    Roofing 101

    The Basics, straight to the point, only what you need

    In Roofing 101 we briefly break down the roofing process, go over materials that are used on every job we complete. We’ll briefly break down the different types of each material, when and if it is necessary, and shed some light on the roofing industry. We want our clientele as informed as possible, without actually putting you to work with one of our crews of course. And the following information will clarify some questions that we are asked by everyone who has contacted Bill’s Roofing for a new roof on their home.

    Sheathing

    Most older homes may have ship lap or Tongue and groove boards for their homes original sheathing type. Although these methods used to be reliable sheathing options, we’ve found over the past 15 years that these types of sheathing eventually warp upwards, pushing the shingles upwards, and allowing water to reach the nail line. This will cause your “brand new” roof to leak in 5 to 10 years.
    Solution: Installing OSB or CDX plywood over these old slat boards is the best and most common method to ensure we have a solid wood surface to nail to, while preventing the original sheathing boards from being able to warp upwards.

    Cedar Shakes

    We offer all kinds of cedar roofing and siding material for your home projects. Cedar shingles give your roof a natural look with a clean and low-profile appearance. Whether you prefer the western red cedar or an Alaskan yellow cedar, contact us to find out what type of cedars we can provide to make your roof look amazing.
    A skilled roofer lays down underlayment on a roof.

    Underlayment

    Commonly referred to as felt, is the vapor barrier tacked on to your plywood, to act as last line of defense, that is if some how it got passed our amazing & perfectly installed roof system…, your underlayment will be what keeps whatever “sneaky” rain drops and moisture that gets passed the shingles from being able to soak into your sheathing then rotting it out.
    Types: 15#-30# Asphalt Felt Paper is an asphalt soaked felt paper that has been around for decades and are proven options for your underlayment needs. But they are considered as only a water “resistant” underlayment, which brings us to the newer underlayment option.
    Synthetic Underlayment is basically a tightly weaved “plastic” underlayment that is considered to be water “proof” thus allowing no water to eventually absorb into the underlayment itself and over time contacting the sheathing. Both options are both proven to work. Synthetic is obviously more expensive. But in most the minds most journeyman, the same result is obtained with both materials.
    A skilled roofer works at sheathing the roof while handling the roof's insulation.

    Ice & Water Shield

    Ice & Water shield is an adhered underlayment for certain sections of roofs that are susceptible to Ice damming. Basically, in higher elevations where there are elongated snow packs on homes, melting snow gets pushed back or sideways when it hits frozen snow and Ice near the gutter, around skylights, and in valleys thus causing water damage.
    Solution: Unless you live in Snoqualmie or cities with a lot of snow every year, this product is not actually necessary just costly. We obviously will install any product for any customer if they desire the added protection. But like I said previously, “straight to the point, only what you need”.

    "Don’t Over Think It, it looks harder than it really is."

    Roofing is a simple installation process of ensuring that everything over laps the thing below. Everything from the edge metal, underlayment’s, flashings, and shingles all follow this simple process where the upper course overlaps onto the lower course so rain traveling down to the roof slope never meets any resistance and never has the opportunity to go anywhere except in the gutter.

    Perimeter (edge) metal

    1”x3” starter metal is a 26gauge baked on enamel painted metal that is nailed onto the bottom or gutter edge of your sheathing to prevent water from potentially rolling back and hitting your plywood. This flashing is a “must” on every roof and comes with every Bill’s Roofing roof. If another roofing company doesn’t suggest it……… well you know what to do.
    Drip Edge Metal is a 26gauge baked on enamel painted metal that is installed over your gable fascia boards to prevent water from rolling off the ends of the shingles, back to your fascia boards, and deteriorating them quicker. This is another must in our opinion as fascia replacements can be a costly process.

    Vents/Ventilation

    Hooded vents are the most common type of attic exhaust vents. (the mushroom looking things near the peak of your roof) These allow for hot air to escape your attic space to prevent condensation and potential rotted sheathing. 
    Ridge vent is the alternate option. Originally invented for homes that have vaulted ceilings, ridge vent is a superior ventilation system that allows for maximum ventilation of your attic space. We recommend ridge vent on almost every home. 
    Roofing Material
    There are so many manufacturers and products we can get into them all. Do your research on the various products to have an idea of what you would like. We will recommend the best material for your home, and will never put a material on that doesn’t meet the requirements for your pitch and situation.
    We hope this information was helpful and useful to all our clients. We are here to help no matter the situation.
