To replace a roof that is rolled roofing, you need to remove the old material, inspect the deck, and install new rolled roofing in layers. Rolled roofing is a budget choice for flat or low-slope roofs. It lasts about 10 to 15 years on average. Many homeowners pick rolled roofing because it costs less than other options. According to RubyHome, the average roof replacement cost is $9,526, with a range of $5,868 to $13,217. This guide shows you how to do it right.

What Is Rolled Roofing?

Rolled roofing is a thin, flexible material made of asphalt and fiber. It comes in big rolls that you unroll and nail down. Each layer overlaps the one below it.

This type of roof works best on flat roofs or roofs with a very gentle slope. It is not right for steep roofs. Rolled roofing is one of the cheapest roof choices you can buy.

How Long Does Rolled Roofing Last?

Rolled roofing typically lasts between 10 and 15 years. Some can last up to 20 years with good care. This is much shorter than other roof types.

According to industry data, asphalt-based roofing systems have lifespans ranging from 20 to 30 years, but rolled roofing falls on the lower end. Metal roofing lasts 40 to 80 years, and concrete tiles last 100+ years. If you want a roof that lasts longer, consider upgrading to a different material.

Steps to Replace Rolled Roofing

Start by taking off the old roofing. Use a shovel or pry bar to lift the old material. Remove all nails and clean the deck. Look for soft spots or damage to the wood.

Next, lay down a new base layer of rolled roofing. Roll it out and nail it every 12 inches along the edges. Then add a second layer on top, overlapping by 6 inches. Seal all seams with roofing cement. Nail the top layer every 12 to 16 inches. Use short roofing nails to hold it in place.

Cost and Labor

The cost depends on your roof size and where you live. According to RubyHome, roof installation costs range from $4 to $40 per square foot. For a 1,700 square foot roof, expect $6,800 to $68,000 in total cost, though most rolled roofing jobs cost much less.

Hiring a pro costs more but ensures quality work. According to the U.S. Bureau of Labor Statistics, the median annual wage for roofers is $50,030. DIY can save money but risks mistakes that lead to leaks and higher long-term costs.
