Do you need a roof replacement? This is a major investment of time and money for most homeowners. And the best way to ensure you use your money wisely is to understand what's involved in a roof replacement. Here are the major steps your contractor will undertake.

1. Take Off Old Materials

Most full replacements start with the removal of all the old shingles. In general, you must replace the shingles because these are the most susceptible to weather and sun exposure. The contractor will dispose of shingles, usually calling for a dumpster to keep things neat. 

2. Fix Base Layers

Once the shingles (or tile) are gone, the roofer will inspect and analyze the number of repairs needed to the base structure. They may fix or repair underlayment or flashing if possible. If not, these are removed as well. They will make any necessary repairs to the wood sheathing. 

3. Install Water Shields

Ice and water shields are protective barriers, usually along the edges of the roof, to prevent moisture from getting to the lower part of the roof's structure. Some areas require special barriers, but many homeowners opt for them regardless of local law. 

4. Lay Underlayment

The underlayment is a water-resistant barrier to protect the wood underneath. It's usually rolled out in long sheets which are secured to the sheathing. Most old underlayment is made from felt treated with asphalt products, but you have more ecologically friendly materials to choose from today. 

5. Add Flashing

The flashing generally comes next. Usually made from steel or copper, flashing is an additional barrier against moisture, including rain, ice, and snow. The roofer may install flashing where there are joints in the roof or where anything protrudes (such as a skylight or chimney). 

6. Install Shingles

Finally, it's time for the shingles to be applied. The roofers will install shingles in an overlapping pattern to help reduce the chance of moisture getting underneath any. Today's homeowners have a range of shingle choices in terms of color, texture, cooling technology, or waterproof features. 

7. Clean Up

A good-quality roofing company will also clean up after itself. You can expect them to clean up excess materials, remove potentially dangerous debris, and help restore anything that they had to move in order to work.
