Proper Asphalt Shingle Installation and Care

Apr 13, 2021

Roofing shingles and underlayment work together to provide your home with protection from the elements, including rain, snow and wind.

But these roofing products can only do their jobs when properly installed.

Shingles have specific guidelines for how they should be secured to your roof.

They relate primarily to the quantity, location, and driving method of the roofing nails.

Proper installation is essential for optimum shingle performance, and for compliance with the International Building Code.

Some roofing nails are more suitable for certain geographies than others. For instance, if you live in a coastal area where your home is exposed to salt, stainless steel roofing nails may be a good choice. Galvanized roofing nails tend to resist rust formation, and they are a suitable option for asphalt shingles.

When nailing shingles, proper penetration into the roof deck is essential so that nail and shingle remain secure. On Roofing Solutions applications, we ensure roofing nails penetrate completely through the roof deck.

Each shingle manufacturer has its own requirements for proper nailing, including where roofing nails should be placed. Typically, the merging of the upper and lower portions of the Architectural Laminated shingle construction involves a reinforced, tough, engineered fabric strip embedded on the face of the shingle that offers nail pull-through technology and nail blow through resistance while providing a highly visible nailing target for roofing professionals.

Traditional shingles (Three Tab shingle construction) also have a similar middle ‘nailing area’.

It is important, however, to take care not to overdrive nails as this can lead to water intrusion via the overdriven nail through the asphalt shingle and eventually be introduced into the roof deck and the home.

It is just as important, however, like driving a car, that roof installers ensure that they stay in their lane…… Nails should not be visible.

Exposed nails, and raised nails are a sure path to water intrusion.

Thankfully, we do not have the issue of erratic nailing….. Because of our good men, who take pride in their work, we have not had a callback, or a roof leak on our new installations in almost 7 years!…..this is a pretty incredible statistic, one we are proud of and thank our men for each and every time we have the opportunity.
