How to Find Replace Your Asphalt Roof
Before getting into the nitty gritty of how you replace it, you need to know when replacement makes sense to begin with.
Some typical caution signs St. Petersburg homeowners notice are:
Missing or Curling Shingles
Curled or cracked shingles usually mean you have aging materials. Wearables get speedier in heat – Florida faster than most homeowners expect
Frequent Leaks
One leak can result in only necessary fixes. If there are leaks in multiple parts of the facility, the roof system is often going to be at fault.
Granules in Gutters
Granule loss with asphalt shingles is normal. If your gutters regularly catch ample amounts, the shingles are almost gone.
Sagging Roof Areas
That could be a sign that water is leaking under the shingles. That is something you need to take care of as soon as possible.
Roof Age
Asphalt roofs are typically designed to last anywhere between 15–30 years, depending on the quality of materials use and maintenance. Heat and storms typically also mean shorter lifespans in Florida.
Step By Step Guide To Replacing An Asphalt Roof
This understanding of how to replace asphalt roof systems will greatly benefit you as a homeowner when hiring professionals.
No beating around the bushes — this is a multi-step, serious construction project.
Step 1: Getting an estimate of the roof inspection
This starts with a comprehensive inspection.
Professional roofing contractors evaluate:
- Roof size
- Existing damage
- Ventilation
- Decking condition
- Flashing issues
- Structural concerns
Old Time Roofing prepares comprehensive estimates so that homeowners know exactly what is being replaced and why.
Step 2: Obtain Permits
Roofing permits are typically required in St. Petersburg and all of Pinellas County.
More than u realize this matters.
On the other hand, performing unpermitted roofing work creates complications during a future home sale or insurance claim. Permits are usually obtained through a professional contractor so that everything is up to Florida building codes.
Step 3: Getting rid of Old Roofing
Next comes the tear-off phase.
Roofers remove:
- Existing shingles
- Old underlayment
- Damaged flashing
- Roofing nails and debris
This exposes the roof decking underneath.
Some homeowners may ask, “Is it alright to put shingles over existing shingles?” Legally speaking, it may be permissible on the court side but in Florida climates sometimes and almost never long-term.
Stage 4: Inspect and Repair Roof Decking
The decking is inspected for once it has been exposed to elements:
- Rot
- Moisture damage
- Soft spots
- Structural weakness
Corroded wood needs to be replaced before new roofing materials can go on.
One of the biggest mistakes that inexperienced installers make is skipping this step.
Step 5: Underlayment and Waterproof Barriers
Florida Roofing Systems Need Strong Moisture Protection
Roofers install:
- Synthetic underlayment
- Water and ice barriers (in the vulnerable areas)
- Drip edges
- Flashing around penetrations
This layer helps to shield the foam from leaking in storms and wind-driven rain.
Step 6: Install Asphalt Shingles
This is part of the project in a visible manner now.
Install shingles in rows that overlap each other with correct nailing patterns and spacing. During this phase, ventilation systems and ridge caps as well.
In hurricane-prone St. Petersburg, proper installation is critical.
Installation quality plays a large role in longevity, and even seemingly premium shingles can fail very early.
Step 7: Final Clean Up and Check
Once the job is finished, contractors thoroughly tidy with the home and carry out concluding examinations.
Magnetic tools are also used by reputable roofing companies to pick-up nails from yards and driveways.
That last quality check is meant to confirm that the roof complies with local codes and meets the requirements of manufacturer warranties.
Average Asphalt Roof Replacement Costs
Cost is one of the main homeowner questions.
This is a very realistic example for St. Petersburg properties
Roof Size
Average Cost Range
Small Home
$7,000–$10,000
Medium Home
$10,000–$15,000
Large Home
$15,000–$18,000+
These numbers vary depending on:
- Roofing material quality
- Roof pitch
- Decking repairs
- Labor
- Ventilation upgrades
- Permit fees
Factors That Influence Roof Replacement Rates
Roofing Material Quality
Architectural shingles are more expensive than simple 3-tab shingles but typically last longer and hold up better against the wind.
Roof Complexity
Roofs or homes with more angles involve greater labor and safety precautions on the range of personnel who would be required to do the job.
Decking Damage
The cost of replacing rotten wood can add up in a hurry.
Ventilation Upgrades
Improper ventilation in your attic will shorten the lifespan of your roof. Many replacements include ventilation improvements.
Hurricane Requirements
You are using Florida code, which can bring labor and material costs up compared to other states.
To Repair or to Replace — Which Makes More Sense?
Sometimes repairs are enough.
Other times replacing pays off better. It won’t be long term money.
A simple approach to think about it is:
Repairs may be better if:
- Damage is isolated
- Roof is relatively new
- Leaks are minor
- Shingles are mostly intact
You would make more sense to replace if:
- Roof is over 20 years old
- Multiple leaks exist
- Storm damage is widespread
- Repairs are becoming frequent
This is where experienced contractors such as the guys at Old Time Roofing really shine. Of course, conducting a thorough inspection helps to keep homeowners from going overboard while also ensuring proper protection against damage.

Insurance Considerations for Roof Replacement
You have to understand that insurance is a big part of roofing in Florida.
Here’s what homeowners should know.
Storm Damage Claims
Insurance may cover some of that replacement if storms caused damage.
Age Restrictions
Few insurance companies limit coverage on aging roofs.
Proper Documentation Matters
Don’t assess damage without the help of professional contractors who know how to document correctly for your insurance claim.
Building Code Upgrades
The 25% rule in Florida also creates additional code requirements on repairs or replacements.
You can imagine how crucial professional guidance comes into play here.
Choosing The Right Roofing Contractor
It’s more important than the shingles themselves.
A well-installed roof will never fail even though the best materials are used.
Look for Licensing and Insurance
