Asphalt Shingle Roof Installation: Getting It Right

Posted on: 14 February 2016

The advantages of using asphalt shingles aren't just limited to the range of styles that a homeowner can choose from — they also extend to the fact that they are relatively cheaper, are lightweight enough not to need additional structural support, and are easy to maintain. However, for a homeowner to enjoy these advantages, he or she needs to properly install the asphalt shingles. The following are installation tips that will come in handy during shingle roof installation.


Underlayment usually acts as an additional layer of protection against moisture. Installing it is therefore a must for a moisture-proof shingle roof.

By acting as a shield against water leaks, underlayment goes a long way in helping to prevent premature deterioration of the roof support structure. It helps to prevent the rotting of wood and the rusting of metallic structures and fasteners. As a result, a properly installed underlayment usually goes a long way towards extending the lifespan of the entire roof. This, in addition to the fact that it helps prevent water damage, makes it a worthwhile investment.


Nailing of shingle roofs usually determines how resistant the roof will be to strong winds. And since nailing points present areas of weakness on a shingle, how one nails the shingles usually determines how waterproof the entire roof will be.

To ensure that the shingles are properly attached, it is advisable that you ensure that the nail penetrates the deck by more than 3/4 of an inch. Following the manufacturer's instructions as to the number of nails to use and how the nails should be positioned will also go a long way in helping to ensure that your roof is strong enough to withstand strong winds.

Starter strip

Starter strip installation is important mainly because of the added resistance to strong winds that it provides. There is also the fact that when these strips are properly installed, they can significantly reduce the risks of shingle water leaks, especially when the starter strip is overhung at the rake and eave edges.

However, while the starter strip is useful in helping to provide the roof with additional support, it is important to remember to not double stack the strips. This is because it will make the roof too bulky and thus increase the weight that the roof support structure has to handle. Double-stacking will therefore make the roof vulnerable to strong winds, something that may increase the risks of wind damage.
