visible leaks on the ceilings and walls inside your home, this can indicate that your roof is failing. If you have caught these issues in time, repairing cracks, splits, corrosion, or deteriorating tiles may be possible. However, if these issues have been left to escalate, it may be time for a roof replacement.

Sagging Roof

Are you noticing a sagging or uneven roofline? Don’t delay taking action, as this is a crucial sign of serious underlying problems with your roof's support structure. Once the roof decking and the subroof structure begin to fail, it has serious implications, and roof replacement is likely necessary. 

Exposed Roof Deck 

When you notice signs of light coming through the roof decking, or you can spot any open gaps, it means your roof system is failing and needs replacement. The roof decking is an essential component of your roof system because it supports the roofing materials. If this begins to deteriorate, it’s time to act fast. 

What to expect during the roof repairs and replacement process.

Step 1: Consultation & Inspection 

Our team will schedule an initial inspection to assess your roof's current condition, which involves looking for signs of serious damage or other issues. After a thorough inspection, we will recommend the best approach to repairing or replacing your roof in a detailed proposal. 

Step 2: Quote & Proposal 

After our team has gathered and reviewed all the essential information, we will outline the required scope of work, including details about what materials need to be replaced on your roof. We will also provide you with a quote which outlines the cost of materials required and any additional services if necessary. 

Step 3: Contract and Timeline 

Once you are happy with the quote and proposal, we can sign the contract and move forward to set a timeline for the roof replacement project. Our team will plan the entire process and ensure as little disruption as possible. 

Step 4: Site Preparation

Our team will arrive at your property on the agreed-upon date and begin preparing the site and area to be worked on. Our work will be completed to a high standard, and we ensure proper preparation by laying down a tarp to ensure no rubbish or mess is left on your property. We’ll remove the existing and damaged roofing and dispose of these materials safely. 

Step 5: Installation and Final Inspection 

As outlined in the project's proposal, we will begin installing your new roof. This could involve decking repairs, underlayment, and new roofing materials. Once we have completed the required work, our team will also complete a final site inspection to ensure everything has been installed correctly and to a high standard. There’s no need to worry about clearing away any old materials, as we take care of this.
