No matter how durable or costly your roofing shingles are, improperly installing them would cause them to break sooner or later. The errors that happen in the installation of roofing shingles directly impacts their lifespan.
Mistakes Made By The Contractors
Finding a good roofing contractor makes it a breeze to get the roofing done in about no time. But here are some of the most common roofing mistakes that the contractors usually make.
- One of the main issue is the bad underlayment application. Underlayment is used beneath the asphalt shingles. If the moisture barriers are applied incorrectly, they can lead to leaks in your roof. This is a bug mistake that is often result of an inexperience. However, and experienced roofing contractor always makes sure to apply the roofing in a proper way to avoid all the leaks.
- Bad nailing practices is also a big factor that leads to the failure of asphalt shingle roofing. Loose nails can easily cause your shingles to blow off when a strong wind blows. This also makes leaks very much possible down the road. For proper nailing, follow the manufacturer’s manual. However, a general rule of thumb is that the nail should penetrate at least 3/4th of an inch into the deck to make them stick with the deck strongly. Applying the right number of nails will help to seal the shingles properly.
- Shingles should be applied at the rake first, and then you can continue to other parts of the roof. But this is not followed by many inexperienced roofers, and results in at improper application of shingles.
- Never use the old flashing when you’re replacing the roofing. It might look reusable at first, but it might have some punctures that may mess up the things later on. So, buy new flashing, it is very cheap as compared to the overall cost of new roofing.
