subject: How About Home Improvement You Haven't Thought Of? A New Roof! [print this page] If the roof over your head lasts as long as you own the home, all the better. But that is not always the case. Every 20 or 30 years, sometimes sooner, homes need their roofing either replaced or reinforced.
A homeowner that suspects it is time to install a new roof needs to be sure. In this homeowner's guide to residential roofing, you will learn some of the basic symptoms of a roof in need of replacement. Followed by that will be a brief outline of the work necessary to properly install a new roof, including the extensive preparations. Also covered are some of the roofing features available like a drip edge and an ice shield. Let's get to it.
How do you know if it's time for a new roof?
If your roof is leaking it will be obvious. Stains on the ceiling inside are a tell tale sign. Sometimes, though, a leak in the roof can be repaired locally without the entire roof being replaced. For the big picture, look for a combination of factors including the following:
*Algae growth - Airborne algae produce a dark discoloration on the roof that resembles soot or dirt.
*Curling, blistering, or missing shingles - These can be caused by moisture, poor workmanship, or high winds.
*Damaged flashing - This is caused by drying or cracking on an old roof, improper nailing, or settling of the home over time.
*Buckling - Buckling can happen when the house settles, if new shingles are applied over old ones, or because of poor workmanship. Poor workmanship includes improperly applied felt, wrinkeld underlayment, or lack of spacers between the roof deck and boards.
*Missing granules - Granules naturally wear off of shingles, but if there are so many loose granules that they are filling up your gutters or if the mat underneath is exposed, then your shingles have officially gotten too old.
*Signs of rot - This is more common in organic base shingles. Consider replacing with fiberglass shingles to avoid rot.
What does it take to install a new roof?
A good roofing crew will have a system in place when you order your new roof, including preparation. Without undergoing significant preparation, a homeowner risks the integrity of their new roof. If a roof is poorly prepared, it will quickly develop crack, holes, and eventually leaks.
Typically, the team will take up most of your yard, laying out the new roofing materials. Also they usually pull a dump truck up to the side of the house to throw in all of the old roof detritus that will be torn off and trashed. If you cringe at the thought of a heavy dump truck crushing your lawn, ask your roofer about a new technology called Mr. Buggy, which is a great dump truck alternative. The team will remove all the old shingles and pull out the old nails. At this stage it is time to replace or secure the roof boards. Each roof board should be inspected individually to ensure the future integrity of the new roof.
All debris must be removed from the roof at this point, because demolition will be over. It will be time to begin the actual installation portion of the roofing project. Next the team must install an aluminum drip edge along the eaves of the roof using galvanized nails to prevent rust. After the drip edge, it is wise but not necessary to install an adhesive ice and water sheild. This can be expensive but it is well worth it in wet or cold climates. Some states' building codes require the ice and water shield, so do your homework.
Then the team will entirely cover the roof area with felt or roofing paper in overlapping rows from the bottom up, fastening it down with roofing tacks. Finally the new shingles are attached, from the bottom corner of the roof up to the very top. Any hips and valleys are overlapped, using a herringbone technique.
It's over now. Congratulations!
Roofing is arduous work, requiring lots of manpower, that is best handled by professionals. Roofing requires a significant amount of demolition and preparation before the familiar shingles or shake are fastened down. It sounds simple here, but it takes days, and it is a very dirty and labor intensive job. The good news is that when the roof is done, it looks so ordered, fresh and beautiful that the whole house seems to smile to be wearing a new top. And as a homeowner, you are allowed decades of cozy security under a healthy new roof.
