A roof protects a building against rain, snow, sunlight, and temperature extremes. The roofing material you choose can affect your home’s energy costs. You’ll also want to consider the drainage components of your roof. Downspouts can help direct rainwater away from your house. Open valleys are fitted with metal flashing.

Preparation

Installing a new roof is an involved process that includes many different steps. To ensure that the job goes as smoothly as possible for homeowners, there are a few important things they must do ahead of time. One of the most important things to do is prepare the area around the home where work will be done by Roofing Company. This will help protect the landscaping, furniture, trinkets, and other items damaged by shingles or other debris during construction. Additionally, it is a good idea to get tarps that can be placed under areas with the potential for nails or other debris to fall. This will protect the ground and make it much easier to clean up when the project is finished.

Another important step is to inspect the existing roof and make any necessary repairs. This is the only way to be sure that the new roof will be able to do its job of protecting the home and keeping it safe from rain and other weather elements. In addition, this is also the time to make sure that any gutters are in working order and free of blockages or damage.

Finally, it is a good idea to have the sheathing inspected and made ready for the new shingles or tiles. This is the inner layer of the roof that creates an outer barrier against water penetrating the house. This is usually made of plywood sheathing boards or 1 by 6 sheathing boards, depending on the type of roof. This is the time to replace any damaged or rotting boards that are found.

In this phase, flashing will also be inspected and replaced as needed. This is the metal material that is installed at the joints of the roof to prevent water from seepage. It is also used to protect the chimneys, skylights, and vents. In addition, it can be added to the ridge of the roof to provide additional protection there.

It is also a good idea to remove any children’s toys or other outdoor items from the patios or balconies near where the roofing work will be done. This will prevent the kids from getting injured by stray nails or other debris. In addition, it is a good idea to have any pets stay at a friend or relative’s house during the roofing process so that they are not disturbed or anxious.

Materials

The roof is the most visible element of any house. Replacing it with fresh materials can dramatically improve a home’s curb appeal. But a new roof also has energy efficiency benefits. If your roof reflects rather than absorbs sunlight, it can help control the temperature inside your home and reduce your cooling costs.

A new roof is a big financial commitment, but you can lower the upfront cost by choosing the least expensive materials. You can also save money by installing a roofing system that will last a long time, rather than one that requires frequent repairs.

Most homeowners choose asphalt shingles for their durability and affordability. But there are other options, including granulated metal, clay tiles and concrete tile. Asphalt shingles come in a variety of colors and styles, so you can match them to your home’s architectural style.

Roll roofing, or modified bitumen, is an inexpensive option that works well on low-sloped roofs. It has a tough, flexible membrane that holds up well in wet climates and resists punctures, tears and chemical spills. If you opt for a white or light-colored roof, it will reflect UV rays and cool your home.

If you want a roof with a more natural look, consider wood shingles or shakes. They start sandy brown and turn silver with age, and they can last 50 years or more in dry climates. Wood roofs need to be treated with fire retardant if they’re located in areas prone to wildfires.

Thermoplastic membranes (PVC, PU) are popular for flat roofs. These tough, flexible membranes are impervious to chemicals and can stand up to punctures, tears and bacterial growth. They’re easy to install, too, since they don’t require nailing or fasteners.

If you have a roof that’s in good shape but needs to be replaced, consider adding a new layer of shingle on top of the existing layers. Make sure to use No. 15 asphalt-saturated felt underlayment and lap the pieces over the lower ones by at least 2 in. This helps keep the roof deck dry before shingles go on, protects the underlying layers from moisture and prevents water leaks. Also, don’t forget to add drip edges along the rakes.

Installing the Shingles or Tiles

Installing roof shingles or tiles is a laborious and time-consuming project. It’s important to do it correctly or you could end up with leaky roofs and damaged walls and ceilings inside the house. The right techniques make all the difference and can help you get your new roof up and running as quickly as possible.

To start with, sweep the roof thoroughly and remove any large twigs or plant debris from its surface. You should also use this opportunity to inspect the ladder for safety and stability. If it’s not in good condition, it should be replaced before you attempt any work on the roof.

Once the roof is clean, you’re ready to begin laying out the shingles or tiles. If you’re re-shingling your entire roof, start at the bottom and work your way up, leaving enough space for each course of shingles to overlap the one beneath it by an inch. It’s a good idea to mark a grid pattern on the roof with a chalk line to guide you and keep the rows straight. For example, a grid with six-inch horizontal spacing and five-inch vertical spacing would be ideal.

The first row should begin with a full shingle and be nailed down to the underlayment with four or more nails. It should then be nailed to the shingle below it with an extra nail (called a starter shingle) at each end to secure it. When the last shingle of this row is nailed down, cut it to the size you need at the ridge and then bend it over the ridge and nail it again with another starter shingle at each end. This will prevent the ridge shingle from blowing away in high winds.

Some types of shingles, such as Coroshingle, require detailing strips to be fitted across the eaves, verge and ridge for a neat finish. If this is the case, follow the manufacturer’s recommended installation instructions to ensure that the details are properly applied.

You will also need to install any flashing that is required. This includes drip edge along the gutters and rake edge flashing for the sides of the roof. It is important to have this in place before you install the shingle course because otherwise water and ice can find its way underneath the shingles. In addition, chimneys and vent stacks should be surrounded with metal flashing that is laid over tar and then interlaced with the upper shingle courses.

Flashing

Flashing is a crucial part of roof installation that prevents water leaks. It’s made from thin, corrosion-resistant sheet metal bent into shape to fit a joint. When installed properly, it stops water from flowing through shingles and into the plywood decking and other components of your home. Flashing is particularly important in areas where the roof meets a wall (sidewalls and front walls), in low points on a sloped roof (called valleys), and around any roof protrusions, such as chimneys and vents.

There are several types of flashing, each designed for a particular type of roof penetration. For example, step flashing is ideal for where a dormer projects out from a wall. Without flashing, water could seep down the wall and slip past shingles into the structure. But step flashing solves this problem by lining the joint with multiple pieces of flashing that overlap like fish scales.

Another type of flashing is counter flashing. This is typically paired with base flashing and used to protect hard-to-waterproof areas, such as chimneys. Unlike base flashing, which is attached to the roof, counter flashing is attached to the wall and secured with roofing cement. This allows for expansion and contraction of the wall and roof during different seasons, reducing the risk of breakage.

Other flashing techniques include drip edges, which are installed along the edges of the roof to guide rainwater away from the fascia. Valley flashing is installed around any open valleys on the roof and helps to prevent debris build-up. Vent pipe flashing is used to seal vent pipes and other roof protrusions.

Although the installation of roof flashing seems complex, it’s a critical aspect of any serious roofing project. Getting it right ensures that your roof system is watertight and will protect the rest of your home from damage caused by extreme weather, winds, freeze-thaw cycles, and summer rains. It’s also one of the most common areas where homeowners experience leaks, which is why it’s so important to hire a roofing company that knows how to install and repair flashing correctly. Leaking flashing isn’t just a nuisance; it can cause significant structural damage to your home and lead to other problems, such as mold, rot, and insect infestations.
