"I paid $62000 to have my roofs repaired - not cheap for a disabled person. Hopefully, thei dropping the ball is not because Im disabled. They removed but did not properly reattach my ATT line to detached garage. Also, there was a fluke rainstorm about 1-1/2 weeks ago and i heard a dripping sound in / near chimney. I complained and Brent Eikanas their contact promised to have supervisor here to check leak TODAY between 10-11 am and anchor the ATT connection like it was before they removed it. They no-showed AGAIN. I had to remind them of other items they needed to do to finish/using my payment as leverage - removing the old gutter all the way - they had only half-way removed it. I have photos and next winter will have to video and record leak in/near fireplace. I had to start documenting because phone call is useless. The workers left nails and some trash too and on Cinco de Mayo, their last day here, they did two structures in 4 hours,"

Roofing questions, answered by experts

Metal roofs do not technically require a drip edge if the roof overhangs at least one inch, because the roof's slant will cause water to flow away from the structure. But a drip edge would be an added level of protection for a metal roof to help keep moisture issues at bay.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.

Roofers can install roof vents. Updating, upgrading, or simply replacing your roof's existing vents is common when installing a new roof. If you're looking to upgrade your ventilation system with a powered version, a local HVAC professional can also help with the task. If adding roof vents to your home is necessary while installing an addition or during other renovation work, your contractor will handle or hire out the venting work.

To cap off a chimney flue, start by measuring its width, length, and diameter, if it’s circular. Purchase a cap that fits the flue, and decide whether you want a temporary or permanent model. Then, slide or insert the cap onto the flue and secure it with a screwdriver. Be sure to avoid over-tightening the screws to prevent chimney damage. 

Many states require roofers to be licensed, and some states don’t mandate licensing. You can use Angi’s state licensing tool to check if a roofing company holds the proper licensing for your area. A licensed roofing contractor will provide reliable roof installation service, leading to a reduced risk of leaks in the future, which can be expensive to repair. Paying more for a licensed roofer upfront often means paying less over time.
