5 Most Common Roofing Problems: Causes, Effects, and Solutions

5 Most Common Roofing Problems


Your home’s roofing system is responsible for protecting you and your belongings from the elements. However, it’s not uncommon for homeowners to experience common roof problems over time. From structural damage to damaged shingles, there are several issues that can arise. In this article, we will discuss the 5 most common roofing problems, their causes, effects, and solutions.

  1. Damaged Shingles

One of the most common reasons for roofing problems is damaged shingles. Over time, shingles can become loose or break due to exposure to the elements, particularly UV rays. Damaged shingles can lead to leaks and other problems. In addition, damaged shingles can also be an indication of deeper structural problems with your roof.

Solution: If you notice any problems with your shingles, it’s important to contact a qualified roofing contractor as soon as possible. A professional roofing contractor can inspect your roof, identify the problem and offer solutions for repair or replacement.

  1. Flashing Problems

Flashing is a material used to seal and protect joints and seams in your roofing system. Flashing problems are common on flat roofs and can lead to leaks if not addressed promptly. Common causes of flashing problems include poor installation, damage due to weather, and normal wear and tear.

Solution: Regular inspection and maintenance of your roofing system can help prevent flashing problems. If you notice any issues with your flashing, contact a qualified roofing contractor for repairs.

  1. Structural Problems

Structural problems are common on older roofs or those that have been subjected to severe weather conditions. Common causes of structural damage include high winds, heavy rain, and snow accumulation. Structural problems can cause your roof to sag or even collapse.

Solution: If you suspect that your roof has structural damage, contact a professional roofing contractor immediately. They will assess the damage and determine if repairs or replacements are necessary.

  1. Roof Leaks

Roof leaks are one of the most common roofing problems that homeowners experience. Leaks can be caused by a variety of factors, including damaged shingles, flashing problems, and structural damage.

Solution: The best way to prevent roof leaks is to have your roofing system inspected regularly by a qualified roofing contractor. They can identify any potential issues and make repairs before they become major problems.

  1. Inexperienced or Poorly Qualified Roofing Contractors

One of the most common reasons for unnoticed roofing problems is the use of inexperienced or poorly qualified roofing contractors. This can lead to improper installation, low-quality materials, and a host of other issues.

Solution: When hiring a roofing contractor, it’s important to do your research and choose a qualified and experienced professional. Look for certifications, licenses, and references from past clients to ensure that you’re getting the best service possible.

In conclusion, your home’s roofing system is an essential part of your home’s protection. While roofing problems are common, they can be addressed and prevented with proper maintenance and repair. By staying vigilant and addressing any issues as soon as possible, you can keep your home and belongings safe and dry for years to come.

What can I say? Bruce and Keith provided an exceptional service, and they are really nice guys too. Found out at the last minute they were in Minneapolis, and they fit me in for a cedar shake roof cleaning the next evening after their regular job was done. Even cleaned up my gutters, small fence, and small deck at no charge. The place looks outstanding! Highly recommended.

I highly recommend this business. Due to the work performed we are going to get another 10-14 years out of our cedar shake roof. We were told by some roofing companies that the roof should be replaced in 2 years. I lucked out and found Sullivan Roof Cleaning while researching companies that perform this service, and was pleased to learn that the company does work outside of Iowa. If you need your cedar shakes cleaned, go with Sullivan Roof Cleaning.

Bruce did a great job cleaning the whole exterior of my house. The roof has new life! It looks practically brand new. All the mold and moss on the roof, on the gutters, under the eaves, completely gone. He exceeded all our expectations. When he tells you what he can do for your house, you can believe and trust him. Great guy, great service.

Cedar shakes are organic. Though a resilient material. Being organic they need to be maintained. Over time, like any organic material that are subjected to weather elements, they reach a stage of deterioration. Like UV exposure, moisture and seasonal changes. Which results in moss, mold, mildew, lichen and brown rot fungi. These infestations need to be removed to further preserve the integrity of the cedar shake.
The proper way to clean a cedar shake roof is from a ladder. By spraying a special formulated solution onto the shakes and then rinsed with a garden hose pressure. Best done by a professional cedar shake roof cleaner. Not DIY recommended.
No. Pressure washer will require walking on the shakes, which will harm them, and even at its lowest setting will also damage the shakes.
On average, cedar shakes should be cleaned every 10 ten years. Subjective to the grade of the shakes and the amount of surrounding tree cover.
Avoiding walking on a cedar shake roof, other than for repairs.
Never seal a cedar shake roof. Cedar shakes need to breathe. They expand and contract in rain conditions. Seal will shorten the lifespan, to the point of premature replacement.
Staining has no real preserve value and can also harm the integrity of shakes, as stated, they need to be able to breathe. Also, if the shakes are not properly cleaned staining can seal the deteriorating infestation within the shakes.
Depending on the grade of the shakes and installation, and if maintained properly, 40 to 60 years.
