How To Re-roof a House with Asphalt Shingles?
Reroofing a house with asphalt shingles can be daunting, but it can be done safely and effectively with the right tools and knowledge. Here’s a step-by-step guide to help you get started.
Choose the Right Time to Re-roof
The first step in reroofing your house with asphalt shingles is to choose the right time to do it. Ideally, it would be best if you planned to reroof during a dry, mild time of year when temperatures are not too hot or too cold. This will help ensure that the shingles bond properly and prevent any issues with expansion or contraction.
Prepare Your Roof
Before laying new shingles, you’ll need to prepare your roof. This involves removing any old shingles, nails, and flashing. You may also need to repair damaged or rotten roof deck sections and install new underlayment.
Install Drip Edge
Once the roof is prepared, you can start installing the drip edge. This metal strip goes around the roof’s edge to help prevent water from getting underneath the shingles. The drip edge should be installed at the eaves and roof gables.
Install Underlayment
Next, you’ll need to install the underlayment. This waterproof barrier goes between the roof deck and the shingles. Different types of underlayment are available, including felt paper and synthetic materials. Make sure to follow the manufacturer’s instructions for installation.
Lay the Starter Strip
The starter strip is the first row of shingles along the roof’s eaves. Getting this row straight and level is essential, as it will set the foundation for the rest of the shingles. Make sure to follow the manufacturer’s instructions for installation.
Install the Shingles
Once the starter strip is installed, you can start laying the shingles. There are different patterns and techniques for laying shingles, so follow the manufacturer’s instructions or consult a professional. Generally, you’ll start at the bottom of the roof and work your way up, overlapping each row of shingles to ensure proper water drainage.
Install Flashing
Flashing is a metal or plastic material that goes around roof penetrations. A good example is a chimney and vent to help prevent water from getting inside. Make sure to install the flashing properly and seal it tightly to prevent any leaks.
Install Ridge Vents
Finally, you’ll need to install ridge vents. These vents go along the roof’s ridge to allow air to circulate and prevent moisture buildup. Ridge vents should be installed near the roof’s peak and covered with shingles.
