All Nether One Roof

While the shingles are all you see, a hard-wearing roof is considered a arrangement with many parts that work together to keep your house dry and comfortable. The focus is non merely on keeping the weather out but also letting fresh air in to prevent a buildup of heat and humidity in the attic. This is how your contractor will build your roof dorsum up later tearing it down to the three⁄8-inch plywood sheathing, or roof deck.

1 Ice AND WATER SHIELD

A cocky-agglutinative membrane applied forth the roof'south perimeter from the eaves up. It should accomplish iii anxiety beyond the within of the wall and cover any valleys to preclude water ice dams and wind-driven rain from reaching the sheathing. To shed water away from the eave, near roofers add together a metal drip edge right to the roof deck, covering it with the membrane.

2 UNDERLAYMENT

This synthetic layer, which replaces felt paper, covers the entire roof deck and is the 2d line of defence force confronting leaks, afterwards the shingles.

iii STARTER SHINGLES

A narrow row of asphalt roofing, the starter strip is nailed to the perimeter of the roof with a bead of agglutinative on top that grips the underside of the beginning course of shingles, keeping them in place during high winds.

four RIDGE VENT

Roofers use a round saw to cut a long slot forth the roof ridge—if there isn't ane—then cover it with a plastic flap (equally shown) or a flexible vinyl matrix. Openings forth the sides allow air out of the attic, cooling the infinite and lowering your air-conditioning bill.

Do a perimeter check. Earlier work starts, take your contractor motility outdoor piece of furniture abroad from the house and comprehend any valuable foundation plants. Afterward the roof work is done, ask him to walk around the house with a magnetic sweeper to selection upwardly stray nails.
Leave some behind. A bundle or two of new shingles, stored apartment in the garage, comes in handy if your new roof gets damaged later. Your contractor can and then utilize them for exact-lucifer patch repairs

Pro Tip For Low-Sloped Roofs

"While asphalt shingle is a good roofing material, information technology's not the best selection in all situations. Most manufacturers specify at least a 4:12 roof pitch for installing them, meaning for every foot the rafters extend out from the ridge axle, they drop down iv inches. If I'm using asphalt shingles I ever protect the sheathing with water ice and water shield beginning, pulling it onto the fascia and rake boards, and cover information technology with trim. I expose merely 4 inches of the shingle and drive in half dozen nails for better functioning in loftier winds and rain. On slopes less than four:12, I'll utilize EPDM rubber roofing instead, which protects against wind-driven rain better."

—Tom Silva, TOH general contractor

Option a Color: Black

It'south a big determination, just no need to panic. Architectural color consultant Bonnie Krims explains how a new roof tin can enhance your business firm's pigment job and boost its overall appeal.

Option a Color: Gray

Echoing the house colors in a roof shingle a shade or two darker is an easy way to get a unified look. Medium gray would flatter a yellowish-ochre or red business firm too. The midtone color here also lets the house'south white and red trim smooth through.

Pick a Color: Dark-brown

A ii-tone shingle adds interest when the business firm is one consistent color, as here. This pale-tan roof also picks upward shades in the flossy-yellow clapboards. Darker, reddish-brown roofs frequently cap off redbrick and off-white houses.

Selection a Colour: Carmine

While assuming, a red roof can be a expert fit for greyness, white, and taupe business firm colors. One mode to be certain: Pick a variegated red shingle that folds in some of the siding color, like this oxblood roof, which incorporates hints of the blue-gray clapboards.

Pick a Color: Green

Pick a Colour: Grayness-Blue

On smaller houses where dormers add color to the roof, wait for a dappled shingle. Here, the roof'due south lighter grey-blue tones reflect the house color, while the darker ones add residuum and accept a grounding effect.

Warranty Fine Impress

Shingle coverage Three-tab shingles usually carry a 20-, 25-, or xxx-twelvemonth warranty against manufacturing defects; laminated versions carry a "lifetime" warranty, which means for equally long equally you ain the business firm, or for a maximum of forty to fifty years. If the shingles fail at any point during that fourth dimension bridge, expect a check for a prorated amount.
Total coverage Some manufacturers offer more-expensive warranty packages that, if the roof fails within a set time frame, usually 25 years, they cover the cost of new shingles and the labor to reroof.
Second-owner coverage Buying a house with a new roof? Don't presume you're covered because the roof was recently installed. Inquire for the proper name of the manufacturer, notify the visitor of the change in ownership, and find out if the warranty transfers to yous.

Consider a "Absurd Roof"

Nighttime granules on laminated asphalt shingles absorb the sunday's radiations, pushing heat into the building, which explains why an attic can be l to 85 degrees warmer than the exterior temperature on a hot summer twenty-four hour period.

Cool-roof asphalt shingles assistance lower that departure to only v or ten degrees by using granules coated with a highly reflective paint. Some shingles are EnergyStar rated. Others have been tested past the Cool Roof Rating Council; when comparing these products, wait for the highest numbers in solar reflectance and thermal emittance, both on a scale from 1 to 100. Expect to pay anywhere from 10 to 50 percentage more than for cool-roof shingles.

While You're At It…Cupola

Earlier ridge vents became standard, cupolas were used to cool houses and barns. Fitted with louvers, or electronically controlled windows, they help draw absurd air in through soffits or open windows, then vent warm air from the top of the building.

While You're At It…Copper Gutters

Reroofing estimates oft include the cost of new gutters because your existing troughs accept to come off. Upgrading to copper gutters costs more than twice equally much as vinyl or aluminum, merely they add together fashion (and function) that should last a lifetime.

While You're At Information technology…Skylight

Brightening up a living infinite with a roof window might be easier than you think. First, the roofers cut the sheathing and frame an opening, and so cut a corresponding pigsty in the ceiling. A light shaft, built like walls, then joins the two to bring daylight into the house.
