Introduction
When it comes to installing or replacing your roof, the amount of information on the internet can sometimes be overwhelming. You will find a lot of information, websites, and video tutorials on how to install asphalt shingle roofs, but you can easily be confused by the great amount of material available. To help you with your asphalt shingle roof installation in Woodinville Washington, this article will walk you through the most basic steps and all the basic knowledge you need. So, without further ado, let’s get started.
Starter Course requirements for asphalt shingles roofs
Each roof has to start somewhere, and that spot is on the appropriately named starting tile, also known as the starting strip or starting course. A starter course should not be confused with 3-legged shingles or architectural shingles.
Install starter shingles
Starter shingles are the starter for strips/rows of shingles installed on the roof, just before the first row of trim shingles, which will be the visible parts of the roof. After securing the drip edge to the eave of a roof and laying the subfloor over the drip edge, you can install the starter layer along the eave / outside edge of the roof. The starter/course strip is made of the same material as any other fiberglass reinforced asphalt shingle. It is not imperative to install the starter layers along with the rakes, but it is smart because beginners harden the edges of the protruding shingles and create a sharper line of sight from below.
The tools you will need for installing asphalt shingles are:
- Air compressor
- Air hose
- Caulking gun
- Chalk line
- circular saw
- Hammer
- Measuring tape
- Utility knife
- Extension ladder
- Roof harness
- roofing nailer
- scaffold
- Stapler
- To reign
- Shears
Underlayment on standard slopes where asphalt roof shingles are installed
Subfloors temporarily protect the wood deck from moisture penetration until the shingles are applied, greatly reducing problems that could arise when the shingles are installed directly over a wet surface.
Stick the bottom part of the underlayment to the roof of the house
Low slope application requires a double-ply felt underlayment, cemented together, at a distance extending from the eaves to a point twenty-four inches in line with the interior wall of the building. Asphalt saturated felt along the eaves, overlapping successive nineteen-inch courses. End vertical overlaps should be at least 3 inches and horizontal overlaps six inches. If the shingle roof is going up with a steeper slope, extend the membrane twelve to eighteen inches to the slope of the main roof.
Install The Drip Edge
The drip edge serves as a cover for this roof vent air intake. It doesn’t completely block out the space. But it covers it enough that the elements don’t get in. To install the drip edge, slide the wide, flat collar of material under the first row of roof shingles as shown. Place the drip edge down, aligning it so that water drains into the gutters. The end with the flare should point down and away from the roof. Make sure the outside edge protrudes from the gutter.
Else, lightly pull the drip edge under the shingles. The actual drip edge should be carefully formed at a forty-five-degree angle to allow a clear overhang above the gutter. A pre-bent lip will further ensure that water drains directly into the gutter. If necessary, secure the ends of the drip edge with short roofing nails, just make sure they are properly seated under the shingles.
Remove old shingles
Before you get started, get a building permit and check local building codes. Removing old shingles is a hectic job and the best idea is to call roof repair service in Woodinville Washington. Keep the time between cutting and readjusting to a minimum and wait until the weather is clear. Doing a little ground prep work will keep nails and other debris out of your lawn and flower beds, reduce cleanup time, and preserve the landscape. Start the cut in the section furthest from the dumpster. Standing at the top, use a garden fork or a special notched shovel to remove the ridges and top rows of shingles.

You can expect to shell out $ 1.50 to $ 5.50 per square foot or $ 150 to $ 550 per square installed in a standard-sized one-story home. Obtain local costs below from contractors in your area.
Fixer Location Requirements for Asphalt Shingle Roofs
- Install an adhesive, peelable, and glued membrane over the entire roof decking, the 15th most recommended break in the felt bond between the membrane and the shingles.
- Apply roof covering flashing tape with a nominal width of 4 inches to all joints of the roof covering panels and cover with # 30 felt or equivalent synthetic base.
- Install a # 30 two-ply felt underlayment system.
- Place a drip edge over the gutters and rakes.
- Flash roof penetrations and roof wall intersections, properly integrated with sub-floor and roof and wall sheathing.
Steep Slope Limits & Shingle Nailing and Hand Seal
Use of staples for laying asphalt shingles. Asphalt roof shingle row offset requirements. Low and steep slope limits for asphalt shingles. Asphalt shingle roofing with flashing eaves and skylights. Best practices for installing roofing, flashing, ventilation, nailing, sub-flooring. The starter strip is positioned to overlap the eaves and rake edges and the drip edge that should already have been placed one by four to three by four inches. Do not overlap more than that or the edges of unsupported shingles are likely to bend and break over time.
Underlay Requirements For Asphalt Roof Shingles
Primer is not 100% necessary under asphalt shingles. At least not in unregulated areas. Building codes can also vary from area to area, and most building codes require a felt or synthetic roofing underlayment. If you are working in an area where building codes apply then yes, a tile underlay will almost certainly be needed.
Application of asphalt shingles on low slope roofs
Roof shingles can still be installed on a low slope roofing, as long as the minimum roofing slope for the shingles meets the requirements. For a roofer to properly install most types of shingles on a roof, the roof must have a minimum slope of two by twelve. It would be a slope with an angle of about 9 degrees parallel to the ground.
