Navigating Warranty Complications in Brunswick: Does Installing Metal Over Shingles Void Your Warranty?

 

In the world of roofing in Brunswick, Georgia, the issue of warranties often poses a puzzle for homeowners. The pivotal question is: will installing a metal roof over shingles nullify your warranty? The answer is typical, 'It depends'.

Are you covered after the work is done

Different manufacturers adopt varied positions on this matter. Some may consider their warranty void if their metal roofing materials are overlaid on shingles. While others may not have any specific provision for this scenario in their warranty terms.

So, how can you, as a Brunswick homeowner, navigate this complex landscape? The most straightforward path is open communication. Reach out to your metal roofing material provider and inquire about their warranty rules. Check whether the removal of old shingles is necessary to uphold the warranty.

Remember, in the coastal environment of Brunswick, with its unique climatic conditions, it's better to play it safe. Do your due diligence before deciding to install a metal roof over existing shingles. Make sure your warranty will stand and your installation is in line with all local building codes. No one wants unwelcome surprises after the roofing project is installed.

Uncovering the Truth: Why Brunswick Experts Advise Against Installing a Metal Roof Over Shingles

 

Wondering why metal roofing experts are skeptical about installing a metal roof over shingles? Let's dive into the heart of the matter. Consider the following analogy.

You approach a doctor with a headache, but instead of diagnosing the underlying issue, they stick a band-aid on your forehead. This is akin to installing a metal roof over shingles. 

It's hard to learn the true health of the underlying plywood without stripping off the old shingles. And who wants to deal with that headache in the balmy Brunswick climate? Certain red flags can suggest trouble with your plywood. By the end of this section, you'll have the tools to check your roof like a pro!

Watch out for these 4 warning signs:

  1. Sagging or uneven roof: If the roof appears uneven or sagging, it could be a telltale sign of rotting or water-damaged plywood underneath.
  2. Visible water damage: Any visible water stains or discoloration on the underside of the roof or the ceilings in the attic suggest a leaky roof. This could mean water has penetrated and possibly damaged the plywood.
  3. Soft or spongy roof: If the roof feels soft or gives way underfoot, it's a sign of rotting plywood.
  4. Obvious signs of rot: Dark, discolored, or moldy patches on the roof's plywood are clear signs of decay.

Remember, some of these symptoms might not show until the metal roofing is in place. An experienced Brunswick metal roofer understands this. The integrity of a new metal roof depends on the condition of the underlayment and wood decking. This is why most will refrain from overlaying a new metal roof over shingles.

Calculating the Real Costs: Does Installing a Metal Roof Over Old Shingles Save Money in Brunswick?

 

In the sunny city of Brunswick, Georgia, you might be wondering if installing a metal roof over old shingles will save you some hard-earned bucks. Well, the answer isn't as straightforward as you might think!

Imagine you have a pair of jeans with a tear. A patch might seem like a quick and cheap solution, but as time goes by, the rip may get bigger, and eventually, you'll have to replace the jeans entirely. The same logic applies to overlaying a metal roof on old shingles. It might look like a cost-effective strategy at first, but it could lead to costly repairs later on.

Plus, consider the expenses associated with disposing of your old shingles. The average cost to remove and dispose of old shingles ranges between $1,000 and $1,600, a price tag you might want to bear in mind.
