"After a bad experience with another contractor, I turned to Dalmatia Roofing. Paul & his crew were different professional, efficient, and dedicated to quality. They restored my trust in roofing services, and I'm grateful for their help."

"called Arian about a roof repair, he came next day . He gave me a good estimate for the repair, after discussing the repair we talked about a new roof because the roof was over 30 years old. He gave me a good price. He and his 5 guys came 2 days later. They finished the job in 6 hours did a good job at a fair price and left the property in clean condition"

Roofing FAQs, answered by experts

To apply for a roofing permit, contact your local building authority. You may visit their office in person or contact them via phone or email. For more information on how to start the process, visit their website.

Though roof coatings can last up to two decades, it’s a good idea to recoat your roof every four to six years. This is especially important if you have a built-up roof, which is vulnerable to moisture issues. Inspect your built-up roofs annually to make sure they don’t need a new coat.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.

You only need to replace a roof before moving if it’s extremely old or has more than just a couple minor damages. For instance, leaks, uplifted shingles, or obvious holes are issues no one wants to deal with right when they move in, and will automatically repel potential buyers that might have otherwise been interested.

A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.
