How to Roof a building
A strong roof provides lasting weather protection. Roof keeps out rain, sun and protects a building. In cold climate, roof can also provide insulation to a building.
This Guide is about how to Roof Building. There are 2 types of roofing, flat and pitched roofs types.
Most roof failures occur at bolted connections that were either inadequately secured at the time of construction or that have since failed due to deterioration. Some roof designers often fail to take into account a number of design factors such as tolerance and factors of safety, and these could result in roof failure.
Other factors that could cause failure in roofs are the effects of wind and fire, poor workmanship, age, poor maintenance, height of the building and the use of cheap and substandard materials.
Types of roofing materials
i. corrugated aluminium zinc sheets
iv. slates etc.
Corrugated Aluminium Zinc Sheets
It’s the cheapest compared to the others above but it has the disadvantage of rusting after some time but this takes years, the rust level can become so high that it looks unsightly and if it is not changed by this period, leaks start to occur.
Aluminium Roofing Available in different colours, has a very pleasing and distinct appearance, it’s durable, has long span life, no maintenance required, it’s corrosion resistant, it’s not only used for Roofing but also for cladding and flashings. it’s economical to building construction due to it’s light weight, length are tailor made to specifications.
Roofing tiles is another approach to metal roofing, long-span roofing tiles assure years of reliable performance and Classic appearance, a delight to behold.
Roofing Slate -Is unaffected by extremes of temperature and highly resistant to a range of chemicals. It is impermeable to water and therefore is a perfect roofing material. Cost – the longevity of the material ensures it is a cost effective roof covering as the slates will last the lifetime of the building.
You’ll also need scaffolding, a roofing nailer and work gloves.
Required Materials for this Project
#15 or #30 Felt underlayment
Self-adhesive waterproof underlayment (“ice and water shield”)
Step and dormer flashing
Roofing, do it yourself?
Step 1 – Plan your Job
Step 2 – Strip your Old Roof
Step 3 – Replace or Re-nail your Sheathing
Sheathing is the base of your roof. If you do not plan to put down new sheathing, re-nail the existing sheathing into place. This will insure its durability. Cut out holes in the sheathing where venting will go through.
Step 4 – Install Water Guard
First you put down your ice and water guard for roofing a house. This will help prevent your roof from leaking. It will have an adhesive side. Lay it out over the roof as needed. Make sure there are no gaps in the sealant.
Step 5 – Install Underlayment
The underlayment is your tarpaper. Most roofers use 30-pound tarpaper. They install it with one-inch roofing nails. Sometimes it is okay to use a staple gun. It is generally faster, but not as strong as nails. Apply your underlayment over the entire roof.
Step 6 – Install Flashing
Flashing helps prevent your roof from leaking. It will be applied at any rise in your roof and in corners. Flashing goes around the base of your chimney and other additions in your roof. Cut the flashing to the right size with your tin snips. The middle of your flashing should be in the corner.
Step 7 – Install Shingles
Nail your shingles from one side to the other. Overlay them as necessary and lead them toward the roof’s peak. Lay them out in rows, and then go up a step. Do it until the entire roof is shingled. That is all there is to roofing a house.
How to Install Slate Roofing Shingles with Ease
Slate roofing, when installed correctly, not only adds to the overall appearance of your home, but will hold up to the time of weather and age much longer than average roofing materials will. The average life for slate shingles is well over 100 years, and since the majority of us do not stay in one place longer than that, you will effectively only have to roof your house once while you live there. Of course, these types of shingles take a little more knowledge to install than asphalt shingles do, but the average homeowner can still apply them without having the expense of a professional roofer being hired.
Supplies and Tools You’ll Use:
Step 1: Mark the Runs
After choosing the type of slate roofing that you want to install, measure the runs that you will use when installing the starter row of tiles, making sure that your measurements are accurate and that your lines are straight. The best way to do this is to use a chalk line with a bright color so that it is easily visible. Depending upon the size and brand of the slate tile manufacturer, these lines may be different, so follow the suggestions given with the roofing materials.
Step 2: Drill the Holes
Before beginning to install the slate tiles they need to have holes drilled in them so that you can secure them down to the roof without the chance of breaking them. Once again, the holes will vary depending upon the tile and manufacturer, so follow the given recommendations.
Step 3: Install Starter Row
Begin installing the starter row from left to right on the roof. Make sure that the edges of the tiles overlap the edges of the building by 1.5 inches which will allow the roofing materials to divert water and snow away from the sides of the house. Make sure that when you nail them down that you use strong copper or stainless steel nails that are meant for roofing applications.
Step 4: Install the Remaining Rows
After the starter row is secured in place, measure 2 inches from the top and mark the entire run with the chalk line. Begin placing the next row, using the chalk line as the bottom edge starting point. Make sure that you stagger the pieces so that the joints to not match the preceding row. Continue all the way to the top of the house, staggering the slate roofing tiles so that it forms the pattern that you want.
Step 5: Install Ridge Cap
After both sides of the roof have been covered with the slate roofing tiles, add the ridge cap along the top of the peak. Remember to use a chalk line to ensure that your runs are straight and pre-drill holes so that you can secure the tiles down.
That is all there is to installing slate roofing tiles easily and quickly without having to hire a professional. It is very similar to applying other types of roofing materials, except for the fact that they are slightly harder to work with, and that they have to be pre-drilled before installing them.
