Residential Roofing: Tackling Shingle Roof Installation The Right Way

Whether your shingle roof has been damaged by weather or simply aged to the point where it’s just deteriorated beyond repair, it will eventually need to be replaced.

Installing a new roof is a serious undertaking, and one that very few homeowners will (or should!) tackle themselves. Because of the critical role your roof plays in protecting your home, this is a job that’s best left to your local roofing contractor experienced with the ins and outs of the roofing replacement process.

If you’ve never gone through re-roofing, it may seem a bit overwhelming and you may not know where to start.  But, no worries. Whether you’re a novice or a seasoned homeowners, we’ll show you what the steps to tackling shingle roof installation the right way!

Residential Roofing: Shingle Roof Installation The Right Way

Tackling Shingle Roofing Installation The Right Way

Installing a new shingle roof is a huge commitment, so understanding the entire re-roofing process from start to finish can be highly beneficial to you as a homeowner. From questions about the cost involved to knowing the installation pitfalls to watch out for, there’s a lot of information that you need to familiarize yourself with if you want a successful replacement with no costly surprises along the way.

1. Selecting a contractor and getting an estimate

The most important part is researching and selecting the right roofing contractor for your replacement. When choosing a roofer, be sure to select an experienced, licensed, and insured company that’s local to your area. Pick few contractors and collect multiple estimates you can compare.

Remember, while total project cost is an important consideration, it’s certainly not the only thing you need to keep in mind. In fact, many homeowners make the mistake of going with a particular contractor simply because they’re the cheapest, only to learn later that shoddy workmanship and inferior materials led to unsatisfactory results.

All quality roofing estimates should include:

  • Estimated project duration
  • Detailed description of work, including roofing materials, flashing locations & underlayment type
  • Type of sealant used to weatherproof flashing and nail holes
  • Cleanup expectations
  • Total project cost:
    • Building material costs (roofing material, fasteners, flashing)
    • Labor costs, broken down by man hours or listed as a project bid
    • Additional expenses, such as sheathing repairs, tear-out of old shingles, etc.

2. Inspecting and replacing underlying materials

Roofing replacement will start differently, depending whether you’re tearing off the old shingles or adding a top layer of new shingles to the existing roof. Most likely, however, your contractor will remove old shingles and underlying roofing materials completely in order to inspect wood decking. Any soft or rotted wood decking will be removed and replaced as well – this will provide a solid base for your new shingles.

Next, drip edge will then be installed at all edges of the roof. Drip edge prevents rain and snow from getting underneath your shingles around the roof’s perimeter.

Finally, your roofer will install “ice and water shield” which is a special type of roofing underlayment. This is installed at the bottom few feet of the roof and around all roof penetrations, such as chimneys and pipes. Prior to installing the shingles, the remainder of the roof is covered with roofing felt (sometimes called “tar paper”), which prevents shingles from sticking to the wood & offers additional protection.

At this point, the roof is ready for new layer of shingles to be installed.

3. Installing new shingles and final inspection

Working from the bottom of the roof toward the top, the roofing crew will install your choice of asphalt shingles.

The two most important things to look for in a quality asphalt shingle are its performance characteristics and its warranty. To get the most for your money, make sure that you consider life span, durability, weather resistance and quality when you select your new roof shingles, not just the price tag. Choose roofing shingles with a lengthy, comprehensive manufacturer’s warranty since high-quality shingles come with warranties of up to 25 years or more. Also, look for roof shingles that complement your siding or brick.

After shingles are laid out, step and/or counter flashing, ridge vents, and ridge capping installation follows. A thorough clean up of the job site is next, while any old roofing materials are hauled away. On that note: many homeowners choose to recycle old asphalt shingles rather than send them to a landfill, so if your contractor offers that option, be sure to consider it.

Every roofing replacement process should end with a thorough post-installation roof inspection!

Have Your Roofing Installed Right, The First Time!

One additional aspect of roofing installation is warranty information – material, system, and workmanship warranties come in many flavors. This is critical and often overlooked factor – ensure that you’re adequately protected for years to come by selecting wisely.

Educate yourself on proper installation to make the best investment possible.

    My wife and I are wanting to get our roof fixed up before it starts snowing here, but we aren’t sure where to start. I like that you mention asking for things like build material and cleanup costs in the written estimate. I want to know exactly what I am paying before they start work, so I’ll be sure to do this. Thanks for sharing!
