Roof Installation

2. Evaluate the Roof

After removing the old roof, evaluate the sheathing. Roof sheathing is made up of flat panels that provide structural support and a base on which roofing materials, like shingles, are attached. Look for any moist areas or trouble spots that will have to be replaced.

You may have heard the term decking, that means the sheathing on the entire roof was removed and replaced or re-decked. This is extremely expensive, especially with wood prices where they are at now re-decking your entire home will cost you dearly.

When you look for areas that are moist or soft to the step, these for sure must be replaced.

Other reasons to replace the sheathing is if your roof has not been done in the past 10 years or more, there may be pieces of sheathing with cracks and or holes due to rusty nails that have dug themselves out.

Consider changing these out as well. It is hard to say what the condition of the but sheathing will be, it may be in good shape if you are lucky but sometimes the entire roof may have massive issues that will come to light only after you have removed the first layer – there is just no other way to put it, some homeowners are lucky and others not so much.

If you have a wood shake shingle roof you will always have to re-deck since wood shake shingles were installed on spaced out decking and are no longer legal in California.

If you remove the wood shake shingles you will be able to see straight into your house because wood shake shingles were not installed on top of a solid flat panel.

3. Protect Against Ice

If you live in an area that’s prone to ice for even part of the year, it’s important to install an ice and water barrier around your roof. GreenLiving installs the Owens Corning 7 layer roof so you get a waterproofing layer called weatherlock installed either way.

The product should go on around the edges of the roof, but especially at the very bottom edge that is most prone to the buildup of water or ice.

This sticky underlayment adheres to the roof sheathing, then nailed down for added strength and stability with roofing nails.

4. Put on the Drip Edge

The drip edge for the roofing goes down in two different parts of the roof installation. For the lower part of the roof it goes on before the underlayment, for the sides of the roof it goes on after. First, install the metal drip edge along the bottom edge of your home over top of the ice and water barrier. Nail it into place flat against the roof.

After you get the roof underlayment installed on your home you have to go over that with drip edge on the sides the same way that you did at the bottom. This prevents water from running over the edge of the siding and then back underneath it.

5. Roofing Underlayment Installation

Roof underlayment, whether felt paper or synthetic, is saturated in water resistant materials and comes in two thicknesses, 15# and 30#. The 30# underlayment is twice as durable as the 15#, but the synthetic products are much more durable than either felt paper option.

We use a synthetic underlayment that is rip proof and waterproof.

If you are looking for the most effective way to protect your roof besides for the roofing itself, invest in the more expensive synthetic underlayment, it’s the most convenient and durable option.

Roll the underlayment along the edge of the roof and secure it in place using cap roof nails every four inches along the outside edges and around eight inches in the center. These cap nails should not go through the drip edge, but instead just above it.

Roll out one row of roofing underlayment after another securing it all down with roofing cap nails making sure to overlap the lower row by at least six inches with the next row.

Overlap the underlayment sections up to the peak of the roof and then install a row straddling the peak so that the underlayment caps off both sides of the roof at the same time.

How to Install Asphalt Shingles

Asphalt shingles are known for being one of the simplest types of roofing materials to install.

First, lay a run of starter shingles along the bottom of the roof and nail them firmly into place using roofing nails a couple inches up from the edge of the roof.

Lay a row of starter shingles down both sides of the roof as well and secure those in place using roofing nails an inch or two away from the edge as well.

Lay out the first full shingle near the bottom corner of the roof and lock it into place using six nails all just below the tar line of the shingle.

Lay the next shingle down and nail it the exact same way. Continue this process until you’ve gone across the roof from one side to the other.

For each new row, stagger the roofing. Shingles have broken sections at the bottom and square sections. Line the square section of your next row up with the broken section of the previous row so the break is right in the middle of the square.

This gives water something to flow over so it isn’t leaking down behind your shingles. Lay out all the remaining shingles with the new staggered pattern, but use four nails per shingle this time.

On the next row of the shingles go back to the original position so that your shingles are lined up with the edge of the roof once again. This maintains the stagger and makes the roof stronger overall.

Repeat this process up to the cap of the roof on both sides until you are within five inches of the top.

To cap the roof you need a set of ridge cap shingles. Lay the first shingle on the left side of the roof so it’s overhanging the edge slightly and nail it down on the right side of the shingle to lock it in place.

Lay another piece down so it’s overlapping that right edge and covering the nail, and nail it in the same way. Continue this trend until you cover the ridge entirely. Put tar or roofing cement over the exposed nail on the end to finish your installation.

Other: Sealing Roof Vents and Pipes

Throughout the installation of the roofing, there will be pipes and vents that need to be sealed. These are usually sealed with a special rubber boot that simply slips over the protrusion.

In order to protect your roof and these vulnerable sections of the roof, protective rubber boots are slipped over top of the pipes and installed underneath the higher row of roofing when installing around shingles.

When installing on metal roofing, you seal under the flashing using a roofing cement and then fasten the flashing right over top of the metal roofing using rubber washer roofing screws just as you did with the roofing itself.

Now that you know what goes into the roof installation process for a basic asphalt shingle or metal roof, you can decide if you want to do the work yourself or to pay a roof contractor to take care of it for you instead.
