Composite Styles You Won't Believe

Do all roofs look alike? Definitely not. Some homes require a special touch, like a slate tile or cedar shake roofing. But those beautiful options are costly and require more maintenance. Not anymore. With DaVinci composite roofing, installed by Allen Roofing & Siding, see how composite materials live up to the natural look of slate and cedar tiles, but without the ongoing maintenance, repairs and replacement issues of the traditional options.

Frequently Asked Questions

How do I know when it's time to replace my roof?

Homeowners should look for signs such as missing, cracked, or curling shingles; leaks in the attic after rain; significant granule loss from shingles; and daylight through the roof boards. An inspection from a professional can give you a definitive answer.

How much will a new roof cost?

The cost of a new roof varies widely, depending on the size of your home, the type of materials you select, and labor costs in your region. A detailed estimate from a professional roofing contractor will provide you with a clear cost based on your specific circumstances.

How long does it take to replace a roof?

Typically, roof replacement can be completed in a few days, but this timeline can be affected by the size and complexity of your roof, weather conditions, and the current workload of the roofing company.

What types of roofing materials are available, and which is best for my home?

There’s a wide array of roofing materials available, including asphalt shingles, metal, tile, and slate, among others. The best choice for your home depends on your aesthetic preference, climate, budget, and the structural strength of your home.

What is included in the warranty for a new roof?

Allen Roofing & Siding offers a workmanship warranty. Material warranties are also available from the manufacturer.

Can you work with my insurance for roof damage claims?

Yes, we can assist with insurance claims and ensure that you get the coverage you’re entitled to for roof damage.
