A² Shingle Replacement

The A² 10-Step Shingle Roofing Process

Thank you for your visit and interest. We’d like to share A²’s 10-step shingle roofing process, - this way you’ll know what to expect. Our technitians are factory trained to follow the neccessary guidlines that meet all warranty requirements. The following steps are not just good ideas, they are a pre-requisite for many shingle manufacturers to honor your warranty.

Step 1 - A² Shingles Roofing Process: “Tear-Off Of Existing Roof Covering”

Stripping the old roof down to clean decking is important for a number of reasons. It exposes any weaknesses on the existing roof deck. For any new roof to function properly it needs to be installed on a solid base. Excessive gaps or rot in the decking foundation create weak spots that can be prone to leaking, and are dangerous for those that might walk the roof. 

It removes excessive weight bearing down on your home.  Shingles are heavy - some 200-250 lbs/square!  While placing a second layer of shingles may be permitted in some jurisdictions, anything beyond that (a third or forth layer) is prohibited. There is no benefit to leaving the old shingles in place as somebody will eventually have to tear them off.

Step 2 - A² Shingles Roofing Process: “Repair Or Replace Bad Decking / Fascia”

 We repair or replace any weaknesses with “like” material – ie:  the same type (Planking; Plywood or OSB) and thickness (a slight change in thickness can be seen through the shingles). Repaired areas on a roof deck need to be as strong or stronger than the original building.  During this step we also replace any rotten fascia and fascia substructure.

Step 3 - A² Shingle Roofing Process – Install The Drip Edge And A Quality Underlayment.

We offer the best underlayment options at the best prices. The drip edge should go under the underlayment at the eaves, and over the underlayment on the rakes, for best protection. A properly Installed drip edge will accomplish the following at the very  least: 

  • Protect the roof edges from wind-driven rain.
  • Provide a “lip” for water to “drip” off of – instead of running down (and prematurely rotting) the fascia boards.
  • Provides a flat surface that keeps the overhanging parts of shingles from sagging.
  • Helps to keep insects and rodents out of the attic

Step 4 - A² Shingles Roofing Process – Installing Starter Strips On The Eaves And Rakes

We offer all options on starter strips, we prefer using starters to aid in efficient, straight and square installation. When wind blows on your house, the edges are a very vulnerable place where it can get under the shingles and start to blow off parts of your roof. The starter strip is fastened firmly to the edge of the roof, and a special bead of asphalt sealant is applied to the edge of the strip over which the shingles are installed. 

Step 5 - A² Shingles Roofing Process – Installing The Shingles

We typically use a 6-hit nailing pattern, which increases the wind-rating to meet 110 mph to 130 mph wind warranties (when used in combination with starter strip on the eaves and rakes).

Step 6 - A² Shingles Roofing Process – Address All Pipe Penetrations & Flashing Details

Most roofing leaks occur around pipe penetrations or at flashing locations. These are areas where there is a discontinuity in the roof surface, and where inexperienced roofers may not know or be willing to do what is necessary.  We have specific recommendations to ensure that any abnormality in the roof can be properly addressed. On pipe-penetrations a roofing-underlayment patch which is adhered above the pipe, emptying onto the shingles below. This way, if any water manages to get around the pipe boot it will be diverted back out on top of the roof surface.

Step 7 - A² Shingles Roofing Process – Ensuring Adequate Attic And Decking Ventilation

Most homes roofs lack proper ventilation, which affects your homes performance. Most Building codes require a 1:300 ratio of NFVA (Net Free Ventilating Area) compared to the footprint of your attic space. The best practice to follow (which some locations require) is a 1:150 ratio. Power turbines can be effective if there is adequate intake ventilation.

Ventilation is critical to:

  • Help to keeping your Air Conditioning bills lower.
  • Aids in preventing microbial growth in your attic (Childhood asthma and itchy eyes could mean your attic isn’t properly ventilated)

Step 8 - A² Shingles Roofing Process – Installing The Hip And Ridge Shingles

The hips and ridges of a roof experience the most wind in the event of inclement weather, and should be reinforced with advanced roofing techniques and products. We understand the importance of hip and ridge shingles, and utilize a specialty shingle to protect these vulnerable places on your roof.
