Concise Roofing Basics in Oahu, Hawaii

These roofers are professional and if working in a crew may finish a moderate sized home in 3 to 4 days. They can work in small stretches of decent weather and work right up until the snowflakes fall.
Replacing a roof in Oahu.
If you decide to do it yourself with the help of friends, you have to make some decisions first. What materials will you need? If you have an asphalt roof and want to replace your roof with asphalt, a lot of the questions are answered. Asphalt shingles are by far the most popular but also the less attractive.
Metal roofing is currently becoming more popular. It comes in aluminum and steel. It has the advantage of being fire proof and lasts forever A drawback is that most metal roofs required a professional roofer.
Slate or Stone Roofing
Usually fireproof it is high end roofing. It is also very heavy. Slate and stone are quite petty roofing and will enhance the looks and maybe the quality of your home. A second form of slate roofing now exists of 95% recyclable material. It is also heavy but lighter than regular slate or stone. It is cheaper and lasts a long time. Real slate stone also lasts a long time. Slate is more difficult and more expensive to repair.
Clay or Ceramic Roofing
These tiles, especially the orange colored Spanish looking tiles or half barrel tiles, so named because they are a circle sliced in half by shape, are predominant in southern California and Florida. Ceramics have taken a huge step in strength of the material in the last years. These tiles are fire retardant and are lighter than slate or rock. But they are still heavy.
Weight is a very important aspect of roofing. It is important that you don’t select shingles that are too heavy for the under laying structure. It is important here to determine whether the present shingles will be left in place and the new roof set over it or whether the present roofing will be removed. Roofs are weighty. Two or three roofs layered with a new roof may be too much weight. Another concern is any damage or irregularities of the existing roof. Roof Repair must be accomplished before the new roof is laid over the damage making them larger by putting new materiel on top. This will not be too difficult but will take time.
If you are going to remove the existing roofing it will take you some time. Here a Roofing Contractor will be valuable. Doing it yourself takes time, perhaps several days, and is labor intensive. Having Roofers doing it requires only a morning on a medium sized home.
When removing the roofing, flashing and drip edging must also come off. Next replace rotted or damaged wood with plywood sheeting or sheathing boards.
Ready for Additions
Your roof may need ice dams if your region has snowy temperatures and plenty of snow. It is a guard against snow and ice backing up penetrating shingles and causing leaks and damage.
Next comes asphalt felt roofing paper which is overlapped and worked upwards, starting at the roofs edge. It should be flung over the hip. This can be stapled or tacked.
Add metal drip edging around the edge of roof. Valley flashing should be placed where two planes of the roof meet. Try to apply in one strip. Also apply flashing anywhere the roof might leak, like at chimneys.
Lastly, you are ready for the shingles. Snap a line from the middle of the roof down to your starting point. From this line begin to go one way on one side and the other way on the other side. Starting at the edge of the house, flaps will hang over in front and back which must be cut off. Start 3 inches in from flashing. Leave overhang at either end and cut these off with a hook blade attached to a utility knife.
Roof vents or vents at the hip of roof allow ventilation, relieving heat and cold from the attic. These can be installed as you go. Older houses may not have vents and new ones must be added.…
