The answer to 'roof installation leaking' is that a leaking roof is a common problem that can have several causes, including improper installation, damaged or worn roofing materials, and issues with flashing or sealants. Symptoms may include visible water stains, peeling paint, and mold or mildew growth. In many cases, a leaking roof can be repaired, but the severity of the issue and the extent of the damage will determine whether a DIY fix is possible or if you need to call in a professional roofing contractor.
If the leak is minor and you feel comfortable working on your roof, you may be able to fix it yourself by replacing damaged shingles, re-sealing flashing, or applying a roof sealant. However, for more extensive damage or if you are unsure of the cause, it's best to have a professional roofer inspect the issue and provide a recommendation. Trying to tackle a complex roofing problem without the right skills and equipment can lead to further damage and safety concerns.
