Roofing installation is a long process that includes several steps. It requires specialized knowledge and skills, so it’s essential to choose the right roofer for the job.
Before the actual roof work begins, your contractor should lay tarps. This makes clean-up much easier, as it prevents debris from flying around your yard. Visit https://www.delaware-roofing.com/ to learn more.
A roof is one of the most important components of your home, providing protection from rain, snow and extreme temperatures. Roofing technology has evolved over the years, allowing homeowners to choose from new roofing materials that add aesthetic appeal and increase energy efficiency. A durable, sturdy roof also protects the inside of your home and everything inside it from moisture.
Clay or concrete tiles are a durable option for a flat or low-sloped roof. They provide a beautiful, rustic appearance and work well with Mediterranean, Mission or Southwestern style homes. Tiles are long-lasting and can withstand high winds, extreme temperature changes and hail. However, they are expensive and can add substantial weight to a structure, requiring additional framing.
Slate is another durable material that offers a classic, timeless look to a roof. It is available in a wide range of thicknesses and colors and can last from 50 to 200 years. It is also fireproof and resists high winds and extreme temperatures. Slate is typically more expensive than other roofing materials, but it comes with a manufacturer warranty that can offset some of the installation costs.
A caulking gun is an easy tool to use for putting down sealant, and it can save time and effort by dispensing the product quickly and evenly. A utility knife is handy for cutting shingles and underlayment, and you may want to invest in curved tin snips if you plan on doing a lot of curved work.
A roofing professional will examine your roof to look for signs of leaks, damage or deterioration. This involves a thorough inspection of the entire roof, including the attic and any areas where water penetration might occur.
Roof inspections should be done in the spring or fall, when weather conditions are mild and storms less frequent. The inspector starts by examining your attic space, looking for evidence of water damage or rot, and taking pictures of any visible problems. They will also look for loose or missing shingles, curling, or discoloration of shingle surfaces. They will inspect shingle granules, cracks, and rust on slate and tile roofs, and will check for moss and algae on metal roofs. They will also check that all flashing and membrane edges are secure, as leaks often begin in these areas.
They will examine the soffit material to ensure it is in good condition and that it extends to the gutters. They will check that the gutters are free of standing water and that downspouts are firmly attached and working properly. They will also check the fascias and drip edges for deterioration and rot, as well as for any signs of insect infiltration.
If the roof is too steep or hazardous to walk on, an inspector will use a drone to take photos of the entire structure from the air. They will then use the photos to compile a report of their findings and recommendations for any repairs or replacements.
After the ice and water barrier is laid (and fastened, if needed) the roofing contractor will roll out your new underlayment. This is a waterproof material that prevents ice dams and strong winds from pulling moisture into the house. There are different levels of thicknesses, and you can choose between paper or synthetic underlayment.
The first row of underlayment gets placed at the bottom edge of your roof and is fastened with cap nails, then overlapping rows get laid on top, nailing in the same way but with the nails further apart as you go up the roof. The last row of underlayment is placed along the roof’s ridge and should drop down on each side of the house and cover the previous rows.
Felt paper is another layer of waterproofing and helps to remove moisture that may be trapped under the shingles. This is rolled out in short sections and stapled to the deck, with each piece needing to overlap the one before it for adequate coverage. You also need to waterproof the roof valleys, which are the areas where the slopes of your roof meet up, forming “V” angles. They have a lot of water run through them, and underlayment and felt paper are installed in the same way but with methods that allow for proper coverage of the valley’s specific structure.
The shingles you choose will determine your roof’s aesthetic and long-term performance. While most types of shingles protect the roof equally, some offer superior curb appeal and longevity.
The most common shingle type is fiberglass-based asphalt shingles. They are inexpensive, relatively easy to install and can last 20 to 60 years. Asphalt shingles are available in many colors and styles, including architectural (also called dimensional) shingles that provide a more random pattern to add dimension or simulate the look of a wood-shake roof.
Special areas on the roof, such as valleys and eaves, require flashing to prevent water from seeping through the shingle layer. During the shingle installation process, it is important to complete all the necessary flashing work, including installing a pre-formed width of corrosion-resistant metal in open valleys. This is a crucial step for longer roof performance.
Also, if you have trees near your house, make sure to have them regularly trimmed to minimize the risk of falling branches slamming into or puncturing your roof. This may sound like an obvious tip, but it is a major factor in reducing the lifespan of your shingles.
Flashings are metal pieces installed in the most vulnerable points of a roof (chimneys, walls, joints and so forth) to keep water from entering the building through those spots. They are often made of galvanized steel to resist corrosion.
These pieces of metal are bent into shapes to fit the joint and then covered with a layer of roofing underlayment and shingles to create an airtight, waterproof seal. They are especially important in areas where the roof meets a wall, low points or valleys where two different slopes meet and roof protrusions such as skylights and vents.
There are three main types of flashing: kickout flashing, pipe flashing and valley flashing. Kickout flashing is the lowest step flashing at a joint and it deflects water away from the wall. Pipe flashing is used where the roof is penetrated by pipes, and valley flashing protects the intersection of two sloping roof planes where water can pool.
Long runs of flashing should have expansion joints built in to allow them to flex and move with the house as it expands and contracts over time. Specialized shingles are then used to cap the flashing and add an extra layer of protection to these critical areas. These shingles are cut to match the size of the flashing and are then nailed into place with roofing cement under them. This process is repeated for each piece of flashing and the top of the ridge is also capped with specialized shingles.
The ridge cap is the shingle that caps the peak of your roof, giving it a finished and attractive look. It protects the vulnerable area of the roof where two sloping sides meet and helps prevent water leaks, mold, and mildew. Ridge caps also provide a means of airflow, helping to keep your home cool and comfortable.
The typical ridge cap is made of the same material as standard shingles and comes in various colors to match the color and style of your roof. They are typically thicker than standard shingles and have a pre-bent design that allows them to easily bend along the ridge of your roof. They are also typically smaller than regular shingles, allowing them to fit closer together without losing their strength or durability.
During a roofing installation, ridge caps are usually fixed in place using an adhesive or roofing cement. This is often faster and more effective than using a wet mortar mix, which can be messy and time-consuming to prepare and apply.
When installing a ridge cap, it’s important to carefully follow the manufacturer’s instructions. You should use proper safety gear, including a harness and non-slip footwear, and work with a partner to minimize the risk of accidents. You should also choose a clear, dry day to avoid moisture that can lead to corrosion and weaken the materials used in the roof.
