Get matched with top chimney cap pros in Jesup, GA

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. 

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.

The cost to replace a roof averages around $9,200, and most people pay between $6,000 and $15,000. The size of your roof plays a major role in the total cost, but the most significant factor is whether you need new shingles placed over your old roof or a full replacement. The former is possible until you have three layers of roofing on your home, and it’s more affordable. A full replacement involves ripping off old layers of shingles, sometimes repairing the sheathing, and then laying down a new roof, which is the most expensive project.

While you can technically install TPO roofing over an existing roof, it isn't always wise to do so. The more layers of material you add to your roof, the more weight it must support. You may also develop moisture issues by covering your existing roof with TPO. Your local building codes and regulations may actually require you to remove the existing roof before adding TPO, so check with your local municipality.
