Welcome to the MHI Roofing blog! If you’re tackling roofing replacement for the first time, there are several things you need to know to ensure the success of your project. Today, we bring your attention to common mistakes made during the installation of asphalt shingles and how these errors can cause problems for your roof down the road. 

Improper Nailing

Nailing mistakes can damage your asphalt shingles, paving the way for leaks. Incorrect nailing also makes asphalt shingles more vulnerable to strong winds, which can lift improperly nailed shingles. This allows wind-driven rain to cause water damage to the roof. If the wind is strong enough, it can even blow poorly nailed shingles off the roof.

Not Using Starter Shingles

The starter shingles provide wind and water protection at the eave and rake. If your roofing contractor doesn’t use starter shingles, then water channels can form where the shingles align across the first course. This leaves your roof deck vulnerable to moisture infiltration. It’s important to hire an experienced roofing contractor to avoid installation mistakes. MHI Roofing is an experienced residential and commercial roofing specialist that can guarantee a proper roofing installation.

Incorrect Shingle Alignment

Asphalt shingles should be precisely aligned both horizontally and vertically. A roofer must lay out each course of shingles in a staggered, stepped pattern. The shingles of one course must be offset from the shingles below to prevent water from seeping through to the roof deck. An improperly aligned shingle course is also very noticeable and gives your roof an unsightly appearance.
