When you plan your budget for new roofing or guttering material, make sure to include things such as flashings, roofing cement and even nails. Flashings can be used for several parts of the roof area. The one most commonly used for chimneys, drip edges, valleys and vents are made of malleable, galvanised steel (28-gauge). If you have an asphalt shingle roof through you can use mineral surface roll roofing on valleys and vents. Another material than can be used is plastics and aluminium – even copper can be used for chimney flashings if you so prefer. Preformed flashings for drip edges, valleys and vents are available to purchase or if you are handy, you can make them yourself. These materials can be purchased from any good diy store.
Materials for the Job
Plastic roofing cement is another product that you will need if repairing or replacing a roof or gutter. It is a black and elastic waterproofing agent that you use under shingles, along flashings and between the different layers of felt. Plastic roofing cement comes in caulking tubes or in different size cans. Depending on what type you buy, you will need to apply it with either a caulking gun or a steel trowel.
A lot of people looking to do repairs to existing roofs or laying a new one forget to include the cost of nails to their budget. This might look like a minor thing but if you consider how many nails you will have to use to do the job – especially if you are working on a bigger surface or replacing the entire roof – the cost can creep up on you. Depending on the nature of your roofing project, you will need different type and size of nails. For underlayments and roof surfaces, it is best to use hot-dipped galvanised nails as these do not rust through and damage the surrounding materials. Remember to buy long enough nails so that they can penetrate roughly ¾ of an inch into the roof deck or if you use plywood sheathing – all the way through. When applying sheathing it is generally ok to use common nails or box nails and these are a cheaper option as well.
A quick way to apply shingles is to use a pneumatic staple gun but please check whether your warranty covers application with staples, otherwise stick to using nails. Keep in mind that if you do not know how to use a pneumatic staple gun correctly, the staples might not fasten the shingles securely to the deck or they can break through the asphalt. You can imagine how catastrophic the result from this might be.
