Roofing Product Definitions and Warranties
Our standard shingles that we suggest to install are Certainteed Landmark shingles which are sold at Lowes. GAF Timberline shingles which are sold at Home Depot. Both rate high on consumer reports as best value shingles
Standard Manufacturer Warranties
The standard manufacturer limited lifetime warranty for Certainteed Landmark shingles and GAF Timberline shingles is as follows: The manufacturer warranties the labor and material for the first ten years. The material is then prorated warranted for as long as the homeowner lives in the house. The shingles are warranted Algae Resistant for 10 years . The wind warranty is 110 miles per hour for 15 years. This warranty will transfer for the first ten years only. Upgrades to 50 year labor and material warranties are available and have different requirements. Only Certified installers can offer upgraded warranties.
The link below is the Certainteed and GAF warranty:
Drip edge is a perimeter metal flashing that protects the fascia and edge of the roof. As water runs off of the roof, the process known as capillary action can cause the water to adhere to the shingle and wick underneath to the plywood sheathing and fascia board. Drip edge can prevent this action from damaging the roof or trim. Drip edge also offers further support for shingle overhang. Drip edge is an inexpensive way to protect the perimeter of the roof and the fascia from expensive repairs down the road. We recommend it but it is not a requirement to install a roof. We replace roofs every day that did not have drip edge yet no material was damaged because the previous roof and overhang was properly installed. Ridge Vent Ridge vent is a composite horizontal vent installed on the ridge of a sloped roof to provide humid air and heat exhaust. It is typically covered by shingles to finish and seal the product. It is installed with 2/1/2” roofing nails and typically has a filter within it to prevent insects from entering the attic spaces through the ridge vent. It is commonly called “shingle over ridge vent” because the shingles are installed over the vent. Ridge vent and attic fans should not be installed together as they tend to work against each other and limit ventilation from the entire attic space.
The majority of residential roof decks are comprised of either ½ inch plywood, ½ inch Oriented Strand Board (OSB), or pine ¾ inch x 6 inch tongue and groove. Replacement costs for decking depend upon the material used and the current cost of the material. Our normal pricing to replace decking is $40 per sheet for OSB, $50 per sheet for ½ inch plywood, and $4 per linear foot for tongue and groove. Discounts are given for excessive material replaced. Tongue and Groove can also be replaced with ¾ inch plywood for further discounts.
Soffit and Soffit Vents
The underside area below the eave of a roof is the soffit. Soffit vents are vents located within the soffit to provide air intake into the attic space. Soffit vents come in a variety of styles including 10 ft. strips, square cut in vents, and all in one vents such as Hardie board soffit and perforated vinyl soffits. Soffit vents are generally a necessity when using ridge vents for proper roof and attic ventilation.
Power thermostat controlled attic fans are used for roof ventilation. Attic fans are typically needed for hip roof construction or when there is no way to provide adequate soffit intake due to the design of the structure. Most attic fans are warranted for 5 years but can last much longer. Many homeowners with standard roof construction choose to remove the attic fan and install ridge vent for a no maintenance solution. We have found from homeowner feedback that attic fans tend to keep the attic cooler than ridge vent. However, they are not needed in typical home construction. We suggest attic fans vs ridge vent for hip roof construction, 3rd floor bonus room and vaulted ceiling spaces. Attic fans and ridge vent should not be installed together as they tend to work against each other and limit ventilation from the entire attic space.
Fascia is the horizontal finished trim at the bottom of the eave and the side of the rake. Gutters are typically installed directly on the eave fascia. Fascia repairs start at $12 per linear foot which generally includes painting. Discounts are given for excessive feet. Other pricing factors include type of material used, gutter removal and installation, and proximately of the repairs.
Step Flashing is an L shaped base flashing that is installed at a wall, chimney or other protrusions where a roof plane meets a vertical surface.
Counter or Apron Flashing
Counter Flashing is metal attached to a vertical surface that is installed over the step flashing to prevent water from getting behind step flashing. Most chimneys are flashed with step and counter flashing. Step and counter flashings are usually baked on enamel aluminum unless other material like copper is requested.
A cricket is a peaked saddle construction at the back of a chimney or other protrusion to deflect water around that protrusion. A cricket has an A frame design with two valleys on either side of the chimney or protrusion. Cricket are typically used on very large and wide chimneys.
A pipe collar is flange placed over a vent pipe to seal the roof around a roof penetration. Pipe collars can be standard, lead based, or have covers on them called Permaboots. Standard pipe collars are sealed around the top of the flange to prevent cracking.
There are typically two types of residential skylights made from various materials with various functions. Deck mount skylights are an all in one system (frame and top) in which the skylight is screwed to the deck of the roof. Deck mount skylights are typically made of tempered and low E glass and require their own flash kits for a proper and water tight finish. Curb mount skylights are skylight tops installed on a 2x4 or 2x6 framed base. These skylights can be made of glass or plastic. Manufacturer flash kits are typically available for standard sizes. Non-standard sizes require custom flashings by the installer.
Square vents are typically made of aluminum or plastic and are used to ventilate bathroom fans and other appliances from the home. Sometimes multiple vents are used to ventilate the attic when there is little peak space due to the home’s design.
There are many types of shingle underlayments on the market today. The standard is 15 pound tarpaper or felt. Upgrades to this are 30 pound tarpaper, synthetic underlayments and titanium underlayments. All serve the same purpose. They provide a flat surface for the shingles to lay on and add an extra protection to the roof deck for wind driven rain. Synthetics and titanium are stronger material and tear resistant. However, all are reduced as waterproofers once the nails of the shingles drive through them. It is our belief that upgrading the underlayment is usually a waste of money. Add Ice and water shield to the valleys and protrusions and upgrade the shingle instead.
Ice and Water Shield
Ice and water shield or “Ice Guard” is a fiberglass reinforced membrane that helps prevent wind-driven rain from leaking through the roof deck, or melting ice and snow (caused by ice dams in harsh winter climates) from leaking into property’s interior. It is typically installed in valleys and at eave edges— the most leak-prone areas of the roof. It is strongly recommended for chronic problem protrusions like skylights, dormers, vent pipes, chimneys, and other flashing areas.
Frequently asked questions
Why do I need ventilation?
Ventilation is crucial to the performance of a roof system. Ventilation eliminates heat, moisture, ice dams, and prevents mold. Proper ventilation will maximize the efficiency of your home and reduce heating and cooling costs. All major shingle manufacturers recommend adequate attic ventilation and require it for their extended warranties. Proper ventilation is also required by code for all new construction projects. Ventilation is a combination of intake and exhaust vents that creates a flow of air in the attic space of a home. Soffit Vents and Ridge vents are most effective form of ventilation in most roofing systems and are endorsed by the Federal Housing Authority and all major roofing manufacturers. This system creates year round benefits including cooler attics in warm temperatures and drier attics in cooler temperatures. In the summer, warm air is pulled through the exhaust vent preventing it from migrating to the living area and decreasing energy costs. In the winter, moist air is pulled through the exhaust vent preventing condensation in the attic that could otherwise damage wood and lead to mildew and mold.
What is the difference between an Architectural shingle and a standard shingle?
The most commonly known shingles are the 3-tab or strip shingle that has a flat appearance on the roof. An Architectural shingle has an additional layer of shingle material laminated on top to provide a more interesting appearance on the roof. Architectural shingles typically have a better warranty and better appearance than standard strip shingles.
What is the difference between woven, cut, and metal valleys?
A woven valley is a traditional method of installing shingles in the valley by interlacing the shingles as you go up the roof. The cut valley undelays one side of the shingle and then overlays the cut side for a different aesthetic appearance. A metal valley has metal installed up the valley and shingles cut on either side of the metal for a different aesthetic appearance. All three install methods are acceptable by all manufacturers and codes.
What is the black streaks or stains on my roof?
The black steaks or stains on the roof are Algae. Algae is a plant like organism that attaches itself to the roof. It is more prevalent in areas with high humidity. Algae is ugly on a roof but has no proven effect on shingle life.
How long will my shingles last?
This depends on the shingles and the climate. Today’s shingles carry warranties ranging from 20 years to lifetime. Generally speaking, you can expect the shingle to last within 5 years of the warranty period. The harsher the climate, the shorter the lifespan of the shingle roof system. Some general signs that the shingle life is coming to an end are curling shingles, cracking shingles, leaking in the fascia and soffit areas, and high amounts of shingle granules running into the gutters and out the downspouts.
What is the difference in price between shingle and metal roofs?
Typically metal runs two to three times more than shingled roofs installed depending on the type of metal chosen. Metal comes in a variety of styles, colors and widths. Most residential products carry a 40 year finish warranty with lifetime warranties available for extra charges. The benefits of metal do exceed that of asphalt shingled roofs. A metal roof will last longer. A metal roof is a radiant barrier so it will keep your house cooler. It is screwed in so it has a higher wind rating. Finally, it will also increase the value of your home
