There are several parts of the roofing system and exterior walls that are prone to leaks and water penetration. These components are generally made up of valleys, drip edges, skylights, vent pipes, dormers, deck intersections and chimney perimeters. Locations such as these require an added protective layer that only properly installed flashing can furnish to effectively guard a building from water entry. For commercial or residential roofing, this component is vital in deflecting water away from seams, angles or joints and very useful in many different situations.

The information provided below will give some insight into the usefulness of flashing in every type of building construction.

There are several factors that can immediately affect the condition of a roof and one of these is damage caused by a recent storm. The extent of the damage may vary from highly visible indentations and breakage to virtually unnoticed depressions. Either way, a small amount of damage can surely hurt a roof's surface, eventually resulting in structural deterioration. Keeping this in mind, when a hurricane or storm causes severe damage to a home exposing essential structural components, immediate action must be taken.

The best temporary response to promptly address this type of issue is the use of a tarp. A tarpaulin is a sheet of waterproof cloth, either plastic or canvas, that is durable, pliable and resistant to water penetration. It is commonly used for an emergency roof covering to offer temporary protection over any storm-damaged areas that are open to the interior of a building.

Anyone who has a beautiful roof wants to preserve its beauty and ensure that it has many years of service and effectiveness. Hiring a reputable roofing company to maintain and inspect it on a regular basis is a way to accomplish this goal. It is inevitable that after many years of good service, a routine inspection may reveal that the once lovely and strong roof needs to be replaced. To accomplish this expensive activity cost-effectively will involve some education about the procedures involved and the potential cost for this major undertaking.

• Cost -There are many variables to consider when estimating the cost to re-roof a building. The biggest factors that will directly affect the cost include the: height of the house; materials that will be used; flashing; and slope at which the new roof will be installed.

Attic insulation is vital to a roof and yet is almost always part of a home that is neglected until problems start to occur. For both commercial and residential buildings, understanding the need for proper ventilation in an attic space is helpful for many different reasons, some of which are listed below.

Efficient Airflow

A roofing system needs to breathe properly for many reasons: to prolong the life of the material; to reduce mold and moisture problems; and to save on energy bills. With insufficient airflow, attic temperatures can reach an overwhelming level of 160 degrees during the summer. such high temperatures are capable of damaging the system by causing issues such as: premature aging of the material; cracking; warping; breakdown of wood trusses or framing; excessive use of cooling units; and damage to other parts of the house such as the siding, wallpaper, and exterior or interior paint.
