Roofing Questions Answered


What are the signs a roof needs to be replaced?

Leaks, missing or torn shingles, loose flashings, excessive shingle granules in gutters, and ceiling spots can signal roof problems. Age is another indicator; if your roof is 20 years old, it could be at the end of its lifespan.


My roof is leaking. Do I need to have it completely replaced?

Not necessarily. Our crews can often make repairs to extend the life of a roof that is otherwise in good condition. However, if a roof is demonstrating many symptoms of age and wear, replacement may be the only option.


How do I decide which roofing material to use?

Choosing which type of roof is right for you will depend upon numerous factors, including your budget, taste and needs. Before making your choice, consider the lifecycle cost of your roofing material. Some materials, although initially more expensive, require less maintenance and have a longer life expectancy than others. An asphalt shingle roof might last 20 years, but a metal roof can last more than 50 and might be more cost-effective in the long run.


How do I know if I have hail damage to my roof?

You may be able to see severe hail strikes from the ground, but most often hail damage is not visible to the untrained eye. If you’ve experienced hail in your area, call Knox's Construction to schedule a professional inspection.


What is an ice dam?

Ice dams are formed by the thawing and freezing of melted snow at the eaves. The ice dam can force water up and under shingles, causing leaks. In areas where winter temperatures frequently drop below freezing, ice dams can cause serious and expensive damage to a roof and to the structure of a home.


How long do asphalt shingles last?

Shingles come in different grades. The better the grade, the longer the life expectancy, which can range from 15 to more than 40 years.

What is the lifespan of a metal roof?

New alloys and coatings make metal roofing panels more durable, with extended lifecycles that exceed those of shingles or shakes. Today’s metal roofs can be expected to last at least 50 years.

How long will it take to replace my roof?

Most residential roofing jobs can be completed in a single day. If a roof takes more than one day, we clean and secure the site at the end of each day and take care to protect any vulnerable areas from the weather.

Will you clean up after my roofing project?

Yes. At the end of the job, we conduct a thorough clean-up and walk-through. You approve final cleaning upon completion, and we won’t leave until you are happy!


Make sure your home’s roof is ready to protect you from the elements.
