What does a bad roofing job look like?

What does a bad roofing job look like? Read on to find out. 

1. Sagging Rooflines- If you happen to look up at your home’s roof and notice that there is sagging on the roof, the framing could be problematic or there could be roof deck rot. This would mean that your roofing contractor did not take the necessary steps to pretreat and assess your old roof prior to the installation of the new roof. If this happens you should call and experienced contractor for an inspection to avoid further damage on the roof. 

2. Damaged or Missing Shingles- This is fairly common and is an easy repair, however damaged or missing shingles come with time and general wear & tear and should not be present following a new roof installation. Missing shingles following a roof installation is a sign that your roofing contractor was unprofessional or careless. 

3. Mismatched Shingles- Mismatched shingles are one of the easiest ways to spot a bad roofing job. 

4. Lack of Uniformity- After a new roof installation is completed on your home you should always have a very uniform appearance. You can check your roof out from the ground. If your roof looks to be different from both sides or the materials look to be inconsistent with curving or a dipped roofline, you could in fact have a defect with the installation. 

5. Reused Flashing- If you are having a new roof installed on your home you should in fact be getting all new materials installed and this includes any and all flashings. Bad roofing contractors tend to make this one of their first short cuts to reuse old flashings. Flashings should NEVER be reused as this can ultimately lead to leaks. 

6. Water Leakage- Leaks can start due to several different roofing issues. If you encounter a roof leak after a new roof installation you may have had a bad roofing job completed. 

7. Roof Stains- If you have recently had your roof installed and notice dark roof stains there may be a problem with the materials that are installed. Over time roof staining is normal, however a newly installed roof should never have roof staining. 

8. Missing Drip Edge– Drip edge is the term for metal that is installed on your roof to protect the decking that is below the edging. Good contractors install drip edge between the shingles and the underlayment to ensure that your roof remains structurally sound. If your roofing contractor did not install drip edge, your roof will be more susceptible to flooding, stains and mold. 

9. Missing Underlayment- Roof underlayment is necessary to make sure that your home remains water-free. The purpose of underlayment is to help create a waterproof barrier between the shingles and decking. In the event that your roof is installed without underlayment, your roof deck will deteriorate much faster and the lifespan of your roof will be much less. 

10. Wrong Nailing Technique- When you have a new shingled roof installed there are certain techniques that need to be followed when nailing the shingles. Wrong nailing techniques included overdriven nails caused by excessive pressure, nails that were installed other than in the nailing fin or nails that are susceptible to corrosion can cause major issues on your new roof installation.
