How to Increase Your Roof’s Lifespan

The roof is one of the main features on buildings and determines the amount of protection that is offered on the home. Although roofing materials last several decades, they are considered to be an investment when they need to be replaced. Fortunately, there are a number of steps that homeowners can take to increase the lifespan of the structure.

Schedule Inspections

One of the most important ways to preserve your roofing materials and reduce the risk of damage or deterioration is to schedule an inspection every six months. Professional roofers will identify areas where roof repair is needed, which can include on the siding or on the roof deck of the structure. The roofer will also provide an estimate on when the materials need to be replaced in the future.

Clean the Gutters

The gutters should be cleaned out every few months to remove twigs or leaves that have accumulated in the metal structure. Debris that is left in the gutters for too long can prevent water from draining off of the home and will often damage the shingles that are installed. You can also look for leaks that may have developed in the gutters to determine if they need to be replaced.

Repair Leaks

Leaks are known to develop throughout the year but should be repaired immediately to reduce the risk of damage that occurs. Access the attic with a flashlight to look for areas where sunlight is coming through the roof boards. You can also hose off the roof with water to determine where moisture is coming through. The leaks can be repaired with tar that is applied underneath the roofing materials to seal off of the home.

Install Insulation in the Attic

Many people are unaware of how much insulation has a direct influence on the roofing materials that are installed. Hire roofing contractors to add extra insulation in the attic, which will prevent the roof from reaching both high and low temperatures throughout the year by eliminating drafts that may be present. This can prevent heat transfer during the summer months with acrylic and latex barriers that can be used.

Clean the Roof

Cleaning the roof is another important step to take to remove algae growth that often accumulates on the eavestrough due to moisture. Cleaning the roof will prevent dark streaks or stains from developing and will also prevent the algae from feeding off of microscopic particles in the limestone of the asphalt shingles. This will prevent decay from occurring and will even increase the appearance of the roof. It will even increase the energy efficiency of the roof by removing dark spots that can attract more heat throughout the year. You can find more info at the Cherry & Clark Roofing website.

What GHS Pictograms Mean

With the implementation of the Globally Harmonized System (GHS) for communicating, chemical-related hazards, GHS pictograms have become an important tool in relaying information from the manufacturer to the user where safe product handling is concerned. As part of the larger GHS classification system, these safety labels are designed to convey the information in a consistent manner regardless of who manufactures the product or in what country it is used.

There are nine standard pictograms used on GHS labels, plus a 10th one that is used to indicate biohazards. It has a round black border with the biohazard symbol inside it. Whenever this symbol is used, individuals handling the product should take precautions to avoid being exposed to a communicable disease, especially those that are blood borne like HIV or hepatitis.

The other nine GHS pictograms have a red diamond-shaped border. Some describe this diamond shape as a square standing on one of its corners. Regardless of the way it is described, inside the red border will be a black and white symbol that represents a particular type of hazard.

Health Hazard

The health hazard pictogram resembles a person’s upper torso, neck and head in black with a star-like emblem over the chest in white. Whenever this symbol is used on a label there is potential for the product to be a carcinogen. It could also mean that there are concerns with mutagenicity, reproductive, target organ or aspiration toxicity, or respiratory sensitization.

Exclamation Mark

This symbol refers to health hazards also, but to those that are more of an acute nature. Products that can be skin or eye irritants or skin sensitizers will have this pictogram on the label. It could also mean the product has some narcotic effects or can irritate the respiratory tract.

Skull and Crossbones

As one might expect, the skull and crossbones represents poisonous characteristics of the product. Whenever this symbol is part of the label, there is an acute toxicity risk. Even death from a short exposure is problem. Safe handling of the product should not be taken lightly.


The corrosion symbol is that of a product dripping from a test tube onto a piece of metal or onto a person’s hand. It is used to indicate the presence of acids or caustics that can cause chemical burns to skin or can corrode metal.


The picture of a flame in the pictogram means the product is flammable. It can also emit flammable gas or be an organic peroxide.

Flame over Circle

A flame over a circle means the product is an oxidizer. These chemicals support combustion and should never be stored in close proximity to flammables.

Exploding Bomb

This symbol designates explosive material or something that can react explosively with other incompatible materials.

Gas Cylinder

Products that are gasses and are in pressurized containers will have the gas cylinder pictogram as part of the label.


The environment pictogram shows a tree and a fish and is used to indicate the potential for aquatic toxicity of the product.
