Many roofing contractors in climates with freezing winter weather also like to install a layer of moisture barrier at the eaves where ice dams might form. GAF’s moisture barrier is called WeatherWatch and Owens Corning calls its product WeatherLock. The roof decking is the layer of plywood or O.S.B. If you have any kind of concerns regarding in which and the best way to employ gatsni.com, you are able to e mail us from our webpage. nailed to the trusses or rafters. Roof decking is typically 7/16" and comes in 4’x8’ sheets. If you’re tearing off old roofing, the roofer can look for damage that needs to be repaired once the deck is bare. Repair is costlier on a per square foot basis because it is more time-consuming to integrate new shingles into the existing roof "here and there" than to install them over the entire roof.
In fact, the difference in pricing between a regular roofer and a GAF Master Elite certified contractor can be as high as 10% to 20%. I was given a quote of $10,250 for a GAF Timberline system. I’m trying to get solar panels and I was told that I need a new roof. I’m in Northern California, near Sacramento, but in a rural area, so housing prices are in the high $200k to low $300k. You should always aim to get a minimum of three to four quotes from professional contractors.
Use an 18- or 12-inch measure tape or level, measure one foot horizontally, then measure the vertical rise over that distance. If it rises 4 inches, for example, in the first 12 inches, your roof’s pitch is 4/12, or ⅓. In the short term, replacing a roof is a good investment because it updates your home's curb appeal. In the long run, it can prevent leaks, mold, and too much weight on the structure of your home, particularly if you live in an area that rains or snows a fair amount. Also known as a roof slope, "pitch" is the angle of your roof. Generally, the steeper the pitch, the more roof area to replace.
The job size is very small, so it would not be surprising to see a quote of $7,000 to $10,000 to replace the old 700 sq. Ft. cedar shake roof with premium shingles due to the small size of the project, removal of old shakes, installing plywood, and a hefty location premium. The existing single layer of 3 tab shingles are still in fine shape after 30 years, inspected and no damage underneath but the insurance company won’t insure the roof.
To be sure, some homeowners will get as many as 5 or more quotes. Lastly, it’s important to mention that a composition shingle roof like OC Duration, Timberline HDZ, or CertainTeed Landmark will not actually last for 50 years. The local real estate market in Kalispell Montana seems very robust based on local property values. This naturally increases the demand and going rates for home remodeling services.
The other 40% to 50% of total roof replacement costs go toward materials. An itemized list breaks down to the roofing material—shingles, shakes, tiles, etc—as well as the underlayment, new flashing, roof ridges and vents. You’ll also contribute to the cost of building supplies such as nails, tools, ladders and other related equipment. Composite roofing material looks like real slate or wood even close up, but it costs a lot less. And it weighs about the same as asphalt, so there’s no need to beef up the roof structure, as you would have to do to install slate. Made of a variety of compositions, including plastic/polymer, clay, rubber, and asphalt, composite roofing can be slippery.
These complexities require more skilled labor and can result in higher overall costs. Attempting to repair individual leaks may only provide temporary relief, and a full replacement may be necessary. Roof longevity depends on the material, your local climate and how well the roof was maintained.
So, the big unknown in this $65,000 tile replacement quote is the brand and the type of concrete tiles that contractor plans to install. We are missing some details, but let’s assume there is a dormer, a couple of skylights, and chimney. Let’s also assume there are already two existing layers of shingles, meaning the old roof needs to be torn off and disposed of. Yes, the actual roof area is always greater than the floor plan square footage of the house, because there are often two-foot roof overhangs on each side of the roof, plus the roof slope to account for. Some roof can also have peaks, dormers, and valleys that can add square footage to the topology of the roof.
While we strive to provide a wide range of offers, Bankrate does not include information about every financial or credit product or service. Congrats on getting 30 years of service lifespan from the old asphalt roof! Clearly your gable venting system is adequate, otherwise your roof wouldn’t last as long as it did. Leaving us to believe that the gable vents would be adequate with the ridge vent. Most Cool Roof rated shingles are either mid-range or premium product, so these shingles will normally last longer than low-end shingles.
