8. What tarp to use?
Tarps or tarpaulins are made from plastic. They are waterproof and sold in various sizes. They have ring openings around their perimeter for fixing ropes or weights. You can buy them online or at any hobby market or hardware store.
And to finalize, here are some extra tips on how to be prepared during seasons of rain and storm:
- Choose the right tarp - Don’t try to save money on the quality of the tarp. The tarp should be durable, waterproofed and UV resistant for a long time.
- Think about tarp size - This depends on the area of the exposed roof in need of protection. The tarp must be oversized to account the overlap on the sides and edges of the roof deck. Two or three tarps may be required.
- Be prepared, have a stock of wooden battens, screws, a screw-gun and some weights - For weight, you can use full unpacked bundles.
- Install the tarp - Secure one side first and make sure the tarp is the right side up. Pull tight and remove all wrinkles. Then put bundles on the ends and secure them with battens and screws.
- Silver heavy-duty duct tape - If the tarp gets punctured in some way you can tape it on the underside.
- Cover the underlayment with the tarp - When you leave the job, cover your underlay with a tarp to protect it against moisture. Next morning you can start installing shingles on a dry underlay without any wrinkles.
How roof professionals can handle extreme weather situation during roof application:
Each roofer has his own tricks on how to protect the roof from sudden rain. For locations close to the sea or ocean, heavy rain showers are very common throughout the year. Roofers cannot wait too long for a dry period, so they build a superstructure or temporary roof over the working area to be able to carry on working while it is raining.
Many responsible roofers are prepared for all these emergency situations but it’s also good to have roofers liability insurance. As a busy professional, they need to be insured so they can focus on their work with the confidence of a solid coverage behind them.
So don’t hesitate to start the renovation or the new project if there is some rain in sight. Take the right precautions and you will be able to get a lot of work done in a safe way!

A safe and healthy roof is a crucial part of each building. When one or more of the following roof problems occur, we know that the safety of your roof is at risk:
- A leaking roof
- Deteriorating roofing materials
- The roofing materials are moving or shifting to an accepted degree, or the shape of material is changing.
- The roof has an unsightly appearance.
The causes of roofing and flashing problems usually spring from design, from the materials selected by the builder or architect, and finally from the way the contractor applied the roofing and flashing.
Moisture and Roofs
Contemporary architects and building engineers recognize that their systems are vulnerable to moisture due to 3 sources:
- Rain penetration
- Entry of water vapor
- Ice damming
To avoid these dangerous situations, certain building science principles behind the problems of moisture and roofing should be understood.
Rain Penetration
Roofs leak when water finds an opening and sufficient force is applied to drive the water inwards. To eliminate rain penetration the roofer must either close the openings or neutralize the driving force. A sloped bitumen shingle roof seldomly leaks because gravity offsets the forces acting to move the water inward. Overlapping the shingles limits the direct entry of rain drops by impingement.
Gravity acts to move water outward down the roof slope. The greater the vertical height of the shingle lap, the greater the gravitational force. Leakage occurs when the roof is not sloped enough to let the force of gravity resist the wind force driving the rain through the openings. Generally, the only way to control water penetration on low slope roofs is by applying a continuous waterproofing membrane.
