This project with show you how to handle a short-term roofing need using rool roofing.
For a utilitarian solution when appearance isn't as important, consider roll roofing, which is made of materials similar to composition shingles but generally not as durable. Be sure to check the warranty, which may be for only one year. If you install roll roofing using the double-coverage method, it will last longer.
Roll roofing is often installed over bare wood sheathing or sheathing that has been painted with a primer. Applying roofing felt first will better protect the sheathing against condensation, as well as against leaking.
If the roof is sloped, you can use the exposed-nail method. For a slightly sloped roof, use the concealed-nail method shown in the box, below right. For a flat or nearly flat roof, use double coverage, although a torch-down modified bitumen or EPDM roof is a better solution.
Prestart Checklist
Time
Working with a helper, half a day to install flashings and roll roofing for a 700-square-foot roof with modest complications
Tools
Hammer or power nailer, tape measure, flat pry bar, carpenter's square, tin snips, utility knife, chalkline, broom
Skills
This is the least difficult of roofing materials to install: Only basic carpentry skills are needed.
Prep
Prepare the roof by tearing off the old shingles, or by preparing for a reroof.
Materials
Flashing, nails for flashing, roofing felt or primer, perhaps WSU for the eaves, roll roofing, nails long enough to poke through the sheathing, roofing cement
