10 roofing mistakes to avoid

Roof Repair

Your roof is an important aspect of your home. It is an essential barrier against the elements and a visible part of your home’s exterior. When everything is ok, your home stays dry when it rains, warm when it’s freezing outside, and cool when it’s hot outside. A damaged roof, however, can lead to further damage, annoying issues and unwanted exposure. That being said, it’s crucial to have a roofing company do repairs quickly. Finding a highly experienced and skilled roofer ensures you avoid the following roofing mistakes.

Covering old shingles

Broken shingles need to be replaced, not covered. Covering old shingles with new shingles creates spaces for dirt and moisture to collect. It can cause damage and deterioration. The roofing contractor should remove old roofing materials prior to installing a new roof.

Reusing old flashing

Metal flashing prevents moisture from leaking into your house at vulnerable places like valleys, skylights and chimneys. Some roofers reuse old flashing to reduce expenses. This could lead to other problems down the line. Make sure the roofer replaces old flashing with new, durable flashing.

Improve moisture protection

Shingles do a nice job of diverting water off the roof. However, it’s important to install proper moisture protection underneath. The moisture barrier protects your roof deck from collecting moisture such as snow and rain.

Incorrect fastener length

Using short nails to fasten your shingles is not a good idea. It can lead to loosening or shifting of shingles. To avoid premature repairs and replacement, use longer nails. Proper fixing ensures you are safe from displaced and shifting shingles.

Incorrect nail placement

Besides fastener length, proper nail placement is vital. When nails are placed incorrectly, serious structural issues can arise. Do not leave the nails exposed to wind, moisture and the sun. Instead, place them underneath shingles. This prevents corrosion.

Improper flashing installation

Once you replace your old flashing, make sure the roofing contractor installs the new flashing correctly. If it’s poorly fastened, misaligned or wrongly covered, your roof may not be able to protect you from snow and rain.

Mismatched slate colouring

If you choose a slate roof instead of a shingled roof, then you should check how well the slates match. Have the contractor inspect the slate before installation. The slates should have a uniform colour. You don’t want your roof to look like a rainbow.

Improper overhang

If the overhang is insufficient or poorly installed, expect wind damage. To protect your roof from wind damage, ensure that the roofer uses the right number of fasteners and installs the proper amount of extension.

Improper ventilation

When doing replacement or repairs, many homeowners ignore the importance of ventilation. High-quality roof restoration contractors use advanced materials to make the roof structurally sound and properly vented. Poor ventilation leads to moisture collection and heat build-up.

Decking issues

Ask the roofer to inspect the roof deck to ensure that it is properly installed and in good shape. Furthermore, it should be sheltered from the elements using shingles and moisture barriers.
