There are various mistakes you can make when installing a new roof. You may end up with mismatched shingles due to buying supplies from different companies. You may place new shingles over old ones to reduce costs.
However, this mistake will prevent your roofing contractor from properly inspecting your roof. Also, you may not have proper ventilation in your attic. This mishap will expose the area to water damage, leading to mold and mildew growth.
Apart from the above errors, here are other blunders you can make if you install a new roof independently.
Asphalt shingles manufacturers provide guidelines on how to fasten shingles. However, you may find it hard to do so correctly. Usually, pneumatic nail guns are used to nail down shingles. Setting the pressure too high will drive the nails into the shingles too far. Overdriven nails will pierce through the shingle mat. This mistake will make the shingles vulnerable to damage, as they can come loose or get blown off.
Another mistake is improperly located nails. When nails are located too low on a shingle, they will be visible from the ground. Even though this accident might not be a concern, it could eventually cause. Conversely, nails located too high don't catch the shingles below. As a result, the shingles won't properly be fastened, so they can slip and pull out of the nail holes.
Roof overhangs prevent water from sneaking into the structural areas of the roof. The overhang shingles should have the proper measurement. Water can leak into the fascia boards if the overhangs are too short. Conversely, the shingles can be blown off during high winds and storms if they are too long. A roofer will help install the correct roofing overhang based on your roof type.
For example, shed roof overhangs are typically sloped to allow proper water runoff. Other overhang types include hip, flat, gable, awning, and canopy.
Not Replacing the Drip Edge Flashing
The drip edge plays an integral role in your roof's functioning, such as:
- Seals gaps at the bottom of the roof
- Prevents lateral movement of deck boards and fascia
- Protects the edge of the decking, avoiding water penetration
- Keeps the fascia from decaying by directing water away from it
- Assists gutters in diverting water from the foundation
You may be tempted to avoid replacing the drip edge flashing to cut costs. However, the component will get damaged with time due to wear and tear. A replacement is vital to enhance your roof's longevity and effectiveness.
