5 Common Errors in Home Roof Installations and How to Avoid Them

Are you a first-time homeowner looking to install a new roof on your property? 

Before you jump into hiring a roofing contractor that looks nice on paper, read on. When it comes to installing your custom new home roof, you want to look for certain key errors before it’s too late.

Below we’ve shared the top common errors in home roof installations and what to look for in an installation.

1. Don’t Neglect Ventilation

Gable vents at the eaves permit air to circulate through the attic, while ridge vents help equalize the temperature of the attic and prevent moisture and heat from building up inside the attic.

By properly venting the attic, it can help extend the lifespan of the roof and reduce the risk of structural damage to your home. Neglecting to properly vent a roof can lead to costly repairs and a decreased lifespan for the roof itself. 

2. Failing to Secure the Roof Deck Properly

Common errors made when failing to secure the roof deck properly include using incorrect angle nails or inadequate or old fasteners, incomplete fastening of the deck to the joists, failure to lap the shingles properly, and failure to properly seal around obstructions.

Additionally, an improperly installed roof deck can cause the joists or rafters to sag, weaken the rafters, or cause them to crack, potentially leading to dangerous structural failure. 

3. Underestimating the Need for Flashing

Underestimating the Need for Flashing is increasing in frequency due to DIY installations or budget-minded contractors. Ignoring flashing runs the risk of water penetrating all parts of the roof and the side walls.

To avoid such damage, all areas of the roof should get proper attention, and the need for flashing should not be underestimated. When installing flashing, rot-resistant materials should be used, and the flashing should extend at least 6 inches beyond any joint. 

4. Skipping on Proper Sealant Applications

Common errors in home roof installations can be costly, particularly when it comes to skipping on proper sealant applications. Roof sealants help to protect roofs from the elements and must be applied properly during the installation process.

If the sealant is not applied correctly, gaps between the roof shingles and the plywood or structural decking can occur, causing water intrusion and consequential mold and rot. If the sealant does not form an adequate bond, the shingles can flake or crack, or the roof can even develop leaks. 

5. Overlooking the Necessity for Ventilation

When it comes to roof installations, one of the most common mistakes is overlooking the need for sufficient ventilation. Improper ventilation can lead to problems such as moisture buildup, condensation, and the deterioration of roofing materials.

When the roof doesn’t have enough vents, hot air becomes trapped and is unable to escape, creating a situation where moisture and heat buildup is more likely.
