An Updated Roof Replacement Guide

By Stacy Mellete

Replacing your old roof is a good idea if you would like to avoid leaks and other problems. Before taking on the project, however, it’s best to prepare a budget. Here’s an updated pricing guide for roof replacement from Affordable Roofing Systems, your local roofing contractor in St. Petersburg FL.



The price of roof replacement in St. Petersburg FL varies, but usually, a contractor charges about $3.50 to $5.50 per sq. ft. or $350 to $550 per square (100 sq. ft. of roof surface) of architectural shingles installed. Roofs are typically in the vicinity of 1,700 square feet.

This costing includes adding and removing up to two layers of shingles, installation of underlayment and ice-and-water shield at the eaves and valleys of the roof, as well as the required building permit expenses.

Geographic Location

Another factor to consider in the pricing is the location of your house. Roof prices in the deep South are much lower (around $2.50 to 3.50 per sq. ft.) while costs are higher in the North East or the West Coast (around $5.00 to $7.50 per sq. ft.)

Choosing Your Contractor

A startup contractor may cost less than an established one and can charge less than $2.50 per sq. ft. or $250 per square. However, remember that not all inexpensive services are a good value. Contractors who use sub-contractors work on volume and at times, quality is compromised. It’s always better to trust a local roofing company with a good track record, like Affordable Roofing Systems.

Sample Breakdown of Expenses for Materials and Professional Installation:

1. 3-tab shingles – These are the most basic and cheapest kind of shingles. They cost $150 to $200 per square including all needed materials like roofing felt/underlayment, ice-and-water shield, nails, ride-vent and roof flashing details. The installation will cost approximately $350 to $450 per square foot or $6,725 to $9,000 for a U.S. ranch-type home and usually has a 5-year workmanship warranty.

2. 30-year architectural shingles – These are thicker compared to the 3-tab shingles and cost about $70 to $100 more. The installation price for a ranch style house can range from $7,850 to $11,000 considering the roof size and complexity, roofing company, quality of installation, warranty and location.

3. Premium shingles – Their average cost ranges from $450 to $750 per square installed, or $9,000 to $15,000 depending on the contractor, roof access, and home location. They usually have a 10-year workmanship warranty.
