When doing DIY repairs on a roof, it is not uncommon to make errors when dealing with residential roofing. To save time and energy, inexperienced contractors may cut corners or work quickly, thinking that their techniques and materials are appropriate. As such, it is important to proceed with caution when undertaking any roofing tasks.
Be cautious of these 5 common mistakes when it comes to residential roofing:
1. Over-Patching
Repetitive patching of an area can lead to the development of cracks and/or leaks. It is more effective to conduct appropriate repairs instead of simply patching over a specific spot every time it starts to leak. The use of patch material can potentially trap moisture and cause neighboring shingles to crack or lift.
2. Inadequate Flashing Installation
Insufficient flashing can cause leaks at the edges of the roof and cause decay of the underlying wood and other materials beneath the shingles. Incorrect flashing not only compromises the corners and valleys of the roof, but can also result in water damage inside the house.
3. Poor Installation
Improper installation of the roofing materials can result in significant damage to both the interior and exterior of the house. Insufficient number of nails per shingle can cause them to lift, while excessive number can lead to cracking.
4. Shingles That Don’t Match
When fixing a roof, it is important to use shingles of the same size and type consistently. Using mismatched shingles can cause leaks or lifting, which can then lead to the wind catching the shingles and causing them to tear off.
5. Inadequate Attic Ventilation
Inadequate ventilation in the ceilings and attics can lead to the accumulation of moisture, which can cause mold growth and water damage. Effective air ventilation allows for proper air circulation, which can help to cool down the house during the summer months.
Experts in residential roofing will ensure that errors are minimized and the house is properly safeguarded against weather elements.
