The Question: Can You Reroof Over An Existing Shingle Roof?

Many homeowners find themselves asking this question when they notice problems with their roof. For shingle roofs, when shingles are broken, falling, missing, or damaged,you still may be able to overlay the existing shingles with new shingles and save the cost and mess of tearing off the old roof.

Reroofing a tile roof involves replacing the old underlayment and flashings. Some roofers will lay new underlayment over the old, but generally this is a bad idea on tile roof. We always recommend replacing the underlayment.

Can You Reroof Over An Existing Flat Roof?

If your roof is flat and has some type of asphalt roll roofing, you may be able to do an overlay if the existing old roof is clean, dry and tight. Often asphalt rolled roofs are overlayed with sprayed polyurethane foam roofing.

Depending on your roof’s current condition, an overlay may not be the right answer. That’s why it’s important to have an honest assessment and all the information before deciding.

What Roofstar Says

Can You Reroof Over An Existing Roof?

A reroof involves replacing your existing roof covering. For most homeowners in Arizona, that means doing work on either shingles, tiles or flat roofs. Roofers will focus on repairing the outermost layer of your roof rather than the entire covering plus any supportive structures underneath.

You can re-roof over pieces of your existing roof if it only has one layer of shingles. However, roofs that need significant work may benefit more from a total roof replacement.

Can You Put One Layer of Shingles Over Another?

If your roof only has one layer of shingles, placing an “overlay” over the old worn shingles on your roof may be an option. Overlays, part of the re-roofing process, allow you to fix patches of your roof without having to replace the entire thing.

How Many Layers of Shingles Are Allowed on a Roof?

Arizona’s building codes allow residential homes to have no more than two layers of shingles on a roof. If your roof has two layers of shingles and is in need of repairs, you’ll most likely need to do a full replacement.

What Is the Longest Lasting Roof?

The longest-lasting roofing materials are concrete, slate, or clay tiles, all of which can last up to or over 100 years if properly installed and maintained.

Start Smart: Get the Truth About Your Roof

Deciding between replacing your roof and getting a re-roof can be difficult for many homeowners. Both options have different pros and cons.

I have had several neighbors ask about your company and have given favorable recommendations to this point. Your team was very professional and I think to this point did a great job! I am in sales as well and just to let you know Mike was very professional in his meeting with me and his presentation and follow up made the difference between other companies.

Jeff found problems we knew were wrong with our roof that other Roofers who inspected & gave proposals missed. He was very straight forward, honest & always making sure our questions were answered. He & his crew showed us materials being used & explained everything! He got on the roof during the work to make sure things were going right. His crew are outstanding, respectful, honest and very clean. Couldn’t be more satisfied!! He came highly recommended & we can see why! Thank you Jeff, Juan and Crew for all your hard work. They care & take pride in their work & customers!

After a monsoon storm ripped off half our asphalt shingles, I got several quotes from Valley roof companies. Roofstar impressed me with their quote, attention to detail, and quality photos showing the job as a whole. I went ahead used Roofstar, who replaced the entire roof while I was out of town and did a great job picking up the trash, sealing the A/C unit, and affixing new drip edges. I had a small issue with the new trim not matching the old color and the owner, Jeff, was kind enough to come back out and paint the trim himself. Would I recommend Roofstar to friends and family? SURE! They stand behind their work.

Roofstar provided professional inspection and detail quotes on the repairs needed to be done for our properties. We collected a few quotes from different roofing companies for comparison. Roofstar repair cost was very competitive and reasonable. We ultimately chose to go with Roofstar because we felt confident that they would take care of the problems. They came back to correct the minor issue that we had and finished the job to our satisfaction without further questions. We would highly recommend Roofstar to our families and friends.

The estimator, James, was very pleasant, thorough, and did a great job of explaining what was needed to repair our roof. We thought that the quoted cost was reasonable and decided to go with Roofstar. We are happy that we did. Juan Diaz and his crew did an outstanding job with the repair and cleanup. Everything was accomplished per the quote and at the quoted price. Very happy and will recommend Roofstar to any neighbors needing roof work.

I have been so impressed with Roofstar! First let me say I was amazed with Mathew. From the first time he came to our house. Mathew was running about 5-10 minutes late. Mathew called and let me know he was close but would be a few minutes late. He was less than 5 minutes late. What a nice touch! Looking at his age as he appeared young, I wondered how much can he know about roofing? When Mathew came off the roof and explained every picture he took I was impressed. It was obvious he knew how to inspect a roof.

Mathew’s follow up was exactly what he said it would be. This day and age that type of service is hard to find!

On the 2 occasions that I spoke to your staff on the telephone I hung up thinking these employees must love their boss, because they cared so much for his customers.

I don’t make a habit out of sending this type of email, because we just expect good service. Your employees went above and beyond good service.

I look forward to refer friends and family in the future, hoping I never need your service again, but I know where I will call if I need my roof fixed.
