Things to Take Into Account when Buying Roofing Materials

When it comes to changing the roof of your house there are several things to take into consideration when buying new roofing material. Furthermore,
you need to keep an eye on the roofing contractors you hire for the job in order to make sure they work properly and don’t skip any steps.

Any of the Atlanta roofing contractors you ask will tell you that a roof’s system performance can be affected by many factors, that is why knowing
about these factors will help you make an informed decision when buying material for your new roof.

Ultraviolet rays and heat can lead over time to roofing materials deterioration. Roof degradation can occur quicker on the sides facing south and
west. Another factor to take into consideration before you buy your roof materials and hire a team of Atlanta roofing contractors is rain. If water
manages to get underneath shakes, shingles or other roofing materials, then it can infiltrate in the roof’s deck and cause the structure to rot.
Humidity and moisture can lead to mold and rot not only in your attic, but in your ceiling, electrical systems, insulation and walls.

High winds can lift the edges of your shingles and water and debris can work their way underneath your roof. Furthermore, extensive damage of the
roofing is caused by extremely high winds. Snow and ice can also cause damage to your roof. Many times melting snow can refreeze at a roof's
overhang where the surface is cooler, thus forming an ice dam. This will block your drainage and water can back up under the shingles or other
roofing materials and seep into the interior. The downspouts and gutters are the first to fill with ice during the early melt stages and it can
damage them beyond repair. Blocked gutters and downspouts can even tear off a building or a home.

Trees and leaves can also cause problems because when tree branches touch a roof they will scratch and gouge roofing materials when they are blown
by the wind. Shingles can be damaged or punctured by the falling branches from overhanging trees. Rot is caused by leaves that fall on a roof
system's surface because they retain moisture. Leaves can also block the drainage system.

A properly installed roof is very effective in protecting your house. But when shingles are missing or torn off, a roof structure and the interior
of your house are vulnerable to water damage, rot and mildew. In case of ripped shingles it is very likely the problem will spread to the nearby
shingles. Therefore, ripped, torn or missing shingles must be quickly replaced.

Condensation can result from the buildup of relatively warm, moisture-laden air. A poorly ventilated attic can lead to moisture which promotes decay
of rafters and wood sheathing. This can destroy a roof structure. So it is always a good idea to spend some money on additional vents and place them
in the attic in order to keep the air temperature closer to the outside air temperature.

Moist shakes and wood shingles can develop moss which can hold moisture to a roof system's surface, causing it to rot. Plus, moss roots can grow
into a wood deck and structure. In the damp and shaded areas of wood asphalt shingles algae can grow and create a black-green stain that can retain
moisture. This also leads to rot and deterioration of the roof. In order to eliminate damp and shaded areas, trees and bushes must be trimmed away
from houses. Gutters should be kept clean in order to provide proper drainage.
