"On Top Roofing is Top of the Line Roofer. Professional delivery with solid quality! Company was hired to correct the issues caused by a prior roofer whose incompetence has cost me additional thousands in repair. On Top Roofing installed a ridge vent that the prior roofer only placed on the roof, re-flashed the chimney where prior roofer failed to install to match new rook lines, re-surface flat rook where prior roofer ignored. In addition, On Top Roofing was used on apartment buildings to help close up the roof and eliminate a bat problem. On the Top Roofing is the only roofing company to use. It takes a while to get on their schedule, but they show when they say the will and do the job they say they will do. Only hire On the Top!! You will not regret."

"I recently had Ranch Roofing install a new roof on my home and I am so grateful I chose them! I honestly cannot say enough good things about this company. From the very beginning, when I was searching for a roofing company, choosing a shingle color, and asking questions (since I know very little about roofing), the entire experience was wonderful. They were patient, knowledgeable, and always took the time to answer my questions and make sure I understood everything. The process was easy and stress-free. On installation day, the crew arrived, put up the tarps, and got right to work. The old roof came off, the new roof went on, and the results are absolutely beautiful! I chose Onyx Black, and I am so glad I did. It looks sharp! The new intake vents and ridge vents were also installed, and everything looks amazing. I had read about their reputation and how they stand behind their work, which gave me confidence in choosing them. They certainly lived up to that reputation. They are wonderf"

"It went very well.  The owner, Richard Farina, suggested using an "architectural" shingle, which is heavier and should last for 30 years as opposed to 20 for most other types of shingle.  They installed Grace ice and water shield up to a distance that we requested.

We had one small leak this past storm on the front porch from the front corner of our bedroom dormer.  They were very responsive and came back the same day called and applied additional caulking between the roof shingles and the siding shingles, where a gap had been created.  I was pleased with their prompt responsiveness."

"We chose Conde Roofing to replace the roof on our 130-year-old home. Mel was great to work with. He was dependable and clear in his explanations during the estimate and coordination of the job, and a pleasure to do business with. The large crew worked like a well oiled machine, completing the entire job in one day. The clean-up was meticulous - not a nail or scrap in sight by the time they were done. We are so pleased with the beautiful new roof and we’re 100% satisfied!"

"The work was done by conscientious, detail oriented professionals. The site was kept safe and clean during the job. I would not hesitate to recommend Exteriors Unlimited to anyone looking for roofing or other exterior work. I even booked them to re-side my house which was completed with the same meticulous attention to detail."

Roofing FAQs, answered by experts

Whether replacing the entire roof or just installing roof shingle replacements in small areas, always pull up the old roof shingles. While you can technically put new roof shingles (but not other roof materials) over old shingles, this can add weight strain to the roof and prevent the new shingles from securing properly to the roof.

After you take steps to determine when your roof was last replaced, you may realize you need a new one. Hiring a roofing contractor you can trust involves asking for references and examples of past work. Verify any qualifications the roofer provides. Ask about the expected time to complete the work and about putting guarantees in writing.

The easiest type of roof to build is a shed-style or lean-to roof, which features a single sloping plane from one side of the building to the other. Unlike a gable roof with two sides meeting in the middle, a shed roof's single slope makes the construction process more straightforward. The rafters are typically single pieces of wood that span the distance, often without the need for additional supports.

Condensation can occur on the inside of a roof, but it should always be temporary. It does not necessarily mean there is a roof leak. Condensation happens when the inside and outside of a house are at different temperatures. For instance, if it is hot during the day and then gets very cold at night, the inside of the house will be warmer than the outside and may cause condensation to form on the inside of the attic. This may not be cause for concern, but if it is happening frequently, it should be addressed; otherwise, it could cause roof leaks, compromise the structural integrity of the wood, or allow mold to grow.

Asphalt shingles, wooden shakes, and slate or clay roofing tiles are often replaceable without having to replace the entire roof. It's possible to replace just a few shingles or tiles without much trouble in the case of wind damage or other minor problems. DIYers can perform the task in some situations. However, professional repair is always the best bet when it comes to roofing.
