You may already be familiar with the scenario: you go outside, look up at your home, and start to notice discoloration on your shingle roof. 

What now? 

Does this mean you need to start planning for a complete roof replacement?

A well-maintained roof is vital to a home’s protection and can add value when it comes time to sell. 

But what happens when your roof starts to show signs of aging or needs replacement? 

If you live in an area that sees a lot of bad weather, then sooner rather than later might be the answer. 

So, what are some things to look for, and how does the shingle roof replacement process work? 

Let’s take a closer look.

The Warning Signs You Need Roof Replacement

While widespread moss can undoubtedly harm your shingles over time, it’s not as detrimental as other issues. 

Roofing experts, including our technicians at Eagle Watch Roofing, will inform you that discoloration from a bit of moss or algae is only sometimes a clear sign you need a new shingle roof.

When it comes to your roof, the earlier you catch problems, the better. 

Here are some warning signs that you may need to replace your shingle roof:

Shingle Roof Replacement

Shingle condition

If from the ground (you should never climb on top of your roof), you begin to notice shingle edges that are curled up, tabs that have become cup-shaped, dislodged shingles, cracks, or missing pieces, this may be a sign that you need a roof replacement.

Granule loss

Check your gutters. See a lot of granules? It might be time for a shingle roof replacement.

If it’s possible to inspect your gutters safely via an extension ladder, you should pay attention to how much of your roof is in the gutter.

A large amount of granule loss almost always means your shingles have lost their water resistance. You can also inspect for bald spots on your roof.

If you start seeing granules on the ground around your home after a rainstorm, then this means that your shingles are likely getting worn out. 


Most, if not all, fiberglass-asphalt shingles are explicitly designed for twenty years of use; if your home’s roof is more than two decades old, contact Eagle Watch Roofing for a professional roof inspection and prognosis. 

The average lifespan of an asphalt shingle roof is about 20 years – if yours has reached and exceeded that mark, it’s probably time for a new one. 


A general tired, worn look, a faded color, or a shingle color that appears outdated can all be strong reasons to consider roof replacement.

The Process of Shingle Roof Replacement

Once you contact your local roofing professional to arrange a new shingle roof for your home, a representative should be sent out to both inspect and estimate the roof itself.

Factors such as roof pitch (its relative steepness), square footage, and accessibility will affect how long the replacement job will take.

Typical steps

Though each job site differs, the steps for roof replacement are roughly the same for every quality roofing company. 

They should include:

  1. Protecting your landscaping and plants
  2. Tearing off the roof’s old shingles
  3. Inspecting the old sheathing and replacing sections as needed while ensuring proper nailing throughout
  4. Cutting sheathing for roof vents if needed
  5. Installing drip edge (which helps divert water away from your roof)
  6. Installing ice and water shield
  7. Installing self-adhesive underlayment or roofing felt
  8. Installing new fiberglass-asphalt shingles
  9. Site cleanup
  10. Final job inspection


Replacing shingle roofs can be complex – trust only some people! 

Make sure you hire a local roofer with the experience to do the job right.

Ask for references and look at past projects to ensure they can handle your needs.
