10 Things that Damage A Roof

Most of the following 10 factors that damage a roof can be detected and repaired through the James Russell Roof Inspection with a continued inspection through our Roofing Maintenance ProgramBelow are some factors that can affect the life and performance of your roof and also potentially affect what’s under it.

Sun: Your roof’s materials deteriorate over time as a result of the sun’s heat and ultraviolet rays. On the sides that face west or south, this deterioration frequently happens more quickly.

Rain: Rainwater can destroy the roof structure when it seeps under roofing materials like shingles or shakes and makes its way to the roof deck. In addition to harming your roof, this additional moisture can also damage other parts of your home, such as the insulation, walls, ceilings, and electrical systems, by causing mildew and rot.

Wind: High winds have the potential to lift the edges of shingles or other roofing materials, forcing water and debris underneath. Your roof could sustain considerable damage from these winds.

Snow and Ice: Snow that has already melted frequently refreezes at the overhang of your roof. This develops an ice dam and prevents the gutter from being properly drained. Water will collect behind the roof and leak inside. Snow and ice damage to gutters and downspouts that may not be repairable or, in severe cases, are torn off a house or building can happen as snow and ice first begin to melt.

Condensation: Moisture from warm, humid air can do a lot of harm. Sheathing and rafters’ wood can rot in poorly ventilated attics due to moisture, which can seriously damage a roof’s structure. Installing larger or extra vents will provide adequate attic ventilation, which will help solve issues by bringing the temperature of the attic air closer to that of the outside air.

Moss and Algae: Moss often grows on wood shingles and shakes that are damp. Once it’s on your roof, moss holds even more water on the surface, which leads to rot. Moss roots can also grow into a deck or building made of wood. Algae can also grow in damp, shady spots on roofs made of wood or asphalt shingles. Not only does it leave an ugly black-green stain, but algae can also hold on to water, which can lead to more rot and decay. You should cut back your trees and bushes, so they do not touch your house. This will get rid of damp, shady spots. Gutters should be clear so that water can flow through them well.

Trees and Leaves: When the wind moves tree branches close to your roof, they can scrape and even puncture it. Leaves on your roof hold in moisture and cause rot, and leaves in your gutters stop water from flowing.

Missing Shingles: The whole point of a roof is to keep everything protected. When shingles are missing or torn off, water damage and rot can happen to the roof structure and the inside of a home or building. Missing or torn shingles not replaced immediately can cause shingles around them to fall off.

Shingle Deterioration: When roof shingles become worn, they curl, split, lose their waterproofing, and are easy to blow off, tear, or lift. The result is rot in the structure and damage inside. A roof that is not in good shape will only get worse over time, so the roof should be replaced as soon as possible.

Flashing Deterioration:
Most roof leaks come from the flashing. Without good flashings around chimneys, vents, skylights, and places where the roof meets the wall, water can get into a home or building and damage the walls, ceilings, insulation, and electrical systems. Checking the flashings is part of a roof inspection and gutter cleaning that should be done two times a year. 10
