You've decided you need a new roof. Various contractors have given you estimates. How do you know that is correct for you? It's crucial to know precisely what the contractor is proposing when generating a decision in your roof replacement. You will find generally several products/services incorporated on most re-roofing quotes.
SHINGLES
The major item on a roof replacement estimate would be the actual roofing material. The estimate will list the manufacturer and kind of shingles the contractor intends to make use of. It will also show the style of shingle. Architectural or dimensional shingles are the most preferred. They make much more interest and frequently mimic the appear of other roofing supplies including slate or tile. It may contain colour decision or alternatives if design was a part of the initial discussion. The estimate will also indicate the length from the manufacturer's warranty for that form.
FLASHING
In case your roof has chimneys, dormers, and walls, then you will see flashing in your estimate. Flashing prevents water from seeping behind and beneath shingles, causing water harm for the structure.
Flashing is normally thin sheets of aluminum or galvanized steel. A lot of qualified roofers will fashion their own from sheet metal. Flashing is installed more than joints within the roof & wall construction. Possible areas are valleys, chimneys, dormers, windows, pipes, skylights, porches, decks and edges.
New flashing is normally installed with a brand new roof. If flashing deteriorates or comes loose it can cause severe damage to your home. It's essential to make sure it can be installed properly to avoid unnecessary damage.
UNDERLAYMENT
One item that should be included on every roof replacement estimate is underlayment. Underlayment is a layer of protective material between the roof deck or plywood and the shingles. Generally called felt paper, it is actually the first layer of waterproofing for your roof.
Manufacturers reinforce the underlayment with fiberglass to strengthen and resist tearing, make installation easier and improve its waterproofing effectiveness.
Manufacturers are constantly developing new underlayment technology. Newer synthetic underlayment further increases the effectiveness, ease & safety to install and increases longevity. Some manufacturers have developed organic and green underlayment goods.
It is generally recommended to make use of underlayment from the same manufacturer as your shingles as they are designed to work together. It might be required for a valid warranty.
A contractor will choose the best form of underlayment for your roof replacement based on the type of roof and climate in which you live. If you have any questions regarding their choice, they will be the best resource for your specific project.
DRIP EDGE
Drip edge is another crucial and sometimes overlooked a part of a roofing or re-roofing job. Even though manufacturers recommend it, and some require it for a valid warranty, some contractors do not incorporate drip edge on their estimates.
Drip edge is metal strips applied along gutter lines, eaves and some rakes. It stops water from getting under the shingles and damaging the deck plywood and protects fascia. Properly applied drip edge will lengthen the life on the roof and further protect the home from water damage.
Drip edge is not expensive to consist of in a roof replacement project and the benefits greatly out way the cost.
ICE & WATER SHIELD
The purpose of a roof is to protect the home from the elements; wind, rain, ice, etc. In most climates, ice and/or water are a concern you can't ignore.
Ice and water protection should be discussed for almost every residential roofing project and will likely appear on your estimate. Ice and water barriers allow proper water flow preventing damage caused by high wind and rain storms and ice build-up known as ice dams. It strongly adheres towards the plywood roof deck providing a second line of defense for the underlayment. The barrier is applied to the most vulnerable parts from the roof. Depending on the sort of roof this could be the valleys, eaves and rakes, or the entire deck surface. Contractors may perhaps also suggest applying it around chimneys and other areas where leaks are likely to occur.
VALLEYS
A valley could be the angle formed by the intersection of two sloping roof planes to provide water runoff. Because of your amount of water passing through that area of a roof, it is actually important to consider how the area will be protected when replacing an asphalt shingle roof.
You will discover different methods for shingling the area with dimensional asphalt roofing material. Closed cut valleys are most well-known aesthetically. In a closed cut valley application, shingles from one side of the valley extend across the valley while shingles from the other side are trimmed back a few inches from the valley centerline. Any flashing is not exposed. When using the open cut valley roofing method the flashing is visible. Open cut valleys may well be used to build visual interest or enhance features on some design styles.
Some contractors will use ice and water shield under the shingles, others will choose to install metal flashing. Further, some contractors will install both for extra protection. A qualified roofing contractor will consider several factors and make a recommendation as towards the best method and style for the specific project. A detailed estimate will include these recommendations.
RIDGE VENT
All roofs will need to be vented to allow moisture to escape and prevent harm to the roof and the entire home. You can find many types of roof ventilation systems. One of the most well-liked are ridge vents. They are installed along the ridge or peak on the roof and allow hot air to escape and draw cool air inside the soffit vents.
A detailed roof replacement estimate will involve which form and style of vent is going to be installed. Ridge vents come in many styles to match the home, shingle design and style, and homeowner's preference as to how much they stand out or blend in with the rest on the new roof.
CHIMNEY CRICKET
If the home has a chimney, a experienced roofing contractor may possibly recommend installing a cricket if there isn't one already. A cricket is a peaked construction at the back of a chimney to help prevent snow and ice build-up and to deflect water around the chimney.
