Storm Damage Roof Repair

Nov 26

A basic understanding of the components of your roof will help you understand the estimates you'll be getting from contractors.

You can find out about the various parts of a roof in Parts of a Roof.

How they impact ventilation and the many types of storm damage roof repair

Decking can be described as a type of outdoor flooring (or sheathing).

Decking is typically made of 12-inch plywood and seals and strengthens the roof structure. It also provides a nail bed for the roofing shingles.

  • A roof's edge (or the edge of the eaves),

All the boards run along the roof's edge or eaves. Fascia can also be called fascia.

  • Attic

The roof's area is below. Ventilation is required in order to protect the roof from heat buildup in summer and winter. Click here to open the information box. Click here to open the more information box

  • Saddle

Rainwater is diverted around the chimney by a structure placed behind the chimney's higher side (or similar extensions to the roof).

  • Ridge

There is a horizontal line at the top of the roof.

  • Valley

The intersection of two roof slopes creates the "V-cut" angle.

  • Membrane to be used as an underlayment

This coating is made of asphalt-soaked felt or synthetic fabric. It protects the shingles against resin from the wood decking and decking from the weather. Roof ice damming should be avoided at all costs!

  • Membrane for the eaves

This protective membrane is placed underneath some or all asphalt shingles during winter to prevent water infiltration due to "ice dams."

  • Membrane to be used as an underlayment

This coating is made of asphalt-soaked felt or synthetic fabric. It protects the shingles against resin from the wood decking and also protects the decking from the weather.

  • Edge with a drip

Molding that protects roof edges and prevents water infiltration.

  • Ventilation on the roof

These enclosed plastic or metal constructions include apertures and fins that allow for optimal ventilation. Four open sides are the most efficient vents. They are raised above the roof and allow airflow to flow in all directions. For complete attic ventilation, an air entry must be made at the foot of your roof through the perforations in your eaves. This seals the underside of the roof and is typically made of perforated aluminum.

  • Deflector

To allow air to flow freely over insulation near the soffits, a piece of cardboard or polystyrene is placed between two rafters. There should be at most 2 inches of space under the decking.

  • Vent for the plumbing

A pipe that connects to the plumbing system through the roof. It allows wastewater to flow to the sewer or the septic-system leaching area.

The lights flash (joint covers).

Flashing can be made from galvanized steel, aluminum, or plastic. It can also be rigid or flexible. It is a type of resistant molding that prevents water from entering the roof through the passages. Flashing is used to flash valleys, chimney bases, walls, roof vents, and plumbing vents.

Shingles

Shingles are made from asphalt and fiberglass. They protect your roof from the rain and add character to your home.

  • Shingles Selection

Asphalt shingles are very popular in North America due to their low cost and easy installation. The waterproofing function of asphalt shingles is based upon gravity. Water can only penetrate so long as it is moving downward. Asphalt shingles can last 20-40 years.

It is technically possible to replace old shingles with new ones, but this is not advised as the underlying defects could cause distortions in the new covering.

Quality is the same as the thickness

If shingles are thicker or heavier, they will be more resilient to severe weather. Two types of fiberglass-based shingles are available:

  • Three-tab shingles have a single reinforcement layer. Laminated (or architectural shingles) have two or three reinforcement layers.

  • Laminate shingles are more costly but come with a longer warranty.

You should always have extra roofing shingles in case of roof repairs. In case of an emergency, keep track of the model and brand name. You can recycle old shingles.

It is good to be informed.

You may be familiar with buying shingles online. However, it is possible to find shingles on the internet. Be cautious of new materials that aren't in compliance with local building regulations. Asphalt shingles are widely used in construction and are certified to Canadian standards.

Understanding warranties

Asphalt shingle manufacturers initially offer a 100 percent guarantee. Laminates come with a 15-year warranty. Single-layer shingles usually have a five-year warranty. The refundable cost of the shingle will decrease over time until the guarantee expires. Labour is not covered at this point. Manufacturer warranties now cover blue-green algae growth and damage from strong wind.

  • Extended warranties are possible.

Extended warranties are available for roofing systems that include a selection of shingles, eaves membrane, and underlay. These expensive, but more ambitious programs provide coverage for material and labor for up to 50 years. As a result, only a manufacturer-certified roofer can perform repairs covered by such warranties. A guarantee can be voided if certain issues are present, such as inadequate attic ventilation or deteriorated decking. It is important to follow the recommendations of your contractor for corrective actions before the shingles can be installed. Ventilation: The different types of roofs

Your roof type will determine the minimum regulations you need to follow. Do you have a specific design or contour for your roof? This is because it could lead to roof deterioration.

You must also determine the slope of your roof. This is important in many ways.

  • Asphalt shingles are used to cover slopes that are at least 1:13 (in the metric) or 412 in the imperial (in Imperial measure).

  • The second is that the materials and installation must be suitable for the roof's slope. A shingle roof covering will not be waterproof unless it is necessary.

  • The type of roof will determine the size of the ventilation apertures needed to maintain adequate airflow. Except in exceptional cases, ventilation apertures should not exceed 1:300 between insulated ceiling surfaces and their ventilation apertures. This means that for every 300 sq. feet of insulated ceiling, there should at least one square foot worth of ventilation apertures. For every 300 sq. meters of the ceiling, there should also be one square meter worth of openings.

Different types of roofs

  • The roof is flat.

  • If the roof slopes less than 212, it is considered flat. In this case, the ventilation apertures to insulated roof ratio should not exceed 1:150

  • The roof, without an attic, is called a "cathedral roof."

  • A roof without an attic should have a ventilation ratio between 1:50 and 1.50. The roof's summit and base should have openings.
