"This company was great. They got back to us right away for an estimate and a start date. We had to postpone a week due to rain but Richard contacted us in a timely manner to let us know when the new start date would be. The crew came on time, were very nice, did the work quickly and professionally and cleaned everything up. Richard came by every day to check on it all. We are very pleased with our new roof, patio cover and the whole process."

"We have a historic home and there was additional care required to replace siding beneath the roofing material at the eaves. The team at Jordan roof completed the entire job in only 4 days, they fixed up our dormer which had shingles that had deteriorated, and repainted some of the shingles. Our home looks better than ever! Great responsiveness, fair pricing, and high quality work."

"We are giving Hoyt Roofing a 5 Star rating, because of the excellent job they did on the installation of our new roof. The whole process only took four days and the workers went over and above to keep us informed of the progress and maintaining a clean work area. We were impressed from the initial meeting where we discussed and deciding on the terms and conditions to completion of the job. They were not pushy or try to upsell their products. We highly recommend this company to anyone who needs a new roof."

Roofing questions, answered by experts

Roof raking can damage shingles if improperly done. Be sure to use a rake that’s designed specifically for removing snow from a roof, and don’t use excessive pressure. Light, consistent pressure to pull down the bulk of the snow is all that’s needed—if you clear right down to the shingles, you’re probably using too much force and risking roof damage.

The best way to check if a roofing company is legit is by asking the roofer for their license number. They should have no issue providing you with this information if they’re legitimate. You can also look to see if they have an online presence, read reviews, and ask contractors you’ve worked with before if they know the roofing company.

If a roof is not vented, trapped air and moisture have nowhere to go and will cause moisture to build up in the attic. When moisture builds up, it can cause mold and mildew, leaks, and rot. It will make the space hot and stuffy, which can result in higher energy bills as the HVAC system works overtime to regulate the temperature.

It’s the reverse of home de-winterization. To winterize, you purge your plumbing system (including your water heater and all piping) of water. Some experts also recommend filling fixtures with an antifreeze solution. Other tasks involve winterizing sprinklers, sealing foundation vents, check weatherproofing around doors and windows, and more.

You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.
