    FAQs

    how to replace flat roof felt?

    How To Replace Flat Roof Felt

    Also referred to as tar paper, roofing felt is installed underneath the roof’s shingles to help deny water access to your home. Installing the roofing felt in overlapping layers builds a water barrier in situations whereby the weather damages or blows away the shingles. Although the application of a roofing felt on a flat roof is relatively easier and safer than working on a peaked roof, it’s advisable to take enough care and precautions. If you lack proper training and experience for this task, we’d recommend you employ a reliable professional to guarantee the best results and save you from further headaches especially in cases whereby unfortunate errors are made. This step by step guide will give you a good insight into the flat roof felt replacement process.

    • Take a measurement of the width and length of the roof.

    • Calculate the square footage by multiplying the numbers.

    • Multiply the square footage gotten by three (it’s advisable to install three layers of roofing felt to create a really strong weather barrier).

    • Use a claw hammer to remove the existing roofing felt.

    • Use utility knife to cut the new felt to fit the length of the roof.

    • Place the first piece along the roof’s edge and use a hammer tacker to tack the felt in place with staples or galvanized nails and hammer.

    • Put the staples or nails at every 6 inches along the side touching the roof’s edge as well as down the short sides.

    • Repeat the same process for the second piece, laying it out beside the first row of felt.

    • Cut a piece of felt to the appropriate length using a utility knife to begin the second layer of roofing felt, and cutting it in half, lengthwise.

    • Apply construction adhesive along the first row using a trowel.

    • Press the first piece for the second layer onto the adhesive. Repeat this process until the roof is covered with a second layer

    • Apply construction adhesive over the second layer to install the third layer. Begin with a full piece of felt without cutting it in half.

    • Overlap each piece by 2 inches until you’ve completely installed the third layer.

    What guarantee or warranty can I get?

    Most material warranties come from the waterproofing layer manufacturers, and can last between 5 and 20 years. If your roofing contractor is on the manufacturer’s installer list, it might cover their work. It’s important that you always read through all the information given to you about your warranty so you know exactly what is included.

    how to replace a flat roof?

    How To Replace A Flat Roof

    Is it high time you replaced your flat roof with a new one? If it’s time, then you probably shouldn’t waste another minute! Flat roofs come with multiple upsides and happens to be a lot more affordable than many other options (especially for starters). Not only do they add to your home’s curb appeal and requires a relatively low labour costs as there are minimal risks involved, but they’re also more accessible for maintenance purposes and aren’t as exposed to damage as a pitched roof. However, we’re not here to discuss the various benefits of installing a flat roof, but rather tell you how to install one. If you lack proper training and experience, we’d recommend you hire a trustworthy professional that can guarantee the best results.

    • Wipe the entire roof system clean.

    • Detach and replace rotted roof sheathings.

    • Detach and replace rotted fascia

    • Hire a qualified air conditioning professional to disconnect the existing AC units.

    • Introduce new aluminium air conditioning stands and secure against the deck.

    • Let you qualified air conditioning professional reconnect the existing AC units.

    • Put in place the new air conditioning quick disconnects.

    • Attach EPS fanfold insulation in such a way to cover the surface of the entire roof and secure it firmly in place.

    • Attach the tie-in roof materials where necessary.

    • Attach roofing membrane to cover the entire area of the roofing.

    • Attach membrane to the entire roof’s perimeter.

    • Attach new perimeter flashings (fascia bar, fascia cap and drip edge), secured on the centre at 6. Make use of a good sealant to secure the fascia bar or fascia cap’s top flange.

    • Attach boots on plumbing seal and stacks.

    • Identify the existing vent stacks and seal, and put curbs

    • Put safety walk pad network from the access point of the roof to the air conditioning units.

    • Attach rooftop signs for roof traffic personnel

    • Tidy up and clear out the debris

    What is overlaying?

    If your existing roof is still in good condition but the membrane is getting old, it’s often not worth exposing the structure to the weather whilst the contractor strips off the old membranes. The contractor will leave them in place to act as a base layer for a new roofing system. As long as there are no other problems with your roof, then overlaying is a good way to replace your flat roof.If you have any more questions about flat roofing that aren’t listed here, fill out our form to ask a contractor.
