6 Common Roofing Mistakes You Should Avoid

The roof is the first security layer of a house that keeps you safe from the weather elements like cold, heat, winds, rainfall, and storms. It is a costly investment, and should only be entrusted to the professional on any matters relating to repairs, replacement, or home improvement.

Any mistakes on roofing will not only cost you in related repairs later on, but it can also compromise the integrity of the house. Ensure your home is well protected with a good roof by avoiding these common mistakes that most homeowners make:

1. Hiring an inexperienced roofer

Hiring an inexperienced roofer may appear like a good decision at first since they are likely to charge less to get the roofing work done. This decision can lead to costly mistakes like redoing the roof again or suffering extensive damage to your home and property.

Choose to work with reputable roofing companies with extensive experience in roof installation, repairs, maintenance, and replacement. You will also need help installing gutters after the roof is completed, as both are equally important in protecting your home.

2. Delayed repairs and maintenance

One of the biggest mistakes that one can make with roofing is failing to carry out regular maintenance. It doesn’t matter if you use high-quality, long-lasting materials when building. Roof inspection, routine maintenance, and repair works are a necessity.

When cracks and defects on the roof become aggravated, repairing it becomes a costly affair. You will end up fixing more than just the roof, as the leaks can also cause issues with other things in the house. Delayed repair and maintenance work like the replacement of missing or broken shingles or leaks repair degrade your home’s interior and structure over time.

3. Improper application of nails

The roofer needs to apply just enough nails to hold the shingles and the roof in place. Too few nails may cause the shingles to slip off. Also, the roofer should nail down at just the right angle to avoid tearing off the mat and causing roof leaks.

4. Improper flashing installation

This is a common mistake that an inexperienced roofer is likely to make. Flashing will only work effectively when properly installed, which means positioning it under shingles. It should not overhang but should be just enough to prevent water from seeping in or being blown off by strong winds.

5. Poor attic ventilation

The roof shingles must be installed in such a way that there is enough space for air to escape from the attic. Lack of proper attic ventilation may lead to ice dams over winter, moisture build-up, and mold, which can damage the roof and also affect the inhabitant’s health.

6. Re-roofing over the old materials

It is possible to lay down your new shingles over old roofing materials. This may be pretty cheap compared to installing a new roof, but it poses many potential risks. It won’t be easy to inspect the roof as it might feel heavy over the old materials. Installing a new roof is expensive, but in the long run, it will save you money.


Installing a new roof is very expensive. It is vital that you maintain the one you have right now for as long as it is feasible. Discuss these mistakes that we have highlighted with your contractor to make sure that they are we
