"We had a great experience with On Top Roofing. They returned my call for a quote request within one day and had someone out to give an estimate within a couple of days after that. We obtained several estimates, On Top was the only company that actually climbed up on a ladder to really look at the area of concern and where work needed to be done during the estimate. After we received the quote, the work was done within the scheduled time and completed as agreed. I would definitely consider On Top again for future roofing needs."

"Matt sat down and explained everything from start to finish, before any work was to begin. The workers were very kind and made sure they cleaned up immaculately. Once the roof was complete Matt made sure we were 100% happy. We would highly recommend MTS Siding and roofing."

"I had a great experience with Global roofing. Fredy was quick to get back to me to set up a time to meet and assess the issue. He was very easy to communicate with throughout the process. The job was completed in one day and they cleaned up thoroughly. I would highly recommend Global roofing and will use them again in the future."

"Quick response to repair leak which was great because heavy rains were on the way. Partial roof replacement was very conveniently scheduled around the weather and my and my tenants availability. Work was completed in less than a full day. They cleaned up well. No mess left outside the house or on the porches (3 family house)."

Customers say: True professional

"The roof was patched and I no longer have a leakage problem, I provided the wrong Shingles which were used unfortunately, and as a result the finished look is relatively poor, The company was very responsive and if they had the correct materials I'm sure the job would have been more than satisfactory. I need to remember it was a patch not a new roof. Try them, they came out between rain storms and fixed my leak."

"They beat out the local contractors by quite a bit. I was able to get the roof done plus gutters for less than what the locals were trying to charge just for the roof. Very easy transaction, they were in and out and the day and they cleaned up their mess. The roof looks fabulous!"

Roofing FAQs, answered by experts

Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting alternative roofing materials, where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. 

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

The most crucial roof-strengthening method is achievable by following proper construction methods and guidelines from the start. To strengthen an existing roof, framers and DIYers can add hurricane ties or straps to the structure, sister rafters and other framing or truss members, or install additional fasteners or adhesives where necessary.

Roof repairs average around $1,100 but can easily exceed that for larger repairs. The cost of roof replacement depends on the size of your home and the materials used but averages between $4,000 and $24,000.

The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.
