 Dump Trailers Are Used For Trash Removal

G.W. Mangler Construction has had the opportunity to watch how our roofing systems have performed over years of exposure to the conditions that are encountered in our region of the country. We have applied this knowledge to the standard by which our roofing systems are installed today.

Ice Dam Formation

One of the biggest problems that affect roofs and homes in our region of the country is ice dam formation after times of snowfall. This happens when interior heat, leaks into the attic, and warms the underside of the roof deck. The warm roof deck and sun combine to cause the snow to melt on the roofs surface. This water then re-freezes at the cold eves and overhangs. As water continues to run down and re-freeze at the eves, it causes large ice formations, or dams, above the roofs surface. This water puddles up, and runs back under the roofing membrane and infiltrates the attic and interior of the home. Many contractors and homeowners are unaware of the importance of proper attic ventilation and attic insulation, in a balanced roofing system. Adequate attic insulation and attic ventilation can help stop the formation of ice dams, by ridding the heat in the attic.

Modified Bitumen Ice and Water Shield Ice Dam Image

Ice dams and wind driven rain are the culprits, allowing water to get under a roof’s outer shell.

Whether its shingles, slate, tile, cedar shake, or metal. And unless your roof is protected with a waterproof barrier, damage is the inevitable consequence.  Ice dams are those nasty build-ups that form on the gutters and eaves of roofs as freeze-melt cycles take place. The result is trapped water, which has been forced under the shingles, that will penetrate the deck unless properly sealed. Wind driven rain can also drive water up the slope of a roof, forcing its way under the shingles.

Ice and water shield is your best defense against interior roof leaks caused by ice dam formation and wind driven rain. Ice and water shield is a a modified bitumen waterproof underlayment, that is installed along all eaves, in all valleys, and around all roof penetrations. Ice and water shield is a major component of a properly working roofing system in our region of the country.

Integrity Roof Systems

Integrity Roof System (2)What are the elements of the CertainTeed Integrity Roof System?

​A superior roof is stronger than the sum of its parts. A quality roofing system involves the underlayments, shingles, accessory products, and ventilation all working together. Day after day, year after year. We call that the Integrity Roof System™. The Integrity Roof System is designed to provide optimum performance — no matter how bad the weather conditions are.

​A quality roofing system involves the underlayments, shingles, accessory products, and ventilation all working together.

​The Integrity Roof System is designed to provide optimum performance-no matter how bad weather conditions are. Better quality shingles mean longer-lasting roofs. Add in underlayment and accessory products, and you’ve got a roof system that really works.

​When you choose an Integrity Roof System you gain the advantage of having CertainTeed as your single manufacturing source to stand behind its roof system components.
